To determine the effect of transpyloric (TP) feeding on microaspiration and lung inflammation in ventilated preterm infants.
NCT07017205
The goal of this clinical trial is to learn if a new method for managing breathing tube pressure is better at preventing fluid from leaking into patients' lungs during surgery. It will also check if it causes fewer side effects like a sore throat. The main questions it aims to answer are: Does using a continuous pressure controller reduce fluid leakage past the breathing tube cuff compared to the standard manual method? Does the continuous pressure controller lead to fewer and less severe sore throats and voice changes after surgery? Researchers will compare two groups: Group 1: Patients whose breathing tube cuff pressure is managed with a continuous automatic controller. Group 2: Patients whose breathing tube cuff pressure is managed with the standard manual method. Participants will: Be randomly assigned to one of the two groups before their surgery. Receive a small, safe amount of blue dye in their mouth during the procedure to help measure leakage. Have two small secretion samples collected from their breathing tube during surgery. Be asked about sore throat and voice changes at 1, 2, 3, and 24 hours after the breathing tube is removed.

In modern anesthesia practice, the application of cricoid pressure during intubation is not infrequently used with the goal of preventing gastric-to-pulmonary aspiration. The evidence to support this practice is very scarce, and there have recently been many reports in the literature questioning the safety of cricoid pressure during intubation. Therefore, the goal of this study will be to randomize those at risk for microaspiration to receive cricoid pressure versus no cricoid pressure during intubation. We will specifically exclude those patients thought to be at the highest risk of aspiration (it is considered standard of care to perform cricoid pressure during intubation of this population). We will include those patients with some risk factors for aspiration (it is not considered standard of care to apply cricoid pressure during intubation of this population).
