THE APPLICATION OF PROSEAL LARYNGEAL MASK AIRWAY FOR LAPAROSCOPY OF GYNECOLOGICAL EMERGENCIES

Objective To explore the feasibility and superiority of using Proseal laryngeal mask airway(PLMA)in gynecological emergencies.Methods Twenty ASAI-II patients with emergencies of ectopic pregnancy aged 22~32 years undergoing laparoscopy were divided into two groups of ten each:Proseal laryngeal mask airway group(L)and endotracheal tube group(E).The patients in group L were conducted of PLMA insertion,while those in group E were performed endotracheal intubation with tracheal tube after induction of anesthesia.All the patients were performed controlled-ventilation.SBP,DBP,HR,SpO2,Ppeak,PETCO2,VT,PaCO2 were monitored at seven time-points:before anesthesia(T0),before insertion of tracheal tube and PLMA(T1),at once after insertion of tracheal tube and PLMA(T2),5min(T3),20min(T4)after insertion,extubation(T5)and 5min after extubation(T6).The parameters measured included cases of difficult insertion or intubation,time of analepsia,cases of celostomia and cough.Results Ppeak、VT,SpO2,PETCO2 and PaCO2 remained unchanged before,during and after surgery in both groups(p0.05).BP and HR at T0 and T1 time points ware similar.BP and HR at T2 and T5 time points increased significantly than that of T0 and T1 time points in group E(p0.05).BP,HR in group E increased significantly than that in group L at T2 and T5 time points(p0.05).Bp,HR,at each time point ware similar in group L(p0.05).SpO2,PETCO2 at the same time point ware similar between the two groups.The retaining time of PLMA was(43.3±9.6)min.The complications after operation included cough(60%),sore-throat(28%)in group E,and there is nothing in group L.Conclusion PLMA can provide the same safe and effective ventilation as tracheal intubation in general anesthesia for gynecological emergencies.Compared with endotracheal intubation,PLMA was easy to use.the stress of patients was low.PLMA avoid the occurrence of complications of pharynxand laryngeal.
