ABSTRACT

Aim: To investigate the effect of residual gastric volumes in intensive care patients on the incidence of ventilator-associated pneumonia. Study Design: Randomized controlled trial Place and Duration of Study: Department of Medicine, Department of Medicine, Chandka Medical College Hospital, Larkana from 1st July 2019 to 31st December 2019. Methodology: One hundred patients were enrolled in the study in both genders admitted to ICU. After having given written consent, patients received comprehensive information, such as age, sex, body mass index and medical history. GRV was measured every 3 hours and GRV>250 cc gastric intolerance was described. Vomiting and VAP occurrence, GRV, mechanical ventilation time and ICU remainder, APACHE II and SOFA rates and death rate were observers. Results: The mean APACHEII and SOFA scores, ICU length of stay, and duration of mechanical ventilation in the GRV>250ml group were significantly higher than in the GRV≤250 ml group. No significant difference was observed regarding VAP between GRV>250ml group and GRV <250ml group, p-value >0.05. Infection, vomiting and mortality rate was high in patients with GRV >250ml as compared to patients with <250ml with p-value <0.05.

Conclusion: No significant difference was observed regarding VAP incidence between patients with GRV >250ml and GRV <250ml. However, infection, vomiting and mortality rate was high in patients with GRV >250ml.
