This position, through the use of gravity, provides the surgical team with access to the patient’s abdominal organs by moving other organs in the abdominal cavity away from the surgical site. Hold this position for three seconds and slowly lower back down. Introducing pauses for positioning checks and relieving Trendelenburg for even brief periods of time can reduce the risk for the most common injuries sustained while patients are in this position.4. This facilitates respiration, and alleviates regurgitation problems and acid reflux. The Trendelenburg position may help alleviate menstrual cramps.

Because gravity’s can be effectively reversed relative to the body, the Trendelenburg position is also useful in assisting with the placement of central venous catheters in the internal jugular or subclavian veins, due to the veins filling and distending. Second timeouts involving checking patient positioning and making adjustments based on the patient physiological and physical status have been proposed for cases taking longer than 4 hours.

This study evaluated the effect on the retinal structure and function in patients undergoing RALP. Reverse Trendelenburg Positioning; Reverse Trendelenburg Positioning. To determine whether the 15-degree reverse Trendelenburg position (RTP) during functional endoscopic sinus surgery improves endoscopic field of view and reduces intraoperative blood loss when compared with the horizontal position (HP). Compression devices and anti-embolism stockings should be used to prevent pooling of blood in the legs. The results obtained in this study show that reverse Trendelenburg position (RTP) can reduce patients’ back pain after cardiovascular angiography and interventions, the degree of back pain scores in the experimental group was less than in the … The mean CSA at 15° reverse Trendelenburg was 0.83 cm 2 (SD, 0.86), in the supine position it was 1.25 cm 2 (SD, 0.98), and at −15° Trendelenburg it was 1.47 cm 2 (SD, 1.03).

Reverse Trendelenburg position decreased central venous pressure without significantly decreasing the systolic blood pressure, suggesting that it is possible to perform hepatectomy with reverse Trendelenburg position more safely than with inferior vena cava clamping. Consequently, the diaphragm shifts upward and outward and contributes approximately two-thirds of the ventilator force and significantly decreases tidal volume. Trendelenburg position is typically used for lower abdominal surgeries including colorectal, gynecological, and genitourinary procedures as well as central venous catheter placement. Proper patient positioning depends on the type and length of procedure, anesthesia access to the patient, devices required and other factors. Citing Literature.

Physiologic Mechanisms Associated with the Trendelenburg Position Ostrow et alconducted a similar study on the effects of the Trendelenburg position on hemodynamics in 23 normotensive cardiac surgery patients.5 In this study they found no statistical-ly significant changes in CO, MAP, SVR or tissue oxygenation. … Effects of reverse Trendelenburg position and inguinal compression on femoral vein cross-sectional area in infants and young children E. H. Suk,1 D. H. Kim,4 H. K. Kil2 and T. D. Kweon3 1 Clinical Assistant Professor, Department of Anaesthesiology … The reverse Trendelenburg position, similarly, places the body supine on an incline but with the head now being elevated.
