In a prospective study of 189 colorectal operations, the subcutaneous fat layer in the abdominal incisional wound was measured for correlation with wound infection. The infection rate was 20% when the fat layer was greater than or equal to 3.5 cm and 6.8% when the thickness was less than or equal to 3 cm (statistically significant difference). This c. threefold rise indicates that in obese patients special attention should be directed to antibiotic and other prophylaxis against incisional infection.
在一项对189例结肠直肠手术的前瞻性研究中，测量了腹部切口伤口的皮下脂肪层，以研究其与伤口感染的相关性。当脂肪层大于或等于3.5厘米时，感染率为20%；当厚度小于或等于3厘米时，感染率为6.8%（统计学上有显著差异）。这种约三倍的上升表明，对于肥胖患者，应特别注意使用抗生素及采取其他预防切口感染的措施。
