Polysomnographic Parameters in Anaemic InfantsBefore and After Transfusion
T.Erler, M.D., J.Oppermann, M.D., and E.Wischniewski, M.D.
Apnoea and periodic breathing are common problems in premature babies,the mecha-
nisms are still unclear.But it is well-known that anaemia plays a significant role in the patho-
genesis of these disorders.The borders between tolerable hemoglobin-hematocrit reduc-
tion in infants and pathological anaemia,which may endanger undisturbed growth in
infants,are blurred.Therefore the attempt to observe breathing and circulation in cases of
anaemia through the use of a polysomnography is recommended.Irregularities should be
remedied after balancing the anaemia.Examinations of 12 infants with anaemia in a sleep
research laboratory were compared both before and after transfusion of erythrocytes.
While sleep patterns showed no significant changes,certain breathing and circulatory
parameters such as the incidence of central apnoea,mean heart rate or mean breathing
showed significant drops.A complete polysomnography may be helpful in determining
whether a blood transfusion should be undertaken or not.(Sleep and Hypnosis
