Nausea and vomiting management
Research Guide
What is Nausea and vomiting management?
Nausea and vomiting management is the prevention and treatment of postoperative nausea and vomiting (PONV) and chemotherapy-induced nausea through interventions such as antiemetic therapy, neurokinin-1 antagonists, dexamethasone, and acupuncture, guided by consensus guidelines to improve patient outcomes.
The field encompasses 28,560 works focused on PONV prevention and management, including risk assessment and multimodal interventions. Apfel et al. (1999) introduced a simplified risk score for predicting PONV, validated across centers using logistic regression. Gan et al. (2013) provided consensus guidelines updating prior sets from 2003 and 2007 based on multidisciplinary expert input.
Topic Hierarchy
Research Sub-Topics
Postoperative Nausea Risk Prediction Scores
This subtopic covers development and validation of risk scores like Apfel score for PONV incidence. Researchers study multifactorial models, machine learning predictors, and patient stratification.
Antiemetic Prophylaxis Multimodal Strategies
This subtopic examines combination therapies including 5-HT3 antagonists, dexamethasone, and droperidol. Researchers conduct factorial trials, dose-response analyses, and risk-adapted regimens.
Chemotherapy-Induced Nausea Neurokinin-1 Antagonists
This subtopic focuses on NK1 receptor antagonists like aprepitant for delayed CINV phases. Researchers evaluate triple therapy regimens, pharmacokinetics, and long-term adherence.
Postoperative Nausea Consensus Guidelines
This subtopic reviews iterative consensus processes updating PONV management recommendations. Researchers synthesize meta-analyses, GRADE assessments, and implementation barriers.
Non-Pharmacological PONV Interventions
This subtopic investigates acupuncture, P6 stimulation, and aromatherapy for PONV prevention. Researchers perform RCTs, mechanism studies, and cost-effectiveness analyses.
Why It Matters
Effective nausea and vomiting management enhances postoperative recovery and patient satisfaction by reducing complications that delay discharge and increase readmissions. Apfel et al. (2004) demonstrated in a factorial trial of six interventions—droperidol, dexamethasone, a tropisetron-droperidol combination, propofol infusion, and nitrogen or bimodality prophylaxis—that combining independent antiemetic actions reduces PONV incidence, with multiple interventions reserved for high-risk patients. Gan et al. (2020) updated consensus guidelines for adult and pediatric populations, emphasizing evidence-based care under the American Society of Enhanced Recovery to address PONV as a common barrier to fast-track surgery, as outlined by Kehlet and Wilmore (2008) who integrated multimodal rehabilitation for optimized outcomes. Watcha and White (1992) highlighted PONV as a significant issue in ambulatory surgery, where morbidity affects health outpatients despite low actual harm.

Where to Start
"A Simplified Risk Score for Predicting Postoperative Nausea and Vomiting" by Apfel et al. (1999), as it provides a foundational, validated tool for identifying at-risk patients before exploring interventions.
Key Papers Explained
Apfel et al. (1999) established a risk score building the foundation for prophylaxis; Apfel et al. (2004) tested six interventions in a factorial trial, showing independent effects and multimodal benefits; Gan et al. (2013) synthesized these into consensus guidelines updating prior versions; Gan et al. (2020) refined them further for adults and pediatrics; Watcha and White (1992) contextualized PONV's clinical significance in ambulatory settings.

Advanced Directions
The fourth consensus guidelines by Gan et al. (2020) represent the current standard, expanding to pediatric care and enhanced recovery protocols, with no recent preprints or news indicating ongoing refinements in risk models or novel antiemetics.

Frequently Asked Questions
What risk factors predict postoperative nausea and vomiting?
Apfel et al. (1999) developed a simplified risk score for PONV using female gender, history of motion sickness or PONV, nonsmoking status, and postoperative opioid use, validated across centers. The score simplifies logistic regression coefficients without substantial loss of accuracy. Risk increases multiplicatively with each factor present.
What interventions prevent postoperative nausea and vomiting?
Apfel et al. (2004) conducted a factorial trial showing droperidol, dexamethasone, tropisetron-droperidol combination, propofol infusion, and nitrogen reduce PONV independently. Single interventions suit moderate-risk patients, while multiple are for high-risk cases. Prophylaxis is rarely needed for low-risk patients.
What do consensus guidelines recommend for PONV management?
Gan et al. (2013) compiled multidisciplinary guidelines updating 2003 and 2007 versions with recent PONV data. Gan et al. (2020) issued fourth consensus guidelines for adults and pediatrics, established by an international panel under the American Society of Enhanced Recovery. Both emphasize evidence-based antiemetic strategies.
How does PONV impact postoperative recovery?
Watcha and White (1992) described PONV as the 'big little problem' in ambulatory surgery, unavoidable without intervention despite low morbidity. Kehlet and Wilmore (2008) integrated PONV management into fast-track surgery via multimodal rehabilitation. Apfelbaum et al. (2003) surveyed 250 US adults, finding 80% experienced postoperative pain, with 86% moderate to extreme among them, underscoring undermanagement linked to nausea.
What role do neuraxial techniques play in PONV reduction?
Rodgers et al. (2000) overviewed randomized trials showing epidural or spinal anaesthesia reduces postoperative mortality and morbidity compared to general anaesthesia. Benefits may stem from avoiding general anaesthesia or direct neuraxial effects. Further research clarifies the extent of these reductions.
How have PONV guidelines evolved?
Gan et al. (2013) updated prior guidelines from 2003 and 2007 with new data. Gan et al. (2020) released the fourth consensus, covering adult and pediatric care via international expert consensus. Updates reflect accumulating evidence on antiemetics and risk stratification.
Open Research Questions
- ? How can PONV risk scores be further simplified for real-time clinical use without losing predictive power?
- ? What is the optimal combination of antiemetics for high-risk patients beyond the six interventions tested?
- ? Do benefits of neuraxial blockade on PONV derive solely from avoiding general anaesthesia?
- ? How do PONV management strategies integrate with fast-track surgery protocols for diverse patient populations?
- ? What pediatric-specific factors require adjustments in consensus PONV guidelines?
