In radical surgery for ovarian cancer (OC), hypotension that is difficult to correct is usually rare unless there is significant blood loss. We recently encountered a patient who developed persistent and severe hypotension during radical transabdominal OC surgery. A patient was 52 years old with a history of hypertension and well-controlled preoperative blood pressure (BP). A total of 2000 mL of ascites was drained and blood loss was 300 mL when the operation proceeded to 5.5 hours. The patient's cardiopulmonary function and blood gas analysis showed no significant abnormalities. persistent and uncorrectable hypotension. There was no significant edema in the patient's head or face, nor did the surgeon observe noticeable edema in her intestinal walls or other organs. No oozing was seen at the surgical site. Fluid resuscitation and vasopressor administration were continued. As BP control further deteriorated, blood counts, coagulation, and biochemical electrolyte analyses revealed severe hypoalbuminemia (13.5 g/L) and coagulation dysfunction. After intravenous human serum albumin (HSA) and fresh frozen plasma therapy, her hypoalbuminemia and coagulation were gradually corrected. Based on this case, we suggest that in OC patients experiencing mild intraoperative bleeding and minimal heart rate variation but persistent refractory hypotension, hypoalbuminemia should be considered even if preoperative biochemical tests (including serum albumin levels) are normal. Confirming hypoalbuminemia warrants HSA administration to alleviate hypovolemic shock symptoms. Additionally, it is important to be cautious of potential coagulation issues with albumin use, possibly requiring plasma infusion to address coagulopathy.
