Endotracheal Tube Cuff Inflation By 4% Lignocaine, Saline and Air: A Comparative Study
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2018, Vol 6, Issue 6
Abstract
Abstract: Laryngoscopy and endotracheal intubation are inevitable before undertaking any major operations or for long term intubation. They are often beset with noxious pathological consequences, such as hoarseness of voice, sore throat, cough, pain etc. Inflation of endotracheal tube cuff with air or saline helps in securing leak less snug fit in the trachea, but of late, there are few reports of the use of Lidocaine as an inflation agent. It is of interest to study the general incidence of post-extubation complications as also whether the choice of Lidocaine makes any difference to the known morbidities of endotracheal intubation. This was a randomized controlled prospective study consisting of 90 patients (ASA I and II) who were allocated into group A (4 % Lidocaine), group B (Normal Saline) and group C (Air). Patients were premeditated with Midazolam 0.03 mg/kg I.V. and Inj Glycopyrrolate 0.005mg/kg. All patients were induced with Thiopentone (4 mg/kg), Suxamethonium (1.5 mg/kg) followed by intubation with appropriate size cuffed oral (portex tube) endotracheal tube. The study period extended upto 48 hours post-extubation. Apart from routine hemodynamic monitoring, post-extubation complications like- hoarseness of voice, sore throat, cough, pain, dysphonia were also compared. The mean values of heart rate, systolic blood pressure, diastolic blood pressure, oxygen saturation for all the groups were comparable and statistically insignificant. One patient developed hoarseness of voice ( Gp A). 8 patients developed sore throat lasted 48 hrs in 4 patients (Gp B). 22 patients developed pain in the throat (9 patients in Group A, 6 patients in Group B and 7 patients in Group C). 23 patients experienced cough (11 patients in Group A; 8 patients in Group B and 4 patients in Group C).
