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. (C) 2014 Elsevier Inc. All rights reserved.
