(20) We conclude that calcium chloride is not of value in resuscitating patients from refractory asystole in the prehospital cardiac arrest setting.

(4) During the procedure, acute respiratory failure developed as a result of tracheal obstruction.
(5) Erythrocyte membrane choline transport is abnormally high in chronic renal failure.
(6) Four patients died while maintained on PD; three deaths were due to complications of liver failure within the first 4 months of PD and the fourth was due to empyema after 4 years of PD.
