Practice Context

Registered nurses are the primary applicators of medicinal leeches in hospital settings. All nursing care proceeds under physician orders.

Медсёстры играют центральную роль в гирудотерапии — от предпроцедурной оценки пациента до наблюдения после выписки. Данные протоколы предоставляют специализированные сестринские рекомендации для безопасного и эффективного проведения гирудотерапии.

Предпроцедурная оценка

Patient Assessment Checklist

Verify physician orders (number of leeches, application sites, frequency)
Confirm signed informed consent in medical record
Review baseline labs: CBC, PT/INR, aPTT, type and screen
Verify antibiotic prophylaxis initiated (ciprofloxacin or TMP-SMX)
Check allergy history: antibiotics, latex, prior leech reactions
Assess current medications: anticoagulants, antiplatelets, NSAIDs
Obtain baseline vital signs (BP, HR, O2 sat, temperature)
For surgical patients: assess tissue color, capillary refill, Doppler signal

Contraindication Screen

Absolute:

Arterial insufficiency at application site
Hemophilia or hemorrhagic diathesis
Severe anemia (Hgb <8 g/dL without transfusion)
Active sepsis
Decompensated hepatobiliary disease

Relative:

Pregnancy, immunosuppression
Anticoagulant therapy (coordinate with surgeon)
Platelets <50,000/μL
INR >3.0

Step-by-Step Application

Prepare environment: Post “No Fragrances” notice. Ensure room temperature 72-77°F. Position patient comfortably.
Don PPE: Nitrile gloves (mandatory), gown if splash risk, eye protection for head/neck applications.
Prepare site: Cleanse with warm water only — no alcohol, betadine, chlorhexidine, or scented soaps.
Select leeches: Active, mobile, strong contraction reflex, smooth body, 6-10 cm extended.
Apply: Transfer leech to small clean container. Invert over prepared site. Once feeding begins, cover loosely with gauze.
Alternative (syringe guide): Remove plunger from 5-10 mL syringe. Place leech inside barrel. Press tip to skin at exact target.
If leech refuses: Ensure warm, chemical-free skin. Prick with sterile needle for blood droplet. Try a different leech.

NEVER leave patient unattended with applied leeches. NEVER forcibly remove a feeding leech.

Параметры мониторинга

Parameter	Frequency	Action Threshold
Vital signs	Every 30 min	SBP <90 or HR >120: evaluate for hypovolemia
Tissue assessment	Every 30 min	Document color, turgor, capillary refill, Doppler
Hematocrit	Every 4-8 hours	Hgb <7: transfuse. Hgb 7-8: clinical judgment
Leech feeding status	Continuous	Document attachment time, duration, detachment
Post-detachment bleeding	Every 1-2 hours x 6 hours	See excessive bleeding protocol
Pain (NRS 0-10)	Every 2 hours	>5: acetaminophen; avoid NSAIDs

Уход после отделения

Wound Dressing

Apply clean, dry gauze (4x4) over bite — no pressure
Layer additional absorbent pads
Secure with tape or light wrap — no compression
When saturated, add layers on top — DO NOT remove underlying dressing for 24 hours
Place absorbent underpads beneath treatment area

Expected: Oozing 4–24 hours. Prolonged oozing is expected and therapeutic.

Leech Disposal

Place detached leech in 70% ethyl alcohol
Confirm death (no movement for 5 min)
Transfer to red biohazard waste container
Seal and label per OSHA standards

NEVER reuse a leech. NEVER return fed leech to storage.

Распознавание осложнений

Infection Signs (Notify MD)

Expanding erythema disproportionate to expected inflammation
Purulent discharge from bite wound
Increased warmth, tenderness, induration
Fever, leukocytosis, elevated CRP
Tissue color change, turgor loss
Maintain vigilance for 26 days post-last application

Emergency Situations

Anaphylaxis: Epinephrine IM, activate emergency response

Excessive bleeding: Pressure, silver nitrate, topical thrombin, suture if refractory
Vasovagal syncope: Trendelenburg position, monitor vital signs
