Believe it or not, a surgeon first got us thinking about continuous peripheral nerve blocks. That's right, a surgeon. Surgeons are notoriously intolerant when regional anesthesia backs up their schedule. Yet there was orthopedic surgeon Paul Switlyk, MD, the shoulder revision specialist in our area, asking us a couple years ago to look into offering continuous blocks at our center to help alleviate the lasting pain patients were feeling after more complicated shoulder procedures, which sometimes had them returning to our facility to be re-blocked. We did our first continuous nerve block in October 2009 and, yes, the process at first added a considerable amount of time to our room turnovers. A year and a half and more than 70 blocks later, we couldn't be happier with the results, from both a patient satisfaction and a profitability standpoint. Here's how we made it work.
Equipment and supply needs
Assuming that you already do single-shot regional anesthesia at your facility, there are very few additional supplies and equipment that you need for continuous nerve blocks aside from the pain pumps themselves, which get hooked up to the catheter that's already been placed during the initial block administration in pre-op.
When we first embarked upon this program in 2009, there were very few companies offering pain pumps for continuous nerve blocks, but the options have expanded since then. As with any product, have the reps bring in the pumps and explain how they work, then conduct a trial to see how easy they are to program and operate. Pay particular attention to how patient-friendly the pump is to operate. You want the patient control aspect of the pain pump to be as simple as possible.
One logistical decision you'll need to make is whether to go with pre-filled pumps or have your anesthesia providers or staff fill them on site. We went with the latter option: Our anesthesia providers, who are the ones administering the blocks and following up with patients once they go home, fill the pumps in the OR immediately after the case and then hook them up to patients before they're wheeled into recovery.
All the other supplies and equipment you'll need for continuous blocks are the same as you'd use for regular one-shot blocks: nerve stimulator, needles and medication mix. Continuous blocks require a catheter and the pump in addition to the single-shot block supplies. One piece of equipment that's not considered necessary but that we've found to be a tremendous asset to our regional anesthesia program is an ultrasound machine. We started doing regional anesthesia and continuous blocks before we got an ultrasound machine. Once we got one and our anesthesia providers became proficient in using it for block placement, it really streamlined the process and shaved precious minutes off our block times.
Although it was a surgeon who initially raised the idea of offering continuous nerve blocks at our facility, the anesthesia providers and nursing staff ultimately brought this idea to fruition. Expect turnover delays during the implementation period, as there's definitely a learning curve involved. Here are some tips for a smooth implementation:
Who Should Get Continuous Blocks? |
Continuous blocks aren't for everyone, so a conservative approach is best when introducing this option for your patients. Out of the 419 shoulder surgeries we hosted in 2010, 67 involved a continuous block, for a rate of about 16%. A single-shot block that lasts about 24 hours, followed by opioid therapy once patients can start eating and being active, works great most of the time. Most patients would prefer not to have that feeling of a numb, heavy extremity for 3 straight days if they can avoid it. And for procedures on the hips and knees, blocking the site for too long limits the patient's ability to be mobile, which can delay the healing process and increase the risk of falls at home. But some procedures will leave patients with lasting pain for days that opioids alone just can't tackle. That's when continuous nerve blocks, infused via a pain pump sent home with the patient, can come in handy. Limit the option of continuous nerve blocks to patients undergoing the more complicated procedures: rotator cuff revision, shoulder reconstruction, capsulorrhaphy, Latarjet procedure and fracture repair. Outside of orthopedic surgery, continuous blocks are frequently used to alleviate abdominal pain after plastic surgery (we don't host those procedures at our center). — Kecia Rardin, RN, CNOR, CASC, and Deborah Spain, RN, BSN, CNOR |
Continuous results
The 2 biggest benefits we've realized from our continuous nerve block program actually go hand-in-hand. First and foremost, the patients who come to our center for some of the most complicated procedures we host are experiencing more comfort and pain relief for longer periods of time after they go home. This prevents late-night phone calls from patients in pain and repeat visits from patients needing additional interventions to control post-op pain days after the procedure. This increased patient satisfaction meant we were able to bring more complicated shoulder procedures to our center last year. Dr. Switlyk's net revenue into our center increased along with the number of complicated surgeries he brought here. (For more on the financial aspects, see "Continuous Nerve Blocks in Dollars and Cents" on p. 46.)
Finally, if you strive to be one of the top orthopedic surgery facilities in your area, you've got to have the top pain management processes in place. After all, it doesn't matter how great a surgery you perform. If patients are going home uncomfortable, that's bad for your facility. As one of the largest orthopedic surgery centers in our community, we strive to be at the forefront of technology. Offering continuous peripheral nerve blocks is just one part of that larger effort to be on the cutting edge.
