老年患者麻醉恢复延迟原因探讨

The Influential Factors of Postanesthesia Recovery Delay in Elderly Patients

【目的】探讨老年患者麻醉恢复延迟的原因。【方法】选取 2 2 2例择期手术老年患者 ,术毕收入麻醉后监测治疗室 (PACU) ,并分析性别、年龄、手术时间、全身麻醉、收入PACU状况、患恶性肿瘤等对患者麻醉恢复时间 (tr)的影响。【结果】 2 2 2例患者 ,平均tr=(76 17± 4 5 95 )min ,性别、全身麻醉对tr 无影响 (P >0 0 5 ) ;年龄、手术时间与tr 正相关 (r =0 2 3,0 33,P <0 0 1) ;收入PACU状况对tr 有影响 ,呼吸恢复欠佳患者tr=(10 3 33± 6 1 18)min麻醉恢复时间明显延长(P <0 0 1) ;恶性肿瘤患者tr,m=(88 0 4± 4 4 11)min比非肿瘤患者tr,n=(6 9 6 2± 4 5 77)min麻醉恢复明显延迟 (P <0 0 1)。【结论】高龄、长时间手术、呼吸恢复欠佳。

To evaluate factors which can delay postanesthesia recovery in elderly patients 222 old patients scheduled to operation were studied. They were all admitted to postanesthesia care unit (PACU) after operation Data were collected from these 222 patients The potential influential factors such as gender, age, operation time, general or local anesthesia, condition of patients and malignant or non malignant tumor were determined and analyzed The relationship between the above factors and the anesthesia recover time (t r) in PACU were studied. The mean t r was (76 17±45 95) min Gender and general anesthesia didn't affect t r (P>0 05) However the age, operation time contributed to t r significantly (r=0 23, 0 33,P<0 01) Patients' condition immediately admitted to PACU could affect t r, Patients with poor respiratory recovery showed longer t r than others (P<0 01) t r was significantly longer in patients with malignant tumor (79/222) than in those of non malignant tumor , [(t r,m vs t r,n ): (88 04±44 11) min vs (69 62±45 77) min, P<0 01]. [Conclusion] The study indicates that older age, longer operation time, poor respiratory recovery and malignant tumor are the important factors contributing to delay postanesthesia recovery in the elderly patients
