Determining the site and severity of blood loss is important in the management of children with gastrointestinal (GI) bleeding. Blood urea nitrogen (BUN) and serum creatinine (Cr) were measured on the day of hospitalization and the ratio of BUN/Cr was calculated in 11 children with 16 episodes of upper GI bleeding and 49 with lower GI bleeding. There was a significant difference between the two GI bleeding groups with regard to BUN/ Cr ratio (p ≥ 0.001). When the ratio was 30 or above, the… 

Availability of Blood Urea Nitrogen/Creatinine Ratio in Gastrointestinal Bleeding with Melena in Children

TLDR
The BUN/Cr ratio was not uneven in differentiating UGIB from LGIB of children with melena in this study, which suggests that BUN-Cr ratio should be interpreted carefully.

Blood Urea Nitrogen to Creatinine ratio in Differentiation of Upper and Lower Gastrointestinal Bleedings; a Diagnostic Accuracy Study

TLDR
Considering the relatively proper specificity and positive predictive value of BUN/Cr ratio, values higher than 35 can predict upper GI bleeding with high probability, in cases that bleeding source cannot be determined using other non-invasive methods.

Association of gastrointestinal hemorrhage with increased blood urea nitrogen and BUN/creatinine ratio in dogs: a literature review and retrospective study.

TLDR
The increase in BUN/creatinine ratio suggested that the increased BUN concentration in dogs with evidence for UGH primarily was associated with increased gastrointestinal absorption of nitrogenous compounds, and hepatic ureagenesis.

Diagnostic evaluation of urea nitrogen/creatinine ratio in dogs with gastrointestinal bleeding

TLDR
The UCR does not seem to be a clinically useful marker of occult GIB and appears to have poor discriminatory ability between upper and lower GIB.

Does blood urea nitrogen level predict severity and high-risk endoscopic lesions in patients with nonvariceal upper gastrointestinal bleeding?

TLDR
In patients with nonvariceal UG IB, the BUN level at initial presentation is a weak predictor of the severity of UGIB as defined by ICU admission, but is not helpful in identifying patients with a HRL.

How to Differentiate Sites of Gastrointestinal Bleeding in Patients with Hematochezia by Using Clinical Factors?

TLDR
Three clinical factors were significantly associated with UGIB causes in patients with hematochezia including systolic blood pressure, hematocrit level, and BUN/Cr ratio and Physicians at the ED could use these clinical factors as a guide for further investigation in patients who presented with he matchezia.

Upper Gastrointestinal Bleeding

TLDR
The goals of therapy in a child with GI bleeding should involve hemodynamic resuscitation, cessation of bleeding from source and prevention of future episodes of GI bleeding, as well as investigating the source, degree and possible cause of the bleeding.

Diagnosis and Management of Upper Gastrointestinal Bleeding in Children

TLDR
The clinician needs to determine carefully whether any blood or possible blood reported by a child or adult represents true upper gastrointestinal bleeding because most children with true upperintestinal bleeding require admission to a pediatric intensive care unit.

Blood Urea Nitrogen Levels to Verify Estimated Glomerular Filtration Rate, as Derived from 2 Commonly Used Equations.

TLDR
A BCR of 20 or greater caused misestimation of the CKD stage and GFR estimates for patients with high BCR should be interpreted cautiously.
