Rationale

Among the reviewed high and moderate quality randomized clinical trials, eleven studies reported on complications related to the administration of acetaminophen.[2-6, 12, 13, 15-18] Qualitative examination demonstrated no consistent difference between IV acetaminophen, oral acetaminophen, and placebo. Direct meta-analysis was only capable of being performed for IV acetaminophen, which showed no significant difference with regards to any complication (0.98 relative risk; 95% confidence interval of 0.83 to 1.16) or vomiting (1.16 relative risk; 95% confidence interval of 0.30 to 4.45). Therefore, IV and oral acetaminophen are considered to be safe analgesic medications to administer during the perioperative episode of a primary TJA.
