There have been many reports stating that halperidol premedication has been used for sefative and antiemetic effects. Therefore we utilized haloperidol as a premedicant for the purpose of obtaining the above effects. Over a period of one year from march 1978 to February 1979, 0.1mg haloperidol per kilogram of body weight was given to 747 patients. The results were as follows. 1)The extrapyramidal symptioms appeared in children, especially in the 10-year old group. 2) Large doses of haloperidol were more likely to cause to extrapyramidal symptoms than smaller doses(over 0.1mg/kg) 3)The effects of haloperidol lasted for a considerable duration of time after administration, (about 24-48 hous).

Chemotherapy induced nausea and vomiting (CINV) is typically biphasic. The acute phase usually peaks in 5-6 hours after the administration of chemotherapeutic agents and the delayed phase can occur subsequently over 24hours after chemotherapy. Antiemetic therapy is crucial to prevent this unwanted side effect effectively, and NK1 antagonist, 5-HT3 antagonist, corticosteroid are the main player. The combination and dosing is determined by the emetogenicity of the chemotherapeutic agents to be administrated.

In children and adolescents with acute gastroenteritis and other gastrointestinal disease, antiemetics are frequently used. But there are insufficient data about antiemetic use in children, so it should be used carefully. Despite some significant researches, treatment guidelines of ondansetron will be carefully presented through further investigation.

PURPOSE: Data on the efficacy of olanzapine in patients receiving moderately emetogenic chemotherapy (MEC) are limited. This study aimed to evaluate and compare the efficacy of olanzapine versus placebo in controlling nausea and vomiting in patients receiving MEC. MATERIALS AND METHODS: We conducted a randomized, double-blind, placebo-controlled study to determine whether olanzapine can reduce the frequency of chemotherapy-induced nausea and vomiting (CINV) and improve the quality of life (QOL) in patients receiving palonosetron and dexamethasone as prophylaxis for MEC-induced nausea and vomiting. The primary end point was complete response for the acute phase (0-24 hours after chemotherapy). The secondary end points were complete response for the delayed (24-120 hours) and overall phase (0-120 hours), proportion of significant nausea (visual analogue scale ≥ 25 mm), use ofrescue medications, and effect on QOL. RESULTS: Fifty-six patients were randomized to the olanzapine (n=29) and placebo (n=27) groups. Complete response rates were not significantly different between the olanzapine and placebo groups in the acute (96.5% vs. 88.0%, p=0.326), delayed (69.0% vs. 48.0%, p=0.118), and overall phases (69.0% vs. 48.0%, p=0.118). However, the percentage of patients with significant nausea (17.2% vs. 44.0%, p=0.032) and the use of rescue medications (0.03±0.19 vs. 1.88±2.88, p=0.002) were lower in the olanzapine group than in the placebo. Furthermore, the olanzapine group demonstrated better QOL (p=0.015). CONCLUSION: Olanzapine combined with palonosetron and dexamethasone significantly improved QOL and vomiting control among previously untreated patients receiving MEC, although the efficacy was limited to the reduction of the frequency of CINV.

Patients with severe gag reflex (SGR) have difficulty getting the treatment they require in local clinics, and many tend to postpone the start of their treatment. To address this problem, dentists have used behavioral techniques and/or pharmacological techniques for treatment. Among the pharmacological methods available, propofol IV sedation is preferred over general anesthesia because it is a simpler procedure. Propofol in combination with remifentanil is characterized by stable sedative effects and quick recovery, leading to a deep sedation. Remifentanil acts to reduce the pain caused by lipid-soluble propofol on injection. The synergistic effects of propofol-remifentanil include reduction in the total amount of drug required to achieve a desired sedation level and anti-emetic effects. In this case report, we outline how the use of propofol-remifentanil IV sedation enabled us to successfully complete a wide range of dental treatments in a patient with SGR.

BACKGROUND: Postoperative nausea and vomiting (PONV) is a common problem in patients undergoing thyroidectomy. In this study we evaluated the effects of prophylactic dolasetron and/or induction with propofol on PONV. METHODS: Two hundred three patients scheduled thyroidectomy under general anesthesia with sevoflurane were included and were randomly allocated to one of four groups. In control (group C) and dolasetron groups (group D), the patients received thiopental sodium 4-5 mg/kg intravenously for the induction of anesthesia, and the patients in group D received prophylactic intravenous dolasetron 210 microgram/kg. In propofol (group P) and dolasetron + propofol groups (group D + P), the patients received propofol 2 mg/kg intravenously for the induction of anesthesia, and the patients in group D + P received prophylactic intravenous dolasetron 210 microgram/kg. The incidence and severity of PONV, the need for rescue antiemetics, adverse events were assessed during 0 to 1 hour and 1 to 24 hours postoperatively. RESULTS: During the first 24 hours after anesthesia, the incidences of PONV and postoperative vomiting were significantly reduced in group D + P compared with group C (P < 0.05, respectively). There were no significant differences in postoperative nausea, need for rescue antiemetics, severity of PONV, and adverse events of antiemetics among the four groups. CONCLUSIONS: In patients with thyroidectomy, combination of prophylactic dolasetron administration and induction with propofol was found to reduce the incidence of PONV during the first 24 hours after anesthesia, compared with that of routine induction with thiopental sodium.

PURPOSE: Iodine contrast media used in computed tomography (CT) often induces nausea in patients. This study evaluated the prophylactic effect of metoclopramide against nausea induced by intravenous contrast media. METHODS: A prospective, double-blinded, randomized controlled trial was performed in the emergency department of an urban teaching hospital. Adult patients(>15 years old), who required enhanced CT scans, were infused with 52 ml normal saline solution mixed with either 10 mg/2 ml metoclopramide or 2 ml normal saline over 10 minutes prior to the CT scan. After the scan, the patients were asked about nausea. Patients who had any other cause for their nausea or had received metoclopramide prior to the study were excluded. RESULTS: In total, 69 patients were analyzed. The metoclopramide group contained 37 patients, and the placebo group contained 32 patients. Five patients in the placebo group complained of nausea(15.6%), whereas none of the patients in the metoclopramide group experienced nausea (Fisher's exact test, p=0.018). CONCLUSION: Metoclopramide can prevent nausea induced by intravenous iodine contrast media.
