Title: Effects of combination of laryngeal mask airway and epidural anesthesia on hemodynamics for hypertensive patients
Abstract: Objective To evaluate the influences of laryngeal mask airway(LMA) combined with epidural anesthesia on hemodynamics in hypertensive patients.Methods 72 gynecological patients with stage Ⅰ to Ⅱ hypertension were randomly divided into four groups(n=18 for each):general anesthesia with tracheal intubation(group G) or LMA(group L),combination of epidural anesthesia and general anesthesia with tracheal intubation(group GE) or LMA(group LE).BP,HR,ECG,SpO2 were monitored in different time.Intraoperative awareness,the time of extubation or LMA removal and anesthetic dosages were recorded.Results During insertion of the tube or LMA,SBP,DBP,HR were significantly higher than those before anesthesia in group G and GE(P0.05),but there were no significant change in group L and LE.During exploration,SBP,DBP,HR were significantly higher than those before anesthesia in group G and L(P0.05),but there were no significant change in group GE and LE.During extubation or LMA removal,SBP,DBP were significantly higher than those before anesthesia in group G and GE(P0.05),HR was significantly higher than that before anesthesia in group G and L(P0.05),but there was no significant change in group LE.The time of extubation or LMA removal in group LE[(11±4)min] was significantly shorter than in that other groups[group G(35±11)min,group GE(21±7)min,group L(28±8)min](P0.01).Conclusion LMA combined with epidural anesthesia could maintain more stable hemodynamics for hypertensive patients,it reduces anesthetic dosage with rapid awakening and LMA removal.
