Introduction: Postoperative nausea and vomiting (PONV) is prevalent among surgical patients, causing hospitalizations, extended stays, and patient dissatisfaction. Children are twice as likely to experience PONV than adult patients. Complementary therapy holds promise for PONV treatment but meets clinical use barriers. We explored perioperative nurses' perceived barriers to the use of complementary aromatherapy., Method: Presurvey and postsurveys assessed nurses' (n = 27) knowledge and barriers to aromatherapy use before and after an educational in-service., Results: Primary PONV treatment involved antiemetics. Barriers to aromatherapy included product availability, caregiver refusal, and patient-specific factors. Post-in-service, the nurses felt more familiar with aromatherapy and inclined to use it., Discussion: Increased education and guidelines on aromatherapy promote its incorporation into clinical practice. Institutional policies addressing the selection, administration, documentation, and monitoring of aromatherapy should be established to ensure the consistency and standardization of its use., Competing Interests: CONFLICTS OF INTEREST None to report., (Copyright © 2023 National Association of Pediatric Nurse Practitioners.

Purpose: To create and implement a standard care bundle to reduce postoperative nausea and vomiting (PONV) in the bariatric surgery patient., Design: Evidence-based quality improvement project., Methods: A pre- and postintervention chart review identified high-risk indicators for PONV in patients with longer lengths of stay (LOS), which led to the development of targeted care bundle components., Findings: A clinically significant difference was observed in predicted PONV for Apfel scores 3 and 4 in patients receiving the full bundle compared with those receiving a partial bundle. Decreased LOS after implementation of the antiemetic care bundle was found. Health care provider compliance with bundle administration was low (57%)., Conclusions: Clinically significant PONV scores were low after implementation of the antiemetic bundle for high-risk patients. The nurse-led creation and implementation of an antiemetic care bundle may have contributed to decreased LOS, reduced PONV, and reduced provider variability in care management., (Published by Elsevier Inc.)

Postoperative nausea and vomiting (PONV) is an unpleasant complication following anesthesia and surgical procedures experienced by both adults and children. Compared with adults, children are 2 times more likely to experience PONV. Many studies have identified and independently validated risk factors associated with the development of PONV in the pediatric population. Chief among these are patient age greater than 3 years, surgical duration greater than 30 minutes, surgical type, and a history of PONV. The purpose of this evidence-based practice change was to investigate if preoperative documentation of a patient's PONV history will lower PONV rates postoperatively. A PONV history assessment tab was created to aid in the documentation of the patient's PONV history, and a retrospective chart review was conducted 2 months before and 2 months after the practice change. A total of 2,279 preintervention cases were compared with 2,006 postintervention cases. Rates of PONV dropped 22%, from 153 preintervention cases to 120 postintervention cases, demonstrating a significant (P = .0043) decrease in PONV rates following a patient's reported history of PONV. Documentation of a patient's PONV history preoperatively led to a decrease in postoperative rates of PONV., Competing Interests: The author has declared no financial relationships with any commercial entity related to the content of this article.

Anesthesia providers have a myriad of medication options when developing and implementing a plan for the management of postoperative nausea and vomiting (PONV). However, anesthetists must be aware of the potential side effects, complications, and interactions of those medications, especially when managing high-risk populations. Although guidelines exist for the management of PONV in the general population, an evidence-based antiemetic decision support tool has not been developed for patients at risk of prolonged QT interval or for patients who are routinely receiving neurotransmitter-modulating medications. Safe practice recommendations exist but are scattered throughout the literature. The goal of this project was to develop a tool for anesthetists that concentrates the evidence and provides practice guidelines in these 2 selected populations. The methods for developing this tool were to perform a thorough literature search to gather evidence-based guidelines, organize findings in a convenient easy-to-read format, and validate guidelines by consultation with an expert panel. The product is a quickly accessible clinical tool listing guidelines for 8 commonly used antiemetic agents to assist anesthetists in PONV management., Competing Interests: The authors have declared no financial relationships with any commercial entity related to the content of this article.

The worldwide obesity epidemic has led to an increase in the number of bariatric procedures for treatment. Currently, the most commonly performed bariatric surgical operation in the United States is the laparoscopic sleeve gastrectomy (LSG). The risk of postoperative nausea and vomiting (PONV) is exceptionally high following the LSG: as much as 65%. Anesthesia providers should be mindful of this elevated risk and stay up to date on evidence-based techniques that help to mitigate the incidence of PONV related to this specific procedure. The purposes of this clinical review are to increase provider awareness of the PONV risk following LSG and to examine methods for improving PONV outcomes for this population., Competing Interests: The authors have declared no financial relationships with any commercial entity related to the content of this article.

Postoperative nausea and vomiting (PONV) remains one of the most common adverse effects of anesthesia, affecting up to 80% of high-risk patients within 24 hours after surgery. Patient-related factors, surgical procedure, and perioperative medications such as opioids determine a patient's risk for PONV. To prevent and manage PONV, ondansetron, a 5-hydroxytryptamine type 3 (5-HT 3 ) receptor antagonist, is frequently administered. Ondansetron is metabolized predominantly by hepatic cytochrome P450 (CYP2D6) enzymes, encoded by the CYP2D6 gene, whereas most of the effects of opioids are exerted at the opioid mu-1 receptor, encoded by the OPRM1 gene. Genetic polymorphisms of the CYP2D6 and OPRM1 genes may have a role in interindividual variation in the occurrence of PONV. Specifically, the occurrence of the G-allele produced by the OPRM1 A118G appears to be protective against PONV, whereas CYP2D6 ultrarapid metabolism increases the risk for PONV. The Clinical Pharmacogenetics Implementation Consortium guidelines provide CYP2D6-guided therapeutic recommendations for ondansetron. However, further studies are needed to investigate the role of genetic polymorphism in the occurrence of PONV and response to antiemetics., (Copyright © 2019 American Society of PeriAnesthesia Nurses.

Aim and Objectives: To validate the Numeric Rating Scale (NRS) for postoperative nausea assessments, and determine whether a central tendency, median, based on patients' self-rated nausea is a clinically applicable daily measure to describe patients' nausea after major surgery., Background: Postoperative nausea causes major discomfort, risks for complications and prolonged hospital stays. The NRS is recommended for the assessment of pain but is little explored for assessing nausea., Design: A repeated measure design was carried out on patients who had undergone major surgery in three Swedish hospitals., Methods: Nonparametric statistical methods were used to analyse (a) associations between the NRS and a verbal scale (no, mild, moderate and severe) and (b) to analyse associations between Measure 1 (nausea scores postoperative Day 1) and Measure 2 (retrospective nausea scores at rest and during activity, postoperative Day 2). Reporting of this research adheres to the Strobe Guidelines., Results: The mean age of the 479 patients (44% women) in the sample was 65 years (range, 22-93 years). Self-assessed nausea scores from the NRS and the verbal scale correlated well (r S pearman  = 0.79). Correlation between nausea at rest and nausea during activity was r S pearman  = 0.81. The calculated median scores (Measure 1) showed only moderate correlations with retrospective nausea scores (Measure 2); 4-9 ratings, r S pearman  = 0.41; 6-9 ratings, r S pearman  = 0.54., Conclusions: Numeric Rating Scale scores showed strong associations with a verbal scale; therefore, the NRS seems to be a valid tool to measure nausea intensity. The quality of daily summarised median nausea scores needs to be further explored before clinical use., Relevance to Clinical Practice: The use of the NRS in assessments of nausea in postoperative care will facilitate communication between patients and health care professionals regarding nausea intensity. When documenting nausea, it seems unnecessary to distinguish nausea at rest from nausea during activity., (© 2018 John Wiley & Sons Ltd.)

Postoperative nausea and vomiting (PONV) is a major concern for short-stay surgical patients because it can delay discharge and cause preventable postoperative complications, which in turn can increase hospital costs. Evidence suggests that aromatherapy effectively reduces PONV, either as a monotherapy or in conjunction with pharmacologic antiemetics. This quality improvement project investigated the effectiveness of aromatherapy in reducing PONV in a short-stay surgical population. The outcome of this project supported the hypothesis that the administration of blended aromatherapy would result in a significant decrease in patients' self-reported ratings of nausea. This finding suggests that aromatherapy is an appropriate adjunct therapy for decreasing patient nausea and vomiting in this short-stay surgical unit and may help prevent discharge delays in this population., (© AORN, Inc, 2018.)

Postoperative nausea and vomiting (PONV) continue to be among the most undesirable and distressing complications following general anesthesia, affecting 20% to 30% of all surgical patients and up to 70% of patients with multiple known risk factors. The purpose of this study was to reexamine the effectiveness of metoclopramide in the prevention of PONV when stratified by PONV risk scores. Secondary data from 2,116 adult ambulatory surgical patients were analyzed. Participants were, on average (SD), 49.7 (15.4) years of age, with a mean body mass index of 28.3 (6.9) kg/m², and were primarily female (65%). Risk scores for PONV ranged from 0 to 4, with a mean of 2.6 (1.0). Metoclopramide, 10 mg intravenously (IV) alone; metoclopramide, 10 mg IV, combined with ondansetron, 4 mg IV; and metoclopramide, 10 mg IV, combined with dexamethasone, 8 mg IV, and ondansetron, 4 mg IV, had a beneficial effect for adult ambulatory surgical patients with PONV risk scores of 1 to 4. Although this cohort study had limitations, future studies should investigate metoclopramide based on risk score recommendations, and guidelines should be reevaluated., Competing Interests: The authors have declared no financial relationships with any commercial entity related to the content of this article.

Background and Purpose: At least one-third of ambulatory surgery patients will experience nausea or vomiting during the recovery period. The purpose of this study was to examine the psychometric properties of the Ambulatory Surgery Index of Nausea, Vomiting, and Retching (AS-INVR)., Methods: Secondary analysis of longitudinal data from a study of 203 adult ambulatory surgery patients was conducted., Results: Based on the results of factor analysis, the retching item was eliminated and the 6-item, 2-dimensional AS-INV was formed. Cronbach's alphas for the AS-INV ranged from .83 to .87 across the 5 days postsurgery. Higher AS-INV scores were associated with self-reported presence of nausea and lower quality of life., Conclusions: The shortened AS-INV provides a reliable and valid measure of the amount and distress because of nausea and vomiting in adult patients after ambulatory surgery and should be considered for use in future studies.

Aim The aim of this literature review was to explore the reasons why some patients are not suitable for discharge following day surgery. Method A pragmatic, mixed-methods approach was used to undertake a critical evaluation of the literature and current practice to determine what is already known about discharge following day surgery. Thematic analysis was used to identify the main themes and issues, enabling recommendations to be made to reduce the incidence of patients unable to be discharged following day surgery. Findings The main themes or reasons for delayed discharge following day surgery identified from the literature review were: post-operative nausea and vomiting, post-operative pain, going late to theatre and social factors. These themes were supported by the findings of an unpublished audit carried out in one day surgery unit in an NHS healthcare organisation in the south of England between June and August 2014, which indicated that 54 out of 1,180 day surgery patients required an overnight stay during this 12-week period. The audit also showed that a patient going late to theatre had the greatest effect on discharge outcomes. Conclusion Recommendations for practice include: the introduction of post-operative nausea and vomiting risk scoring and prophylactic protocols; reorganisation of theatre lists to ensure patients have enough time to recover; and provision of information during the pre-assessment process about the requirement for a responsible adult escort to take patients home and stay with them for the first 24 hours. These changes may help NHS organisations to improve discharge outcomes for day surgery patients and reduce unplanned costs.

Postoperative nausea and vomiting (PONV) is a daily concern for patients and perianesthesia nurses. PONV is experienced by approximately one third of all surgical patients. Identification of patients at risk for PONV through preoperative risk assessment is an effective means in reducing the incidence of PONV. Perianesthesia nurses are positioned to implement such risk assessments by using simplified risk scores to identify moderate to high-risk patients. Risk assessment allows for facilitation of targeted prophylaxis which positively impacts the patients' surgical outcome and experience. Targeted prophylaxis is efficacious in reducing the institutional incidence of PONV which decreases resource utilization and cost. The perianesthesia nurse is the crucial component in minimizing the PONV in the post-surgical patient. This evaluation of the evidence reveals that preoperative PONV risk screening leads to decreased incidence of PONV for the surgical patient, improves patient satisfaction and reduces postoperative complications., (Copyright © 2016 American Society of PeriAnesthesia Nurses.

This paper describes a quality improvement project designed to decrease postoperative pain, decrease post-operative nausea and vomiting (PONV), decrease time in the recovery room, and increase patient satisfaction in adult ambulatory septoplasty patients using a multimodal, preemptive analgesic regimen. The project was conducted in a community hospital setting with nine operating rooms, and a twenty one bed recovery room. Project participants included certified registered nurse anesthetists, anesthesiologists, operating room nurses, recovery room nurses, and otolaryngology surgeons. Following a period of departmental education, adult patients scheduled for outpatient septoplasty surgery received a preoperative regimen of medications that included gabapentin, celecoxib, and acetaminophen. Using a pre-post test design, (intervention group n = 17, non-intervention group n = 17) data was collected from patient and analyzed using SPSS version 18.0. The change in practice resulted in a significant decrease in pain scores in the recovery room and on discharge from the recovery room. In addition, patients who received the preemptive regimen also required significantly fewer opioid medications and were ready to be discharged from the recovery room in less time.

Tonsillectomy and adenotomy are the most common pediatric surgical procedures, with approximately five millions performed each year worldwide (O'Mathúna, Wiffen & Conlon, 2010). However, this procedure is accompanied by significant postoperative morbidity, which may include postoperative pain, postoperative nausea and vomiting (PONV), poor oral intake with consequent dehydration and postoperative bleeding (Hanasono et al., 2004). If pain is not treated effectively, it can cause avoidance behaviors related to further healthcare. Inadequate pain management has been found to increase morbidity and mortality rates in postoperative patients of all ages (O'Mathúna, Wiffen & Conlon, 2010). In addition, there is an increase in the incidence of PONV: 40% in children with pain compared to 16% in children without pain. PONV also disturbs significantly the wellbeing and patient satisfaction, it can lead to a substantial prolongation of time in the recovery room with increased costs of personal care. In pediatric patients PONV is the most common cause of the approximately 1% to 2% of unplanned hospitalizations following outpatient surgery (Rüsch et al., 2010). The incidence of bleeding after tonsillectomy is approximately 0.5-10%, with deaths occurring in 1 in 20,000 patients (Kim et al., 2011). In recent years, several scientists have explored the effect ofcorticosteroids in the reduction of morbidity after tonsillectomy. In this publication, the question is addressed to what extent perioperatively administered corticosteroids can reduce pain, PONV and postoperative bleeding in the context of tonsillectomy in children and adolescents. For this purpose, a narrative literature analysis of the electronic databases and journals was conducted. There is evidence that corticosteroids can reduce postoperative morbidity. However, no evident and clear recommendation can be drawn from the advices of the various studies.

Purpose/objectives: To examine the association of the serotonin transport gene and postdischarge nausea and vomiting (PDNV) in women following breast cancer surgery., Design: A cross-sectional study., Setting: A comprehensive cancer center in Pittsburgh, PA., Sample: 80 post-menopausal women treated surgically for early-stage breast cancer., Methods: Data were collected using standardized instruments after surgery but before the initiation of chemotherapy. Blood or saliva were used for DNA extraction and analyzed following standardized protocols. Data were analyzed using descriptive statistics and logistic regression., Main Research Variables: Serotonin transport gene (SLC6A4), nausea, vomiting, pain, and anxiety., Findings: Women who inherited the LA/LA genotypes were at greater risk for nausea and vomiting when compared to women who carried any other combination of genotypes. Twenty-one percent of women reported nausea and vomiting an average of one month following surgery and prior to initiation of adjuvant therapy. Those women who experienced PDNV reported significantly higher anxiety and pain scores., Conclusions: Findings of this study suggest that variability in the genotypes of the serotonin transport gene may help to explain the variability in PDNV in women following breast cancer surgery and why 20%-30% of patients do not respond to antiemetic medications., Implications for Nursing: Nurses need to be aware that women who do not experience postoperative nausea and vomiting following surgery for breast cancer continue to be at risk for PDNV long after they have been discharged from the hospital, and this frequently is accompanied by pain and anxiety.

Postoperative nausea and vomiting (PONV) remains a common postoperative complication that causes patient discomfort and increases health care costs. Clinicians use the American Society of PeriAnesthesia Nurses (ASPAN) guideline to help prevent and treat PONV. However, the lack of standardized terminology in the electronic health record (EHR) and the lack of clinical decision support tools make it difficult for clinicians to document guideline implementation and to determine the effects of nursing care on PONV. To address this, we created a concept map of the Perioperative Nursing Data Set (PNDS) that illustrates the relationship between elements of this standardized nursing terminology and the ASPAN guideline, using the Systematized Nomenclature of Medicine-Clinical Terms multidisciplinary terminology to fill any gaps. This mapping results in a standardized dataset specific to PONV for use in an EHR, which links nursing care to nursing diagnoses, interventions, and outcomes. The mapping and documentation in the EHR also allows standardized data collection for research, evaluation, and benchmarking, which makes perioperative nursing care of patients who are at risk for or experiencing PONV measureable and visible. Distributing this information to perioperative and perianesthesia nursing personnel, in addition to implementing risk assessment tools for PONV and clinical support alerts in electronic documentation systems, will help support implementation of the PONV clinical practice guideline in the EHR., (Copyright © 2013 AORN, Inc.

Post-operative nausea and vomiting (PONV) is a common complication for many surgical patients, causing anxiety and distress. Evidence suggests that nursing practice in this area is inconsistent and that nurses' knowledge needs to improve, to promote better patient outcomes. This article provides a review of the incidence of PONV, associated complications and risk factors. Examples of risk assessment tools that could be used to identify patients at risk of developing PONV are described to ensure timely and appropriate treatment.

For surgical patients, postoperative nausea and vomiting (PONV) is one of the most undesired complications of anesthesia and surgery.

Background: One-third of surgical outpatients experience postoperative nausea and vomiting (PONV) during their hospital stay or post-discharge nausea and vomiting (PDNV) after hospitalization. We determined the incremental costs of PONV/PDNV in ambulatory patients with this time-and-motion study., Methods: In 100 ambulatory surgery patients, we evaluated the incidence of PONV, time staff spent with patients, use of PONV-related supplies, recovery duration, PONV rescue treatments, and quality-of-life through to the third postoperative morning. Patients with and without PONV/PDNV were compared in relation to PONV-related cost after adjusting for age, American Society of Anesthesiologists status, body mass index, and duration and complexity of surgery., Results: Thirty-seven percent of the patients experienced PONV during hospitalization; this increased to 42% by the first postoperative morning and increased further to 49% by the third postoperative morning. Patients with PONV spent one hour longer in the postanesthesia care unit than patients without PONV (median [interquartile range] 234 [188-287] min vs 171 [144-212] min, respectively; P = 0.001). The amount of nursing time required for patients with PONV was significantly greater than that required for patients without PONV (82 [63-106] min vs 68 [57-79] min, respectively; P = 0.02). The total cost of postoperative recovery was significantly greater for patients with PONV/PDNV than for those without (US$730 vs $640, respectively; P = 0.006). Postoperative nausea and vomiting/PDNV was associated with an adjusted incremental total cost of $75 (95% confidence interval $67 to $86). Postoperative nausea and vomiting was also associated with worsened postoperative quality of life (49% of patients with PONV/PDNV rated quality high in four domains vs 94% of patients without PONV/PDNV; P < 0.001)., Conclusion: Postoperative nausea and vomiting/PDNV were common; they impaired quality of life and imposed an incremental cost of $75 per patient. This incremental cost is comparable with the cost patients are willing to pay to avoid PONV.

Ephedrine, a well-known sympathomimetic agent, is used in the perioperative setting to treat acute hypotension, especially hypotension related to anesthetic events. Ephedrine's unlabeled use as an antiemetic agent is less well known despite its efficacy and safety profile for short-term and/or prophylactic treatment. The following case report describes the benefits of using ephedrine to mitigate postoperative nausea and vomiting and associated dizziness while waiting for longer lasting therapy to take effect and/or use as a secondary agent., (Copyright © 2011 American Society of PeriAnesthesia Nurses.

Nausea and vomiting is a common post-operative complication that exacerbates patient discomfort and puts tension on suture lines, which may cause hematomas beneath surgical flaps and place patient at risk of aspiration pneumonia. Nausea and vomiting decreases patient comfort and satisfaction and increases hospital stay length and costs. Postoperative nausea and vomiting are common occurrences. Nurses typically give medicine in accordance with doctors' orders without understanding patient symptoms. Such results in less than optimal holistic care management. This situation encouraged the author to collect references on current international trends related to postoperative nausea and vomiting treatment in the clinical setting. The author further worked to recommend a care management protocol based on findings. This paper describes risk factors of postoperative nausea and vomiting and the related drugs, prevention procedures, and treatment recommendations. Finally, the author developed a simple care flow chart suited for use in internal clinical situations that may provide a valuable reference for medical professionals.

Aim: The aim of the study was to illuminate the experience of nurses in relieving postoperative nausea and vomiting., Background: Postoperative nausea and vomiting has been shown to be one of the most common and distressing side effects of surgery. In spite of this, there has been little research on the role of nurses in caring for patients with postoperative nausea and vomiting., Design: Qualitative approach using narratives., Methods: Ten female nurses from two general surgical departments were interviewed. The transcribed interviews were analysed using the hermeneutic narrative method inspired by Polkinghorne., Results: The nurses report that they have what may be described as a set of different tools at their disposal. These tools can be entitled 'listen and understand', 'information', 'the clinical eye' and 'availability', all of which can be used in solving several needs. However, some nurses have better skills or more opportunities to use the available tools than do others. By using these tools, the nurses can increase their possibilities for enhancing the patients' efforts to gain control over their own situation and thereby increase the quality of their care., Conclusion: Nurses use different types of tools to relieve postoperative nausea and vomiting and it is possible to create a positive nursing care situation if patients are given the opportunity to be in control and handle their own situation., Relevance to Clinical Practice: When it comes to relieving postoperative nausea and vomiting, the findings of this study are important as the study highlights the practical actions taken by nurses and their experiences. When nurses have the possibility to use their nursing tools in an optimal way, together with their experience and knowledge and then follow their nursing actions by being able to reflect on them, they can further develop their approach to nursing and thereby increase their competence as nurses., (© 2010 The Authors.

In this, the second of a 2-part article, the author discusses the postoperative care of patients who undergo enucleation of the eye. Part one explored aspects of preoperative care of enucleated patients. In the immediate period following surgery, patients require support and advice regarding pain, nausea and simple care of the eye socket. Apart from the intrinsic postoperative demands of the surgery, there are also the difficulties and challenges associated with providing psychological support and helping patients cope with the loss of an eye. Ultimately, the patient can overcome any initial problems and eventually be able to wear a custom-made prosthesis, which will hopefully allow the patient to move on with their lives. As in the first part, the author will use both referenced material and anecdotal references (upon personal reflection) to analyze the ongoing postoperative care and support of these patients.

Postoperative nausea and vomiting continues to be a distressing problem despite the availability of new information. Identifying gaps in nursing knowledge and then creating a culture of learning is one way to address these potentially harmful symptoms.

Children requiring posterior fossa brain tumour surgery form a unique and significant neuro-oncology population. Postoperative vomiting (POV) is a problem for these children. Also, severe vomiting that is refractory to treatment has been seen clinically in these children, but it is not well described in the literature. A subgroup of children requiring surgery for posterior fossa brain tumours (n=153) from a larger six-year retrospective chart audit (n=249) at two Canadian children's hospitals were reviewed for the presence of no, mild, moderate, and severe POV. Inter-rater reliability was established at 94% following a blinded process of comparing POV severity rankings between two data collector/researchers. Discrepancies were resolved through discussion in order to establish a consensus severity score. Findings from multivariable logistic regression analyses indicated that when age and intraoperative use of ondansetron were controlled for, the location of a tumour in a midline location had no overall effect (adjusted OR=1.37, 95% confidence interval: 0.64-2.96, p=0.43), but greater odds of severe vomiting (adjusted OR=7.08, 95% confidence interval: 2.56-19.64, p<0.001). These results support theories of modulation of vomiting by the medullary midline and clinical observations that children with midline posterior fossa tumours are at greater risk for severe refractory vomiting. The development of clinical practice guidelines and further research to study the effectiveness of novel, multimodal antiemetic therapies are required for this patient population.

The purpose of this meta-analysis was to estimate the efficacy of prophylactic administration of 5-HT3 receptor antagonists for postoperative vomiting (POV) in pediatric craniotomy patients at 24 hours. By updating a previously published systematic literature search, we found a recently published pediatric study to combine with the one already identified. The two published randomized placebo-controlled trials were combined for a total of 135 participants aged 2 to 20 (79 treatment and 56 controls). The only study drug was ondansetron. The combined relative risk (RR) of vomiting was not statistically significant in the treatment group compared to the control group (RR = 0.77; 95% CI: 0.50-1.19). There was also no evidence of efficacy for ondansetron in reducing the use of rescue antiemetics in the treatment group compared to the control group (RR = .71; 95% CI: 0.34-1.49). While combining these randomized placebo-controlled trials did not show efficacy for ondansetron in preventing POV in craniotomy patients aged 2 to 20, a clinically significant effect cannot be excluded, as even the combined sample size remained small. Thus, there is no current evidence for or against this class of drugs for preventing POV in children after craniotomy, and clinical decision-making must be based on studies in other populations and clinical experience. Ongoing assessment of nausea and vomiting and ongoing evaluation of the effectiveness of treatments in individual children and young adults remains an essential part of perianesthesia and postoperative neuroscience nursing.

Postoperative nausea and vomiting (PONV) remains a ubiquitous concern for surgical outpatients with published rates ranging from 14% to 80%. An evidence-based approach was used to reduce PONV in a high-risk adult outpatient oncology population. The Observe, Orient, Decide, and Act (OODA) Loop, a rapid cycle management strategy, was adapted for use in an outpatient surgery center with six ORs. A PONV prophylaxis protocol was developed and adapted until a stable PONV rate was achieved. A combination of dexamethasone, promethazine, and ondansetron was used in patients with one to three PONV risk factors. Patients with four major risk factors received an additional intervention. The PONV rate for the final protocol stabilized below 4% by 46 weeks and remained stable through 79 weeks. The OODA paradigm provides an effective technique for interfacing health care research with clinical practice. In this case, an effective PONV prophylaxis plan was developed from within a collaborative nursing and medical setting.

Aims of the Review: To consider the efficacy of dexamethasone in preventing postoperative nausea and vomiting following general anaesthesia and a range of surgical procedures, compared with a placebo of sodium chloride (normal saline). To inform nurses' pharmacological knowledge of the effects of this medication during peri-operative care., Background: Dexamethasone was serendipitously discovered to have an effect on reducing postoperative nausea and vomiting for patients receiving various chemotherapeutic regimes. Experience suggests many nurses remain unaware of the anti-emetic effect of this medication., Methods: Multiple databases were searched and selected articles were restricted to experiments published within the past 10 years. Participants of each study had received dexamethasone or sodium chloride (not administered in combination with any other anti-emetics) preoperatively, undergone general anaesthesia and received a common surgical procedure. Thirteen research articles met these criteria and were reviewed., Results: The surgical procedures represented have shown high incidences of postoperative nausea and vomiting associated with them. Importantly, 12 of the 13 trials reported significant reductions suggesting dexamethasone has a significant preventative effect in reducing the incidence of postoperative nausea and vomiting when given during induction. However, as a preventative of postoperative nausea alone, dexamethasone does not appear to have a significant effect., Conclusions: The findings clearly support the notion that dexamethasone does have anti-emetic properties. Research examining dexamethasone in combination with other drugs as a cocktail of anti-emetics is welcomed. Future research into the usefulness of dexamethasone given beyond the induction period as an anti-emetic to inform postoperative protocols of care is needed., Relevance to Clinical Practice: Nurses in the peri-operative arena can administer this medication, when ordered, with the knowledge based on research evidence as to why it has been included in preoperative protocols. However, dexamethasone has been noted in postanaesthesia recovery care units as a clinical pathway option for the management of postoperative nausea and vomiting and no retrieved articles discuss this option.

Nurses working in perianesthesia care areas use discharge scoring criteria to complete patient assessments and ensure patient readiness for discharge or transfer to the next phase of recovery. However, all discharge criteria have both advantages and disadvantages. Comparative studies on the reliability of the different discharge criteria in use are extremely limited. As the acuity of our aging population increases, as well as the number of annual surgeries performed on an outpatient basis, it is most timely to ensure that we are following evidence-based discharge criteria.

Postoperative nausea and vomiting (PONV) is a frequent complication of surgery. Guidelines recommend using a 5-HT3 receptor antagonist (eg, ondansetron, dolasetron, granisetron) combined with a second agent (eg, dexamethasone) for patients at moderate to high risk for PONV. Although all 5-HT3 antagonists are effective, ondansetron and granisetron have been found to be effective at substantially lower doses than those approved by the US Food and Drug Administration. Metabolism of granisetron differs from metabolism of other 5-HT, antagonists, so it is less likely to adversely interact with other medications. This article explains the clinical pharmacology of 5-HT3 antagonists and provides recommendations for nursing management of PONV.

The potential for postoperative nausea and vomiting is present in any patient who undergoes surgery and both are unpleasant and potentially dangerous consequences of surgery. Three types of complementary and alternative therapies that may help patients with postoperative nausea and vomiting include acupressure, acupuncture, and aromatherapy.

Advanced practice nurses are involved in many aspects of program development as part of their roles. This can involve such things as developing programs for staff and family education, organizing system-wide quality assurance programs, or implementing new care programs. One unique aspect of the advanced practice nurse's role is the ability to serve as a change agent and implement new models of care. Although all advanced practice nurses can be involved in program development, the role of the Clinical Nurse Specialist lends itself to devoting dedicated services for implementing programmatic change in the clinical setting. This article describes the role of the Clinical Nurse Specialist in implementing an evidence-based, fast-track postanesthesia care unit.

In my practice as a recovery room nurse, I had observed anesthesiologists and nurse anesthetists wave an opened alcohol preparation pad under a patient's nose when he or she complained of nausea. When asked, "Why?'' the response often was, "Because it works.'' The following article describes the use of inhalation of isopropyl alcohol as a treatment for postoperative nausea and vomiting. Because alcohol swabs are so readily available, and certainly less expensive than some of the newer antiemetics on the market, this simple nursing intervention was worth investigating.

Study Objective: To track the incidence of in-hospital postoperative nausea and vomiting (PONV) requiring postoperative parenteral nursing interventions after outpatient reconstruction of the anterior cruciate ligament (ACL) with one of two types of regional anesthesia to determine the extent to which various anesthetic techniques, preemptive antiemetics, and other factors were associated with the lowest probability of PONV., Design: Retrospective chart (database) review of all ACL procedures at the University of Pittsburgh Medical Center from August 1997 through June 1999., Setting: University medical center., Measurements: We reviewed our institutional database of 347 consecutive patients undergoing ACL reconstruction with either spinal with femoral nerve block (SPI-FNB) or lumbar plexus and sciatic nerve block (LUM-SCI). Recorded variables and outcomes included gender, history of PONV, intravenous (i.v.) fentanyl before and during surgery, preemptive antiemetics given, and parenteral nursing interventions for PONV performed. Chi-square tests and logistic regression were used to determine factors associated with PONV., Main Results: For SPI-FNB, PONV incidence was 13% (26/208), but it was higher for LUM-SCI [25%, 34/139, p = 0.002; odds ratio (OR) = 2.2]. Regression modeling demonstrated that women (OR = 2.8, p = 0.003) and LUM-SCI patients (OR = 3.0, p = 0.005) were at greater risk for PONV. The combination of dexamethasone (4 to 10 mg i.v.) and perphenazine (1.2 to 2.0 mg i.v.) was associated with less PONV (OR = 0.3, p = 0.005). Type of local anesthetic used for lumbar plexus block was not associated with PONV incidence., Conclusions: For ACL reconstruction with regional anesthesia, use of LUM-SCI was associated with a higher rate of PONV, whereas combination antiemetic prophylaxis with perphenazine and dexamethasone was associated with less PONV.

Post-operative nausea and vomiting is a major problem for patients following cardiac surgery. The literature in this area identifies that there are a number of individual patient and post-operative factors which increase the risk of post-operative nausea and vomiting, including female gender, non-smoker, age, use of opioids, pain and anxiety. An audit involving 200 patients, who had undergone cardiac surgery was implemented to assess/evaluate the incidence of nausea and vomiting for this patient group. Data collected included information relating to nausea and vomiting, pain, consumption of morphine and other individual patient variables. The results suggest that nausea and vomiting, is experienced by a large number of patients after cardiac surgery (67%), with the majority suffering on the first day after surgery. The duration of nausea and vomiting for most is short, but for a significant number (7%) it can last up to one-quarter of their initial post-operative course. The paper discusses key implications for practice arising from this project.

Anecdotal reports support research findings in documenting the high incidence of negative postoperative outcomes after gynecologic (GYN) laparoscopic surgery. Three outcome measures, postoperative pain, postoperative nausea and vomiting (PONV), and length of stay, have received considerable attention. Two nursing interventions frequently suggested for their positive effects are guided imagery and music therapy. An experimental pilot study was conducted to determine the effects of these nursing inventions on postoperative pain, PONV, and length of stay for GYN laparoscopic patients (n = 84). During the perioperative period, patients were randomly assigned to one of 3 interventions: guided imagery audiotapes (GI), music audiotapes (MU), or standard care (C), and outcome measures were evaluated. Results indicated that patients in both the guided imagery and music groups had significantly less pain on PACU discharge to home than the patients in the control group. These findings suggest that both guided imagery and music are effective strategies in improving pain, a difference that becomes apparent when the patient is ready to be discharged. It is possible that these interventions act as distractions in reducing the report of negative postoperative outcomes.

Postoperative nausea and vomiting (PONV), a common complication after anesthesia and surgery, often results in delayed discharge with the patient's unpleasant symptoms continuing at home. To effectively prevent and treat PONV, it is important to understand the factors implicated in PONV, the mechanisms of PONV, the pharmacology of the antiemetic agents, and the nonpharmacologic measures that have been shown to be effective. The cause of PONV is likely to be multifactorial, with important predictors being female gender, history of PONV, and history of motion sickness. The vomiting center can be triggered by activation of dopamine, serotonin (type 3), histamine (type 1), and muscarinic cholingergic receptors in the chemoreceptor trigger zone and the nucleus tractus solitarus, as well as acetylcholine receptors in the vestibular apparatus, vagal afferents from the periphery, and the endocrine environment. Antiemetic agents such as the serotonin antagonists (eg, ondansetron, dolasetron), droperidol, antihistamines (eg, diphenhydramine, dimenhydrinate), and promethazine can prevent and treat PONV effectively. Transdermal scopolamine and dexamethasone have a role in the prevention of PONV, particularly for certain high-risk patients. Nonpharmacologic measures and alternative treatments such as hydration, maintaining blood pressure, acupressure techniques, trancutaneous acupoint stimulation, and isopropyl alcohol must not be overlooked. Finally, an evidence-based algorithm for the prevention and treatment of PONV in adults is presented., (Copyright 2002 by American Society of PeriAnesthesia Nurses.)

Predicting which patients will experience postoperative nausea and vomiting is difficult. Prophylactic antiemetic administration has been shown to reduce unplanned admission after day case surgery. In published comparative studies of antiemetic efficacy, droperidol has been considered to be the 'gold standard' against which other agents are measured. The recent withdrawal of droperidol due to reports of cardiac arrhythmias and the potential for sudden death has left a vacancy for a safe and effective antiemetic. This article explores the published literature for alternatives to droperidol as a single dose or prophylaxis in patient controlled analgesia devices.
