Information provided by (Responsible Party):
Dhanesh Gupta, Northwestern University
  Purpose
What is the influence of methadone on postoperative analgesia after lumbar interbody fusion in opioid naïve patients or patients who are taking less than equivalent of 15 mg IV morphine each day? What is the incidence of opioid related postoperative side effects after the administration of methadone in the operating room?

Condition Intervention
Postoperative Pain Drug: Methadone Drug: Saline

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)

Primary Outcome Measures:
  • Hydromorphone postoperative opioid consumption (POC) at 48 hours [ Time Frame: 48 hrs ]
    PCA opioid consumption during the initial postoperative 48 hours after arriving in the PACU


Secondary Outcome Measures:
  • Intraoperative remifentanil consumption [ Time Frame: the 8 hours prior to arrival in the recovery room ]
    intraoperative consumption of remifentanil--the amount of remifentanil used in the OR (i.e., the 2-8 hours prior to arrival in the recovery room)

  • pain at rest and with movement (numerical Rating Scale, NRS) [ Time Frame: 1 hr, 6 hrs, 12 hrs, 24 hrs, 36 hrs, 48 hrs ]
  • the level of sedation (modified Observer's Assessment of Alertness and Sedation Scale, modified OAA/S scale) [ Time Frame: 1 hr, 6 hrs, 12 hrs, 24 hrs, 36 hrs, 48 hrs ]
  • the number of occurrences of ventilatory depression during each evaluation interval [ Time Frame: 1 hr, 6 hrs, 12 hrs, 24 hrs, 36 hrs, 48 hrs ]
  • number of occurrences of nausea (resulting in treatment) [ Time Frame: 1 hr, 6 hrs, 12 hrs, 24 hrs, 36 hrs, 48 hrs ]
  • recorded emesis [ Time Frame: 1 hr, 6 hrs, 12 hrs, 24 hrs, 36 hrs, 48 hrs ]
  • occurrence of pruritus [ Time Frame: 1 hr, 6 hrs, 12 hrs, 24 hrs, 36 hrs, 48 hrs ]
  • Hydromorphone postoperative opioid consumption (POC) [ Time Frame: 1 hr, 6 hrs, 12 hrs, 24 hrs, 36 hrs ]
    PCA opioid consumption at postoperative 1 hr, 6 hrs, 12 hrs, 24 hrs, 36 hrs after arriving in the PACU

Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Methadone Group
0.2 mg/kg IV methadone
Drug: Methadone
0.2 mg/kg methadone IV bolus
Other Name: Dolophine
Placebo Comparator: Placebo Group
5 mL saline bolus
Drug: Saline
3 mL saline IV bolus
Other Name: 0.9 NaCl

Detailed Description:

Hypothesis:

  1. We hypothesize that 0.2 mg/kg of methadone will result in decreased postoperative hydromorphone consumption compared to hydromorphone alone in opioid naïve patients or patients who are taking less than the equivalent of 15 mg IV morphine a day undergoing lumbar interbody fusion.
  2. We hypothesize that the incidence of opioid related postoperative side effects will not be increased by the administration of methadone in the operating room.
