ReviewTechnical aspects of central venous catheterization.
Central venous access has been widely used in the treatment of different categories of patients but it is associated with a wide range of complications. Different catheters, approaches and techniques have been employed to minimize those complications related to catheter insertion as well as those related to the prolonged use of catheters. This article reviews the technical aspects of central venous catheterization and associated complications.

ReviewNutrition support in patients with multiple organ failure.
The problem with any attempt to feed patients in multiple organ failure is that, because of an ongoing inflammatory process, the conventional techniques of supplying energy and protein do not maintain lean tissue mass. In addition, the conventional markers of nutritional status, both anthropometric (body mass and composition, arm circumference, etc.) and visceral protein (albumin, prealbumin) as well as immunological markers (delayed reactive skin hypersenstivity to common antigens and lymphocyte counts) are confounded by fluid retention (5-15 l) and the metabolic response to the illness. Recent research has focussed on the nature and origin of this inflammatory response, the problems of trying to feed an individual undergoing such a response, the details of the protein breakdown observed in sepsis and multiple organ failure and methods of modifying the response favourably.

ReviewClinical efficacy of perioperative nutrition support.
Despite a large number of published randomized prospective controlled clinical trials the indications for perioperative parenteral and enteral nutrition support remain controversial. This article reviews the reports of several recently published consensus conference reports and prospective randomized controlled trials evaluating nutritional therapy in surgical patients.
