Clinical observation reveals sodium ion concentration affects lidocaine onset time in obstetric epidural blocks, suggesting implications for anesthesia practices.
Key Points
The fastest onset time of lidocaine in the epidural block was observed with normal saline dilution.
Group D with 1.5% normal saline had the shortest onset time at 3.59 minutes, compared to other groups.
Comparative analysis indicated significant differences in onset time, particularly between 1% saline and sterile water groups.
No adverse reactions were significantly reported across the four groups, indicating safety in the tested solutions.
