Experimental: Opioid-free Anesthesia
Patients will receive no intraoperative narcotics as part of their anesthesia regimen
|
Drug: Opioid-free Anesthesia
Doses/concentration of medications/agents used for the anesthetic management of the subjects enrolled in this trial may be adjusted when necessary to provide optimal subject care. Acetaminophen 1g will be given prior to induction. Anesthesia will be induced with rocuronium 1mg, propofol 3-6 mg/kg, and succinylcholine 1.5 mg/kg Depth of anesthesia will be measured with BIS-monitoring and a standard approaching 50% suppression will be maintained throughout the main duration of surgery. Reversal agent will be administered at a post-tetanic count of 1 or 2. Anesthesia will be maintained with Sevoflurane, Magnesium, Lidocaine, Ketamine, Decadron, Ondansetron, and Ketorolac at a concentration range/dose(s) based on the clinical need of the subject. Tracheal extubation will be performed at the end of anesthesia after administration of reversal agent. After extubation, the investigator will determine when the subject is OR discharge ready. |
Active Comparator: Opioid Anesthesia
Patients will receive intraoperative narcotics as part of their anesthesia regimen
|
Drug: Opioid Anesthesia
Doses/concentration of medications/agents used for the anesthetic management of the subjects enrolled in this trial may be adjusted when necessary to provide optimal subject care. Anesthesia will be induced with rocuronium, propofol, intravenous opioids, and other medication(s)/agent(s) at a concentration range/dose(s) based on the clinical need of the subject. Depth of anesthesia will be measured with BIS-monitoring and a standard approaching 50% suppression will be maintained throughout the main duration of surgery. Reversal agent will be administered at a post-tetanic count of 1 or 2. Anesthesia will be maintained with IV opioids, propofol and/or medication(s)/agent(s), including inhalation anesthetic agents, at a concentration range/dose(s) based on the clinical need of the subject. Tracheal extubation will be performed at the end of anesthesia after administration of reversal agent. After extubation, the investigator will determine when the subject is OR discharge ready. |
- Brief Pain Inventory [ Time Frame: Once a week for up to 12 months ]a standardized 9 question survey broken into pain severity and pain interference sections. The sections rank various items relating to their respective categorizations of pain on a scale from 0 to 10. The arithmetic mean of each section can then be utilized to determine Severity of pain and impact of pain on daily function during the past week.
- Post-surgical opioid prescription use, # of pills used per week [ Time Frame: Once a week for up to 12 months ]Weekly pill use for pain management upon discharge
- PACU: Pain Scores [ Time Frame: 1 - 3 hours ]Visual Analogue Scale (VAS) pain scores every 15 minutes on a 10 centimeter scale. Using a ruler, the score is determined by measuring the distance (cm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-10. A higher score indicates greater pain intensity. no pain (0 cm), mild pain(1-4.4 cm), moderate pain (4.5-7.4 cm), and severe pain (7.5-10 cm). Normative values are not available. The scale has to be shown to the patient otherwise it is an auditory scale not a visual one.
- PACU: Nausea Scores [ Time Frame: 1 - 3 hours ]Postoperative Nausea and Vomiting (PONV) every 15 minutes scores (0-4) 0, no nausea; 1, mild nausea ≤ 15 minutes; 2, nausea ≥ 10 minutes; 3, nausea ≥ 5 minutes; 4, vomiting
- PACU: Opioid Use in Morphine Equivalents [ Time Frame: 1 - 3 hours ]Total ammount of rescue narcotics used in PACU converted to milligram morphine equivalents using CDC guidelines for prescribing Opioids
- Patient Satisfaction [ Time Frame: 12 months ]Patient treatment satisfaction survey results
- Length of Stay [ Time Frame: 1- 5 days ]Total length of hospital stay in hours
