Case Reports
In-Home Intravenous Dexmedetomidine Infusion for Treatment of Dystonia: A Pediatric Case Report.
The off-label use of an intravenous dexmedetomidine infusion is an option for refractory symptoms in pediatric palliative care with a few published cases of in-home use, most limited to end-of-life care. After an intrathecal baclofen pump malfunction with meningitis and medication withdrawal, a 17-year-old adolescent with quadriparetic cerebral palsy and paroxysmal autonomic instability experienced relief of refractory pain and dystonia with an in-home intravenous dexmedetomidine infusion. His interdisciplinary care team collaborated to establish safety measures and adjust his home medication regimen to further improve quality of life well before his end of life.

Observational Study
A Case Series of Deep Subgluteal Block: A New Block Targeting the Missed Portion of the Hip for Analgesia After Total Hip Replacement.
The study aimed to evaluate the effectiveness of deep subgluteal block (DSGB) for pain relief after posterolateral-approached total hip replacement. The cadaver study and observational case series assessed the spread and outcomes of ultrasound-guided DSGB. ⋯ Anatomical dissection revealed effective spread of the injected substance. These findings suggest that DSGB could be a promising regional analgesic technique for postoperative pain management after posterolateral-approached total hip replacement.

Review Case Reports
Hereditary Angioedema in Pregnancy: A Case Report and Review of Obstetric Anesthesia Management.
Hereditary angioedema (HAE) is a rare disorder due to C1 esterase inhibitor deficiency, causing recurrent swelling. Pregnancy can exacerbate HAE due to estrogen fluctuations alongside peripartum stress and trauma. ⋯ Angioedema prevention involves timely anesthesia consultation, accessible emergency airway equipment, early neuraxial anesthesia, planned vaginal delivery, and 48 to 72 hours of close postpartum monitoring. Readily available C1-inhibitor and a multidisciplinary approach with these recommendations are crucial for peripartum management.

Dysphagia after anterior cervical spine surgery has a 5% to 15% incidence beyond 1-year postsurgery, often attributed to mechanical factors such as pharyngeal thickening and epiglottis inversion. Despite normal neurological examination and electromyography, nerve distortion related to stretching also remains a possibility in these patients and may cause allodynia resulting in odynophagia and dysphagia. Current treatment options for dysphagia after anterior cervical discectomy and fusion are limited to local intraoperative steroid injections and tracheal traction exercises. In our patient, a glossopharyngeal nerve block was effectively used to manage the glossopharyngeal allodynia, thereby reducing the odynophagia and dysphagia, ultimately enhancing oral tolerance.

Patients presenting with large ventral abdominal wall hernias require pretreatment with injection botulinum toxin A before surgery. Currently, multipoint and multilayered botulinum injection techniques are practiced. We are describing a new ultrasound-guided, 1-point, single interfascial plane botulinum toxin A injection technique for the closure of big hernial defects.
