Language abilities of 8-year-old preterm children among the northern Finland 1-year birth cohort for 1985-1986.

The language abilities of 42 8-year-old preterm children with birth weight < 1,750 g from a 1-year birth cohort in northern Finland was studied with four different language tests. Control children from the same birth cohort matched individually with their preterm pairs for age, sex, twinship, mother's education, place of residence, birth order and family type were also studied. In psycholinguistic test, auditory skills did not differ between the preterm and the full-term groups.

QT interval of the ECG, heart rate and arterial pressure using propofol, methohexital or midazolam for induction of anaesthesia.

The effects of propofol 2 mg/kg, methohexital 2 mg/kg or midazolam 0.3 mg/kg were studied on the QT interval of the ECG corrected by the heart rate (QTc), heart rate and arterial pressure during induction of anaesthesia in 87 ASA class I-(II)-patients. The patients were randomly allocated to one of the three anaesthetic groups.
