Intra-incisional injection of magnesium sulfate for post cesarean pain management

Abstract

Background and objectives: cesarean section is estimated for about 30% of child births worldwide and it is one of the most common surgical procedures. Pain relief after cesarean delivery is especially important as the consequences of inadequate pain relief are expressed not only by the mother but by the newborn as well. Magnesium has been reported to produce important analgesic effects including the potentiation of morphine analgesia, attenuation of morphine tolerance and the suppression of neuropathic pain. The objectives of this study were to determine the efficacy of intra-incisional injection of magnesium sulfate for post cesarean pain management as in patient underwent elective cesarean section and the reduced need for extra analgesic use postoperatively. Methods: a randomized, placebo controlled, single-blinded study with a total of 200 pregnant participants scheduled for cesarean section in Sulaimani maternity teaching hospital, from 1st of May 2016 to 15th of August 2016. Patients were randomly allocated to two groups, those with odd numbers were assigned to case group (100) received 750mg of magnesium sulfate and patients with even numbers assigned to the placebo group (100) received 20mg of normal saline. Results: The mean Visual Analogue Score after 4 hours, 8 hours, 12 hours and 24hours was significantly less for the intervention (Magnesium sulfate) group when compared with the control (Normal Saline). Conclusions: Subcutaneous administration of magnesium sulfate in post cesarean section pain management can be used as a successful modality or method for pain management.
