Study summary

After surgical tissue damage, cellular blood components are involved in tissue repair processes, yet their preoperative characteristics are not considered in routine clinical practice.

Read the detailed description

Surgical injuries initiate the recruitment of cellular blood components for tissue repair. Baseline inflammation levels and cellular response to tissue damage are absent from perioperative management algorithms despite their importance in regeneration. This project seeks to examine patients preoperative parameters before surgery and evaluate if there is a correlation with clinical outcomes.
