The use of a cuffed endotracheal tube (ET) has been discouraged in children up to 8 years of age. Recent literature suggests that this age-old argument is empirical rather than scientifically based. This AANA Journal course will examine the history of pediatric endotracheal intubation, suggested methods for choosing the appropriately sized ET emerging literature describing the advantages and disadvantages of the use of the cuffed ET in young children, and potential clinical problems that develop with the use of the currently available, manufactured, cuffed pediatric ETs.

Review Case Reports
Methylene blue for refractory hypotension: a case report.
Methylene blue has multiple indications for use, but recently it has been shown to be useful in treating refractory hypotension. Anaphylaxis results in widespread vasodilation and hypotension. Epinephrine has been described as the drug of choice in the treatment of hypotension for anaphylaxis, but the increased heart rate may be poorly tolerated by some patients. ⋯ Furthermore, the patient required a decreased amount of vasoactive agents in the postoperative course. The suspected mechanism of action of methylene blue is inhibition of the enzyme nitric oxide synthase, which ultimately prevents the smooth muscle dilation that accompanies anaphylaxis. Methylene blue may be a valuable adjunct in the treatment of anaphylaxis and other causes of refractory hypotension.
