NCT ID: NCT02322996 Withdrawn - Post op Pain Clinical Trials

Phenotyping Acute Pain for Discovery Research and Directed Therapeutics

Start date: February 21, 2018
Phase: N/A
Study type: Observational

The goal of the current study is to combine existing and new tools for quantifying patient self-report to characterize changes in acute pain. The ability to quantitatively measure self-report provides behavioral pain phenotypes that can serve as the basis for clustering patients into sub-groups based on their self-report of their symptoms, eliminating observer based perceptions of patients' pain.

NCT ID: NCT01939379 Withdrawn - Post-op Pain Clinical Trials

Adductor Canal Nerve Block Following Total Knee Arthroplasty

Start date: September 2013
Phase: N/A
Study type: Interventional

The purpose of this study is that an adductor canal nerve block (putting numbing medicine near the nerve) has been shown to produce excellent pain relief with less pain medication use after knee replacement surgery.The investigators will be comparing the amount of pain relief following knee replacement surgery when you have a nerve block in place. There will be approximately 66 subjects participating in this study. After surgery subjects will receive numbing medication every 6 hours for 48 hours. Subjects will also receive a morphine PCA (patient controlled analgesia) after surgery and pain medication by mouth every 4 hours around the clock with the option to receive more pain medication if needed. Subjects will participate in the study up to 3 days.
