Conclusion
By using a comparison of VAS scores and blood concentrations, those
findings from this study indicated that in continuous SAPB, 0.2%
ropivacaine had a similar analgesic effect as 0.375% ropivacaine and
was safer. However, the safety of drug concentration still needs further
study to be confirmed in larger study samples and using different
concentrations. In conclusion, ropivacaine with continuous SAPB provides
durable management of pain after thoracoscopic surgery as an alternative
for multimodal analgesic strategies.
