The importance of peripheral pulses following cardiac surgery

The sudden disappearance of peripheral pulse tracing in the post cardiopulmonary bypass period can be an ominous sign of a catastrophic complication in cardiac surgery. It needs to be recognized at the earliest and immediate action should be taken to avoid serious outcome. Here we have described a case of Bentall’s procedure in which the right radial arterial tracing disappeared about 60 minutes post-operatively due to aortic dissection, but was repaired successfully because of early detection. We conclude that following cardiac surgery, one must closely monitor the peripheral pulses. The decrease in amplitude or disappearance of peripheral pulse should be taken seriously. It should be investigated immediately and prompt treatment should be done to save life.
