Aim: To clarify clinical interactions between early hypocarbia, periventricular leukomalacia (PVL) and cerebral palsy of preterm infants. Methods: Serial measurements of PaCO2 using arterial blood samples at 3, 6, 12, 24 and 48 h of life were performed for 115 very-low-birthweight infants admitted between 1995 and 1999. Severe early hypocarbia. defined when at least two of five PaCO2 values showed 3.3 kPa or less, was observed in eight infants (hypocarbia group). Preterm PVL was diagnosed by serial ultrasonographic examinations and cranial magnetic resonance imaging. and subsequently classified into early-onset PVL diagnosed within 14 d, or late-onset PVL after 14 d. Perinatal risk factors for early hypocarbia were investigated from the mothers' records and interviews with obstetricians. Results: The average birthweight in the hypocarbia group was significantly smaller than that in the control group (p
