We describe preoperative sedation with oral dexmedetomidine 5 mcg/kg in an uncooperative adult with autism and developmental delay. The sedation with oral dexmedetomidine achieved good sedation level (Ramsey 4-5), allowing for calm transfer of the patient to the operating room and uneventful induction of anesthesia.

Case Reports
Iterative epidural blood patch for recurrent spontaneous intracranial hypotension during pregnancy.
A 30-year-old woman at 28 weeks presented with sudden onset of intense headache, epigastric pain, hot flushes, nausea, vomiting, and stiff neck. Cerebral magnetic resonance imaging showed pathognonomic signs of spontaneous intracranial hypotension (SIH). ⋯ SIH is a rare entity during pregnancy which may be diagnosed using magnetic resonance imaging. Iterative Epidural blood patch should be proposed to patients with SIH during pregnancy because it allowed faster symptoms improvement and patient relief with complete recovery than medical treatment only.

We report a patient with a life-threatening anaphylactic reaction to a chlorhexidine-coated central venous catheter, confirmed with a high serum level of chlorhexidine-specific IgE. To our knowledge, this is the first case successfully resuscitated using extracorporeal membrane oxygenation (ECMO). Great caution is required when using chlorhexidine and chlorhexidine-impregnated catheters, given that its widespread use has the potential to sensitize certain patients and may result in life-threatening anaphylaxis on subsequent exposure. ⋯ We have designed a flowchart for the diagnosis and management of severe anaphylaxis. This case report highlights the potential for chlorhexidine to be a source for the development of refractory anaphylactic shock. We suggest that ECMO may save the lives of patients with severe bronchospasm and refractory anaphylactic shock secondary to chlorhexidine.
