The anti-epileptic drugs such as gabapentin and other non-steroidal anti-inflammatory drugs (NSAID) such as celecoxib were used as a part of multimodal analgesia to control such pain. Gabapentin is an anticonvulsant drug that has analgesic effect in post-herpetic neuralgia, diabetic neuropathy, and neuropathic pain. Celecoxib is one of the NSAIDs, that its analgesic effect is reported in various studies by cyclooxygenase-2 (COX-2) inhibitor.

The aim of this randomized double-blinded study was to asses and compare the efficacy of using gabapentin versus celecoxib as a part of multimodal analgesia in perioperative hemodynamic control and pain relief in patients underwent posterior approach lumbar spine disc fixation surgery.

Inclusion Criteria:

• American society of anesthesiologists (ASA) I and II, aged between 21-60 years old scheduled to undergo elective posterior approach lumbar spine disc surgery

Exclusion Criteria:

• Patients with a known sensitivity to celecoxib or pregabalin, psychotic disorder or cognitive impairment, history of drug dependency or substance addiction, history of chronic medical disease, the presence of coagulation disorders or pregnancy, were excluded from the study.
