Risk Factors Associated with Somato-Visceral Pain Investigation, in Scheduled Cesarean Section under Epidural Anesthesia with Lidocaine 2% and Adrenaline

Abstract

Background: Epidural anaesthesia with 2% lidocaine has been reported to be more effective in caesarean section, but somato-visceral pain remains a potential complication, and can generate many dire effects including mother psychological impairment and burden. Pain during caesarean deliveries is a challenge, but any study was performed to identify risk factors associated to it.We conducted this study to identify pain risk factors, investigate whether surgical anaesthesia length is sufficient, and discover possible correlation between pain rate and surgery duration, while assessing 2% lidocaine efficacy. Methods and methods:This study enrolled 612 patients who underwent scheduled caesarean section under 2% lidocaine epidural and adrenaline, at 1st affiliated hospital of Chongqing medical university in 2019. Pain was considered only for patients with successfully epidural anaesthesia. Exclusion criteria included emergencies and general anaesthesia, 100 mmhg < baseline systolic blood pressure > 140 mmhg, pregnancy term < 37 weeks and > 42 weeks. SPSS 25.0 was used and adequate tests were performed for statistical analysis. P < 0.05 was adopted for statistical significance.Results: Total local anaesthetic dose < 12 ml was more likely associated with pain during caesarean section than a total local anaesthetic ≥ 12 ml. Baseline systolic blood pressure < 120 mmhg was greater associated with pain during caesarean section than that > 120 mmhg. Maternal height > 160 cm was also associated pain during caesarean section. Conclusion:The variables involved in pain prevalence were total local anesthetic dose, systolic baseline blood pressure, and parturient height. Surgical analgesia length was overall judged sufficient. There was no correlation between pain rate and surgery duration. The identified risk factors associated with pain will help to reduce pain incidence and will help to improve mother-baby peripartum condition.
