A Comparison of Gabapentin and Ketamine in Acute and Chronic Pain

Gabapentin versus Ketamine

mechaal benali, PROFESSOR

Patients were randomized into two groups: Group Gabapentine ( G group) received 600 mg of Gabapentin (two tablets) two hours prior to surgery and saline solution before induction of spinal anesthesia and group Ketamine ( K group) received two placebo tablets and an injection of ketamine at a dosage of 0.15 mg/Kg before induction of spinal anesthesia.. During the surgery, blood pressure and heart rate were monitored. Postoperative analgesia was provided by a PCA morphine. Acute postoperative pain was assessed by a visual analog scale. The incidence of postoperative neuropathic pain was detected by the DN4 questionnaire after one and three months of surgery.

the investigators includes patients aged at least 18 classified as ASA I and II. Patients with significant cardiovascular or central nervous system disease, as well as those with renal or liver failure and those who could not operate the PCA device were not eligible for our study.

Exclusion criteria were patients that had incidents during the surgery such as: an allergic reaction, local anesthetic systemic toxicity or a surgical incident.

Patients were randomized into two groups: Group Gabapentine ( G group) received 600 mg of Gabapentin (two tablets) two hours prior to surgery and saline solution before induction of spinal anesthesia and group Ketamine ( K group) received two placebo tablets and an injection of ketamine at a dosage of 0.15 mg/Kg before induction of spinal anesthesia.

Upon arrival in the operating room, patients were monitored using mean blood pressure, heart rate and peripheral oxygen saturation monitors.

The surgery was performed under spinal anesthesia. Each patient received 10 mg of hyperbaric bupivacaine mixed with 5 µ of sufentanil.

Immediately after the intervention, the patients were transferred to the post anesthesia care unit (PACU) where analgesia was arranged through morphine titration.

After the motor block is lifted, patients were transferred to surgery department where they were connected to a PCA device that provided 1 mg IV bolus injection of morphine at a lockout interval of 7 minutes and with a maximum four-hour limit of 0.5 mg/Kg.

During the hospital stay, acute post-operative pain assessed through the visual analog scale (VAS) at rest and at motion, every 15 minutes in the PACU and then at H2, H6, H12 and H24 postoperative.

The morphine consumption was noted as well as its first demand. Sedation was assessed using the Ramsay score. The occurrence of adverse effects such as nausea and vomiting, dizziness, diarrhea, hallucination and pruritus was also noted.

The first night sleep quality was evaluated through the Spiegel score. After hospital discharge, patients were contacted at one month and three months. The incidence of post-operative neuropathic pain was detected by the DN4 questionnaire. The effect the pain had on their daily activities was also judged.

Statistical analysis:

According to available data (30% occurrence of post-operative chronic pain after inguinal hernia repair (2)), to decrease by 25% this number with a power of 80%, 28 patients were needed in each group.

Statistical analysis was performed with SPSS in its 20 version. Results were expressed as mean, standard variation or median. χ2 test, fisher's exact test and Mann-Whitney test were performed. A P value of \< 0.05 was considered as statistically significant.
