Abstract
Surgeries of the knee are associated with moderate to severe postoperative pain. Uncontrolled
postoperative pain has an adverse sequel of delayed resumption of normal pulmonary function, restriction of
mobility, nausea and vomiting, increase in the systemic vascular resistance, cardiac work, and myocardial oxygen
consumption. So these procedures are better to be done under regional anesthetic techniques which reduce
neuroendocrinal stress responses, central sensitization of the nervous system and muscle spasms which occur in
response to painful stimuli. Recently, among these regional anesthetic techniques PNB are gaining popularity
because they reduce the possibility of complications and side effects associated with the central blocks. Femoral
block provide effective analgesia with potentially fewer complications and side effects than epidural blocks. The
purpose of this study was to compare between epidural analgesia and femoral nerve block in adult patients
undergoing total knee replacement including comparison of analgesic efficacy, side-effects, and complications. The
study was performed upon 40 patients, aging 40-70 years, and randomly distributed among two groups: group A:
20 patients received lumbar epidural analgesia. group B: 20 patients received femoral nerve block. For each
patient, the following data were collected: age, sex, weight, height, ASA, duration of surgery, hemodynamic
changes, incidence of postoperative complications, pain scores. The results showed that performing femoral nerve
block provided effective analgesia, equivalent rehabilitation and duration of hospital stay in addition to fewer
complications in comparison to epidural analgesia such as hypotension, postoperative vomiting and urinary
retention.
