[Three cases of ATP-induced bronchospasm during thoracic endovascular aortic repair].

We report three cases (73-year-old, 69-year-old and 76-year-old men) of bronchospasm induced by adenosine triphosphate (ATP) during thoracic endovascular aortic repair (TEVAR). Severe broncospasm occurred soon after administration of ATP to obtain transient asystole during TEVAR. All three cases were complicated with asthma or chronic obstructive pulmonary disease (COPD) before TEVAR, and airway hyper-reactivity was suspected.

Effect of divided supplementation of remifentanil on seizure duration and hemodynamic responses during electroconvulsive therapy under propofol anesthesia.

Purpose: Although a reduced dose of propofol combined with remifentanil is often used in anesthesia for electroconvulsive therapy (ECT), there have been few studies in which the optimal technique for injection of remifentanil was examined in detail. The aim of this study was to evaluate the effects of single and divided injection of remifentanil combined with propofol on seizure duration and hemodynamic responses during ECT.

Methods: Twenty-six ASA I-II patients were enrolled in this study and received a total of 78 ECTs.

Efficacy of the Airtraq(®) laryngoscope with a fiberoptic bronchoscope compared with that of Airtraq(®) alone for tracheal intubation: a manikin study.

Purpose: Successful intubation using the Airtraq(®) requires optimal positioning of the glottis in the middle of the viewfinder. If the glottic view cannot be optimized, some glottic manipulation is essential for the Airtraq-assisted successful intubation. We evaluated the efficacy of the combined use of the Airtraq and a fiberoptic bronchoscope (FOB) compared with that of the Airtraq alone for tracheal intubation in simulated airway scenarios.

[Case of laryngeal edema occurring after tracheal extubation presumably due to antihypertensive medications].

A 61-year-old woman underwent microlaryngeal surgery for a vocal cord polyp. Anesthesia was induced with propofol, and vecuronium was given after loss of consciousness. The trachea was intubated smoothly with a Portex tracheal tube with a 6.

A comparison of the failure times of pulse oximeters during blood pressure cuff-induced hypoperfusion in volunteers.

Important information may not be obtained if the pulse oximetry signal is lost during inflation of a cuff for blood pressure measurement, particularly in patients with hemodynamic instability. In the present study, we compared the failure times of pulse oximeters during cuff-induced hypoperfusion in volunteers. A pulse oximeter sensor was attached to the index finger, and a blood pressure cuff was attached to the same arm of each volunteer.
