Perioperative monitoring of the electrocardiogram during cerebral aneurysm surgery.
Electrocardiographic (ECG) abnormalities occur frequently following a subarachnoid hemorrhage and may also occur intraoperatively and postoperatively in patients undergoing neurovascular procedures. The aim of this study was to assess the relationship between ECG changes and the neurological status of the patient, the size and the location of the aneurysm, and the influence of these changes on the cardiac and neurological outcome. The preoperative ECG was analyzed in 270 patients. ⋯ Intraoperative and postoperative changes occurred in 35 and 65% of the patients, respectively, and were independent of the studied factors. There were no documented cardiac events. The presence of an abnormal preoperative ECG did not influence the neurological outcome of the patient, but fluctuating postoperative changes were associated with a worse outcome.
