Objective To explore the causes and adverse effects of hypocarbia in newborns during mechanical ventilation. Methods Two hundred and forty-six newborns received assisted ventilation from Jan. 1994 to Dec. 2003 were retrospectively reviewed. Results The morbidity of hypocarbia was 14. 2%. It is common in preterm infants and the onset time of which were (31. 6?26. 9) hours after mechanical ventilation. The common primary disease was respiratory distress syndrome (RDS) (22. 6%). The mortality (32. 9%) and incidence of intracranial hemorrhage (20%) in hypocarbia cases were higher than those of the control group (7. 1 % and 5. 7%) (P
