Factors Affecting the Timing of Antibiotic Administration Before Artificial Knee Replacement Surgery in Songkhla Hospital

Abstract

            Management of antibiotics before surgery is considered necessary for surgery patients to prevent postoperative infection, which requires patients to receive antibiotics before surgery for at least 30-60 minutes in order to increase their efficacy. However, in some cases, drug administration did not meet the above criteria and did not know the consequences. In this descriptive study, the purpose of this study was to investigate factors affecting the timing of antibiotic administration before knee replacement surgery of osteoarthritis patients in Songkhla Hospital and to study the effect of antibiotic administration on the basis. (30-60 minutes) and did not meet the criteria (< 30 minutes) before knee replacement surgery on surgical wound infection of osteoarthritis patients in Songkhla Hospital classified by type of receiving anesthesia. The study subjects were 67 patients with osteoarthritis who underwent artificial knee replacement surgery in Songkhla Hospital. The instrument used was the data record form that affected the duration of antibiotic administration before surgery.  Data were analyzed using frequency distribution, percentage, mean, standard deviation and Chi – square test. 

              The results showed that anesthesia drugs were not significantly related to antibiotic administration time before surgery at level of 0.05. Moreover, antibiotic administration time and surgical wound infection found that all patients were not infected with surgical wounds, even though administering antibiotics less than 30 minutes, which is probably the result of the surgical team complying with the standards. Disease control in which is a risk factor for the body's infection, operating standards compliance, compliance with standard procedures for patients with artificial knee replacement surgery to reduce surgical wound infection.
