Randomized Controlled Trial Comparative Study Clinical Trial
Efficacy of ultrasound-guided axillary brachial plexus block: a comparative study with nerve stimulator-guided method.
The aim of this study was to compare the efficacy of axillary brachial plexus block using an ultrasound-guided method with the nerve stimulator-guided method. We also compared the efficacy of ultrasound-guided single-injection with those of double-injection for the quality of the block. ⋯ Ultrasound-guided axillary brachial plexus block, using either single- or double-injection technique, provided excellent sensory and motor blockades with fewer adverse events.

Totally implantable venous devices (TIVDs) are used increasingly in patients with cancers and other debilitating diseases requiring long-term chemotherapy, total parental nutrition, and fluid replacement. The TIVDs are surgically inserted and fixed in the soft tissues of the chest wall to prevent infection and accidental dislodgment. ⋯ Catheter fracture and cardiac migration is a rare complication and most reported cases have developed between the clavicle and the first rib as a consequence of a pinch-off sign. We present two patients with metastatic colon cancers with unusual catheter fracture site and migration and discuss the clinical implications.
