Application With SLIPA Mask Or Endotracheal Intubation In Elder Colorectal Cancer Patient With Laparoscopic Surgery

Objective:To assess the hemodynamic alteration, effectiveness and safety for airway management using streamlined liner of the pharynx airway (SLIPA) compared with endotracheal tube (TT) in laparoscopic surgery in elder colorectal cancer patiencts.Method:Eighty-one cases of colorectal cancer patient were randomly divided into two groups. Patinets in groupd I were applied with endotracheal intubation during anesthesia (n=42cases, TT group), patinent in group II were used SLIPA laryngeal mask (n=39cases,SLIPA group). During the surgery, the position of the SLIPA laryngeal mask was observed. The heart rate, mean arterial pressure, oxygen saturation were recorded. Peak inspiratory airway pressure, airway compliance, airway resistance were mornitored too. Also, oxygen saturation, end-tidal carbon dioxide partial pressure and blood gas were analyzed during the surgery. After surgery, adverse events were observed. Results:1. At the time piont of endotracheal intubation or placing the LMA, MAP and HR variation in TT group significantly increased when compared to SLIPA group (P<0.05). During the surgery, the MAP and HR variation in TT group was more stable than these in SLIPA group (P<0.05).2. The end expiratory carbon dioxide partial pressure was significantly lower in TT group than those in SLIPA group (P<0.05). At the recovery period, TT group had significantly higher SPO2level than SLIPA group (P<0.05), as well as TT group had lower carbon dioxide partial pressure showed by gas analysis (P<0.05).3. The peak airway pressure, airway plateau pressure, airway compliance and airway resistance were significantly decreased in TT group than those in group SLIPA duiring the surgery (P<0.05).4. In the recovery period, the accidence of irritability, regurgitation and aspiration were significant higher in SLIPA group than those in TT group. Also the cases need to transfer to intensive care unit in group SLIPA increased significantly compared to in group TT (P<0.05).Conclusion:Compared to SLIPA, endotracheal intubation applied in laparoscopic surgery in elder colorectal cancer patiencts showed more stable hemodynamic and respiratory parameters, and less adverse effection.
