Introductin: Premature or anemic newborns undergoing hernia repair
are prone to more postoperatie complicatins than full-term infants. The
incidence of respiratory complicatins among these patints is more than 30%,
with postoperatie apnea being the most common. Some investiators found
that gestatinal and postconceptinal age, the presence of contiuing apneic
episodes and anemia are the main determinants of postoperatie apnea. It
seems that infants who do not receive intravenous anesthetis experience less
respiratory complicatins. Intravenous anesthetis have hepati metabolism
for eliminatin and the immature liver of the premature neonate has not
suffient eliminatin capacity.
Materials and methods: Study partiipants were 1047 neonates with post
conceptual age (PCA) lower than 60 weeks undergoing inguinal hernia
operatin. Sevoflrane gas mask was used for anesthesia inductin and during
deep anesthesia, caudal block was administered using 1cc/kg bupivacaine 2%.
The neonates were managed with spontaneous breathing with Sevoflrane
gas mask or endotracheal tube unti the end of the operatin.
Results: In the present study, 916 (87.5%) male and 131 (12.5%) female
neonates were included. Mean gestatinal age and PCA were 36.62±3.80
and 46.80±4.56 weeks respectiely. Postoperatie apnea did not occur in any
patint .
Conclusion: Many studies confim our fidings that inhaled sedatie drugs
without hepati or renal metabolism are safe for sedatin of premature or
anemic infants
