BACKGROUND: The combination of epidural opioids and local anesthetics provides synergistic analgesia and appears to provide superior analgesia with activity. But the effects of both drugs on bowel motility are oppositional. The object of this study is to evaluate the effect of combined epidural-general anesthesia and postoperative epidural analgesia on the recovery of bowel function and on complications in colon surgery. METHODS: 84 patients were allocated to three groups. 29 patients received intraoperative epidural- general anesthesia and continuous epidural analgesia with local anesthetic-opioid for 48 hours postoperatively (Group I). Group II (n = 25) and Group III (n = 30) received intraoperative general anesthesia alone with postoperative epidural analgesia with an intramuscular injection of analgesics, respectively. We compared the pain score and side effects of these analgesic methods, recovery of bowel movements, postoperative complications and postoperative hospital stay among groups. RESULTS: Groups I and II showed better analgesic effects at rest and upon coughing when compared with Group III (P<0.05). There were no significant differences in the incidences of nausea and vomiting, pruritus, motor blockade and the recovery time of bowel movement and postoperative hospital stay among groups. The incidences of ileus/wound complication and dysrhythmia were not different, but the incidence of pulmonary complication in group I (0%) was significantly lower than in group II (12%) and III (20%) (P<0.05). CONCLUSIONS: Combined epidural-general anesthesia and postoperative epidural analgesia results in decreases in the pain score and in the incidence of pulmonary complication. Moreover, epidural analgesia using local anesthetic and opioid does not affect side effects, recovery time of bowel motility, incidences of ileus/wound and dysrhythmia complications.

BACKGROUND: Ultrafiltration is a method to reduce capillary leak and the accumulation of extravascular water associated with cardiopulmonary bypass(CPB). There are two techniques of ultrafiltration, conventional and modified techniques. The effect of the former is controversial. The author investigated the effect of ultrafiltration performed in pediatric open heart surgery in our institute. METHODS: The retrospective study was done in 18 children who received surgical correction of congenital heart disease associated with left to right shunt. Eight children undergone ultrafiltration(UF group) were compared with 10 children who did not receive ultrafiltration(non-UF group). Ultrafiltration was performed mainly during rewarming of CPB(conventional UF) with or without modified technique for about 5 minutes immediately after bypass. Hematocrit(Hct), mean arterial pressure(MAP) and platelet count, 24-h blood loss, the amount of transfusion, fluid requirement, time to extubation, duration of ICU stay and the postoperative hospital stay were compared between groups. RESULTS: The volume of ultrafiltrate was 149+/-88 ml and ultrafiltrate/total blood volume(UF/TBV) ratio was 8.6+/-5.3%. The increase of Hct(5.4+/-1.7%) and of MAP(14+/-5.9 mmHg) after rewarming in UF group were significantly greater than 1.5+/-1.7% and 4+/-8.9 mmHg in non-UF group, respectively(p <0.05). There were no significant differences in platelet count, 24-h blood loss, the amount of transfusion, fluid requirement, maximum body temperature, time to extubation, duration of ICU stay and the postoperative hospital stay between groups. CONCLUSIONS: Ultrafiltration performed during open heart surgery in children significantly increases Hct and MAP immediately after ultrafiltration, but does not affect 24-h blood loss, the time to extubation, duration of ICU stay and the postoperative hospital stay.

The malignant fibrous histiocytoma (MFH) was first introduced in 1963 to refer to a group of soft-issue tumors characterized by a storiform or cartwheel-ike growth pattern and predominantly fibroblastic appearance. It was postulated that they were derived from histiocytes that could assume the appearance and function of fibroblasts. MFH has been recognized to be the most common sarcoma in the soft tissue of late adult life which involves the deep fascia or skeletal muscles of the extremities or retroperitoneum. It has been noted in other organs, however, it rarely arises in the liver. We report two cases of primary malignant fibrous histiocytoma of the liver histopathologically confirmed after surgical resection-storiform pleomorphic and myxoid subtypes in the 55 year old male and 49 year old female patients, respectively, and describes the clinical courses, characteristics and pathologic aspects with review of the related literatures.

BACKGROUND: The purpose is to determine the efficacy of additional intravenous patient-controlled analgesia (IV-PCA) by comparing the analgesic effects between interscalene block (ISB) combined with IV-PCA and single ISB after arthroscopic shoulder surgery. METHODS: A total of 213 patients who underwent arthroscopic shoulder surgery were divided into two groups based on the type of perioperative anesthesia. The single ISB group included 100 patients, while the IV-PCA group included 113 patients. The visual analogue scale for pain (VAS pain) scores were assessed at 12, 24, and 48 hours postoperatively in accordance with shoulder pathology. Postoperative narcotics-related complications and consumption of additional non-steroidal anti-inflammatory drugs between the two groups were compared. RESULTS: VAS pain showed no significant difference between the two groups at most points of the postoperative timeline, regardless of shoulder pathology, except in patients with rotator cuff repair at postoperative 24 hours. Although the IV-PCA group showed a statistically lower VAS pain score than the ISB group at postoperative 24 hours (p=0.04), the difference in the VAS pain score was only 9.0 mm in patients with rotator cuff repair. Narcotics-related complications were observed more frequently in the IV-PCA group than in the ISB group for patients with rotator cuff repair. CONCLUSIONS: Additional IV-PCA demonstrated no booster effect for immediate pain control in patients undergoing arthroscopic shoulder surgery with preoperative single ISB. Furthermore, patients with IV-PCA experienced greater narcotics-related complications.

BACKGROUND: Intradermal test is a useful diagnostic method for acute anaphylactoid or anaphylactic reactions induced by anesthetic drugs. We analyzed the responses of intradermal test for anesthetic drugs in patients who did not show anaphylactoid or anaphylactic reactions. METHODS: The authors performed intradermal test for anesthetic drugs (thiopental, midazolam, fentanyl, atracurium and vecuronium) in 224 adult patients one hour before induction of anesthesia. The responses were interpreted as measuring the size of wheal and flare. We also did history taking for past allergic history. RESULTS: There were no patient that showed positive reaction. The rate of false positive reaction for atracurium (12.5%) was significantly higher than other anesthetic drugs (p<0.05). And the rate of false positive reaction for atracurium in patients under the age of 40 (20%) was significantly higher than those above the age of 40 (3.8%) (p<0.05). But the difference of the rate of false positive reaction for atracurium between male (8%) and female (15.3%) was not significant statistically. The differences of the rates of false positive reaction for anesthetic drugs between past allergic history group and no past allergic history group were not statistically significant. CONCLUSIONS: In intradermal test for anesthetic drugs, the rate of false positive reaction for atracurium was significantly higher than thiopental, vecuronium, fentanyl and midazolam. Especially, it was significantly higher in patients under the age of 40. So in performing intradermal test to search for causative anesthetic drug, we have to consider the high rate of false positive reaction for atracurium.

The Laugier-Hunziker syndrome is a rare syndrome characterized by macular hyperpigmentation of the lips and buccal mucosa associated with melanonychia. Onset is usually in adult life and no consistent systemic associations have been reported. Here we report a 39-year-old wonam with a longitudinal pigmented band on a finger and pigmented macules on the lip. We suggest that this is the first report in Korea and the syndrome is presumably more common than recognized.

BACKGROUND: Interactions between nimodipine, a calcium channel blocker, used perioperatively for the treatment of subarachnoid hemorrhage, and vecuronium, rocuronium, and atracurium were studied with phrenic nerve-hemidiaphragm preparations of rats. METHODS: Male 200-300 g Sprague-Dawley rats were randomly allocated into four groups (control, NMD(5), NMD(50) and NMD(500) group, n = 10, respectively) according to the nimodipine concentration, and three groups (control, NMD(2D) and NMD(7D), n = 10, respectively) according to the pretreatment duration. A square wave 0.1 Hz supramaximal stimuli was applied to the phrenic nerve-hemidiaphragm preparation and the twitch height response was recorded with mechanomyography. The dose-response curves were measured, and ED(5), ED(50), ED(90), and ED(95) of each vecuronium, rocuronium, and atracurium in different concentrations of nimodipine of 5, 50, and 500 ng/ml and rocuronium in pretreatment with nimodipine 2.5 mg/kg/d for 2 and 7 days were calculated using an inhibitory sigmoid Emax model. RESULTS: The dose-response curves of rocuronium and atracurium were significantly shifted to the left in NMD(500) group, and significantly shifted to the right in NMD(7D) group (P < 0.05). In NMD(500) group, ED(50), ED(90), and ED(95) of rocuronium and atracurium were significantly reduced, and those of rocuronium in NMD7D group were significantly increased compared with the control group (P < 0.05). CONCLUSIONS: Nimodipine 500 ng/ml in the phrenic nerve-hemidiaphragm preparation of rat increased sensitivity to rocuronium and atracurium, and the dose-response curve was significantly shifted to the left, but following pretreatment for 7 days, nimodipine decreased the potency of rocuronium, and the dose-response curve was significantly shifted to the right.
