Objective To assess the efficacy of laryngeal mask airway Supreme (LMA Supreme) used in patients undergoing laparoscopic surgery. Methods One hundred and twenty ASA I or Ⅱ patients of both sexes aged 35-60 yr weighing 48-85 kg undergoing elective laparoscopic surgery were randomized to 2 groups ( n = 60 each): LMA Supreme group (group S) and tracheal intubation group (group T). Mallampati test was performed before operation in both groups. The patients were classified as I - Ⅲ . In group S the LMA Supreme was inserted after induction of anesthesia with sufentanil 0.2 fig/kg, propofol 2-3 mg/kg and vecuronium 0.1 mg/kg. A gastric tube was inserted through the drain tube of the LMA Supreme. In group T the patients were intubated under direct laryngoscopy. The success rate, LMA placement/intubation time, success rate of gastric tube placement, airway seal pressure, SpO2, PETCO2 , peak airway pressure and complications (hypoxemia, nausea and vomiting, choking hoarseness, sore throat and regurgitation of gastric contents) were recorded. The duration of surgery, anesthesia time, extubation time and emergence time were also recorded. Results There was no significant difference in the success rate between the two groups. The placement and removal time and recovery time were significantly shorter in group S than in group T. The airway seal pressure was (25 ±4) cm H2O in group S. SpO2, PETCO2 and peak pressure were within normal range in both groups. The incidence of postoperative hypoxemia, choking and sore throat were significantly lower in group S than in group T. Conclusion LMA Supreme can provide adequate ventilation during operation with less complications and can be used effectively for laparoscopic surgery.

Objective To evaluate the efficacy of streamline liner of pharyngeal airway ( SLIPA) in airway management of general anesthesia. Methods Sixty ASA Ⅰ -Ⅱ patients undergoing elective breast surgery were randomized into 2 groups (30 cases each): SLIPA group (group S) and laryngeal mask airway (LMA) classic group (group L). Anesthesia was induced with propofol 2 mg/kg, sufentanil 0.15 μ g/kg and vecurium 0.08 mg/kg. SLIPA or LMA was inserted with digital manipulation. Anesthesia was maintained with 1% - 2% sevofluran and 50% N2O in 50% oxygen. The parameters of controlled ventilation were same in both groups. The attempt times, seal pressure and grade of fiberoptic (FOB ) laryngoscopy were measured. SpO2, PErCO2 and peak airway pressure were monitored every 15 minutes after successful laryngeal mask insertion. The complications such as regurgitation of gastric contents and sore throat were assessed by anesthesiologist after surgery. Surgery time, anesthesia time, extubation time and emergence time were recorded. Results Success rate of LMA insertion in both groups were 100%. The first attempt success rates were 90%( 27/30) in group S and 60%( 18/30) in group L (P< 0.05), the FOB grade 4 were 67%(20/30) in group S and 37% (ll/30)in group L(P< 0.05), the maximum seal pressures were (23.6 ± 4.7)cmH2O (1 cm H2O = 0.098 kPa) in group S and (18.8 ± 4.5) cm H2O in group L (P<0.05). SpO2, PErCO2 and peak airway pressure were within normal ranges. The occurrence of sore throat was similar in group S and group L (7 cases vs 6 cases). No signs of regurgitation were detected. Conclusion The SLIPA proved to be a simple, safe and effective airway instrument with little complications during the course of general anesthesia.
