简要总结
Number of patients with unsatisfactory pain relief defined as average visual analog scale (VAS) more than 5 with or without requirement of IVPCA for pain relief during the first 48 hours postoperative period will be compared between the two groups and form the primary outcome for the study. Postoperative pain intensity will be measured by Visual Analog Scale (VAS) with 0- being no pain and 10-being maximum pain and the analgesic efficacy in both groups will also be evaluated by the amount of total narcotic consumption (measured with IV morphine equivalent doses of analgesics used to provide pain relief).
详细描述
In response to an increased focus on improving patient outcomes and satisfaction with surgical care, a growing body of clinical evidence has recently been dedicated to enhanced recovery after surgery (ERAS) protocols. These evidence-based perioperative pathways aim to optimize patients undergoing surgery in the preoperative, intraoperative, and postoperative periods. ERAS protocols have incorporated the use of multimodal analgesia to minimize the use of intra- and postoperative opioid analgesics. Lidocaine, ketamine, magnesium, gabapentin, acetaminophen and non-steroidal anti-inflammatory drugs are some of the adjuvant analgesics used in combination with regional blocks to optimize analgesia and recovery. Multimodal analgesia has dependably been shown to significantly reduce postoperative opioid requirements as well as opioid-related side effects such as postoperative nausea and vomiting. Both oral and intravenous acetaminophen preparations have been shown to be useful adjuvants in multimodal analgesia. Intravenous acetaminophen has been of interest for its utility in post-surgical patients, who have not yet been cleared for oral intake. Intravenous acetaminophen should also be preferred over oral acetaminophen in patients after major abdominal surgery where absorption of medications given through oral route is erratic. Although the efficacy of intravenous acetaminophen as a postoperative pain adjunct is known, its exact role in ERAS protocols and non-narcotic multimodal analgesic regimens for major abdominal surgery has not been studied in randomized clinical trials to define its efficacy. The primary goal of this study is to assess the utility of a postoperative intravenous acetaminophen dosing schedule in minimizing postoperative pain, opioid consumption and opioid-related side effects. We also aim to study overall patient satisfaction and cost-effectiveness (direct and indirect costs) of this regimen as part of ERAS protocol at a large tertiary medical center.

结局指标
主要结局
Postoperative Pain Intensity
时间窗: PACU admission every thirty minutes until discharge to the floor and thereafter every four hours for first 24-hour, then every six hours until 48 hours and then every twelve hours until 72 hours postoperatively.
Number of patients with unsatisfactory pain relief defined as average numeric rating scale (NRS) more than 5 will be compared between the two groups. This may include patients using IVPCA for pain relief during the first 48 hours postoperative.
次要结局
- Time to Readiness for Discharge From Post Anesthesia Care Unit (PACU)(From time of PACU admission until the time of discharge, assessed up to 24 hours postoperatively)
- Total Post-operative Narcotic Consumption(From time of PACU admission until the time of discharge and 72-hours postoperatively, whichever comes first)
- Number of Participants With Readmission to the Hospital(From the time of consent until 30 days post-operatively)
- Patient Satisfaction(These measurements will be taken at time of discharge up to 30 days, whichever comes first)
- Intensive Care Delirium Screening Checklist (ICDSC)(The delirium scores will first be measured every 12 hours for 72 hours after surgery.)
- Post-operative Nausea(These will be evaluated from the time of PACU admission until 72 hours postoperatively.)
- Post-operative Emesis(These will be evaluated from the time of PACU admission until 72 hours postoperatively.)
- SF-12 Health Survey(These measurements will take place at 30-days post hospital discharge)
- Time to Bowel Movement(From time patient left operating room until the time of first documented bowel movement, assessed up to hospital discharge)
- Time to Oral Intake(From date of randomization until the date of first documented oral intake, assessed up to 72 hours postoperatively)
- Time to Ambulation(From date of PACU admission until the date of first documented ambulation, assessed up to 72 hours postoperatively)
- Time to Hospital Discharge(From date of randomization until the date of hospital discharge or 30 days postoperatively, whichever comes first)
