[Cardiorespirographical monitoring in neonatal pre- and postoperative care (author's transl)].

A further improvement of the chance of survival in neonatal surgery can be achieved by close cardiorespirographical observation. Neonates with adaptation problems should be operated upon -- if malformation permits surgery and there is no absolute urgency -- not before normalization of the cardiorespirogram. Stress of operation and anaesthesia lead to cardiac dysregulations in the very early postoperative stage. Deceleration of the heart beat rate due to respiration or a silent cardiogram with decrease of the beat rate and respiratory depression should be regarded as dangerous disturbances.
