Brief summary

This randomized controlled study will compare narcotic consumption between two groups: patients that receive a perioperative dose of IV acetaminophen versus patients that receive a perioperative dose of oral liquid acetaminophen for scheduled cesarean section.

Detailed description

Enhanced recovery is an alternate management protocol described by a multi-modal, evidence based approach to peri-operative care, with the goal of accelerating recovery and return to normal activity after surgery. Results have shown stable pain control with a decrease in narcotic consumption, a quicker return of bowel function, and decreased length of hospital stay and cost with no change in level of patient satisfaction, morbidity, or readmission rate. An aspect of some alternate management protocols is the administration of acetaminophen. The concentration of acetaminophen in cerebrospinal fluid (CSF) is directly proportional to the analgesic activity of acetaminophen. Acetaminophen relies on a high concentration gradient from the plasma to the CSF in order to passively diffuse into the central nervous system (CNS), its principal site of action. A 2012 study, comparing plasma and CSF pharmacokinetics of intravenous (IV), oral (PO), or rectal (PR) acetaminophen, concluded that IV administration of acetaminophen results in higher plasma and CSF concentration values. Therefore, IV acetaminophen produces better CNS penetration compared to PO or PR methods.

Masking description

When the Principal Investigator calls to enroll patient into the study, pharmacy will be responsible for labelling and delivering the drugs to the labor and delivery unit. The label will include the patient enrollment number and the study name. The investigators will be blind to the patient's drug/placebo assignment. In case of emergency, side effects, or allergic reaction, the pharmacy will be contacted to unblind medication.

Inclusion criteria

* Women age 18 or older * Scheduled to undergo a cesarean section

Exclusion criteria

* Existing diagnosis of chronic pain * Need to undergo a vertical skin incision * Aspartate Aminotransferase (AST) \> 50, alanine aminotransferase (ALT) \> 70 * Platelets below 80,000 on admission * Need to undergo general anesthesia * Tubal ligation at time of Cesarean section * Prior or known allergy to any of the medications being utilized in this study

Design outcomes

Primary

MeasureTime frameDescription
Narcotic Utilization6 hours post operativeThe Center for Disease Control and Prevention Morphine Milligram Equivalent Score will be used to calculate total narcotic use (conversion factor for administered opioid x milligrams administered) while the patient remains as an inpatient.

Secondary

MeasureTime frameDescription
Post-operative Pain LevelEvery hour for six hours post-opPain will be measured via the visual analog Postoperative Pain Scale and gathered by nursing. The visual analogue Postoperative Pain Scale indicates the level of pain the patient is feeling or felt in the indicated period from 0 (no pain) to 100 (the worst pain possible).
Patient SatisfactionUp to 24 hoursPatient satisfaction will be assessed using the validated survey used in the Mayo Clinical Trial.
Postoperative complications during the inpatient stayUp to 24 hoursPostoperative complications will be noted during the inpatient stay.
