Cytokines play an important role in immune regulation and fetal lung development. The systemic inflammatory response in newborns with congenital diaphragmatic hernia (CDH) has not been characterized so far. We compared various concentrations of cytokines in serum from newborns with CDH and in healthy term neonates. We analyzed cytokine patterns of CDH newborns under extracorporeal membrane oxygenation (ECMO) and mechanical ventilation (MV).38 newborns with CDH were included: ECMO group (n=13) and non-ECMO group (n=25). Healthy term neonates served as controls (n=13). Serum samples were obtained prospectively after birth and during therapy.Concentrations of IFN-α, IL-3,-6,-7,-8,-10, MIP-1α,-1β and TNF-α in serum of newborns with CDH were higher than in umbilical cord blood of term neonates. Infants with severe CDH requiring ECMO therapy had higher postnatal IL-8,-10, and MIP-1α levels than newborns with milder disease in the non-ECMO treated group. IL-10 progressively decreased during the first 3 days following birth under ECMO. In contrast, the chemokine MIP-1α remained elevated during ECMO therapy compared to mechanically ventilated CDH newborns.The pattern of cytokines in the serum of newborns with CDH showed significant elevations compared to term neonates. Our findings indicate that CDH is associated with systemic inflammatory response immediately after birth. ECMO and MV show a similar increase of IL-1α and IP-10 in CDH newborns assuming a persistent pulmonary inflammatory reaction irrespective of the conducted treatment.
Minimally invasive fetoscopic surgery for spina bifida aperta is a new therapeutic approach to preserve neurologic function by protecting exposed neural tissue. The anesthetic management is of paramount importance for the success of the procedure. Therefore, our protocol was developed with particular attention to safe and adequate maternal and fetal anesthesia, sufficient uterine relaxation as well as prevention of pulmonary edema, placental abruption, and spontaneous labor. As illustrated by this retrospective analysis of 61 cases, these goals can be reliably achieved. The clinical protocol is presented as a supplemental digital content to this manuscript (Supplemental Digital Content 1, http://links.lww.com/AA/B733).

Liberal administration of tocolytic drugs (e.g. indomethacin) and intravenous fluids along with high concentrations of volatile anesthetic gases during fetal surgery are thought to contribute to the development of maternal pulmonary edema. Consequently, during the introduction of the Minimally Invasive Fetoscopic Approach (MIFA) for the closure of fetal spina bifida aperta (SBA), Hering and Kohl identified a general anesthetic technique that reduced concentrations of volatile anesthetic and thus minimized adverse side effects of deep anesthesia (hemodynamic depression, pulmonary edema, and need for vasopressor support). In this retrospective case series, the authors described their own clinical experiences with a modified Hering-Kohl-Protocol in patients undergoing MIFA for SBA. In this modified protocol, vasopressor management is guided by pulse contour analysis (PiCCO) alone and atosiban is the first-line agent for perioperative tocolysis instead of indomethacin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
