文摘BACKGROUND:Remimazolam is a novel ultra-short-acting sedative,but its safety and adverse events(AEs)in high-risk patients in the intensive care unit(ICU)setting remain unknown.METHODS:This was a single-center,retrospective study that compared remimazolam to propofol and midazolam in patients undergoing upper gastrointestinal endoscopy.The primary outcome was the incidence of treatment-related AEs.The secondary outcomes were the time to extubation,the length of ICU stay,and the average cost of sedative per case.RESULTS:Of the 88 patients analyzed,47 were treated with remimazolam(mean dose,7.90±4.84mg),and 41 were treated with propofol(21.19±17.98 mg)or midazolam(3.08±2.17 mg).There was no statistically significant difference in the average duration of the endoscopic procedure(35.89±13.37 min vs.44.51±21.68 min,P=0.133)or the time to extubation(15.00±9.75 h vs.20.59±18.71 h,P=0.211)in the remimazolam group(group I)compared to the propofol or midazolam group(group II).ICU stays(5.40±2.93 d vs.4.63±3.31 d,P=0.072)and treatment-related AEs(48.61%vs.51.38%,P=0.056)were similar between groups.The average cost of sedative per case was significantly lower in the group I than in the group II(RMB 16.07±10.58 yuan vs.RMB 24.37±15.46 yuan,P=0.016).CONCLUSION:Remimazolam-based sedation was noninferior to the classic sedatives and had lower average cost per case,indicating that it may be used as a promising sedative for high-risk patients during endoscopic procedures in the ICU setting.
文摘BACKGROUND Chronic obstructive pulmonary disease(COPD)is associated with high morbidity and mortality rates worldwide.Older patients have a degenerative cardiopulmonary function,weak compensatory capacity,and poor surgical tolerance.Therefore,the mode of anesthesia must be optimized.Remimazolam is a new ultrashort-acting benzodiazepine with a rapid onset of action,rapid metabolism,and mild effects on pulmonary circulation.Remimazolam sedation combined with an epidural block has not been reported in hypertensive older adults with severe COPD and inguinal mass resection.CASE SUMMARY We report the case of a 73-year-old man with hypertension and severe COPD,who underwent resection of an enlarged inguinal mass that he had noticed more than 7 mo before presentation.The patient presented with a“right inguinal mass”and was recommended to undergo an enlarged inguinal mass resection.Surgery was relatively challenging,due to the large mass(13 cm×8 cm×7 cm),hard texture,and poor mobility.Considering the advanced age of the patient,gradeⅢhypertension,and severe COPD,we administered remimazolam combined with an epidural block for anesthesia to ensure perioperative safety and careful consideration.The anesthetic effect was precise;the procedure was performed smoothly without any complications,and the patient was successfully anesthetized.However,anesthetic management in such cases has not yet been reported by previous studies.CONCLUSION Remimazolam sedation combined with an epidural block is safe and effective in older patients with hypertension and severe COPD.
文摘BACKGROUND Transversus abdominis plane block(TAPB)is a block of the abdominal afferent nerve fibers between the internal oblique muscle and the transverse abdominal muscle achieved with local anesthetics.It can effectively block the conduction of the anterior nerve of the abdominal wall and exert a good analgesic effect.However,the effect of combining the block with remimazolam on anesthesia in patients undergoing gastrointestinal tumor surgery is still unclear.AIM To examine the effects of combining TAPB with remimazolam on the stress response and postoperative recovery of gastrointestinal tumor surgery patients.METHODS A retrospective analysis was conducted on the clinical data of 102 individuals diagnosed with gastrointestinal malignancies who underwent laparoscopic surgery under general anesthesia between April 2020 and June 2023.The patients were categorized into a control group(n=51),receiving remimazolam for general anesthesia,and an observation group(n=51),receiving TAPB combined with remimazolam for general anesthesia.A comparison was made between both groups in terms of hemodynamic parameters,stress markers,pain levels,recovery quality,analgesic effects,and adverse reactions during the perioperative period.RESULTS The observation group had significantly higher heart rates at time points 1 min after induction and upon leaving the operating room than the control group(P<0.05).The mean arterial pressure at time point T1 in the observation group was significantly higher than that in the control group(P<0.05).Five minutes after extubation,the levels of the hormones adrenaline and noradrenaline in the observation group were considerably lower than those in the control group(P<0.05).At 12 h,24 h,and 48 h following surgery,the visual analog scale scores of the observation group were considerably lower than those of the control group(P<0.05).The observation group had shorter awakening and extubation times and lower Riker sedation-agitation scale scores than the control group(P<0.05).The observation group exhibited considerably fewer effective pump presses,lower fentanyl dosages,and lower incidences of rescue analgesia within 24 h following surgery than the control group(P<0.05).CONCLUSION The application effect of TAPB combined with remimazolam general anesthesia in anesthesia of patients undergoing gastrointestinal tumor surgery is good,which is helpful to promote faster recovery after operation.
