Here at Duke University ASC, we treat some very challenging outpatient cases. Total joint replacements. Open inguinal hernia and rotator cuff repairs. Mastectomies. What's more, we treat high-risk outpatients, who go home complication-, PONV- and pain-free. How? Advanced regional anesthesia: single-injection and continuous-infusion peripheral nerve blocks. Here are five keys to our success.
Anesthesia- provider training
Most anesthesiology residency programs in the United States don't provide adequate training in peripheral nerve block techniques. However, good one-year regional anesthesia fellowship programs, regional anesthesia workshops and other courses are available. These programs are essential, as proficient providers must master three challenging areas:
|
Surgeon acceptance
How do you convince surgeons that regional anesthesia is in the best interest of patients, the surgical team and the facility alike? Clinical data speak volumes to surgeons, so start there. The No. 1 reason for unexpected hospital admission in the outpatient setting is pain; the second is PONV. Regional anesthesia addresses both. Our experience administering 30,000 blocks shows that regional anesthesia can provide excellent anesthesia as well as pain and PONV control and, consequently, high patient satisfaction.
With well-trained anesthesia personnel, regional anesthesia is a safer approach than general anesthesia, because it has minimal cardiopulmonary effects and reduces the metabolic and endocrine surgical stress response. It eliminates inhalational anesthesia-related PONV and can obviate inpatient stays.
You can also point out practical benefits. When the anesthesiologist administers regional anesthesia in a dedicated pre-op block area, there's no need to intubate and extubate patients intraoperatively and awaken them post-operatively. Regional anesthesia even reduces the number of post-op phone calls to surgeons, which are often pain control-related.
Dedicated pre-op block area
It's true that blocks take time to administer. A single-injection peripheral nerve block, for example, takes from five to 10 minutes. The solution? Create a pre-op block area if at all possible.
Unlike traditional hospital induction rooms, the block area is separate from the OR. This affords the anesthesiologist time to set up blocks, evaluate their effects and, if needed, re-administer anesthesia. The area must be equipped with monitoring equipment, a nerve stimulator, insulated needles, local and general anesthetics, intubation supplies, continuous infusion pumps, and a block cart containing airway emergency equipment and drugs to treat acute CNS and cardiac toxicity.
This room also affords patients privacy and offers an educational opportunity. We invite families into our block area to review treatments and teach post-op-care concepts.

RN Training
In the block area, nurses assist with sedation, patient positioning and peripheral nerve block placement. Our RNs operate the nerve stimulator and intermittently aspirate the syringe to ensure extravascular injection, allowing the anesthesia provider to hold the needle steady during injection. We also train them to help manage acute CNS and cardiovascular complications.
Intraoperatively, OR nurses assist with patient positioning and insensate limb protection.
In the PACU, nurses spend 10 to 15 miutes furthering the concepts taught in the block area, like multi-modal analgesia (NSAIDs, cryotherapy, acetaminophen), crutch-walking and insensate limb protection. For patients going home with pain pumps, nurses review signs and symptoms of local anesthetic toxicity and teach them how to turn local anesthetic infusions on and off, check catheter sites and remove catheters.
Staged implementation
Facilities that phase in advanced regional anesthesia programs do better than those trying to install complex programs at once. Initially, use the simplest single-injection peripheral nerve blocks (such as femoral and axillary nerve blocks) on low-risk patients who undergo relatively simple procedures. Once the team gets comfortable, employ techniques on sicker patients and for more complex procedures.
Eventually, you'll be ready for complex blocks like paravertebral, lumbar plexus, sciatic nerve, interscalene, and supraclavicular brachial plexus blocks. Continuous peripheral nerve blocks require advanced skills; attempt these only after mastering single-injection blocks.
Wave of the future
We're able to do regional anesthesia on 59 percent of our patients. Sometimes, patients lack the motivation, home support or comprehension to be good candidates, especially for continuous blocks. Other times, blocks fail to fully anesthetize the surgical area. Still, I believe regional anesthesia is the wave of the future. It provides the entire surgical team the keen sense of professional satisfaction that comes from serving patients compassionately and effectively.
