Epidural morphine is effective in the treatment of postoperative pain, but side effects, such as nausea, vomiting, pruritus and urinary retention commonly occur. Droperidol is frequently used as an antiemetic to prevent intraoperative and postoperative vomiting. But it has been reported to cause acute extrapyramidal effects including dystonia. We report one case of acute dystonia in young adult following the use of epidural droperidol.

Hysterectomy can lead to various symptoms threatening decent quality of life. As the frequency of hysterectomy increases, there are many patients who want to take oriental medicine treatments for complications. Several clinical studies have reported the effectiveness of oriental medicine treatment for post-hysterectomy complications. Out of these symptoms, postoperative nausea and vomiting (PONV, hereafter) are indicated at about 20-40% of frequency within patients with general anesthesia, and they may occur not only during recovery from operation, but also after discharge. Although the incidence of PONV has decreased now thanks to the usage of antiemetics, PONV still causes some difficulties for patients returning to daily life. This study reports two cases of post-hysterectomy complications such as nausea, dizziness, vomiting, general weakness, and coldness of the limbs, which had good responses to herbal medication and acupuncture.

Background and objective : Postoperative nausea and vomiting(PONV) are frequent complications of general anesthesia in children. High cost and associated side effects of antiemetic drugs, have increased interest in nonpharmacological methods for treatment of PONV. The aim of this study was to report the effect of acupuncture for prevention of PONV in children. Material and Method : Randomized clinical trials retrieved by a search of articles indexed on the Medline and NDSL database. Key words to search were 'PONV', 'POV', 'acupuncture', 'children', 'pediatric'. Results : Eleven articles were selected and six of them showed significant effectiveness of acupuncture in preventing PONV in children. Acupuncture methods were needle acupuncture acupressure, electro-acupuncture, laser acupuncture, acupuncture point injection. The main acupuncture point was P6(Neiguan). Conclusion : The effectiveness of acupuncture for prevention of PONV in children has been shown in some, but not all trials. Further studies are needed.

Background: Catheter-related bladder discomfort (CRBD) has been observed in many patients undergoing a urethral catheterization. CRBD may be so severe that the patients require additional analgesics. Muscarinic receptors are involved in the mechanism of CRBD. The aim of this study is to determine the effects of the antimuscarinic properties of atropine, which is frequently used in current practice on CRBD, by comparing it with sugammadex which has no antimuscarinic effects. Methods: Sixty patients selected for transurethral resection due to bladder tumors were randomized into 2 groups: an atropine group and a sugammadex group, with no antimuscarinic effect. The patients were given rocuronium (0.6 mg/kg) as a neuromuscular-blocker. In addition to the frequency and severity of CRBD postoperatively at 0, 1, 6, 12, and 24 hours, postoperative numeric rating scale (NRS) scores, and postoperative nausea and vomiting were examined. Results: The incidence of CRBD was significantly lower in the atropine group in all postoperative measurements. The score was found to be significantly lower in the atropine group when NRS measurements were performed at all time periods (P < 0.01). There was no difference between the groups in terms of nausea and vomiting (P > 0.05). Conclusions: Atropine is a cheap, easy-to-access, safe-to-use drug for reducing CRBD symptoms, without any observed adverse effects. Since it not only reduces CRBD symptoms but also has a positive effect on postoperative pain, it can be used safely to increase patient comfort in patients receiving general anesthesia and a urinary catheter.

Background: Postoperative nausea and vomiting (PONV) frequently occurs following bimaxillary orthognathic surgeries. Compared to opioids, Nefopam is associated with lower incidences of PONV, and does not induce gastrointestinal tract injury, coagulopathy, nephrotoxicity, or fracture healing dysfunction, which are common side effects of Nonsteroidal anti-inflammatory drugs. We compared nefopam- and fentanyl-induced incidence of PONV in patients with access to patient-controlled analgesia (PCA) following bimaxillary orthognathic surgeries. Methods: Patients undergoing bimaxillary orthognathic surgeries were randomly divided into nefopam and fentanyl groups. Nefopam 120 mg or fentanyl $700{\mu}g$ was mixed with normal saline to a final volume of 120 mL. Patients were given access to nefopam or fentanyl via PCA. Postoperative pain intensity and PONV were measured at 30 minutes and 1 hour after surgery in the recovery room and at 8, 24, 48, and 72 hours after surgery in the ward. The frequency of bolus delivery was compared at each time point. Results: Eighty-nine patients were enrolled in this study, with 48 in the nefopam (N) group and 41 in the fentanyl (F) group. PONV occurred in 13 patients (27.7%) in the N group and 7 patients (17.1%) in the F group at 8 hours post-surgery (P = 0.568), and there were no significant differences between the two groups at any of the time points. VAS scores were $4.4{\pm}2.0$ and $3.7{\pm}1.9$ in the N and F groups, respectively, at 8 hours after surgery (P = 0.122), and cumulative bolus delivery was $10.7{\pm}13.7$ and $8.6{\pm}8.5$, respectively (P = 0.408). There were no significant differences in pain or bolus delivery at any of the remaining time points. Conclusion: Patients who underwent bimaxillary orthognathic surgery and were given nefopam via PCA did not experience a lower rate of PONV compared to those that received fentanyl via PCA. Furthermore, nefopam and fentanyl did not provide significantly different postoperative pain control.

Objective : Postoperative pain is one of the major complaints of patients after lumbar fusion surgery. The authors evaluated the effects of intravenous patient controlled analgesia (IV-PCA) using fentanyl or sufentanil on postoperative pain management and pain-related complications. Methods : Forty-two patients that had undergone surgery with lumbar instrumentation and fusion at single or double levels constituted the study cohort. Patients were equally and randomly allocated to a sufentanil group (group S) or a fentanyl group (group F) for patient controlled analgesia (PCA). Group S received sufentanil at a dose of $4{\mu}g/kg$ IV-PCA and group F received fentanyl $24{\mu}g/kg$ IV-PCA. A numeric rating scale (NRS) of postoperative pain was applied before surgery, and immediately and at 1, 6, and 24 hours (hrs) after surgery. Oswestry disability index (ODI) scores were obtained before surgery and one month after surgery. Opioid-related side effects were also evaluated. Results : No significant intergroup difference was observed in NRS or ODI scores at any of the above-mentioned time points. Side effects were more frequent in group F. More specifically, nausea, vomiting rates were significantly higher (p=0.04), but pruritus, hypotension, and headache rates were non-significantly different in the two groups. Conclusion : Sufentanil displayed no analgesic advantage over fentanyl postoperatively. However, sufentanil should be considerable for patients at high risk of GI issues, because it had lower postoperative nausea and vomiting rates than fentanyl.

The intermittent injection of analgesics is a inadquate method for postoperative pain control. Recently a non-electroic, disposable and portable infusor (Boxter Two Day $Infusor^R$) has been developed which can deliver analgesics with 2 ml/h speed continuousely. The present study examined the effects of three methods of pain management on recovery in 306 patients undergoing elective surgery in Wonkwang University Hospital. Group 1 (n=106) received i.m. $Valentac^R$ on a PRN basis. Group 2 (n=100), initial 2 mg of bolus morphine was followed by 48 mg of continuous infusion. Group 3 (n=100), initial 2 mg of morphine followed by morphine 18 mg-ketorolac 120 mg. We evaluated an analgesic efficacy with NRS (numerical rating scale) at 12, 24, 36, 48, 60 and 72 hours after the operation. The side effects (nausea, vomiting, pruritus, sedation and respiratory depression) were evaluated. In group 1, we asked major concern before operation and efficacy of pain control with pain severity (no pain, mild pain, moderate pain, sever pain). The results were as follows: 1) Major concern before operation is pain (40%). 2) 53% of patients suffered pain in group 1. 3) Morphine and morphine-ketorolac infusion groups were superior to the i. m. ($Valentac^R$) group with respect to postoperative analgesia. 4) In group 3 (morphine-ketorolac), there was no pruritus and mild nausea and vomiting.

Background : This study was designed to evaluate the continuous effects of single intravenous injection of antiemetics on nausea and vomiting during continuous morphine injection for postoperative pain control. Methods : Prior to the study, we divided patients into two major groups according to the type of surgery performed intra-abdominal(Open: O) and non intra-abdominal(Close: C). When patients regained orientation after routine general anesthesia, enflurane-$O_2-N_2O$, we injected bolus dose of morphine and started continuous injection of morphine for postoperative pain control(Group I; Control). After bolus injection and just before continuous injection, we injected single dose of droperidol(Group II) or ondansetron(Group III). Mean arterial blood pressure, heart rate, pain score and symptom-therapy score were checked at 10 minutes, 4, 8, 16, 24, 36 hours after continuous morphine injection. Results : The pain score of group III was lower than group II(10 min.) and group I(24, 36 hours) in the open group. Symptom-therapy score of group III(10 min., 4, 24 hours) and group II(10 min.) were lower than group I in the open group. In the close group, symptom-therapy score of group III(8 hours) was lower than group I. Conclusions : Single intravenous injection of antiemetics have a tendency of lowering symptom-therapy score for 36 hours in spite of their relatively short elimination half-life.

A retrospective study was performed to evaluate the effects, and side effects, of epidural analgesia for postoperative pain relief of 2,381 surgical patients who received general-epidural, or epidural anesthesia only. Anesthesia records, patients charts, and pain control records were reviewed and classified according to: age, sex, body weight, department, operation site, epidural puncture site, degree of pain relief by injection mode & epidural injectate, and side effects(including nausea, vomiting, pruritus, urinary retention and respiratory depression). The results were as follows: 1) From the total of 2,381 patients, there were 1,563(66%) female patients; 1.032(43%) patients were from Obstetrics and Gynecology. 2) Lower abdomen, thorax, lower extremity and upper abdomen in the operation site; and lumbar, upper, lower thoracic in puncture site were order of decreasing frequency. Length of epidural injection for pain relief averaged $1.72{\pm}1.02$ days. 3) Ninety three percent of the patients experienced mild or no pain in the postoperative course. Analgesic quality was not affected by the kind of epidural injectate. 4) Nausea occurred in 3.2% of all patients, vomiting in 1.1%, pruritus 0.9%, urinary retention 0.6%, respiratory depression 0.08%. 5) Frequency of nausea was higher with female patients compared to male patients(p<0.05). 6) Pruritus frequency was higher with male patients than female patients(p<0.05); and more frequent with patients who received epidural injection with morphine than patients who received epidural injection without morphine(p<0.01). 7) Urinary retention was higher in female patients, and more frequent with patients who had received epidural injection with morphine than epidural injection without morphine(p<0.05). 8) There were two cases of respiratory depression. The course of treatment consisted of: cessation of epidural infusion, then administration of oxygen and intravenous naloxone. We conclude that postoperative epidural analgesia with a combination of local anesthetics and opiate is and effective method for postoperative pain relief with low incidence of side effects. However, patients should be carefully evaluated as rare but severe complications of respiratory depression may ensue.

Background: Contraction of anal sphincter muscle produces severe pain in perianal surgery postoperatively. Recent reports have indicated that effective and prolonged pain relief can be obtained by the injection of small doses of morphine into the subarachnoid space. We attempted to use this technique for perianal surgery and investigated postoperative pain control and its side effects. Methods: Forty five patients scheduled for hemorrhoidectomy and anal fistulectomy were studied to determine the minimal effective dose of intrathecal morphine for postoperative analgesia. In order to control the pain, 7 mg of 0.5% hyperbaric bupivacaine with 0.05 mg (group I), 0.1 mg (group II) and 0.15 mg (group III) of morphine hydrochloride was injected with a 25 gauge spinal needle into the subarachnoid space. We estimated the duration of analgesia until the pain score attained to above 3 in 10 cm VAS (visual analogue scale) and incidence of itching, nausea and vomiting by percentage, headache, backpain and respiratory depression by positive and negative. We also checked the time of self-voiding. Results: The mean time of analgesia was $10.3{\pm}1.54$, $19.7{\pm}2.22$ and $20.3{\pm}2.29$ hours in group I, II and III respectively. Urinary retention of group I, II and III after block persisted for an average of $20.3{\pm}2.31$, $21.2{\pm}2.51$ and $23.3{\pm}3.74$ hours. Nausea and vomiting were observed 33%, 53%, 67% and itching was observed 53%, 67%, 80% in group I, II and III respectively and respiratory depression did not occur in all groups. Conclusions: It is not necessary to use more than 0.1mg of intrathecal morphine in perianal surgery because analgesia is not prolonged and side effects are increased.
