Brief summary
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.
Detailed 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.
Interventions
DEVICETracheal Intubation using I-gel and ventilating bougie
Following general anaesthesia I-gel was inserted. After proper placement . ventilating bougie was inserted. Once it's placement is confirmed I-gel was removed keeping the ventilating bougie in situ. Then appropriate sized endotracheal tube was railroaded over ventilating bougie then it (v.bouggie) was removed . Proper placement of endotracheal tube was confirmed by bilateral equal chest excursion and air entry on auscultation, absence of gastric insuffflation sound over epigastrium and 'sine' wave on capnography. Maximum 3 attempts were allowed for I-gel, ventilating bougie and endotracheal tube.
DEVICETracheal Intubation using C-LMA and ventilating bougie
Following general anaesthesia C-LMA was inserted. After proper placement of C-LMA, ventilating bougie was inserted. It's placement was confirmed and C-LMA was removed after deflation of cuff keeping the ventilating bougie in situ. Then appropriate sized endotracheal tube was railroaded over ventilating bougie. It's placement was confirmed by bilateral equal air entry and chest excursion, absence of gastric insufflation sound over epigastrium and 'sine' wave on capnography. Maximum 3 attempts were allowed for C-LMA , ventilating bougie and endotracheal tube.
