RESPIRATORY FUNCTIONAL CHANGES AFTER CAUDAL BLOCK IN PEDIATRIC SURGERY

<正>Alterations in blood-gas parameters before and after caudal block at different levels in 30 children undergoing operation were studied. No significant changes were noted after low caudal block. In high caudal block, hypoxemia may occur but can be successfully corrected by oxygen inhalation. It is suggested that routine use of oxygen inhalation is imperative in caudal anesthesia and that high level block should be avoided in children with poor ventilation.
