Tracheal intubation in a patient with undetectable tracheal narrowing on chest radiography.

We report here a 59-year-old man with a saber-sheath tracheal narrowing who was scheduled to undergo pharyngeal tumor resection under general anesthesia. The tracheal narrowing was not clearly detected by chest radiography during the preoperative examination, but it was visible on axial computed tomography (CT) images taken earlier for diagnostic purposes. Following fiber optic examination of the narrowed segment with the patient under anesthesia, the tube was inserted into the trachea using an Airway Scope.

[The effect of PDEIII inhibitors and colforsin daropate on hypoxic pulmonary vasoconstriction in rabbit lungs].

Background: PDEIII inhibitors and colforsin daropate hydrochloride (CDH) exert positive inotropic and vasodilatory effects by increasing intracellular cAMP The effect of olprinone (OLP), milrinone (MIL) and CDH on hypoxic pulmonary vasoconstriction (HPV) was evaluated using isolated blood-perfused lung preparations from the rabbit in situ.

Methods: We prepared a rabbit constant-flow lung-perfusion model in which HPV was induced by decreasing the FI(O2) from 21% to 3%. We conducted 2 sets of experiments by administering different doses of OLP MIL or CDH into the reservoir.

Anesthetic management for the minimally invasive Nuss procedure in 21 patients with pectus excavatum.

The aim of this study was to assess the anesthetic management and postoperative analgesic effect of continuous epidural infusion for the minimally invasive Nuss procedure. A total of 21 operated cases were analyzed retrospectively. Thoracoscopy was used in all cases.
