RESUMO
Objective To explore the effect of remimazolam combined with remifentanil on painless bronchoscopy in elderly patients and observe its impact on hemodynamics.Methods Collect 80 elderly patients underwent bronchoscopy examination from October 2021 to October 2022 as research subjects,and divide them into remifentanil group and combination group according to anesthesia methods.Remifentanil group was given remifentanil assisted painless bronchoscopy,and the combined group was given remimazolam assisted painless bronchoscopy based on remifentanil group.The hemodynamics and operation conditions of the two groups at different time points[before anesthesia induction(T1),at the time of transglottis(T2),1 min after transglottis(T3),5 min after transglottis(T4),at the end of the inspection(T5)]were compared,and the changes of intraoperative and postoperative adverse reactions of patients with different anesthesia methods were observed,and satisfaction analysis was conducted.Results Compared with remifentanil group,the heart rate(HR)in the combined group at T2,T3,and T4 was slower,percutaneous arterial oxygen saturation(SpO2)was lower at T3,T4,diastolic blood pressure(DBP)and systolic blood pressure(SBP)were higher in T2,T3,T4,and the differences were statistically significant(P<0.05).The onset time of drugs was shorter,the recovery time of patients was long,the incidence of hypoxemia,hypotension and HR slowdown was lower,the incidence of HR increased was higher,and the postoperative satisfaction was higher,with statistical significance(P<0.05).There was no statistically significant difference in the incidence of postoperative nausea,vomiting,dizziness,headache,and drowsiness between the two groups of patients(P>0.05).Conclusion Remimazolam combined with remifentanil for painless bronchoscopy in elderly patients may have a good application effect,which can maintain hemodynamic stability,rapid onset,long duration of efficacy,reduce the rate of intraoperative adverse reactions,have a good safety,and can improve patient satisfaction.
RESUMO
Objective To compare the anesthetic effect and safety of Ciprofol and Propofol combined with Fentanyl in painless bronchoscopy for conscious patients in intensive care unit(ICU).Methods 60 conscious patients who underwent painless bronchoscopy from October 2022 to January 2023 were selected.According to the random number table method,30 cases were divided into the control group(Propofol 1.5 mg/kg + Fentanyl 1 μg/kg)and 30 cases were divided into the experimental group(Ciprofol 0.4 mg/kg + Fentanyl 1 μg/kg).Systolic blood pressure,diastolic blood pressure,heart rate,respiratory frequency,and percutaneous arterial oxygen saturation(SpO2)were recorded before anesthesia(T1),during the examination(T2),and at the completion of the examination(T3)in the two groups,and the success rate of induction of general anesthesia,the time of induction of anesthesia,the time of bronchoscopy,the time of eye-opening,the total dosage of medications used,the incidence of injection pain,and the incidence of intraoperative adverse reactions(hypotension,respiratory depression,bradycardia,and bucking)in the two groups were compared.Results Analysis of the data revealed significant group,time,and interaction effects for systolic blood pressure,diastolic blood pressure,heart rate,and respiratory frequency at different time points(P<0.05).The experimental group had a shorter induction time of anesthesia[1.40(1.10,1.62)min]in comparison to the control group[1.60(1.30,2.10)min](P<0.05),and the experimental group required a less amount of drug to achieve the desired outcome[(21.40±1.82)mg]compared to the control group[(78.75±6.71)mg](P<0.05).Furthermore,the incidence of injection pain(3.33%)and respiratory depression(6.67%)was significantly reduced in the experimental group compared to the control group(36.67%)and(30.00%)(P<0.05).Conclusion The use of Ciprofol in combination with Fentanyl has been found to provide effective anesthesia during bronchoscopy,while also increasing safety and decreasing the incidence of adverse events.It is worthy of clinical application.
RESUMO
Objective To investigate the effect of remimazolam on anesthetic effect and postoperative cognitive function during painless bronchoscopy in elderly patients.Methods A total of 90 patients with painless bronchoscopy admitted to Wenzhou People's Hospital were selected.And randomly dividing into 45 patients in control group,45 patients in observation group.The control group was given propofol,and the observation group was given remimazolam.Mean arterial pressure(MAP),heart rate(HR),and blood oxygen saturation(SpO2)were monitored.Effective time after induction,recovery time after withdrawal and discharge time were compared.Patient's cognitive function was assessed using the mini-mental state examination(MMSE),auditory word learning test(AVLT),shape connection test(STT),and animal language fluency test(AFT).Enzyme linked immunosorbent assay(ELISA)was used to determine substance P(SP),C-reactive protein(CRP),noradrenaline(NE),tumor necrosis factor-α(TNF-α)in serum,interleukin(IL)-6 and prostaglandin E2(PGE2)concentrations.Results Compared with the control group,the MAP of the observation group patients at time points T2 and T3 showed statistically significant differences(P<0.05);HR was especially significant at T2,T3 and T6 periods(P<0.05).SpO2 at T2 and T3(P<0.05).The awakening time,discharge time of the observation were shorter than control(P<0.05).At 1 day after surgery,the MMSE score,STT score,AFT score were significantly higher(P<0.05);The serum levels of SP,PGE2 and NE and IL-6,TNF-α and CRP were decreased in the control(P<0.05).The incidence of adverse reactions was 17.78％in control group and 8.89％in observation group(χ2=7.654,P=0.031).Conclusion Remazolam is used in painless bronchoscopy in elderly patients,intraoperative hemodynamics is stable,having little impact on postoperative cognitive function,and inhibits the release of inflammatory factors and the secretion of pain mediators,which is worthy of clinical use.
