Optimization of Time-of-Flight Mass Cytometry (CyTOF) Analysis for Evaluation of Immune Changes Following Surgery

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01882569
Recruitment Status : Completed
First Posted : June 20, 2013

Brief Summary:
Surgical trauma triggers a massive inflammatory response. Over time, both the innate and adaptive branches of the immune system are affected by surgical trauma. The purpose of this study is to use a single cell flow cytometry approach to characterize the cellular and molecular mechanisms involved in the inflammatory response to surgical trauma.

Back surgery

Primary Outcome Measures :
  1. Numerical (cell frequencies) and functional (phosphorylation of signaling proteins and transcription factors) changes of all circulating immune cells [ Time Frame: Immediately before to surgery, 1 hour after surgery, 24 hours after surgery, and day of hospital discharge ]
    This is an exploratory study.
