Efficacy of Intravenous Acetaminophen in Periimplantation Pain of Cardiac Electronic Devices: A Randomized Double-Blinded Study
Although intravenous acetaminophen has been administered to reduce postoperative pain, it has not been used during cardiac implantable electronic devices (CIEDs) implantation.Design
This was a randomized double-blinded interventional study.Methods
Thirty-two patients who were referred for new CIED implantation during July 2012 until April 2013 randomly received placebo or 1 g of intravenous acetaminophen. All patients were treated with local anesthesia. Pain score during incision, pocket creation, and in the recovery room, and the patients' need for analgesics during the 6 hours after the procedure were recorded in both groups.Findings
Seventeen and 15 patients received acetaminophen and placebo, respectively. Pain scores in patients treated with acetaminophen were significantly lower (4.4 vs 2.9, P = .004), and they received less analgesics (17% vs 60%, P = .014).Conclusions
Intravenous administration of acetaminophen is effective for pain relief in patients undergoing CIED implantation and decreases the need for postoperative analgesics.
