INTRODUCTION

Positive pressure ventilation has frequently been used with the LMA-Classic in non-obese patients.1 The ProSeal LMA2 incorporates a posterior inflatable cuff for higher airway pressure without leak, and a second, open ended tube for blind passage of a gastric tube. We compared ProSeal LMA with tracheal tube (ETT) during elective laparoscopic cholecystectomy.

METHODS

Patients aged >=18 yr, ASA I - III were randomized to ProSeal LMA or ETT, and stratified as non-obese (BMI <=30 kg.m-2) or obese (BMI >30 kg.m-2). Following preoxygenation, anesthesia was induced using propofol, fentanyl and rocuronium. The ProSeal LMA (#4 for women, #5 for men) or ETT (7 mm for women, 8 mm for men) was inserted and anesthesia maintained with isoflurane and nitrous oxide in 30-50% oxygen, VT10 mL.kg-1 at a rate of 10.min-1. A #14 gastric tube was passed in every patient and connected to continuous suction. Ventilation parameters were recorded as baseline (before peritoneal insufflation) and as insufflation (during peritoneal insufflation). The surgeon, blinded to the type of airway, assessed gastric size on a 0-10 scale at insertion of the laparoscope and at the end of the procedure.

RESULTS

Demographic data, anesthetic time, peritoneal insufflation time, and gastric distension scores were similar in both groups. Ventilation parameters are shown in the TableGo.

DISCUSSION

The ProSeal LMA provides effective ventilation without gastric distension, even in obese patients with increased intra-abdominal pressure, during laparoscopic cholecystectomy.
