Objective: Tonsillectomy is otorhinolaryngology one of the most common surgeries, since the 1970s, has been found in laser, freezing, RF, ultrasonic, electric knives and other equipment lines tonsillectomy methods have their advantages and disadvantages. Although tonsillectomy methods varied, but the duration of surgery, intraoperative and postoperative bleeding, postoperative pain has been one of the major concerns of surgery, this study focuses on tonsillectomy in children, the use of electric squeeze cutter (a novel surgical instrument tonsil) whether the cutter relative to conventional extrusion advantages. Methods: From April 2009 to March 2011 in the Second Affiliated Hospital of Dalian Medical University Hospital Department of Otolaryngology and tonsillectomy in pediatric patients met the inclusion criteria of 49 patients, aged 2.5 to 14 years, including 33 males, 16 females. Principles of randomized 49 patients were divided into experimental and control groups. The experimental group of 28 cases, including 19 males and 9 females, with a median age of 4.9 years, the use of electric squeeze knife tonsillectomy; control group of 21 cases, including 14 males and 7 females, median age of 5.1 years, using conventional extrusion cutter tonsillectomy. All patients preoperative blood routine examination, routine blood clotting, viral markers, liver function, kidney function, electrocardiogram, chest X-ray, except for surgical contraindications. Experimental group and the control group of children with tonsil surgery by the same surgeon (experienced, skillful surgery) is completed. Observe and record the two groups of children on both sides need tonsillectomy surgery duration, blood loss, postoperative wound and the degree of response of four postoperative bleeding index. Applications SPASS 17.0 software on the experimental data were used two independent samples t-test and Pearson chi-square test was used for statistical analysis. Results: 1. Operation lasted experimental group was (3.15 ± 1.30) min, the operation lasted control group (15.30 ± 2.03) min, statistical analysis of t = 25.483, P = 0.000, the experimental group was significantly less than the control group, the operation lasted , a statistically significant difference. Two experimental group blood loss (2.54 ± 2.43) ml, while the control group blood loss was (7.98 ± 3.07) ml, statistical analysis of t = 26.924, P = 0.000, the experimental group than the control group blood loss significantly less, the difference was statistically significant. Three experimental group after the first day and three days the extent of the wound reactions are mainly mild, moderate-based control group, there was no postoperative wound showed severe responders. Postoperative day 1 wounds statistical analysis of the extent of reaction χ ~ 2 = 3.960, P = 0.047, the degree of response wounds experimental group than in control group, the difference was statistically significant; wounds after the first three days the degree of response statistics Analysis results χ ~ 2 = 12.599, P = 0.000, the experimental group the degree of response wounds significantly lighter than the control group, the difference was statistically significant. 4 experimental group and the control group had no postoperative rebleeding. Conclusions: The use of electric squeeze knife tonsillectomy has the following advantages: 1. Surgery quickly, tonsillectomy and hemostasis synchronization is complete is its biggest advantage. (2) less bleeding does not even bleeding. 3. The surgical tissue damage, postoperative local reaction to light, quick recovery. 4 simple operation, easy to learn.
