Background: Total hip arthroplasty (THA) causes extensive tissue damage and severe pain. This study aimed to assess the analgesic efficacy, adverse effects (AEs), and safety of continuous intravenous (iv) oxycodone infusion with ketoprofen (injected into the iv line) in patients after THA, and to assay serum oxycodone levels.
Patients and methods: Fourteen patients, aged 59â€’82 years with American Society of Anesthesiologists (ASA) classification I or III, underwent THA with intrathecal analgesia and sedation induced by iv propofol. After the surgery, oxycodone (continuous iv infusion) at a dose of 1 mg/h (five patients) or 2 mg/h (nine patients) with 100 mg ketoprofen (injected into the iv line) was administered to each patient every 12 h. Pain was assessed using a numerical rating scale (NRS: 0 – no pain, 10 – the most severe pain) at rest and during movement. AEs, including hemodynamic unsteadiness, nausea, vomiting, pruritus, cognitive impairment, and respiratory depression, were registered during the first 24 h after surgery.
Results: Oxycodone (continuous iv infusion) at a dose of 2 mg/h with ketoprofen (100 mg) administered every 12 h provided satisfactory analgesia in all nine patients without the need of rescue analgesics within the first 24 h after THA. In three out of five patients, oxycodone at 1 mg/h was effective. Oxycodone did not induce drowsiness, vomiting, pruritus, respiratory depression, or changes in blood pressure. Bradycardia appeared in two patients, and nausea was observed in one patient.
Conclusion: Oxycodone infusion with ketoprofen administered by iv is effective in patients after THA. Intravenous infusion of oxycodone is a predictable, stable, and safe method of drug administration.
