Application Of Oro-Pharyngeal Airway Cap In Laparoscopic Varicocelectomy

Objective To observe the feasibility and the safety of application of Oro-Pharyngeal airway Cap and classic LMA in laparoscopic varicocelectomy,and the characteristics of OPLAC compared to classic LMA.Methods Sixty ASA I-II patients, scheduled for laparoscopic varicocelectomy were randomly assigned to ET group(n=20),classic LMA group(n=20)and OPLAC group(n=20). After standard intravenous anesthetic induction, insertion of OPLAC,classic LMA and ET was performed. MAP, HR and SpO2 were recorded before anesthesia induction(T1) ,before intubation(T2) ,after intubation immediately(T3) ,at 3 min after intubation(T4), before CO2 pneumoperitoneum(T5 ),at 10 min after CO2 pneumoperitoneum(T6),the moment of respiratory restoration(T7), after extubation immediately(T8), 10 min after extubation(T9); implantation time,frequency of placement,number of intraoperative leakage and pertinent side-effects(tachycardia, hypertension, restlessness during recovery, throat discomfort, nausea and vomiting, hiccup) were monitored and recorded. Results In group ET, MAP,HR were significantly higher than those in group classic LMA and group OPLAC at implantation period,the resumption of spontaneous breathing period and removal period(P〈0.05);In there groups ,Pmax,PETCO2 were easily affected by pneumoperitoneum(P〈0.05),but there is no difference between the there groups(P >0.05) ;In all observe periods,there is no SpO2 difference between the two groups(P>0.05); In group OPLAC, the insertion time were shorter than those in group classic LMA and group ET(P〈0.05);In group ET, intraoperative and postoperative complications were significantly higher than those in group classic LMA and group OPLAC(P〈0.05).Conclusion Compared with ET use in laparoscopic varicocelectomy, OPLAC is simple use,have less stress reaction,have less complications; Compared with classic LMA of insertion, OPLAC is more simple and fast ;OPLAC can be safely and effectively used in laparoscopic varicocelectomy.
