Better beyond 24 hours?
Palonosetron + dexamethasone reduced late PONV vs ondansetron combo—while early outcomes were similar.

🤢 Nausea and vomiting during caesarean delivery are not trivial. Multimodal antiemetic prophylaxis, especially combination therapy, can reduce complications, improve comfort, and support smoother recovery.

Have you read our paper in Obesity Surgery?
36% experienced #PONV at #PACU after #BariatricSurgery. Major differences between hospitals. Can we learn from the best?

Happy to present our registry study on PONV after bariatric surgery. Incidences are very high. We have a challenge to reduce the numbers… #ponv #anesthesia #pacu #bariatricsurgery @JournalObesity @SPORevent

Genetics did not have any relevant predictive value for PONV in this very well conducted study. Also, they report an incidence of 8.8% for PONV at PACU confirming my thesis that in a general PACU cohort, one in ten experience PONV. #ponv #anesthesia #postoperative #pacu

Postoperative nausea and vomiting is a key driver of unplanned admission and patient satisfaction after surgery. In the January 2025 cover study, Douville et al. hypothesized that genetics may contribute to the overall risk of this complication: https://t.co/JzI8cySteQ

Interesting study, but main outcome is not relevant (patients with BOTH nausea AND vomiting at 24 hours). A real outcome is in the results: the overall number of events of nausea at 24 h were 82% (47/57) and 89% (51/57), and of vomiting were 26% (15/57) and 19% (11/57).

Interesting review on the use inhaled isopropyl alcohol to treat #PONV. Many substances relive PONV, but it is always a balance between effect and side-effects before an intervention can be recommended for PONV.

RCT with low-dose nicotine patch do not reduce #PONV.
Abstract indicate a signal in the need for rescue analgesics (meperidine) (72% vs 48%), but figures wrong! Should be 52% vs 48% according to table 3.
Important to always read the whole article!

Case closed. High O2 do not reduce #PONV. @noponv

[Anesthesiology Journals @_Anesthesiology]

“High intraoperative oxygen administration has no clinically significant benefit on the incidence of postoperative nausea and vomiting.” Authors assert that intraoperative oxygen should be adjusted for oxygenation reasons only. See the editorial: https://t.co/NephZ9Nk30

Systematic #PONV assessments reduces #PONV. New study in @JNCQonline by Pratt et.

[Nursing Care Quality @JNCQonline]

PONV is a substantial cause of increased length of stay, cost of care, & unanticipated patient admission & readmission.

#PONV risk is among the highest for laparoscopic bariatric surgery. EP needle stimulation reduced PONV, still high incidences 0-12 h in both groups (70 vs. 90%) @JournalObesity. Same effect of the needle with a more aggressive antiemetic regime? @noponv
