RESUMO
Surgery of the wrong side is a very uncommon complication in orthopaedic surgery, but with serious consequences for the patient, the surgeon and the health institution, having to put all the necessary measures in place to prevent this occurring. We have conducted a prospective study on the introduction of a protocol to prevent surgery of the wrong side in 101 patients operated on for any foot disease in the Major Surgery Ambulatory Unit, performing three independent controls to verify the side: by the patient, by the nurse and by the anaesthetist. We review the information available of the side in the medical records and their correlation with the side operated on. Almost a quarter of the patients, 24.8%, were not informed that they had to make a mark on the foot to be operated on. No mark was made by 18.4% of the patients informed to do so, with no relationship between age, gender, education level, to live alone or previous foot operations. There was a lack of noting the side in the documentation, with this omission being more frequent in the Orthopaedic and Traumatology and Anaesthesiology medical records. Nine cases of inconsistency in the surgical side were detected, all in patients who had previous surgery in any foot. Marking of the side has been incorporated as routine practice in foot surgery, being beneficial for the safety of the patient, and should become normal practice in all surgical areas in the near future.
