Comprehensive Study of Post-surgical Pain After Pectus or Spine Surgery

Study Purpose

This will be a prospective study to determine the association between specific genotypes, epigenetics, behavioral, social and biological factors, with the phenotypes, defined by pain perception, postoperative pain, analgesic effects, side effects to perioperative analgesics, chronic postoperative pain, and gene expression in patients following pectus excavatum repair.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

This study will be a clinical prospective study. It is observational for all aims except with regard to the Meditation Intervention, which will be limited to 100 pectus and 100 spine participants (randomized to 50/50 in each arm). We will recruit 600 qualifying participants over the study period to acquire the necessary data to derive a predictive model matching phenotype to genotype. This study will not interfere with the standard anesthetic or perioperative care except for blood sampling from an indwelling line, and the use of additional integrative health procedures (focused-attention meditation guidance, as well as routine massage and breathing techniques) for the randomized meditation group. Research staff will administer psychosocial and somatosensory assessments, as well as record relevant data from participant's medical records. Integrative health will assist in teaching focused-attention meditation to the randomized meditation participants in the preoperative phase. Actigraphy devices will be provided to all participants, and MUSETM to those in the randomized meditation group. The pain team, in accordance with the Pectus Pain Management Protocol, will direct perioperative pain management.

Arms & Interventions


No Intervention: Control

Participants in the control group will receive present standard of care, which includes an assessment of participant/family needs by integrative care after surgery, as well as standard holistic health care by a licensed/certified holistic health specialist. They will not receive the MUSETM focused-attention meditation training or intervention protocol.

Experimental: Meditation

Participants randomized to receive focused-attention meditation training will attend a preoperative training session, provided by a licensed/certified Holistic Health Specialist. The content will include an age appropriate explanation of focused-attention meditation, using breath as the focus; set-up and utilization of the MUSETM headband; and experiential practices. The goal of the intervention is to increase mindfulness (i.e., moment-to-moment, non-judgmental and non-reactive awareness of sensations, emotions, and thoughts), provide self-regulation strategies, and promote healthy and adaptive responses to stress.


Behavioral: - Meditation

Participants assigned to the Meditation intervention will receive focused attention meditation training preoperatively, and encouraged to meditate for 20 minutes per day before surgery. In the postoperative inpatient period, the participants will be offered standard holistic health care, reinforcement of meditation training, and encouragement to practice at least 20 minutes of guided focused-attention meditation with breath as their focus, utilizing the MUSETM headband for bio-feedback, every day during their hospital stay. They will be asked to continue using the MUSETM neurofeedback-assisted meditation after hospital discharge, until their visit to repeat pain testing, at which time they will return the MUSETM headband.
