Summary: | Abstract Study Objectives To investigate pressure waveform-guided epidural catheter placement (PWEP) and its effect in clinical practice. Design Single-center, prospective cohort study. Setting University teaching hospital. Patients 3,326 patients undergoing thoracic, abdominal, and lower limb surgery. Interventions 1,614 underwent PWEP and 1,664 had the loss-of-resistance (LOR) technique. Measurements Anesthesia success and catheter replacement-related complications were recorded. Main Results The specificity and sensitivity of PWEP was higher than LOR, and it also provided higher satisfaction with anesthesia when compared with the LOR technique (62.8% vs 45.6 %; P < 0.05). PWEP also performed better than LOR in risk of anesthesia failure (0.4% vs 1.1%; P < 0.05) and catheter replacement-related complications (0% vs 0.6%; P < 0.05). Conclusion PWEP is a reliable and useful technique for epidural catheter placement. |
