Clinical Diagnosis: Superficial Thrombophlebitis (Mondor-type / IV-site related)

What the Image Shows

• A purple-violaceous discoloration following the course of a superficial vein (likely the cephalic vein)
• A visible puncture mark near the wrist (consistent with IV cannula insertion site)
• The patient appears to be in a clinical/hospital setting

Differential Diagnoses (in order of likelihood)

Most Probable Diagnosis

Management

• Remove IV cannula if still in situ
• Warm compresses to the affected area
• Elevation of the limb
• NSAIDs (e.g., ibuprofen) for pain/inflammation
• Monitor for signs of infection (warmth, purulence, fever)
• Reassure patient - ecchymosis typically resolves in 1-2 weeks

Important disclaimer: This is a visual assessment only and does not replace clinical examination. A clinician should assess the patient directly, palpate for a cord-like vein, check for warmth/tenderness, and consider Doppler ultrasound if deep vein thrombosis cannot be excluded.

IV-Related Thrombophlebitis: Recent Clinical Guidelines & Evidence

1. Definition & Classification

• Sabiston Textbook of Surgery, 21st ed., "Superficial Venous Thrombophlebitis"

2. Current Guidelines on Management

A. First-Line: Conservative (Local) Treatment

B. 2025 ASH/ISTH Pediatric Guideline (New - June 2025)

Recommendation 12a: For pediatric patients with SVT secondary to IV cannulation in the upper limb, the panel suggests NO anticoagulation rather than using anticoagulation. (Conditional recommendation; very low certainty evidence)

Recommendation 12b: For SVT not related to cannula (lower limb, cancer-associated, varicose veins), the panel suggests anticoagulation. (Conditional recommendation; very low certainty evidence)

C. When Anticoagulation IS Required (Extensive SVT)

• Fondaparinux 2.5 mg SC daily for 6 weeks (preferred based on CALISTO trial evidence)
• Enoxaparin 60 mg SC daily ("intermediate dose") for 6 weeks as alternative
• Rivaroxaban 10 mg daily x 45 days - shown non-inferior to fondaparinux in the SURPRISE trial (oral option, more convenient)

• Sabiston Textbook of Surgery, "Superficial Venous Thrombophlebitis"

"No study has demonstrated clear benefit for systemic anticoagulation of brachial vein thrombosis. It is reasonable to treat these clots similarly to superficial thrombophlebitis of the leg."

• Rosen's Emergency Medicine, 10th ed., "Upper Extremity Venous Thromboses"

D. Australian Commission Clinical Care Standard (ACSQHC, 2023)

• PIVCs should be replaced based on clinical indication (signs of phlebitis/infection), not routine scheduled replacement
• The device site should be assessed at least once daily
• PIVC should be removed immediately when signs of thrombophlebitis appear
• Forearm sites preferred over dorsum of hand (lower phlebitis risk)
• Avoid cubital fossa sites if possible; re-site as soon as appropriate

3. Prevention - What the Evidence Says

• Scheduled catheter removal may lower phlebitis incidence vs. clinically-indicated removal (RR 0.74; 10 RCTs) - but evidence certainty was low
• Wearing gloves at insertion reduces adverse events (RR 0.52)
• Chlorhexidine skin prep reduces phlebitis scores in neonates
• For most other preventive measures, evidence was insufficient to make strong recommendations
• The review concluded: "adherence to standard precaution measures and documentation remain the most important principles"

4. Phlebitis Grading Scale (VIP Scale - Clinical Tool)

5. Summary of Key Guideline Recommendations

Disclaimer: These guidelines are for educational reference. Clinical decisions should integrate the individual patient's full clinical context, comorbidities, and a treating clinician's direct assessment.

Acute Gastroenteritis (AGE) with Some Dehydration

1. Understanding "Some Dehydration" (WHO Classification)

• Rosen's Emergency Medicine, 10th ed., "Oral Rehydration Therapy"; Tintinalli's Emergency Medicine, 10th ed., "Treatment"

2. Management: WHO Plan B (Some/Moderate Dehydration)

Step 1 - Oral Rehydration Therapy (ORT)

• Sodium: 75 mmol/L
• Glucose: 75 mmol/L
• Chloride: 65 mmol/L
• Potassium: 20 mmol/L
• Citrate: 10 mmol/L
• Osmolarity: 245 mOsm/L

ORT is effective even if the patient continues to vomit - administer in small, frequent amounts (e.g., 5 mL every 1-2 min by spoon in infants).

• Rosen's Emergency Medicine, "Oral Rehydration Therapy"

Step 2 - Reassess After 4 Hours

• If improved (no dehydration signs) → move to Plan A (maintenance at home)
• If still "some dehydration" → repeat Plan B
• If worsened to severe dehydration → escalate to Plan C (IV fluids)

3. When to Switch to IV Fluids (Plan C escalation)

• Severe dehydration or shock (>10% loss, cold peripheries, prolonged CRT)
• Persistent vomiting despite small-volume ORT
• Altered consciousness / lethargy
• Suspected intestinal obstruction or acute abdomen
• Sodium derangement (hypernatremia or hyponatremia)
• ORT failure after 4-hour trial

• Ringer's Lactate (Hartmann's solution) - preferred
• Normal saline (0.9% NaCl) as alternative
• Severe dehydration IV regimen: 100 mL/kg RL over 3 hours in children (30 mL/kg fast bolus over 30 min, then 70 mL/kg over 2.5 hours); reassess every 30 min

"For patients with severe dehydration, isotonic intravenous fluids should be used, and lactated Ringer solution is the preferred commercially available option."

• Red Book 2021, "Vibrio cholerae"

4. Additional Treatment Measures

Antiemetics

• Ondansetron (oral/IV) - reduces vomiting, reduces need for IV fluids, reduces ED admission
  • Children: 0.15 mg/kg PO/IV once (max 8 mg)
  • Adults: 4-8 mg PO/IV
• Metoclopramide as second line

Antiemetics reduce vomiting, ED length of stay, and admission need. - Tintinalli's EM

Zinc Supplementation (Children, especially <5 yrs in low-income settings)

• 20 mg/day x 10-14 days (>6 months)
• 10 mg/day x 10-14 days (<6 months)
• Reduces duration and severity of diarrhea

Antimotility Agents

• Loperamide - safe in adults for mild-moderate nonbloody diarrhea; reduces illness duration
• AVOID in: children, dysentery (bloody diarrhea + fever), suspected STEC O157 infection

Probiotics

• Some evidence for Lactobacillus rhamnosus GG and Saccharomyces boulardii reducing duration by ~1 day in children (adjunctive use)

Feeding / Nutrition

• Do NOT withhold food - early refeeding encouraged once vomiting controlled
• Continue breastfeeding in infants throughout illness
• Age-appropriate diet should resume as soon as tolerated
• Avoid high-sugar drinks (juice, sports drinks, sodas) as sole replacement - they are not suitable ORS substitutes

5. Antibiotics - When to Use

NEVER give antibiotics if STEC (O157:H7) is suspected - increases risk of Hemolytic Uremic Syndrome (HUS).

6. Investigations

Routine stool testing is NOT indicated for uncomplicated watery diarrhea. - Tintinalli's EM, 10th ed.

7. Admission Criteria

• Severe dehydration unresponsive to ORT
• Persistent vomiting making ORT impossible
• Altered mental status
• Systemic symptoms (high fever, signs of sepsis)
• Significant comorbidities (immunocompromised, IBD, renal failure)
• Infants <6 months with any dehydration
• Failure to improve after 4-hour Plan B trial
• Bloody diarrhea with toxaemia

• Tolerating ORS
• No signs of dehydration after treatment
• Caregiver able and willing to continue ORT at home
• Clear follow-up instructions given

8. Patient/Caregiver Education (Plan A - Discharge Instructions)

1. Give extra ORS or fluids after every loose stool: 50-100 mL for infants, 100-200 mL for older children/adults
2. Continue feeding normally - do not restrict diet
3. Return immediately if: child becomes more unwell, unable to drink, bloody diarrhea, high fever, or no improvement after 2 days
4. Hand hygiene - frequent handwashing to prevent household spread
5. Zinc supplementation course in children (developing world settings)

Clinical note: "Some dehydration" on WHO assessment mandates supervised Plan B ORT. Most patients respond well within 4 hours without IV fluids. The key is frequent reassessment and early escalation if ORT fails.
