A jet stylet is a small internal diameter (ID), semirigid hollow catheter that is inserted into an in situ tracheal tube prior to extubation of a patient who may be difficult to reintubate. After the tracheal tube is withdrawn over the jet stylet, the hollow catheter can be used for jet ventilation or as an intratracheal stylet for reintubation with a new tracheal tube. It was previously thought that after the new tracheal tube was inserted over the jet stylet, the stylet would have to be removed to allow connection of the new tube to the breathing circuit and confirmation of intratracheal placement of the tube. We describe a method for preserving the intratracheal location of the jet stylet while confirming intratracheal placement of the new tracheal tube.

To determine how well Laser-Guard protects polyvinyl chloride (PVC) endotracheal tubes from the carbon dioxide (CO2) laser. ⋯ Laser-Guard protects the shafts of combustible PVC endotracheal tubes from direct, high-power, continuous CO2 laser radiation.

To determine the accuracy of body surface area (BSA) calculations proposed in the literature and their applicability to patient populations such as neonates and parturients. ⋯ Several BSA formulas, including the DuBois and DuBois formulas adequately predict measured BSA over a wide range of patient populations. Although the original subjects studied by Dubois and DuBois excluded extremes of height and weight, their formula appears to be a valid predictor.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparative effects of desflurane and isoflurane on vecuronium-induced neuromuscular blockade.
To evaluate the neuromuscular effects of a nondepolarizing muscle relaxant (vecuronium) during anesthesia with equipotent concentrations of either desflurane or isoflurane. ⋯ Vecuronium has similar neuromuscular effects when administered in the presence of desflurane 3% and isoflurane 0.6%.
