Correlative factors of post-dural puncture backache in cesarean section
Authors
Abstract
Introduction: Spinal anesthesia is an optional method chosen for cesarean section. One main reason for the decline of this method is backache. This study was conducted to investigate the factors associated with post-dural puncture backache in cesarean section. Materials and Methods: This cross-sectional study was carried out on 200 patients aged 20-40 years old, who were candidates for Cesarean section under spinal anesthesia. The patients’ physical status of American Society of Anesthesiologists was I and EI in 12 months. The procedures were performed in sitting position, with a disposable 25-gauge needle, 75 mg Lidocaine 5% and 25 micrograms Fentanyl. The patients were followed up for incidence of backache in the first 24 hours and the first week after spinal anesthesia. Results: Incidence of backache in the first 24 hours was 5% and in the first week after spinal anesthesia it was 9.5%. There was a significant relationship between age, dural puncture in the lower part, post-dural puncture headache, high spinal anesthesia, nausea, vomiting and backache in the first 24 hours. Moreover, there was a significant relationship between age, nausea, vomiting and backache in the first week after spinal anesthesia (P<0.05). Conclusion: Early age, dural puncture in the lower part, high spinal anesthesia, nausea, vomiting, high spinal anesthesia and post-dural puncture headache increased the possibility of post-dural puncture backache.
