The minimum volume of intraperitoneal fluid that is detectable in Morison's pouch with ultrasound in the trauma setting is not well defined. To evaluate this question, we used diagnostic peritoneal lavage (DPL) as a model for intraperitoneal hemorrhage and undertook a blinded prospective study of the sensitivity of ultrasound in detecting intraperitoneal fluid. Participants included attending physicians and residents in emergency medicine, radiology, and surgery. During the infusion of the DPL fluid, participants continuously scanned Morison's pouch until they detected fluid. All participants were blinded to the rate of infusion and the volume infused. One hundred patients were entered into the study. The mean volume of fluid detected was 619 mL. Only 10% of participants detected fluid volumes less than 400 mL and the overall sensitivity at one liter was 97%. We conclude that reliable detection of intraperitoneal fluid in Morison's pouch requires a greater volume than has been previously described.
在创伤情况下，超声检查能在莫里森隐窝检测到的腹腔内液体的最小体积尚无明确界定。为评估这一问题，我们将诊断性腹腔灌洗（DPL）作为腹腔内出血的模型，并对超声检测腹腔内液体的敏感性进行了一项盲法前瞻性研究。参与者包括急诊医学、放射学和外科的主治医师及住院医师。在输注DPL液体期间，参与者持续扫描莫里森隐窝，直至检测到液体。所有参与者均不知晓输注速率和输注体积。100名患者纳入本研究。检测到的液体平均体积为619毫升。只有10%的参与者检测到体积小于400毫升的液体，一升时的总体敏感性为97%。我们得出结论，要可靠检测莫里森隐窝内的腹腔内液体，所需的液体体积比先前描述的要大。
