Correlative factors analysis of gastric content reflux in NICU

Abstract

Objective To investigate the gastric contents reflux occurred in the patients in Neurosurgery Intensive Care Unit (NICU), and to analyze the risk factors of gastric contents reflux and provide basis for timely and effective nursing intervention measures of clinical practice. Methods A total of 47 patients with mechanical ventilation in NICU of some grade A class three hospitals were collected the data such as age, gender, body posture, state of consciousness, gastric retention, diameter of nasogastric tube, the ballonet pressure of artifical airway and also included samples of throat secretion to test pepsin and pH. Results A total of 235 times watched among 47 patients that the incidence rate of gastric contents reflux was 48.1%. The single factor analysis showed that there were significant differences of gastric contents reflux between subgroups of different tube diameter, nasal feeding pump rate, gastric retention, Glasgow score and ballonet pressure (χ2=6.641, 56.615, 142.846, 17.784, 8.620; P<0.05). Further logistic regression analysis indicated that the factors affected gastric contents reflux was nasal feeding pumping rate and gastric retention. Conclusions Gastric contents reflux is a common complication in EN patients in the NICU. According to the Influencing factors, monitoring gastric retention and set proper nasal feeding pump rate is important for continuous nasal feeding patients to reduce gastric contents reflux rate.
