Ukopha emathunjini: ukuhlanza igazi kanye nendle emnyama¶

I-acute gastrointestinal (GI) ukopha yisimo esiphuthumayo sezokwelapha lapho igazi liphuma emithanjeni yegazi ephukile, isilonda, noma ukudabuka noma yikuphi eduze komgudu wokugaya ukudla, kusukela emphinjeni nasesiswini (**i-GI engenhla yokopha **) kwehle kuze kufike emathunjini amancane, ikholoni, kanye ne-rectum (i-GI ephansi yokopha). Ngokungafani nesilonda sangaphandle engalweni noma emlenzeni, awukwazi ukucindezela izandla zakho ngqo esilonda esiswini esophayo noma i-varix esophageal ephukile, futhi isisu namathumbu kungafihla buthule 1,000 kuya ku-2,000 milliliters (2 kuya ku-4 pints) wegazi ngaphambi kokuba iconsi elilodwa lihlanzwe noma lidluliselwe endlini yangasese. Kungakhathaliseki ukuthi othile uhlanza igazi elibomvu ngokugqamile noma izinto ezimnyama "ze-coffee-ground" (hematemesis), udlula indle enamathelayo e-jet-black tarry (melena), noma ukhipha inani elikhulu le-maroon noma igazi elibomvu eligqamile eliphuma ku-rectum (hematochezia), izinto eziza kuqala kuwe ngokushesha zibiza izinsizakalo zezokwelapha eziseceleni, kumuntu oshonile. igazi, ukuwagcina ngokuqinile kungekho lutho ngomlomo (NPO), nokuwabeka phansi ukuze kuvinjwe ukufa ukushaqeka kwe-hypovolemic.

Yenza lokhu manje¶

1. Call your local emergency number immediately if the person is vomiting blood, passing black tarry stools with dizziness, or bleeding heavily from the rectum. Dial 911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom, or see all izinombolo eziphuthumayo. Tell the dispatcher whether the patient is vomiting bright red blood, has liver cirrhosis, or takes blood thinners (anticoagulants), as this triggers advanced paramedic airway and blood-transfusion protocols.
2. Protect the airway by placing any vomiting or drowsy person on their side (Recovery Position). If the person is actively vomiting blood (hematemesis), retching, or becoming drowsy, confused, or unconscious, immediately roll them onto their left side into the lateral recovery position and tilt their chin slightly downward so blood and clots drain freely out of the corner of their mouth into a basin or towel. Use a finger wrapped in a cloth to sweep any large rubbery blood clots out of the front of their mouth if they are gagging.
3. Lay a non-vomiting, dizzy person flat on their back to prevent fainting and shock. Do not allow a person with suspected GI bleeding to walk down stairs, stand at the bathroom sink, or sit upright on the toilet if they feel lightheaded. Standing upright when blood volume is depleted causes blood pressure to plummet (orthostatic syncope), leading to sudden collapse, severe head injuries on bathroom tiles, and cardiac arrest. If they are fully alert and not nauseated or vomiting, lay them flat on the floor or bed.
4. Give strictly NOTHING by mouth (no water, no milk, no antacids, and never aspirin or NSAIDs). Do not let the person drink water, milk, or herbal teas, and do not give oral antacids or bismuth. Most importantly, never give aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), diclofenac, or ketorolac for stomach pain: these nonsteroidal anti-inflammatory drugs (NSAIDs) strip away the stomach's protective mucus barrier and paralyze blood platelets, turning a slow ulcer bleed into a torrential arterial hemorrhage.
5. Keep the person warm with blankets to protect blood clotting. Cover the patient with a warm blanket or coat and place a blanket underneath them if they are lying on a cold bathroom floor. When a bleeding patient becomes cold (hypothermia below \(35^\circ\text{C}\) or \(95^\circ\text{F}\)), the enzymatic clotting cascade and blood platelets stop working properly (part of the "Lethal Triad of Trauma and Hemorrhage"), causing uncontrollable bleeding.
6. Save a sample or take a smartphone photo of the vomit or stool, and gather all medication bottles. Before flushing the toilet or throwing away a basin of vomit, snap a clear photograph with your phone or save the container to show paramedics (doctors need to see the exact color, clots, and estimated volume). Gather every prescription and over-the-counter bottle in the house, specifically checking for blood thinners (warfarin, apixaban, rivaroxaban, dabigatran, clopidogrel), aspirin/NSAIDs, steroids, and iron or bismuth supplements.

Decoding the 4 visual patterns of GI bleeding: What color tells you¶

As blood travels through the human digestive tract, stomach hydrochloric acid, digestive enzymes (pepsin), and intestinal bacteria chemically alter the red hemoglobin molecule inside red blood cells, changing its color from bright crimson to dark brown-black. By looking closely at what was vomited or passed into the toilet, you can pinpoint where the bleeding is coming from and how fast it is happening.

False alarms: Distinguishing real blood from harmless food and pill staining ("Pseudomelena")¶

Before panicking over a dark or reddish stool in someone who feels completely healthy, has a normal pulse, and has zero dizziness or stomach pain, check whether they consumed one of these common mimics in the past 24 to 48 hours:

• Harmless mimics of Black Melena ("Pseudomelena"):
• Oral Iron Supplements (ferrous sulfate, ferrous gluconate, prenatal vitamins): Turns stool a dark greenish-black color, but the stool has a normal firm shape (not sticky tar) and lacks the putrid odor of digested blood.
• Bismuth Subsalicylate (Pepto-Bismol, Kaopectate): Bismuth reacts with trace sulfur in saliva and the gut to form black bismuth sulfide, often turning both the tongue and the stool jet-black.
• Activated Charcoal, black licorice, dark chocolate/Oreo cookies, or large bowls of dark blueberries/grape juice.
• Harmless mimics of Red Hematochezia / Red Vomit:
• Red beets (beetroot / betanin pigment), red gelatin (Jell-O), Kool-Aid / red sports drinks, red food coloring, dragon fruit, or large amounts of tomato sauce.
• Safety Rule: If there is any doubt whatsoever, or if the person has stomach pain, weakness, sweating, or takes aspirin/blood thinners, always treat it as real blood and go to the emergency room (a 30-second hospital fecal occult blood test or hemoglobin fingerstick settles the question immediately).

Major causes of upper and lower gastrointestinal bleeding¶

Understanding what causes GI bleeding helps you give critical medical history to the paramedics and emergency physicians.

1. Upper GI bleeding causes (75% to 80% of all hospital GI bleed admissions)¶

• Peptic Ulcer Disease (Gastric and Duodenal Ulcers: 40% to 50% of upper bleeds): Deep sores eroded into the lining of the stomach or the first part of the small intestine (duodenum), almost always caused by either Helicobacter pylori (H. pylori) bacterial infection or regular use of NSAID painkillers (ibuprofen, naproxen, aspirin, meloxicam, diclofenac). When an ulcer eats down into the submucosa and erodes the wall of a major artery (such as the gastroduodenal artery behind the duodenum or the left gastric artery), blood spurts under high arterial pressure into the gut.
• Esophageal and Gastric Varices (10% to 20% of upper bleeds, highest mortality): In patients with liver cirrhosis (from alcohol use, hepatitis B or C, or fatty liver disease) or portal vein thrombosis, scar tissue in the liver blocks normal blood flow from the intestines. Pressure backs up in the portal vein (portal hypertension), forcing blood to detour through fragile, thin-walled veins lining the lower esophagus and upper stomach (varices), which swell like varicose veins. When a varix ruptures, it causes painless, explosive projectile vomiting of hundreds of milliliters of bright red blood and carries a 15 to 20 percent mortality rate per bleeding episode.
• Mallory-Weiss Tear (5% to 15% of upper bleeds): A longitudinal laceration (tear) in the mucous membrane at the junction where the esophagus meets the stomach, triggered by violent retching, dry heaving, or forceful vomiting (after heavy alcohol binge drinking, food poisoning, hyperemesis gravidarum in pregnancy, or severe coughing fits). Typically starts with several episodes of normal vomit followed suddenly by bright red blood.
• Erosive Gastritis, Esophagitis, and Dieulafoy Lesion: Diffuse pinpoint bleeding from severe acid reflux, alcohol, critical illness stress, or a Dieulafoy lesion (an abnormally large, tortuous submucosal artery in the upper stomach that erodes through a tiny mucosal defect and causes massive sudden bleeding without an ulcer).

2. Lower GI bleeding causes (Colon, Rectum, and Small Bowel)¶

• I-Diverticular Bleeding (I-Diverticulosis: 30% kuya ku-50% yokopha okuphansi ngokushesha): I-herniations efana nesikhwama esincane (diverticula) odongeni lwe-muscular colon, oluvame kubantu abadala abaneminyaka engaphezu kwengu-50, yakheka lapho imithambo yezakhi zomzimba ingena khona (i-vasa coloni). Uma umthambo we-vasa recta ongaphakathi kwe-diverticulum ugqabuka, ubangela ukudlula kungazelelwe, okungenabuhlungu ngokuphelele kwenani elikhulu le-maroon noma igazi elibomvu elikhanyayo kanye namahlule endlini yangasese.
• I-Angiodysplasia (I-Vascular Ectasias): Izingqimba ezintekenteke, ezisontekile zama-capillaries anwetshiwe kanye nemithambo esodongeni lwekholoni elingakwesokudla noma emathunjini amancane, avamile kubantu abadala asebekhulile, iziguli ezinesifo sezinso esingamahlalakhona, noma iziguli ezine-aortic stenosis (Heyde's syndrome).
• I-Ischemic Colitis, Isifo Samathumbu Esivuvukalayo (I-Ulcerative Colitis / Crohn's Disease), kanye Ne-Infectious Colitis: Ngokungafani nokopha kwe-diverticular (okuvame ukungabi nabuhlungu), lezi zimo zibangela izinhlungu ezihlabayo ezingezansi zesisu ezihambisana nesifo sohudo esinegazi noma amafinyila.
• Colorectal Polyps and Colorectal Cancer: Ngokuvamile kubangela ukugeleza okuhamba kancane, okungamahlalakhona okuholela ku-anemia yokuntuleka kwensimbi, noma imicu ebomvu emnyama exutshwa endwangu yendle.
• Ama-hemorrhoids kanye Nokufiphazeka Kwendunu: Imithambo evuvukele kumsele wendunu (ama-hemorrhoids) noma ukudabuka okubukhali kolwelwesi lwendunu (umfantu, okuzwakala njengokuthi "udlula ingilazi ephukile" phakathi nokukhipha amathumbu) ngokuvamile kuvame ukumboza indle noma aconsele igazi elibomvu ephepheni lasendlini yangasese ngemva kokusula.

Ukubona ukushaqeka kwe-hypovolemic: Kungani umfutho wegazi ojwayelekile ungaba amanga¶

Umzimba womuntu omdala uphethe cishe5,000 milliliters (5 amalitha / 10.5 pints) wegazi. Lapho umuntu opha esiswini noma kukholoni, umzimba ngokushesha ukhipha i-adrenaline egijima ukuze ibophe imithambo yegazi futhi isheshise inhliziyo, okugcina umfutho wegazi we-systolic ubukeka ngendlela ekhohlisayo kuze kube yilapho isiguli sesilahlekelwe kakade ngamaphesenti angu-30 (1.5 amalitha) egazi laso.

Sebenzisa isigaba se-American College of Surgeons Advanced Trauma Life Support (ATLS) ukuze ubone ukushaqeka kwangaphambi kwesikhathi ngaphambi kokuphahlazeka komfutho wegazi:

Izixwayiso ezibucayi: I-cirrhosis yesibindi, okokunciphisa igazi, kanye ne-aortoenteric fistula¶

Uma umuntu owophayo engowanoma yiliphi kulawa maqembu amathathu asengozini enkulu, yazisa i-911/112/999 dispatcher kanye nabezimo eziphuthumayo emshweni wakho wokuqala:

1. Isifo Sesibindi Esaziwayo Noma Esisolekayo / I-Cirrhosis (I-Variceal Bleed): Bheka amehlo/isikhumba esiphuzi (jaundice), isisu esigcwele uketshezi (ascites), imithambo yegazi ebomvu efana nesicabucabu esifubeni (spider angiomata), noma izintende ezibomvu (klzzwxh:0082). I-Variceal hemrhage idinga i-intravenous terlipressin noma i-octreotide**asesibhedlela esheshayo (ukwehlisa umfutho we-portal vein), prophylactic IV ama-antibiotics (ceftriaxone), kanye ne-endoscopic variceal band ligation ephuthumayo phakathi namahora angu-12.
2. Patients Taking Anticoagulants ("Blood Thinners") or Dual Antiplatelet Therapy: Check if the patient takes warfarin (Coumadin), Direct Oral Anticoagulants (apixaban [Eliquis], rivaroxaban [Xarelto], edoxaban [Savaysa], dabigatran [Pradaxa]), or antiplatelets (clopidogrel [Plavix], prasugrel, ticagrelor, aspirin). Hospital emergency departments carry specific intravenous reversal antidotes (4-factor Prothrombin Complex Concentrate [Kcentra/Beriplex] + IV Vitamin K for warfarin; andexanet alfa for apixaban/rivaroxaban; idarucizumab [Praxbind] for dabigatran) that can stop fatal bleeding if the medical team knows which pill the patient takes and when the last dose was swallowed.
3. Prior Abdominal Aortic Aneurysm (AAA) Graft Surgery ("Herald Bleed" of an Aortoenteric Fistula): If a person who has ever had an open or endovascular surgical graft placed on their abdominal aorta develops any gastrointestinal bleed (even a small, self-stopping episode of hematemesis or melena), it is a surgical emergency until proven otherwise. A synthetic aortic graft can slowly erode into the wall of the adjacent third part of the duodenum, creating an aortoenteric fistula; a small "herald bleed" is often followed hours or days later by catastrophic, fatal exsanguination directly from the aorta into the gut unless repaired in the operating room.

Ukucatshangelwa okukhethekile: ukopha kwe-GI yezingane kanye nokungeniswa kwebhethri yenkinobho¶

Lapho usana, usana, noma ingane endala ihlanza igazi noma idlula indle emnyama noma enegazi, zombili izimbangela kanye nomthamo wegazi obalulekile kuhluka kakhulu kwabadala. Ngenxa yokuthi umthamo wegazi elijikelezayo wengane ungamamililitha angu-70 kuya kwangu-80 kuphela ngekhilogremu yesisindo somzimba* (okusho ukuthi ingane enonyaka ongu-10 ubudala ine-750 millilitha yegazi eliphelele emzimbeni wayo wonke*), ilahlekelwa ngamamililitha angu-150 kuya kwangu-200 kuphela (ngaphansi kwenkomishi eyodwa ye-hypovole)

• Ibhethri Lenkinobho Egwinyile (Isimo Esiphuthumayo Se-Aortoesophageal Fistula): Uma ingane encane ihlanza ngisho neconsi elincane noma umugqa wegazi elibomvu ngokugqamile noma into egayiwe yekhofi, buza ngokushesha ukuthi ibingeke yini igwinye inkinobho yeseli ye-lithium yebhethri (ngisho nafika emavikini angu-2 kuya kwangu-4 adlule, njengokuwohloka kwebhethri ezinsukwini ezidlule. ukususa). Shayela ku-911 / 112 / 999 ngokushesha futhi unganikezi noma yini ngomlomo uma i-hematemesis seyenzekile.
• I-Intussusception ("I-Currant Jelly" Ezinsaneni Izinyanga Ezi-3 Kuya Eminyakeni Emi-3): Uma ingane noma ingane encane ivele idonse amadolo ayo esifubeni ngokuklabalasa kwezinhlungu zesisu njalo ngemizuzu engu-15 kuya kwengu-20, okulandelwa ukukhathala, ukuhlanza, nokuphuma koqweqwe olubomvu, amafinyila amnyama, amafinyila. ingxenye yamathumbu abo ibone ibonakude ngaphakathi kwenye (intususception). Lokhu kudinga i-ultrasound esibhedlela esiphuthumayo esiphuthumayo kanye nokunciphisa i-air-enema ukuvimbela i-necrosis yamathumbu kanye nokubhobozwa.
• Swallowed Maternal Blood or Epistaxis (Nosebleed) Blood: Sometimes a breastfeeding newborn vomits blood or passes dark stools simply from swallowing maternal blood from a cracked nipple, or an older child vomits coffee-ground blood after swallowing blood from a posterior nosebleed overnight. Even so, a doctor must evaluate the child to rule out true mucosal bleeding, Meckel's diverticulum (painless brick-red rectal bleeding in toddlers), or juvenile polyps.

What to expect in the hospital emergency department: Risk scores and endoscopic hemostasis¶

Knowing what happens once the ambulance arrives at the emergency room helps family members provide clear consent and medication histories:

1. Two Large-Bore Intravenous Lines and Restrictive Blood Transfusion: Emergency nurses immediately place two large-bore intravenous cannulas (16-gauge or 18-gauge) into the forearm or antecubital veins, draw blood for a complete blood count, coagulation panel (INR), lactate, and blood type/crossmatch, and infuse warm balanced crystalloid fluids (Ringer's lactate or \(0.9\%\) normal saline). Modern randomized clinical trials (validated by the ACG, ESGE, and UK NICE) show that a restrictive packed red blood cell transfusion threshold (transfusing when hemoglobin drops to \(7\text{ g/dL}\) [\(70\text{ g/L}\)] in most patients, or \(8\text{ g/dL}\) [\(80\text{ g/L}\)] in patients with active coronary heart disease) saves more lives than over-transfusing, because over-transfusing raises portal and arterial blood pressure and blows off newly formed clots.
2. Glasgow-Blatchford Score (GBS) and Intravenous Medication: Doctors calculate the Glasgow-Blatchford Score (using blood urea nitrogen, hemoglobin, systolic blood pressure, pulse rate, melena, syncope, liver disease, and heart failure) to determine severity. Patients receive high-dose intravenous proton pump inhibitors (such as pantoprazole or esomeprazole) to neutralize stomach acid so platelets can clot, prokinetic erythromycin (given 30 to 60 minutes before endoscopy to clear blood clots from the stomach view), and octreotide or terlipressin plus IV ceftriaxone if liver cirrhosis is suspected.
3. Endoscopic Hemostasis, Interventional Radiology, or Balloon Tamponade: Within 12 to 24 hours (or immediately after airway intubation in unstable patients), a gastroenterologist passes a flexible fiber-optic esophagogastroduodenoscope (EGD) down the throat to locate the bleeding vessel and seal it using metal hemoclips, thermal multipolar electrocoagulation, epinephrine injection, hemostatic powder spray (Hemospray), or elastic variceal rubber band ligation. If bleeding cannot be stopped endoscopically, interventional radiologists perform transcatheter arterial embolization (TAE) (threading a microcatheter through the femoral or radial artery to plug the bleeding branch with coils) or place a transjugular intrahepatic portosystemic shunt (TIPS) for refractory varices.
