Sepsis Abdominal

This single-center, prospective, observational study evaluates the impact of perioperative sepsis on inflammatory response, coagulation abnormalities, cardiac dysfunction, and microRNA expression in adult patients undergoing major abdominal surgery. Forty patients are enrolled and classified into septic and non-septic groups according to international sepsis definitions based on SOFA score criteria. Clinical, biochemical, echocardiographic, and molecular parameters, including selected microRNAs, are assessed preoperatively and within the first 24 hours postoperatively. The study aims to characterize pathophysiological differences associated with perioperative sepsis and to explore the potential prognostic value of microRNAs as early biomarkers of postoperative sepsis.

The goal of this clinical trial is to compare the clinical effects of using Ringer's Lactate and Sterofundin/ Plasmalyte as maintenance fluids in adult patients who have undergone abdominal surgery and are septic. The primary outcome will be the change in serum lactate levels. Secondary outcomes will include renal function parameters, qSOFA scores, and the incidence of postoperative complications within the first 72 hours following surgery.

This study is a single-center, randomized, double-blind, placebo-controlled trial.

To early evaluate the serum levels of calprotectin in patients suffering from intra-abdominal sepsis requiring a surgical treatment. The research project aims to investigate the role of serum calprotectin in the diagnosis of sepsis and to establish whether its level significantly correlates with different degree of disease severity and with short and long-term outcomes. If these associations were confirmed, serum calprotectin would represent an easily and rapidly detectable biomarker able to predict the severity of sepsis.
