ABSTRACT
<p><b>OBJECTIVE</b>To investigate the possibility and the limit in increasing the survival area of the random skin flap by extremely increasing the ratio of its length and width within 24 hours.</p><p><b>METHODS</b>SD rats (n = 20) were chosen for this study. The rats were randomly divided into subject group and control one. Pre-made skin flap was prepared as design. The subject group was carried out rapid pre-fabricated skin flap formation training. No training was performed in control group. The changes in perfusion value of micro-circulation inside skin flap were monitored during the whole process, and micro-circulation parameters of the skin flap were used to evaluate whether its blood circulation network was mature or not.</p><p><b>RESULTS</b>Training of pre-made skin flap at 18th hour, the perfusion value of its micro-circulation was basically stable, Skin flap formation was finished at 24th hour. Survival area in control group was (68.25 +/- 0.18)% and in subject group was (97.25 +/- 0.24)% (P < 0.01). There was a significant difference between the two groups.</p><p><b>CONCLUSIONS</b>Within short time, it is possible to establish micro-circulation in skin flap which exceeds the limit set by traditional theory. Digitalized judgment can be used to monitor the fast formation of super-big skin flap. This method is reliable and can increase the survival rate of random skin flap.</p>
