Intubation by anesthesia colleagues and sterile draping. Subsequent reopening of the cutaneous and subcutaneous suture. Aspiration of the hematoma. Overall, there is diffuse bleeding in several places and a minimal vascular stump cranial to the paralaryngeal omohyoid muscle. This is ligated, but then breaks off; it can no longer be found during the dissection, but this site is extensively coagulated and no further bleeding occurs centrally. Other sites are also extensively bipolar coagulated. Overall, no large or medium-sized vessel can be identified that could have caused the bleeding. Repeated irrigation with Ringer's and finally also with H2O2, again no relevant bleeding, not even after raising the systolic blood pressure above 120 mmHg. Therefore, another Redon insertion, subcutaneous and skin sutures with 4.0 Vicryl and 4.0 Ethilon. Enorally dry conditions, therefore termination of the operation. Note: At the beginning of the operation, the patient again received 7 ampoules of Minirin and 1 platelet concentrate intraoperatively. He also received 1000 mg tranexamic acid. Tranexamic acid 1000 mg please 3 times daily, BGA check in intensive care unit. Minirin 7 ampoules every 12 hours. Before the next administration, please check the PFA and platelet aggregation in the laboratory and consult the transfusion medicine colleagues again tomorrow. The patient goes to the intensive care unit intubated and ventilated.
