Randomized Controlled Trial
The effect of stellate ganglion block on the function of arteriovenous fistulas for hemodialysis: A randomized trial.
The best access for hemodialysis is an autologous arteriovenous fistula (AVF). The most helpful way for vasodilation in the upper limb is stellate ganglion block. We aim to evaluate the effect of stellate ganglion block on outcome of vascular access for dialysis. ⋯ Stellate ganglion block before arteriovenous fistula surgery in the upper limbs improves hemodialysis success rate.

Randomized Controlled Trial Multicenter Study
Multicentre, randomised, blinded, control trial of drug-eluting balloon vs Sham in recurrent native dialysis fistula stenoses.
Endovascular treatment of autogenous arteriovenous haemodialysis fistula stenosis has high reintervention rates. We investigate the effect of drug-eluting balloons in the treatment of recurrent haemodialysis fistula stenosis. ⋯ Paclitaxel drug-eluting balloon significantly delays restenosis after angioplasty for recurrent autogenous arteriovenous haemodialysis fistula stenosis, persisting to 12 months. Drug-eluting balloon significantly increases freedom from reintervention at 12 months with these effects true in stented and unstented fistulas.

Randomized Controlled Trial Comparative Study
Ultrasound-guided radial artery catheterisation increases the success rate among anaesthesiology residents: a randomised study.
The palpation technique is generally used for radial artery catheterisation, but is associated with a high rate of failure and complications. Dynamic needle tip positioning (DNTP) is a new ultrasound-guided technique. We aimed to compare the traditional palpation technique with DNTP performed by four anaesthesiology residents. ⋯ Ultrasound-guided arterial catheterisation using the DNTP technique is superior to the standard palpation technique. This study favours the ultrasound-guided DNTP technique as the first choice rather than merely being viewed as a rescue procedure.

Randomized Controlled Trial
Tegaderm™ CHG dressing significantly improves catheter-related infection rate in hemodialysis patients.
Catheter-related infections are an important clinical problem in maintenance hemodialysis patients. Catheter-related bloodstream infections have a negative effect on survival, hospitalization and cost of care. Tegaderm™ chlorhexidine gluconate (CHG) dressing may be useful to reduce catheter-related infection rates. ⋯ This is the first prospective study to show that Tegaderm™ CHG dressing significantly reduces catheter-related infection rates in hemodialysis patients.

Randomized Controlled Trial Comparative Study
Factors associated with pain during vascular access intervention therapy.
The objective of this study is to investigate and compare factors associated with pain during vascular access intervention therapy. ⋯ The reason for severe pain with use of the semi-compliant balloon as compared with the other types might have been due to its characteristics during inflation, as increased diameter leads to an increase in pressure. Mismatching of balloon diameter to vascular diameter may also increase pain.
