Nosocomial infection following video-assisted thoracoscopic surgery ; Infección nosocomial después de cirugía toracoscópica videoasisitida

Objectives: To assess the incidence and risk factors for nosocomial infection after video-assisted thoracic surgery (VATS). Methods: Prospective cohort study of all consecutive pa tients who underwent VATS surgery during 20 months. Pa tients were visited on a daily basis and followed up until they were discharged from the hospital Results: During the study period 217 patients (70.1% men; mean age, 50.9 years, range 15-85 years) underwent VATS. Fourteen (6%) episodes of postoperative infection were diagnosed in 13 patients, including pneumonia (n = 2), lower respiratory tract infection (n = 9), surgical site infection (n = 2), and urinary tract infection (n = 1). Prior inmunosupresion (adjusted odds ratio [OR], 2.70; 95% confidence interval [CI],1.52-4.84), prior infections (OR, 14.9; 95% CI 1.91-116.5), pre operative stay > 2 days (OR, 3.37; 95% CI 1.00-11.40), neopla sia (OR, 3.69; 95% CI, 1.94-7.06) duration of surgery > 45 min utes (OR, 5.91; 95% CI, 1.00-36.40) and presence of central venous catheter (OR, 16.40; 95% CI, 2.29-117.20), were inde pendent risk factors for nosocomial infection. Conclusions: Nosocomial infection rate after VATS was low. Respiratory infection was the most common infection. Factors which affect patient immunity, preoperative stay and perioperative-related variables were independently associated with infection. ; Objetivos: Estudiar la incidencia y los factores de riesgo de infección nosocomial en pacientes sometidos a una cirugía toracoscópica videoasistida.
