[Evaluation of standard regimen of single shot spinal anesthesia for cesarean section in Japanese parturients].
BACKGROUND
Recently, single shot spinal anesthesia using local anesthetic and opiate has been thought to be an ideal anesthetic method for cesarean section. For single shot spinal anesthesia, it is important to administer appropriate dose of drugs. However, optimal regimen for cesarean section in Japanese parturients has not been well studied.


METHODS
In the present study, the validity of standard regimen of single shot spinal anesthesia for cesarean section was evaluated retrospectively. In the reviewed five month period (from May 2007 to September 2007), there were 183 cases of cesarean section, and single shot spinal was adopted in 144 cases.


RESULTS
All of them were treated by the standard regimen (hyperbalic 0.5% bupivacaine 10 mg, fentanyl 25 microg, and morphine hydrochloride 0.1 mg). Among 144 cases, 139 cases (96.6%) required no additional pain relief until the delivery, and no parturient experienced critical adverse effects such as total spinal anesthesia.


CONCLUSIONS
It is suggested that the studied regimen was valid for most of Japanese parturients.
