Geriatric patients have a significantly higher incidence of morbidity and morality during surgery compared with younger age group. Transurethral resection of the prostate (TURP) is the gold standard treatment for elderly patients with bladder outlet obstruction. Thus Regional techniques may be better tolerated in the elderly patients undergoing TURP having the advantages of minimizing blood loss and thromboembolic events. The Wiley Spinal™ (Epimed; Johnstown, NY) catheter is an innovative flexible cannula over needle designed for convenient intrathecal access that reduces PDPH. We hypothesized that using less anesthetics during continuous spinal anesthesia with the Wiley spinal catheter would offer more hemodynamic stability with less side effects when compared with continuous epidural anesthesia in patients undergoing TURP

Further study details as provided by Theodor Bilharz Research Institute:

Primary Outcome Measures:
  • Systolic blood pressure [ Time Frame: Participants will be followed for the duration of surgery, an expected average of 90 minutes ] [ Designated as safety issue: Yes ]
    Non- invasive blood pressure, heart rate and pulse oximetry will be recorded before administering anesthesia, immediately after placing the catheter, every 1min for the first 10 min, then every 5 min till end of the operation.

Secondary Outcome Measures:
  • detection of adverse events [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
    failure of regional anesthesia (unilateral or patchy block), pruritus, dizziness, nausea, vomiting, itching, PDPH and symptoms suggestive of neurologic damage (back pain, numbness, weakness or pain in legs, and bladder or bowel dysfunction)

Enrollment: 30
