Transillumination of the cervical airway with the light wand for blind intubation is a valuable adjunct to anesthesiologists and emergency room physicians, particularly for management of the complicated airway in which direct visualization of the larynx is not possible. However, as an alternative to traditional methods, this technique should be practiced in simple cases before it is attempted in more difficult airway cases. ⋯ The incidence of complications remains low but complications may be serious when they occur. We present a case of cricoarytenoid subluxation after blind intubation with a lighted stylet.

In response to interest from readers the authors provide an update of their 1986 papers on coping with medical emergencies in dental practice. In particular they review drug regimes and the technique of cricothyroidostomy.

[Effects of intravenous injections of lidocaine on hemodynamics and catecholamine levels during endotracheal intubation in infants and children].
It is known that during anesthesia, administering medication and endotracheal intubation often cause stress for the patient which induces sthenia of the endocrinal system as well as changes in hemodynamics, sometimes leading to further systemic complications. Various changes in hemodynamics caused by endotracheal intubation in infants and children were studied, including tachycardia and increased blood pressure. Changes in catecholamine levels in blood plasma and in cardiovascular parameters were observed, with patients divided into two groups for comparison. ⋯ The results also indicate that systemic complications during the induction of general anesthesia may be due to an increased secretion of endogenous catecholamines. These results further suggest that an intravenous injection of lidocaine is not effective in suppressing the increase of catecholamines in the plasma during endotracheal intubation. The intravenous injection of lidocaine, however, inhibits tachycardia and also inhibits the increase in blood pressure often caused by endotracheal intubation, and also serves to reduce the general oxygen demand in the cardiac tissue.
