A different perspective: anesthesia for extreme premature infants is there an age limitation or how low should we go?

Purpose of review To put in perspective, the various challenges that faces pediatric anesthesiologists because of the recently lowered limits with regards to the viability of a fetus. Both medical and ethical considerations will be highlighted. Recent findings Issues related to: who should anesthetize these tiny babies; can we provide adequate and legal monitoring during the anesthetic; does these immature babies need hypnosis and amnesia and the moral/ethical implications associated with being involved with care of doubtful long-term outcome are reviewed. Summary There does currently not exist sufficient research data to provide any evidence-based guidelines for the anesthetic handling of extreme premature infants. Current practice relies on extrapolations from other patient groups and from attempting to preserve normal physiology. Thus, focused research initiatives within this specific field of anesthesia should be a priority. Furthermore, in-depth multiprofessional ethical discussions regarding long-term outcome of aggressive care of extremely premature babies are urgently needed, including the new concepts of disability-free survival and number-need-to-suffer.
