Objective:
To determine whether 2006 Australian national guidance to delay elective caesarean section until 39 weeks' gestation would reduce the need for neonatal retrieval for respiratory compromise following elective caesarean.
Study Design:
This is a retrospective cohort study comparing infants born by elective caesarean section who required retrieval for respiratory distress in Western Australia before and after the national guidance (2003-2006 vs. 2008-2014).
Results:
The proportion of infants born by elective caesarean section who required retrieval for respiratory distress was reduced in the later cohort (0.77% (153/19 780) vs. 0.55% (227/40 875); p = 0.0012). The diagnosis of surfactant-deficient lung disease amongst retrieved infants was also reduced (26% (40/153) vs. 17.4% (40/227); p = 0.04).
Conclusion:
A reduction in the proportion of elective caesarean sections before 39 weeks in Western Australia was associated with a reduction in retrieval for respiratory compromise related to surfactant deficiency in infants born by elective caesarean section.

Retrieval
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

Western Blotting
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.
ER Retrieval Pathway
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...
