- Perioperative acute renal failure is a common complication of major surgery and is associated with increased morbidity and mortality.
- Ischaemia- or toxin-mediated acute tubular necrosis is the primary cause of perioperative acute renal failure.
- The key non-pharmacological strategies are intravascular volume expansion, maintenance of renal blood flow and renal perfusion pressure, avoidance of nephrotoxic agents, careful glycaemic control, and the appropriate management of post-operative complications.
- At present, there is no firm evidence to suggest that the use of any specific pharmacological intervention is clinically beneficial.
- Dopamine infusion has not been shown to prevent acute renal failure, avert the need for renal replacement therapy, or reduce mortality, and should not be administered solely for renal protection.
Clinical experience with power injectable peripherally inserted central catheters in intensive care patients Introduction In intensive care units (ICU), peripherally inserted central catheters (PICC) may be an alternative option to standard central venous catheters, particularly in patients with coagulation disorders or at high risk for infection. Some limits of PICCs (such as low flow rates) may be overcome by the use of power-injectable catheters . Method We have retrospectively reviewed all the power injectable PICCs inserted in adult and pediatric patients in the ICU during a 12-month period, focusing on the rate of complications at insertion and during maintenance. Results We have collected 89 power injectable PICCs (in adults and in children), both multiple and single lumen. All insertions were successful. There were no major complications at insertion and no episodes of catheter-related blood stream infection. Non-infective complications ...
