Brief Summary

Procalcitonin (PCT) is a reliable biomarker of infection and sepsis. The investigators aimed to determine whether tracheotomy influences PCT concentrations in patients without sepsis, and to assess whether operative duration and procedure affect the peak PCT level.

Detailed Description

Procalcitonin (PCT), a soluble protein composed of 116 amino acids with a sequence identical to that of the calcitonin prohormone, has been considered as a reliable biomarker for evaluating of bacterial infection and sepsis. In healthy individuals, serum PCT concentrations are undetectable, however, in case of severe bacterial infections and sepsis, it increase rapidly released mainly in peripheral blood mononuclear cells and modulated by bacterial lipopolysaccharides (LPS) and sepsis-associated cytokines. An increase number of studies have demonstrated that PCT-guided strategy is a helpful approach to guide antibiotic administrations and clinical interventions in the intensive care unit (ICU).

However, PCT is induced in the plasmas of patients not only at the presence of bacterial infection, but also in stress conditions such as severe trauma and surgery. In these conditions, the increases are moderate. The mechanism of the nonspecific increase is complicated. Other conditions with elevated PCT concentrations include medullary thyroid carcinoma , cancer, anaphylactic shock, heat shock , cardiac arrest, Kawasaki Disease, and so on. These findings suggest that elevated PCT levels lack the speciality to detect sepsis in critically ill patients.

Tracheotomy is one of most performed surgical procedures to assure airway by making a hole in front of the trachea in ICU. There are studies in literature that show the surgical procedures to the neck area cause a surgical stress, an increase in thyroid hormones. The procedure may due to miscellaneous clinical signs by altering in hormone levels, even creating a thyroid storm. As far as we are aware, there is no study on the impact of tracheotomy on PCT concentration. The aim of the study was to evaluated whether tracheotomy affects PCT concentrations in patients without sepsis. Moreover, the investigators assessed whether operative duration and procedure were correlation with the peak PCT level.
