Low-dose combined spinal-epidural anesthesia for a patient with a giant hiatal hernia who underwent urological surgery

A hiatal hernia refers to herniation of the abdominal organs through the esophageal hiatus of the diaphragm. A giant hiatal hernia affects digestive and cardiopulmonary function by compressing the organs. We report a patient who had low-dose combined spinal and epidural anesthesia (CSEA) for safe and effective anesthesia for conservative treatment of a giant hiatal hernia. An 84year-old woman who had a giant hiatal hernia was scheduled for ureteroscopic removal of a ureteral stone. CSEA was performed at the L4 to L5 lumbar interspace and an epidural catheter tip was placed 5 cm cephalad from the inserted level. The T12 block was checked after 10 minutes of intrathecal injection of 6 mg of 0.5% bupivacaine. The T10 block was checked after additional injection of 80 mg of 2% lidocaine through the epidural catheter. During anesthesia and surgery, the patient's vital signs remained stable and the operation was completed within 1 hour without any problems. In conclusion, low-dose CSEA may be safely used without any cardiopulmonary and gastrointestinal problems in patients with a giant hiatal hernia undergoing urological surgery.
