Standardization of procalcitonin, C-reactive protein and lactate levels in pigs submitted to laparotomy / Padronização dos níveis de procalcitonina, proteína C- reativa e lactato em suínos submetidos à laparotomia

ABSTRACT

This study was undertaken to determine the procalcitonin, C-reactive protein and lactate levels in pigs anesthetized and submitted to laparotomy during 5 hours. A total of 05 landrace pigs with 3 months of age and weighing 26 kg were used. After a midline xiphopubic laparotomy, the procalcitonin, C-reactive protein (CRP) and lactate levels were measured at intervals of 60 minutes for 5 hours with samples taken from the jugular vein. The procalcitonin value remained below 0.05 µg. The CRP values were between 6.7 and 8.3 and lactate levels remained between 2.9 and 3.7 for the confidence interval of 95%. We conclude thtat in pigs submitted to laparotomy for 5 hours, the procalcitonin levels did not exceed 0.05 ng / mL. The C-reactive protein and lactate levels were between 6.7 and 8.3 mg / L and 2.9 and 3.7 mg / d, respectively. These data allowed reducing the number of animals.
