title: Risk factors for surgical infection.
abstract: In the last century remarkable advances have been made in surgery, associated with the lowest recorded rates of infection or sepsis. Many surgical practices are time honoured but have little scientific basis to prevent postoperative infection whereas some local and systemic factors are well recognized and can be modified to lower infection risks. Surgical skill is not easily measurable but shorter operations in experienced hands leaving the minimum of tissue damage, haematoma or dead space have the lowest infection rates in general surgery: < 2% in clean and < 10% in contaminated operations. Adequate surgical scrub, appropriate suture materials and antibiotic prophylaxis, perioperative correction of dehydration and poor nutrition are examples of effective therapy which can be conformed to by all surgeons. Other factors, such as the use of wound guards, drains and surgical dressings are less easy to estimate for effectiveness or be sure that they could be changed or left out of surgical ritual.
