Anaesthesia
-
The endothelial glycocalyx is an important part of the vascular barrier. The glycocalyx is intimately linked to the homoeostatic functions of the endothelium. Damage to the glycocalyx precedes vascular pathology. ⋯ In the second part, we have systematically reviewed interventions to protect or repair the glycocalyx. Glycocalyx damage can be caused by hypervolaemia and hyperglycaemia and can be prevented by maintaining a physiological concentration of plasma protein, particularly albumin. Other interventions have been investigated in animal models: these require clinical research before their introduction into medical practice.

Review
A review of echocardiography in anaesthetic and peri-operative practice. Part 1: impact and utility.
Echocardiography is migrating rapidly across speciality boundaries and clinical demand is expanding. Echocardiography shows promise for evolving applications in the peri-operative assessment and therapeutic management of patients undergoing non-cardiac surgery, whether it be elective or emergency. ⋯ The discussion around more widespread incorporation of cardiac ultrasound into anaesthetic practice must take into account competency, training and governance. Failure to do so adequately may mean that the use of echocardiography is poorly applied and costly.
