Metho...Objectives: To assess the efficiency in terms of cost-effectiveness (CE) of oral Renalof® treatment versus extracorporeal shockwave lithotripsy (ESWL) in the treatment of kidney stones ≤ 1 cm in Nicaragua. Methods: A cost-effectiveness economic evaluation was carried out based on the results obtained in the randomised, prospective, observational, single-blind, prospective, phase 2 clinical trial. Cost-effectiveness and the incremental cost-effectiveness ratio (ICER) were calculated. Economic data were obtained from the Economics Department of Clínica Senior in Managua, Nicaragua. The monetary cost was expressed in US dollars (USD). Results: Treatment with Renalof® yielded a CE of $1,323.08/% remission, while ESWL was $9,498.54/% remission. The ICER shows that, in order to achieve a high percentage of kidney stone remission with ESWL, an extra $4,734.70 per patient must be invested. Conclusions: The use of Renalof® is shown to be a more cost-effective option than ESWL. It is recommended for the treatment of kidney stones ≤ 1 cm in size.展开更多

Methods: A total of 50 COPD patients were selected between January 2023 to December 2023 and randomly grouped into an observation group and a control group, with 25 cases. The observation group was given extracorporeal diaphragm pacing combined with a noninvasive ventilator, while the control group was given a conventional treatment mode. After the treatment, the results of each index in the two groups were compared. Results: Compared with the diaphragm function indexes of the two groups, the data of the observation group were more dominant (P < 0.05). The rehospitalization rate of the observation group was lower than that of the control group (P < 0.05). The COPD assessment test (CAT) and mMRC (Modified Medical Research Council) Dyspnoea scale scores after treatment between the two groups were significantly different (P < 0.05). Compared with the control group, the lung function indexes of the observation group were more dominant (P < 0.05). Conclusion: Extracorporeal diaphragmatic pacing combined with a noninvasive ventilator promoted the improvement of the patient’s prognosis and improved their respiratory function.展开更多

Methods: Ninety-seven MACP patients admitted to our hospital from September 2021 to September 2023 were randomly selected and were divided into Group A (control group, 46 cases, rehabilitation training treatment) and Group B (observation group, 51 cases, extracorporeal shock wave with rehabilitation training treatment), and outcomes of the two groups were compared. Results: The treatment efficiency, post-treatment clinical indexes (upper and lower limb function scores, activities of daily living (ADL) scores, visual analog scale (VAS) scores), and short-form 36 (SF-36) scores of Group B were better than those of Group A (P < 0.05). Conclusion: Combined extracorporeal shock wave and rehabilitation training treatment for MACP patients improved their limb function, daily activities, quality of life, and reduced pain.展开更多

Method...Objective: To compare the effects of extracorporeal membrane oxygenation (ECMO) and routine mechanical ventilation on mortality and the risk of associated adverse events in patients with severe viral pneumonia. Methods: PubMed, the Cochrane Library, Embase, Web of Science, and other databases were searched to collect case-control or cohort studies on prognoses associated with ECMO treatment for viral pneumonia. Search terms included extracorporeal membrane oxygenation, ECMO, viral pneumonia, COVID-19, influenza, MERS, and others. According to the PICOS principle, two evaluators independently screened the literature, extracted the data, cross-checked the data, and extracted the data again. Two researchers evaluated the risk of bias in the included studies according to the Newcastle-Ottawa Scale (NOS) and cross-checked the results. Meta-analysis was performed using RevMan 5.3 software. Results: Nine studies were included for analysis, encompassing a total of 4,330 patients, which were categorized into ECMO and CMV groups. There were no significant differences between the two groups in most baseline data;however, the ECMO group had a lower oxygenation index, and some studies reported higher SOFA scores in the ECMO group compared to the CMV group. There was no significant difference in in-hospital mortality between the two groups. The length of ICU stay, total hospital stay, and total mechanical ventilation time were longer in the ECMO group than in the CMV group. In terms of adverse events, there was no significant difference in the occurrence of kidney injury between the two groups. Bleeding events were reported in two studies, with more bleeding events occurring in the ECMO group. According to the subgroup analysis of different virus types, there were no statistical differences in the above aspects among patients with swine flu, novel coronavirus, and MERS. Conclusion: ECMO has a certain degree of positive significance in the treatment of severe viral pneumonia, but there is no significant difference in the treatment outcome of ECMO across different epidemic periods. The timing of ECMO treatment, patient management, and withdrawal evaluation still need further research.展开更多

文摘BACKGROUND Most species of aconite contain highly toxic aconitines,the oral ingestion of which can be fatal,primarily because they cause ventricular arrhythmias.We describe a case of severe aconite poisoning that was successfully treated through venoarterial extracorporeal membrane oxygenation(VA-ECMO)and in which detailed toxicological analyses of the aconite roots and biological samples were performed using liquid chromatography-tandem mass spectrometry(LC-MS/MS).CASE SUMMARY A 23-year-old male presented to the emergency room with circulatory collapse and ventricular arrhythmia after ingesting approximately half of a root labeled,“Aconitum japonicum Thunb”.Two hours after arrival,VA-ECMO was initiated as circulatory collapse became refractory to antiarrhythmics and vasopressors.Nine hours after arrival,an electrocardiogram revealed a return to sinus rhythm.The patient was weaned off VA-ECMO and the ventilator on hospital days 3 and 5,respectively.On hospital day 15,he was transferred to a psychiatric hospital.The other half of the root and his biological samples were toxicologically analyzed using LC-MS/MS,revealing 244.3 mg/kg of aconitine and 24.7 mg/kg of mesaconitine in the root.Serum on admission contained 1.50 ng/mL of aconitine.Beyond hospital day 2,neither were detected.Urine on admission showed 149.09 ng/mL of aconitine and 3.59 ng/mL of mesaconitine,but these rapidly decreased after hospital day 3.CONCLUSION The key to saving the life of a patient with severe aconite poisoning is to introduce VA-ECMO as soon as possible.
文摘BACKGROUND Venovenous extracorporeal membrane oxygenation(V-V ECMO)has become an important treatment for severe pneumonia,but there are various complications during the treatment.This article describes a case with severe pneumonia success-fully treated by V-V ECMO,but during treatment,the retrovenous catheter,which was supposed to be in the right internal vein,entered the superior vena cava directly in the mediastinum.The ECMO was safely withdrawn after multidiscip-linary consultation.Our experience with this case is expected to provide a reference for colleagues who will encounter similar situations.CASE SUMMARY A 64-year-old man had severe pulmonary infection and respiratory failure.He was admitted to our hospital and was given ventilation support(fraction of inspired oxygen 100%).The respiratory failure was not improved and he was treated by V-V ECMO,during which the venous return catheter,which was supposed to be in the right internal vein,entered the superior vena cava directly in the mediastinum.There was a risk of massive mediastinal bleeding if the catheter was removed directly when the ECMO was withdrawn.Finally,the patient underwent vena cava angiography+balloon attachment+ECMO with-drawal in the operating room(prepared for conversion to thoracotomy for vascular exploration and repair at any time during surgery)after multidiscip-linary consultation.ECMO was safely withdrawn,and the patient recovered and was discharged.CONCLUSION Patients may have different vascular conditions.Multidisciplinary cooperation can ensure patient safety.Our experience will provide a reference for similar cases.

文摘BACKGROUND Venoarterial(VA)extracorporeal membrane oxygenation(ECMO),an effective short-term circulatory support method for refractory cardiogenic shock,is widely applied.However,retrospective analyses have shown that VA-ECMO-assisted cases were associated with a relatively high mortality rate of approximately 60%.Embolization in important organs caused by complications of left ventricular thrombosis(LVT)during VA-ECMO is also an important reason.Although the incidence of LVT during VA-ECMO is not high,the consequences of embolization are disastrous.CASE SUMMARY A 37-year-old female patient was admitted to hospital because of fever for 4 d and palpitations for 3 d.After excluding the diagnosis of coronary heart disease,we established a diagnosis of“clinically explosive myocarditis”.The patient still had unstable hemodynamics after drug treatment supported by VA-ECMO,with heparin for anticoagulation.On day 4 of ECMO support,a left ventricular thro-mbus attached to the papillary muscle root of the mitral valve was found by transthoracic echocardiography.Left ventricular decompression was performed and ECMO was successfully removed,but the patient eventually died of multiple cerebral embolism.CONCLUSION LVT with high mobility during VA-ECMO may cause embolism in important organs.Therefore,a"wait and see"strategy should be avoided.
文摘BACKGROUND The MANTA vascular closure device(VCD)represents a novel approach to achieving hemostasis after large-bore femoral access procedures.Numerous clinical studies have evaluated the efficacy of the MANTA device across a range of patient populations undergoing different procedures.However,there is still a paucity of data available concerning the use of MANTA devices in aiding the decannulation of venoarterial extracorporeal membrane oxygenation(VAECMO).AIM To present our single-center experience of utilizing the MANTA VCD in patients undergoing this procedure.METHODS This single-center study included all patients undergoing percutaneous decannulation of femoral VA-ECMO using the MANTA plug-based VCD between January 2021 and October 2023 at University Hospitals Cleveland Medical Center.Inclusion criteria were adult patients who required prolonged(>24 hours)hemodynamic support with VA-ECMO.Outcomes included all-cause mortality,hemostasis,bleeding,limb ischemia,and site infection.RESULTS This is a retrospective cohort study of 19 patients with a mean age of 56.8 years.Twelve of them were males with a mean body mass index of 29.The most common extracorporeal membrane oxygenation indication was acute coronary syndrome complicated by cardiogenic shock at 36.8%.The mean length of intensive care unit stay for these patients was 18.8±8.42 days.Seventeen out of 19 patients survived to discharge.The MANTA device was successfully deployed in 19 patients,with 10 procedures conducted at the bedside and 9 in an operating room setting.Complete hemostasis was achieved within 5 minutes of MANTA deployment in 17 out of 19 patients.In 2 patients manual compression after Manta deployment was required to achieve adequate hemostasis.Additionally,acute lower extremity ischemia was noted in two patients,necessitating endovascular interventions.No infections were reported at the site of MANTA deployment.CONCLUSION Overall,based on our experience and that of other centers,the MANTA VCD has proven to be a simple,safe,and effective percutaneous technique for facilitating in the OR,but most of all it opens the opportunity for bedside VAECMO decannulation.Post-decannulation ischemic complications are higher in this series of sick patients when compared with elective procedures like transcatheter aortic valve replacement and endovascular aneurysm repair.Additionally,operators should be mindful of the incidence of ischemic complications.Distal Doppler pulse signals should always be checked,to indicate bailout options when this occurs.

文摘BACKGROUND Venous air embolism(VAE)is a potentially lethal condition,with a reported incidence rate of about 0.13%,and the true incidence may be higher since many VAE are asymptomatic.The current treatments for VAE include Durant's maneuver,aspiration and removal of air through venous catheters,and hyperbaric oxygen therapy.For critically ill patients,use of cardiotonic drugs and chest compressions remain useful strategies.The wider availability of extracorporeal membrane oxygenation(ECMO)has brought a new option for VAE patients.CASE SUMMARY A 53-year-old female patient with VAE presented to the emergency clinic due to abdominal pain with fever for 1 d and unconsciousness for 2 h.One day ago,the patient suffered from abdominal pain,fever,and diarrhea.She suddenly became unconscious after going to the toilet during the intravenous infusion of ciprofloxacin 2 h ago,accompanied by nausea and vomiting,during which a small amount of gastric contents were discharged.She was immediately sent to a local hospital,where cranial and chest computed tomography showed bilateral pneumonia as well as accumulated air visible in the right ventricle and pulmonary artery.The condition deteriorated despite endotracheal intubation,rehydration,and other treatments,and the patient was then transferred to our hospital.Veno-arterial ECMO was applied in our hospital,and the patient's condition gradually improved.The patient was successfully weaned from ECMO and extubated after two days.CONCLUSION ECMO may be an important treatment for patients with VAE in critical condition.

文摘BACKGROUND Extracorporeal membrane oxygenation(ECMO)is a new type of extracorporeal respiratory and circulatory assistance device.It can drain venous blood out of the body and inject it into veins or arteries after being oxygenated by an oxygenator(membrane lung)to replace lung and heart functions in a short time.ECMO can provide tissue blood perfusion and gas exchange almost equivalent to cardiac output and extend the effective treatment time window for patients with acute circulatory failure to restore cardiopulmonary function.CASE SUMMARY We report a case of an 81-year-old woman who underwent whole cerebral angiography,basilar artery thrombectomy and stent thrombectomy in the posterior artery of the left brain after implantation of ECMO.The patient was admitted to the hospital due to myocardial infarction.Considering that the cause of the patient’s disturbance of consciousness was unknown and cerebrovascular accident could not be ruled out after the implantation of ECMO,the department of Radioactive Intervention performed cerebral angiography.And the result of the angiography indicated vascular occlusion.After the basilar artery thrombectomy and stent thrombectomy in the posterior artery of the left brain,the patency of the occlusive vessel was achieved.CONCLUSION Although the patient eventually died of circulatory failure,the result of this case verifies the feasibility of cerebral angiography and thrombectomy in patients with implanted ECMO in the intubated state.
文摘BACKGROUND Neurological complications are common in the management of venoarterial extracorporeal membrane oxygenation(VA-ECMO),with most patients requiring sedation and intubation,limiting the assessment of neurological function.Therefore,we must rely on advanced neuroimaging techniques,such as computed tomography angiography(CTA)and computed tomography perfusion(CTP).Because ECMO changes the normal blood flow pattern,it may interfere with the contrast medium in some special cases,leading to artifacts and ultimately misleading clinical decisions.CASE SUMMARY A 61-year-old man presented to a local hospital with chest tightness and pain 1 d prior to presentation.The patient was treated with VA-ECMO after sudden cardiac and respiratory arrest at a local hospital.For further treatment,the patient was transferred to our hospital.The initial consciousness assessment was not clear,and routine CTP was performed to understand the intracranial changes,which suggested a large area of cerebral infarction on the right side;however,the cerebral oxygen was not consistent with the CTP results,and the reexamination of CTA still suggested a right cerebral infarction.To identify this difference,bedside transcranial Doppler was performed,and the blood flow on both sides was different.By reducing the ECMO flow,CTP reexamination showed that the results were normal and consistent with the clinical results.On day 3,the patient was alert and showed good limb movements.CONCLUSION In patients with peripheral VA-ECMO,cerebral perfusion confirmed by CTP and CTA may lead to false cerebral infarction.
文摘BACKGROUND Extracorporeal shock wave therapy(ESWT)is increasingly being recognized as an advantageous alternative for treating non-union due to its efficacy and minimal associated complications.Non-union following Bernese periacetabular osteotomy(PAO)is particularly challenging,with a reported 55%delayed union and 8%non-union.Herein,we highlight a unique case of ischial non-union post-PAO treated successfully with a structured ESWT regimen.CASE SUMMARY A 50-year-old patient,diagnosed with left ischial non-union following the PAO,underwent six cycles of ESWT treatment across ten months.Each cycle,spaced four weeks apart,consisted of five consecutive ESWT sessions without anesthesia.Regular X-ray follow-ups showed progressive disappearance of the fracture line and fracture union.The patient ultimately achieved a satisfactory asymptomatic recovery and bone union.CONCLUSION The results from this case suggest that this ESWT regimen can be a promising non-invasive treatment strategy for non-union following PAO.
文摘BACKGROUND Due to the lack of published literature about treatment of refractory hepatopulmonary syndrome(HPS)after liver transplant(LT),this case adds information and experience on this issue along with a treatment with positive outcomes.HPS is a complication of end-stage liver disease,with a 10%-30%incidence in cirrhotic patients.LT can reverse the physiopathology of this process and restore normal oxygenation.However,in some cases,refractory hypoxemia persists,and extracorporeal membrane oxygenation(ECMO)can be used as a rescue therapy with good results.CASE SUMMARY A 59-year-old patient with alcohol-related liver cirrhosis and portal hypertension was included in the LT waiting list for HPS.He had good liver function(Model for End-Stage Liver Disease score 12,Child-Pugh class B7).He had pulmonary fibrosis and a mild restrictive respiratory pattern with a basal oxygen saturation of 82%.The macroaggregated albumin test result was>30.Spirometry demonstrated a forced expiratory volume in one second(FEV1)of 78%,forced vital capacity(FVC)of 74%,FEV1/FVC ratio of 81%,diffusion capacity for carbon monoxide of 42%,and carbon monoxide transfer coefficient of 57%.He required domiciliary oxygen at 2 L/min(16 h/d).The patient was admitted to the intensive care unit(ICU)and extubated in the first 24 h,needing high-flow therapy and non-invasive ventilation and inhaled nitric oxide afterwards.Reintubation was needed after 72 h.Due to the non-response to supportive therapies,installation of ECMO was decided with progressive recovery after 9 d.Extubation was possible on the tenth day,maintaining a high-flow nasal cannula and de-escalating to conventional oxygen therapy after 48 h.He was discharged from ICU on postoperative day(POD)20 with a 90%-92%oxygen saturation.Steroid recycling was needed twice for acute rejection.The patient was discharged from hospital on POD 27 with no symptoms,with an 89%-90%oxygen saturation.CONCLUSION Due to the favorable results observed,ECMO could become the central axis of treatment of HPS and refractory hypoxemia after LT.
文摘Objectives: To assess the efficiency in terms of cost-effectiveness (CE) of oral Renalof® treatment versus extracorporeal shockwave lithotripsy (ESWL) in the treatment of kidney stones ≤ 1 cm in Nicaragua. Methods: A cost-effectiveness economic evaluation was carried out based on the results obtained in the randomised, prospective, observational, single-blind, prospective, phase 2 clinical trial. Cost-effectiveness and the incremental cost-effectiveness ratio (ICER) were calculated. Economic data were obtained from the Economics Department of Clínica Senior in Managua, Nicaragua. The monetary cost was expressed in US dollars (USD). Results: Treatment with Renalof® yielded a CE of $1,323.08/% remission, while ESWL was $9,498.54/% remission. The ICER shows that, in order to achieve a high percentage of kidney stone remission with ESWL, an extra $4,734.70 per patient must be invested. Conclusions: The use of Renalof® is shown to be a more cost-effective option than ESWL. It is recommended for the treatment of kidney stones ≤ 1 cm in size.
文摘Extracorporeal organ support(ECOS)has made remarkable progress over the last few years.Renal replacement therapy,introduced a few decades ago,was the first available application of ECOS.The subsequent evolution of ECOS enabled the enhanced support to many other organs,including the heart[veno-arterial extracorporeal membrane oxygenation(ECMO),slow continuous ultrafiltration],the lungs(veno-venous ECMO,extracorporeal carbon dioxide removal),and the liver(blood purification techniques for the detoxification of liver toxins).Moreover,additional indications of these methods,including the suppression of excessive inflammatory response occurring in severe disorders such as sepsis,coronavirus disease 2019,pancreatitis,and trauma(blood purification techniques for the removal of exotoxins,endotoxins,or cytokines),have arisen.Multiple organ support therapy is crucial since a vast majority of critically ill patients present not with a single but with multiple organ failure(MOF),whereas,traditional therapeutic approaches(mechanical ventilation for acute respiratory failure,antibiotics for sepsis,and inotropes for cardiac dysfunction)have reached the maximum efficacy and cannot be improved further.However,several issues remain to be clarified,such as the complexity and cost of ECOS systems,standardization of indications,therapeutic protocols and initiation time,choice of the patients who will benefit most from these interventions,while evidence from randomized controlled trials supporting their use is still limited.Nevertheless,these methods are currently a part of routine clinical practice in intensive care units.This editorial presents the past,present,and future considerations,as well as perspectives regarding these therapies.Our better understanding of these methods,the pathophysiology of MOF,the crosstalk between native organs resulting in MOF,and the crosstalk between native organs and artificial organ support systems when applied sequentially or simultaneously,will lead to the multiplication of their effects and the minimization of complications arising from their use.
文摘Objective: To investigate the effect of extracorporeal diaphragmatic pacing combined with noninvasive ventilators on the respiratory function and prognosis of chronic obstructive pulmonary disease (COPD) patients. Methods: A total of 50 COPD patients were selected between January 2023 to December 2023 and randomly grouped into an observation group and a control group, with 25 cases. The observation group was given extracorporeal diaphragm pacing combined with a noninvasive ventilator, while the control group was given a conventional treatment mode. After the treatment, the results of each index in the two groups were compared. Results: Compared with the diaphragm function indexes of the two groups, the data of the observation group were more dominant (P < 0.05). The rehospitalization rate of the observation group was lower than that of the control group (P < 0.05). The COPD assessment test (CAT) and mMRC (Modified Medical Research Council) Dyspnoea scale scores after treatment between the two groups were significantly different (P < 0.05). Compared with the control group, the lung function indexes of the observation group were more dominant (P < 0.05). Conclusion: Extracorporeal diaphragmatic pacing combined with a noninvasive ventilator promoted the improvement of the patient’s prognosis and improved their respiratory function.
文摘Objective: To analyze the effect of combined extracorporeal shock wave and rehabilitation training treatment in patients with muscle articulation chronic pain (MACP). Methods: Ninety-seven MACP patients admitted to our hospital from September 2021 to September 2023 were randomly selected and were divided into Group A (control group, 46 cases, rehabilitation training treatment) and Group B (observation group, 51 cases, extracorporeal shock wave with rehabilitation training treatment), and outcomes of the two groups were compared. Results: The treatment efficiency, post-treatment clinical indexes (upper and lower limb function scores, activities of daily living (ADL) scores, visual analog scale (VAS) scores), and short-form 36 (SF-36) scores of Group B were better than those of Group A (P < 0.05). Conclusion: Combined extracorporeal shock wave and rehabilitation training treatment for MACP patients improved their limb function, daily activities, quality of life, and reduced pain.
文摘Objective:To evaluate the application effect of predictive nursing on patients undergoing heart valve surgery with extracorporeal circulation(ECC).Methods:92 ECC patients admitted to the hospital between July 2021 and July 2023 were selected and grouped by random number table method;the observation group practiced predictive nursing,while the reference group practiced conventional nursing.The cardiopulmonary rehabilitation and other indexes were compared between the groups.Results:The postoperative rehabilitation time of the observation group was shorter than that of the reference group,the treatment compliance was higher than that of the reference group,the cardiopulmonary function indexes were all better than that of the reference group,and the complication rate was lower than that of the reference group(P<0.05).Conclusion:The implementation of predictive nursing for ECC patients can promote postoperative rehabilitation,improve patients’treatment compliance,and enhance the cardiopulmonary rehabilitation effect,and nursing safety is high.
文摘Objective: To compare the effects of extracorporeal membrane oxygenation (ECMO) and routine mechanical ventilation on mortality and the risk of associated adverse events in patients with severe viral pneumonia. Methods: PubMed, the Cochrane Library, Embase, Web of Science, and other databases were searched to collect case-control or cohort studies on prognoses associated with ECMO treatment for viral pneumonia. Search terms included extracorporeal membrane oxygenation, ECMO, viral pneumonia, COVID-19, influenza, MERS, and others. According to the PICOS principle, two evaluators independently screened the literature, extracted the data, cross-checked the data, and extracted the data again. Two researchers evaluated the risk of bias in the included studies according to the Newcastle-Ottawa Scale (NOS) and cross-checked the results. Meta-analysis was performed using RevMan 5.3 software. Results: Nine studies were included for analysis, encompassing a total of 4,330 patients, which were categorized into ECMO and CMV groups. There were no significant differences between the two groups in most baseline data;however, the ECMO group had a lower oxygenation index, and some studies reported higher SOFA scores in the ECMO group compared to the CMV group. There was no significant difference in in-hospital mortality between the two groups. The length of ICU stay, total hospital stay, and total mechanical ventilation time were longer in the ECMO group than in the CMV group. In terms of adverse events, there was no significant difference in the occurrence of kidney injury between the two groups. Bleeding events were reported in two studies, with more bleeding events occurring in the ECMO group. According to the subgroup analysis of different virus types, there were no statistical differences in the above aspects among patients with swine flu, novel coronavirus, and MERS. Conclusion: ECMO has a certain degree of positive significance in the treatment of severe viral pneumonia, but there is no significant difference in the treatment outcome of ECMO across different epidemic periods. The timing of ECMO treatment, patient management, and withdrawal evaluation still need further research.
文摘Clinically,it is highly challenging to promote recovery in patients with acute liver failure(ALF)and acute-on-chronic liver failure(ACLF).Despite recent advances in understanding the underlying mechanisms of ALF and ACLF,standard medical therapy remains the primary therapeutic approach.Liver transplantation(LT)is considered the last option,and in several cases,it is the only intervention that can be lifesaving.Unfortunately,this intervention is limited by organ donation shortage or exclusion criteria such that not all patients in need can receive a transplant.Another option is to restore impaired liver function with artificial extracorporeal blood purification systems.The first such systems were developed at the end of the 20th century,providing solutions as bridging therapy,either for liver recovery or LT.They enhance the elimination of metabolites and substances that accumulate due to compromised liver function.In addition,they aid in clearance of molecules released during acute liver decompensation,which can initiate an excessive inflammatory response in these patients causing hepatic encephalopathy,multiple-organ failure,and other complications of liver failure.As compared to renal replacement therapies,we have been unsuccessful in using artificial extracorporeal blood purification systems to completely replace liver function despite the outstanding technological evolution of these systems.Extracting middle to high-molecular-weight and hydrophobic/protein-bound molecules remains extremely challenging.The majority of the currently available systems include a combination of methods that cleanse different ranges and types of molecules and toxins.Furthermore,conventional methods such as plasma exchange are being re-evaluated,and novel adsorption filters are increasingly being used for liver indications.These strategies are very promising for the treatment of liver failure.Nevertheless,the best method,system,or device has not been developed yet,and its probability of getting developed in the near future is also low.Furthermore,little is known about the effects of liver support systems on the overall and transplant-free survival of these patients,and further investigation using randomized controlled trials and meta-analyses is needed.This review presents the most popular extracorporeal blood purification techniques for liver replacement therapy.It focuses on general principles of their function,and on evidence regarding their effectiveness in detoxification and in supporting patients with ALF and ACLF.In addition,we have outlined the basic advantages and disadvantages of each system.

文摘BACKGROUND:The ion shift index(ISI) as a prognostic indicator that can show the severity of hypoxic-ischemic injury.We aimed to evaluate the performance of the ISI in predicting unfavorable neurological outcomes at hospital discharge in cardiac arrest(CA) patients following extracorporeal cardiopulmonary resuscitation(ECPR) and to compare its performance to other prognostic predictors.METHODS:This was a retrospective observational study including adult CA patients treated with ECPR between January 2018 and December 2022 in a tertiary hospital.Data regarding clinical characteristics and laboratory parameters were collected from medical records.The ISI was determined based on the first available serum electrolyte levels after ECPR.The primary outcome was unfavorable neurological status at hospital discharge,defined as Cerebral Performance Categories 3–5.Comparisons of the characteristics between the two groups were made using the χ2 test for categorical variables and the t-test or non-parametric Mann-Whitney U-test for continuous variables,as appropriate.Correlation analysis was performed using Spearman’s rank correlation coeficient.A two-tailed P-value <0.05 was considered statistically significant.RESULTS:Among the 122 patients involved,46(37.7%) had out-of-hospital CA,and 88 had unfavorable neurological outcomes.The ISI was significantly higher in the unfavorable outcome group than in the favorable outcome group(3.74 [3.15–4.57] vs.2.69 [2.51–3.07],P<0.001).A higher ISI level was independently related to unfavorable outcome(odds ratio=6.529,95% confidence interval 2.239–19.044,P=0.001).An ISI level >3.12 predicted unfavorable outcomes with a sensitivity and specificity of 74.6% and 85.2%,respectively(P<0.001).The prognostic performance of ISI(area under the curve [AUC]=0.887) was similar to that of other predictors,such as gray-to-white matter ratio(AUC=0.850,P=0.433) and neuronspecific enolase(AUC=0.925,P=0.394).CONCLUSION:ISI may be used as a prognostic biomarker to predict neurological outcomes in CA patients following ECPR.
文摘BACKGROUND Despite various therapies to treat sepsis,it is one of the leading causes of mortality in the intensive care unit patients globally.Knowledge about the pathophysiology of sepsis has sparked interest in extracorporeal therapies(ECT)which are intended to balance the dysregulation of the immune system by removing excessive levels of inflammatory mediators.AIM To review recent data on the use of ECT in sepsis and to assess their effects on various inflammatory and clinical outcomes.METHODS In this review,an extensive English literature search was conducted from the last two decades to identify the use of ECT in sepsis.A total of 68 articles from peer-reviewed and indexed journals were selected excluding publications with only abstracts.RESULTS Results showed that ECT techniques such as high-volume hemofiltration,coupled plasma adsorption/filtration,resin or polymer adsorbers,and CytoSorb®are emerging as adjunct therapies to improve hemodynamic stability in sepsis.CytoSorb®has the most published data in regard to the use in the field of septic shock with reports on improved survival rates and lowered sequential organ failure assessment scores,lactate levels,total leucocyte count,platelet count,interleukin-IL-6,IL-10,and TNF levels.CONCLUSION Clinical acceptance of ECT in sepsis and septic shock is currently still limited due to a lack of large random clinical trials.In addition to patient-tailored therapies,future research developments with therapies targeting the cellular level of the immune response are expected.
