Randomized Controlled Trial Comparative Study Clinical TrialComparison of lactate and bicarbonate buffered haemofiltration fluids: use in critically ill patients.
To compare acid-base balance, lactate concentration, and haemodynamic and O2 transport variables during haemofiltration with replacement fluid containing 44.5 mmol/l Na+ lactate or 40 mmol/l Na+ HCO3- and 3 mmol/l lactic acid. ⋯ The degree of correction of acidosis during the first 24 h of haemofiltration was determined by patients outcome but was not affected by the substitution of bicarbonate- for lactate-containing replacement fluids.

Comparative StudyUltrasound-guided cannulation versus the landmark-guided technique for acute haemodialysis access.
The correct placement of large-bore venous catheters plays an important role in the management of haemodialysis patients. Whilst the procedure for landmark-based placement of these catheters is well known, the technique is not without significant morbidity and mortality. Complications include arterial puncture, haematoma, and pneumothorax. The procedure may be further complicated in these patients by venous thrombosis and abnormal vein position from multiple previous attempts at venous access. ⋯ The use of ultrasound guidance is associated with fewer complications and is more likely to lead to cannulation of the vein at the first attempt in haemodialysis patients.

Clinical Trial Controlled Clinical TrialUltrasound-guided cannulation of the femoral vein for acute haemodialysis access.
Central venous access is a mandatory part of patient management in many clinical settings and is usually achieved with a blind, external landmark-guided technique. The purpose of this study is to evaluate whether an ultrasound technique can improve on the external landmark method. ⋯ Ultrasound-guided cannulation of the femoral vein reduces the time required for the procedure, reduces the number of passes needed to puncture the vein, and minimizes complications such as arterial puncture or haematoma.
