Abstract:
Objective To investigate the safety and the effectiveness of domestic harmonic scalpel in open general surgical operation.
Methods Sixty patients who underwent open surgery from Sep. 2008 to Feb. 2010 were randomly divided into test group (30 cases) and control group (30 cases). The patients in test group underwent surgery with the aid of domestic BBT harmonic scalpel, and patients in control group with Ultracision harmonic scalpel. The time of dissecting tissues, coagulation time of vessels, blood loss during operation, hospitalization time after operation and postoperative drainage volume in both groups were compared.
Results The blood loss had no distinct difference between the two groups[(89.50±27.65)ml vs (95.23±22.95)ml, P=0.298], neither did the hospitalization time [(17.3±8.8)d vs (16.1±9.9)d, P=0.604] and drainage volume [(180.6±61.0)ml vs (174.9±44.4)ml, P=0.674]. However the time of dissecting tissues in test group was longer than that in control group [(6.95±1.41)s vs (4.32±1.11)s, P<0.05], and the coagulation time in test group was also longer than that in control group[(6.00±0.314)s vs (2.68±0.123)s, P<0.001].
Conclusion Domestic BBT harmonic scalpel is safe and effective. It can meet the clinical requirements and surely will be promoted in clinical application.
