Title: Observation of ventilation effect of OPLAC-LMA in laparoscopic operation
Abstract: Objective To compare the ventilation effect between conventional endotracheal intubation and OPLAC-LMA in laparoscopic operation. Methods One hundred cases of patients with ASA Ⅰ-Ⅱ grade, BMI30 kg/m2 underwent laparoscopic operation were randomly divided into endotracheal intubation group (group A, n = 50) and OPLAC-LMA group (group B, n = 50). Two groups were all treatment with target controlled infusion of Propofol (target concentrations of plasma was 3-5 μg/mL) and Remifentanil (target concentrations of plasma was 4-6 ng/mL), intravenous injection of Vecuronium 0.12 mg/kg, then the appropriate type of tracheal catheter or OPLAC-LMA was inserted or placed when the BIS was 40-60. After successful placement, the tracheal catheter inserted time, LMA placement time, the success rate of one-time placement, airway sealing pressure, occurrence of cough, vomiting, breath-holding and laryngeal spasm when extubation, incidence of pharyngeal pain and pulmonary infection after 24 h of operation were recorded. Intraoperative BP, HR, ECG, SpO2, PETCO2, PpeaK, PCO2 were continuous monitored, and the operation time, time, pneumoperitoneum time, awake time, extubation time were record. Results The differences in placement time, success rate of one-time placement, airway sealing pressure, awake time, occurrence of cough, vomiting, breath-holding and laryngeal spasm when extubation, incidence of pharyngeal pain and pulmonary infection after 24 h of operation of two groups were not significant (P 0.05). Intraoperative hemodynamics was smooth of patients in two groups, the SpO2, PETCO2, PpeaK, PCO2 were all in the normal range, and the differences of two groups were not significant (P 0.05). Conclusion OPLAC-LMA can be used in upper abdominal laparoscopic operation effectively, which has good safety. Compared with traditional tracheal intubation, the ventilation effect of OPLAC-LMA has no significant difference, and at present the use ratio of it in general anesthesia is greater than conventional tracheal intubation in some countries and regions. With the continuous improvement of LMA, it almost can replace endotracheal intubation.
