Does intra-cuff alkalinized lidocaine prevent tracheal tube induced emergence phenomena in children?

To study and investigate the efficacy of intra-cuff alkalinized lidocaine in the prevention of the endotracheal tube [ETT] induced emergence phenomena in children.Fifty children, ages 6-12 years, ASA physical status I-II, scheduled for elective dental surgery under N2O free general anesthesia with an expected duration of 120 min or more, were randomly assigned one of the two groups [25 patients each]; lidocaine group in which the cuff of ETT was inflated with a mixture of lidocaine 2% and sodium bicarbonate 8.4% and the saline group, in which tube cuff was inflated with 0.9% saline solution.There were significant reduction in the incidence and severity [p=0.005 and p= 0.014] of cough at extubation and in the PACU [P=0.048 and P=0.014]. The incidence and severity of postoperative sore throat was also reduced in the lidocaine group compared to the saline group [p=0.025 and 0.031 respectively]. Moreover, there was a significant prolongation of the time to spontaneous ventilation before extubation in the lidocaine compared to the control group [16.4 +/- 3.1 min and 9.4 +/- 1.7 min respectively] with p value < 0.0001. Intra-cuff alkalinized lidocaine reduces the incidence of cough, sore throat, improved ETT tolerance and inducing smooth extubation in paediatric patients, but prolongs time to spontaneous ventilation before extubation

Perianaesthetic blood glucose measurement; evaluation of a rapid method

This study has been planned to evaluate the accuracy of glucometer [Accutrend]. Fourty blood glucose measurements were randomly included in this study. Patients were anaesthetized by different techniques. Blood glucose concentration was measured by both glucometer and the st and ard laboratory glucose-oxidase method [Beckman Autoanalyser]. From the results of this study, blood glucose values measured by glucometer [Accutrend] are always lower than those measured by the st and ard lab glucose oxidase method and the calculated bias value was 17.6 +/- 51.8 and the limits of agreement were wide ranging from 121.2 to -86mg dL-1 which are unaccepted for clinical purposes
