Nerve blocks are a way to help reduce pain and discomfort after surgery. Nerve blocks are performed by injecting numbing medication around the nerves that carry painful sensation from an arm or leg. In almost all pediatric patients nerve blocks are used together with general anesthesia for surgical procedures.
Depending on the age of the patient, nerve blocks can be performed while the patient is still awake or, more commonly, after the patient is asleep under general anesthesia.
The exact place where numbing medication is injected depends on where the surgical procedure is performed. For procedures on the shoulder, arm, elbow, or hand, injections may be made at the side of the neck, below or above the collar bone, or in the armpit. For procedures on the leg, knee, or foot, injections may be made in the groin, the buttocks, the thigh, or the back or side of the leg.
The anesthesiologist will discuss with you which nerve block will work best for your child and its benefits and risks.
Show AllNerve blocks can provide significant pain relief after surgery. They often substantially reduce the need for pain medications and pain medications related adverse effects such as vomiting, drowsiness and slow breathing. A nerve block may help your child getting up in a chair or walk around after surgery without being very uncomfortable.
One time injection (Single Shot) nerve blocks typically provide pain relief for 8-24 hours. Continuous nerve blocks with nerve catheters for major painful surgeries can provide pain relief for typically 2-3 days or as long as the nerve catheter is being used.
In general, complications are extremely rare with the sort of nerve blocks used at Cincinnati Children's Hospital Medical Center. However, possible complications include: less than perfect pain relief, bruises, discomfort where the needle was inserted and prolonged "pins-and-needles" sensation after the block wears off. Any type of long-lasting or permanent damage to nerves is extremely rare. Your anesthesiologist will discuss any potential problems and risks with you in detail.
The arm or leg where the nerve block has been performed will be so numb that no or only little pain will be felt. Therefore, it is important to watch that nothing harms it while it is still numb because no pain will be felt. Keep it away from heaters, fires, car doors and sharp objects.
When the numbness wears off, the pain or discomfort will increase. The amount of pain will vary depending on the operation.
The best way to keep your child comfortable is for him / her to take the medication that has been prescribed as soon as the pain begins. It is better to treat pain in advance than to catch up with it.
For certain operations, taking ibuprofen as soon as possible – even before the nerve block wears off – can decrease pain. This should be discussed with your child's doctor at the time of surgery.
It is possible that some nerve blocks may last longer than a day. However, if your child is not able to move the arm / leg or feel any sensation at all (touch, warm, cold, pain) for more than 24 hours after a nerve block was placed, please contact us by phone 513-636 7768.
For major and painful surgeries such as knee reconstruction, shoulder surgeries, often a continuous nerve catheter (thin plastic tube) placement is needed to provide extended pain relief for typically 2 to 3 days. Nerve catheters are placed by anesthesiologists in the operating room while children are under anesthesia and continuous infusion of numbing medication. Sometimes, children are discharged home with nerve catheters and numbing medication infusion pump to provide pain control at home for 2-3 days. For families living within 50 miles radius from the hospital in Ohio and Kentucky, daily home care nurse visits could be arranged to check on pain relief, nerve catheters and infusion pumps and for removal of nerve catheters. Acute Pain Service will actively manage children with nerve catheters.
If you have questions or concerns about your child's nerve block you can call the pain clinic at 513-636-7768 during clinic hours.
