Special Issue Information

Dear Colleagues,

This Special Issue delves into the latest trends in regional anesthesia and pain management, emphasizing innovations within the biomedical field. Regional analgesic techniques have emerged as a major aspect of the Enhanced Recovery After Surgery (ERAS) protocol. Notably, the integration of AI into the planning and execution of the regional technique promises to further enhance outcomes by optimizing nerve block placement and individualizing treatment plans. Furthermore, percutaneous microlead implantation for continuous peripheral nerve stimulation has been developed in order to preferentially affect the sensory fibers (SPRint PNS system) with an adjustable period of action. In addition to its civilian applications, such technical advancements have gained significant attention in military medicine. To save the lives of patients with ongoing traumatic bleeding requiring amputation, regional anesthesia exhibits unique value in the context of modern conflict and warfare. In war zones where traditional general anesthesia equipment may be unavailable, ultrasound- or nerve stimulator-guided peripheral nerve blocks offer a practical strategy for performing surgeries without anesthesia machines and the shock induced by neuraxial block during bleeding. Furthermore, a curriculum is now required to train anesthesiologists in rescuing the lives of military trauma patients. For transporting military trauma patients, catheterization for continuous infusion is more adequate, either via neuraxial or peripheral perineural routes. While TEA procedures can be technically challenging, innovations such as EpiFaith or CompuFlo have emerged to enhance safety and efficacy.

To effectively manage chronic pain, a multimodal approach that incorporates various treatment strategies is often necessary. In addition to the advancement of regenerative and nutritional pain medicine, minimally invasive interventional techniques, such as transarterial microembolization or joint denervation, have emerged as promising techniques for addressing pain conditions in which traditional pain management strategies have proven limited in their effectiveness. These innovative techniques offer a targeted and potentially transformative approach to managing complex pain conditions.

This Special Issue welcomes the submission of original research papers, communication, opinion and comprehensive reviews that address these emerging trends, including the latest clinical applications and future directions.

Abstract
Background: Multimodal analgesia, combining adductor canal block (ACB) and local infiltration analgesia (LIA), is commonly used for pain control after total knee arthroplasty (TKA). However, ACB alone may not fully cover the anteromedial knee, a region extensively disrupted by TKA. Recent studies [...] Read more.
Background: Multimodal analgesia, combining adductor canal block (ACB) and local infiltration analgesia (LIA), is commonly used for pain control after total knee arthroplasty (TKA). However, ACB alone may not fully cover the anteromedial knee, a region extensively disrupted by TKA. Recent studies suggest that blocking branches of the anterior femoral cutaneous nerve (AFCN) could enhance analgesia, but targeted AFCN blocks are technically challenging. We evaluated supra-sartorial subcutaneous infiltration (SSSI) at the femoral triangle apex as a simpler alternative to AFCN blocks. Methods: We retrospectively reviewed 19 patients undergoing TKA with a standardized multimodal analgesic protocol, including intraoperative LIA limited to posterior capsule (PC-LIA), postoperative SSSI, and delayed intermittent ACB via catheter. SSSI involved infiltrating 20 mL of 0.3% ropivacaine into the subcutaneous plane above the sartorius muscle at the level of femoral triangle apex. Pain was assessed using Numerical Rating Scale (NRS) scores at rest and during movement at 9:00 PM on postoperative day 0 (POD 0) and 9:00 AM on POD 1, with scheduled ACB doses administered at the time of NRS pain score assessments. Rescue ACB boluses were given for intolerable pain before the first scheduled dose. Results: Eleven patients (58%) required no rescue analgesia before the first scheduled ACB, maintaining NRS scores ≤ 4 at rest and with movement for a minimum of 575–785 min post-spinal anesthesia. Eight patients needed rescue ACB, with variable pain relief. Conclusions: SSSI, when combined with PC-LIA, provided clinically meaningful analgesia in 58% of our patient cohort following TKA, though the variability observed suggests limited consistency. As a practical alternative to targeted AFCN blocks, SSSI could potentially complement ACB in multimodal pain management, but its efficacy remains uncertain due to the retrospective, non-controlled study design without a comparator group. Further investigation through prospective randomized controlled trials is warranted to validate these preliminary findings. Full article
