Abstract
BackgroundThere is a well known relationship between hypoperfusion and postoperative complications like anastomotic leak. No studies have been done addressing this relationship in the context of abdominal trauma surgery. Central venous oxygen saturation is an important hypoperfusion marker of potential use in abdominal trauma surgery for identifying the risk of anastomotic leak development. The purpose of this study was to identify the relationship between low values of central venous oxygen saturation and anastomotic leak of gastrointestinal sutures in the postoperative period in abdominal trauma surgery.MethodsA cross-sectional prospective study was performed. Patients over 14 years old who required surgical gastrointestinal repair secondary to abdominal trauma were included. Anastomotic leak diagnosis was confirmed through clinical manifestations and diagnostic images or secondary surgery when needed. Central venous oxygen blood saturation was measured at the beginning of surgery through a central catheter. Demographic data, trauma mechanism, anatomic site of trauma, hemoglobin levels, abdominal trauma index, and comorbidities were assessed as secondary variables.ResultsPatients who developed anastomotic leak showed lower mean central venous oxygen saturation levels (60.0% ± 2.94%) than those who did not (69.89% ± 7.21%) (p = 0.010).ConclusionsCentral venous oxygen saturation <65% was associated with the development of gastrointestinal leak during postoperative time of patients who underwent surgery secondary to abdominal trauma.
Highlights
There is a well known relationship between hypoperfusion and postoperative complications like anastomotic leak
Tissue hypoperfusion results from circulatory disturbances during hypoxic and hemorrhagic periods, and evidence suggests that Central venous oxygen saturation (ScvO2) reflects the early stages of hypoperfusion [6, 11,12,13,14,15]
The main purpose of this study was to explore possible associations between tissue hypoperfusion identified through ScvO2 measurement and the development of anastomotic leak during the postoperative period of abdominal trauma patients
Summary
There is a well known relationship between hypoperfusion and postoperative complications like anastomotic leak. No studies have been done addressing this relationship in the context of abdominal trauma surgery. Central venous oxygen saturation is an important hypoperfusion marker of potential use in abdominal trauma surgery for identifying the risk of anastomotic leak development. The purpose of this study was to identify the relationship between low values of central venous oxygen saturation and anastomotic leak of gastrointestinal sutures in the postoperative period in abdominal trauma surgery. Other hypoperfusion marker is lactic acid, which is elevated during low tissue oxygenation even under normal vital signs. The main purpose of this study was to explore possible associations between tissue hypoperfusion identified through ScvO2 measurement and the development of anastomotic leak during the postoperative period of abdominal trauma patients. Our hypothesis is that low measurements (
