Thoracic epidural analgesia versus intravenous patient-controlled analgesia for the treatment of rib fracture pain after motor vehicle crash.

BACKGROUND

Pain from rib fracture pain may affect pulmonary function, morbidity, and length of intensive care unit stay. Previous trials have varied epidural technique within the study and have used several outcome variables.

METHODS

The charts of patients who sustained rib fractures after a motor vehicle crash between January 1, 1994, and June 30, 1997, were reviewed. Data were collected from 64 patients who had three or more rib fractures and initiation of intravenous patient-controlled analgesia with morphine or thoracic epidural analgesia with bupivacaine and fentanyl within 24 hours of admission.

RESULTS

Injury Severity Score and Acute Physiology and Chronic Health Evaluation II scores were not significantly different between groups. Patients in the epidural group had significantly more rib fractures and were significantly older. Patients who received epidural analgesia had significantly lower pain scores at all times. There were no differences in the lengths of intensive care unit or hospital stays, or the incidence of pulmonary complications or organ failure between groups.

CONCLUSION

Thoracic epidural analgesia with bupivacaine and fentanyl provided superior analgesia than intravenous patient-controlled analgesia morphine.
