Ultrasound-Guided Regional Anesthesia for Pediatric Burn Reconstructive Surgery: A Prospective Study.

ABSTRACT: Pediatric patients face multiple reconstructive surgeries to reestablish function and aesthetics postburn injury. Often, the site of the harvested graft for these reconstructions is reported to be the most painful part of the procedure and a common reason for deferring these reconstructive procedures. This study in pediatric burn patients undergoing reconstructive procedures examined the analgesia response to local anesthetic infiltration versus either a single ultrasound-guided regional nerve block of the lateral femoral cutaneous nerve (LFCN) or a fascia iliaca compartment block with catheter placement and continuous infusion. Nineteen patients were randomized to one of three groups (infiltration, single-shot nerve block, or compartment block with catheter) and received intraoperative analgesia intervention. Postoperatively, visual analog scale pain scores were recorded-for pain at the donor site-every 4 hours while awake-for 48 hours. This nonparametric data was analyzed using a two-way ANOVA, Friedman's test, and Kruskal-Wallis test, with significance determined at P < 0.05. The analysis demonstrated that the patients in the regional anesthesia groups were significantly more comfortable over the 48 hour hospital course than the patients in the control group. The patients receiving a single-shot block of the LFCN were more comfortable on postoperative day (POD) 0 while the catheter patients were more comfortable on POD 1 and POD 2. There was not a statistically significant difference in opioid requirements in any group. Regional anesthetic block of the LFCN, with or without catheter placement, provides an improved postoperative experience for the pediatric patient undergoing reconstructive surgery with lateral/anterolateral skin graft versus local anesthesia infiltration of donor site. For optimal comfort throughout the postoperative period, an ultrasound-guided block with continuous catheter may be beneficial.

Project description:IntroductionDespite the inclusion of both diagnostic and procedural ultrasound and regional nerve blocks in the original Model of the Clinical Practice of Emergency Medicine (EM), there is no recommended standardized approach to the incorporation of ultrasound-guided regional anesthesia (UGRA) education in EM training.MethodsWe developed and implemented a structured curriculum for both EM residents and faculty to learn UGRA in a four-hour workshop. Each Regional Anesthesia Anatomy and Ultrasound Workshop was four hours in length and followed the same format. Focusing on common UGRA blocks, each workshop began with an anatomist-led cadaveric review of the relevant neuromusculoskeletal anatomy followed by a hands-on ultrasound scanning practice for the blocks led by an ultrasound fellowship-trained EM faculty member, fellow, or a postgraduate year (PGY)-4 resident who had previously participated in the workshop. Learners identified the relevant anatomy on point-of-care ultrasound and reviewed how to conduct the blocks. Learners were invited to complete an evaluation of the workshop with Likert-scale and open-ended questions.ResultsIn the 2020 academic year, six regional anesthesia anatomy and ultrasound workshops occurred for EM faculty (two sessions, N = 24) and EM residents (four sessions, N = 40, including a total of five PGY4s, 10 PGY3s, 12 PGY2s, and 13 PGY1s). Workshops were universally well-received by both faculty and residents. Survey results found that 100.0% of all responding participants indicated that they were "very satisfied" with the session. All were likely to recommend this session to a colleague and 95.08% of participants believed the session should become a required component of the EM curriculum.ConclusionThe use of UGRA is increasing, and and it critical in EM. An interdisciplinary approach in collaboration with anatomists on an interactive, nerve block workshop incorporating both gross anatomy review and hands-on scanning was shown to be well-received and desired by both EM faculty and residents.

Project description:BackgroundUltrasound-guided regional anesthesia (UGRA) is increasingly used by emergency physicians to provide safe and effective pain relief for patients. However, one of the factors limiting its widespread use is the lack of realistic models available for learners to train on. There are currently no inexpensive nerve block models available that are injectable and that closely mimic nerves, fascial planes, muscles, and other landmarks. Our aim is to create inexpensive, injectable nerve block models that can be used as effective medical training tools for UGRA.MethodsBy using a lean cut of pork such as pork loin, yarn soaked in ultrasound gel to simulate peripheral nerves, and drinking straws filled with gel to represent vascular structures, we created various nerve block models. Meat glue applied between sections of meat appears hyperechoic under ultrasound, thereby mimicking fascial planes and has the added benefit of helping to secure the components of the model together. Using these elements, we were able to create realistic peripheral nerve, fascia iliaca compartment, serratus anterior plane, and interscalene brachial plexus models.ResultsOne of the necessary skills in performing UGRA involves placing the needle tip along a fascial plane and visualizing hydrodissection of this plane with the local anesthetic. When meat glue (transglutaminase) is applied between layers of meat such as pork loin, the meat binds together and creates a hyperechoic line that mimics a fascial plane. When meat glue is applied to two apposing fascial layers naturally occurring on the meat, the fascial plane can be injected, and fluid can be seen hydrodissecting in this space. We created several nerve block models using meat glue and other components to mimic normal landmarks.ConclusionsWe have developed inexpensive and easily reproducible models that create the realistic appearance of tissues, nerves, and fascial planes under ultrasound. They can also accurately simulate hydrodissection of fluid in fascial planes. We hope these nerve block models will allow for the education in UGRA to be more widespread and accessible to learners from all specialties.
