Based on the hypothesis that keeping the endotracheal cuff pressure in the optimum range will reduce the incidence of vip, we aimed to compare the Manual (intermittent) measurement method with the Automatic (continuous) measurement method in reducing the incidence of vap.
Ventilator-associated pneumonia (VIP) is a major cause of morbidity and mortality in intensive care patients. Microaspiration of oropharyngeal and gastric secretions contaminated with bacteria is one of the important factors contributing to the formation of VIP. Under- or over-inflation of the endotracheal tube balloon (cuff) can lead to micro-aspiration, VIP development, and tracheal damage. Intermittent (manual) or continuous (automatic) control of the endotracheal tube cuff pressure has been used as a strategy for preventing VIP in recent years. There are few adult studies evaluating the effectiveness of the use of manual and automatic cuff gauges in intensive care patients in preventing the development of VIP. Our study is the first randomized controlled study in the literature to evaluate the effectiveness of two methods in preventing the development of VIP in pediatric intensive care patients. Our study is a randomized controlled single-blind clinical study. It was planned to include patients aged between 1 month and 18 years, who required at least 48 hours of mechanical ventilation. Our exclusion criteria; intubation history in the last 14 days, airway trauma, airway anomaly, tracheotomy, mechanical ventilation for less than 48 hours and immunosuppression. It was planned to include the patients included in the study in the manual or automatic cuff gauge group using a 1:1 randomization table. In the automatic cuff meter group, it was planned to monitor the patients continuously by targeting 20 cmH20 endotracheal tube pressure. It was planned to measure the cuff pressure at 8 hour intervals for the patients in the manual cuff gauge group and to correct the deviations in the pressure. CDC criteria will be used as VIP diagnostic criteria. Patients will be monitored for the development of VIP and complications related to the endotracheal tube (such as stenosis, stridor)
Study Type
OBSERVATIONAL
Enrollment
168
The cuff pressure of the tracheal tube will be monitored every 8 hours in the manual group using a portable manometer. The target endotracheal tube cuff pressure will be 20 cm H2O during the follow-up of patients. Before starting to work, PICU nurses will be given training in recognizing and preventing VAP and using cuff pressure measuring devices. The application period will continue from the day of intubation to extubation or a maximum of 14 days. Study data forms will be filled out by PICU nurses and monitored by physicians. The research group will periodically observe PICU personnel to verify adherence to the protocol. While patients are mechanically ventilated, VIP findings will be routinely screened at each daily visit.
