When considering the postoperative care of surgical patients, there are three time periods that are important for both the patient's wellbeing and the planning of nursing care. These are termed the immediate recovery period, the intermediate stage of dependency, and the more long-term process of returning to normality. This article concentrates on the first of these stages.
Health-care providers and purchasers have been concerned with developing methods to assure the quality of the service provided in clinical contexts. Crucial to this is the integration of multidisciplinary clinical audit techniques which facilitate good practice.

Nonlinear dynamics, a branch of the basic sciences that studies complex physical systems, offers novel approaches to long-standing problems of physiological form and function. The nonlinear concept of fractals, introduced and developed over the last decade, provides insights into the organization of complex structures such as the tracheobronchial tree and heart, as well as into the dynamics of healthy physiological variability. Alterations in fractal scaling may underlie a number of pathophysiological disturbances, including sudden cardiac death syndromes.
