Background: Microvascular decompression with retromastoid craniotomy carries an especially high risk of postoperative nausea and vomiting. In this study, we compare the antiemetic efficacy of ramosetron and ondansetron in patients undergoing microvascular decompression with retromastoid craniotomy. Methods: Using balanced anesthesia with sevoflurane and remifentanil infusion, ondansetron 8 mg (group O, n = 31) or ramosetron 0.3 mg (group R, n = 31) was administered at the dural closure. The incidence and severity of postoperative nausea and vomiting, required rescue medications and the incidence of side effects were measured at post-anesthetic care unit, 6, 24 and 48 hours postoperatively. Independent t-tests and the chi-square test or Fisher’s exact test were used for statistical analyses. Results: There were no differences in the demographic data between groups, except for a slightly longer anesthetic duration of group R (P = 0.01). The overall postoperative 48 hour incidences of nausea and vomiting were 93.6 and 61.3% (group O), and 87.1 and 51.6% (group R), respectively. Patients in group R showed a less severe degree of nausea (P = 0.02) and a lower incidence of dizziness (P = 0.04) between 6 and 24 hours. Conclusions: The preventive efficacy of ramosetron when used for postoperative nausea and vomiting was similar to that of ondansetron up to 48 hours after surgery in patients undergoing microvascular decompression with retromastoid craniotomy. A larger randomized controlled trial is needed to confirm our findings.

Remote cerebellar hemorrhage after unruptured cerebral aneurysm surgery -two cases report-
하상희,김은미,주향미,이우경,민경태 대한마취통증의학회 2014 Korean Journal of Anesthesiology Vol.67 No.3
Remote cerebellar hemorrhage (RCH) occurring distant to the site of original surgery, such as supratentorial or spinal surgery, is rare but potentially fatal. Because the pathophysiology of RCH is thought to be excessive cerebrospinal fluid drainage during the perioperative periods, its diagnosis usually depends on the occurrence of unexpected neurologic disturbances and/or postoperative brain computerized tomography imaging. Because of its rarity, RCH-associated neurologic disturbances such as delayed awakening or nausea and vomiting may often be misdiagnosed as the effects of residual anesthetics or the effect of postoperative analgesic agents unless radiologic images are taken. Treatment for RCH ranges from conservative treatment to decompressive craniectomy, with prognoses ranging from complete resolution to fatality. Here, we report two cases of RCH after surgical clipping of an unruptured cerebral aneurysm of the anterior communicating artery and review anesthetic considerations.

Purpose: This study was to evaluate the characteristics of selective spinal anesthesiausing 1 mg of bupivacaine combined with fentanyl or sufentanil in elderly patientsundergoing transurethral resection of prostate. Materials and Methods: Fifty-six patients were randomized into two groups. The Fentanyl group received 0.5% hyperbaric bupivacaine 0.2 mL+fentanyl 20 μg+5% dextrose 1.4 mL, and the Sufentanil group received 0.5% hyperbaric bupivacaine 0.2 mL+sufentanil 5 μg+5% dextrose 1.7 mL intrathecally. Intraoperative and postoperative characteristicswere evaluated. Patient satisfaction was assessed postoperatively. Results: Twenty-six patients in each group completed the study. The median peak sensory block level was similar between two groups, but sensory regression time was longerin the Sufentanil group than the Fentanyl group (p=0.017). All patients were able to move themselves to the bed without any aid when they arrived at the admissionroom. Pain scores were lower in the Sufentanil group than the Fentanyl group at postoperative 6, 12, and 18 hours (p=0.001). Compared to the Fentanyl group, the Sufentanil group required less postoperative analgesia (p=0.023) and the time to the first analgesic request was longer (p=0.025). Twenty-four of 26 patients(92.3%) in each group showed “good” satisfaction level. Conclusion: Selectivespinal anesthesia using 1 mg of bupivacaine with fentanyl or sufentanil providedappropriate sensory block level with spared motor function for transurethral resection of the prostate in elderly patients. Intrathecal sufentanil was superior to fentanyl in postoperative analgesic quality.
