BACKGROUND
Intraoperative superior vena cava (SVC) clamping causes hypotension and cerebral congestion. There is no established method for monitoring brain function during cerebral congestion. We encountered a case of cerebral congestion caused by unexpected SVC clamping.
CASE PRESENTATION
A 64-year-old man underwent SVC clamping during lung tumor resection. The entropy and electroencephalogram monitoring values decreased with SVC clamping and increased in response to the release of congestion by phlebotomy and SVC declamping.
CONCLUSIONS
Because entropy sharply reflects brain viability during cerebral congestion, it was considered helpful in evaluation of the monitoring of cerebral congestion.
背景
术中上腔静脉（SVC）钳夹可导致低血压和脑充血。目前尚无在脑充血期间监测脑功能的既定方法。我们遇到了一例因意外的SVC钳夹导致脑充血的病例。
病例介绍
一名64岁男性在肺肿瘤切除术中接受了SVC钳夹。随着SVC钳夹，熵值和脑电图监测值下降，而在通过放血和解除SVC钳夹缓解充血后，这些值升高。
结论
由于熵值能在脑充血期间敏锐地反映脑活力，因此认为其有助于评估脑充血的监测情况。
