Study summary

The purpose of this study is to determine if auricular acupuncture significantly reduces post-operative pain in comparison to the standard of care. Post-operative pain score will be collected by subject self-report of pain according to the Numerical Rating Scale (NRS) (0= no pain, 10 = worst imaginable pain) up to 10 days post-operation.

DESIGN:

Design type: Prospective, randomized control trial Sample

  • Description of the population: All adults, greater than or equal to 18 years, undergoing a tonsillectomy with or without adenoidectomy at Womack Army Medical Center are eligible for participation in the study.
  • Sample Size: 100 subjects. A target of 45 subjects per group for a total of 90 subjects, and accounting for a 10 percent drop out rate. In Fiscal Year 12, 92 tonsilectomies in patients over the age of 12 were performed at Womack Army Medical Center. Therefore, the investigators anticipate the study will take up to 4 years to enroll 100 adult subjects.
  • Power Analysis: Under the assumption of a linear time by treatment interaction, assuming subject-level randomization, five time-points, power of 80 percent, a Type I error rate of 5 per cent and no attrition, to detect a 1.6 difference in pain score requires a total sample size of 90 subjects or 45 per treatment arm.

Study arms

  • Experimental
    Group 1 - Receives auricular acupuncture

    Receives "Battlefield Acupuncture" (BFA) as soon a anesthesia is initiated and needles removed right before they are extubated and awakened.

    Other: Auricular acupuncture

  • No intervention
    Group 2 don't receive anything

    They do not receive any any acupuncture only standard of care.

Interventions

  • OtherAuricular acupuncture

    The ear will be cleaned with alcohol prior to insertion of the needles. Five sterile, single-use, gold needles will be placed in each ear according to the figure below. The needles penetrate about a millimeter (or 4/100ths of an inch) into the skin.

What researchers measure

Primary outcomes

  1. Pain Scores

    Pain scores will be collected daily during the post op period in the recovery room using a numbers scale with faces; specifically the Wong-Baker FACES® Pain Rating Scale where 10 is described as worst possible and 0 is No pain. This was recorded by the participant at home using the same type scale and this was is provided to them. The Hypothesis is that subjects receiving intraoperative auricular acupuncture during a tonsillectomy will have statistically significantly less post-operative pain scores compared to those that do not.

    Time frame: 10 days after the procedure.

  2. The Morphine Equivalent of Opioid Use

    The intraoperative and recovery room morphine equivalents will be calculated and upon diary return what use is recorded by the patient will be done as well. The participant is instructed to write down the type and amount they take throughout that time period.

    Time frame: Intraoperative to 10 days post operative utilizing the Johns Hopkins Opioid conversion system.

Secondary outcomes

  1. Return to Diet

    Subjects will record on their diary the date they returned to a regular diet (defined to them what is regular for them)

    Time frame: Within 10 days post operatively

  2. Number of Participants With Nausea Post Operatively

    It will be documented yes or no if the participant voiced any complaint of nausea while in recovery.

    Time frame: 1-3 hours postoperativey

  3. Number of Participants With Nausea Post Operatively

    It will be documented yes or no if the participant had any emesis while in recovery prior to discharge home.

    Time frame: 1-3 hours post operatively
