| description | Study objective: To evaluate the effect of the Trendelenburg position on oxygen transport in hypovolemic patients.
Design: A prospective, self-controlled sequential design.
Interventions: All patients had indwelling pulmonary artery catheters, and hypovolemia was confirmed by a pulmonary artery wedge pressure of 6 mm Hg or less. Hemodynamic and oxygen transport variables were measured with the patient supine and again ten minutes after placing the patient in the Trendelenburg position.
Setting: University-affiliated tertiary care surgical ICU.
Type of participants: Eight postoperative adults.
Results: Mean arterial blood pressure increased from 64.9±4.9 to 75.6±3.5 mm Hg (P |

Setting: University-affiliated tertiary care surgical ICU.
Type of participants: Eight postoperative adults.
Results: Mean arterial blood pressure increased from 64.9±4.9 to 75.6±3.5 mm Hg (P<.05), pulmonary artery wedge pressure increased from 4.6±1.1 to 7.9±0.8 mm Hg (P<.05), and the systemic vascular resistance rose to 2,965±210 from 2,302±199 dyne·sec/cm5 (P<.05). There was no significant change in cardiac index, oxygen delivery, oxygen consumption, or oxygen extraction ratio.
Conclusion: The increase in blood pressure from Trendelenburg position is not associated with an improvement in blood flow or tissue oxygenation.</description><identifier>ISSN: 0196-0644</identifier><identifier>EISSN: 1097-6760</identifier><identifier>DOI: 10.1016/S0196-0644(94)70079-6</identifier><identifier>PMID: 8135435</identifier><identifier>CODEN: AEMED3</identifier><language>eng</language><publisher>New York, NY: Elsevier Inc</publisher><subject>Adult ; Aged ; Anesthesia.
