诱导性升/降压技术在颈动脉内膜斑块切除术中的应用及疗效
Application and efficacy of induced hypertension and hypotension in carotid endarterectomy
目的 探讨诱导性升降压在颈动脉内膜斑块切除术(carotid endarterectomy,CEA)中的安全性及有效性.方法 回顾性分析2012年8月至2018年8月于国内多中心收治的1 486例颈动脉狭窄患者,经筛选共纳入1 448例患者符合入组标准,在CEA术中均使用诱导性升降压技术.结果 共纳入1 448例患者,手术侧颈动脉重度狭窄患者占87.8%.评估代偿血管情况,平均手术时间(51.8 ±6.1)min,颈内动脉阻断时间(11.4±3.1)min.经诱导性升压后,所有患者残端压均升高,其中1 438例(99.3%)>50 mmHg.监测脑电氧饱和度,阻断前未升压时,术侧较对侧明显降低[(56%±3%)比(64%±4%),P<0.05];诱导性升压后,术侧rSO2较对侧rSO2低,但差异无统计学意义[(66%±3%)比(70%±2%),p>0.05];颈动脉开放后,术侧rSO2较对侧rSO2低,但差异无统计学意义[(68%±5%)比(69%±3%),P>0.05].围手术期共发生脑梗死2例,同侧脑出血1例,对侧脑出血1例,心肌梗死2例.结论 CEA术中使用诱导性升降压技术可起到临时脑保护作用,初步证明了诱导性升降压技术的安全性及有效性.
更多Objective To evaluate the safety and efficacy of induced hypotension and hypotension in carotid endarterectomy (CEA).Methods Data of 1 486 patients who underwent CEA in multicenters from Aug 2012 to Aug 2018 were retrospectively analyzed.After screening,a total of 1 448 patients met the inclusion criteria.Induced hypertension and hypotension was used in all thees patients.Results 87.8% of the patients were with severe carotid stenosis.The average operative time was (51.8 ± 6.1) min,and the internal carotid artery clamping time was (11.4 ± 3.1) min.After induced hypertension,the stump pressure were higher than that before,of which 1 438 (99.3%) were greater than 50 mmHg.Monitoring of EEG oxygen saturation showed that the value of ipsilateral rSO2 was significantly lower than that of the contralateral [(56% ± 3%) vs.(64% ± 4%),P < 0.05] before induced hypertension.After induced hypertension and clamp removal,the value of ipsilateral rSO2 was lower than that of the contralateral,but there was not significant difference (all P > 0.05).Perioperative cerebral infarction occurred in 2 cases,ipsilateral cerebral hemorrhage in 1 case,contralateral cerebral hemorrhage in 1 case and myocardial infarction in 2 cases.Connclusion The technique of induced hypotension and hypotension play a temporary role in brain protection for patients undergoing CEA.This study demonstrated the safety and effectiveness of induced hypertension and hypotension technique.
