Influence of Gastric Tube Presence in Upholding the Correct Placement of LMA Blockbuster
Condition: Anesthesia
Study type: Observational

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.
    

Detailed description: 
      Following approval by the Board of studies, Department of anaesthesiology and ethical
      committee of this institution the study will be conducted in J N Medical College and hospital
      on 60 patients undergoing operative procedures under general anaesthesia. Patients will be
      included in the study after well informed written consent, including the information that
      they would be part of this ongoing institutional research.

      STUDY DESIGN Prospective randomised controlled study

      STUDY POPULATION The study will be conducted on 60 patients admitted to JNMCH, AMU Aligarh
      planned for operative procedure under general anaesthesia.
