Acute respiratory distress syndrome (ARDS) constitutes a high burden for intensive care units. Although several methods are proposed to monitor aeration in ARDS, availability, costs, simplicity, and hazards (eg, ionizing radiation) limit the use of many of them at patients' bedsides. Given the widespread use of lung ultrasonography (US) in intensive care units, research is growing regarding its use to monitor aeration in patients with ARDS. ⋯ Additionally, an improvement in aeration by lung US does not always correlate with an increase in oxygenation. Lung US can be considered the main imaging method for monitoring aeration in ARDS, but in view of its limitations, it should not be used in isolation. Further studies are needed to validate lung US in large ARDS populations.

The posterior antebrachial cutaneous nerve branches from the radial nerve proximal to the elbow and supplies sensation to the posterior aspect of the forearm. With a high-frequency linear transducer, the posterior antebrachial cutaneous nerve was identified in 8 healthy volunteers. ⋯ In each participant, the block was successful, and neither incidental blocks of other nerves nor any other complications were observed. These results demonstrate that the posterior antebrachial cutaneous nerve can be blocked to provide anesthesia or analgesia to the posterior forearm.
