Treatment of Subarachnoid Hemorrhage

Subarachnoid hemorrhage is bleeding into the subarachnoid space surrounding the brain, most often caused by a ruptured cerebral aneurysm. It classically presents with a sudden, severe thunderclap headache described as the worst headache of life, accompanied by nausea, vomiting, and neck stiffness.

First-Line Treatment Principles

✓Establish confirmed diagnosis before initiating treatment
✓Consider patient preferences, comorbidities, and drug interactions when selecting therapy
✓Start at lower doses in elderly, renal impairment, or hepatic impairment; titrate to response
✓Review treatment indication at regular intervals; deprescribe when indication resolved
✓Lifestyle modification as adjunct or first-line for most chronic conditions

Non-Pharmacological Management

•Diet: evidence-based nutritional approach specific to the condition
•Regular physical activity: 150 min/week moderate intensity aerobic exercise for most adults
•Smoking cessation: reduces risk across virtually all disease categories
•Alcohol restriction: moderate consumption (≤14 units/week) where medically indicated
•Weight management: maintains BMI 18.5–25 kg/m²
•Stress management and sleep hygiene
•Self-management education and patient empowerment

Treatment Goals

🎯Symptom control and quality-of-life improvement

🎯Prevention of complications and disease progression

🎯Minimise treatment burden and adverse effects

🎯Patient-centred shared decision making

Monitoring Parameters

◆Condition-specific biomarkers and clinical parameters at each review
◆Side effect monitoring according to drug class
◆Functional status and quality-of-life assessment
◆Treatment adherence: review at every encounter

Escalation Criteria

→Inadequate response after adequate trial period → second-line therapy or specialist referral
→Adverse drug reactions or tolerance issues → review and switch therapy
→Acute deterioration or new complications → emergency assessment

Special Populations

Elderly: polypharmacy risk, renal/hepatic dose adjustments, falls risk assessment

Pregnancy: check safety of all medications; specialist review if on multiple agents

Children: weight-appropriate dosing; developmental monitoring
