central anticholinergic syndrome due to hypoxia-induced bradycardia in a child with difficult intubation undergoing complete dental restoration: a case report.

central anticholinergic syndrome (cas) following general anesthesia (ga) is a well known syndrome in children and adults. many cases of cas have been previously reported in the literature. however, there are only two reports of post resuscitation cas after administration of small doses of atropine. hereby, we report a case of cas in a child undergoing complete dental restoration under ga after receiving a small dose of atropine to reverse hypoxia induced bradycardia. intraoperative events such as hypoxia or cardiac arrest may play a role as triggers for cas. however, we cannot establish a causal relationship between the occurrence of cas and such critical events.
