Perioperative Systemic Acetaminophen to Improve Postoperative Quality of Recovery After Ambulatory Breast Surgery
Study Details
Study Description
Brief Summary
Recent evidence demonstrates that perioperative pain continues to be poorly managed among ambulatory surgical patients. More importantly, few interventions that minimize postoperative pain have also shown to improve patient overall quality of post-surgical recovery. Ketorolac has been used to minimize perioperative pain despite the lack of evidence for its use when administered as a single dose preventive strategy.Ketorolac has also been associated with a higher incidence of perioperative hematomas and the need for surgical re-exploration after breast surgery.
Systemic acetaminophen has become recently available in The United States. In contrast to ketorolac, systemic acetaminophen has not been reported to have adverse side effects on patients undergoing breast surgery. Although evidence suggests that a single dose perioperative acetaminophen reduces postoperative pain, it remains unknown if a single dose intravenous acetaminophen improves postoperative quality of recovery after ambulatory surgery.
The main objective of the current investigation is to evaluate the effect of a single dose systemic acetaminophen on postoperative quality of recovery after ambulatory breast surgery. We also seek to determine if systemic acetaminophen would decrease postoperative pain and the time to hospital discharge in the same population.
Significance: The current project evaluates a potential intervention to improve perioperative pain and recovery after ambulatory breast surgery. Postoperative pain in the ambulatory surgical patients has been shown consistently to be poorly managed.

Detailed Description
Patients will be recruited up to the day of surgery. They will be then randomized using a computer generated table of random numbers to two groups: Group A (IV acetaminophen 1000 mg over 15 minutes at the start of surgical closure) and Group B (placebo group-same volume of saline solution administered in the same fashion).This dose has been commonly used in other studies involving IV acetaminophen.6 Both drugs will be identical and will be prepared by hospital pharmacy. After placement of standard ASA monitors, induction will be performed with 0.1mcg/kg/min of remifentanil IV, propofol 1.5-2.5 mg/kg IV and succinylcholine 1-2 mg/kg IV. Tracheal intubation will be performed using a MAC 3 blade and a size 7 endotracheal tube. Maintenance will be achieved with remifentanil infusion titrated to keep the blood pressure within 20% of baseline values and sevoflurane titrated to keep a bispectral index monitor between 40 and 60. Patients will receive ondansetron 4mg IV and dexamethasone 4 mg IV for postoperative nausea and vomiting prophylaxis. In the recovery room patients will receive hydromorphone IV in divided doses to keep pain <4/10(scale where 0 means no pain and 10 is the worst pain) and metoclopramide 10 mg IV as rescue antiemetic. Data will be collected by a research assistant blinded to the group allocation. Data collected will involve pain at PACU arrival (NRS-0-10), presence of nausea and vomiting, severity of nausea and vomiting, total opioid consumption in PACU, time to discharge using a Modified Postanaesthetic Discharge Scoring System (MPADSS) 9, total opioid consumption 24 hours, QoR40 24hours after surgery.8

Outcome Measures
Primary Outcome Measures
- Quality of Recovery at 24 Hours(QoR-40 Instrument) [24 hours after the surgical procedure]
Quality of recovery score 24 hours after the surgical procedure. Total score range of 40 (poor recovery) and a score of 200 (good recovery).
Secondary Outcome Measures
- Postoperative Opioid Consumption [24 hour]
Postoperative opioid consumption over 24 hours. Converted into oral mg of morpine equivalents.
- Postoperative Pain in the Post Anesthesia Care Unit [Time in the post anesthesia care unit after surgery (average of 5 hours)]
Postoperative pain within the post anesthesia care unit after surgery. Area under the numeric rating scale for pain versus time curve in the post anesthesia care unit (score * min).Numeric rating scale for pain on a scale of 0-10 (0 is no pain and 10 is high pain) versus time curve in the post anesthesia care unit ( score * min). Area under a curve units of the horizontal axis multiplied by the units of the vertical axis. A higher value indicates more pain and time in the Post Anesthesia Care Unit.The range is 0 pain to x time in minutes x 1 hour to 5 hour ( 60-300 minutes) . The pain scores were collected at 15 minute intervals from the time of admission to the PACU. The area under the NRS pain scale versus time curve was calculated using the trapezoidal method as an indicator of pain burden during early recovery (Graph Pad Prism ver 5.03, Graph Pad Software INC.
