Evaluation and Predictors for Nasogastric Tube Associated Pressure Ulcers in Critically Ill Patients

Summary

Background:

Nasal device-related pressure ulcers are scarcely addressed in the literature.

Objective:

To assess the prevalence and severity of cutaneous and mucosal nasogastric tube (NGT)-associated pressure ulcers (PU) in critically ill patients and to define predictors for their formation.

Methods:

A single center observational study of intensive care unit patients with a NGT for more than 48 hours was conducted. Nasal skin was evaluated for PU. Ulcers were graded according to their depth. Consenting patients underwent a nasoendoscopic examination to evaluate intranasal mucosal injury.

Results:

The study comprised 50 patients, 17 of whom underwent nasoendoscopic examination. Mean time of NGT presence in the nose was 11.3 ± 6.17 days. All patients had some degree of extranasal PU, 46% were low grade and 54% were high grade. Predictors for high grade extranasal PU compared to low grade PU were higher peak Sepsis-related Organ Failure Assessment (SOFA) scores (11.52 vs. 8.87, P = 0.009), higher peak C-reactive protein (CRP) levels (265.3 mg/L vs. 207.58, P = 0.008), and bacteremia (33.3% vs. 8.7%, P = 0.037). The columella was the anatomical site most commonly involved and the most severely affected. The number of intranasal findings and their severity were significantly higher in the nasal cavity containing the NGT compared to its contralateral counterpart (P = 0.039 for both).

Conclusions:

NGTs cause injury to nasal skin and mucosa in critically ill patients. Patients with bacteremia, high CRP, and high SOFA scores are at risk for severe ulcers, warranting special monitoring and preventive measures.
