Immediate stabilization
Time-critical threats
Airway compromise
Escalate to resuscitation bay for altered mental status with airway risk
If seizure, initiate seizure management protocol
Shock physiology
If hypotension with fever, initiate sepsis pathway
If suspected anaphylaxis, initiate anaphylaxis protocol
Malignant dysrhythmia
If syncope or chest pain with bradycardia, immediate ECG and continuous monitoring
If high-grade AV block, transcutaneous pacing readiness
Monitoring and access
Cardiac monitoring
Continuous telemetry for palpitations, syncope, chest pain, dyspnea
Repeat ECG for evolving conduction delay
Vitals trend
Temperature trend for persistent fever
Orthostatic vitals for presyncope
IV access
Two large-bore IV for unstable patients
Consider intraosseous access if unable to obtain IV and unstable
Early escalation triggers
Neuroborreliosis concern
If meningismus or focal deficit, emergent neurology consultation
If encephalopathy, ICU-level evaluation
Lyme carditis concern
If PR interval >= 300 ms, admit with telemetry
If second-degree Mobitz II or third-degree AV block, urgent cardiology consultation
Severe systemic illness in endemic setting
If thrombocytopenia with hemolysis pattern, urgent babesiosis evaluation
If high fever with leukopenia, urgent anaplasmosis or ehrlichiosis evaluation
Key concepts
Clinical framework
Tick-borne illness spectrum
Borrelia burgdorferi infection with staged manifestations
Common coinfections in Ixodes exposure
High-value diagnostic pivot
Erythema migrans with compatible exposure is a clinical diagnosis
Two-tier serology has low sensitivity in early localized disease
Time dependence
Tick attachment duration correlates with transmission risk
Early therapy reduces dissemination and late sequelae
