Abstract:
Objective To assess the efficacy of laryngeal mask airway Proseal (LMA Proseal) and Supreme (LMA Supreme) used in patients undergoing laparoscopic surgery when the cuff-pressure was 35 cm H2O.Methods Sixty ASA Ⅰ or Ⅱ patients, aged 20-70 yr, weighing 50-80 kg, undergoing elective laparoscopic surgery, were randomized into2 groups (n = 30 each): LMA ProSeal group (group P) and LMA Supreme group (group S). After the LMA Proseal and LMA Supreme were inserted in group P and S respectively, the cuff pressure was monitored and maintained at 35 cm H2O by manipulate manometer. The airway sealing pressure, peak and mean airway pressure before and after pneumoperitoneum during mechanical ventilation and the complications were also recorded. Results The peak airway pressure was significantly higher after pneumoperitoneum than before pneumoperitoneum during mechanical ventilation (P ＜ 0.05), but there was no significant difference in the peak airway pressure before and after pneumoperitoneum between the two groups ( P ＞ 0.05). The air leakage had never happened before or after pneumoperitoneum during mechanical ventilation. There was no significant difference in the airway sealing pressure between the two groups ( P ＞ 0.05). There was no significant difference in the incidence of throat pain between the two groups(P＞0.05).Conclusion When the cuff pressure is 35 cm H2O, the LMA ProSeal and Supreme can provide adequate ventilation during operation with fewer complications and can be used safely for laparoscopic surgery.
