Collection and usage attributes

Comments:Prostaglandin is listed as a method of augmentation in the data domain. Advice from the Royal Australian and New Zealand College of Obstetricians and Gynaecologists and the manufacturer indicates that vaginal prostaglandin use is not recommended or supported as a method of augmentation of labour as it may significantly increase the risk of uterine hyperstimulation. In spite of this, the method is being used and it is considered important to monitor its use for augmentation.

Collection and usage attributes

Guide for use:

More than one method of augmentation can be recorded, except where 0=none applies.

Collection units need to edit carefully the use of prostaglandins as an augmentation method. Results from checking records have shown that either the onset of labour was incorrect or that the augmentation method was incorrectly selected.


Type of augmentation determines the progress and duration of labour and may influence the method of delivery and the health status of the baby at birth.
