This type of exudate has justifiably been termed ‘a wounding agent in its own right’ because it has the capacity to degrade growth factors and peri-wound skin and predispose to inflammation .In order to develop an effective management approach, the clinician must be able to accurately assess and understand the implications of the composition and quantity of exudate present in the wound.In chronic wounds, the colour, consistency and amount of exudate may change as a result of various physiological processes  See Table 2. Some strains of Staphylococcus aureus, β-haemolytic group A streptococci and Bacteroides fragilis, produce fibrinolysins. This has been attributed in part to specific bacterial virulence mechanisms that result in vasodilation and extravasation .Pseudomonas aeruginosa produces a non-specific enzyme that degrades fibrin. Gautam et al (2001)  have described a process whereby neutrophils attracted to the site of injury trigger the release of heparin-binding protein (HBP).However, when the wound becomes ‘chronic’ and non-healing with persistent, abnormal inflammation or when infection becomes established, exudate takes on a different guise and generates clinical challenges.In the chronic wound, exudate contains proteolytic enzymes and other components not seen in acute wounds .Richard White Ph D Senior Research Fellow, Tissue Viability Grampian NHS Trust, Aberdeen, Scotland, UK.

In the first 48 to 72 hours after wounding, platelets and fibrin may be present, but this reduces as bleeding diminishes. As fluid passes through the inflamed vessel walls (extravasation) it may be seen that wound exudate is in essence modified serum and will therefore contain similar solutes.Inspection of a dressing on removal may yield valuable information on the level of exudate produced during dressing wear time.To assess the exudate volume the healthcare practitioner should count the number of dressings used over a time period, note the wear time for individual dressings, examine the dressing for the presence of strikethrough (wet or dry), examine the peri-wound skin condition and note any leakage .The volume of exudate may be described using the terms shown in Table 3 . The Pressure Sore Status Tool a few thousand assessments later.Adv Wound Care 1997; 10(5): 65-73 .] Accurate assessment of the volume and viscosity of exudate will indicate whether or not healing is progressing normally .
Exudate management is relevant to patient quality-of-life issues as it is often associated with leakage and malodour.
