Lobo-Machín et al. have recently published a rare complication of intoxication treatment: charcoal peritonitis secondary to a juxtapyloric perforation by a nasogastric tube.1 This type of perforations is more associated with iatrogenesis caused by the insertion of the tube than the charcoal itself and, occasionally previous gastric surgery is a risk factor.2
Gastric lavage to treat intoxications is currently discredited3–6 and is no longer a routine procedure. It is only considered as an option after recent ingestions of lethal doses and, particularly, when the toxin is not absorbable by activated charcoal.
Gastrointestinal perforation during oral administration of charcoal has never been reported, although several other complications have been described.7 In the case they present, a single oral dose of charcoal would have been sufficient for a moderate ingestion of escitalopram because it is considered that the ingestion of this drug induces ECG alterations at dose of more than 300mg.8 The additional ingestion of 3mg of bromazepam and 6mg of lormetazepam should be considered a practically atoxic dose. If the time transpired from the ingestion of these drugs until medical care was received had been more than 2h, the best option would have been not to perform any type of gastrointestinal decontamination method.9
