Measure
QLB Block + Standard of Care
Patients will receive either a spinal (4cc Mepivacaine) or combined spinal epidural anesthetic (dose up 50 5 cc 2% lidocaine) with IV sedation. Intraoperative anti-emetics will consist of IV ondansetron and IV dexamethasone. Intra-operative analgesics will be IV fentanyl, IV acetaminophen, IV ketorolac, and IV ketamine. No Block will be given. Patients will receive a single shot anterior QLB (30cc 0.5% Bupivacaine with 2mg preservative free dexamethasone). Bupivacaine + dexamethasone: Anesthetic that will help treat pain and sensation after hip arthroscopy Ultrasound: Ultrasound will help guide the anesthesiologist in performing the nerve block
