A Comparative Study Using Four Different Techniques of Nasogastric Tube Insertion in Anaesthetised and Intubated Patients Undergoing Laparoscopic Surgery: a Randomized Controlled Prospective Observational Study

Modified techniques improve first-attempt success compared to the conventional method. Although the slit endotracheal tube achieved the highest success, it was associated with greater trauma and longer insertion time. Guidewire-assisted insertion offered the most balanced profile of success, efficiency and minimal complications, thus making it a reliable alternative.
