Local active warming: an effective treatment for pain, anxiety and nausea caused by renal colic.

PURPOSE: Based on previous studies showing that warming decreases trauma pain in emergency care we hypothesized that local active warming of the abdomen and lower back region could decrease pain in acute renal colic cases during emergency transport. MATERIALS AND METHODS: After obtaining informed consent 100 patients were divided into 2 groups, including those who received active warming of the abdomen and lower back region (42C) and those who received no warming. Pain, nausea and anxiety were rated by the patients using visual analog scales. Statistical evaluation was performed using the t test with p <0.05 considered significant. RESULTS: In group 1 a significant pain decrease was recorded in all cases using a visual analog score (VAS) (82.7 +/- 9.5 to 36.3 +/- 16.0 mm VAS, p <0.01). In group 2 patient pain scores remained comparable (81.8 +/- 13.0 to 80.6 +/- 12.3 mm VAS). In group 1 anxiety significantly decreased (79.0 +/- 8.9 and 30.7 +/- 14.1 mm VAS before and after treatment, respectively, p <0.01). In group 2 a nonsignificant change in score was noted (79.7 +/- 20.5 to 75.2 +/- 19.7 mm VAS). In group 1 a significant decrease in nausea was recorded in all cases (85.7 +/- 11.2 to 40.6 +/- 23.0 mm VAS, p <0.01). In group 2 patient nausea scores remained comparable (79.2 +/- 22.0 to 80.3 +/- 22.4 mm VAS, respectively). CONCLUSIONS: Local active warming is an effective and easy to learn pain treatment for patients with acute renal colic in emergency care.

Protein-predominant meals inhibit the development of gastric tachyarrhythmia, nausea and the symptoms of motion sickness.

BACKGROUND: Meal ingestion has been suggested to reduce susceptibility to the development of gastric tachyarrhythmia, the abnormal activity of the stomach that frequently accompanies nausea. AIM: To determine the types of meal that are most effective in preventing the development of gastric tachyarrhythmia, nausea and the symptoms of motion sickness provoked by a rotating optokinetic drum. METHOD: Participants received a carbohydrate beverage, a protein-predominant beverage or nothing immediately before exposure to the rotating drum. Subjective symptoms of motion sickness and electrogastrograms were collected during a 6-min baseline period and a subsequent 16-min drum rotation period. RESULTS: Subjective symptoms of motion sickness scores were significantly more severe during the no-meal condition than during either the protein or carbohydrate condition. Central, peripheral and, to some extent, gastrointestinal symptoms were more severe during the carbohydrate condition than during the protein condition. Gastric tachyarrhythmia increased significantly less from baseline to drum rotation during both the protein and carbohydrate conditions than during the no-meal condition. CONCLUSIONS: Liquid protein-predominant meals were most effective in suppressing both the development of gastric tachyarrhythmia and the entire spectrum of motion sickness symptoms, including nausea.

Ondansetron, clinical development for postoperative nausea and vomiting: current studies and future directions.

The clinical development of ondansetron for the prevention and treatment of postoperative nausea and vomiting has been progressing for 5 years, and continues as new directions of research are being addressed. Large multicentre studies have demonstrated the efficacy of ondansetron in the prevention and treatment of postoperative nausea and vomiting, but no large comparator studies have been reported. Several studies are now being undertaken to compare ondansetron with other currently used antiemetics such as droperidol and metoclopramide, assessing efficacy, safety, pharmacoeconomic, and quality of life parameters. The majority of studies to date have been performed in gynaecological surgery patients receiving general anaesthesia--a population that experiences a high incidence of postoperative nausea and vomiting. Clinical development of ondansetron is therefore progressing to establish its efficacy in a wider surgical population, including paediatrics, the elderly, non-gynaecological surgery, and as retreatment in patients with failed prophylactic antiemetic therapy.

Prevention of nausea and vomiting after day case gynaecological laparoscopy. A comparison of ondansetron, droperidol, metoclopramide and placebo.

We have compared the efficacy of ondansetron, metoclopramide, droperidol and placebo in the prevention of postoperative nausea and vomiting in 118 day stay patients undergoing laparoscopic gynaecological procedures. All received a standardised general anaesthetic of fentanyl, propofol, nitrous oxide in oxygen and isoflurane. Three to five min before induction of anaesthesia, patients were allocated to receive ondansetron 4 mg, metoclopramide 10 mg, droperidol 1 mg or placebo in a randomised, double-blind manner. Visual analogue scores for nausea, the incidence of emetic episodes, and analgesic and antiemetic consumption were recorded for 48 h postoperatively. The scores for nausea were significantly lower in the ondansetron group (p < 0.01) compared with the other three groups at 1, 2 and 4 h after operation; thereafter there was no difference. The incidence of emesis was lower (p = 0.063) and time to first oral fluids was shorter (p < 0.05) in the ondansetron group. Oral analgesic requirements were significantly greater in the ondansetron group over the 48 h study period. Two patients, one each in the placebo and metoclopramide groups, had to remain in hospital overnight because of persistent emetic symptoms.

A comparison of droperidol and cyclizine in the prevention of postoperative nausea and vomiting associated with patient-controlled analgesia.

Fifty ASA 1 or 2 patients scheduled to undergo major gynaecological surgery were allocated randomly to one of two groups. All patients received a standard anaesthetic regimen. Patients in group 1 received droperidol 1.25 mg given intravenously 20 min prior to the end of surgery and a patient-controlled analgesia infusion containing morphine 1 mg.ml-1 and droperidol 0.05 mg.ml-1. Patients in group 2 received cyclizine 50 mg by slow intravenous injection 20 min prior to the end of surgery and a patient-controlled analgesia infusion containing morphine 1 mg.ml-1 and cyclizine 2 mg.ml-1. Fifteen of 25 patients (60%) in group 1 and 18 (72%) of 25 in group 2 suffered no nausea or vomiting postoperatively. Two patients (8%) in group 1 and three (12%) in group 2 suffered severe postoperative nausea or vomiting. We conclude that cyclizine is as effective as droperidol in the prevention of postoperative nausea and vomiting when included in a patient-controlled analgesia infusion using morphine.

Infusions of subhypnotic doses of propofol for the prevention of postoperative nausea and vomiting.

We studied the antiemetic effects of a low dose infusion of propofol for 24 h after major gynaecological surgery in a double-blind, randomised, controlled trial. Fifty women of ASA physical status 1 or 2 undergoing major gynaecological surgery received an infusion of 1% propofol or intralipid at 0.1 ml.kg-1.h-1 for 24 h after surgery. Pain was managed using morphine delivered by a patient-controlled analgesia pump. The degree of postoperative nausea and vomiting was assessed by the nurses using a four-point ordinal scale, by the patients using a visual analogue scale and by the amount of rescue antiemetic given by the nurses. There were no differences between the two groups in any of the measures of postoperative nausea and vomiting during the first 48 h after surgery. Postoperative nausea and vomiting in the control group was less on the second day compared with the first postoperative day, but not in the propofol group. There were no side effects from the propofol infusion.

Acupuncture in the prevention of postoperative nausea and vomiting.

The efficacy of intra-operative acupuncture at the PC6 point in the prevention of postoperative nausea or vomiting was studied. A double-blind randomised controlled study of acupuncture versus placebo was performed in 81 patients scheduled for day case gynaecological laparoscopic surgery. Failure of treatment was defined as the occurrence of nausea or vomiting prior to or within 24 h of discharge. The use of acupuncture reduced the incidence of postoperative nausea or vomiting in hospital from 65% to 35% compared with placebo and after discharge from 69% to 31% compared with placebo.

Nausea and vomiting in the postoperative patient-controlled analgesia environment.

Despite common clinical opinion that patient-controlled analgesia should be renamed 'patient-controlled nausea', there is little evidence in support of the notion that postoperative nausea and vomiting are exacerbated by the method. Indeed, data indicate that opioid-sparing techniques are not associated with less postoperative nausea and vomiting. Although some evidence suggests that certain opioids are less emetogenic than others, this too does not stand scrutiny when compared across patients, although research is still required to find whether individual patients are better treated with a particular opioid. Similarly, the emerging practice of combining anti-emetics with patient-controlled analgesia needs wider study before it can be supported.

Comparison of surgical site and patient's history with a simplified risk score for the prediction of postoperative nausea and vomiting.

Although site of surgery and previous occurrence of postoperative nausea and vomiting are often used to decide whether prophylactic anti-emetic drugs are indicated, the value of these predictors is unclear. We compared these two risk factors against a simplified four-factor risk score. We analysed data from 1566 adult inpatients who received balanced anaesthesia without prophylactic anti-emetics. Sensitivity, specificity, predictive value and area under the receiver operating characteristic curve were used to quantify predictive properties. Nausea and vomiting occurred in 600 (38.3%) patients within 24 h. Sensitivity and specificity were, respectively, 47% and 59% for surgical site; 47% and 70% for history of postoperative nausea and vomiting; and 58% and 70% for risk score with three or more factors. The area under the curve for surgical site was 0.53 (95% CI 0.50-0.56); that for patient's history was 0.58 (95% CI 0.56-0.61) while for risk score it was 0.68 (95% CI 0.66-0.71; P < 0.001). Prediction using surgical site or patient's history alone was poor while the simplified risk score provided clinically useful sensitivity and specificity.

Assessing the applicability of scoring systems for predicting postoperative nausea and vomiting.

We have validated two scoring systems for predicting postoperative nausea and vomiting, derived by Apfel et al. and Koivuranta et al. from 1388 adult inpatients undergoing a wide range of surgical procedures. The predictive accuracy of the scoring systems was evaluated in terms of the ability to discriminate between patients with and without postoperative nausea and vomiting (discrimination) and agreement between observed and predicted outcomes (calibration). Discrimination and calibration were less than expected based on previous reports, with both scoring systems providing risk predictions that were too extreme. The area under the ROC curve was 0.63 for Apfel et al.'s scoring system and 0.66 for Koivuranta et al.'s scoring system. Neither of the scoring systems provided a risk threshold for administering anti-emetic prophylaxis that yielded satisfying results in terms of predictive values, sensitivity and specificity. Hence, in their original forms, the scoring systems do not guarantee accurate prediction of the risk of postoperative nausea and vomiting in other patient populations. Koivuranta et al.'s scoring system appears to be more robust across different populations.

Evaluation of capsaicin ointment at the Korean hand acupressure point K-D2 for prevention of postoperative nausea and vomiting.

The K-D2 point is the Korean hand acupressure point in Koryo Hand Therapy for prevention of postoperative nausea and vomiting. We evaluated the efficacy of capsaicin ointment at the K-D2 point in 186 patients undergoing laparoscopic cholecystectomy in a randomised, prospective, double-blind and placebo-controlled study. Patients were randomised to have either placebo ointment or capsaicin ointment applied to the K-D2 point of both hands 1 h before surgery under standardised anaesthesia. The ointment was removed 8 h later. Postoperative nausea and vomiting was evaluated 6 and 24 h following surgery. The incidence of postoperative nausea and vomiting was lower in the capsaicin group, with an absolute risk reduction (ARR) of 21%, a relative risk reduction (RRR) of 50% and a number-needed-to-treat (NNT) of 5 at 0-6 h (p = 0.001), and an ARR of 11%, a RRR of 85% and a NNT of 9 at 6-24 h (p = 0.003). The need for rescue anti-emetic treatment was also lower at 0-6 h (3 (3%) vs 11 (12%); p = 0.04) and at 6-24 h (5 (5%) vs 0; p = 0.02).

Does the efficacy of supplemental oxygen for the prevention of postoperative nausea and vomiting depend on the measured outcome, observational period or site of surgery?

High intra-operative oxygen concentration reportedly reduces postoperative nausea and vomiting (PONV), but recent data are conflicting. Therefore, we tested whether the effectiveness of supplemental oxygen depends on the endpoint (nausea vs. vomiting), observation interval (early vs. late) or surgical field (abdominal vs. non-abdominal). We randomly assigned 560 adult patients undergoing various elective procedures with a PONV risk of at least 40% to intra-operative 80% (supplemental) or 30% oxygen (control). Potential confounding factors were similar between groups. Incidences of nausea were similar in the groups during early (12% (supplemental) vs. 10% (control), p = 0.43) and late intervals, 26%vs. 20%, p = 0.09, as were the incidences of vomiting (early: 2%vs. 3%, p = 0.40; late: 8%vs. 9%, p = 0.75). Supplemental oxygen was no more effective at reducing PONV in abdominal (40%vs. 31%, p = 0.37) than in non-abdominal surgery (25%vs. 21%, p = 0.368). Thus, supplemental oxygen was unable to reduce PONV independent of the endpoint, observational period or site of surgery.

A comparison of cyclizine and granisetron alone and in combination for the prevention of postoperative nausea and vomiting.

We conducted a randomised double-blinded study of 960 women undergoing day-case surgery to determine whether combination anti-emetic therapy of granisetron and cyclizine was more effective at decreasing the incidence of postoperative nausea and vomiting than these agents used alone. The women were randomly allocated to three groups to receive intravenous granisetron 1 mg, cyclizine 50 mg or both before induction of general anaesthesia. The incidence of postoperative nausea and vomiting was 77/322 (24%) in the granisetron group, 73/316 (23%) in the cyclizine group and 53/322 (17%) in those women given both drugs (p = 0.04). There was no difference in the requirement for rescue anti-emetic drugs. There were no differences in the anaesthetic techniques used in the three groups. We conclude that the risk of postoperative nausea and vomiting is less with cyclizine and granisetron given together than with either given alone.

Responses of plasma oxytocin and arginine vasopressin to nausea induced by apomorphine and ipecacuanha.

Apomorphine, a centrally-acting emetic, was administered subcutaneously (50 micrograms/kg) to nine normal subjects (four male, five female; aged 22-36 years) and four patients with idiopathic diabetes insipidus (DI) (one male, three female; aged 24-49 years). In the normal subjects this stimulus caused nausea (and vomiting in seven of nine) with a latency of 9.5 +/- 0.9 min which was followed by a large increase in plasma arginine vasopressin (AVP) concentration (from 0.9 +/- 0.2 pmol/l to 249 +/- 104 pmol/l at 15 min after the onset of symptoms; mean +/- SEM, P less than 0.01). There was a small but significant increase in plasma oxytocin (OXT) concentration (from 1.6 +/- 0.4 pmol/l to 6.2 +/- 3.4 pmol/l; P less than 0.05). Mean arterial pressure (MAP) fell slightly (from 87 +/- 1.9 mm Hg to 71 +/- 4.4 mm Hg; P less than 0.05) 15 min after the onset of nausea; there was no change in blood haematocrit or plasma osmolality and sodium concentration. In the DI patients apomorphine produced nausea (with vomiting in three of four) with a latency of 10.0 +/- 1.4 min but failed to cause an increase in either plasma AVP or OXT. In the DI patients the fall in MAP did not reach statistical significance (83 +/- 4 mm Hg to 71 +/- 11 mm Hg); there was also no change in haematocrit, osmolality or sodium concentration. Ipecacuanha, an emetic with both peripheral and central actions, was administered orally to seven normal subjects (three male, four female; aged 22-36 years) six of whom also underwent apomorphine tests.(ABSTRACT TRUNCATED AT 250 WORDS)

Chemotherapy-related nausea and vomiting - past reflections, present practice and future management.

Although much progress has occurred in the last decade regarding the management of chemotherapy-induced nausea and vomiting, these remain among the most intolerable side-effects of treatment and patients continue to report the negative impact such symptoms have on their ability to enjoy life. Inadequate control of nausea and vomiting reduces patients' quality of life and functional status and jeopardizes the delivery of optimal treatment, so making its management a priority for oncology health care workers. This article will reflect on past and present evidence regarding the management of chemotherapy-induced nausea and vomiting while highlighting some of the most recent scientific advances before drawing conclusions about the future management of this troublesome symptom for patients receiving chemotherapy.

Theories of self-care: their relevance to chemotherapy-induced nausea and vomiting.

Nausea and vomiting are reputed to be two of the most disruptive side-effects associated with chemotherapy. Pharmacological and behavioural interventions are well described in the literature, but sparse attention appears to have been focused upon the role of self-care. This paper outlines the problem of chemotherapy-induced nausea and vomiting. The concept of self-care is described, including possible motivations to perform self-care, and potential relationships between symptom perception and self-care are noted. It concludes with suggestions for theoretical work and future research studies concerning self-care behaviour for nausea and vomiting induced by chemotherapy.

Evaluation of the Rhodes Index of Nausea and Vomiting for ambulatory surgery patients.

BACKGROUND: The Index of Nausea and Vomiting (INV), developed by Rhodes and others in 1984, measures three dimensions of upper gastrointestinal distress: nausea, vomiting and retching (NVR). While the revised version has been tested with a variety of high-risk populations, there are no data suggesting that it can be used to assess upper gastrointestinal distress among the growing numbers of ambulatory or day surgery patients. AIM: The aim of this study was to evaluate a modified version of the INV for use with ambulatory surgery patients. METHODS: A secondary analysis was conducted using data obtained from a descriptive study designed to identify risk factors for postdischarge nausea and vomiting (PDNV) among adult ambulatory surgery patients. Patients who reported PDNV (n = 190) participated via phone interview 24 hours after discharge by completing a modified Rhodes INV. FINDINGS: Reliability analysis (alpha = 0.897) indicated that the modified Rhodes INV measured upper gastrointestinal distress as a single concept in the postdischarge ambulatory surgical sample. One item of the 8-item scale was dropped. Principal component analysis extracted one factor that accounted for 67% of the variance with all items loading. CONCLUSIONS: Upper gastrointestinal distress following ambulatory surgery discharge comprises a different symptom mix than during other high-risk events such as pregnancy or chemotherapy. Further research on the differences in assessing NVR among different populations is indicated.

Postanaesthetic nausea in children.

The incidence of emetic episodes during the first 24 h after anaesthesia was studied prospectively in 485 children aged 0-16 years in relation to age, premedication, type of induction, type and duration of anaesthesia, type of surgery and use of postoperative analgesics. The incidence of emetic episodes was 25% in the whole material. The majority of the emetic episodes were recorded after the immediate recovery period. In children under 2 years of age, vomiting was only recorded in 5%. Nausea and vomiting was most common after squint surgery (75%) and least common after endoscopies (17%). Neither premedication with diazepam nor the method of induction (thiopentone, i.v., thiopentone rectally, inhalation with halothane) influenced the incidence of nausea. For the same type of surgery, maintenance of anaesthesia with halothane resulted in a lower incidence of nausea than anaesthesia with fentanyl-pancuronium.
