Does intra-operative 80% supplemental oxygen reduce postoperative nausea and vomiting in adult patients undergoing elective procedures with high PONV risk?
Supplemental intra-operative oxygen (80%) does not reduce postoperative nausea and vomiting compared to 30% oxygen, regardless of endpoint, observational period, or site of surgery.
No takes yet. Share an insight, caveat, or question.
Supplemental 80% oxygen does not reduce PONV; challenges prior trials and does not support its use for prophylaxis in high-risk patients.
Turan et al. (2006) studied this question.
