Clinical Trial Summary

Baska mask is a new novel supraglottic airway device with many salient features. The investigators aim to determine the benefit of BASKA mask as an effective airway device for laparoscopic surgery, and whether it can even substitute endotracheal intubation, in order to smoothen the surgery and anaesthesia process as well as reduce perioperative complications.

Description:

Patient's satisfaction and smooth process is crucial for perioperative care.Conduct of Anaesthesia including choice of airway devices play an important role. Endotracheal intubation has long been regarded as the technique of choice for airway management in laparoscopic surgery. However, there is currently an emerging interest in laryngeal mask as the substitute for endotracheal tube in laparoscopic surgery.

The increased abdominal pressure secondary to gas insufflation in Laparoscopic surgery demands a good supraglottic airway device with features of good seal, aspiration prevention and effective ventilation.

Few studies have evaluated the performance Baska® Mask for various type of surgery and had obtained high "first-attempt" success rate, easy insertion and a good oropharyngeal leak pressure above 30cmH2O with low complications such as sorethroat, dysphonia and dysphagia.

However, study regarding comparison of Baska® mask with endotracheal tube has not been carried out before. Therefore, the investigators would like to evaluate this novel device in comparison with endotracheal tube for laparoscopic surgery in our centre.

This will be a prospective randomized controlled study in University Malaya Medical Centre to compare Baska® mask with the conventional laryngoscope-guided endotracheal intubation for laparoscopic surgeries.

The investigators would like to study the efficacy of this device in term of : time to effective airway insertion, efficacy of airway seal, post-operation device of complications.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	oropharyngeal leak pressure (OPL) of the device during operation	the above pressure is measured by performing the maneuver: the expiratory valve of the anaesthetic machine is closed and with a fixed gas flow of 3 L/min, the airway pressure at which equilibrium is reached is recorded. Maximal allowable airway pressure is 40 cm H2O [ OLP is measured at following timeframe - T1: immediately post intubation; T2 : before CO2 insufflation; T3 : after CO2 insufflation; T4 and beyond : each change of position as required during operation (eg. Trendelenburg, reverse Trendelenburg, left tilt)	during operative duration
Other	peak airway pressure of the device during operation	the above pressure is recorded from the anaesthetic machine at following timeframe - T1: immediately post intubation; T2 : before CO2 insufflation; T3 : after CO2 insufflation; T4 and beyond : each change of position as required during operation (eg. Trendelenburg, reverse Trendelenburg, left tilt)	during operative duration
Primary	Time to effective airway insertion	defined as time from picking up the airway device (either BASKA mask or Endotracheal tube), insertion and until occurrence of the first square-waveform capnogram	1 hour
Secondary	Numbers of attempt of airway device insertion and Ease of insertion	defined as: 1 - first attempt easy, smooth insertion; 2 - second attempt, insertion with resistance; 3 - three attempts, insertion with difficulty; 4 -failed insertion of the SGAs and need to crossover to ETT group	1 hour
Secondary	Gastric distension scoring by surgeon	on a visual analogue scale 0-10 (Figure 2), where 0 = empty stomach, and 10 = heavy distension that interfered with surgical exposure at a) entry of the laparoscope following peritoneal insufflation and b) immediately before removal of the laparoscope at the end of the surgical procedure	during operative duration
Secondary	Post operation incidence of complications	patients are assessed for the incidence of sore throat, airway trauma (lip, tongue, teeth, blood-staining on device), nausea, vomiting, airway spasm, aspiration, emergence cough	from the induction of anaesthesia, until at the postanaesthetic care unit (PACU), assessed up to 24 hours
Secondary	Hemodynamic changes	Blood pressure and Heart rate	after induction of anaesthesia at 1, 2, 3,4,5,10,20,30 minutes; then post extubation at 1 ,2,3,4,5 minutes
