Abstract
BACKGROUND:Pain is considered as an importantissue after cesarean section. Multimodal approach to post cesarean pain management may not only enhance analgesia but also reduce side effects after the surgery. OBJECTIVES: This study was aimed to evaluate the clinical efficacy of subcutaneous injection of low dose ketamine at the incision site to reduce cesarean section pain. PATIENTS AND METHODS: Sixty patients, aged between 18 and 25 years old, scheduled for elective cesarean section, were enrolled to this double-blind randomized controlled trial study. Patients were divided into three groups of 20 patients each group one (k-pre) received 0.5 mg/kg ketaminebefore skin incision and normal saline after skin closure, group two (k-post) received normal saline before skin incision and 0.5 mg/kg ketamine after skin closure and group three (C) received normal saline before skin incision and after skin closure; subcutaneously at the incision site. The firstanalgesic request, the amount of analgesic and the pain intensity were evaluated for 24 hours. RESULTS: The first time analgesic requested was longer and the amount of analgesic used during the first 24 hours was significantly lower in groups K-pre and K-post compared with group C (P < 0.05). Pain intensity was significantly lower at 2, 4, 6 and 12 hours in groups K-pre and K-post compared with group C (P < 0.05). Nevertheless, pain intensity was not significantly different at 18 and 24 hours in group C (P > 0.05). The first requested time, total used amount of analgesicand pain intensity were not meaningfully different in K-pre and K-post groups (P > 0.05). CONCLUSIONS:Patients who were given ketamine before or after cesarean section subcutaneously at incision site had lower pain intensity and less analgesic consumption than patients who were given placebo.

Abstract
OBJECTIVE:Nowadays, conventional analgesic agents, which are widely used for pain relief after cesarean section, provide suboptimal analgesia with occasional serious side effects. We designed a randomized, double-blind, placebo-controlled study to evaluate the analgesic efficacy of intrathecal ketamine added to bupivacaine after cesarean section. METHODS:Sixty patients scheduled for cesarean section under spinal anesthesia were randomly allocated to one of the two groups to receive either bupivacaine 10 mg combined with 0.1 mg/kg ketamine, or bupivacaine 10 mg combined with 0.5 mL distilled water intrathecally. The time to the firstanalgesic request, analgesic requirement in the first 24 hours after surgery, onset times of sensory and motor blockades, the durations of sensory and motor blockades, and the incidences of adverse effects such as hypotension, ephedrine requirement, bradycardia, and hypoxemia, were recorded. RESULTS:Patients who received ketamine had a significantly prolonged duration of anesthesia compared with those who did not in the control group [95% confidence intervals (CI) 195-217; p = 0.001]. The mean time to the first analgesic request was also significantly longer in ketamine group (95% CI 252.5-275; p < 0.001). The total analgesic consumption in the 24 hours following surgery significantly lessened in the ketamine group compared with that of the control group (95% CI 2-2.5; p < 0.001). The two groups did not differ significantly in intraoperative and postoperative side effects. CONCLUSION:Intrathecal ketamine 0.1 mg/kg co-administered with spinal bupivacaine elongated the time to the first analgesic request and lessened the total analgesic consumption in the first 24 postoperative hours in comparison with bupivacaine alone in the control group following elective cesarean delivery.

Abstract
BACKGROUND:Suitable analgesia after cesarean section helps mothers to be more comfortable and increases their mobility and ability to take better care of their infants. OBJECTIVES:Pain relief properties of ketamine prescription were assessed in women with elective cesarean section who underwent spinal anesthesia with low dose intravenous ketamine and midazolam and intravenous midazolam alone. PATIENTS AND METHODS:Sixty pregnant women scheduled for spinal anesthesia for cesarean section were randomized into two study groups.Ketamine (30 mg) + midazolam (1 mg = 2CC) or 1mg midazolam (2CC) alone, was given immediately after spinal anesthesia. Pain scores at first, second and third hours after CS operation, analgesic requirement and drug adverse effects were recorded in all patients. RESULTS: Ketamine group had significant pain relief properties in compare with control group in first hours after cesarean section (0.78 ± 1.09 vs. 1.72 ± 1.22, VAS score, P = 0.00). Total dose of meperidine consumption in women of ketamine group was significantly lower than women of control group (54.17 ± 12.86 vs. 74.44 ± 33.82 mg, P = 0.02). There were no significant drug side effects in participated patients. CONCLUSIONS: Intravenous low-dose ketamine combined with midazolam for sedation during spinal anesthesia for elective Caesarean section provides more effective and long lasting pain relief than control group.
