[Landmark method and ultrasound-guided method of internal jugular vein puncture: comparison of residents with staffs].

Background: We compared landmark with ultrasound-guided methods of internal jugular vein puncture in residents and staffs.

Methods: Seven residents and five staffs practiced internal jugular vein puncture with landmark and ultrasound-guided methods on a manikin for internal jugular vein cannulation. Thereafter, they performed internal jugular vein cannulation on 42 patients.

[Training of internal jugular vein cannulation: comparison of landmark method with ultrasound-guided method].

We compared training of internal jugular vein cannulation with ultrasound-guided method and that with landmark method in a group of 10 residents and that of 10 staffs. Cannulation was increasingly successful with both methods as the training proceeded, and with increasingly less time and fewer number of punctures. There was no statistically significant difference in time or in number of punctures with ultrasound-guided method between the groups.

[Pulmonary edema due to upper airway obstruction after extubation].

We report a patient who developed pulmonary edema due to airway obstruction after extubation. A 22-year-old man underwent removal of the nails for thoracoplasty under general anesthesia combined with epidural anesthesia. Upper airway obstruction occurred after extubation.
