Instrumental (operative) vaginal deliveries: vacuum extraction compared with forceps delivery at Ilorin University Teaching Hospital, Nigeria.
In a four-year period (1984 to 1987) a total of 141 Nigerian women who had instrumental vaginal deliveries at term in the Obstetric unit of University of Ilorin Teaching Hospital, Ilorin, were studied. Out of this number 79 had forceps delivery while 62 had vacuum extraction. The forceps delivery rate had fluctuated between 0.11% and 0.46% while the vacuum extraction rate had steadily increased from 0.08% to 0.39% (Table 1) in our unit over the 4-year period. With the exception of fetal distress, there were no significant differences found in the indications for forceps delivery and vacuum extraction. The preapplication station, position and cervical dilatation differ in both groups (Table 4). There was less maternal trauma in vacuum extraction than forceps (Table 5). The vacuum extraction was more associated with cephalhaematoma and neonatal jaundice but less with neonatal mortality compared with forceps (Table 7). Vacuum extraction had gradually assumed more prominence as an alternative to midforceps delivery in our unit in the study period. There was no maternal mortality in the two groups.
