A Case Report of Paravertebral Block: A Safe Alternative for Microdiscectomy in a Pregnant Patient.

Nonobstetric surgery during pregnancy is common. Administration of safe anesthesia to a pregnant patient, while minimizing its side effects on the fetus, is a major challenge for the anesthesiologist. Both general anesthesia and central neuraxial block are associated with risks during early pregnancy. Regional nerve blocks are being explored as possible alternatives whenever feasible. This report emphasizes the usefulness of ultrasound-guided, modified bilateral paravertebral block in a first-trimester pregnant patient undergoing microdiscectomy for cauda equina syndrome.
