Cocaine
Considerations
-
Emergency/full stomach
-
Uncooperative/co-ingestions/agitated
-
Multisytem effects:
-
Airway: nasal septal necrosis
-
CNS: CVA/ICH, seizure, agitation, uncooperative, ↑MAC
-
Cardiovascular:
-
HTN, tachycardia
-
Arrhythmias
-
Coronary vasospasm resulting in angina or MI
-
Cardiomyopathy
-
Aortic dissection
-
Unopposed alpha with beta blockade
-
-
Respiratory:
-
RLD: crack lung, aspiration
-
Pneumothorax, pneumomediastinum
-
Bronchospasm
-
-
Hematologic: DIC, thrombocytopenia
-
Renal: renal infarction, rhabdomyolysis
-
GI: ischemia, ulceration, perforation
-
Conflicts
-
Difficult airway in an uncooperative patient
-
RSI in a patient with hemodynamic instability
-
Regional anesthesia in an uncooperative patient or coagulopathy
-
Placental abruption, uncooperative OB patient, difficult airway
Anesthetic Management
-
Delay OR if possible to optimize & allow for effects of cocaine to wane
-
Monitor in high acuity setting/ICU
-
Full CAS monitors, 5 lead ECG & arterial line
-
Treat adrenergic crisis & uncooperative status with benzodiazepines as first line
-
Chest pain management:
-
Consult cardiology urgently & keep broad ddx
-
Start with midazolam
-
Consider NTG & phentolamine (1-2.5 mg q 5-15 minutes)
-
Avoid beta blockers
-
-
If need for urgent GA:
-
Pre-induction arterial line
-
Treat adrenergic tone as above
-
Deep titrated GA, avoid ketamine, accept aspiration risk
-
-
Wide complex tachycardia: NaHCO3 1-2 meq/kg until hemodynamic stability & QRS <120 ms
-
Postoperative discharge to high acuity/ICU
