Objective To explore the efficacy of enhanced recovery after surgery（ERAS） in bridging replantation of severed fingers with perforator bone flap of anterior tibial artery. Methods A total 68 patients with amputated fingers who received bridging replantation of perforator bone flap of anterior tibial artery in a hospital in Jiaozuo from January 2019 to June 2020 were randomly divided into study group and control group

with 34 cases in each group. Patients in control group were treated with routine nursing and patients in study group were treated with ERAS. The recovery of blood supply

the survival rate and the incidence of complications of amputated fingers at 7 days after operation

the effect of intervention 3 months after operation

the motor function and quality of life of severed fingers 1 year after operation were compared between the two groups. Results The capillary filling time and VAS score of amputated fingers in the study group were lower than those in the control group

and the oxygen saturation in the study group was significantly higher than that in the control group

and the difference was statistically significant（P<0.05）. The survival rate of severed fingers in the study group（89.58%

43/48） was higher than that in the control group（69.23%

36/52）

and the difference was statistically significant（χ~2=6.232

P=0.013）. The excellent and good rate of patients in the study group after treatment for 3 months was（88.24%

30/34）

which was higher than that of the control group（64.76%

31/34）

and the difference was statistically significant（χ~2=6.353

P=0.012）. One year after operation

the finger grip strength index

range of motion

dexterity and Carroll score of the affected fingers in the study group were significantly higher than those in the control group

and the difference was statistically significant（P<0.05）. One year after operation

the scores of physiological

psychological

environmental and social relations in the WHO-QOL100 scale of the study group were significantly higher than those of the control group

and the difference was statistically significant（P<0.05）. Conclusion After bridging replantation of severed fingers with perforator bone flap of anterior tibial artery

ERAS intervention is helpful to improve the blood supply of amputated finger

relieve pain

improve the survival rate of amputated finger

improve the motor function of affected finger and improve the quality of life.
