摘要
比较聚甲哌酮和聚二恶烷酮系在常用体外活结上的拉伸强度。用张力计测试了7种体外滑动结和平方结的抗拉强度。用2/0聚甲萘酮和聚二恶烷酮按随机顺序打结。该研究旨在证明在80%的功率下，结强度有5牛顿的差异，95%的置信度。在实验的每条手臂上研究了五个结。一个实验室实验。使绳结打散或使绳结打散所需的力。用聚二恶烷酮打结的结的抗拉强度为2.3 N (95% CI 0.1-0.75 N, P = 0.0332)。聚甲氨酮和聚二恶烷酮中，Tayside、Blood、Hutchon和Western结的抗拉强度均低于平方结。改良的罗德结在聚甲氨酮中比其他结更牢固，在聚二氧甲酮中比西方结和泰赛结更安全。用聚甲氨酮打结的打结强度略低于用聚二氧环酮打结的打结强度。无体外系结滑脱结比改良的罗德结更牢固。
Tensile strengths of extracorporeal slip knots tied with poliglecaprone and polydioxanone
To compare the tensile strengths of commonly used extracorporeal slipknots when tied with poliglecaprone and polydioxanone.
The tensile strength of seven extracorporeal slip knots and the flat square knot were tested using a tensiometer. Knots were tied in random order with 2/0 poliglecaprone and polydioxanone. The study was designed to demonstrate a 5-newton difference in knot strength with 95% confidence at 80% power. Five knots were studied in each arm of the experiment.
A laboratory experiment.
Force required to break or cause slippage of knots.
Knots tied with polydioxanone had a marginal yet significantly stronger tensile strength of 2.3 N (95% CI 0.1–0.75 N, P = 0.0332). The Tayside, Blood, Hutchon and Western knots had lower tensile strengths than the flat square knot in both poliglecaprone and polydioxanone. The modified Roeder knot was also stronger than the other ligatures when tied in poliglecaprone and more secure than the Western and Tayside knots when tied in polydioxanone.
Slip knots tied in poliglecaprone are marginally less strong than those tied in polydioxanone. No extracorporeally tied slip knot is stronger than the modified Roeder knot.
