Ukopha emathunjini: Ukugabha igazi kunye nelindle elimnyama¶

I-Acute gastrointestinal (GI) ukopha yimeko engxamisekileyo yonyango apho igazi liphuma kwisitya segazi esiqhekekileyo, isilonda, okanye ukukrazula naphi na ecaleni kwendlela yokugaya, ukusuka kwi-esophagus kunye nesisu (**i-GI ephezulu yopha **) ukuya kutsho kumathumbu amancinci, ikholoni, kunye ne-rectum (**i-GI ephantsi yopha **). Ngokungafani nesilonda sangaphandle kwingalo okanye emlenzeni, awukwazi ukucinezela izandla zakho ngokuthe ngqo kwisilonda sesisu esophayo okanye i-varix esophageal ruptured, kwaye isisu kunye namathumbu angakwazi ukufihla ngokuthula ** i-1,000 ukuya kwi-2,000 milliliters (2 ukuya kwi-4 pints) yegazi ** ngaphambi kokuba ithontsi elilodwa lihlanzwe okanye lidluliselwe kwindlu yangasese. Nokuba umntu ugabha igazi elibomvu eliqaqambileyo okanye izinto ezimnyama "zekofu-yomhlaba" (hematemesis), udlula i-jet-black tarry stools (melena), okanye ugqithise isixa esikhulu se-maroon okanye igazi elibomvu eliqaqambileyo eliphuma kwi-rectum (hematochezia), izinto eziphambili kuwe zingxamisekileyo zifowunela iinkonzo zonyango ezingxamisekileyo, ngoko ke umntu angatshoni phantsi. igazi, ukuwagcina ngokungqongqo akukho nto ngomlomo (NPO), kunye nokuwabeka phantsi ukuthintela ukufa umothuko we-hypovolemic.

Yenza oku ngoku¶

1. Fowunela inombolo yakho kaxakeka ngokukhawuleza ukuba umntu ugabha igazi, ukhupha ilindle elimnyama elinesiyezi, okanye wopha kakhulu kwi rectum. Cofa inombolo 911 eUnited States naseKhanada, 112 ngapha kweEuropean Union, 999 eUnited Kingdom, okanye ubone zonke amanani kaxakeka. 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: i-30% ukuya kwi-50% ye-brisk ephantsi kwegazi)**: I-herniations encinci ye-pouch-efana ne-pouch (**diverticula *) kudonga lwe-muscular colon, oluqhelekileyo kubantu abadala abangaphezu kweminyaka yobudala be-50, yenze kanye apho i-arteries yezondlo ezingenayo ( i-vasa recta udonga *). Ukuba i-vasa recta umthambo ongaphakathi kwi-diverticulum igqabhuka, ibangela ukudlula ngequbuliso, ngokungenantlungu kwaphela kwezixa ezikhulu zemaroon okanye igazi elibomvu eliqaqambileyo kunye namahlwili kwindlu yangasese.
• ** I-Angiodysplasia (i-Vascular Ectasias) : I-Fragile, i-twisted tangles ye-capillaries ehlanjululweyo kunye nemithambo eludongeni lwekholoni elungileyo okanye emathunjini amancinci, aqhelekileyo kubantu abadala, izigulane ezinesifo esingapheliyo sezintso, okanye izigulane ezine-aortic stenosis ( Heyde's syndrome **).
• I-Ischemic Colitis, i-Inflammatory Bowel Disease (I-Ulcerative Colitis / I-Crohn's Disease), kunye ne-Infectious Colitis: Ngokungafani nokopha kwe-diverticular (edla ngokungenabuhlungu), ezi meko zibangela ** iintlungu ezibuhlungu ezisezantsi zesisu ezidityaniswe norhudo olunegazi ** okanye i-mucus.
• I-Colorectal Polyps kunye ne-Colorectal Cancer: Ikholisa ukubangela ukucotha, ukugobhoza okungapheliyo okukhokelela kwi-anemia yokunqongophala kwesinyithi, okanye imivimbo ebomvu ephakathi edityaniswe kwilaphu lesihlalo.
• IiHemorrhoids kunye neeFissures zoMpundu: Imithambo edumbileyo kumjelo wokuphuma ezimpundu (ihemorrhoids) okanye ukukrazuka okubukhali kwilenja yangasese (intanda, evakala ngathi "yidlula iglasi eyophukileyo" ngexesha lokuhamba kwamathumbu) idla ngokugquma umphandle welindle okanye uthontsize igazi elibomvu eliqaqambileyo kwiphepha lendlu yangasese emva kokusula.

Ukuqaphela ukothuka kwe-hypovolemic: Kutheni uxinzelelo lwegazi oluqhelekileyo lunokuba bubuxoki¶

Umzimba womntu omdala uphethe malunga nama-5,000 eemililitha (iilitha ezi-5 / iiipinti eziyi-10.5) zegazi*. Xa umntu esopha esiswini okanye kwikholoni, umzimba ukhupha ngokukhawuleza i-adrenaline ukuze ithintele imithambo yegazi kwaye ikhawuleze intliziyo, nto leyo ** igcina uxinzelelo lwegazi lwe-systolic lukhangeleka ngokukhohlisayo de umguli sele elahlekelwe yi-30 ekhulwini (1.5 ilitha) yegazi labo **.

Sebenzisa i-American College of Surgeons Advanced Trauma Life Support (ATLS) ulwahlulo lwe-hemorrhage ukuze uqaphele ukothuka kwangaphambili ngaphambi kokuba uxinzelelo lwegazi luphazamise:
