Comparison of Four Methods for Predicting Endotracheal Tube Size in Pediatric Patients in India

Abstract

Abstract: This study aims to compare the effectiveness of four different methods for predicting endotracheal tube (ETT) size in Indian children. Accurate selection of ETT size is crucial for optimizing ventilation and reducing airway complications. The methods evaluated include the age- based formula, the uncuffed tube size chart, the height-based formula, and the formula derived from the child’s weight. A total of 200 pediatric patients, aged between 1 and 12 years, were included in the study. Each patient's ETT size was predicted using all four methods, followed by the actual size used during anesthesia induction. The results were analyzed to determine the accuracy of each method by comparing predicted sizes with the actual sizes. Preliminary findings indicate that the height-based formula provided the most reliable predictions. This study highlights the need for precise methods to ensure appropriate airway management in pediatric patients. The findings will guide anesthetists in selecting the appropriate ETT size to enhance patient safety and comfort during procedures.
