Considerations in selecting postoperative analgesia for pregnant sheep following fetal instrumentation surgery

Abstract

Implications • As a model of human pregnancy, research studies in catheterized fetal sheep have made significant contributions to our understanding of both normal and abnormal fetal development. • Owing to the invasive nature of catheterization surgery, effective postoperative analgesia is required. • Decisions regarding appropriate analgesia should consider effectiveness in reducing maternal pain and fetal well-being as well as potential impacts upon fetal physiological parameters under investigation. • The reporting of analgesic regimes in all research studies should comply with the ARRIVE guidelines.
