Periventricular-intraventricular hemorrhage (PV-IVH)is one of the most important neurologic lesion of the low birth weight infants.
Serial neurosonographic exeaminations were performed in 113 low birth weight infants who were admitted to the neonatal intensive care unit of Presbyterian Medical Center from November 1, 1990to July 31, 1991.
@ES The results were summarized as follows:
@EN 1) The incidence of PV-IVH in the study was 54%
2) According to Papile's grading system of PV-IVH, grade I was 32.8%, grade II was 45.9%, grade IIIwas 11.5% and grade IV was 9.8%.
3) The onset of PV-IVH was within the first 7 days of life in 82%.
4) Poor activity, apnea, bradycardia and hypotension were statistically significant clinical findings associated with PV-IVH(P<0.05).
5) The risk factors associated with PV-IVH were gestational age, birth weight, hyaling membrane disease, patent ductus arteriosus and artifical ventilation.
6) The mortality of PV-IVH was 0% for grade I, 10.7% for grade II,42.9% for grade III and 83.3% for gradeⅣ
