Abstract:
ObjectiveSurgical site infection (SSI)is a type of common hospital-acquired wounds. The purpose of this study is to understand its clinical characteristics and prognosis in order to provide evidence for taking appropriate measures.Methods132 wound patients who met the diagnostic criteria of surgical site infection in the wound care center in recent 3 years were enrolled. The patients were treated locally with nanosilver dressing combined with red light and infrared ray. Individualized nutritional recipes and activity prescriptions were given, and the skin was showered every other day to heal or last 2 months.Observation indicators: demographics and wound characteristics; changes of area and depth after14 days intervention; the posi-tive rate of bacteria before and after the intervention, and healing rate and healing time of 2 months were analyzed and compared.ResultsA total of 132 cases of SSI(52.27% superficial and 47.73% deep ) was identified. The average age was 48.33±16.90 years. The average age and gender of the two groups were similar (P>0.05).Peri-wound skin is contaminated in all cases. The mean onset time of SSIs was 19.82±5.64 days, and the median onset time was 20 days. The onset time and duration of deep SSIs were longer than that of superficial SSIs (P<0.05). There was no significant difference between deep and superficial SSIs in a wound area (P>0.05), and the depth of deep SSIs was deeper than that of superficial SSIs (P<0.05).The positive rate of bacterial culture inthe deep SSI group (79.31%) was higher than that of the superficial SSI group (59.46%) (P<0.05). After 14 days treatment, the area was smaller, the depth was lower (P<0.05), and the positive rate of bacteria was significantly decreased in the two groups (P<0.05). The healing rate ofsuperficial SSI group (84.06%) was higher than that of deep SSI group (66.67%) (P<0.05) in two months, and the healing time of superficial SSI group was significantly shortened (35.46<11.12 days vs 41.08<11.33 days, P<0.05). Logistic regression analysis showed that negative bacterial culture before intervention increased the healing index (OR=0.190). Long-term use of antibiotics did not promote healing (OR=0.343).ConclusionSuperficial and deep SSIs are common types of SSIs. Gender and age are similar, and skin contamination may play a role in the development of SSI,which needs attention. Local and systemic interventions can effectively improve wound healing. Negative bacterial culture and proper use of antibiotics can improve the healingprobability.
