I now have solid information from Tintinalli's Emergency Medicine. Let me give a thorough, accurate answer.
Important Disclaimer
This is general medical information only. A 20-year-old with stomach pain and fever needs a proper clinical evaluation before any medicine is given. The cause must be identified first - treating blindly can be harmful (e.g., giving pain relief before ruling out appendicitis can mask important signs).
Step 1: Rule Out Emergencies First
Before any medicine, certain dangerous causes must be excluded:
| Red Flag | Possible Cause |
|---|---|
| Pain starts around navel, moves to right lower abdomen | Appendicitis - requires surgery, NOT medicines |
| Very high fever (>39°C), severe tenderness, rigid abdomen | Peritonitis / perforation |
| Severe, sudden onset ("worst pain of life") | Bowel obstruction, mesenteric ischemia |
| Bloody diarrhea | Infectious colitis (Shigella, E. coli O157) |
If any red flags are present, go to the emergency room immediately.
Step 2: Most Likely Cause - Acute Gastroenteritis
If the history suggests stomach flu (viral/bacterial gastroenteritis) - nausea, vomiting, diarrhea, crampy pain, fever - here is the evidence-based approach:
A. Hydration (Most Important Treatment)
- Oral Rehydration Solution (ORS) - WHO-ORS or any electrolyte drink (e.g., Electral, Pedialyte)
- Drink small sips frequently; aim for at least 30 mL/kg/hour
- This is the cornerstone of treatment and reduces the need for IV fluids
(Tintinalli's Emergency Medicine, p. 889)
B. Fever and Pain Relief
- Paracetamol (Acetaminophen) 500-1000 mg orally every 6-8 hours as needed
- Safest choice for fever and mild-moderate pain
- Ibuprofen 400 mg orally every 8 hours (with food) - also works, but avoid if vomiting heavily or any concern about gastric ulcer
- Avoid Loperamide (Imodium) if fever is present - it can worsen bacterial infections by trapping the organism inside the gut
C. Anti-Nausea / Vomiting
- Ondansetron (Zofran) 4-8 mg orally - first-line antiemetic, well tolerated
- Domperidone 10 mg three times daily before meals - alternative
D. Antispasmodic (for crampy pain)
- Hyoscine butylbromide (Buscopan) 10-20 mg orally three times daily - relieves intestinal spasms
Step 3: Antibiotics - Only If Needed
Antibiotics are NOT needed for most cases (the majority are viral). Per Tintinalli's Emergency Medicine (p. 891):
| Situation | Antibiotic |
|---|---|
| Suspected Shigella (bloody diarrhea, high fever) | Azithromycin 500 mg day 1, then 250 mg x 4 days |
| Typhoid fever (stepladder fever, constipation, rose spots) | Azithromycin or Ceftriaxone |
| Cholera (rice-water stools, severe dehydration) | Doxycycline 300 mg single dose |
| H. pylori (peptic ulcer - burning epigastric pain, worsens with food) | Triple therapy: PPI + Amoxicillin + Clarithromycin x 14 days |
| Campylobacter (poultry exposure, bloody diarrhea) | Azithromycin 500 mg/day x 3 days (within 3 days of onset) |
Do NOT give antibiotics for Salmonella in an otherwise healthy person - evidence shows no benefit and it prolongs carrier state.
(Tintinalli's Emergency Medicine, p. 890-891)
Step 4: Diet and Recovery
- BRAT diet (Banana, Rice, Applesauce, Toast) or any bland food
- Avoid dairy, spicy, oily foods temporarily
- Avoid caffeine and alcohol
- Resume normal diet as soon as tolerated - starving is NOT recommended
When to Seek Immediate Medical Attention
- Fever >39°C that does not improve with paracetamol
- Severe, localized pain (especially right lower abdomen)
- Signs of dehydration (no urine output, dry mouth, dizziness)
- Vomiting that prevents any oral intake
- Symptoms persist beyond 48-72 hours
- Blood in stool or vomit
Bottom line: For a simple gastroenteritis, start with ORS for hydration + paracetamol for fever + ondansetron for vomiting + buscopan for cramps. See a doctor to confirm the diagnosis and determine whether antibiotics are needed.

I now have comprehensive textbook information. Here is the full answer:
Emergency #3: Severe Sudden-Onset Abdominal Pain
This covers two closely related surgical emergencies: Bowel Obstruction and Acute Mesenteric Ischemia (AMI). Both are life-threatening and require hospital care immediately.
PART A: Bowel Obstruction (Small or Large)
What is it?
The intestine is physically blocked, preventing food, gas, and fluid from passing. The bowel balloons up upstream and can rupture or lose its blood supply if untreated.
Classic Symptoms
- Sudden, severe, crampy abdominal pain (comes in waves)
- Vomiting (may look like fecal matter in late stages)
- Abdomen is distended and bloated
- No passage of gas or stool ("obstipation")
- High-pitched or absent bowel sounds
What to Do - Step by Step
Step 1: Call Emergency Services / Go to ER Immediately
Do not wait, do not eat or drink anything (keep the patient "nil by mouth" - NPO).
Step 2: Hospital Initial Management
(Maingot's Abdominal Operations)
| Action | Details |
|---|---|
| IV Fluids | Large amounts of normal saline (0.9% NaCl) or Lactated Ringer's solution - patients are severely dehydrated |
| Nasogastric (NG) tube | Inserted through the nose into the stomach to decompress (drain) the blocked bowel, relieve vomiting, and prevent aspiration |
| Electrolyte correction | Check and replace potassium, chloride - prolonged vomiting causes dangerous imbalances |
| Urine catheter | Monitor urine output to guide fluid resuscitation |
| Blood tests | Full blood count, electrolytes, lactate, renal function |
Step 3: Imaging
- X-ray abdomen (upright) - shows dilated bowel loops and air-fluid levels
- CT scan abdomen - confirms diagnosis, finds the exact location and cause of blockage
Step 4: Treatment Decision
| Situation | Treatment |
|---|---|
| Partial obstruction, no signs of strangulation | Conservative: NG tube + IV fluids + observation (62-85% resolve without surgery) |
| Complete obstruction | Surgery required |
| Signs of strangulation (bowel turning black/dying) - fever, severe continuous pain, peritonitis | Emergency surgery - bowel resection |
| Hernia causing obstruction | Surgical reduction and repair |
(Maingot's Abdominal Operations; Mulholland & Greenfield's Surgery)
PART B: Acute Mesenteric Ischemia (AMI)
What is it?
The blood supply to the intestines is cut off (blocked artery or vein), causing the bowel to die. Mortality exceeds 70% if bowel infarction occurs - this is one of the most dangerous abdominal emergencies.
Classic Symptoms
- "Pain out of proportion" - severe, excruciating abdominal pain but the abdomen may feel surprisingly soft at first
- Nausea, vomiting, diarrhea (sometimes bloody)
- Rapid deterioration - patient becomes severely ill within hours
What to Do - Step by Step
Step 1: Emergency Room - Immediate
| Action | Purpose |
|---|---|
| IV fluid resuscitation | Correct shock and volume depletion |
| Broad-spectrum antibiotics | Prevent sepsis from bacterial translocation through dying gut wall - e.g., a third-generation cephalosporin (Ceftriaxone) + Metronidazole + Piperacillin-Tazobactam |
| NPO (nothing by mouth) | Bowel rest |
| Monitor vitals closely | BP, pulse, urine output, oxygen |
(Goldman-Cecil Medicine, p. 1507)
Step 2: Urgent Imaging
- CT Angiography - the test of choice (95% sensitivity and specificity). Shows which vessel is blocked and whether bowel is dying. Done WITHOUT oral contrast.
- Plain X-ray may show "thumb-printing" (bowel wall thickening) or gas in the bowel wall (very bad sign)
- Gold standard if needed: Selective mesenteric angiography (also allows direct treatment)
Step 3: Treatment
| Finding | Action |
|---|---|
| Peritoneal signs / bowel necrosis on CT | Urgent exploratory laparotomy (open surgery) - dead bowel is resected |
| Arterial embolism (SMA) | Embolectomy (surgical clot removal) + Papaverine infusion (vasodilator, 60 mg bolus then 30-60 mg/hr for 12-48 hrs) to prevent spasm |
| Arterial thrombosis | Thrombectomy or surgical bypass + Papaverine |
| Nonocclusive ischemia | Papaverine or Alprostadil infusion into the mesenteric artery |
| Mesenteric venous thrombosis | Anticoagulation (heparin, then warfarin/DOAC) |
| Selected cases without surgery | Endovascular thrombolysis or stent placement |
Step 4: Long-Term Care
- Aspirin lifelong after surgery
- Dual antiplatelet therapy after endovascular intervention
- Address underlying causes: smoking cessation, statins for atherosclerosis, treat heart arrhythmias (AFib is a major cause of mesenteric embolism)
(Goldman-Cecil Medicine; Mulholland & Greenfield's Surgery, p. 4828)
Key Warning Signs That Mean "Go to ER NOW"
| Sign | What it Means |
|---|---|
| Sudden, severe, constant abdominal pain | Possible ischemia or perforation |
| Pain that is out of proportion to physical exam findings | Classic AMI |
| Rigid, board-like abdomen | Peritonitis - surgical emergency |
| Absence of bowel sounds | Late obstruction or ileus |
| Blood in stool + severe pain | Bowel infarction |
| Shock (low BP, rapid pulse, cold sweaty skin) | Life-threatening - call ambulance immediately |
The single most important action for both conditions: Do not delay - get to an emergency surgical hospital as fast as possible. Time is bowel, and bowel is life.
