[Monitoring ETCO(2) of the infants undergoing cleft lip repair under general anesthesia with autonomous respiration].
OBJECTIVE
To elevate the security of general anesthesia with autonomous respiration applied for infant cleft lip repair in infants.


METHODS
40 infants who received cleft lip repair were divided into two groups randomly, the autonomous respiration group (group A) and control respiration group (group C). The infants in group A underwent general anesthesia with autonomous respiration, while the infants in group C underwent general anesthesia with control respiration. The HR, SpO(2) and P(ET)CO(2) of the infants in two groups, and the breathing rate of the infants in group A on entering operating room (T(0)), 5 minutes after intramuscular injection of ketamine (T(1)), 5 minutes after inserting tracheal catheter (T(2)), 10 minutes after inserting tracheal catheter (T(3)), at the end of operation (T(4)) and 5 minutes after removing tracheal catheter(T(5)). SPSS11.5 software package was used to analyze data, and Student's t test was used for comparison between the two groups.


RESULTS
The P(ET)CO(2) of the infants in group A on T(2), T(3) and T(4) was significantly higher than that on T(0), and higher than that of the infants in group C (P<0.05). 70% infants in group A had paranormal ETCO(2) during operation. The SpO(2) of infants in the two groups was normal during operation, and there was no significant different between the two groups. The breathing rate of the infants in group A declined significantly on T(2) and T(3), and significantly lower than that on T0 (P<0.05). The HR of the infants in the two groups was smooth during operation.


CONCLUSIONS
General anesthesia with autonomous respiration could be used for cleft lip repair in infants, but it was imperative to monitor ETCO2 and SpO(2), and we should assist the infants to breath if needed.
