Patients were assigned a sequential number that was placed in an opaque, sealed envelope by the researcher. Information of allocation was available to the principal researcher only. Two-group pre-test and repeated post-test studyĬomputer generated randomization (was used to randomly assign patients to one of both groups. Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information Baseline ventilation and oxygenation parameters were assessed immediately before positioning then it was reassessed every 10 minutes after positioning for 30 minutes. Patients were maintained in the study positions for 2 hours each time. Patients were positioned in the study positions 4 times per day. One hundred and ten adult mechanically ventilated patients with body mass index ≥ 30 were randomly assigned by a computer program to either reverse Trendelenburg position group (n=55) which is the intervention group or semi-recumbent position group (n=55) which is the routine unit position. This trial was conducted in four general intensive care unit of Alexandria Main University hospital in Alexandria, Egypt. Reverse Trendelenburg position is recommended for obese patients but in critical illness with mechanical ventilation little is known about its effect on respiratory therapeutic targets. It is also associated with mechanical ventilation success or failure and may be a main determinant of the obese patients' outcome. Obese critically ill patients' position significantly impacts on their ventilation and oxygenation status. Why Should I Register and Submit Results?.
