Practice Guideline
Regional anaesthesia in patients on antithrombotic drugs: Joint ESAIC/ESRA guidelines.
Bleeding is a potential complication after neuraxial and peripheral nerve blocks. The risk is increased in patients on antiplatelet and anticoagulant drugs. This joint guideline from the European Society of Anaesthesiology and Intensive Care and the European Society of Regional Anaesthesia aims to provide an evidence-based set of recommendations and suggestions on how to reduce the risk of antithrombotic drug-induced haematoma formation related to the practice of regional anaesthesia and analgesia. ⋯ In patients taking antiplatelet or anticoagulant medications, practitioners must consider the bleeding risk both before and after nerve blockade and during insertion or removal of a catheter. Healthcare teams managing such patients must be aware of the risk and be competent in detecting and managing any possible haematomas.

Injectate spread in ultrasound-guided inferior alveolar nerve block: a cadaveric study.
Ultrasound-guided inferior alveolar nerve block (UGIANB) is a mandibular analgesic procedure in which local anesthetic is injected into the pterygomandibular space (PMS). Several studies have reported the clinical efficacy of UGIANB for mandibular surgeries; however, its effective range has never been investigated. We performed a cadaveric study to investigate the success rate of UGIANB injections and to determine whether injected dye could stain the mandibular nerve (MN) trunk and its branches. ⋯ UGIANB can administer anesthetic into the PMS with high accuracy. UGIANB injections reached the IAN, LN, and BNs, but did not reach the MN or ATNs located outside the PMS. The findings of this cadaveric study indicate that UGIANB can provide sufficient analgesia for mandibular surgeries.

Impact of ultrasound-guided erector spinae plane block on outcomes after lumbar spinal fusion: a retrospective propensity score matched study of 242 patients.
We evaluated the impact of bilateral ultrasound-guided erector spinae plane blocks on pain and opioid-related outcomes within a standardized care pathway for lumbar fusion. ⋯ Erector spinae plane blocks were associated with clinically irrelevant reductions in 24-hour opioid consumption and no improvement in pain scores after lumbar fusion. The routine use of these blocks in the setting of a comprehensive care pathway for lumbar fusion may not be warranted.

Case ReportsUltrasound-Guided Thoracic Paravertebral Block for Pulmonary Radiofrequency Ablation.
Surgical resection is the treatment of choice both for early-stage lung cancer and pulmonary metastatic disease. For patients with lung tumors who are not eligible for surgery, the minimally invasive modality of radiofrequency ablation (RFA) may be curative and, thus, should be considered. However, opinions regarding the optimal anesthetic technique for pulmonary RFA differ. ⋯ No patient required conversion from sedation to general anesthesia. There were no episodes of hemodynamic instability or desaturation (SaO2 ≤95%), and excessive sedation prevented patient collaboration in only one patient. In conclusion, ultrasound-guided single-injection TPVB is a safe and effective anesthetic technique for high-risk patients undergoing RFA for a primary lung tumor or lung metastases.
