Our purpose was to evaluate the use of the Harmonic scalpel in neck dissections.
We conducted a randomized prospective intervention study to compare the Harmonic scalpel (32 patients) with the conventional technique (31 patients).
Operative time was lowered by 64 min (p < 0.001) and 7.5 min (p = 0.367); blood lost during surgery was lowered by 80.5 ml (p < 0.001) and 76.6 ml (p < 0.001); the length of time the drains were kept in place was lowered by 1.3 days (p < 0.001) and 1.5 days (p < 0.01); and the volume of drainage was lower by 228.7 ml (p < 0.001) and 187.6 ml (p < 0.01) in selective and comprehensive neck dissections respectively in patients treated with the Harmonic scalpel.
The Harmonic scalpel shortens operative time in selective dissections. It reduces blood loss during surgery; time drains are kept in place and the amount of drainage in comprehensive and selective neck dissections.
评估超声刀在颈部解剖中的应用。
我们进行了一项随机前瞻性干预研究，比较了超声刀（32 例）与传统技术（31 例）。
手术时间缩短 64 分钟（p<0.001）和 7.5 分钟（p=0.367）；术中失血量减少 80.5ml（p<0.001）和 76.6ml（p<0.001）；引流管留置时间缩短 1.3 天（p<0.001）和 1.5 天（p<0.01）；引流体积减少 228.7ml（p<0.001）和 187.6ml（p<0.01），分别为选择性和综合性颈部解剖中接受超声刀治疗的患者。
超声刀缩短了选择性解剖的手术时间。它减少了术中失血；保留引流管的时间和全面、选择性颈部解剖中的引流量。
