Chronic pain affects a significant amount of the population and represents a heavy personal and socioeconomic burden. Chronic pain mechanisms can be categorized as nociceptive, neuropathic, or nociplastic. Although mechanism-based pain treatment is optimal, different types of pain mechanisms may overlap in patients. Recently, the biopsychosocial model with the multidisciplinary pain management program is widely accepted as one of the most effective methods to assess and manage chronic pain. The treatment of chronic pain consists of a personalized, stepwise, and multimodal approach that includes pharmacotherapy, psychotherapy, integrative treatments, and interventional procedures. Somatic and peripheral nerve blocks for the treatment of chronic pain are often deferred. With the increasing use of ultrasound in pain medicine, newly defined interfascial plane blocks, which may be performed alone or as an adjuvant to multimodal management, have gained popularity. Adequate pain management can improve physical functioning, mental health and quality of life indicators, and reduce pain chronification. The aim of this current article is to perform a comprehensive and updated review of existing treatment options, particularly interfascial plane blocks in chronic pain syndromes.

Objectives: Genicular nerve radiofrequency procedures increasingly are being performed to treat chronic pain due to knee osteoarthritis. Targeting additional sensory nerves and improving target identification by using ultrasound guidance could improve treatment success. The aim of this study was to compare the effectiveness of targeting only the traditional genicular nerves versus targeting the traditional genicular nerves plus 2 additional sensory nerves in ultrasound-guided genicular nerve radiofrequency procedures in patients with chronic knee osteoarthritis. Methods: A total of 80 patients were randomized into 2 groups. Patients in the 3-nerve-targeted group received a genicular radiofrequency procedure in which the traditional genicular nerves were targeted: the superior lateral, superior medial, and inferior medial nerves. The 5-nerve-targeted group received a genicular radiofrequency procedure in which the recurrent fibular and infrapatellar branches of the saphenous nerve were targeted in addition to the traditional genicular nerves. The numeric rating scale, Short Form-36, Western Ontario and McMaster Universities Arthritis Index, Quantitative Analgesic Questionnaire, and patient satisfaction were evaluated before treatment, at week 1 after treatment, and at months 1, 3, and 6 after treatment. Results: Both techniques provided significant pain reduction and functional improvement up to 6 months after the procedure (P < .05). The 5-nerve-targeted group showed significant improvement with regard to the numeric rating scale, Western Ontario and McMaster Universities Arthritis Index total, and Short Form-36 score compared with the 3-nerve-targeted group at each follow-up point. No differences in the Quantitative Analgesic Questionnaire or patient satisfaction scores were observed between the groups. Conclusions: The ultrasound-guided 5-nerve-targeted technique is a safe method and a more effective therapeutic procedure than the traditional 3-nerve-targeted technique for chronic knee osteoarthritis.

Objective: Controversy exists around the world as experts disagree on what artificial intelligence will imply for humanity in the future. Medical experts are starting to share perspectives on artificial intelligence with ethical and legal concerns appearing to prevail. The purpose of this study was to determine how anesthesiology and reanimation specialists in Turkey perceive the use of artificial intelligence in ultrasound-guided regional anesthetic applications in terms of medical ethics and education, as well as their perspectives on potential ethical issues. Materials and Methods: This descriptive and cross-sectional survey was conducted across Turkey between July 1 and August 31. Data were collected through an online questionnaire distributed by national associations and social media platforms. The questionnaire included questions about the descriptive features of the participants and the possible ethical problems that may be encountered in the use of artificial intelligence in regional anesthesia and 20 statements that were requested to be evaluated. Results: The average age of the 285 anesthesiologists who took part in the study was 42.00 ± 7.51, 144 of them were male, the average years spent in the field was 10.95 ± 7.15 years, 59.3% were involved in resident training, and 74.7% habitually used ultrasound guidance regional anesthetic applications. Of the participants, 80% thought artificial intelligence would benefit patients, 86.7% thought it would benefit resident training, 81.4% thought it would benefit post-graduate medical education, and 80.7% thought it would decrease complications in practice. There will be no ethical issues if sonographic data are captured anonymously, according to 78.25%, while 67% are concerned about who will be held accountable for inaccuracies. Conclusion: The majority of anesthetists believe that using artificial intelligence in regional anesthetic applications will decrease complications. Although ethical concerns about privacy and data governance are low, participants do have ethical worries about “accountability for errors.” Cite this article as: Koçer Tulgar Y, Tulgar S, Güven Köse S, Köse HC, Çevik Nasırlıer G, Doğan M, Terence Thomas D.

Background/aim: Myofascial pain syndrome (MPS) is a common chronic pain syndrome that may affect quality of life, daily living activities, and psychological status. Ultrasound (US)-guided rhomboid intercostal block (RIB) is a recently defined plane block and used for chronic pain such as postmastectomy syndrome and MPS. Our aim was to evaluate the efficacy of US-guided RIB for the management of pain, quality of life, physical disability, and patient satisfaction in MPS. Materials and methods: In this prospective study, between February and March 2021, a total of 30 patients who applied with the diagnosis of MPS, were included. The patients received US-guided RIB. Pain intensity was evaluated using a numerical rating scale (NRS) at pretreatment, and just after the intervention, at day 1, and 1, 2, 4, and 6 weeks after the intervention. At pretreatment and 6 weeks after treatment, Short Form-36 Health Survey (SF-36) for health-related quality of life, Neck Disability Index (NDI), and patient satisfaction were evaluated. Results: There was a statistically significant decrease in average NRS immediately after treatment, at day 1 and week 1,2,4, and 6 compared to the pretreatment (p < 0.0001). The average SF-36 scores advanced at 6 weeks after treatment. There was a statistically significant reduction in mean NDI scores throughout the follow-up period (p < 0.001). Conclusion: Our study demonstrated that RIB had improved neck function, physical and mental quality of life, and patient satisfaction in MPS. Therefore, we think US-guided RIB could be an alternative treatment modality in patients suffering from MPS.
