A recent randomized clinical study published in Research and Innovation in Anesthesia in February 2026 reveals that clinicians can dramatically cut postoperative nausea and vomiting (PONV) from 27.5% to just 10.1%. Finding a universally effective treatment for the high rates of postoperative nausea and vomiting (PONV) in laparoscopic surgeries remains a clinical challenge. Therefore, a randomized clinical study of 138 adults undergoing elective laparoscopic surgery compared the use of intravenous palonosetron alone to a palonosetron-dexamethasone combination. The study primarily evaluated their effects on the incidence of postoperative nausea and vomiting (PONV) alongside the need for rescue antiemetics.
