The Opioid-sparing Effect and Reduced PONV Using Propacetamol in PCA Among Patients With High Risk of PONV

While Patient-controlled analgesia (PCA) has the advantage of effectively reducing the degree of postoperative pain, it can also affect the patient's outcome by several adverse effects such as postoperative nausea and vomiting (PONV). Especially for high risk group of patients for PONV, the ideal regimen for sufficient analgesia with minimal adverse effect needs to be sought. Propacetamol is known for its effective, rapid analgesia, opioid-sparing effect, and is used widely for post operative pain management. This study aims to see the opioid-sparing effect and the degree of PONV when propacetamol is added to PCA for high risk PONV patients.
