71
Q

Clinical Sx of Cyanotic breatholding spells

A

brief, shrill cry, forced expiration and apnea.

  • cyanosis and LOC , -/- GTC fits, opisthotonos, and bradycardia, may be repeated within few hrs-
72
Q

Cyanotic breatholding spells Inv?

A

TESTS: (EEG) is normal.

-

73
Q

Cyanotic breatholding spells management?

A
  1. support and reassurance, be consistentand not reinforce the child’s behavior after the child recovers
  2. placing the child in bed NOT cuddle, play, or hold the child for a given period of time until recovery is complete
