Blood oxygen test may guide fluid therapy in sepsis
NCT ID NCT07516236
First seen Jun 27, 2026 · Last updated Aug 19, 2026 · Updated 2 times
Summary
This study looks at whether measuring oxygen levels in a central vein can help doctors decide if a patient with septic shock needs more fluids. About 115 adults with septic shock will have their oxygen levels checked before and after a fluid challenge. The results will be compared with standard heart ultrasound measurements to see if this simpler test is accurate.

Who is studied
This single-center, prospective, observational study will be conducted in the Intensive Care Unit (ICU) at Menoufia University Hospitals. Adults spontaneously breathing patients with septic shock who undergo a fluid challenge as a part of their hemodynamic management in the first 24 hours will be eligible for enrollment. Ethical approval will be obtained from the ethics committee at the Menoufia Faculty of Medicine, and the study will follow ethical guidelines and secure approval from the Institutional Review Board (IRB). Written informed consent will be obtained from each participant or their legal surrogate before study inclusion.
