老年人胆囊切除术中硬膜外与硬膜加全麻对循环的影响

Influence of Circulation Function under Epidural Block Anesthesia without or with Additional General Anesthesia in Cholecystectomy in Aged Patients

观察老年人硬膜外麻醉和硬膜外加全麻插管下胆囊切除术中循环的稳定程度。方法：６２例胆囊切除术患者随机分为两组。Ａ组（ｎ＝３２）硬膜外加全麻，Ｂ组（ｎ＝３０）硬膜外麻醉。观察术中心率、血压和血氧饱和度。记录因血压下降和心率减慢所用麻黄素和阿托品剂量。结果：两组病人术前患高血压和心脏病人无显著差异（Ｐ＞０２５），手术中麻黄素剂量Ａ组明显低于Ｂ组（Ｐ＜００５）；阿托品剂量Ａ组与Ｂ组无显著差异（Ｐ＞００５），两组均未使用抗高血压药物。

Objective: To observe the influence on circulation function under epidural block anesthesia without or with additional general anesthesia in aged patients receiving cholecystectomy. Methods: 62 aged patients were divided into 2 groups (A and B) randomly. Group A ( n =32) received epidural block anesthesia with additional general anesthesia and Group B ( n =30) received epidural block anesthsia only. During the operation, HR, BP, and SpO 2 were monitored. The doses of ephedrin and atropin used becaues of lowering blood pressure or decreasing heart rate were recorded. Results: The number of patients with hypertension and heart problem before operation had no significant difference ( P >0 25). During the operation, the dose of ephedrin in Group A was lower than that in Group B ( P <0 05); the dose of atropin used in Group A and Group B had no significant difference ( P >0 05); antihypertensive drug was not used in 2 groups. Conclusion: It is favorable for circulation function under epidural block anesthesia adding general anesthesia for aged patients receiving cholecystectomy.
