Background and Objective: Supraglottic Airway Laryngopharyngeal Tube (S.A.L.T) is a new airway gadget conceived as an effective device to facilitate blind oro-tracheal intubation. Literature review showed no available clinical study on human subjects. The aim of our study was to evaluate S.A.L.T as an adjunct to blind oro-tracheal intubation.
Methods: Study design: Single centre, Single group, Open label, Prospective, Interventional pilot study. Study Group: 30 adult patients of either sex belonging to ASA I and II, scheduled for elective surgery under General anaesthesia. Patients were pre-medicated with inj. Glycopyrrolate 0.2 mg and inj. Midazolam 2 mg and induced with Inj. Propofol 2 mg/kg IV. After inj. Suxamethonium 1.5 mg/kg IV, S.A.L.T was inserted and a size 7.0 ID cuffed ETT was inserted through it immediately. The time period, from insertion of the S.A.L.T to the insertion of the ETT was noted. A successful intubation was defined as to insert SALT and intubate through it within 2 minutes irrespective of the number of attempts. Airway trauma, if any was recorded.
Results: Only 40% of the patients were successfully intubated [(20.4% to 59.6% with 95% confidence interval (CI)]. The mean number of attempts required for intubation was 1.4 ± 0.67 (CI - 0.99 to 1.8) and the mean time for intubation was 26.3 ± 19.0 seconds (CI - 14.3 to 38.4 sec). Mallampati class I had more success rate than class III (P < 0.05). No airway trauma was recorded.
Conclusion: S.A.L.T shows limited usefulness as an adjunct for aided blind oro-tracheal intubation.
