Management of Hematemesis and Melena

Initial Assessment and Stabilization

The American College of Surgeons recommends assessing the extent of bleeding using established grading systems such as the Advanced Trauma Life Support (ATLS) classification, which evaluates blood loss based on vital signs, mental status, and clinical presentation 1
Secure large-bore intravenous access (ideally 8-Fr central access in adults) to allow for rapid fluid resuscitation, as recommended by the Anaesthesia journal 2, 1
Administer high FiO2 to ensure adequate oxygenation, as suggested by the Anaesthesia journal 2, 1
Insert a nasogastric tube to protect the airway, decompress the stomach, and assess ongoing bleeding, according to the World Journal of Emergency Surgery 3
Actively warm the patient and all transfused fluids to prevent hypothermia, which can worsen coagulopathy, as recommended by the Anaesthesia journal and Praxis Medical Insights 2, 1

Obtain baseline laboratory studies including complete blood count, prothrombin time (PT), activated partial thromboplastin time (aPTT), and Clauss fibrinogen, as suggested by the Anaesthesia journal and Praxis Medical Insights 2, 1
Do not rely on single hemoglobin/hematocrit measurements as isolated markers for bleeding, as they may not reflect acute blood loss, according to Praxis Medical Insights 1
Measure serum lactate and base deficit to estimate and monitor the extent of bleeding and shock, as recommended by Praxis Medical Insights 1
Consider near-patient testing such as thromboelastography (TEG) or thromboelastometry (ROTEM) if available, as suggested by the Anaesthesia journal and Praxis Medical Insights 2, 1

For massive hemorrhage, administer warmed blood and blood components, as recommended by the Anaesthesia journal 2
Transfuse packed red blood cells to maintain hemoglobin above 7 g/dL in most patients, according to the World Journal of Emergency Surgery 3
Consider a higher transfusion threshold of 9 g/dL in patients with massive bleeding, significant comorbidities (especially cardiovascular ischemia), or when therapeutic interventions may be delayed, as suggested by the World Journal of Emergency Surgery 3
In order of availability: O-type blood, group-specific blood, and cross-matched blood, as recommended by the Anaesthesia journal and Praxis Medical Insights 2, 1

Perform urgent endoscopic assessment in patients with acute bleeding (hematemesis or melena), as recommended by the Journal of the National Comprehensive Cancer Network 4
Implement appropriate endoscopic hemostatic interventions based on findings, according to the Journal of the National Comprehensive Cancer Network 4

Consider interventional radiology angiographic embolization techniques when endoscopy is not helpful or unsuccessful, as suggested by the Journal of the National Comprehensive Cancer Network 4
External-beam radiation therapy may be considered for chronic blood loss from gastric cancer, according to the Journal of the National Comprehensive Cancer Network 4
For massive, life-threatening lower gastrointestinal bleeding that is uncommon in patients with inflammatory bowel disease (occurring in less than 6% of cases), surgical intervention may be necessary, as recommended by the World Journal of Emergency Surgery 3

For patients with liver trauma presenting with hemobilia (bleeding from the ampulla of Vater) manifesting as melena or hematemesis, angioembolization is the treatment of choice, according to the World Journal of Emergency Surgery 5
In patients with inflammatory bowel disease, bleeding features differ between ulcerative colitis (diffuse mucosal ulceration) and Crohn's disease (focal erosion into an intestinal vessel), as suggested by the World Journal of Emergency Surgery 3
For patients on antiplatelet therapy who develop GI bleeding, careful consideration of thrombotic risk versus bleeding risk is essential, as recommended by the European Heart Journal 6, 7

Avoid delays between presentation and intervention for patients requiring urgent bleeding control, as recommended by Praxis Medical Insights 1
Do not rely solely on blood pressure as an indicator of blood loss, as some patients compensate well despite significant hemorrhage, according to the Anaesthesia journal and Praxis Medical Insights 2, 1
Avoid vasopressors once control of bleeding is achieved, as suggested by the Anaesthesia journal 2
Recognize that a single hemoglobin measurement may not reflect the true extent of blood loss in acute bleeding, according to Praxis Medical Insights 1

After initial stabilization, admit the patient to a critical care area for monitoring, as recommended by the Anaesthesia journal 2
Begin standard venous thromboprophylaxis as soon as bleeding is controlled, according to the Anaesthesia journal 2
Consider early CT angiography before colonoscopy in lower GI bleeding, as it may increase detection rates for vascular lesions (35.7% vs 20.6%), as suggested by the World Journal of Emergency Surgery 3
