Randomized Controlled Trial Clinical Trial
The effect of an intermediate dose of labetalol on heart rate and blood pressure responses to laryngoscopy and intubation.
To evaluate the efficacy of an intermediate dose of labetalol (0.4 mg/kg) for attenuation of heart rate (HR) and blood pressure (BP) responses to laryngoscopy and intubation. ⋯ An intermediate dose of labetalol blunted the HR response to laryngoscopy and intubation during rapid-sequence induction in healthy patients but had a minimal effect on BP.

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 After the tracheal tube is withdrawn over the jet stylet, the hollow catheter can be used for jet ventilation or as an intratracheal stylet for reintubation with a new tracheal tube.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.

Comparative StudyEsophageal electrodes allow precise assessment of cardiac output by bioimpedance.
To analyze the impact of the position of the thoracic external electrodes on the values of cardiac output measured by electrical bioimpedance and to compare the results obtained by bioimpedance with those values determined by thermodilution in critically ill patients. ⋯ a) The values of cardiac output derived from measurements obtained by bioimpedance using internal electrodes were comparable with those values derived from thermodilution. b) Values of cardiac output from bioimpedance studies with external electrodes were dependent on the position of the xiphoid electrodes.
