The Relationship Between Hyperglycemia Status and High Gastric Residual Volume Status in Adult ICU Patients

Introduction: Hyperglycemia commonly occurs in critically ill patients due to metabolic stress. Hyperglycemia can cause gastric motility disturbance in which can cause high gastric residual volume (GRV). The objective of this study is to determine the relationship between hyperglycemia and high GRV status in ICU patients. Methods: This study used cross sectional method with consecutive sampling of 96 adult ICU patients. Blood glucose level were measured every 12 hours and GRV every 4 hours on first and second day admission to ICU. Data were analyzed with Statistical Package for Social Science Program (SPSS) version 20.0. The relationship between hyperglycemia status and high GRV status were analyzed using Chi-Square test. Results: Hyperglycemia status was found in 45.8% subjects on day 1 and 35.4% on day 2. High GRV status was found in 28.1% on day 1 and 25% on day 2. There was no significant relationship between hyperglycemia and high GRV status on day 1 and 2 (p=0.34 and 0.81). However, in 12 subjects, we found high GRV occurred 19.67 11.06 hours after the onset of hyperglycemia. Conclusion: There was no significant relationship between hyperglycemia status and high GRV status, but high GRV could be found later after hyperglycemia.
