[Comparison of radical retropubic prostatectomy under combined lumbar spinal and epidural anesthesia with that under combined general and epidural anesthesia].
OBJECTIVE
To evaluate the efficacy of combined lumbar spinal and epidural (CLSE) anesthesia in retropubic radical prostatectomy.


METHODS
Twenty consecutive patients who underwent radical retropubic prostatectomy by a single surgeon (H.K.) under CLSE anesthesia from July of 2003 to February of 2004 were selected as subjects. They were compared with 20 consecutive patients who underwent radical retropubic prostatectomy performed by the same surgeon under combined general and epidural (CGE) anesthesia from April to December of 2002. Both periods were carefully selected to exclude radical prostatectomies with intraoperative complications to evaluate genuine effects of anesthesia. For lumbar spinal anesthesia, 0.5% hyperbaric bupivacaine hydrochloride or 0.5% hyperbaric tetracaine hydrochloride (dissolved in a 10% glucose solution) was used. An epidural tube was inserted for both lumbar spinal anesthesia and general anesthesia mainly for the purpose of controlling a pain after operation.


RESULTS
Intraoperative blood loss was significantly less in the CLSE anesthesia group compared with CGE anesthesia group (p = 0.024). Postoperative water drinking was started at 0.4 days (average) for CLSE anesthesia and at 1.1 days (average) for CGE anesthesia (p < 0.0001). Postoperative diet was begun at 0.7 days (average) for CLSE anesthesia and at 1.5 days (average) for CGE anesthesia (p < 0.0001). Compared with the CLSE anesthesia group, the mean of the highest intraoperative mean blood pressure was significantly higher in the CGE anesthesia group (p = 0.002).


CONCLUSIONS
Intraoperative blood loss was less, intraoperative change in blood pressure was less and recovery of postoperative intestinal peristalsis was earlier in patients who underwent prostatectomy under CLSE anesthesia than in patients who underwent prostatectomy under CGE anesthesia. We believe that prostatectomy under CLSE anesthesia is more advantageous than prostatectomy under CGE anesthesia.
