Continuous spinal anesthesia versus single small dose bupivacaine–fentanyl spinal anesthesia in high risk elderly patients: A randomized controlled trial

Conclusion CSA provided fewer episodes of hypotension and no severe hypotension versus SD 7.5mg bupivacaine. CSA offers the added advantage of the ability to titrate dose of local anesthetic as needed while maintaining hemodynamic stability.
