目的 :分析白内障超声乳化吸除术中患者血压升高的原因。方法 :10 0例白内障患者随机分为两组 ,各 5 0例 ,手术时一组用局部注射麻醉法 ,另一组用表面麻醉法。通过监护仪监测此 10 0例白内障超声乳化吸除术患者术中血压的变化情况。两组结果予以比较。结果 :局麻组术中血压升高的发病率明显高于表麻组 ,血压升高主要发生在局部注射、上直肌固定、电凝这些疼痛明显的操作过程。结论 :白内障超声乳化吸除术中患者血压升高主要原因是疼痛刺激
Objective: To analyze the causes of elevated blood pressure in phacoemulsification cataract patients. Methods: One hundred and fifty cases of cataract were randomly divided into two groups (50 cases each). One group was operated on by local anesthesia and the other was treated by topical anesthesia. Monitor the changes of intraoperative blood pressure in 100 cases of phacoemulsification with cataract. Two sets of results to be compared. Results: The incidence of intraoperative hypertension was significantly higher in the local anesthesia group than in the ephedrine anesthesia group. Elevated blood pressure mainly occurred in the procedure of local injection, upper rectus muscle fixation and coagulation. Conclusions: The main reason for the elevated blood pressure in phacoemulsification cataract patients is painful stimulation
