Abstract: (438 Views)
Background & Aim: Increased intra-abdominal pressure, which is often hidden in the evaluating of patients, causes critical and complete-rest patients with irreparable consequences. Numerous and consecutive position changes can be effective in creating conditions to increase intra-abdominal pressure. The present study aimed to investigate the effect of position changes on intra-abdominal pressure in mechanically ventilated patients.
Materials & Methods: The present study was a clinical trial in which 68 patients were randomly selected and enrolled. Intra-abdominal pressure was measured by intrablader method using water manometer. Other hemodynamic and respiratory parameters were measured by BENNETT 840 ventilator and SAADAT hemodynamic monitoring device. Data were entered into a checklist and analyzed using SPSS software version 22 and parametric and non-parametric statistical tests. In this study, a significance level of P < 0.05 was considered significant.
Results: The mean intra-abdominal pressure of patients in different conditions had statistically significant differences. Patients in the 15° and 45° positions had the lowest and in the 30° position to the right side, the patients had the highest intra-abdominal pressure (P<0.001). Mean arterial pressure and abdominal perfusion pressure were the lowest in the position of 30° to the right side, and the highest values were in the position of 15° and 45°. The highest values of airway pressure were observed in the position of 30° to the right side.
Conclusion: Changing of position for mechanically ventilated patients in Intensive Care Units can be associated with significant respiratory and hemodynamic consequences.
