Correlation of capilary and end-tidal carbon dioxide pressure during inhalation anaesthesia with a laryngeal mask compared to a face mask
The value of the laryngeal mask versus the face mask was
analized in two groups of thirty children each, in surgical procedures
shorter than sixty minutes. Four measurements of end-tidal (ET-CO
2<^*>)
carbon dioxide pressure were taken in both groups: five minutes after
the beginning of anesthesia, on surgical incision, fifteen minutes
after the operation had started, and finally after the withdrawing
of anesthesia, when the children had breathed 100% oxygen for five
minutes. On surgical incision the capillary acid-base status for
every child was also taken from finger. During anesthesia was also
measured noninvasive blood pressure, pulse and hemoglobin oxygen saturation.In each group we compared capillary and end-tidal carbon
dioxide pressure for every child. Between groups we compared the end-tidal
carbon dioxide values on incision. Statistical analysis showed that
values of ET-CO2<^*> are higher in patients with laryngeal mask
and lower in children with face mask and airway.The difference between capillary and end-tidal carbon dioxide
pressure is narrower in the laryngeal mask group and wider in the
