Logistic regression analysis for the risk factors of the reflux during enteral nutrition in patients receiving mechanical ventilation / 中国综合临床

ABSTRACT

Objective To study the risk factors for the reflux of enteral nutrition in the mechanical ventilated ( MV) patients. Methods The data of reflux in 79 MV patients fed by enteral nutrition were collected. These patients were consecutively admitted to intensive care unit (ICU) of the Navy General Hospital from Jan. 2009 to Dec. 2010. Patients' performance conditions,patients' body position,location of feeding tube, way of feeding,tracheotomy,drug intervention were recorded. Simple logistic regression was used to analyze all the risk factors, and statistically significant variables were selected and adopted in multivariate and unconditioned Logistic regression analysis. Results The subjects averagely aged (58.6 ± 15. 3)years old,including 44 males and 35 females;with an APACHE Ⅱ score of 18. 1 ±4.0. Univariate analysis showed that age,position,location of feeding tube,way of feeding, tracheotomy et al were all assoctied with reflux. Advanced age( >60 y) ( OR = 4.577,95% CI 1. 459 - 14. 363, P =0. 009) was an independent risk factor for reflux; semisupination at 30° (OR =0.201,95%CI 0.057 -0.708,P = 0.013),nasalenteral tube (OR =0.267,95% CI0.072 -0.993,P = 0.049) ,and tracheotomy (OR = 0.232,95%CI0.070 -0.763,P =0.016) were independent protecting factors for the reflux. Conclusion Advanced age ( > 60 y) is a high risk factor for the MV patients with enteral nutrition;, semisupination at 30° .nasalenteral feeding,tracheotomy are low risk factors for the MV patients with enteral nutrition.
