Progress in labour is dependant on the three variables: the powers, that is, efficiency of uterine contraction, the passenger: that is, the fetus with respect to its size, presentation and positions and the passages: that is uterus, cervix and the bony pelvis.
Abnormalities in one or more of these factors can slow down the progress of labor. In this unit we are going to examine these abnormal presentations and their effect on the course of labour.
At the end of these lectures you will be able to
· Outline the types of abnormal presentation and positions.
· Identify the causes.
· Make accurate diagnosis
· Manage the conditions effectively.
· Describe the possible outcomes.
