[Prolonged paralysis after long-term administration of vecuronium in the intensive care unit].

A 51-year-old woman with renal failure requring hemodialysis received a total of 446 mg of vecuronium over a period of 4 days to help mechanical ventilation and developed generalized muscle weakness after its discontinuation. It took 2 wks to wean her from mechanical ventilation and 3 wks for her to be able to walk.

[Successful resuscitation of intractable hyperkalemic cardiac arrest].

We report on a 42-year-old oliguric uremic man on regular hemodialysis who developed sudden cardiac arrest, secondary to severe hyperkalemia, with a plasma potassium concentration of 9.7 mEq x l(-1). The cardiac arrest persisted after the initiation of cardiopulmonary resuscitation and intensive treatment for marked hyperkalemia for an hour and 55 minutes.
