An appraisal of vent house vacuum delivery
A retrospective analysis of Ventouse deliveries over a 10 year period at St. Charles Borromeo Hospital, Onitsha, Nigeria is presented. Between January 1991 and December 2000, 15802 deliveries were conducted, 572 were Ventouse deliveries, giving a Ventouse rate of 3.6%. The age range of the patients was 17-44 years, with a mean age of 28.2+ 5.5 years. The commonest indication for Ventouse delivery was prolonged second stage of labour 34.9% (195), followed by cephalopelvic disproportion in 10.6% (59), while the least indication was brow presentation in second stage of labour 1.3% (7). The maternal morbidity was mainly vaginal tear/laceration that occurred in 2.2% (12) of the patients. The success rate of Ventouse delivery was 91.6% (511). The corrected perinatal death rate was 9/1000 deliveries. Ventouse has a high success rate in prolonged second stage of labour, in first stage of labour and in fetal mal-positions. With the decline in the use of obstetric forceps and its teaching in most health institutions, ventouse becomes the instrument of first choice when assisted vaginal delivery is considered.
