Pediatric wound infections: a prospective multicenter study.

OBJECTIVE: Surgical wound infections remain a significant source of postoperative morbidity. This study was undertaken to determine prospectively the incidence of postoperative wound infections in children in a multi-institutional fashion and to identify the risk factors associated with the development of a wound infection in this population. SUMMARY BACKGROUND DATA: Despite a large body of literature in adults, there have been only two reports from North America concerning postoperative wound infections in children. METHODS: All infants and children undergoing operation on the pediatric surgical services of three institutions during a 17-month period were prospectively followed for 30 days after surgery for the development of a wound infection. RESULTS: A total of 846 of 1021 patients were followed for 30 days. The overall incidence of wound infection was 4.4%. Factors found to be significantly associated with a postoperative wound infection were the amount of contamination at operation (p = 0.006) and the duration of the operation (p = 0.03). Comparing children who developed a wound infection with those who did not, there were no significant differences in age, sex, American Society of Anesthesiologists (ASA) preoperative assessment score, length of preoperative hospitalization, location of operation (intensive care unit vs. operating room), presence of a coexisting disease or remote infection, or the use of perioperative antibiotics. CONCLUSIONS: Our results suggest that wound infections in children are related more to the factors at operation than to the overall physiologic status. Procedures can be performed in the intensive care unit without any increase in the incidence of wound infection.

Effect of age-related lipid peroxidation on membrane fluidity and phospholipase A2: modulation by dietary restriction.

Age-related changes in membrane property are generally accepted phenomena. In this report, using the anti-lipoperoxidative measure of dietary restriction on membranes, the age-related effects of lipid peroxidation on membrane fluidity are explored in conjunction with the membrane-associated phospholipase A2. The fluidity of mitochondrial and microsomal membranes from ad libitum fed rats shows a progressive decline with age as indicated by a substantial decrease in two parameters, l/polarization and l/anisotropy. In contrast, the membrane fluidity of dietary restricted rats shows slight changes between 6 and 24 months of age. Evidence is presented to support the possibility that age-related peroxidation of membrane lipids may play a significant role in bringing about fluidity changes in aged membranes. The findings on the increased phospholipase A2 with age is also consistent with this conclusion.
