Abstract:
Objective:To investigate the safety and efficacy of remimazolam combined with afentanyl for fiberoptic bronchoscopy.Methods:Sixty patients admitted to Chifeng Hospital for fiberbronchoscopy from January to April 2022 were selected and divided into two groups by random number table method: remimazolam group (group R) and propofol group (group P), 30cases in each group. After intravenous injection of alfentanil for anesthesia induction, group R was sedated by intravenous injection of remidazolam besylate, and group P was sedated by intravenous injection of propofol emulsion. When sufficient sedation was achieved, fiberoptic bronchoscopy was performed. The patients were scored with the Mini-Mental State Examination (MMSE) before examination and before leaving the room. The recovery rate of sedation and the recovery rate of drugs during operation were compared. Blood pressure, heart rate (HR), bispectral index (BIS), SpO 2 value and Modified Observer′s Assessment of Alertness/Sedation (MOAA/S) score were compared before induction (T 0), at the beginning of examination (T 1), immediately when fiber bronchoscope reached juga (T 2), at the end of surgery (T 3), immediately, when patients regained consciousness (T 4). Drug onset and recovery time (time out of hospital) as well as the incidence of intraoperative and postoperative adverse reactions were recorded in both groups. Results:There was no statistically significant difference in general condition, MMSE score and examination time between the two groups (all P>0.05). There was no statistically significant difference between the two groups in the success rate of sedation and the number of sedative remedy times (all P>0.05). The number of additional drugs in group R was significantly higher than that in group P ( P<0.05). The systolic blood pressure, diastolic blood pressure and BIS values of patients in group P at T 1 and T 2 were significantly lower than those in group R (all P<0.05). After administration, the MOAA/S score of the two groups began to decrease, and the decrease of the P group was significantly greater than that of the R group, and the MOAA/S value of the patients was the lowest at the 3rd and 4th minutes after administration, respectively. The time from the beginning of administration to the MOAA/S score ≤3 in group P was significantly shorter than that in group R (all P<0.05). The incidence of pain and respiratory depression after injection in group P was significantly higher than that in group R ( P<0.05). Conclusions:The application of afentanil combined with remimazolam in the patients undergoing fiberoptic bronchoscopy has good sedative effect and high anesthesia quality, and has no obvious effect on cognitive function and few adverse reactions, so it is safe and effective.
