Features of patients with upper gastrointestinal bleeding and factors affecting the re-bleeding risk.

BACKGROUND: The risk of re-bleeding in upper gastrointestinal bleeding (UGIB) is a major complication that can be mortal. In this study, we aimed to determine the factors that can predict the risk of re-bleeding in UGIB patients. METHODS: We retrospectively screened UGIB patients admitted in adult intensive care. Along with age and gender, complaints of admission, vital signs, comorbidities, laboratory findings, medications, endoscopy status, and re-bleeding status were recorded. According to these findings, Glasgow-Blatchford and AIMS65 scores of the patients were calculated. All statistical tests were performed with the Predictive Analytics Software (PASW®, version 18, SPSS Inc., Chicago, IL). RESULTS: A total of 241 patients were included in the study. Mean age of patients was 57.58±19.31, years and 176 (73.0%) of them were male. A total of 117 (48.5%) patients were Helicobacter pylori positive and re-bleeding occurred in 77 (32.0%) patients. Sclerotherapy was applied in 103 (42.7%) patients, while 5 (2.1%) underwent electrocoagulation, and 4 (1.7%) underwent hemoclips. There was a significant difference between patients with and without endoscopic intervention for re-bleeding (p<0.001). Hematocrit, urea values, Glasgow-Blatchford, and AIMS65 scores were statistically significant different between the groups with and without re-bleeding (p=<0.001, <0.001, <0.001, and 0.008, respectively). In the ROC analysis of Glasgow-Blatchford and AIMS65 scoring systems area, under the curve values were 0.700 (p=<0.001, 95% CI: 0.626-0.775), and 0.557 (p=0.194, CI 95%: 0.469-0.645), respectively. Mortality rate was 2.1% (n=5) among study population. CONCLUSION: Hematocrit and urea values seem beneficial among studied laboratory values, however, Glasgow-Blatchford scoring system performed better than AIMS65 in the prediction of re-bleeding risk in UGIB. The authors concluded that more specific predictive markers may be useful for clinicians.

How reliable are electrolyte and metabolite results measured by a blood gas analyzer in the ED?

INTRODUCTION: Blood gas analysis is a frequently ordered test in emergency departments for many indications. It is a rapid technique that can analyze electrolyte and metabolites in addition to pH and blood gases. The aim of this study was to investigate the correlation of electrolyte and metabolite results measured by blood gas and core laboratory analyzers. METHODS: This was a prospective, single-center observational study conducted in a tertiary care center's emergency department. All adult patients requiring arterial/venous blood gas analysis and core laboratory tests together for any purpose were consecutively included in the study between April 2014 and July 2015. Patients younger than 16 years, having any intravenous infusion or blood transfusion prior to sampling, or who were pregnant were excluded. RESULTS: A total of 1094 patients' (male = 547, female = 547) paired blood samples were analyzed. The mean age was 58.10 ± 21.35 years, and there was no difference between arterial and venous sampling groups by age, pH, or sex (P = .93, .56, and .41, respectively). Correlation coefficients for hemoglobin, hematocrit, glucose, potassium, sodium, and chloride levels measured by blood gas analyzer and core laboratory analyzers were 0.922, 0.896, 0.964, 0.823, 0.854, and 0.791, respectively. CONCLUSION: Blood gas analysis results were strongly correlated for hemoglobin, hematocrit, glucose, potassium, and sodium levels but were only moderately correlated for chloride levels. These parameters as measured by a blood gas analyzer seem reliable in critical decision making but must be validated by core laboratory results.

A staged surgical treatment outcome of type 3 open tibial fractures.

Aim. In these case series which are about type 3 open tibial fractures formed with three different high energy trauma etiologies in different parts of tibia. We aimed to assess our three-stage treatment approach and discuss final results of our elective surgery management with three different fixation methods. Patients and Methods. We assessed 19 patients with type 3 open tibial fractures between 2009 and 2012. Our treatment protocol consisted of three stages. Early intervention in operating room, which including vascular repairs or soft tissue closure, was done if necessary. Definitive surgery was performed using internal or external fixation in the first 15 days. Patients were followed up for at least one year. Last conditions of all our cases were evaluated according to modified Johner and Wruhs criteria. Results. Nine cases were type 3A, seven cases were type 3B, and three cases were type 3C in terms of fracture typing. All patients were followed up for at least one year and mean follow up time was 15 months. In terms of functional and clinical outcome, six cases were evaluated as excellent, eight cases as good, two cases as fair, and three cases as poor. Discussion. Staged treatment option in type 3 open tibial fractures seems to be a good method in reducing complication and achieving the best result. We think that definitive staged treatment protocol including internal fixation with plating or intramedullary nailing (IMN) of the fractures is a reliable method, especially to avoid complications as a result of external fixator and to provide patient rapport.
