Symptoms and Signs – Differential Diagnosis of Hematemesis
Hematemesis, the act of vomiting blood, often denotes gastrointestinal bleeding occurring above the ligament of Treitz, which serves to suspend the duodenum at its point of connection with the jejunum. Fresh or recent bleeding is indicated by bright crimson or blood-streaked vomitus. Emesis of dark red, brown, or black hue (resembling the color and texture of coffee grounds) suggests the presence of blood that has been retained in the stomach and has undergone partial digestion.
Typically caused by a gastrointestinal illness, hematemesis can also arise from a coagulation disorder or a therapy that causes irritation to the gastrointestinal tract. Gastroesophageal varices Possible cause of hematemesis. The ingestion of blood from epistaxis or oropharyngeal erosion can also result in the occurrence of bloody vomitus. Acute hematemesis can be triggered by physical exertion, psychological pressure, and the consumption of an anti-inflammatory medication or alcohol. Hematemesis in a patient with esophageal varices might occur due to trauma caused by an ingestion of hard or partially chewed food. (Refer to Limited Causes of Hematemesis.)
Although the severity of hematemesis depends on the quantity, origin, and speed of the bleeding, it is always a reliable indicator. Profound hematemesis, characterized by the vomiting of 500 to 1,000 mL of blood, can be potentially fatal.
Urgent medical interventions
Should the patient exhibit severe hematemesis, assess his vital signs. If indications of shock are observed, such as constricted breathing, low blood pressure, and rapid heart rate, arrange the patient in a supine posture and raise his feet by 20 to 30 degrees. Initiate a large-bore intravenous line for urgent fluid replenishment. Submit a blood sample for typing and cross-matching, measure hemoglobin level and hematocrit, and provide oxygen therapy. An emergency endoscopy may be required to identify the origin of the bleeding. Make necessary arrangements to introduce a nasogastric (NG) tube for the purpose of suction or cooled lavage. One may use a Sengstaken-Blakemore tube to compress esophageal varices.
Historical Background and Physical Assessment
When the patient's hematemesis is not immediately life-threatening, start by obtaining a comprehensive medical history. First, ask the patient to provide a description of the quantity, hue, and texture of the vomit. When did he initially become aware of this sign? Has the patient previously had hematemesis? Determine whether he also experiences profuse or dark, tarry feces. Record whether hematemesis is typically preceded by symptoms such as nausea, flatulence, diarrhea, or weakness. Has he experienced recent episodes of retching accompanied by or without vomiting?
Then, inquire if any prior occurrence of ulcers or liver or coagulation abnormalities. Ascertain the extent of alcohol consumption by the patient, if any. Is he a habitual user of aspirin or more nonsteroidal anti-inflammatory drugs (NSAIDs), such as phenylbutazone or indomethacin? These medications can induce erosive gastritis or ulcers. Has he been prescribed warfarin or any other medications with anticoagulant properties? These medications heighten the patient's susceptibility to hemorrhaging.
The physical examination should commence by assessing for orthostatic hypotension, which serves as an early indicator of hypovolemia. Obtain blood pressure and pulse measurements while the patient is lying on their back, seated, and standing. Volume depletion is indicated by a significant reduction of 10 mm Hg or more in systolic pressure or an increase of 10 beats/minute or more in pulse rate. Once further vital signs have been obtained, examine the mucous membranes, nasopharynx, and skin for any indications of bleeding or other irregularities. Ultimately, examine the abdomen by means of palpation to detect any soreness, pain, or lumps. Note lymph node involvement.
Managing Hematemesis with Intubation
A patient diagnosed with hematemesis will require the insertion of a gastrointestinal tube to enable blood drainage, aspirate gastric contents, or to promote gastric lavage, if required. The following are the prevailing tubes and their respective applications.
Nasogastric tubes
The Salem-Sump tube, a double-lumen nasogastric (NG) tube, is utilized for the purpose of extracting stomach fluid and gas or aspirating gastric contents during medical procedures. Further applications include gastrointestinal lavage, medication delivery, and feeding. A primary benefit of this tube compared to the Levin tube, which is a single-lumen NG tube, is its ability to let atmospheric air to enter the patient's stomach, enabling the tube to float freely instead of being at risk of adhering to and damaging the gastric mucosa.
Wide-bore gastric tubes
The Edlich tube, shown on the right, houses a single wide-bore lumen with four apertures located close to the closed distal end. A syringe or funnel can be attached at the proximal end. As with other tubes, the Edlich tube is suitable for gastric lavage and rapid aspiration of a substantial amount of stomach contents.
The Ewald tube, a wide-bore tube designed for rapid passage of a substantial volume of fluid and clots, is particularly beneficial for gastric lavage in patients experiencing excessive intragastrointestinal bleeding and those who have consumed non-acidic or alkaline poison. The double-lumen Levacuator is a wide-bore tube having a big lumen for evacuating stomach contents and a smaller one for lavage.
Esophageal tubes
At right, the Sengstaken-Blakemore tube is a triple-lumen double-balloon esophageal tube equipped with a stomach aspiration port that enables drainage from beneath the gastric balloon. It can also be utilized for the administration of medicine. Because it lacks an esophageal balloon, the Linton-Nachlas tube can aspirate esophageal and stomach contents without the risk of necrosis. The Minnesota esophagogastric mucosal tamponade tube, It consists of four lumina and two balloons, and includes pressure-monitoring ports for both balloons without requiring Y-connectors.
Medical etiology
Anthrax (GI) Initial indications and symptoms following the consumption of contaminated meat from an animal afflicted with the gram-positive, spore-forming causative agent Bacillus anthracis encompass reduced appetite, nausea, vomiting, and pyrexia. The signs and symptoms may advance to hematemesis, stomach discomfort, and serious hemorrhagic ulceration.
Coagulation disorders
Disruption of normal clotting by any disease can lead to gastrointestinal bleeding and moderate to severe hematemesis. Hemorrhage can also manifest in other bodily systems, leading to symptoms such as epistaxis and ecchymosis. Variations in other related effects are contingent upon the particular coagulation condition, such as thrombocytopenia or hemophilia.
Esophageal cancer
Indicative of advanced esophageal cancer, hematemesis might be accompanied by persistent chest pain that extends to the back. Other symptoms include substernal engorgement, intense difficulty swallowing, nausea, vomiting with regurgitation and aspiration during the night, coughing up blood, a fever, hiccups, a sore throat, melena, and excessive salivation.
Esophageal rupture
Incidence of hematemesis is determined by the underlying cause of the rupture. When a medical device causes injury to the esophagus, hematemesis is often rather mild. But rupture caused by Boerhaave's syndrome (increased pressure in the esophagus from vomiting or retching) or other esophageal diseases usually results in more severe hematemesis. Furthermore, this potentially fatal condition can cause intense retrosternal, epigastric, neck, or scapular pain along with swelling in the chest and neck. Clinical examination shows the presence of subcutaneous crepitation in the chest wall, supraclavicular fossa, and neck. In addition, the patient may exhibit indications of respiratory distress, such as decreased breathing and the appearance of cyanosis.
Esophageal varices (ruptured)
The rupture of esophageal varices can result in life-threatening vomiting that is either coffee-ground or large, brilliant crimson in character. Following or even preceding hematemesis, signs of shock such as hypotension or tachycardia may manifest if the stomach becomes filled with blood before vomiting takes place. Other symptoms may include stomach distension and melena, or painless hematochezia, which can range from little leaking to significant rectal bleeding.
Gastrointestinal carcinoma
Vomitus that is painless, brilliant red, or dark brown in color is a delayed indication of stomach cancer, sometimes originating gradually alongside upper abdominal pain. The patient then experiences anorexia, low-grade nausea, and persistent dyspepsia that is not alleviated by antacids and worsened by meals. Subsequent symptoms may encompass exhaustion, debility, reduction in body weight, sensations of satiety, melena, changes in bowel patterns, and indications of malnutrition, such as breakdown of muscles and dry skin.
Gastritis (acute)
Haematemesis and melena are the predominant manifestations of acute gastritis. While these symptoms may be the sole indications, modest epigastric discomfort, nausea, fever, and malaise may also manifest. Profound blood loss triggers symptoms of shock. Usually, the patient has a documented record of alcohol misuse or has prior usage of aspirin or another nonsteroidal anti-inflammatory drug (NSAID). Malignant gastritis can also result from infection with Helicobacter pylori.
Mallory-Weiss syndrome
Marked by a rupture of the mucosal lining at the point where the esophagus and stomach meet, this condition can result in hematemesis and melena. Gastroesophageal reflux is often precipitated by intense vomiting, retching, or straining (such as from coughing), often in individuals with alcoholism or pyrexia. Intensive hemorrhaging can trigger symptoms of shock, including rapid heart rate, low blood pressure, difficulty breathing, and cold, damp skin.
Peptic ulcer
When a peptic ulcer infiltrates an artery, vein, or highly vascular tissue, hematemesis may result. Hematemesis of significant magnitude, and potentially life-threatening, is characteristic when an artery is breached. Other characteristics include melena or hematochezia, chills, a fever, and indications of shock and dehydration, such as rapid heart rate, low blood pressure, dry skin, and excessive thirst. The patient may have a clinical record of experiencing nausea, vomiting, discomfort in the epigastric region, and pain that is alleviated by dietary intake or antacids. Moreover, he may have a documented record of regularly consuming tobacco, alcohol, or NSAIDs.
Treatments
Hematemesis could be caused by traumatic NG or endotracheal intubation resulting in the ingestion of blood. The manifestation of this symptom may also be induced by nose or throat surgery in a similar manner.
Points of Special Consideration
Rigorously observe the patient's vital signs and be vigilant for indications of shock. Routinely examine the patient's feces for hidden blood, and maintain precise records of their food consumption and stool production. In order to avoid aspiration of vomitus, put the patient in a low or semi-Fowler's position when on bed rest. Retain suctioning equipment in close proximity and utilize it as necessary. The provision of regular dental hygiene and mental support is crucial, since the sight of bloody vomitus can evoke significant fear. Dispense an intravenous histamine-2 receptor antagonist; vasopressin may be necessary for variceal bleeding. Monitor the pH of gastrointestinal contents when the bleeding subsides, and administer hourly doses of antacids via NG tube, as needed.
Educational Instruction for Patients
Detail the specific meals and fluids that the patient should refrain from consuming, and emphasize the need of abstaining from alcohol.
Guidelines for Pediatric Populations
Hematemesis is less prevalent in children compared to adults and may be associated with the consumption of foreign bodies. At times, newborns may experience hematemesis when they ingest maternal blood during delivery or when they breastfeed from a prolapsed nipple. Infants with hemorrhagic illness of the newborn and esophageal erosion may experience hematemesis, necessitating prompt intervention with fluid replacement.
Guidelines for Geriatrics
Hematemesis in an older population can result from a vascular abnormality, an aortoenteric fistula, or upper gastrointestinal malignancy. Furthermore, the presence of chronic obstructive lung disease, chronic liver or renal failure, and chronic NSAID usage all increase the risk of bleeding in older individuals due to the simultaneous occurrence of ulcerative diseases.
