This experimental in vitro study aimed to investigate the antibacterial effect of levobupivacaine on Staphylococcus aureus in a patient-controlled analgesia (PCA) model at concentrations commonly used for postoperative pain treatment (0.125%) and painless labour (0.0625%). The antibacterial activity was evaluated using colony count reduction and supported by Scanning Electron Microscope (SEM) imaging.
