Pain Scores after Open Fetal Spina Bifida Repair and Caesarean Section: A Longitudinal Cohort Study

Abstract

<b><i>Introduction:</i></b> In fetal surgery, successful pain management is crucial for postoperative mobilization, prophylaxis of contractions, and fast recovery. This study analyzed patient’s pain experience after open fetal spina bifida (fSB) repair in comparison to pain scores after the subsequent Caesarean section (C-section). <b><i>Materials and Methods:</i></b> Data were collected with a questionnaire given to 91 women, who had fSB repair and then C-section at our center between 2019 and 2022. It comprised 12 questions covering different aspects of pain experience and satisfaction with pain therapy and was answered by 67 women after fSB repair and 53 after C-section. Postoperative pain was rated on a Likert scale from 0 (slight/rarely) to 100 (strongest/always). Outcomes after fSB repair were compared to those after C-section. Additionally, subgroup analysis compared outcomes of women with different pain levels (group 1–5) after fSB repair. <b><i>Results:</i></b> Compared to women after C-section women after fSB repair reported significantly higher maximum pain scores (MPS) (<i>p</i> = 0.03), higher sleep disturbance due to pain (<i>p</i> = 0.03), and sedation rates (<i>p</i> = 0.001) as side effect from pain therapy. No differences were found regarding feelings of insecurity (<i>p</i> = 0.20) or helplessness (<i>p</i> = 0.40), as well as involvement in (<i>p</i> = 0.3) and satisfaction with pain therapy (<i>p</i> = 0.5). Subgroup analysis revealed that women with higher MPS after fSB repair were significantly more often non-Caucasians (<i>p</i> = 0.003) and more often affected by pain while lying in bed (<i>p</i> = 0.007) and during mobilization (<i>p</i> = 0.005). Additionally, they reported higher rates of dizziness (<i>p</i> = 0.02) and lower satisfaction rates with pain therapy (<i>p</i> = 0.03). Postoperative complication rate did not differ among groups. <b><i>Conclusion:</i></b> Although women after fSB repair reported higher MPS compared to after C-section, the current pain management was generally perceived as satisfactory.
