Anesthetic Management Using Monitored Anesthesia Care and Paravertebral Block for Inguinal Hernia Repair

Abstract

Among anesthetic procedures, paravertebral block combined with sedation (PVB + MAC) has attracted attention because of its marked usefulness in terms of quality and side effects in comparison with conventional procedures. Anesthesia was managed using PVB + MAC in 8 patients undergoing inguinal hernia repair. PVB at the level of T10 to L1 was performed in 4 places under sedation with propofol. When an increase in body motion or heart rate in association with an increase in nociceptive stimulation was noted during surgery, local infiltration anesthesia in the operative field or additional intravenous fentanyl was administered. All patients were able to perform bed transfer without assistance immediately after surgery, and only one of the 8 patients required an analgesic within 12 hours after surgery. No patients had complications related to the block.
