  Purpose
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

Primary Outcome Measures:
  • Mean arterial blood pressure [ Time Frame: Participants will be followed for the duration of surgery, an expected average of 90 minutes ]
    Non- invasive blood pressure 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:
  • Heart rate [ Time Frame: Participants will be followed for the duration of surgery, an expected average of 90 minutes ]
    Heart rate 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.

  • detection of adverse events [ Time Frame: 30 days ]
    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)

  • Characteristics of sensory block [ Time Frame: Two minutes after injection of local anesthetic until resolution of the block (about 6 hours postoperatively) ]
    A pinprick test is recorded 2 minutes after local anesthetic injection the every 2 minutes for the first 15 minutes then every 10 minutes till the end of operation then every 30 minutes until resolution of the block.

  • Characteristics of motor block [ Time Frame: Two minutes after injection of local anesthetic until resolution of the block (about 6 hours postoperatively) ]
    Modified Bromage scale is recorded 2 minutes after local anesthetic injection the every 2 minutes for the first 15 minutes then every 10 minutes till the end of operation then every 30 minutes until resolution of the block.

  • Time to first analgesic injection [ Time Frame: Every hour postoperatively up to 10 hours. ]
    0-10 visual analogue scale (VAS) (0: no pain at all, 10: maximum imaginable pain).

Arms Assigned Interventions
Experimental: Epidural
epidural anesthesia was administered via a 20-gauge epidural catheter threaded cephalad through an 18 gauge needle identified by the loss of resistance method to air. Bupivacaine 0.5% 5 ml every 5 minutes for T10 sensory level
Device: Epidural (B. Braun)
20-gauge epidural catheter threaded cephalad through an 18 gauge needle identified by the loss of resistance method to air.
Other Name: B. Braun
Active Comparator: Spinal
An18-gauge Tuohy peel-away epidural sheath was introduced into the epidural space by using loss of resistance technique to air. Epidural introducer was removed leaving epidural sheath to be a pathway for Wiley spinal catheter. A flexible, convenience curve 27-gauge atraumatic pencil point tip spinal needle was introduced through the epidural sheath. After CSF flow was confirmed, a 23-gauge flexible cannula was threaded over the spinal needle. Peel-away epidural sheath was removed and flexible cannula was continually advanced over the spinal needle into the intrathecal space cephaled. Bupivacaine 0.5% 0.5 ml every 5 minutes for T10 sensory level.
Device: Spinal (Wiley Spinal Catheter)
The Wiley Spinal® is an innovative Flexible Cannula over Needle designed for convenient intrathecal access. After dural puncture is achieved, an immediate dural seal is created. The flexible cannula is advanced off the needle ensuring cephalad delivery of medication.
Other Name: Wiley Spinal Catheter
