  • Comparison of Four Different Block Techniques for Postoperative Analgesia in Thoracotomy (2024) · Journal Of Cardıo-Vascular-Thoracıc Anaesthesıa And Intensıve Care Socıety · doi

    Our study had several limitations. First, it was a single- center study with a limited sample size, enrolling only 100 patients. Secondly, the analgesic effect was evaluated using a subjective indicator, as there was no objective indicator measuring the pain index. Third, some of the patients continued to experience pain for a long time after the operation. Therefore, the patients needed to be followed up for a longer period of time. However, this could help us better evaluate and compare the analgesic effects.

  • Ultrasound-Guided Peripheral Nerve Block as the Sole Anesthetic for Above-Knee Amputation in a Patient With Severe Cardiopulmonary Comorbidities (2026) · Cureus · doi

    The principal limitations of this report are its single-case design and the clinical rather than dermatomal assessment of block completeness. Postoperative analgesia required repeat block performance on day 1 as single-injection coverage resolved; prospective consideration of perineural catheter placement for continuous local anesthetic infusion may provide more durable analgesia in future cases of comparable complexity.

  • Effectiveness of Kinesio Taping and Proper Body Mechanics on Low Back Pain in Pregnancy (2026) · Jurnal Manajemen Informasi Kesehatan (Health Information Management) · doi

    The limitations of this study its quasi-experimental design without full randomization, which may have introduced selection bias. In addition, the study was conducted within a single healthcare service area, which limits the generalizability of the findings. Pain assessment relied on self-reported NRS scores, which may be influenced by subjective perception. The intervention duration was short-term, so long-term effects were not assessed.

  • Chronic postoperative inguinal pain after open inguinal hernioplasty: prevalence and clinical characteristics in a Mexican secondary care hospital (2026) · International Surgery Journal · doi

    Despite these limitations, this study provides valuable local epidemiological data regarding chronic postoperative inguinal pain in a Mexican secondary care setting, an area in which published evidence remains limited. Future multicenter studies with larger sample sizes and longer follow-up periods are warranted to better characterize risk factors associated with chronic postoperative inguinal pain and to evaluate strategies aimed at preventing this complication.

  • Factors influencing optimal postoperative pain management: a systematic scoping review (2026) · Frontiers in Pain Research · doi

    On the other hand, limited knowledge and misconceptions about pain, fear and negative perceptions of pain medication, expression challenges, individual and contextual limitations, knowledge and competency and collaboration challenges, professional constraints, organizational and policy deficiencies, resource and workforce constraints, and care coordination and continuity challenges, were key barriers to optimal postoperative pain management.

  • Factors influencing optimal postoperative pain management: a systematic scoping review (2026) · Frontiers in Pain Research · doi

    Postoperative pain management is a complex and multifaceted issue, requiring a comprehensive understanding of the factors influencing pain management. Healthcare systems and practitioners face significant challenges in addressing barriers to effective pain management, including resource constraints and communication challenges. Patients may experience fear and anxiety related to pain management, highlighting the need for patient-centered care and empowerment.

  • Adductor Canal Block vs Epidural Analgesia for Total Knee Arthroplasty: A Narrative Review of Analgesic Efficacy, Functional Recovery, and Safety (2026) · International Journal of Drug Delivery Technology · doi

    Postoperative pain management in TKA is challenging due to the significant pain and potential adverse effects of analgesic techniques. The heterogeneity among studies in terms of patient populations, surgical techniques, and analgesic protocols makes it difficult to compare outcomes. The need for early mobilization and functional recovery in TKA requires careful consideration of the safety profile and potential adverse effects of analgesic techniques.
