Effect of Bupivacaine Infiltration in the Track of the Spinal Needle on Back Pain for Elective Caesarean Section Under Spinal Anesthesia

Background: Back pain is one of the reasons for the patient's refusal of spinal anesthesia. Objective: To evaluate the efficacy of bupivacaine infiltration at the site of a spinal needle injection in reducing post-spinal back pain and using analgesics for post-spinal back pain. Methods: From July to August 2021, a prospective study was conducted on 60 patients getting spinal anesthesia for elective cesarean sections at Erbil Maternity Teaching Hospital. Group A (got bupivacaine) at the spinal needle track; group B (did not receive bupivacaine). We use a visual analog scale to assess pain severity. Results: In the first and third postoperative days, group A experienced significantly less post-spinal back discomfort (1.87 and 0.33) than group B (3.90 and 1.77). Furthermore, group A used much fewer analgesics on the first postoperative day (0.20); on the third postoperative day, they used none, in contrast to group B's 1.07 and 0.30. Conclusions: Bupivacaine infiltration along the spinal needle track is an excellent approach for reducing post-spinal back pain and the usage of analgesics.
