A&A practice
-
A 48-year-old woman with a history of cardiac surgery developed severe dyspnea and anxiety following right-sided supraclavicular nerve block for hand surgery. In this case, right phrenic nerve blockade from a supraclavicular block unmasked a subclinical hemidiaphragmatic paresis from phrenic nerve injury on the left, the latter likely due to previous cardiac surgery. When performing brachial plexus block at or above the clavicle, particularly for prior cardiothoracic surgical patients, anesthesiologists can easily, quickly, and inexpensively use point-of-care ultrasound to assess whether any degree of phrenic nerve dysfunction exists on the contralateral side, as patients may be asymptomatic at baseline.

Anesthetic Management of a Child With Rapid-Onset Dystonia-Parkinsonism (DYT12-ATP1A3): A Case Report.
Rapid-onset dystonia-parkinsonism also known as DYT12-ATP1A3 is an extremely rare neurological disease. Patients develop dystonia, bradykinesia, postural instability, dysarthria, and dysphagia. ⋯ We report the case of a 14-year-old patient diagnosed with rapid-onset dystonia-parkinsonism who was scheduled for injection of botulinum toxin in his upper limbs under general anesthesia. To our knowledge, there is no previous report about the anesthetic management of patients with rapid-onset dystonia-parkinsonism.

Obstructive hydrocephalus caused by brainstem compression is a life-threatening complication and usually occurs within 6 days, with peak on day 3 after onset of cerebellar infarction. We present a case of obstructive hydrocephalus that developed on day 8 in a patient with cerebellar infarction. ⋯ He was lucid postoperatively, but his consciousness was diminished on day 8 because of obstructive hydrocephalus. Cerebral edema due to cardiopulmonary bypass may contribute to delayed onset of obstructive hydrocephalus, especially in patients with large-sized cerebellar infarction.

The role of concurrent illness in coronavirus disease 2019 (COVID-19) is unknown. Patients with leukemia may display altered thromboinflammatory responses. We report a 53-year-old man presenting with acute leukemia and COVID-19 who developed thrombotic complications and acute respiratory distress syndrome. ⋯ The patient developed chemotherapy-induced neutropenia that may have protected his lungs from granulocyte-driven hyperinflammatory acute lung injury. However, neutropenia also alters viral clearing, potentially enabling ongoing viral propagation. This case depicts a precarious equilibrium between leukemia and COVID-19.

The sacroiliac joint (SIJ) is a common source of pain in patients with low back pain. Untreated pain from the SIJ can lead to prolonged discomfort and financial burden. ⋯ However, there is no clear description of SIJ cryoneurolysis in the published literature. In this report, we present 5 patients with SIJ-related pain and we describe the ultrasound-guided SIJ cryoneurolysis technique and its analgesic efficacy.
