About

Supraglottic Airway devices(SGAs) like I-Gel and C-LMA ( classic laryngeal mask airway ) have been used as a conduit for tracheal intubation using ventilating bougie. General Anaesthesia with tracheal intubation is one of the technique for giving anaesthesia. Tracheal intubation may become difficult sometimes and endangers patients life. Using SGAs as a conduit for tracheal intubation helps in securing airway. This will be further facilitated by using ventilating bougie, as it maintains oxygenation.

Full description

SGAs have been used as a conduit for tracheal intubation using ventilating bougie. Patients were anaesthetised with intravenous induction agent, non-depolarising muscle relaxant and then SGAs were inserted. Two groups were compared. In group I : I-gel was inserted, its position was confirmed and then ventilating bougie was inserted through it. It's position was confirmed, then I-gel was removed , Endotracheal tube was railroaded over ventilating bougie and it's position was confirmed. In group C : C-LMA was inserted, its position was confirmed and then ventilating bougie was inserted through it. It's position was confirmed, then C-LMA was removed , Endotracheal tube was railroaded over ventilating bougie and it's position was confirmed.

58 participants in 2 patient groups

Group-I

Active Comparator group

Description:

Tracheal intubation using I-gel and ventilating bougie insertion. In Group-I, following general anaesthesia I-gel is to be inserted, through it ventilating bougie is to be inserted then I-gel is to be removed and endotracheal tube is to be railroaded over ventilating bougie. Then ventilating bougie is to be removed.

Treatment:

Device: Tracheal Intubation using I-gel and ventilating bougie

Group-C

Active Comparator group

Description:

Tracheal intubation using C-LMA and ventilating bougie insertion. In Group-C, following general anaesthesia C-LMA is to be inserted, through it ventilating bougie is to be inserted then C-LMA is to be removed and endotracheal tube is to be railroaded over ventilating bougie. Then ventilating bougie is to be removed.
