RESUMO
One hundred and eighty-two case notes of patients delivered by the vacuum extractor over a 5-year period were reviewed. Fetal distress was a major indication for use. The main drawbacks were cervical lacerations and scalp trauma; the former contributed to postpartum hemorrhage, and the latter was a minor threat to fetal safety. The advantage of a relatively short application-delivery interval and the fact that it avoids delivery by cesarean section in some cases have made it a popular instrument in our labor ward.(AU)

Distortion of the parietal bones occurs whenever traction is applied via the vacuum extractor. This was confirmed experimentally by using a fresh mature stillborn foetus, and taking X-ray pictures of the skull with the three different of cap, and with different degrees of traction. (Summary)

Using a mature stillborn fetus, various sizes of caps and different degrees of traction of the Malmstrom vacuum extractor were employed and radiographs taken in order to demonstrate distortion of parietal bones. The danger of tearing the injunction of the falx and tentorium or rupture of the sagittal sinus were discussed. Further x-rays were taken with a Neville-Barnes forceps instead of the vacuum extractor (AU)
