Abstract

In 1983, Brain introduced laryngeal mask as a new airway. Laryngeal mask bave many advantages of easy insertion without laryngoscope and muscle relaxants, minimal cardiovascular responses, decreasing damages of larynx and pharynx and also useful in difficult intubation or emergency airway care. We studied cardiovascular responses of parturients and Apgar score of neonates during tracheal intubation(Group I) and laryngeal mask insertion(Group II), After tracheal intubation or insertion of laryngeal mask, blood pressure(systolic, diastolic and mean) and heart rate were measured for 5 minutes at 1 minute interval. The results were as follows: 1) There were significant increase in systolic, diastolic, mean arterial pressure and heart rate in both groups, but degree of increase was less in laryngeal mask group. 2) The Apgar scores of the neonates did not differ significantly, 1 minute Apgar score was up 8 in both group. It is concluded that insertion of laryngeal mask is beneficial to parturients than use of laryngoscope and tracheal intubation to avoid harmful cardiovascular responses in the management of airway during cesarean section.
