Overview
Brief Summary
In this study, the investigator will examine the efficacy of Pericapsular nerve group (PENG) block in hip arthroplasty as a post-operative pain management technique, study the analgesia, opioid-sparing effects and motor-blocking effects of the PENG block
Detailed Description
PENG Block group (PG) will receive 0.5%Ropivacaine in 20 ml of saline. Sham Block group (SG) will receive 20 ml of saline Patient will be sedated with IV midazolam before nerve block. After peripheral nerve block ,general anesthesia will be conducted using sufentanyl, propofol and rocuronium for induction and propofol and sevoflurane for maintenance. Tests will be operated after procedure，and recorded up to 48 hours after surgery.

Outcomes
Primary Outcomes
Highest VAS score in recovery room
Time Frame: before recovery room discharge(up to 2 hours after surgery end)
Highest VAS score reported in recovery room,patient will be asked questions to measure the highest VAS score experienced in the recovery room before discharge. If the patient had a unexpected long stay at recovery room, the question will be asked at the time point "2 hours after surgery end"
Secondary Outcomes
- VAS at rest(day0 ,day1 ,day2)
- highest VAS at period(day0 ,day1 ,day2)
- quadriceps strength(day0 , day1 ,day2)
- total opioid consumption(up to 2 days after surgery)
- PONV rate(day0 ,day1 ,day2)
- Fall incident happened(up to 2 days after surgery)
- Nerve block range(day0 , before discharge from PACU(up to 2 hours after surgery end))
