目的
2
观察瑞马唑仑应用于颈动脉内膜剥脱术(CEA)患者全身麻醉对电生理监测指标及脑氧饱和度(ScO
2
)的影响。
方法
2
选取2022年7月至2024年6月于我院神经外科择期行CEA的患者,采用随机数字表法将其分为瑞马唑仑组(R组)和丙泊酚组(P组)。2组患者皆采用丙泊酚1.5~2.0 mg/kg、顺式阿曲库铵0.1~0.2
mg/kg和舒芬太尼0.3~0.4 μg/kg行麻醉诱导。麻醉维持:R组患者静脉泵注瑞马唑仑0.5~1.0 mg·kg
-1
·h
-1
,P组患者静脉泵注丙泊酚5.0~7.0 mg·kg
-1
·h
-1
,2组患者均复合静脉输注瑞芬太尼0.1~0.2 μg·kg
-1
·min
-1
进行麻醉维持。记录2组患者的手术时间、颈动脉阻断时间、术中输液量、瑞芬太尼及去甲肾上腺素用量、苏醒时间。观察并比较2组患者麻醉前(T0)、麻醉后(T1)、阻断前5 min(T2)、阻断后5 min(T3)、解除阻断后5 min(T4)、手术结束(T5)时的血流动力学与脑氧指标、诱发电位波幅及潜伏期,随访并统计患者术后并发症总发生率。
结果
2
与P组相比,R组患者术中去甲肾上腺素用量减少(
P
<
0.05),苏醒时间缩短(
P
<
0.05)。在T2时,R组患者的平均动脉压(MAP)高于P组(
P
<
0.05);在T3时,R组患者的ScO
2
明显高于P组(
P
<
0.05),运动诱发电位(MEP)潜伏期延长百分比与波幅降低百分比明显低于P组(
P
<
0.05),下肢感觉诱发电位(SSEP)波幅降低百分比低于P组(
P
<
0.05);在T5时,R组患者MEP波幅较T2时明显增高,P组患者MEP波幅较T2时降低,差异有统计学意义(
P
<
0.05)。2组患者术后并发症总发生率比较,差异无统计学意义(
P
>
0.05)。
结论
2
瑞马唑仑作为全身麻醉维持药物用于CEA可获得满意的麻醉效果,术中血流动力学更平稳,且于颈动脉阻断期间较丙泊酚对ScO
2
与诱发电位监测的影响更小,安全性更高。
Objective
2
To observe the effects of general anesthesia with remazolam on electrophysiological monitoring indicators and cerebral oxygen saturation (ScO
2
)in patients undergoing carotid endarterectomy (CEA).
Methods
2
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

·h

,while patients in the P group received intravenous infusion of propofol 5.0 to 7.0 mg·kg
-1
·h

. Both groups received intravenous infusion of remifentanil 0.1 to 0.2 μg·kg

·min

for anesthesi
a 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
2
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 ScO
2
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
2
As a general anesthesia maintenance drug,remazolam can achieve satisfactory anesthesia effects for CEA,with more stable intraoperative hemodynamics,an
d less impact on ScO
2
and evoked potential monitoring during carotid artery occlusion compared to propofol,resulting in higher safety.
