There is also the possibility of complications. Not so long ago, a close friend died as the result of an infection acquired during a routine, elective, surgical procedure. The episode lingers like a bright-red warning light. Other psychological issues crop up during the recovery period. When we're healthy, we tend to think of our bodies as somehow intact, both inviolable and homogene-ous.
Major surgery can shatter that image, and with it the concept of self-sustaining health.
The feelings of mortality, of loss, and of vulnerability can be profound, and recognizing depression in surgery's aftermath becomes very important. Depressed patients have a significantly higher rate of complications. If you're not able to participate in rehabilitation, if you're not as active, the whole process of recovery just slows down. Delirium is another condition that can occur during the one or two days immediately following surgery, especially among older people. Doctors recognize what's happening when patients become incoherent, disoriented, or hallucinatory.
