Investigation of the relationship between arterial blood gas analysis parameters and endoscopic findings in acute injuries of caustic ingestion in patients referred to the emergency department

Abstract

Burning consumption is a relatively rare effect with potentially life-threatening side effects. Swallowing caustic substances such as acidic, alkaline and the like is a common case that if not treated properly can cause dangerous side effects such as narrowing and possibly rupture of the gastrointestinal tract. The main purpose of this study was to investigate the relationship between arterial blood gas levels, including pH, HCO3 and PCO2, with the upper endoscopic grading scale according to the goldsmith classification. Materials and Methods: This was a retrospective cross-sectional study focusing on 52 patients with burn injuries who were referred to the emergency department of a third level hospital. The severity of endoscopic lesions was based on goldsmith classification. The patient was first resuscitated by the emergency medicine service upon arrival at the emergency room. Then arterial blood gas tests and analysis were performed. He then underwent endoscopy in coordination with the respected gastrointestinal tract and was hospitalized. He was discharged during treatment. We used 26 SPSS ver to analyze the data. Kendall Tau correlation was used to investigate the relationship between arterial blood gas levels and the degree of gastrointestinal damage. Results: The mean pH, HCO3 and PCO2 were not statistically significant between patients with low and high grade injuries. In addition, correlation with gastric injury was found to be weak. The only laboratory test that had a significant difference between the groups mentioned above was Hb.
