Outcome Measures

Primary Outcomes (1)

  • Post-Operative Opioid Requirement

    Opioid Consumption will be monitored in the first 24 post-operative hours. All non-opioid analgesics are disallowed. Total opioid consumption was calculated based on morphine equivalents (MEs), where 1 mg of IV morphine was equivalent to 1 ME, and 1 mg IV hydromorphone was calculated as 7 MEs.

    24 hours post-operatively

Secondary Outcomes (4)

  • Post-Operative Pain

    24 Hours Post-Operatively

  • Post-Operative Side Effects

    24 Hours Post-Operatively

  • Time to Extubation at Emergence From Anesthesia

    Time from of discontinuation of anesthetic to time of extubation, an average of 7 minutes

  • Time for Patient to Meet Post-anesthesia Care Unit (PACU) Discharge Criteria

    From time of entry to PACU to time to meet PACU discharge criteria, an average of 12 minutes

Study Arms (2)

Intravenous Acetaminophen

EXPERIMENTAL

Patients will be receive doses of 1000 mg/100 mL of IV Acetaminophen (OFIRMEV). The drug will be infused over 15 minutes.

Drug: Acetaminophen

Placebo

PLACEBO COMPARATOR

Patients will be given 100 mL normal saline placebos at scheduled time intervals in place of IV acetaminophen.

Drug: Placebo

Interventions

Intravenous Acetaminophen, 1000 mg/100mL, Every 6 hours, Infused over 15 minutes.

Also known as: OFIRMEV
Intravenous Acetaminophen

100 mL 0.9% Sodium Chloride

Limitations and Caveats

Not powered to detect differences in pain score. Patients were not given a patient-controlled analgesia device; rather, administration of morphine was dependent on nurse administration.
