All of the textbooks of anesthesia have recently stated that
   succinylcholine is contraindicated for routine using in children and youth
   except for emergency tracheal intubation or in instance where immediate
   securing of the airway in necessary.  This study is a rare one about the
   dangerous response of a 16 years old boy to succinylcholine in hernia
   repair. The patient got to an unstable hemodynamic condition after
   repeated dose of drug in operation room and after many hours he woke
   with severe weakness muscle tone .

          In investigation about his problem the cause of muscle lysis was
   hyperkalemia(k=6.3 mEq/L) . Myglobinuria CPK=225000 U/L , LDH= 3000
   U/L were remarkable about his problem. Finally the patient discharged in
   good condition with an unknown  myopathy diagnosis.
