ReviewClinical and economic burden of postoperative nausea and vomiting: Analysis of existing cost data.
Postoperative nausea and vomiting (PONV) is an undesirable outcome that occurs in up to 30% of patients. Over the years, the cost of treating PONV has decreased due to the availability of cheaper yet effective antiemetics. Limiting PONV development benefits the hospital system as studies have shown that prevention is associated with shorter post-anesthesia care unit (PACU) stays as well as decreased supply costs and staffing burden. ⋯ Studies have also shown that prevention of initial development of PONV limits readmission rates, which is beneficial to both the patient and the hospital. Owing to recent economic analysis and reductions in antiemetic prices, the patient's preference for comfort, the hospital's commitment to providing the best care, and the system's desire for fiscal prudence are aligned. This culminates in recommending PONV prophylaxis for all patients undergoing anesthesia.

Editorial ReviewNew insights into the pathophysiology and risk factors for PONV.
Postoperative nausea and vomiting (PONV) affects patient outcomes and satisfaction. New research has centered on evaluation of post-discharge and opioid-related nausea and vomiting. Mechanical and drug effects stimulate the release of central nervous system neurotransmitters acting at receptors in the vomiting center, area postrema, and nucleus of the solitary tract. ⋯ Pharmacogenetics plays a role in gene typing as antiemetic medication metabolism results in varying drug effectiveness. Risk scoring systems are available. Individualized multimodal plans can be designed as part of an enhanced recovery after surgery protocol.

ReviewAn update on the management of PONV in a pediatric patient.
Postoperative nausea and vomiting (PONV) is a major cause of patient dissatisfaction following anesthesia. The difficulty in diagnosing nausea in much of the pediatric population has led to an emphasis on anti-emetic prophylaxis for all. ⋯ New antiemetics emerging from other medical disciplines, particularly oncology, may have potential use in prophylaxis and treatment of nausea and vomiting in the pediatric surgical population. New agents, many of which have a long duration of action, will augment the anesthesiologist's ability to adequately prevent PONV, and to treat persistent nausea and vomiting that extend beyond the immediate post-operative period.

Postdischarge nausea and vomiting (PDNV) occurs in at least 30% of patients leaving hospital, especially after day-case surgery. A significant number of ambulatory patients may develop PDNV associated with the use of analgesics for postsurgical pain. A validated PDNV prediction score and international evidence-based consensus guidelines for PONV/PDNV management are available. ⋯ Patient education is often overlooked in this context. All clinicians involved in the ambulatory surgery care process should participate in the development of institutional protocol for PONV/PDNV management. Constant quality control and patients' feedback should be integrated as part of an efficient implementation strategy.
