Purpose: The purpose of this study was to investigate the effect of dehydration from preoperative fasting on postoperative nausea and vomiting in patients who underwent gynecologic surgeries. Methods: Study design was a prospective descriptive study. A total of 75 patients in a university hospital were selected. Data were collected from March 17 to May 16, 2014 using self-report questionnaires and clinical electronic chart. Results: Factors influencing the development of postoperative nausea and vomiting were type of surgery (t=3.44, p=.001), use of PCA (t=-2.16, p=.034), and preoperative dehydration level (t=5.93, p<.001), and these variables accounted for 51.7% of postoperative nausea and vomiting. Among these variables, preoperative dehydration amount (${\beta}=.56$) showed the largest influence in the difference in postoperative nausea and vomiting. Conclusion: Reducing dehydration during preoperative fasting can prevent occurrence of postoperative nausea and vomiting. Development of a clinical guideline is necessary to give directions for the prevention of dehydration during preoperative fasting and to ensure the proper duration of fasting according to patient characteristics, type of surgery and time of surgery.

Purpose: The purpose of the study was to evaluate the effects of postoperative oral care using cold therapy on nausea, vomiting and oral discomfort after laparoscopic myomectomy. Method: The study was conducted with an experimental group (n=29) and a control group (n=35) sampled from patients admitted to a women's hospital in a metropolitan city in Korea. Data were collected between October 10, 2011 and January 31, 2012 and analyzed using Chi-square, Fisher's exact test, t-test, and repeated measure ANCOVA with SPSS/WIN 19.0. Results: After the intervention, postoperative nausea (p<.001) and oral discomfort for patients in the experimental group were significantly lower than in the control group. There were significant differences in the presence of vomiting between both groups at 12 hours (p<.001) and 24 hours (p=.003) after leaving the recovery room. Conclusion: Oral care using cold therapy was found to be an effective nursing intervention for reducing postoperative nausea, vomiting and oral discomfort up to 24 hours after recovery in patients with laparoscopic myomectomy.

Purpose: The purpose of this study was to compare desflurane anesthesia with desflurane-remifentanil anesthesia by measuring postoperative pain, nausea and vomiting after gynecologic laparoscopic surgery. Methods: Data were collected using a random double blind method. The experimental group treated with desflurane-remifentanil anesthesia had a total of 25 patients. The control group had 20 patients who were treated with desflurane anesthesia. Pain (VAS), pushing PCA button, nausea and vomiting (VAS) were assessed at PACU (Post Anesthesia Care Unit) arrival, 10 min, 20 min, 30 min in PACU and 2 hrs, 6 hrs, 24 hrs, 48 hrs in ward. INVR was assessed at 24 hrs. Extra analgesics and extra antiemetics were measured in PACU and the ward. Data were analyzed using t-test and repeated measure using ANOVA. Results: The experimental group presented with more postoperative pain (F=7.55, p<.001) than the control group. The experimental group took more extra analgesics in PACU and pressed the PCA button more often for 6 hours. The experimental group complained more postoperative nausea (F=2.11, p=.043) than the control group and took extra antiemetics during postoperative period of 24 hours. Conclusion: We conclude that desflurane-remifentanil anesthesia needs better management than desflurane anesthesia due to increased pain, nausea & vomiting after gynecologic laparoscopic surgery.

Purpose: The purpose of this study was to compare the effects of ondansetron combined with dexamethasone on Post-Operative Nausea and Vomiting (PONV) and pain with ondansetron alone in patients with laparoscopy assisted vaginal hysterectomy under general anesthesia. Methods: Data were collected from April 1 through September 30, 2005 using a double blind method. Ondansetron 4 mg and dexamethasone 10 mg were administered to the experimental group (25 patients), and ondansetron 4 mg only to the control group (25 patients). The medications were administered through an intravenous line at the beginning peritoneum suture. PONV by Index of Nausea Vomiting and Retching (INVR), nausea by Visual Analogue Scale (VAS), and pain (VAS) were assessed at postoperative 1 hr, 3 hr, 6 hr, 24 hr, and 48 hr. Data were analyzed using repeated measures ANOVA, and Bonferroni methods. Results: The experimental group that received ondansetron combined with dexamethasone had less PONV (p=.048), and nausea (p=.012) than control group that received ondansetron alone. However, there was no difference in pain (p=.557) between the patients in the two groups. Conclusion: We conclude that the administration of ondansetron combined with dexamethasone is more effective than the administration of ondansetron alone to reduce PONV in patients with laparoscopic hysterectomy.

Epidural morphine provides excellent analgesia for the management of postoperative pain, but nausea and vomiting are a commonly reported side effect. Scopolamine, a belladona alkaloid, is an effective antiemetic when nausea is induced by morphine. Transdermal scopolamine patches have the advantage of delivering a constant low dosage of the drug over a prolonged period. To evaluate the efficacy of prophylacitic transdermal scopolamine in reducing nausea or vomiting associated with postoperative epidural morphine analgesia, I studied 60 healthy adult patients. The patients were divided into 3 groups, each group consisting of 20 patients. Group 1; no scopolamine for control Group 2; transdermal scopolamine placebo patch Group 3; transdermal scopolamine patch All patients were anesthetized by epidural injection of 2% lidocaine 15 ml and 0.5% bupivacaine 10 ml with morphine 4 mg. A Comparison with the control group, the placebo group, and Group 3, indicated, that the transdermal scopolamine reduced the incidence of nausea or vomiting associated with postoperative epidural morphine analgesia (group 1; 35%, group 2; 25%, group 3; 10%). However there were no statistically significant differences between groups at a level of p>0.05.

Background: Ondansetron is both a central and peripheral serotonin (5HT) receptor antagonist and droperidol is a dopaminergic blocking drug which acts centrally at the chemoreceptor trigger zone. We assessed the efficacy and adverse effects of ondansetron, droperidol or both, in the prevention of postoperative emesis during postoperative intravenous patient-controlled analgesia (PCA) using butorphanol and ketorolac medication. Methods: We studied 60 women, aged 25-60 yrs, who underwent total abdominal hysterectomy (TAH), under general anesthesia using $N_2O-O_2$-enflurane. A bolus dose of 1 mg of butorphanol and 4 mg of ondansetron were given to patients and thereafter, PCA was started using 10 mg of butorphanol and 240 mg of ketorolac mixed into the 5% D/W solution (total volume; 100 ml, 1 ml of bolus dose, and 10 min of lockout interval). We also added ondansetron 4 mg (Group O, n = 20), ondansetron 4 mg and droperidol 2.5 mg (Group OD, n = 20), or droperidol 2.5 mg (Group D, n = 20) to the PCA drug. The severity of pain, nausea, vomiting, sedation and other side effects were assessed at 0, 1, 2, 6, 12, 24, 36 and 48 hr after awakening. Results: There was no difference in the incidence of nausea and vomiting between the three group [Group O: 4 (20%) and 3 (15%), respectively; Group OD: 1 (5%) and 1 (5%), respectively; Group D: 3 (15%) and 3 (15%), respectively]. Group O showed a lower sedation score than the other groups (P < 0.05). The pain score and other side effects did not show any difference between the groups. Conclusions: The combination of ondansetron and droperidol showed no clinical benefit compared with ondansetron or droperidol alone for prevention of postoperative nausea and vomiting during postoperative PCA using butorphanol and ketorolac.

Purpose: The purpose of this study was to examine the effects of the evidence-based clinical practice guidelines on Postoperative Nausea and Vomiting (PONV). Methods: The research design was a non-equivalent control group with a non-synchronized design. The participants were the patients undergoing gynecologic laparoscopy. Data were collected from July, 2014 through January, 2015. The participants in the experimental group (n=35) received an assessment of risk factors of PONV, aroma therapy, and P6 acupressure method as recommended in the guidelines. Those in the control group (n=35) received usual nursing care. Data were analyzed by mean, standard deviation, t-test, ${\chi}^2$-test using SPSS/WIN 19.0 program. Results: The occurrence of nausea and vomiting, the level of nausea and vomiting, and the need for antiemetic medicine in the experimental group were significantly less than those in the control group after surgery. The levels of postoperative pain and the amounts of time for nursing activities in the experimental group were significantly reduced than those in the control group after surgery. The levels of satisfaction were significantly higher in the experiment group than that of the control group. Conclusion: The evidence-based guidelines is recommended for nursing practice as a guidance for managing PONV and helping the recovery of patients after laparoscopic surgery.

Background: There are no controlled studies assessing the effect of metoclopramide and droperidol administered epidurally for the prevention of nausea and vomiting associated with epidural morphine. This study was undertaken to compare the effectiveness of continuous epidural metoclopramide and droperidol in reducing nausea and vomiting associated with epidural morphine. Methods: Ninty patients undergoing elective gynecologic surgery were randomly assigned to one of three study groups; Group A(n=30) patients received continuous infusion of epidural morphine(6.0 mg/day) following a bolus loading dose of 3.0 mg; Group B(n=30), epidural mixture of morphine and droperidol(5.0 mg/day) following a bolus loading dose(morphine 3.0 mg, droperidol 1.5 mg); Group C, (n=30), epidural mixture of morphine and metoclopramide(20 mg/day) following a bolus loading dose(morphine 3.0 mg, metoclopramide 10 mg). For the 24 postoperative hours, the incidence of nausea and vomiting, degree of pain, level of sedation and other adverse effects were evaluated. Results: Incidence of nausea and vomiting, and number of patients who required antiemetic therapy were significantly less in Group B and C than in Group A(P<0.05). Patients in Group A and C were less sedated than those in Group B. Conclusions: We conclude metoclopramide is more effective than droperidol for postoperative nausea and vomiting due to its lower of sedative effect.

Background: The aim of this study was to evaluate aprepitant in combination with palonosetron as compared to palonosetron alone for the prevention of postoperative nausea and vomiting (PONV) in female patients receiving fentanyl-based intravenous patient-controlled analgesia (IV-PCA). Methods: In this randomized single-blinded study, 100 female patients scheduled for elective surgery under general anesthesia were randomized to two groups: Group AP (80 mg aprepitant plus 0.075 mg palonosetron, n = 50) and Group P (0.075 mg palonosetron, n = 50). The patients in group AP received 80 mg aprepitant per oral 1-3 h before surgery, while all patients received 0.075 mg palonosetron after induction of standardized anesthesia. All patients had postoperative access to fentanyl-based IV-PCA. The incidence of nausea and vomiting, use of rescue medication, and severity of nausea were evaluated at 6 and 24 h after surgery. Results: The incidence of nausea (54%) and vomiting (2%) in group AP did not differ significantly from that in group P (48% and 14%, respectively) during the first 24 h after surgery (P > 0.05). Patient requirements for rescue medication in group AP (29%) were similar to those in group P (32%) at 24 h after surgery (P > 0.05). There was no difference between the groups in severity of nausea during the first 24 h after surgery (P > 0.05). Conclusions: Aprepitant combined with palonosetron did not reduce the incidence of PONV as compared to palonosetron alone within 24 h of surgery in women receiving fentanyl-based IV-PCA.

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.
