RESUMO
Objective To evaluate the clinical efficacy of ultrasonic-harmonic scalpel in open thyroid surgery.Methods Totally 70 patients with thyroid surgery from January 2012 to January 2014 in some hospital were selected as the study objects, who were divided into a control group and an observation group equally. The patients in the control group went through traditional surgery, and the ones in the observation group underwent open thyroid surgery. Then the operative time, blood loss, postoperative hospital stay before and after surgery and body stress-related serum markers of two groups were analyzed and compared.Results The observation group had the operative time, blood loss and postoperative hospital stay significantly better than those of the control group, and the body stress-related serum markers 5 days after operation significantly lower than that of the control group, with P<0.05.Conclusion The short-term clinical effect of ultrasonic-harmonic scalpel in open thyroid surgery is significantly better than that of traditional surgery, which has high safety and lower degree of adverse physical stress.
