[Expanded indications for cesarean section for low birth weight infants].
Retrospective investigations on 849 low birth weight infants between 1,001 and 2,500 gm born from 1966 to 1982 were done. The infants were divided into three groups with birth weights from 1,001 to 1,500 gm, from 1,501 to 2,000 gm, and 2,001 to 2,500 gm. The results of spontaneous delivery, delivery with manual assistance and caesarian section were compared. In the weight group 1,001 to 1,500 gm (14%), the perinatal mortality was 32%. In caesarian sections, the perinatal mortality was 19%, in spontaneous deliveries the perinatal mortality was 32% and in delivery with manual assistance the perinatal mortality was 45%. In the second weight group of 1,501 to 2,000 gm the perinatal mortality was 14.8%. Spontaneous delivery had a perinatal mortality of 16%, manual assistance a perinatal mortality of 14% and caesarian section a perinatal mortality of 10%. In both birth weight groups of 1,001 to 1,500 gm and 1,001 to 2,000 gm, the infants born by caesarian section had a significantly improved prognosis. Therefore, we recommend caesarian section in these weight groups for all breech presentations. In vertex presentations, caesarian sections are indicated when additional risk factors especially prolonged labour are apparent. In the third weight group between 2,001 and 2,500 gm the overall perinatal mortality was 4.9%. The spontaneously delivered infants have a mortality of 4.1%. Manual assistance was associated with a perinatal mortality of 5.9%. Caesarian section had a perinatal mortality of 11%.(ABSTRACT TRUNCATED AT 250 WORDS)
