RESUMO
Stroke is one of the most devastating complications after cardiac surgery,and contributes to both mortality and morbidity.Coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) are the common procedures for the treatment of coronary artery disease.This article reviews the pathophysiologic mechanisms,risk factors,treatment and prognosis of stroke after CABG and PCI.
RESUMO
BACKGROUND:Recombinant human epidermal growth factor has been shown to promote granulation tissue formation and to accelerate the healing of burn wounds, but the antibacterial effect of recombinant human epidermal growth factor is limited. OBJECTIVE:To investigate the effect of nano-silver dressing combined with recombinant human epidermal growth factor gel in treatment of burns and the influence on the scar. METHODS:A total of 76 cases of shal ow II and depth II degree were randomly enrol ed and assigned to two groups. In the study group, recombinant human epidermal growth factor was coated on the surface of the wound, and then covered by nano-silver dressing. In the control group, recombinant human epidermal growth factor was coated on the surface of the wound, and covered by ordinary sterile gauze. The healing time, the positive rate of bacteria, scarring and adverse reactions were compared between the two groups. RESULTS AND CONCLUSION:The wound healing time and the rate of hypertrophic scars after healing were lower in the study group than in the control group (P0.05). These data confirmed that recombinant human epidermal growth factor gel combined with nano-silver dressing in the treatment of burn has good efficacy and accelerates the wound healing, reduces scar formation, and improves aesthetics.
