ProSeal喉罩对老年乳腺癌根治术患者全身麻醉苏醒期的影响

Objective To explore the effect of ProSeal laryngeal mask airway and endotracheal tube on analepsia stage of general anesthesia in geriatric patients undergoing radical mastectomy.Methods Thirty geriatric females with breast cancer of American Standards Association (ASA)Ⅰ-Ⅱscheduled for selective radical mastectomy under general anesthesia were randomly allocated to two groups: ProSeal laryngeal mask airway group(PLMA group, n=15) and endotracheal tube group (ET group, n=15). The patients were put on PLMA or were intubated with ET under general anesthesia in the two groups, respectively. The heart rate (HR), systolic blood pressure(SBP)and diastolic blood pressure (DBP) were recorded at the time points of 5 min after entering operation room (T0), end of surgery (T1), opening eyes (T2), after extubation (PLMA) immediately (T3) and 3 min after extubation (PLMA) (T4). The numbers of patients who were given antihypertensive agent,showed bucking, agitation or sore throat, nausea and vomiting after extubation were recorded during the analepsia stage of general anesthesia. Results The blood pressure (BP) and HR were mildly.increased in PLMA group at T2, and there was no significant difference compared with T0(P＞0.05). But the BP and HR were significantly higher at T3 than at T0 (P＜0.05). In ET group, the BP and HR were both significantly elevated at T2 and T3 than at T0 (P＜0.05), and reached the peak at T3. The increased levels of BP and HR were significantly lower in PLMA group than in ET group at T2 and T3 (P＜0.05). The quantities of patients who were given antihypertensive agent, showed bucking and sore throat were less in PLMA group than in ET group(P＜0.05). No differences in incidence rate of agitation, nausea and vomiting after extubation between the two groups were observed(P＞0.05). Conclusions PLMA can obviously reduce the occurrence of complications in analepsia stage of general anesthesia in geriatric patients scheduled for selective radical mastectomy,and is beneficial to provide much safer anesthesia.
