Experimental Study And Clinical Application On Monitor Of Microcirculation Of Pedical Skin Flaps And Early Division Of Their Pedicles

In spite of the methods for monitoring cutaneous microcirculation in flaps are numerous, few have been developed that provide continuous, noninvasive, and insantaneous monitoring of dermal blood flow. Laser Doppler Flowmetry ( LDF ) has been used to measure tissue surface microcirculation sine 80 era. Its major advantages are nonin-vasive, continuous, acurate and reliable, repeatable, and instanta-nous monitoring of dermal blood flow . In our expermental study, 30 random skin flaps were formed in pigs, and the skin capillary blood flow was measured with LDF ( PERIFLUX PF3 Perimed KB, Stockholm, Sweden ) pre-, and postoperatively and within 48 hours after pedicle division. The results showed that the change in the microcirculation can be divided into three phases: (1) Rapid rising (the first 3 postoprative days), (2) Plateau (3-5 postoperative days), and (3) Slow rising (after 5 postoperative days). The plateau stage may be...
