Key result
Maximizing regional blocks is linked to ~57% lower general anaesthesia rates for Caesarean sections.
Why the study?
The study was motivated by the potential to reduce the general anaesthesia rate for Caesarean section by maximizing the use of regional blocks such as epidural and subarachnoid blocks.
Does the use of regional block (epidural and subarachnoid) reduce the need for general anaesthesia in patients undergoing Caesarean section?
Population
100 consecutive Caesarean section patients under general anaesthesia
Comparison
Maximum use of epidural and subarachnoid block versus current general anaesthesia practice
Design
Observational study of obstetric and anaesthetic circumstances

Does not support practice change; leaves open whether regional blocks can safely reduce general anesthesia rates in Caesarean sections.

Does the use of regional block (epidural and subarachnoid) reduce the need for general anaesthesia in patients undergoing Caesarean section?
Absolute Event Rate: 16% vs 37%
Maximizing the use of regional blocks can substantially reduce the rate of general anaesthesia for Caesarean sections.
Atara Davis (1982) conducted an observational in Caesarean section (n=100). Regional block (epidural and subarachnoid) vs. General anaesthesia was evaluated on General anaesthesia rate. Maximum use of epidural and subarachnoid blocks could potentially reduce the general anaesthesia rate for Caesarean sections from 37% to 16%.
