Obesity has become increasingly prevalent in the United States. Bariatric surgeries have increased as the prevalence of obesity has risen, providing an effective alternative to weight loss. Intravenous acetaminophen (IVA) is a safe and effective non-opioid medication that can be given without the risk of respiratory or cardiac complications. Research has shown that the use of IVA during surgery can improve postoperative pain scores, reduce opioid requirements, and improve patient satisfaction.

A retrospective cohort study of 200 patients (100 per group) undergoing laparoscopic bariatric surgery (LBS) was performed. Statistical analysis was used to determine the relationship between those who received IVA near anesthesia induction or near end of surgery and intraoperative/postoperative opioid consumption and pain scores. Other study variables included: age, gender, American Society of Anesthesiologists (ASA) classification, Body Mass Index (BMI), and length of anesthesia (LOA).

The results of the study determined there was no significant relationship between the administration time of IVA and intraoperative/postoperative opioid consumption or pain scores. There were significant relationships found between IVA administration time and BMI, age, and LOA.

While no significant relationships were found related to the administration timing of IVA and opioid consumption and pain scores, many studies have found efficacy in the use of IVA in reducing opioid consumption and pain scores in a variety or procedures and populations. Although this study did not provide results influencing the administration timing of IVA, it is recommended that other studies follow a similar study design in further investigation into the use of IVA to enhance anesthesia care and improve patient safety.
