ABSTRACT
Objective To evaluate the application of microcirculation temperature regulator for patient receiving reversed digital artery island flap surgery comparing with conventional heat lamp. Methods 68 patients after reversed digital artery island flap surgery in department of foot and hand surgery were randomized to treatment group using microcirculation temperature regulator (n=34) and control group using heat lamp (n=34) by random number table. Flap survival, length of hospital stay and satisfaction were evaluated. Results 100.00%of 34 flaps survived in the treatment group, higher than 67.65%(23 flaps of 34) in the control group, statistical differences were observed between two groups (χ2=13.123,P<0.01). Average length of hospital stay in treatment group was (11.6 ± 5.9) days, shorter than (19.5 ± 8.1) days in control group (t=4.600,P<0.01). Patients satisfaction rate was 100.00% (34/34) in microcirculation temperature regulator application group, which was also higher compared to using heat lamp 76.47% (26/34) (χ2=12.851,P<0.01). Conclusions Application of microcirculation temperature regulator could increase flap survival, shorten length of hospital stay, and improve patients′satisfaction.
