Refractory hypotension due to intraoperative hypothermia during spinal instrumentation

Refractory intraoperative hypotension with elevated serum tryptase

Severe intraoperative hypotension has been reported in patients on angiotensin-converting enzyme inhibitors and angiotensin II receptor subtype 1 antagonists. We describe a patient on lisinopril who developed refractory intraoperative hypotension associated with increased serum tryptase level suggesting mast cell activation (allergic reaction). However, allergology workup ruled out an allergic ...

Vasopressin for refractory hypotension during cardiopulmonary bypass.

Methods to prevent intraoperative hypothermia.

Inadvertent intraoperative hypothermia is by far the most commonly occurring anaesthesia-related complication. It can increase the risk of unfavourable events perioperatively. Higher rates of surgical site infections and blood transfusions, coagulation and drug metabolism disturbances are said to be the most relevant issues linked to this phenomenon. Although they have been available for severa...

Spinal Hemangiopericytoma Which Needed Intraoperative Embolization due to Unexpected Bleeding

Spinal intradural hemangiopericytoma is a very rare tumor and can be characterized by massive bleeding during surgeries, frequent recurrence, and metastasis. However, definite radiologic differential points of hemangiopericytoma are not known. We describe an unexpected hemangiopericytoma case with large bleeding and management of the tumor. A 21-year-old man visited complaining of progressive n...

Intraoperative pulmonary embolism during spinal instrumentation surgery. A prospective study using transoesophageal echocardiography.

Intraoperative pulmonary fat and bone-marrow embolism is a serious complication of bone and joint surgery. We have investigated the occurrence and incidence of intraoperative embolism in patients undergoing elective lumbar spinal surgery with or without instrumentation. Sixty adult patients with lumbar degenerative disease were examined by intraoperative transoesophageal echocardiography while ...
