Abstract

Objectives: To evaluate the effect of postoperative analgesia using a mixture of fentanyl combined with nefopam and granisetron patient-controlled analgesia (PCA) after tonsillectomy and uvulopalatopharyngoplasty. Methods: Prospective study on 30 patients who underwent tonsillectomy and uvulopalatopharyngoplasty who were treated with intravenous patient-controlled analgesia using fentanyl 5mcg/ml solution combined with nefopam 0.5mg/ml and granisetron 0.01mg/ml. Patients received a background dose of 2ml/h and a bolus dose of 1ml. The lockout interval was set at 60 minutes. Visual Analogue Scale evaluated pain and monitored pulse, blood pressure, respiratory rate, and SpO2 three consecutive days after surgery. Rescue analgesia was administered with 1g Paracetamol if there was a response after three consecutive presses, but the VAS score was still ≥ 4. Results: 100% of patients had mild or medium pain (VAS score <4) at rest; 90% had a VAS score <4 when coughing. Side effects included sweating 6.67%, nausea, and vomiting 13.33%, while no patients had hypotension or respiratory failure. Conclusion: Patient-controlled intravenous analgesia reduced pain well after tonsillectomy and uvulopalatopharyngoplasty. Adverse effects include sweating, nausea, and vomiting, no patients with hypotension, and respiratory failure.
