Observation on the effect of replantation of severed finger without shortening under microscope in patients with finger amputation
Objective To evaluate the advantages of microscopic replantation of severed fingers without shortening in the treatment of patients with finger amputation,in order to provide reference for the treatment of such patients.Methods The clinical data of 150 patients with terminal finger amputation in our hospital from May 2020 to May 2022 were retrospectively selected,and they were divided into study group(78 cases)and routine group(72 cases)according to the surgical method.The study group was treated with microscopically unshortened severed finger replantation,and the conventional group was treated with conventional severed finger replantation.The clinical efficacy,stress indexes(cortisol(Cor),norepinephrine(NE),adrenocorticotropin(ACTH)),blood circulation[blood flow velocity,resistance index(RI)]and recovery of severed finger were compared between the two groups.Results The operative rate of the study group was 94.87% ,the survival rate of the skin flap was 98.72% ,which were higher than 76.39% and 88.89% in the conventional group(P<0.05).The concentrations of Cor,NE and ACTH in the study group were lower than those in the conventional group at 3 and 7 days after surgery(P<0.05).At 1 month,3 months and 6 months after operation,the blood flow velocity in the study group was higher than that in the conventional group,and the RI was lower than that in the conventional group(P<0.05).The severed finger length,two-point discrimination perception and fingertip joint motion in the study group were better than those in the conventional group(P<0.05).Conclusion Replantation without shortening of severed finger under microscope can reduce stress response,improve blood flow of severed finger,increase the survival rate of skin flap and improve prognosis.
