There are non-invasive prenatal diagnosis procedures and invasive prenatal diagnosis procedures. The invasive prenatal diagnosis procedures are CVS (chorionic villus sampling) and amniocentesis. The American College of Obstetricians and Gynecologists states that invasive diagnostic testing should be available to all women, regardless of age or risk. Objective: To determine the indications, outcome and results of diagnostic invasive prenatal procedures. Study setting: The obstetrics and Gynecology Department in Salmaniya Medical Complex in Kingdom of Bahrain. Study design: Retrospective descriptive study. Study subjects and Methods: This retrospective descriptive study was conducted on 175 pregnant women who underwent invasive prenatal procedures (CVS and amniocentesis) between January 2013 and December 2018 at SMC in Kingdom of Bahrain. All medical records of the participants were reviewed and entered the study. According to the implemented procedures, medical records were categorized into two chorionic villus sampling (CVS) and amniocentesis groups. The study subject will include indications of the procedures which are advanced maternal age, hematological disorders, genetic disorders, metabolic disorders, abnormal structural findings in fetal ultrasound and previous child with aneuploidy. In addition, the study will address the complications, outcome and results of procedures. Results: About half of our indications of the procedures were due to hematological disorders (47.6%) followed by abnormal structural findings in fetal ultrasound (30.1%) then genetic disorders (15.7%), metabolic disorders (4.8%) and advanced maternal age (1.8%). Regarding complications of the procedure;threatened miscarriage or loss of pregnancy within 3 weeks was (2.3%), amniotic fluid leakage (0.7%), abdominal cramps (0.7%) and Insufficient or contaminated sample (6.2%). Regarding outcome of the pregnancy, our results showed that the loss of pregnancy was (4.8%), intrauterine fetal death or still birth was (13.9%), live birth was (63.9%), preterm delivery was (7.8%), preterm premature rupture of membrane (PPROM) was (1.8%), limbs reduction was (0.0%). Termination of pregnancy outside the country was (7.8%) of chorionic villus sampling and amniocentesis. Conclusion: CVS and amniocentesis are useful outpatient procedures to detect diagnosis or to assess whether a patient is at increased risk of having an affected fetus and that will minimize the psychological impact on the patient and to provide a proper antenatal care to the pregnant women by her obstetrician and follow up to the baby by pediatrician. In this study it was observed that most of the patients who underwent the procedure were couples either carrier or affected to sickle cell disease or Beta thalassemia.展开更多

Purpose: This scoping review aimed to map the existing literature related to recent institution-provided educational programs for invasive procedures involving clinical nurses. This study seeks to understand the contents of educational programs and the methods for assessing educational effects. Methods: This scoping review was completed using the following four databases: PubMed (MEDLINE), Embase, Cochrane Library, and Emcare for the period 2000-2022. We included studies that used all forms of educational approaches (e.g., didactic lectures, hands-on training, or on-the-job training). This scoping review considered peer-reviewed publications published in English using quantitative, qualitative, or mixed approaches. A total of 83 studies underwent in the final analysis. Results and Conclusion: A combination of didactic lectures and hands-on training was provided as an educational program in most studies. Contrary to our prediction, educational interventions with advanced technologies such as VR are extremely rare, suggesting that the effectiveness of advanced technologies in learning invasive procedures should be examined to facilitate and retain educational effects more efficiently in future studies. Regarding the assessment of educational effects, nurses’ cognitive (i.e., theoretical knowledge about procedures), psychomotor (i.e., implementing procedures), and psychological aspects (e.g., confidence and self-efficacy in procedures) were evaluated using questionnaires and observational methods. While most studies used a one-group pretest-posttest design, the ratio of randomized controlled trials (RCT) was relatively low. Thus, an RCT design should be introduced in future studies to test the validity of the developed educational program more accurately.展开更多

METHODS： We reviewed the charts of 195 patients with cirrhosis who underwent surgery at two teaching hospitals over a five-year period. The combined endpoint of death or hepatic decompensation was considered to be the primary endpoint. RESULTS： Patients who reached the endpoint had a higher MELD score, a higher CTP score and were more likely to have undergone an urgent procedure. Among patients undergoing elective surgical procedures, no statistically significant difference was noted in the mean MELD （12.8 ＋ 3.9 vs 12.6 ＋ 4.7, P = 0.9） or in the mean CTP （7.6 ± 1.2 vs 7.7 ± 1.7, P = 0.8） between patients who reached the endpoint and those who did not. Both mean scores were higher in the patients reaching the endpoint in the case of urgent procedures （MELD： 22.4 ± 8.7 vs 15.2 ± 6.4, P = 0.0007; CTP： 9.9 ± 1.8 vs 8.5 ± 1.8, P = 0.008）. The performances of the MELD and CTP scores in predicting the outcome of urgent surgery were only fair, without a significant difference between them （AUC = 0.755 ± 0.066 for MELD vs AUC = 0.696 ± 0.070 for CTP, P = 0.3）. CONCLUSION： The CTP and MELD scores performed equally, but only fairly in predicting the outcome of urgent surgical procedures. Larger studies are needed to better define the factors capable of predicting the outcome of elective surgical procedures in patients with cirrhosis.equally, but only fairly in predicting the outcome of urgent surgical procedures.

Post-ERCP pancreatitis is an important concern, and prophylaxis, cannulation and other related technical procedures have been well documented by endoscopists. In addition, medical radiation exposure is of great concern in the general population because of its rapidly increasing frequency and its potential carcinogenic effects. International organizations and radiological societies have established diagnostic reference levels, which guide proper radiation use and serve as global standards for all procedures that use ionizing radiation. However, data on gastrointestinal fluoroscopic procedures are still lacking because the demand for these procedures has recently increased. In this review, we present the current status of quality indicators for ERCP and the methods for measuring radiation exposure in the clinical setting as the next quality indicator for ERCP. To reduce radiation exposure, knowledge of its adverse effects and the procedures for proper measurement and protection are essential. Additionally, further studies on the factors that affect radiation exposure, exposure management and diagnostic reference levels are necessary. Then, we can discuss how to manage medical radiation use inthese complex fluoroscopic procedures. This knowledge will help us to protect not only patients but also endoscopists and medical staff in the fluoroscopy unit.展开更多

An original questionnaire about the current status and awareness of psychological preparation for children in hospitals was distributed by mail to nurses’ working on Japanese pediatric wards in 2010. The same questionnaire, translated into German, was distributed to nurses working on German pediatric wards via the internet in 2010. A large majority of respondents strongly agreed that children have a right to informed consent. German nurses expressed a longer-term viewpoint on the effects of preparation than Japanese nurses. Japanese nurses recognized a greater need for improvement in their duties than German nurses. The results suggest that we should consider our own country’s nursing practices and need for improvement, but also learn from studies of other countries to address each culture and medical situation appropriately.展开更多

Kangaroo Care (chest-to-chest, skin-to-skin position of infant on mother) effectively reduces pain of single procedures, but its effect on pain from clustered procedures is not known. Aim: The aim was to test Kangaroo Care’s effect on pain in one term infant who received clustered painful procedures while determining feasibility of the Kangaroo Care intervention. Design, Setting, and Participant: A case study design was used with one healthy term newborn who received two heel sticks and one injection in one session in the mother’s postpartum room. Method: Heart rate and oxygen saturation (recorded from Massimo Pulse Oximeter every 30 seconds), crying time (total seconds of crying on videotape) and behavioral state (using Anderson Behavioral State Scoring system every 30 seconds) were measured before (5 minutes), during (10.5 minutes) and after (30 minutes) the three clustered painful procedures in a newborn who was in Kangaroo Care during all observations. One staff nurse administered the clustered procedures. Results: Heart rate increased sequentially with each heelstick, oxygen saturation remained unchanged, sleep predominated, and crying was minimal throughout the procedures. Conclusion: Kangaroo Care appeared to reduce pain from clustered painful procedures and can be further tested.展开更多

The purpose of this work was to determine the causes of cancellation of elective surgical operations in a major pediatric surgery department in Senegal. Patients and methods: It was a prospective and descriptive study of 278 patients scheduled during a period of 13 weeks. The study took place between April 3<sup>rd</sup>, 2017, and January 31<sup>st</sup>, 2018. Mean age was 2.9 years with extremes of 3 days and 15 years. The age group of 29 days to 30 months was the most represented (62.2%). Sex ratio was 1.41. Causes of cancellation were categorized into administrative and organizational causes, patient-related causes and staff-related causes. Results: Cancellation rate was 29.4%. Patient-related causes were most common (51.2%). Upper Respiratory tract infection (URTI) was commonest reason within this category (57.5%). Organizational causes (28.1%) came second and were mainly represented by the unavailability of the operating room (60.8%) related to breakdowns of anesthesia equipment. Finally, staff-related causes (20.7%) were due for most to the unavailability of the anesthesiologist (12 cases/17). Conclusion: Majority of causes that led to cancellation of elective surgical operations in our Pediatric surgery department are related to intercurrent illnesses affecting the patient, in particular URTI.展开更多

文摘Endoscopic retrograde cholangiopancreatography(ERCP) is one of the most frequently used image-guided procedures in gastrointestinal endoscopy. Post-ERCP pancreatitis is an important concern, and prophylaxis, cannulation and other related technical procedures have been well documented by endoscopists. In addition, medical radiation exposure is of great concern in the general population because of its rapidly increasing frequency and its potential carcinogenic effects. International organizations and radiological societies have established diagnostic reference levels, which guide proper radiation use and serve as global standards for all procedures that use ionizing radiation. However, data on gastrointestinal fluoroscopic procedures are still lacking because the demand for these procedures has recently increased. In this review, we present the current status of quality indicators for ERCP and the methods for measuring radiation exposure in the clinical setting as the next quality indicator for ERCP. To reduce radiation exposure, knowledge of its adverse effects and the procedures for proper measurement and protection are essential. Additionally, further studies on the factors that affect radiation exposure, exposure management and diagnostic reference levels are necessary. Then, we can discuss how to manage medical radiation use inthese complex fluoroscopic procedures. This knowledge will help us to protect not only patients but also endoscopists and medical staff in the fluoroscopy unit.

文摘BACKGROUND Chronic liver disease(CLD)related thrombocytopenia increases the risk of bleeding and poor prognosis.Many liver disease patients require invasive procedures or surgeries,such as liver biopsy or endoscopic variceal ligation,and most of them have lower platelet counts,which could aggravate the risk of bleeding due to liver dysfunction and coagulation disorders.Unfortunately,there is no defined treatment modality for CLD-induced thrombocytopenia.Recombinant human thrombopoietin(rhTPO)is commonly used to treat primary immune thrombocytopenic purpura and thrombocytopenia caused by solid tumor chemotherapy;however,there are few reports on the use of rhTPO in the treatment of CLD-related thrombocytopenia.AIM To evaluate the efficacy of rhTPO in the treatment of patients with CLDassociated thrombocytopenia undergoing invasive procedures.METHODS All analyses were based on the retrospective collection of clinical data of patients with CLD who were treated in the Department of Infectious Diseases at The First Affiliated Hospital of Soochow University between June 2020 and December 2021.Fifty-nine male and 41 female patients with liver disease were enrolled in this study to assess the changes in platelet counts and parameters before and after the use of rhTPO for thrombocytopenia.Adverse events related to treatment,such as bleeding,thrombosis,and disseminated intravascular coagulation,were also investigated.RESULTS Among the enrolled patients,78(78%)showed a platelet count increase after rhTPO use,while 22(22%)showed no significant change in platelet count.The mean platelet count after rhTPO treatment in all patients was 101.53±81.81×10^(9)/L,which was significantly improved compared to that at baseline(42.88±16.72×10^(9)/L),and this difference was statistically significant(P<0.001).In addition,patients were further divided into three subgroups according to their baseline platelet counts(<30×10^(9)/L,30-50×10^(9)/L,>50×10^(9)/L).Subgroup analyses showed that the median platelet counts after treatment were significantly higher(P<0.001,all).Ninety(90%)patients did not require platelet transfusion partially due to an increase in platelet count after treatment with rhTPO.No serious adverse events related to rhTPO treatment were observed.Overall,rhTPO demonstrated good clinical efficacy for treating CLD-associated thrombocytopenia.CONCLUSION rhTPO can improve platelet count,reduce the risk of bleeding,and decrease the platelet transfusion rate,which may promote the safety of invasive procedures and improve overall survival of patients with CLD.
文摘Some research results are given in this paper about burnthrough and hydrogen cracking with a flowing chamber and a loop. Many factors including plate thickness, running rate, heat input and so forth have been studied.

文摘BACKGROUND In endovascular procedures including total percutaneous endovascular aneurysm repair(pEVAR),percutaneous access through the common femoral artery is most commonly performed.Access-site bleeding is a major concern in percutaneous techniques.Herein,we present a case of successful control of continuous oozing using a vascular closure device(VCD)and the application of Surgicel(Johnson&Johnson,United States)over the access tract.CASE SUMMARY An 82-year-old man presented with an unruptured abdominal aortic aneurysm measuring 83 mm×75 mm.The patient had a medical history of atrial fibrillation and was receiving rivaroxaban(15 mg/d).Routine pEVAR was performed using the preclose technique with ProGlide(Abbott,Santa Clara,CA,United States).Significant amount of bleeding was observed at the end of the procedure after the deployment of the closure device at the access site.A sheet of Surgicel was applied to the suture thread using a surgical needle.Surgicel was applied to the surface of the artery along the access tract using a pusher,and hemostasis was immediately attained.CONCLUSION This simple technique is an excellent adjunct to control residual bleeding from the access site following VCD use.
文摘The present study aimed to clarify the current status and awareness of psychological preparation for children undergoing medical procedures in pediatric nursing in Japan as compared with that in Germany. An original questionnaire about the current status and awareness of psychological preparation for children in hospitals was distributed by mail to nurses’ working on Japanese pediatric wards in 2010. The same questionnaire, translated into German, was distributed to nurses working on German pediatric wards via the internet in 2010. A large majority of respondents strongly agreed that children have a right to informed consent. German nurses expressed a longer-term viewpoint on the effects of preparation than Japanese nurses. Japanese nurses recognized a greater need for improvement in their duties than German nurses. The results suggest that we should consider our own country’s nursing practices and need for improvement, but also learn from studies of other countries to address each culture and medical situation appropriately.
文摘Traditionally performed by a small group of highly trained specialists,bedside sonographic procedures involving the musculoskeletal system are often delayed despite the critical need for timely diagnosis and treatment.Due to this limitation,a need evolved for more portability and accessibility to allow performance of emergent musculoskeletal procedures by adequately trained non-radiology personnel.The emergence of ultrasound-assisted bedside techniques and increased availability of portable sonography provided such an opportunity in select clinical scenarios.This review summarizes the current literature describing common ultrasound-based musculoskeletal procedures.In-depth discussion of each ultrasound procedure including pertinent technical details,indications and contraindications is provided.Despite the limited amount of prospective,randomized data in this area,a substantial body of observational and retrospective evidence suggests potential benefits from the use of musculoskeletal bedside sonography.

文摘Background: Pain management for term newborns undergoing clustered painful procedures has not been tested. Kangaroo Care (chest-to-chest, skin-to-skin position of infant on mother) effectively reduces pain of single procedures, but its effect on pain from clustered procedures is not known. Aim: The aim was to test Kangaroo Care’s effect on pain in one term infant who received clustered painful procedures while determining feasibility of the Kangaroo Care intervention. Design, Setting, and Participant: A case study design was used with one healthy term newborn who received two heel sticks and one injection in one session in the mother’s postpartum room. Method: Heart rate and oxygen saturation (recorded from Massimo Pulse Oximeter every 30 seconds), crying time (total seconds of crying on videotape) and behavioral state (using Anderson Behavioral State Scoring system every 30 seconds) were measured before (5 minutes), during (10.5 minutes) and after (30 minutes) the three clustered painful procedures in a newborn who was in Kangaroo Care during all observations. One staff nurse administered the clustered procedures. Results: Heart rate increased sequentially with each heelstick, oxygen saturation remained unchanged, sleep predominated, and crying was minimal throughout the procedures. Conclusion: Kangaroo Care appeared to reduce pain from clustered painful procedures and can be further tested.

文摘Introduction: Cancellation of surgical operation is a surgical operation registered in the official schedule the day before or added to the list after and not carried out on the operating day. The purpose of this work was to determine the causes of cancellation of elective surgical operations in a major pediatric surgery department in Senegal. Patients and methods: It was a prospective and descriptive study of 278 patients scheduled during a period of 13 weeks. The study took place between April 3<sup>rd</sup>, 2017, and January 31<sup>st</sup>, 2018. Mean age was 2.9 years with extremes of 3 days and 15 years. The age group of 29 days to 30 months was the most represented (62.2%). Sex ratio was 1.41. Causes of cancellation were categorized into administrative and organizational causes, patient-related causes and staff-related causes. Results: Cancellation rate was 29.4%. Patient-related causes were most common (51.2%). Upper Respiratory tract infection (URTI) was commonest reason within this category (57.5%). Organizational causes (28.1%) came second and were mainly represented by the unavailability of the operating room (60.8%) related to breakdowns of anesthesia equipment. Finally, staff-related causes (20.7%) were due for most to the unavailability of the anesthesiologist (12 cases/17). Conclusion: Majority of causes that led to cancellation of elective surgical operations in our Pediatric surgery department are related to intercurrent illnesses affecting the patient, in particular URTI.
文摘Background A virtual system that simulates the complete process of orthodontic bracket placement can be used for pre-clinical skill training to help students gain confidence by performing the required tasks on a virtual patient.Methods The hardware for the virtual simulation system is built using two force feedback devices to support bi-manual force feedback operation.A 3D mouse is used to adjust the position of the virtual patient.A multi-threaded computational methodology is adopted to satisfy the requirements of the frame rate.The computation threads mainly consist of the haptic thread running at a frequency of>1000Hz and the graphic thread at>30Hz.The graphic thread allows the graphics engine to effectively display the visual effects of biofilm removal and acid erosion through texture mapping.Using the haptic thread,the physics engine adopts the hierarchy octree collision-detection algorithm to simulate the multi-point and multi-region interaction between the tools and the virtual environment.Its high efficiency guarantees that the time cost can be controlled within 1 ms.The physics engine also performs collision detection between the tools and particles,making it possible to simulate paint and removal of colloids.The surface-contact constraints are defined in the system;this ensures that the bracket will not divorce from or embed into the tooth during the adjustment of the bracket.Therefore,the simulated adjustment is more realistic and natural.Results A virtual system to simulate the complete process of orthodontic bracket bonding was developed.In addition to bracket bonding and adjustment,the system simulates the necessary auxiliary steps such as smearing,acid etching,and washing.Furthermore,the system supports personalized case training.Conclusions The system provides a new method for students to practice orthodontic skills.

文摘Anticoagulation is imperative to reduce the incidence of thrombotic complications in patients undergoing percutaneous interventional cardiovascular procedures;however,this is at the expense of increased risk of bleeding.The optimal anticoagulation strategy for these procedures remains unclear.Unfractionated heparin is the most commonly used anticoagulant during interventional procedures,but has several limitations,such as relatively high incidence of bleeding events,occurrence of heparin-induced thrombocytopenia,and a paradoxical thrombotic effect.Contemporary studies have demonstrated that bivalirudin decreases the occurrence of bleeding complications,but potentially increases the risk of acute stent thrombosis.This review discusses the pharmacology of bivalirudin and its current clinical application in patients undergoing percutaneous coronary intervention and transcatheter aortic valve replacement procedures.
文摘Objective:To investigate the changes in elective private urological procedures in Australia during the coronavirus disease 2019 pandemic.Methods:Data were extracted from publicly available datasets from Medicare Ben efits Schedule using item nu mbers assig ned to each comm only performed urological interve ntion.These procedures were divided into three groups:Oncological therapeutic,diagnostic,and non-oncological therapeutic procedures.A smoothing model,based on the historic procedure numbers from 2017 to 2019,was used to forecast monthly number of procedures performed in each category between January 2020 and June 2020.These forecasted models were compared with reported figures.Results:A total of 108169 procedures were performed between January 2020 and June 2020 based on the Medicare Ben efits Schedule item nu mbers listed.There was a sign ifica nt reducti on(perce nt-age cha nge)in total procedures performed in April 2020(22.6%,95%con fide nee in terval[CI]:-28.7%to-15.4%)and May 2020(-33.2%,95%CI:-37.5%to 28.3%).There was a significant reduction in oncological therapeutic,non-oncological therapeutic,and diagnostic procedures performed in April 2020 and May 2020(p<0.05).These nu mbers did not in elude procedures performed in public sector.Conclusion:There was a significant reduction in total urological procedures(including diagnostic,oncological,and non-on cological)performed in mon ths of April 2020 and May 2020 during time of federal restrictions.Both public and private healthcare sectors need to be supported in the up-comi ng mon ths to preve nt further delays in treatme nt and poorer clinical outcomes.
