Effects of remazolam on neuroelectrophysiological and cerebral oxygen monitoring in carotid endarterectomy
摘要
Abstract
Objective To observe the effects of general anesthesia with remazolam on electrophysiological monitoring indicators and cerebral oxygen saturation(ScO2)in patients undergoing carotid endarterectomy(CEA).Methods Patients who underwent elective CEA from July 2022 to June 2024 in neurosurgery department of our hospital were randomly divided into the ramazolam group(R group)and the propofol group(P group).Patients in both groups were given propofol 1.5 to 2.0 mg/kg,cisatracurium 0.1 to 0.2 mg/kg,and sufentanil 0.3 to 0.4 μg/kg for anesthesia induction.Anesthesia maintenance:patients in the R group received intravenous infusion of remifentanil 0.5 to 1.0 mg·kg-1·h-1,while patients in the P group received intravenous infusion of propofol 5.0 to 7.0 mg·kg-1·h-1.Both groups received intravenous infusion of remifentanil 0.1 to 0.2 μg·kg-1·min-1 for anesthesia maintenance.The operation time,carotid artery occlusion time,intraoperative infusion volume,remifentanil and norepinephrine dosage,and awakening time of patients in the two groups were recorded.The hemodynamic and cerebral oxygen indicators,amplitude and latency of evoked potentials before anesthesia(T0),after anesthesia(T1),5 minutes before blockade(T2),5 minutes after blockade(T3),5 minutes after unblocking(T4)and at the end of surgery(T5)of patients in the two groups were observed and compared,and the total incidence of postoperative complications was followed up and calculated.Results Compared with the P group,the dosage of intraoperative norepinephrine of patients in the R group was reduced(P<0.05),and the awakening time was shortened(P<0.05).At T2,the average arterial pressure(MAP)of patients in the R group was higher than that in the P group(P<0.05).At T3,the ScO2 of patients in the R group was significantly higher than that in the P group,and the percentages of prolonged latency and decreased amplitude of motor evoked potentials(MEP)were significantly lower than those in the P group(P<0.05),the percentage of decreased amplitude of lower limb somatosensory evoked potentials(SSEP)was lower than that in the P group(P<0.05);At T5,the MEP amplitude of patients in the R group was significantly increased compared to that at T2,while the MEP amplitude of patients in the P group was significantly decreased compared to that at T2,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the total incidence of postoperative complications between the two groups(P>0.05).Conclusion As a general anesthesia maintenance drug,remazolam can achieve satisfactory anesthesia effects for CEA,with more stable intraoperative hemodynamics,and less impact on ScO2 and evoked potential monitoring during carotid artery occlusion compared to propofol,resulting in higher safety.关键词
