Comparative Study
[Safety of axillary and subclavian vein cannulation using real-time ultrasound guidance].
The safety of real-time ultrasound-guided subclavian and axillary vein cannulation as opposed to ultrasound-guided internal jugular vein cannulation has not received much attention. We retrospectively compared the safety and value of real-time ultrasound-guided cannulation in the subclavian and axillary veins with those of the landmark method. ⋯ Real-time ultrasound-guided subclavian and axillary vein cannulation is associated with a low incidence of complications similar to that of the internal jugular vein when competent individuals with appropriate training apply the technique.

A 63-year-old man with von Recklinghausen disease was transported to the emergency department for swelling and pain of his right neck. Chest X-ray and computed tomography scan showed displacement of the trachea to the left by a tumor mass. Urgent airway management was required and fiberoptic intubation in awake condition was planned. ⋯ Suddenly, his consciousness level and Sp(O2) went down, therefore surgical airway was required. Due to pre-scanning, emergency cricothyroid membrane puncture could be performed immediately without any complications. We recommend ultrasound pre-scanning for cricothyroid membrane puncture in a patient with suspected tracheal displacement.

Arrhythmogenic right ventricular cardiomyopathy is a genetic cardiomyopathy characterized by replacement of right ventricular myocardium by fibrofatty infiltrates, leading to significant ventricular arrhythmias with sudden death and right ventricular dysfunction. Elective operations should be postponed, until the arrhythmias and myocardial function are well tolerated. There has been no guideline on the anesthetic management of this serious, despite rare, disease and there are a few reports of the patients undergoing operation under either general or regional anesthesia. ⋯ It is essential to apply alpha-adrenergic agonists instead of beta-agonists for intraoperative hemodynamic support. The arrhythmias should be managed with beta-blockers or amiodarone. Adequate control of postoperative analgesia and nausea/vomiting is also important to suppress sympathetic activities.

It has been reported that multiple puncture more than or equal to 3 times is a factor associated with the development of CVC-related complications. The present retrospective study was undertaken to evaluate the predictors and risks of multiple puncture during the insertion of CVC. ⋯ The results of the study indicate that the age less than 6 years is a significant predictor for multiple puncture during the CVC insertion.

A 21-day-old female neonate weighing 3.2 kg was scheduled for surgical excision of a maxillary tumor under general anesthesia. The lesion was present since birth, with gradual enlargement since then. Preoperatively, the lesion measured 25 mm in diameter, although it was not known whether it was benign or malignant. ⋯ The surgical procedure lasted for 27 minutes and at the end of the surgery we successfully intubated the patient's trachea with a spiral tube using a guide wire and bronchofiber. After adequate blood transfusion to restore the patient's blood volume, a nasogastric tube was inserted and the patient was extubated in a fully awake state with establishment of adequate spontaneous breathing. Postoperatively, histopathologic examination revealed that the tumor was a jawbone medullary hemangioma.
