BACKGROUND
The aim of this study was to compare reliability in handling and function of resterilised and single-use disposable ultrasonic scissors.
METHODS
In a prospective randomized study, the surgeon blindly tested new and resterilised ultrasonic scissors. The parameters were force of activation, cutting effect, coagulation effect, error messages and disturbing generator noise.
RESULTS
51 new and 49 resterilised instruments in 94 operations were evaluated. The differences in force of activation, cutting effect and coagulation were not significant. Error messages and disturbing noises were rare in both groups. 6 new instruments and 2 resterilised instruments had to be exchanged because of problems during surgery.
CONCLUSION
This study demonstrates comparable reliability in function and handling of resterilised and new ultrasonic scissors. The use of resterilised instruments leads to distinctly reduced costs and could contribute to efficiency in laparoscopic surgery.
背景
本研究旨在比较重复消毒使用的超声剪刀与一次性使用的超声剪刀在操作和功能方面的可靠性。
方法
在一项前瞻性随机研究中，外科医生对新的和重复消毒的超声剪刀进行盲测。参数包括激活力、切割效果、凝血效果、错误信息和干扰发生器噪声。
结果
在94例手术中评估了51把新器械和49把重复消毒的器械。激活力、切割效果和凝血方面的差异不显著。两组中错误信息和干扰噪声都很少见。6把新器械和2把重复消毒的器械因手术中出现问题而不得不更换。
结论
本研究表明，重复消毒的超声剪刀与新的超声剪刀在功能和操作方面具有相当的可靠性。使用重复消毒的器械可显著降低成本，并有助于提高腹腔镜手术的效率。
