Overview
Brief Summary
Total hip arthroplasty (THA) is one of the most successful orthopedic procedures to effectively relieve pain and restore function in patients with hip osteoarthritis, osteonecrosis of femoral head and hip fracture.The Lumbar Plexus Block (LPB) is currently used as the standard regional anesthesia technique to provide postoperative pain management after THA. The lumbar plexus (LP) originates from T12 to L5. In general, multiple-needle nerve blockade procedure is needed to block different branches of LP. Therefore, we need more time to finish the regional anethesia procedure and it's not easy for an inexperienced anesthesiologist to master the technique absolutely. In addition, multiple injections will increase the discomfort of the patients. We aim to investigate the effects of lumbar plexus combined with quadratus lumborum block using single-needle technique with Shamrock method as an alternative regional anesthesia.

Outcomes
Primary Outcomes
sensory block assessment
Time Frame: 30 minutes after nerve block procedure
The sensory block will be assessed by cold alcohol swab and pinprick at lateral, anterior and medial areas of thigh and postero-lateral area of gluteus using a 0 to 2 point scale. 0= no block, patients can feel cold; 1= analgesic block, patient can feel touch but not cold; 2= anesthetic block, patient cannot feel cold or touch.
Secondary Outcomes
- postoperative static pain at timepoint 2(at 6 hours after surgery)
- postoperative static pain at timepoint 1(at 30mins after the patient recover from general anesthesia)
- postoperative static pain at timepoint 3(at 12 hours after surgery)
- Cumulative doses of intraoperative vasoactive medications(during the operation)
- postoperative static pain at timepoint 4(at 24 hours after surgery)
- Incidence of block related adverse events(within 24hours after nerve block procedure)
- Performance time of block(During nerve block procedure)
- intraoperative sufentanil dosage(during the operation)
