Brief summary:
Scoliosis is a disease that involves lateral and/or rotational deformity of the spine and can affect up to 4% of the population. Typically, surgery is considered when Cobb's angle, which is a measurement used for evaluation of curves in scoliosis on an anterior-posterior radiographic projection of the spine, is greater than 50 degrees in the thoracic region (40 degrees in the lumbar region) or when the curvature causes significant pain, or respiratory and cardiovascular restriction. Patient undergoing this surgical correction experience severe pain in the postoperative period and the management includes the use of opioid-based patient-controlled analgesia (PCA).

Scoliosis is a disease that involves lateral and/or rotational deformity of the spine and can affect up to 4% of the population.

Patient undergoing this surgical correction experience severe pain in the postoperative period and the management includes the use of opioid-based patient-controlled analgesia (PCA).

Methadone is an opioid with one of the longest elimination half-life and has been used as an effective analgesic for acute, chronic, neuropathic, and cancer pain in adults, children, and even neonates1-5. Its long duration of action and antagonism to the N-methyl-d-aspartate receptor may decrease the need for PCA use in the postoperative period. Gourlay2 demonstrated the effectiveness and utility of perioperative methadone including the advantages of longer analgesia with no serious side effects of respiratory depression. A recent study by Gottschalk2 in adult patients demonstrated a 50% reduction of postoperative opioids at 48 hours and lower pain scores after a single bolus of methadone before surgical incision. However, a major weakness of the study is that patients did not receive equipotent intraoperative opioids. In addition, the adolescent patient population will undergo a much larger surgical incision with potential for greater postoperative pain. Despite this potential benefit, methadone is seldom used in the perioperative setting. A more recent pharmacokinetic study of methadone in adolescents undergoing spine surgery failed to show a reduction in opioid consumption as it was powered to determine pharmacokinetics and not a secondary endpoint of postoperative opioid consumption. An appropriately powered study is still required to determine the efficacy of methadone in reducing postoperative pain after spine surgery.

Groups to be recruited will include:
     Patients
Which if any of the following vulnerable populations will be recruited as subjects?
     Children
Vulnerable populations require special protections.  How will you obtain informed consent, protect subject confidentiality, and
prevent undue coercion?
     
Patients presenting for spinal surgery will be identified from the Texas Children¿s Hospital operating room schedule that is
routinely available to pediatric anesthesiologists. This will be cross referenced with the pediatric orthopedic surgeons'
operative schedule as these cases are scheduled weeks to months in advance. The chart is reviewed to insure that the
patient qualifies based on the inclusion and exclusion criteria.
 
 
Potential subjects will be approached about participation on their visit to our preoperative screening clinic which occurs a
few days prior to surgery. The child will be approached with parental presence during the preoperative screening visit and
age appropriate language will be used to explain the study and answer any questions. Every opportunity will be given to
answering questions and discussing their options throughout the study. Enrollment in the study will only occur if the child
assents and the parent consent. Voluntary participation will be emphasized during recruitment of patients. A copy of the
IRB approved written consent form will be given to parents with time allowed for reading and considering enrollment.
Another opportunity to raise questions will be presented on the day of surgery in the holding area. All questions will be fully
answered and the child will then be asked to sign their name on the assent portion with parent or guardian signing the IRB
approved consent. A translator will be available for Spanish speakers and a fully translated consent form approved by the
IRB will be used for these subjects. (A Spanish consent will be submitted as an amendment after the English consent is
approved. No Spanish speakers will be recruited for enrollment prior to IRB approval of a Spanish translation of the
consent form.) Participants will be assured that every effort will be made to protect privacy and to prevent a breach of
confidentiality.

This patient and observer blinded prospective randomized study will be performed on patients (aged 10 - 17years, both
males and females, from all ethnic backgrounds) undergoing multilevel thoraco-lumbar spine surgery with instrumentation
and fusion at Texas Children¿s Hospital, Houston, TX. After obtaining IRB (Institutional Review Board) approval and
written informed consent from each patient or his or her legal representative, 56 patients scheduled for multilevel thoraco-
lumbar spine surgery with instrumentation and fusion will randomly be assigned into two groups (control or treatment
group) based on a computer generated random number using Random Allocation Software For Parallel Group
Randomized Trials. There is an equal chance of being assigned to either group. The control group will be given placebo;
whereas the treatment group will receive methadone 0.2 mg/kg intravenously.

F2.  Procedure
     
The perioperative management of patients will be in keeping with the current standard practices at Texas Children¿s
Hospital. Before surgery, patients will be asked to rate their baseline pain using a verbal rating scale from 1 to 10 by a
member of the research team. In addition, information on preoperative opioid consumption during the last 30 days will be
collected. 
 
Muscle spasms after scoliosis surgery are a common cause of postoperative pain. Our current practice is to provide oral or
IV diazepam to treat muscle spasms. Many patients who undergo scoliosis repair receive pre-operatively oral diazepam or
midazolam for anxiolysis. In order to prevent introducing a confounding factor in the evaluation of postoperative pain
scores in the recovery period, the protocol will require all patients to receive the same preoperative medication (oral
diazepam). After intravenous access, endotracheal intubation will be facilitated with additional bolus of propofol 1-3 mg/kg
or succinylcholine 1-2 mg/kg at the discretion of the intra-operative anesthesiologist. According to the randomization plan,
after intubation, the control group will receive a 20 ml normal saline placebo infusion over 10 minutes, while the treatment
group will receive 0.2 mg/kg methadone diluted to a 20 ml infusion over 10 minutes. The inhalational agent will be turned
off at intubation in keeping with standard TCH practices. Total intravenous anesthesia in both groups will be maintained in
keeping with standard TCH practices for neuromonitoring (somatosensory evoked potentials (SSEPs) and motor evoked
potentials (MEPs) with propofol 75 - 200 mcg/kg/min and sufentanil 0.2 ¿ 0.5 mcg/kg/hour, adjusting the doses to achieve
a targeted bispectral index level of 40-60. Nicardipine infusion may be used for controlled hypotension at the discretion of
the intra-operative anesthesiologist. The sufentanil and propofol infusion will be turned off when the second rod is placed
and after the final SSEPs, MEPs are obtained. Anesthesia will be maintained with inhalational agent until the end of the
surgical procedure. At the end of surgical procedure, residual neuromuscular blockade will be antagonized and the trachea
extubated in the operating room when the Anesthesiologist decides it is safe. The patient will then be transferred to the
post anesthesia recovery room (PACU). Both the intra-operative anesthesiologist and the researcher staff gathering the
PACU pain scores and use of PCA will be blinded to the medication. 
 
Postoperative Analgesia All groups: In keeping with current practice, supplemental oxygen will be available for oxygen
saturations less than 94% during spontaneous ventilation. All patients will be monitored with continuous pulse oximetry as
in keeping with practice at TCH. Every patient will have a patient controlled analgesia (PCA) morphine pump with a basal
rate infusion of 0.01 mg/kg/hour, a demand dose 0.02 mg/kg with a lockout time of 10 minutes to be started in the PACU
once the patient emerges from the anesthetic. The patient will be administered diazepam 0.05 mg/kg IV or oral with
maximum of 5 mg every 6 hours as needed for muscle spasms in keeping with current practice. On POD 1, the basal rate
of morphine will be discontinued and ketorolac 0.5 mg/kg every 6 hours initiated in keeping with current practices. On POD
3, the patient will be transitioned from the PCA with scheduled oral hydrocodone/acetaminophen at a dosage of 0.135
mg/kg of hydrocodone with a maximum of 15 mg every 4 hours in keeping with current practice. The PCA will be available
for use during the transition for breakthrough pain. 
 
Postoperatively, patients will be asked to rate their pain using a validated pain scale (a verbal rating scale where 0 = no
pain and 10 = worse pain ever) by a blinded research staff member. These pain scores will be collected at 1 hour after
entry into recovery and every 4 hours during the first five days of hospitalization both at rest and during activity by the
nurses. The cumulative intravenous opioid requirement at 24, 48, and 72 hour will be recorded. The cumulative
breakthrough intravenous opioid requirement after initiation of oral pain medication will also be collected. The level of
sedation will be determined using the University of Michigan Sedation Scale. In addition, complications such as the
incidence of hypotension (defined as mean arterial blood pressure less than 50 mm Hg), the need for vasopressors, the
incidence of respiratory depression (defined as a respiratory rate less than 8 breaths per minute, respiratory arrest, or the
need for naloxone), the incidence of hypoxemia or desaturation (defined as oxygen saturation [Sao2] less than 90% or the
need for a supplemental oxygen to maintain Sao2 greater than 94%), the incidence of cardiac arrhythmias, and the
incidence of nausea and vomiting including the treatment of side effects will be also recorded. Upon discharge from the
hospital, the patients will be asked to keep a diary consisting of daily opioid usage, episodes of nausea and vomiting, daily
activity level, and satisfation scores. As part of standard routine post-surgical followup in the orthopedic clinic, information
is collected from the patients which consist of questionnaires regarding pain scores, functional status, activity level, and
quality of life. The research team will collect this information at 3 months and 6 months postoperatively.
 
Section G:  Sample Size/Data Analysis
G1.  Sample Size
How many subjects (or specimens, or charts) will be used in this study?


12/28/2020
Human Protocol Report
https://brain.bcm.edu/esp1/reports/Human/Protocol.asp?protocol=403715
6/10
     Local: 98              Worldwide: 98
Please indicate why you chose the sample size proposed:
     
The sample size was based on the assumption that opioid use in the first 3 days in the placebo group would be similar to
that in a previously published study of the same patient population undergoing spine surgery (mean 275 mg SD 75 mg). A
group size of 28 would be required for an 80% power of detecting a 30% reduction in opioid use from 275 to 200 mg at the
0.05 level of significance. Allowing for a 50% dropout rate for incomplete data, we will recruit 49 patients in each group for
a total of 98 subjects.
G2.  Data Analysis
Provide a description of your plan for data analysis. State the types of comparisons you plan (e.g. comparison of means,
comparison of proportions, regressions, analysis of variance). Which is the PRIMARY comparison/analysis? How will the
analyses proposed relate to the primary purposes of your study?
     
The primary endpoint of the study is the morphine consumption during the first 72 postoperative hours. The secondary
outcomes include pain scores and the incidence of side effects such as respiratory depression, nausea, and vomiting.
Continuous data including pain scores will be first examined for a normal distribution by the Shapiro ¿ Wilk test. The
outcome variables between the two groups will be compared with Student¿s t-test where appropriate, for normally
distributed continuous data or by nonparametric tests if the data were not normally distributed. It is anticipated that the
distribution of pain scores will not be normal and that non-parametric tests will be required. Categorical data including
patient gender, ASA physical status, incidence of side effects (respiratory depression, need for oxygen beyond the first 2
hours, nausea and vomiting) will be compared by Fisher¿s exact test Analysis of variance for repeated measures will be
performed to compare differences in pain scores between the treatment groups with time. Data will be presented as mean,
standard deviation, median values or numbers (percentages). P values less than 0.05 will be considered statistically
significant. In order to maintain a robust statistical analysis, we will also examine the differences in subjects with and
without completely evaluable data in known factors that affect postoperative pain after spine surgery (e.g., age, gender,
ASA physical status, duration of surgery, intraoperative opioids medications, time of the PACU stay, mean and peak pain
scores and recorded opioid consumption in the PACU before discharge). Failure to show a difference in these factors may
suggest that the missing data can be considered to be missing at random.
 
Section H:  Potential Risks/Discomforts
H1.  Potential Risks/Discomforts
Describe and assess any potential risks/discomforts; (physical, psychological, social, legal, or other) and assess the likelihood
and seriousness of such risks:
     
In this study, we are comparing the addition of another opioid pain medication to reduce pain scores and overall total
hospital opioid consumption. Current standard practices for patients undergoing multi-level spine surgery will be used with
the exception of methadone given to the treatment group. Methadone may induce prolongation of the rate-corrected QT
interval (QTc); however, patients with cardiac arrhythmias or congenital heart disease will be excluded from the study. Side
effects of respiratory depression from methadone should not be greater than with typical morphine usage. 
 
Additional risks of the study are the small chance of loss of privacy. The data will be coded. No data identifying the patient
will be extracted from the medical records and all data will be kept locked in the offices of the Principal Investigator. Any
electronic version will be kept in a password protected network servers controlled by the IT services at the TCH.
Computers with access to this network are kept in a locked office where entry is limited to those with an ID key card. This
office is located inside the office of the Department of Anesthesiology at Texas Children's Hospital. Unauthorized
individuals would not be able to enter these facilities. The likelihood of such events is minimal.
H2.  Data and safety monitoring plan
     Do the study activities impart greater than minimal risk to subjects?
     
     Yes

Section I:  Potential Benefits
Describe potential benefit(s) to be gained by the individual subject as a result of participating in the planned work.

Human Protocol Report
https://brain.bcm.edu/esp1/reports/Human/Protocol.asp?protocol=403715
7/10
     Patients assigned to the methadone group may have reduced postoperative pain scores and a reduction of total
consumption of postoperative opioids. Patients with less opioid use may benefit from fewer side effects. However, it is
possible that there will be no benefits from participating in the study.
Describe potential benefit(s) to society of the planned work.
     
Data from this study can be used to determine if methadone provides better pain control in the perioperative setting.
Knowledge obtained from this study may allow anesthesiologists from other institutions caring for children and adolescents
undergoing similar painful procedures to use this medication to reduce pain.
Do anticipated benefits outweigh potential risks? Discuss the risk-to-benefit ratio.
     
The risks in this study do not vary from the risks of standard practices at TCH for children undergoing multi-level thoraco-
lumbar spinal instrumentation and fusion. The additional minor risk of an unlikely loss of privacy is outweighed by the
societal benefits from this knowledge.
