This prospective randomized study shows that high-concentration oxygen reduces nausea and vomiting in recovery, suggesting improved postoperative care.
High-concentration oxygen therapy, compared to low-concentration therapy, reduce postoperative nausea, vomiting, and pain during early recovery, without affecting hemodynamic parameters or respiratory stability, providing evidence-based guidance for optimizing postoperative oxygen therapy.
