[Case of traumatically bleeding shock patient rescued by using an aortic occlusion balloon catheter during surgery]

A 55-year-old (163 cm, 70 kg) man with traumatic intra-abdominal bleeding underwent emergency operation. The patient was in a state of hemorrhagic shock with 82 mmHg of systolic blood pressure (SBP) at hospital arrival. His condition became severer within about 1 hr, and tracheal intubation and mechanical ventilation were consequently started in the ambulatory emergency room. SBP decreased to 60 mmHg when he was transferred to the operating room. Anesthesia was induced with intravenous fentanyl and vecuronium, and was maintained with inhalation of sevoflurane in 50% oxygen. After laparotomy, it was impossible to detect the bleeding source because of a large quantity of hemorrhage. To reduce the blood loss, aortic occlusion balloon catheter (AOBC) was inserted into the upper abdominal aorta via the right femoral artery. Aortic occlusion was performed twice each for twenty minutes. The evelation of SBP and decrease of bleeding dose were secured by aortic occlusion. Thereby the source of bleeding could be detected and surgical procedure could be finished with survival of the patient. The insertion of AOBC for the surgical patient with intra-abdominal hemorrhagic shock may be advantageous for uncontrollable bleeding.
