Analysis of the high incidence factors of infection after open tension-free inguinal hernia repair in adults

Abstract

Objective To explore risk factors for surgical site infection after tension-free inguinal hernia repair in adults and intervention measures. Methods We retrospectively analyzed the clinical date of 1 500 adult patients treated open tension-free inguinal hernia repair from January 2010 to January 2017 in the People's Hospital of Aba Tibetan and Qiang Autonomous Prefecture. The surgical site infection of the patients was retrospectively analyzed by single factor. Results The results related indicators of age, operation time, prophylactic antibiotic drugs and underlying diseases was statistically significant (P<0.05). Differences in the intensity of the risk factors associated with infection from low to high: age, underlying diseases and operation time. By analyzing surgical site infections in patients' age factor and the level of danger, we found that surgical site infection incidence with age and the risk level significantly increasing. The resistance rate of gram-positive bacteria to penicillin and sulfamethoxazole file was higher, and the resistance rate of gram-negative bacteria to ampicillin was higher generally. Conclusion The risk factors for surgical site infection after open tension-free inguinal hernia repair in adults are operation time, underlying diseases and age. Targeted anti-infective drugs should be used for treatment of infected patients. Key words: Hernia, inguinal; Herniorrhaphy; Surgical site infection; Intervention analysis
