Blood loss up to 10-15% of the total blood volume can be substituted by mere crystalloids. A quicker and more stable volume replacement can be accomplished with colloid solutions. Combination of artificial colloids (e.g., dextran 60, dextran 70 or hydroxyethyl starches with high degree of hydroxyethylation) with crystalloids (isotonic balanced solutions) produces a long lasting volume effect. Due to dose limitation recommendations for the artificial colloids, volume substitution may be continued, at a later stage, by albumin.

ReviewSedation by the use of inhalation agents in dental care.
Nitrous oxide/oxygen has long been the mixture of gases used in dental practice to produce light sedation. The main indication for use of nitrous oxide/oxygen sedation is fear-anxiety. The equipment used is a continuous flow machine with a fail safe system set at a minimum of 30 or 40 per cent oxygen. ⋯ Side effects, e.g. restlessness, vomiting, and nausea are infrequent. About 90 per cent patients, who have difficulty in co-operating during dental treatment, mainly because of anxiety, show excellent or fair co-operation during nitrous oxide/oxygen sedation. Occupational exposure to nitrous oxide can be minimized by the use of scavenging systems, local exhaust systems, careful sedation technique, and equipment management.

ReviewImmunosuppressive effects of blood transfusion in anaesthesia and surgery.
The immunosuppressive effects of blood transfusion at surgical operations become manifest as enhanced graft survival, increased cancer recurrence and decreased patient survival, and increased susceptibility to postoperative infections. Blood transfusion in transplant recipients no longer offers this advantage when cyclosporine A is used. ⋯ Leucocyte-free red blood concentrates are the least immunosuppressive homologous blood preparations. Conventional red blood cell concentrates may also be used in cancer patients until ongoing prospective randomized studies confirm that there is a true association between the use of homologous blood and increased recurrence of cancer.
