Comparison of ProSeal laryngeal mask airway and endotracheal intubation in the laparoscopic cholecystectomy in the elderly patients

Objective To evaluate the effects of ProSeal laryngeal mask airway(PLMA) and endotracheal intubation on hemodynamics and airway resistance.Methods Eighty elderly patients aged 65-79 years scheduled for selective laparoscopic cholecystectomy were randomly divided into 2 groups(n = 40,respectively): PLMA group(group P) and endotracheal intubation group(group T).SBP,DBP,HR and SpO2 were recorded at 6 time pionts:before anesthesia induction(T0),1 min(T1),5 min(T2) after intubation,20 min after pneumoperitoneum(T3),befor extubation of PLMA or tracheal(T4),and after extubation(T5),Pmean,Ppeak and PETCO2 were measured at T1-T3 under the tidal volume in 8 mL/kg respectively.And the availability of intraoperative aspiration of reflux and postoperative throat complications were observed.Results In group T,SBP,DBP and HR at T1,T4,T5 were higher than T0 and at the same time points in group P(P 0.05);the Pmean,Ppeak and PETCO2 were within the normal range during operation in the both groups;the cases of postoperative throat discomfort in group T(11 cases) were more than in group P(3 cases)(P 0.05).Conclusion ProSeal laryngeal mask airway induces less stress reaction and has fewer complications of throat after operation in the elderly undergoing laparoscopic cholecystectomy;application of PLMA in elderly group can improve respiratory function by reducing the incidents of complications of trachea cannula,and increase the security of elderly patients during general anesthesia.
