Background and aims Hip surgery is commonly seen in aged patients. Anesthesia management for them is challenging; the selection of anesthesia method will have influence on the prognosis and life quality of patients. Ultrasound-guided T12 paravertebral block combined with L1-4 nerve roots block and sacral plexus block introduced in this paper. We have conducted this anesthesia on 4 aged patients who had accepted the total hip arthroplasty, all operations were finished successfully.

Methods Four aged patients were scheduled for total hip arthroplasty. All of them suffer from various kinds of systemic diseases, have a weak cardio-pulmonary function, and are subject to multiple complications and high risks during analgesia and operations. Ultrasound-guided T12 paravertebral block combined with L1-4 nerve roots block and sacral plexus block was successfully used for the surgery.

Results All operations were finished successfully, no opioid drugs or other sedation and analgesia drugs were used during the operations, and the patients had no discomfort.

Conclusions T12 paravertebral block combined with L1-4 nerve roots block and sacral plexus block can completely block the motion, feeling and sympathetic nerve of the hip joint, and provide a safe and effective anesthesia method for elderly patients who receive hip surgery.
