Psychological preparation and postoperative outcomes for adults undergoing surgery under general anaesthesia.

Background: In a review and meta-analysis conducted in 1993, psychological preparation was found to be beneficial for a range of outcome variables including pain, behavioural recovery, length of stay and negative affect. Since this review, more detailed bibliographic searching has become possible, additional studies testing psychological preparation for surgery have been completed and hospital procedures have changed. The present review examines whether psychological preparation (procedural information, sensory information, cognitive intervention, relaxation, hypnosis and emotion-focused intervention) has impact on the outcomes of postoperative pain, behavioural recovery, length of stay and negative affect.

The effect of a pre-operative infusion of Ringer's solution on splanchnic perfusion in patients undergoing coronary artery bypass grafting.

Surgical patients develop a fluid deficit during pre-operative starvation. This study examines the effects of pre-operative fluid administration on haemodynamic variables, oxygenation and splanchnic perfusion in patients undergoing elective coronary artery bypass grafting. Forty-eight patients were randomised to receive either a pre-operative crystalloid infusion (crystalloid group, n = 24) or no infusion (control group, n = 24).
