Station
Level of descent of the presenting part relative to the pelvic brim or symphysis on abdominal palpation. Or to the ischial spines on vaginal examination.
42
Lie
Relationship between long axis of the feotus and long axis of the uterus, e.g. longitudinal, oblique, transverse
43
Position
Relationship of a defined area on the presenting part (the 'denominator') to the mother's pelvis. In a cephalic presentation, the denominator is the occiput, thus the foetal position is described as occipito-anterior (OA), occipio-posterior (OP), left or right occipito-transverse (L/ROT). In a breech presentation, the denominator is the sacrum (SA, SP, ST)
44
Presentation
The part of the fetus which is presenting e.g. vertex, breech
45
Asynclitism

47
Cervical Incompetence
Painless cervical dilatation in the 2nd trimester causing preterm labour
48
Cord Prolapse
Cord is alongside or below the presenting part in the presence of ruptured membranes
49
Episiotomy

50
Third Degree Tear
