Abstract:
Objective To contrastively study the effects of NERC-300 high frequency welding device and ultrasonic scalpel in rat partial hepatectomy.Methods Forty-eight rats were divided into the experimental group and control group(n=24).The experimental group applied NERC-300 high frequency welding instrument for conducting partial hepatectomy,while the control group used ultrasonic scalpel.The survival rate,operation time,bleeding volume,working temperature,extent of hepatic thermal damage and change of liver function on 1,3,7 d were compared between the two groups.Results The liver function recovery on 3 d in the experimental group was superior to the control group (P＜0.05).The intra-operative working temperature in the experimental group was lower than that in the control group(P＜0.05).The thermal damage range in the experimental group was lower than that in the control group(P＜0.05).The survival rate,operation time,bleeding volume and liver function change on 1,7 d had no statistical differences between the two groups(P＞0.05).Conclusion NERC-300 high frequency welding device is safe and effective for partial hepatectomy in rat.
