Nerve block vs spinal morphine for hip surgery pain
Treatments studied
Part of Brain & nervous system, Pain clinical trials.
This trial compares two types of pain relief after a hip replacement: a nerve block (injecting numbing medicine near the hip) versus a small dose of morphine given through a spinal needle. It aims to find out which option works better with fewer side effects.
Summary written for real people, not researchers, by Clin2.

- You are 18 years or older
- Your general health is good enough to be rated ASA I, II, or III (fit to mildly limited)
- You are not allergic to any of these medicines: ropivacaine, paracetamol (Tylenol), ibuprofen (Advil), ketorolac (Toradol), morphine, ondansetron (Zofran), or dexamethasone (Decadron)
- You do not have a bleeding disorder or take blood thinners that cannot be stopped

This trial compares two pain-relief methods after hip replacement surgery: a nerve block (numbing the hip area) versus a numbing injection into the wound. The goal is to see which provides better pain control.
This trial tests whether a specific nerve block given during planned hip replacement surgery can reduce pain afterward. It may help you use less opioid pain medicine, but you must meet certain safety and medication criteria.
This trial compares three types of nerve blocks to find which provides the best pain relief after a hip replacement. It may help you have less pain and a smoother recovery.
This study compares two ways to manage pain after hip replacement surgery: one uses a spinal injection with morphine, and the other uses a nerve block near the hip. The nerve block may include an extra medicine called dexamethasone to see if it improves pain relief.
This study compares two ways to manage pain after hip replacement surgery: a nerve block near the hip (PENG block) versus a small dose of morphine given through the spinal anesthesia. The goal is to see which method helps patients recover better and have less pain in the first days after surgery.
This trial compares two ways to manage pain after hip replacement surgery: a targeted nerve block around the hip versus a small dose of morphine given through the spinal anesthesia. The goal is to see which method provides better pain relief with fewer side effects.
