Effect of intravenous lignocaine in preventing post operative sorethroat, an intervention study

Completed

Conditions: Medical and Surgical, (2) ICD-10 Condition: O||Medical and Surgical,

Brief Summary: Sore throat after tracheal intubation has been one of the most common postoperative discomforts causing dissatisfaction among the patients. Incidence of post operative sore throat (POST) varies from 30% to 70%.1

Reason behind this is the irritation and inflammation of the airway caused by pressure exerted on the tracheal wall by the endotracheal tube (ETT) inserted during intubation,2 trauma/erosion during intubation and mucosal dehydration.3 Whilst medical staff may concentrate on avoiding problems during surgery, patients will only be aware of postoperative complications whether its minor or the major. Such complications might affect their satisfaction with treatment. Diameter and the pressure of cuff may also influence the prevalence and severity of postoperative sore throat.4

Many non-pharmacological such as laryngeal mask usage had been tried but when the ETT is the only choice in the patients, pharmacological measures to alleviate the incidence and severity of POST with variable success will be taken into consideration.4,5 Many research articles have been mentioned about the prophylactic use of lidocaine, dexamethasone and steroids or the combination of these drugs has been used for this purpose.6,7 Whereas the studies to analyse the efficacy of peri operative intravenous lignocaine are very less. Hence, we would like to conduct a prospective observational study in this regard.
