A Comparative Study On Effect Of Tracheal Tube Cuffsfilled With Air Versus Alkalinized Lidocaine On Hemodynamic Response Changes During Extubation And Postoperative Laryngotrachial Morbidities In Childrens.

INTRODUCTION: When the lateral pressure exerted by an inflated cuff on tracheal mucosarnexceeds capillary perfusion pressure, it can result in tracheal morbidity, loss of mucosal cilia,rnulceration, hemorrhage, and tracheal stenosis. Patients may complain of cough, sore throat andrnhoarseness in the postoperative period. Lidocaine within tracheal tube cuffs seems to exert arnlocalized effect on the trachea after diffusing through the cuff, resulting in improved tolerance torntracheal. Both alkalinized and non-alkalinized lidocaine used to fill tracheal tube cuffs reducesrnthe incidence of postoperative sore throat. rnOBJECTIVE: was to assess the effectiveness of tracheal tube cuffs filled with air versesrnalkalinized lidocaine on heamodynamic response changes and laryngotracheal trachealrnmorbidities during and post extubation in children’s. rnMETHODOLOGY: Institutional based observational prospective cohort study design used tornaddress the study objective. All elective children aged 3-13 years who undergoing operationrnunder general anesthesia with endotracheal intubation greater than one hour at TASH werernselected. The outcome variable ware Haemodynamic response changes i.e. (HR,SBP and DBP),rnwas measured in the 5 min before, and 5 min following, tracheal extubation and laryngotrachealrnmorbidities like cough, hoarsens and sore throat, evaluated as dichotomous variables (yes or no). rnRESULTS: Hemodynamic changes that recorded during the study were the highest systolic andrndiastolic blood pressure and the heart rate. The results shows the heat rate difference of p valuern
