NCT01495611

Brief Summary

The purpose of this research study is to identify factors and genes (the DNA material that determines the makeup of the human body) that may be associated with how children respond to pain medication. Specifically, the investigators want to study factors that may be associated with pain sensitivity, morphine requirement after surgery and side-effects from morphine and other pain medications. The investigators expect that the information obtained in this research study will help us to develop more effective, safe, and tailored treatment options in the future.

Biospecimen

Retention: SAMPLES WITH DNA

A database/ repository will be constructed for future research, analysis, and recruitment. De-identified study subjects' genetic information and their responses to pain and pain medications, side-effects will be included in the database. Blood specimens will be included in the repository for exploring potentially important SNPs and biomarkers in future. No patient identifiers will be included in the repository and there will be a confidential (access limited to investigators only) code or link between the repository/database and other information about the participant.
