Hair restoration surgery isn’t painless, but pain control is much more effective today than even in the recent past. Medical research has improved understanding of nociception – how a sensation of pain is received, transmitted and interpreted by nerves from the site of injury to the spinal cord and the brain. Better understanding has translated into more effective uses of anesthesia.
There is better understanding of the relationship between effective anesthesia and limitation of bleeding or “oozing” during surgery. An inadequately anesthetized, anxious patient may have increases in heart rate and blood pressure that increase risk for bleeding; thus, anesthesia level and physical signs such as heart rate and blood pressure are carefully monitored during surgery.
