Loco-regional anesthesia, along with the neurosensitive inhibition causes arterial and venous vasodilatation, that could be of interest for vascular access surgery. We evaluated the long term vasoplegia persistence after brachial plexic block. ⋯ The vasoplegia accompaning plexic block lasted 6 hours after anesthesia induction. Whereas this longstanding haemodynamic effect is beneficial for early patency of vascular access for hemodialysis, needs to be ascertained by further investigations.

To identify clinically important risk factors associated with upper extremity venous thrombosis following peripherally inserted central venous catheters (PICC). ⋯ In multivariate analysis, trauma, renal failure, left-sided catheters, basilic placement, TPN, and infusion with antibiotics, specifically vancomycin, were significant risk factors for UEVT associated with PICC insertion. Prophylaxis with low molecular weight heparin, unfractionated heparin or use of warfarin did not prevent the development of venous thrombosis in patients with PICCs. Length of hospital stay and cost are markedly increased in patients who develop PICC-associated upper extremity venous thrombosis.

Multicenter Study
Tunneled hemodialysis catheter-related bloodstream infections: a prospective multicenter cohort study from Spain.
Catheter-related bloodstream infections (CRBSI) are common among patients undergoing long-term hemodialysis (HD) worldwide. The aim of this study was look into the incidence, epidemiology, and risk factors for CRBSI in four medical centers and Spanish dialysis facilities following a common protocol for insertion and management of tunneled hemodialysis catheters (THCs). ⋯ Although some factors, such as vascular cause of renal disease and previous THC medical history, have been related to the onset of tunneled catheter-related bloodstream infections, the incidence of these bacteremia, mainly produced by gram-positive coccus, is low among hemodialysis patients and the mortality rate is not high.
