Promoting the wound healing process is a primary concern for many health care practitioners. It can take 1-3 days for a closed wound to actually establish a seal. Infections usually occur in 3-6 days but may not appear for up to 30 days.
Restoration of integrity to injured tissues by replacing dead tissue with viable tissue starts immediately after an injury, may continue for months or years and is essentially the same for all types of wounds.
Variations are the result of differences in location, severity of the wound, extent of injury to the tissues, age nutritional status, general health of the patient and available resources for tissue regeneration.
