Dear Peter, I went through hernia repair last December & it was no fun for me. I had it done under general anesthhetic which I thought [erroneously] wouuld be better than local / spinal tap etc. I also took Eldepryl up to an hour before surgery. Operation was done as outpatient surgery. I was slow to come out of anesthesia. I came out very "off." as respects PD. Whole digestive system shut down and would not respond to various laxatives. Magnesium Citrate i.e., dynamite of sorts had no effect. Five days at home with lpn nurse very much needed. Then a fainting spell & woke up on floor. Back to hospital as inpatient for three days. ADVICE: Get together with anesthesiologist and decide upon least likely scenario to avoid ileus. Do not wait till day before operation! Do it now. If possible avoid Fentanyl. Definitely avoid meperidine. Go easy on other opiates such as Oxycodone. We Parkies cannot tolerate dopamine antagonists. Realize that opiates and dopamine go for about the same set of receptors. After the operation figure on taking it easy for a while. I was led to believe that I would be virtually recovered in a few days. Give yourself time! Good luck..... I had oral surgery last month & made sure of anesthetics.... no problems. Will Johnston in Salisbury, Maryland
