Use of pudendal nerve block among midwives in Norway: A national cross-sectional study

Abstract

Introduction: Pudendal nerve block (PNB) is an effective analgesic during the second stage of labor and for suturing. With the introduction of epidural and spinal analgesia, PNB use decreased considerably. Most midwives receive some teaching on PNB during their midwifery education. The aim of this study was to examine the use of PNB by midwives in Norway. Methods: This was a cross-sectional study, in January 2020, using an electronic questionnaire which was distributed to approximately 1500 midwives. Results: A total of 527 midwives responded to the questionnaire (35%). Less than half (44.6%) of the midwives used PNB, of whom only half (123/235) used it frequently (at least once a month). The use of PNB was most common at specialized obstetric units with ≥1500 births per year. Midwives who reported good theoretical knowledge and practical skills of PNB used it significantly more often than midwives not reporting these (p<0.001). Reasons for not using PNB were: the lack of practice and experience (72.6%), and never having been taught (42.8%). Midwives reported needing training (83%) and clinical support to start using PNB (43%). Conclusions: Few midwives use PNB regularly. To increase the use of PNB, midwifery education needs to include both theoretical and practical skills teaching. Midwives with insufficient knowledge and skills require the same teaching and training. In the clinical area, midwives require clinical support and supervision to practice and gain experience. Women are not offered PNB as long as midwives are not confident in providing this method of pain relief.
