ReviewComparative review of airway anesthesia and sedation methods for awake intubation.
Successful awake intubation hinges upon adequate airway anesthesia and sedation for patient comfort. This review will summarize relevant anatomy and regional anesthesia techniques to achieve airway anesthesia, and compare various airway anesthesia and sedation regimens. ⋯ Emerging evidence has indicated that nerve blocks for airway anesthesia may be superior to other methods of topicalization. Additionally, dexmedetomidine can be useful, both as monotherapy and with supplemental sedatives, to safely provide anxiolysis for the patient and increase success. However, it is crucial to note that the method of airway anesthesia and sedation regimen should be adapted to each patient and clinical situation, and knowledge of multiple techniques and sedation regimens can best equip anesthesiologists to do so.

Low back pain is among one of the most common presentations to the emergency department (ED). Regional anesthesia has recently gained traction as an option for analgesia in ED patients, especially in the wake of the opioid epidemic. ⋯ We describe a series of three cases of patients who presented to the ED with severe low back pain refractory to traditional therapy, successfully treated using lumbar ESPB. Lumbar ESPB may be an effective approach to achieving rapid analgesia in patients who present with low back pain who may otherwise be poor candidates for more traditional therapy, such as with opioids or NSAIDs, or who may have refractory pain despite use of these medications.

Meta AnalysisScalp Nerve Block, Local Anesthetic Infiltration, and Postoperative Pain After Craniotomy: A Systematic Review and Network Meta-analysis of Randomized Trials.
The most efficacious methods for controlling postoperative pain in craniotomy remain unknown. A systematic review and network meta-analysis were performed to compare the efficacies of different strategies of scalp nerve block (SNB), scalp infiltration (SI), and control in patients undergoing craniotomy. MEDLINE, Embase, and CENTRAL databases were searched for randomized controlled trials. ⋯ SNB using bupivacaine, lidocaine, and epinephrine combined, and SNB using ropivacaine, were likely the most efficacious methods for opioid consumption reduction (SUCRA, 88% and 80%, respectively). In summary, different methods of SNB / SI seem to have different efficacies after craniotomy. SNB using ropivacaine may be superior to other methods for postcraniotomy pain control; however, the overall quality of evidence was low.

ReviewCervical sympathectomy to treat cerebral vasospasm: a scoping review.
Delayed cerebral ischemia (DCI) is the second-leading cause of death and disability in patients with aneurysmal subarachnoid hemorrhage (aSAH), and is associated with cerebral arterial vasospasm (CAV). Current treatments for CAV are expensive, invasive, and have limited efficacy. Cervical sympathetic block (CSB) is an underappreciated, but potentially highly effective therapy for CAV. ⋯ This scoping review suggests that CSB may be a viable option for treatment and prevention of CAV/DCI in patients with aSAH, although the included studies were heterogeneous, mostly observational, and with a small sample size. Further research is needed to standardize the technique and prove its effectiveness to treat patients suffering of CAV/DCI after aSAH.
