Acid and alkaline diuresis. When are they of value in the treatment of poisoning?

The utility of both acid and alkaline diuresis has been brought into question because of the ability to increase the elimination rate of many toxins by less care-intensive methods such as repeated-dose charcoal. Alkaline diuresis is a technique which uses a common drug, but acid diuresis is not a technique known to most physicians. The former is currently the best therapy for quinine poisoning. Phencyclidine elimination is increased by 10%, but most patients recover with only supportive care. Acidification has been effective in some hands; data suggest that renal elimination is not the only mechanism of action of this therapy. In deeply comatose patients with hypotension, acidification should be considered. Alkalinisation, the mainstay of therapy for salicylate and phenobarbital poisoning over many decades, is effective, although no more so than charcoal, and less than dialysis.

Subacute chlordane poisoning.

A 30 year old female was exposed to chlordane through careless and excessive domestic use over a 1 to 4 week period. Early symptoms included circumoral numbness, anorexia, nausea, and fatigue. Myoclonic jerks occurred after a delay of one month. Malaise and anorexia became the dominant symptoms leading to referral at six months. Dysfunctional bleeding was attributed to hepatic enzyme induction by the chlordane and increased metabolism of contraceptive medication. Cholestyramine increased the stool elimination of chlordane.

Severe central nervous system damage and profound acidosis in persons exposed to pentaborane.

Three cases of pentaborane intoxication resulting from a common exposure are presented. These cases were characterized by the rapid onset of seizures and opisthotonic spasms accompanied by severe metabolic acidosis without respiratory compensation. Rhabdomyolysis occurred, serum transaminase levels were elevated, and liver damage was demonstrated histologically. One patient died and another sustained severe neurologic damage. These poisonings are unique with respect to the rapid and devastating neurologic consequences. Pentaborane is an extremely toxic compound and a major hazard not only to exposed workers but also to the medical personnel dealing with them.
