Q

How do we treat serotonin syndrome?

A

discontinue all serotonergic agents and symptoms usually resolve in 24 hours

Supportive care to normalize vital signs

  • oxygen, IV fluids, cardiac monitoring
  • if medical treatment for tachycardia or HTN is needed, use short- acting agents (esmolol, nitroprusside)

Sedation with benzodiazepines

If T>41, sedation, paralysis, ET tube- mechanical cooling

  • paralysis should relieve the hyperthermia, which is caused by muscle activity
  • there is no benefit in using antipyretics in this scenario

If agitation despite benzodiazepine then use a serotonin inhibitor like cyproheptadine

Adter sx resolve, assess need to resume serotonergic agent
