Anesthetic Optimization in Scoliosis Surgery (AIS)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02481570
Recruitment Status : Completed
First Posted : June 25, 2015

University of Florida

Brief Summary:
The standard anesthetic care plan for people having adolescent idiopathic scoliosis surgery will be accompanied by a pharmacokinetic simulation of the administered drugs to suggest opportunities to adjust drug doses to achieve tolerable pain control after surgery, avoid respiratory depression and allow patients to respond quickly either during intraoperative testing or at the conclusion of surgery.

Condition or disease Intervention/treatment Phase
Adolescent Idiopathic Scoliosis Respiratory Depression Postoperative Pain Other: pharmacokinetic simulation Not Applicable

Detailed Description:
As part of this study, anesthesiologists will be given additional data on the expected drug effects based on a computer simulation. The data will be provided as a suggestion and will be used together with all the other information normally used to keep the study subjects safely asleep during surgery. In addition, data will be collected from the medical history and on postoperative pain control and medication side effects for the first 24 hours. Specifically, study subjects will be asked to rate their pain on a 10-point scale after they wake up from surgery and once they arrive in the pediatric intensive care unit. Measures of the time from the end of surgery until the study subjects are awake and out of the operating room will also be collected.

Arm Intervention/treatment
Experimental: Anesthesia optimization
Information from the pharmacokinetic simulation during an anesthetic regimen of a propofol based Total Intravenous Anesthetic (TIVA)
Other: pharmacokinetic simulation
The aim of the simulation is to recommend dosing adjustments to improve postoperative analgesia with a rapid emergence.

Primary Outcome Measures :
  1. 4-Item Pain Intensity Measure [ Time Frame: 24 hours ]
    0 - 10 (0=no pain; 10 = pain as bad as can be)

  2. Respiratory depression [ Time Frame: 24 hours ]
    Respiratory rate less than 10 breaths per minute (bpm), or administration of naloxone.

Secondary Outcome Measures :
  1. Utility of pharmacokinetic simulation [ Time Frame: 4 - 8 hours (Intraoperative period) ]
    The number of modifications to the anesthetic dosing
