A Comparative Analysis Of Primary Suture And Delayed Suture In Dogs Bite Wounds On The Head And Face

ObjectiveAnalyze the clinical effects of primary suture and delayed suture on the wound infection and healing aesthetics of craniofacial dog bite,and provide a reference for the clinical treatment of craniofacial dog bite.MethodsCollected the clinical data of 296 dog bite patients from January 2019 to January2020 in the Rabies Exposure Prevention and Treatment Clinic of the Emergency Department of the Fifth Affiliated Hospital of Zhengzhou University,and conducted a retrospective analysis.According to their treatment methods,they were divided into185 cases in the one-stage suture group and 111 cases in the delayed suture group.The wounds of the two groups of patients followed the rules for postexposure prophylaxis treatment of rabies.Patients in the primary suture group trimmed the skin edge and sutured the wound,covered with sterile accessories.Patients in the delayed suture group directly covered the wound with a sterile dressing after the wound was treated,changed the dressing on time,and the wound was sutured delayed.Both groups of patients were routinely used antibiotics to prevent infection after surgery,and the amount of children was calculated and adjusted according to weight.Inject rabies vaccine on time and actively prevent tetanus.Comparative analysis of the clinical efficacy of wound infection and healing in the two groups of patients.ResultsAmong the 185 patients in the primary suture group,15 cases(8.11%)had different degrees of wound infection.Among the 111 patients in the delayed suture group,7 patients(6.31%)had wound infections of different degrees.There was no significant difference in wound infection rate between the two groups(P>0.05).A total of 158 patients in the primary suture group(85.41%)had the best wound healing,the average wound healing score is 4.95±0.63,and a total of 68 patients in the delayed suture group(61.26%),the average wound healing score is 4.40±1.39.There was a statistically significant difference in the best wound healing scores between the two groups(P<0.05)).There was no systemic infection in the two groups of patients,and neither rabies nor tetanus occurred during the half-year follow-up.ConclusionComparing the primary suture and delayed suture of head and face wounds for dog bite,although the wound infection rate of the primary suture group was higher than that of the delayed suture group,there was no significant difference in the infection rate between the two groups(P>0.05).However,comparing the best wound healing,the primary suture group has better wound healing effect than the delayed suture group.It is recommended that the wound should be sutured first after full treatment of the head and face dog bite wound.
