The tracheal stent is an alternative nonsurgical management tool for patients with tracheal stenosis caused by disease or iatrogenic trauma. Some patients with tracheal stent may need to be anesthetized to allow invasive techniques or surgery to be performed. In these patients, general anesthesia by endotracheal intubation may dislodge the stent distally or cause lethal complications such as bleeding. We describe three patients with a tracheal stent in place, who were anesthetized using a Laryngeal Mask Airway for surgery, with smooth results.

Intense vagal discharge often follows stimulus application during electroconvulsive therapy (ECT). Related periods of asystole during ECT have been reported sporadically in psychiatric journals, but to date not in the anesthesia literature. ⋯ With these data, we discuss why asystole is likely to result from a direct central pathway rather than via a baroreceptor reflex, and discuss a neuroanatomic pathway potentially responsible for our findings. We also demonstrate that high-dose atropine (0.8 mg) can effectively prevent most cases of asystole in susceptible patients, and that administration of esmolol following cessation of seizures effectively reduces the elevated heart rate without causing asystole or bradycardia.

A 51-year-old ASA physical status II, non-insulin-dependent diabetic male patient manifested lower limb nerve injury after receiving postoperative epidural analgesia with ropivacaine 0.2%. The case is presented, including a discussion of the relation between local anesthetic toxicity and diabetic neuropathy.
