A forceps rotation of 30degfrom left occiput anterior (OA) to OA with extraction of the fetus from +2 station would be described as which type of delivery?
In the late 1980s and early 1990s, the classic definitions of forceps deliveries were slightly altered to conform with obstetric reality and the need for realistic definitions of procedures vis-a-vis both medical and legal guidelines and standards. Outlet forceps delivery requires a visible scalp, the fetal skull on the pelvic floor, the sagittal suture in essentially OA position, and the fetal head on the perineum. A rotation can occur, but only up to 45deg. A low forceps delivery requires a station of at least +2 but not on the pelvic floor. Rotation can be more than 45deg. Mid-forceps delivery is from a station above +2, but with an engaged head. High forceps delivery, for which there are no modern indications, would reflect a head not engaged.
