Experimental: Intravenous Acetaminophen
Patients will be receive doses of 1000 mg/100 mL of IV Acetaminophen (OFIRMEV). The drug will be infused over 15 minutes.
Intravenous Acetaminophen, 1000 mg/100mL, Every 6 hours, Infused over 15 minutes.
Other Name: OFIRMEV
Placebo Comparator: Placebo
Patients will be given 100 mL normal saline placebos at scheduled time intervals in place of IV acetaminophen.
100 mL 0.9% Sodium Chloride
Other Name: 0.9% Sodium Chloride
- Post-Operative Opioid Requirement [ Time Frame: 24 hours post-operatively ]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.
- Post-Operative Pain [ Time Frame: 24 Hours Post-Operatively ]Patients will be assessed for pain using a Visual Analogue Scale (VAS) Scale at set time points after surgery (0,1,2,4,8,12,16,20,24 hours post-operatively). The Visual Analogue Scale (VAS) scale was measured on a scale of 0 - 10 (0 = no pain, 1-3 = mild, 4-6 = moderate, 7-10 = severe). Higher values on the VAS represent a worse outcome. The two rows below report: 1. the average VAS score for the least amount of pain reported per group and 2. the average VAS score of the worst amount of pain reported per group.
- Post-Operative Side Effects [ Time Frame: 24 Hours Post-Operatively ]Patients will be monitored for 24 hours post-operatively to detect the incidence of any drug or opioid-related side effects. These side effects were not considered to be adverse events.
- Time to Extubation at Emergence From Anesthesia [ Time Frame: 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 [ Time Frame: From time of entry to PACU to time to meet PACU discharge criteria, an average of 12 minutes ]
