Study Arms:
- Phase A - Thoracic ES with LOR (Type: EXPERIMENTAL): Patients will receive thoracic epidural anesthesia. The thoracic epidural needle will be introduced until loss of resistance (LOR) is perceived to identify the thoracic epidural space (ES). The Compuflo Epidural Instrument will be used to record pressure readings. The thoracic epidural procedure will then continue per standard of care.
- Phase B - Thoracic ES with Compuflo (Type: EXPERIMENTAL): Patients will receive thoracic epidural anesthesia. The thoracic epidural needle will be introduced until the Compuflo Epidural Instrument indicates that pressure has decreased. The loss of resistance technique will then be used to identify the thoracic epidural space. The thoracic epidural procedure will then continue per standard of care.

Based on this trial design, predict the completion outcome and termination type (if applicable).
