Registration Number: NCT01848158

Lead Sponsor: Seattle Children's Hospital

Brief Summary: The purpose of this study is to determine whether acupuncture is effective at improving comfort in children on a ventilator in the intensive care unit. Our hypothesis is that the patients receiving acupuncture will require less medications to keep them comfortable than those who receive sham or fake acupuncture.

Detailed Description: Rationale: Use of narcotics and benzodiazepines is common in the pediatric intensive care unit (PICU) to alleviate pain and anxiety, especially for patients who are mechanically ventilated. Pain control and sedation decrease oxygen consumption, facilitate mechanical ventilation, ensure patient safety and help patients tolerate nursing care. However, these medications can also have negative consequences. Patients receiving greater amounts of pharmacologic sedation in the intensive care unit (ICU) have longer duration of mechanical ventilation and ICU length of stay. In fact, daily interruption of sedation shortens duration of mechanical ventilation and ICU length of stay. Sedatives have also been associated with development of delirium in ICU patients and linked to delusional and disturbing memories and post-traumatic stress disorder (PTSD) after recovery from critical illness. Benzodiazepines and opiates are associated with abnormal sleep architecture. Furthermore, patients experience tolerance, physical dependency and withdrawal from these agents. Lastly, there is evidence that sedatives, anesthetics and opiates are associated with neurotoxicity in animal studies leading to growing concern about the potential effects of these agents on the developing brains of children.

Novel Approach: In light of these negative aspects of pharmacologic sedation, we are looking for alternative ways to provide comfort to critically ill children in the PICU. Acupuncture has been found to be effective in reducing anxiety, acute pain, procedural pain, post-operative pain, chronic pain, headache, infant colic, and has been found to reduce anesthetic requirement during surgery.

Study Plan: We plan to randomize patients 6 months - 17 yrs old who are receiving mechanical ventilation in the PICU to either acupuncture or sham acupuncture as an adjunct to standard of care pharmacologic sedation as prescribed by the PICU medical team caring for the patients. Our hypothesis is that those patients receiving acupuncture will require less medications to keep them comfortable. Our study is powered (80%) to detect a 33% decrease in pharmacologic sedation/analgesia.

Arm && Interventions

Group	Intervention	Description
Acupuncture	acupuncture	Acupuncture treatment three times per week for up to two weeks.
Sham Acupuncture	sham acupuncture	Sham acupuncture three times per week for up to two weeks

Primary Outcome Measures

Name	Time	Method
Average Daily Morphine Equivalents (mg/kg/Day)	from time of first acupuncture/sham treatment till time of extubation	Measured total amount of morphine equivalent received from time of first acupuncture or sham treatment to extubation, normalized per weight and time on study (1st study treatment to extubation).
Average Daily Dexmedetomidine mcg/kg/Day	from time of first acupuncture/sham treatment till time of extubation	Measured total amount of dexmedetomidine received from time of first acupuncture or sham treatment to extubation, normalized per weight and time on study (1st study treatment to extubation).
Average Daily Midazolam Equivalents (mg/kg/Day)	from time of first acupuncture/sham treatment till time of extubation	Measured total amount of midazolam equivalent received from time of first acupuncture or sham treatment to extubation, normalized per weight and time on study (1st study treatment to extubation).
Average Daily Sedation Score	from time of first acupuncture/sham treatment till time of extubation	To capture a global view of sedation and account for the combination of medications received, we also calculated an average daily 'sedation score' normalized for weight from the time of first treatment through extubation. The sedation score is a summary measure of sedative and analgesic exposure for mechanically ventilated children in the ICU. This score incorporates opioids, benzodiazepines, barbiturates, chloral hydrate, propofol, and antihistamines. Morphine and midazolam equivalents of 0.1 mg/kg, pentobarbital 2 mg/kg, chloral hydrate 50 mg/kg, any propofol use, and any phenobarbitol use are each allocated one point, while any antihistamine use receives a score of 0.5 (Randolph 2002, Curley 2005). We modified this score to include dexmedetomidine, assigning 1 point for 1 μg/kg of dexmedetomidine. The minimum value possible is zero, and there is no pre-defined maximum value. A higher score indicates higher dose of sedation medications (normalized by weight).
