A prospective, randomized, blinded clinical trial was conducted to determine whether electrocautery as a means of creating abdominal or thoracic wounds would result in increased wound infection rates. Over a 15-month period, 492 consecutively studied patients were randomly placed into 1 of 2 groups: scalpel or electrocautery. There were no differences in age grouping, use of steroids, incidence of diabetes, number of days preoperative, operative time, use of preoperative antibiotic prophylaxis, use of drains, number of obese patients, or gender ratio. Wound infections developed in 38 of the 250 scalpel patients (15%) and in 30 of the 242 cautery patients (12%). The use of electrocautery to create surgical wounds does not increase wound infection rates.
进行了一项前瞻性、随机、双盲临床试验，以确定使用电灼术制造腹部或胸部伤口是否会导致伤口感染率增加。在15个月的时间里，492例连续研究的患者被随机分为两组：手术刀组或电灼术组。两组在年龄分组、类固醇使用情况、糖尿病发病率、术前天数、手术时间、术前抗生素预防使用情况、引流管使用情况、肥胖患者数量或性别比例方面均无差异。250例手术刀组患者中有38例（15%）发生伤口感染，242例电灼术组患者中有30例（12%）发生伤口感染。使用电灼术制造手术伤口不会增加伤口感染率。
