The Use of Nasogastric Tube Bridle Kits in COVID-19 Intensive Care Unit Patients

ABSTRACT

Objective: To ascertain the extent of nasogastric tube (NGT) dislodgment in COVID-19 intensive care unit (ICU) patients after the introduction of NGT bridle kits as a standard of practice, to see whether this would reduce the number of NGT insertions, patient irradiation, missed feeds, and overall cost. Background: Nasogastric feeding is the mainstay of enteral feeding for ICU patients. The usual standard of practice is to secure the tube using adhesive tape. Studies show this method has a 40% to 48% dislodgment rate. The COVID-19 ICU patient population may be at even greater risk due to the need for proning, long duration of invasive ventilation, and emergence delirium. Design: This was a 2-cycle quality improvement project. The first cycle was done retrospectively, looking at the contemporaneous standard of practice where bridle kits were not used. This gave an objective measure of the extent of NGT displacement, associated costs, and missed feeds. The second cycle was carried out prospectively, with the use of NGT bridle kits as the new standard of practice. Setting: A large United Kingdom teaching hospital with a 100-bed, single-floor ICU. Participants: Patients admitted to the ICU with COVID-19 who subsequently required sedation and invasive ventilation. Measurements Measurements included days of feeding required, hours of feeding missed due to NGT dislodgment, total number of nasogastric tubes required per ICU stay, and number of chest radiographs for NGT position confirmation. NGT-related pressure sores were also recorded. Results: When compared to the bridled group, the unbridled group required a higher number of NGTs (2.5 vs 1.3;P< .001) and chest radiographs (3.4 vs 1.6;P< .001), had more hours of feeding missed (11.8 vs 5.0), and accumulated a slightly higher total cost (cost of NGT, chest radiographs +/- bridle kit £211.67 vs £210, [US $284.25 vs US $282.01]). Conclusions: The use of NGT bridle kits reduces the number of NGT insertions patients require and subsequently reduces the number of chest radiographs for each patient. These patients also miss fewer feeds, with no appreciable increase in cost.
