Background: The aim of this study was to evaluate the preventive effect of propofol on postoperative nausea and vomiting (PONV) following general anesthesia to the patients having oral and maxillofacial surgery. Methods: In a prospective, randomized. case-controlled study. 200 patients were divided into two groups (n = 100 in each). In propofol (P) group, patients received 0.5 mg/kg of propofol intravenously at the end of anesthesia. In control (C) group, no antiemetics was given. Emetic symptoms like nausea, retching and vomiting were assessed by a blind nurse at 1 hour and at 24 hours after anesthesia respectively. Also level of sedation was checked by a blind anesthesiologist at 1 hour after anesthesia. Results: There were no significant differences in frequencies of nausea, retching and vomiting between C group and P group at 1 hour after anesthesia. However, nausea, retching and vomiting were all decreased in P group compared with C group at 24 hours after anesthesia (P < 0.05). Also there was no significant difference in level of sedation at 1 hour after anesthesia between C group and P group (P > 0.05). Conclusions: From the results, prophylactic use of subhypnotic dose of propofol could be effective for preventing PONV without change in level of sedation to the patients undergoing general anesthesia for oral and maxillofaical surgery.

Background: To determine the effectiveness of continuous epidural infusion of droperidol, combined with epidural morphine, in reducing nausea or vomiting associated with epidural morphine and minimizing the side effects of droperidol, 48 patients undergoing elective thoracic surgery were randomly assigned to one of two study groups. Methods: Patients received continuous infusion of epidural morphine(6.0 mg/day) following a bolus loading dose of 3.0 mg(Group A), or epidural mixture of morphine(6.0 mg/day) plus droperidol(5.0 mg/day) following a bolus loading dose(morphine 3.0mg, droperidol 1.5 mg)(Group B). For the first 48 postoperative hours, the incidence of nausea or vomiting, the need for antiemetic therapy, level of sedation, and adverse effects associated with droperidol were evaluated. Results: The incidence of nausea or vomiting and the number of patients who required antiemetic therapy were significantly less in Group B than in Group A(P<0.05). There were no significant differences between groups with regard to the adverse effects associated with droperidol such as mental depression, respiratory depression and abnormal movements(P=NS). Conclusion: We conclude that simultaneous titration of morphine and droperidol via epidural continuous infusion following epidural bolus injection of the mixture reduces nausea or vomiting associated with epidural morphine while it prevents the side effects of droperidol.

Background: The aim of our study was to evaluate the antiemetic effects of intravenous dexamethasone in preventing continuously infused epidural morphine-related nausea and vomiting. Methods: Twenty-seven patients requiring general anesthesia for gastrectomy were enrolled in a randomized, double-blinded, and placebo-controlled study. At the end of surgery, all patients received epidural morphine 3 mg and were connected to an epidural morphine infusion pump for 2 days in order to relieve postoperative pain. Before the morphine injection, the dexamethasone group (n = 12) received IV dexamethasone 10 mg, whereas the saline group (n = 15) received IV saline. The incidence of nausea & vomiting, pruritus, back pain and VAS scores were assessed in the recovery room, and at 24 h and 48 h postoperatively. Results: There was no significant difference in the total incidence of nausea and vomiting, pruritus, back pain or in the VAS scores. However, there was no vomiting and no back pain in the dexamethasone group. Conclusions: Intravenous dexamethasone did not significantly decrease the total incidence of nausea or vomiting in patients receiving continuous epidural morphine for postoperative pain control. However, IV dexamethasone appears to decrease the severity of nausea, vomiting and back pain.

Purpose: This study was done to evaluate the combination effects of capsicum plaster at the Korean hand acupuncture points K-D2 with prophylactic antiemetic on Postoperative Nausea and Vomiting (PONV). Methods: An experimental research design (a randomized, a double-blinded, and a placebo-control procedure) was used. The participants were female patients undergoing gynecologic laparoscopy; the control group (n=34) received intravenous prophylactic ramosetron 0.3mg, while the experimental group (n=34) had Korean Hand Therapy additionally. In the experimental group, capsicum plaster was applied at K-D2 of both 2nd and 4th fingers by means of Korean Hand Therapy for a period of 30 minutes before the induction of anesthesia and removed 8 hours after the laparoscopy. Results: The occurrence of nausea, nausea intensity and need for rescue with antiemetic in the experimental group was significantly less than in the control group 2 hours after surgery. Conclusion: Results of the study show capsicum plaster at K-D2 is an effective method for reducing PONV in spite of the low occurrence of PONV because of the prophylactic antiemetic medication.

There is growing interest in the use of nonpharmacologic approaches to prevent postoperative nausea and vomiting. This study was designed to investigate the effect of acupuncture on P6 for preventing Opioid-induced nausea and vomiting. A total of 83 patients receiving intravenous patient controlled analgesia(PCA) with fentanyl were randomly assigned to two groups. In acupuncture group, they've got treatment after surgery at recovery room for 20minutes. Assessment of nausea and vomiting was obtained from all patients for 48hours. The incidence of nausea, that of vomiting and the nausea grade-the severity of nausea within 48 hours after surgery- were the main outcome measures which showed no statistically significant difference between groups. There is no sufficient evidence to suggest effect of acupuncture on P6 for preventing PONV.

Background: Postoperative nausea and vomiting (PONV), postanesthetic shivering and pain are common postoperative patient complaints that can result in adverse physical and psychological outcomes. Some antiemetics are reported to be effective in the management of postoperative pain and shivering, as well as PONV. We evaluated the efficacy of dexamethasone added to ramosetron on PONV, shivering and pain after thyroid surgery. Methods: One hundred and eight patients scheduled for thyroid surgery were randomly allocated to three different groups: the control group (group C, n = 36), the ramosetron group (group R, n = 36), or the ramosetron plus dexamethasone group (group RD, n = 36). The patients were treated intravenously with 1 and 2 ml of 0.9% NaCl (group C); or 2 ml of 0.15 mg/ml ramosetron plus 1 ml of 0.9% NaCl (group R); or 2 ml of 0.15 mg/ml ramosetron plus 1 ml of 5 mg/ml dexamethasone (group RD) immediately after anesthesia. Results: Incidence of nausea and the need for rescue antiemetics, verbal rating scale (VRS) 1 hour pain value, ketorolac consumption, and incidence of shivering were significantly lower in group R and group RD, than in group C (P < 0.05). Moreover, these parameters were significantly lower in group RD than in group R (P < 0.05). Conclusions: Combination of ramosetron and dexamethasone significantly reduced not only the incidence of nausea and need for rescue antiemetics, but also the VRS 1 hour pain value, ketorolac consumption, and the incidence of shivering compared to ramosetron alone in patients undergoing thyroid surgery.

Background: To date, there are no controlled studies assessing the effect of metoclopramide administered epidurally to prevent nausea and vomiting associated with epidural morphine for postoperative analgesia. This study was undertaken to determine the effectiveness of continuous epidural infusion of metoclopramide, combined with epidural morphine, in reducing nausea or vomiting associated with epidural morphine and minimizing the side effects of metoclopramide. Methods: Sixty patients undergoing elective gynecologic surgery were randomly assigned to one of two study groups. Patients received continuous epidural morphine infusion (6.0 mg/day) following a bolus loading dose of 3.0 mg (Group A), or epidural mixture of morphine (6.0 mg/day) plus metoclopramide (20 mg/day) following a bolus loading dose (morphine 3.0 mg, metoclopramide 10 mg)(Group B). For the first 24 postoperative hours, incidence of nausea or vomiting, need for antiemetic therapy, level of sedation, degree of pain and pruritus, and adverse effects associated with metoclopramide were evaluated. Result: Incidence of nausea or vomiting and number of patients who required antiemetic therapy were significantly less in Group B, than in Group A (P<0.05). There were no significant differences between groups with regard to adverse effects associated with metoclopramide such as sedation, extrapyramidal reaction and other side effects (P=NS). Conclusion: We conclude simultaneous titration of morphine and metoclopramide via epidural continuous infusion following epidural bolus injection of the mixture reduces nausea or vomiting associated with epidural morphine while preventing side effects of metoclopramide.

Objective : This prospective, randomized, double-blinded trial aimed to evaluate the efficacy and safety of prophylactic ramosetron administration against postoperative nausea and vomiting (PONV) in patients undergoing microvascular decompression (MVD). Methods : In this study, 100 patients undergoing MVD were randomly allocated to the control (normal saline, 2 mL) or ramosetron (ramosetron, 0.3 mg) groups at the end of surgery. The incidence and severity of PONV, need for rescue antiemetics, patient satisfaction score, duration of hospital stay, and the occurrence of adverse events were evaluated 48 hours post-surgery. Results : Data obtained from 97 patients were included in the final analysis. The incidence of PONV was significantly lower in the ramosetron group than in the control group throughout the 48-hour postoperative period (29.2% vs. 51.0%, p=0.028). A similar trend was observed with regard to PONV severity (p=0.041). The need for rescue antiemetics, satisfaction score, duration of hospital stays, and the occurrence of adverse events did not significantly differ between the groups. Conclusion : Prophylactic ramosetron administration reduced the incidence and severity of PONV in patients undergoing MVD without causing serious adverse events. Thus, ramosetron use may improve patient recovery following MVD.

Purpose: Postoperative nausea and vomiting(PONV) is a common problem after general anesthesia. The aim of this prospective, double-blind randomized study was to compare the effect of Propofol-Remifentanil vs. Sevoflurane inhalational anesthetics on PONV after laparoscopic cholecystectomy. Methods: Forty patients (ASA physical status 1, 2) scheduled for elective surgery participated in the study. Twenty of them received total intravenous anesthesia (TIVA group) with Propofol-Remifentanil, and the rest were given Sevoflurane inhalational anesthetics (inhalation group). The TIVA group was induced with Propofol 5mcg/ml and Remifentanil 3~4mcg/ml. The anesthesia was maintained with the continuous infusion of Propofol 2~3mcg/ml and Remifentanil 2~3mcg/ml IV. The inhalation group was induced with Pentotal Sodium 5mg/kg and 3~4mcg/kg/hr IV Remifentanil. Maintenance was obtained with 1.5~2.0 vol% Sevoflurane. Results: The subjects in TIVA group reported less PONV than those in Sevoflurane inhalation anesthesia group. Conclusion: Propofol-Remifentanil anesthesia (TIVA group) was considered a satisfactory anesthetic technique in reducing PONV in patients with laparoscopic cholecystectomy.

Purpose: Postoperative nausea and vomiting (PONV) is very common among postoperative orthopedic surgical patients with patient-controlled analgesia (PCA), especially for narcotics. Therefore, the purpose of this study was to investigate the effects of an evidence-based PONV management protocol on nursing and patient outcomes. Methods: A methodological study was conducted to develop PONV protocol and a quasi-experimental study to evaluate the effectiveness of protocol. The preliminary PONV protocol was drawn by conducting a systematic review and by reviewing clinical guidelines and best practice recommendations. Validation of the content was done by expert clinicians, and the clinical applicability was evaluated by staff nurses and patients. The effect was evaluated in clinical outcomes associated with PONV and nursing outcomes. Results: In the experimental group, the occurrence of vomiting (z= 2.147) was significantly decreased, the maintenance PCA (${\chi}^2=4.212$) and the satisfaction of patients (z= 5.007) were significantly higher. In the outcomes of nurses, the PONV knowledge of nursing care (z = 3.791), awareness (z = 2.982) and self-efficacy (z= 2.745) were higher in the experimental group. The attitude towards evidence-based nursing practice (z= 2.446) was significantly positive. Conclusion: The results show that an evidence-based approach to the implementation of PONV care is effective in improving patient clinical outcomes and quality of care.
