Percutaneous peripheral nerve stimulation is used to provide analgesia for weeks or even months. While infection of any percutaneously implanted object is a concern, it is exceedingly rare for helically coiled leads, with a reported incidence of less than 1 infection for every 32,000 indwelling days. We now report an infected helically coiled lead requiring sedation for extraction and complicated by lead fracture during removal, leaving a remnant in situ. The infection was successfully treated with oral antibiotics. We speculate on the cause of this infection and propose steps to prevent this complication, including the avoidance of sling-to-lead insertion site overlap.

A 35-year-old female patient was scheduled for a left hemithyroidectomy. We performed bilateral cervical plexus blocks with ultrasound guidance for an awake thyroidectomy. Soon after the blocks, she developed a weak voice, which gradually progressed to complete aphonia. Due to her apprehension, general anesthesia was administered. After an uneventful surgery, the patient spontaneously regained her normal voice in the postoperative period. The case report describes a previously unreported complication of aphonia presumably due to bilateral recurrent laryngeal nerve blocks, which might have occurred from the infiltrated local anesthetic extravasating to the deeper planes through the cervical fascia.

A 13-year-old girl with a voltage-gated sodium channel mutation (SCN8A)-associated intractable epilepsy presented for bilateral mastectomy for painful juvenile fibroadenomatosis. Sodium channel mutations are more frequently diagnosed with continued advances in genetic testing. Understanding the effects of sodium channel mutations is important to provide safe anesthetic care to these patients. In this article, we discuss what is known regarding the physiology of SCN8A channels and the anesthetic considerations when caring for patients with an SCN8A mutation.

Patients with severe polyethylene glycol (PEG) allergies face broad challenges, especially when presenting to the hospital for surgery, as PEG is used often as an excipient in medications and in medical supplies. Although rare, this allergy is increasingly reported and likely underdiagnosed. We present a patient with known past anaphylactic reaction to PEG and a detailed account of her perioperative course. More broadly, we provide recommendations and resources for the safe management of similar patients with a severe PEG allergy.

In patients with bronchogenic cysts, spillage of cyst contents into the airway during anesthesia and surgery has been reported. Methods to prevent this complication are not definitive. A 21-year-old man with a large bronchogenic cyst was scheduled for cyst excision during which large quantities of purulent fluid spilled into the airway immediately after induction of anesthesia. This was due to unmasking of the existing communication between the cyst and the bronchial tree. Preoperative percutaneous drainage of the cyst contents, awake intubation, and lung isolation with a bronchial blocker before paralyzing and positioning the patient may be helpful.

We present a case of a pregnant patient with an unrepaired vein of Galen malformation (VGAM) and left ventricular (LV) dilation. Patients with VGAM lesions typically present during childhood with cardiac failure or developmental delay prompting embolization. Therefore, it is highly unusual for an adult to present with an unrepaired lesion.1 It poses challenges for obstetric and anesthetic management during pregnancy and delivery to reduce the risk of heart failure, arrhythmia, and intracranial hemorrhage. Our patient safely delivered a term neonate by cesarean delivery with neuraxial analgesia at a Level IV Maternal Care Center.

The management of postsurgical thrombosis in a medically complicated patient is often not straightforward. We describe a case of a congenital heart disease patient with multiple risk factors for thrombosis with a compromised limb immediately after heart transplant who received serial daily peripheral nerve blocks (PNBs) resulting in limb salvage. The analgesic effects of the blocks allowed for clinical progression and participation in rehabilitation therapy, and the vasodilatory effects of the blocks helped prevent a below the knee amputation (BKA) in this devitalized and congested extremity.

We present a case series to demonstrate proof-of-concept for the off-label use of an auricular neuromodulation device-originally developed to treat symptoms associated with opioid withdrawal-to instead provide analgesia and opioid-sparing following knee and hip arthroplasties. Within the recovery room, an auricular neuromodulation device (near-field stimulator system 2 [NSS-2] Bridge, Masimo) was applied to 5 patients. Average daily pain at rest and while moving was a median of 0 to 2 as measured on the 0 to 10 numeric rating scale, while median daily oxycodone use was 0 to 2.5 mg until device removal at home on postoperative day 5. One patient avoided opioid use entirely.

Neuronal intranuclear inclusion disease (NIID) is a progressive neurodegenerative disease with diverse clinical manifestations, including dementia and muscle weakness. We summarize anesthetic considerations in reporting general anesthesia for a 58-year-old man with bladder dysfunction and cerebellar ataxia who was diagnosed with NIID. The patient developed postinduction hypotension relevant to autonomic neuropathy. The potential risks, such as prolonged reaction to neuromuscular blocking agent, postoperative delirium, and worsening of NIID-related symptoms, were also considered. The responsiveness to anesthetics may vary widely from case t case. As the number of NIID cases increases, a better understanding of NIID is needed.
