Vacuum Extractor-Chalmers MBICARJOURNAL anterior position. The more experienced practitioner may wish to extend the range of his intervention, but this should be limited to institutional conditions. There are many general practitioners in this country, including several of our former house-surgeons, who are using the instrument successfully. Further extension of this trend would help to reduce the dangers of forceps in unpractised hands and lead to improved figures for infant survival in the home, as we believe it has in the hospital.
SummaryThe Malmstr6m vacuum extractor has been employed for 400 deliveries at the Obstetric Unit, Ronkswood Hospital, Worcester, during 1948-63. In this time the incidence of vacuum extraction has increased progressively, while that of forceps delivery has fallen.Foetal mortality has fallen progressively, and recently there has been a fall in the incidence of caesarean section. It is suggested that both of these are due in part to the use of the vacuum extractor.Indications are described for the use of the instrument in both the first and the second stage of labour, and the results are detailed.The method has proved effective in cases of malrotation of the foetal head and of foetal distress, and results for both mother and foetus have been satisfactory. I am grateful to my colleague Mr. A. T. Marshall for permission to quote many of his cases included in the above series.
