Introduction: Local infiltration of knee joint in arthroplasty, provide postoperative analgesia and preserves motor power of quadriceps, which helps in early mobilisation, as compared to femoral nerve block which paralyses vastus medialis.
Aim: To compare the quality of postoperative analgesia provided by femoral nerve block and local infiltration in unilateral Total Knee Arthroplasty (TKA).
Materials And Methods: A prospective study was conducted on 60 patients (25-65 years) of ASA I and II, which were randomly(using random number table) divided into two groups - Group 1-femoral nerve block (FNB) and Group 2-Local Infiltration Analgesia (LIA). Patients with chronic pain and on opioids were excluded. Numeric rating scale (primary objective), sedation score, nausea vomiting score and motor power were analysed. The results were analysed by parametric and nonparametric tests using SPSS software version 22. p<0.05 was considered significant.
Results: Pain relief was better in FNB Group (p-value <0.001) with less fentanyl demand (p-value <0.001), low sedation score (0.013, 0.179, 0.018, 0.129, 0.287, 0.432) but associated with low muscle power grading (<0.001).
Conclusion: FNB has better pain relief than LIA Group but range of motion was reduced in FNB Group grossly, effect on mobilisation remained comparable in both group.

Rhomboid Intercostal and Subserratus Plane Block for Acute Pain Management after Abdominal Surgeries: A Narrative Review.
Curr Pain Headache Rep

Department of Anesthesiology, Perioperative, and Pain Medicine, Harvard Medical School, Brigham and Women's Hospital, Boston, MA, USA.
Purpose Of Review: The rhomboid intercostal and subserratus plane (RISS) block is an effective, safer alternative for managing postoperative acute pain following abdominal surgeries. The RISS block offers several advantages over traditional approaches, including reduced incidence of puncture-related complications, lower rates of systemic opioid consumption, and more consistent analgesic coverage of lower thoracic dermatomes.
Recent Findings: Despite a favorable safety profile, the RISS block carries potential risks, such as pneumothorax and local anesthetic systemic toxicity, particularly when long-acting anesthetics such as bupivacaine or ropivacaine are used.

Total knee arthroplasty is a life-changing surgical procedure that is associated with a high incidence of severe postoperative pain. Key to enhancing recovery after surgery is effective analgesia and early mobilisation. Innovations in motor-sparing regional anaesthesia techniques that have improved recovery include targeted surgical local infiltration analgesia, adductor canal blockade, genicular nerve blocks, and the infiltration between the popliteal artery and posterior capsule of the knee (iPACK) block.

Background: The role of local infiltration anesthesia (LIA) in knee surgery is significant. LIA can be more potent than a nerve block, but without the downsides. A wide range of agents are used for LIA, including some off-label medications such as dexmedetomidine and ropivacaine.

Interscalene blocks, commonly used for shoulder surgery analgesia, often cause transient phrenic nerve palsy, leading to hemi-diaphragmatic paresis. This complication is particularly problematic in patients with pulmonary comorbidities and has been extensively investigated. However, its impact on patients with Fontan physiology remains less understood with limited representation in the literature.

Department of Anesthesia and Critical Care, Hanoi Medical University, Hanoi, Vietnam.
Background: Fractures of the long bones in the lower limbs are injuries that cause severe to extremely severe pain, posing risks to the patient's circulation, respiration, and even life. Pain management for patients with lower limb long bone fractures in the emergency department is critically important.
Objective: This study aimed to evaluate the feasibility of ultrasound-guided femoral and sciatic nerve blocks in patients with lower limb long bone fractures in the emergency department (ED).
