Brief Summary

This is a prospective observational study to compare ultrasonography, capnography and clinical methods for confirmation of correct endotracheal tube placement in patients undergoing elective surgeries under general anaesthesia. Adult patients aged eighteen to sixty five years belonging to American Society of Anaesthesiologists physical status class one and two will be enrolled. After routine endotracheal intubation, tube position will be assessed using clinical examination, capnography and ultrasonography. The primary outcome will be accuracy, rapidity and reliability of each method in confirming correct tube placement. The study aims to identify the most efficient and reliable method for confirmation of endotracheal intubation in elective surgical patients.
