A Comparison Of Ease Of Insertion AndWorking Performance Of Pro-seal And I Gel - The Supra Glottic Airway Devices In Elective Surgeries

I gel, PLMA, expired tidal volume, leak pressure, leak volumeAbstract
Background: PLMA has improved features of cuff design and incorporation of gastric drain channel led to
better seal achievement around the glottis. I gel single-use, cuff less, utilizes a thermoplastic elastomer to create a
more intimate interface for interaction with the supraglottic tissue. Supraglottic airway devices provide good seal
during anaesthesia for spontaneously breathing and controlled ventilation with moderate airway pressures.
Methodology: Hundred patients from routine elective surgical procedure were randomized to receive mechanical
ventilation, through either I gel or PLMA. Insertion characteristics, working performance, ease of gastric tube
insertion and hemodynamic characteristics was assessed. Results: The shorter insertion time (Group I was 20.98 ±
2.29 sec and Group P 30.04 ± 2.6 sec; P value <0.05) was found with I gel as compared to PLMA. There was no
statistical difference in insertion attempts, ease of insertion, failure of insertion and airway manipulation. The success
and ease of gastric tube placement was more with I gel than with PLMA. Expired tidal volume and leak pressures
were better with group P as compared to group I and the leak volume was insignificant in both the groups. The
incidence of sore throat and blood staining was similar in both the groups. Conclusion: In comparison to PLMA, I gel is
a cheaper, easier to insert, requires less manipulation and cuff inflation is not needed. It has other potential
advantages like easier gastric tube placement and fewer traumas to oropharyngeal structure.[Murthy A NJIRM 2016;
