Antiemetic Prophylaxis With Fosaprepitant and Ondansetron in Patients Undergoing Thoracic Surgery

Postoperative nausea and vomiting (PONV) is a common postoperative complication of general anesthesia. The antiemetic 5-serotonin 3 (5-HT 3) receptor antagonist is widely used in postoperative anti-emesis,However, more clinical studies are needed to confirm whether neurokinin-1 (NK-1) receptor antagonists have better effects on PONV than 5-HT 3 receptor antagonists.We aimed to evaluate the effects of NK-1 receptor antagonists and 5-HT 3 receptor antagonists on PONV through a randomized controlled study. To this end, we took patients undergoing thoracic surgery as the research object, they received an antiemetic prophylaxis with ondansetron or fosaprepitant, and the frequency of postoperative nausea and vomiting the of the two antiemetic prophylaxis regimens were analyzed, and the occurrence of pulmonary complications, length of hospital stay, the nutrition and quality of life after surgery administration were also compared. Through this clinical trial, we hope to obtain a better antiemetic prophylaxis regimen and provide clear information for patients and physicians to guide clinical decisions that enhance treatment efficacy and reduce the occurrence of side effects.
