Comparison of Modified Broselow Tape and Cole Formula

Study Overview
=================
Brief Summary
-----------------
This study aimed to determine the accuracy of modified Broselow tape measurements compared to Cole formula in predicting the size of uncuffed endotracheal tubes in Indonesian pediatrics

Detailed Description
-----------------
110 subjects were given informed consent before enrolling the study and randomized into two groups, modified Broselow Tape and Cole formula. Preoperatively, prediction of suitable ETT size was performed based on Cole formula and Modified Broselow Tape. In the operating theatre, general anesthesia induction was performed with sevoflurane 4-8 vol%, fentanyl 2 μcg/kg BW, and atracurium 0.5 mg/kg BW. Laryngoscopy was performed, and an uncuffed polyvinyl chloride endotracheal tubes, whose size was based on the Cole formula, was inserted. An appropriate size of the endotracheal tube was confirmed if the endotracheal tube could go through the cricoid ring smoothly, and no air leakage found when ventilating with an inspiratory pressure of 15-20 cmH2O. The surgery and anesthesia would proceed if the correct size of the endotracheal tube were successfully inserted. If the tube couldn't pass the cricoid smoothly or air leakage was found when ventilated with an inspiratory pressure of 15-20 cmH2O, the endotracheal tube should be replaced with a bigger or smaller size.
