Etomidate versus Remimazolam in Elderly Patients Undergoing Painless Gastroenteroscopy

Objective:To compare the hemodynamic stability of etomidate and remimazolam during painless gastroscopy and evaluate the safety of remimazolam in elderly patients undergoing gastroscopy.Methods:A total of 100 elderly patients aged 65–80 years,with American Society of Anesthesiologists(ASA)physical status I–II,who underwent painless gastrointestinal endoscopy were included in this study.The patients were randomly assigned to receive either 0.2 mg/kg of remimazolam(Group R)or 0.3 mg/kg of etomidate(E group)in combination with alfentanil for anesthesia induction.Results:The mean arterial pressure(MAP)and heart rate(HR)were significantly higher in the E group compared to Group R(P<0.05).Ephedrine was administered more frequently in the Group R(30%)than in the Group E(10%),with a statistically significant difference(P=0.023).The incidence of myoclonus was markedly lower in the Group R(0%)compared to the Group E(60%,P<0.01).Conclusion:During gastroenteroscopy with alfentanil,remimazolam was associated with lower MAP and HR compared to etomidate.Patients receiving remimazolam experienced a higher incidence of post-induction hypotension.Nonetheless,the safety and efficacy of remimazolam were comparable to those of etomidate,supporting its suitability as a sedative for ASA I–II elderly patients undergoing gastrointestinal endoscopy.

Effectiveness of Remimazolam Benzenesulfonate Combined with Alfentanil in Elderly Patients Undergoing Painless Gastroenteroscopy

Objective:To observe the effects of remimazolam benzenesulfonate combined with alfentanil during painless gastroenteroscopy in elderly patients.Methods:This study analyzes patients aged 60–85 years old undergoing painless gastroenteroscopy.A total of 140 patients,examined between February 2023 and February 2024,voluntarily participated and were randomly divided into an experimental group and a control group.The control group received alfentanil combined with propofol for anesthesia,while the experimental group received alfentanil combined with remimazolam benzenesulfonate.The relevant indices of both groups were separately analyzed.Results:Patients in the experimental group had a shorter awakening time,a faster discharge rate(P<0.05),and a shorter examination duration;however,the difference in examination time between the two groups was not statistically significant(P>0.05).Before anesthesia,there was no significant difference in the basic information and vital signs of the two groups(P>0.05).Two minutes after anesthesia,both groups showed a decline in vital signs,but the vital signs of the experimental group remained more stable after the procedure,with the group’s indices showing improvement over the control group(P<0.05).Additionally,the incidence of adverse reactions in the experimental group was lower than in the control group(P<0.05).Conclusion:In painless gastroenteroscopy for elderly patients,anesthesia using a combination of remimazolam benzenesulfonate and alfentanil improves anesthesia effectiveness,hastens patient recovery,enhances the stability of vital signs,and effectively controls adverse reactions,thereby improving patient comfort.

Insights into anesthesia administration for elderly individuals undergoing painless gastroenteroscopy: A bibliometric study

BACKGROUND Administering anesthesia to elderly patients undergoing gastroenteroscopy necessitates careful attention due to age-related physiological changes and an increased risk of complications.AIM To analyze the research trends in anesthesia management for elderly patients undergoing gastroenteroscopy.METHODS We performed a literature search using the Web of Science database to identify articles published between 2004 and 2023.Bibliometric and visual analyses were conducted using CiteSpace,R,and VOSviewer to explore the current research landscape of anesthesia administration in painless gastroenteroscopy for elderly patients and to identify future research directions by examining trends and emerging hotspots in this domain.RESULTS A total of 800 articles were examined,revealing a rising trend in annual pub-lication counts.The United States led with 181 articles,followed by China with 112,collectively contributing over 35%of the studies among the top ten countries.The majority of publications appeared in the United States journals,with the top three being Gastrointestinal Endoscopy[impact factor(IF)=7.7,H-index=26],Digestive Diseases and Sciences(IF=3.1),and Endoscopy(IF=9.3).Six primary research clusters were identified:Obstructive sleep apnea and airway manage-ment,surveillance and risk factors,colorectal cancer examination and treatment,sedation and safety of propofol and midazolam,patient satisfaction,and mortality and complications.These findings underscore the pivotal focus areas in anesthesia for elderly patients undergoing gastroenteroscopy.CONCLUSION A comprehensive understanding of current research trends and hotspots will aid anesthesiologists in developing more evidence-based practices,thereby improving the safety and outcomes for elderly patients undergoing gastroenteroscopy.

Safety and efficacy comparison of remimazolam and propofol for intravenous anesthesia during gastroenteroscopic surgery of older patients:A meta-analysis

BACKGROUND Remimazolam is characterized by rapid action and inactive metabolites.It is used as the general anesthetic for many clinical surgeries.In this study,we performed a meta-analysis to evaluate whether remimazolam is superior to propofol for gastroenteroscopy in older patients.AIM To compare the adverse events and efficacy of remimazolam and propofol during gastroenteroscopy in older adults.METHODS The PubMed,Web of Science,the Cochrane Library databases were queried for the relevant key words"remimazolam,""and propofol,""and gastrointestinal endoscopy or gastroscopy."The search scope was"Title and Abstract,"and the search was limited to human studies and publications in English.Seven studies wherein remimazolam and propofol were compared were included for the metaanalysis.RESULTS We selected seven randomized controlled trials involving 1445 cases for the analysis.Remimazolam reduced the hypotension(relative risk,RR=0.44,95%CI:0.29-0.66,P=0.000),respiratory depression(RR=0.46,95%CI:0.30-0.70,P=0.000),injection pain(RR=0.12,95%CI:0.05-0.25,P=0.000),bradycardia(RR=0.37,95%CI:0.24-0.58,P=0.000),and time to discharge[weighted mean difference(WMD)=-0.58,95%CI:-0.97 to-0.18,P=0.005],compared to those after propofol administration.No obvious differences were observed for postoperative nausea and vomiting(RR=1.09,95%CI:0.97-1.24,P=0.151),dizziness(RR=0.77,95%CI:0.43-1.36,P=0.361),successful sedation rate(RR=0.96,95%CI:0.93-1.00,P=0.083),or the time to become fully alert(WMD=0.00,95%CI:-1.08-1.08,P=0.998).CONCLUSION Remimazolam appears to be safer than propofol for gastroenteroscopy in older adults.However,further studies are required to confirm these findings.

Clinical Observation of Dexmedetomidine Combined with the Mixture of Propofol and Etomidate on Painless Gastroscopy in Children

Objective:To observe the anesthetic effect of dexmedetomidine combined with the mixture of propofol and etomidate on painless gastroscopy in children.Methods:A total of 80 pediatric patients who underwent painless gastroscopy in the Guangxi Minzu Hospital from January 2019 to September 2020 were randomly divided into two groups,A and B,with 40 patients in each group.Group A was given A mixture of etomidate 20 mg and propofol 0.2g,Dexmedetomidine was pumped into group B 10min before surgery,0.4 g/kg.HR,SBP,DBP,SpO2 and BIS were continuously monitored after entering the room.The doses of propofol and etomidate were recorded,as well as the time of waking and leaving the hospital.Adverse reactions such as hypotension,hypoxemia,nausea,vomiting and dizziness were recorded too.Results:Compared with group A,the dosage of propofol and etomidate in group B was significantly reduced(P<0.001),the time of waking and out of the chamber were significantly shortened(P<0.001),the body movement in the incidence of intraoperative was significantly reduced(P<0.001),and the nausea,vomiting and dizziness in the incidence of postoperative were significantly reduced(P<0.05).Conclusion:Dexmedetomidine combined with propofol and etomidate mixture can be safely used in painless gastroscopy in children,which can significantly reduce the dosage of propofol and etomidate,reduce the occurrence of adverse reactions,and shorten the time of resuscitation and discharge.
