Brief Summary

Since its invention in 1981 by Dr. Archie Brain, the classical laryngeal mask airway (LMA ) has undergone many modifications. Today various LMAs are available that can also help in Ryle's tube insertion, intubation via LMA, deep extubation, adjunct in difficult airway and for spontaneous ventilation in short procedures. One of the newer modifications is the Blockbuster LMA. It was invented by Prof. Ming Tian, the president of Chinese Difficult Airway Society and is being increasingly used for cases of difficult intubation. It has some unique features like its 95 degrees angulated airway that makes it easier to insert. It also has a gastric port and provides better sealing pressures at lower volumes. However the one of the major concern with supraglottic airway is that despite correct placement it may dislodge, or its position may change intraoperatively especially in surgeries where patient position needs to be changed or patient is moved/transferred or head and neck surgeries. In this study investigator wishes to evaluate weather gastric tube inserted through LMA helps in maintaining the LMA blockbuster placement by comparing fibreoptic bronchoscope (FOB) scores recorded immediately after LMA placement and at the end of the surgical procedure.

Conditions

Anesthesia

Outcome Measures

Primary Outcomes (1)

• POGO SCORE

  Grading the placement of LMA blockbuster through Fibreoptic Bronchoscope score of at the start and end of the surgery.

  IMMEDIATELY AFTER LMA PLACEMENT AND AT THE END OF SURGERY JUST BEFORE REMOVAL OF LMA

Secondary Outcomes (1)

• GASTRIC TUBE INSERTION SUCCESS RATE

  within 2 minutes of LMA Blockbuster placement

Interventions

LMA BLOCKBUSTER DEVICE

In this study we wish to evaluate weather gastric tube inserted through LMA helps in maintaining the LMA blockbuster placement by comparing fibreoptic bronchoscope (FOB) scores recorded immediately after LMA placement and at the end of the surgical procedure.

Also known as: GASTRIC TUBE
