Transdermal scopolamine in prevention of post open prostatectomy bladder contractions

In a prospective randomized double-blind study among 50 males undergoing surgery we evaluated the possible role of transdermally applied scopolamine (Scopoderm) in the prevention of post open prostatectomy bladder contraction and pain. Patients were evaluated by subjective report of their pain, urination sensation while having indwelling catheter, amount of narcotic administration, and bladder pressure measurements. No significant differences were noted with regard to the occurrence of pain or overall analgesia requirements. However, on postoperative day 2, a significant decrease in analgesia requirements was found among the treated patients. We suggest that the use of Scopoderm may lead to a reduced demand for narcotics by patients from postoperative day 2 onward.
