Overview
Brief Summary
We hypothesise that the use of the LMA-Supreme provides greater ease of insertion and reduced haemodynamic variability during insertion compared to the tracheal tube, whilst still maintaining a patent airway to facilitate elective laparoscopic cholecystectomy in selected patients.
Detailed Description
The Laryngeal Mask Airway Supreme(LMA-S) has been used successfully to maintain a patent airway for laparoscopic surgery. Our study compares the use of LMA-S with that of the tracheal tube (ETT) with respect to the ease of insertion and potential haemodynamic disturbance during insertion.

Outcomes
Primary Outcomes
Time to Effective Airway
Time Frame: Baseline
Time to achieve effective airway was defined as time between removing the face-mask, inserting the airway device and obtaining a sustained square-wave capnograph trace with manual ventilation
Secondary Outcomes
- Number of attempts taken for successful placement of airway device(Baseline)
- Peak airway pressure during pneumoperitoneum(Assessed intra-operatively, during the period of pneumoperitoneum)
- Incidence of post-operative sore throat(Assessed 1 hr after the surgery, at the Recovery Area)
- Number of attempts taken for successful placement of gastric tube(Baseline)
- Haemodynamic response to insertion of airway device(Baseline, 1 min, 5 min)
