A COMPARATIVE STUDY ON EFFECT OF FENTANYL WITH PROPOFOL AND FENTANYL WITH DEXMEDETOMIDINE AS INTRAVENOUS ANAESTHETICS FOR UPPER GI ENDOSCOPY

Progress in research of postoperative nausea and vomiting after painless gastrointestinal endoscopy

Postoperative nausea and vomiting (PONV) refers to nausea and vomiting occurring within 24 h after surgery. PONV seriously affects the quality of postoperative recovery after painless gastrointestinal endoscopy. In this paper, we review the progress in the research of PONV after painless gastrointestinal endoscopy to provide clinical guidance for improving the medical safety and service quality of painless and comfortable anesthesia. PONV after painless gastrointestinal endoscopy has unique factors and characteristics. On the basis of comprehensive evaluation and according to the patient's specific situation, the doctors should identify the risk factors, optimize the anesthesia scheme, choose anesthetics and analgesics rationally, and take comprehensive diagnostic and therapeutic measures.
