Abstract:

Objective: To discuss the differences between the applications of continuous douche combined with vacuum sealing
drainage（VSD）and traditional open wound and indwelling drainage to treat the patients whose limbs are penetratingly wounded by the
blades of rotary cultivators, covering the aspects of inflection rates, patients' pains, the length of stay in hospital and the hospitalization
expanses. Methods: 52 cases in which the patients' arm or leg was perforated by the blades of rotary cultivators were chosen. Among
them, 25 cases were conducted by the way of traditional open wound and indwelling drainage as A group. Rest 27 cases were treated by
the way of continuous douche combined with VSD as B group. Results: The patients in B group had lower inflection rates than A group
（P<0.05）. The VAS score of B group staying in hospital after the operation was lower than that of A group（P<0.05）. The length of stay
in hospital of B group was shorter than that of A group（P<0.05）. There was no obvious difference at hospitalization costs between A
group and B group（P>0.05）. Conclusion: The therapeutic methods of A group and B group had gained a good result, the patients all
had recovered. There was no obvious difference in the hospitalization costs, but B group was better than A group at the aspects of lower
inflection rates, less patients' pains and shorter length of staying in hospital.
