Incidence of nosocomial infections associated with surgical procedures

Nosocomial infections are referred to as healthcare associated infections (HAI'S), are infections acquired during the process of receiving health care.The study's main goal is to determine the prevalence of nosocomial infections in patients through various surgical procedures.In order to find out the risks associated with surgical procedures, a total of 180 samples were collected twice a day on different days of a week for two months immediately before and after surgery was performed.Samples were collected using wet swabs and were taken from operation table, endotracheal tube, anaesthesia-ventilator inlet and analysed for the presence of pathogens such Salmonella spp, Escherichia coli and Staphylococcus spp as well as the total viable count.Serial dilutions were made for each sample for further analysis.Colonies were counted using digital colony counter and each plate appear to have colonies ranging from 30-300.The results showed that the total viable count in samples collected both before and after performing surgery in a veterinary hospital operation theatre table were significantly (P<0.001)lower when compared with endotracheal tube and anaesthesia-ventilator inlet.Salmonella spp were more commonly noticed before and after surgery than Escherichia coli and Staphylococcus spp.Proper managemental practices and surveillance could reduce the incidence of nosocomial infection in surgery.
