A Prospective comparative study of Ultrasonography (USG) tool Vs Capnography and chest auscultation to confirm Endotracheal intubation performed by Anaesthesia residents

The study will be carried out on patients undergoing surgery under General Anaesthesia(GA)and who require Endotracheal intubation a through pre operation check up will be done prior  and on the day of surgery after confirming fasting patients will be taken to operation theatre after the patient enters the operation theatre routine monitors will be attached and patients will be pre oxygenated for 3 minutes and injection Propofol 2mg per kg of patients weight injection Fentanyl 2mcg per kg of patients weight and injection Atracurium 0.5mg per kg of patients weight as loading dose will be used to induce General Anaesthesia and Anaesthesia post graduate residents of first and second year of training will perform endotracheal intubation as the patient is undergoing laryngoscopy the time at which the scope is introduced into the oral cavity the time starts and as the tube enters the vocal cords a Reverberation artifact is seen and this is a sign of endotracheal intubation seen under the guidance of ultrasonography the time of artifact is noted and once the tube is fixed the patient is ventilated through the ventilator where we see the Etco2 readings as wave patterns and as the first wave pattern ends time is noted and six waves patterns are considered as a confirmatory sign  for a successful endotracheal intubation and the time at the end of sixth reading of Etco2 is noted and the bilateral chest auscultation and bilaterally equal air entry concludes another confirmatory sign of successful endotracheal intubation and the time of confirmatory auscultatory sign is noted and time differences are noted and the ultrasonography guided successful endotracheal intubation is proved to be faster than conventional methods
