Anesthetic Management and Neuromonitoring in a Patient with Very Long-Chain Acyl-Coenzyme A Dehydrogenase Deficiency Undergoing Scoliosis Surgery: A Case Report and Review of Literature

Patients with very long-chain acyl-CoA dehydrogenase deficiency (VLCADD) are prone to hypoglycemia and clinical decompensation when metabolic demands of the body are not met. We present a pediatric patient with VLCADD who underwent a posterior spinal fusion for scoliosis requiring intraoperative neurophysiology monitoring. Challenges included minimization of perioperative metabolic stressors and careful selection of anesthetic agents since propofol-based total intravenous anesthesia (TIVA) was contraindicated due to its high fatty acid content. This case is unique due to the sequential use of inhaled anesthetics after TIVA to allow for a rapid wakeup and immediate postoperative physical exam. Additionally, intraoperative neuromonitoring in the setting of VLCADD has not been reported in the literature. With communication among anesthesia, surgery, and neuromonitoring teams before and during the operation, the patient successfully underwent a major surgery without complications. This trial is registered with NCT03808077.

Migration of an Inferior Vena Cava Tumor Thrombus during Renal Cell Carcinoma Resection

Approximately 4%–10% of patients with renal cell carcinoma (RCC) have tumoral vascular invasion with resultant thrombi in the renal vein and in the inferior vena cava (IVC). The authors describe an interesting case of IVC tumor thrombus that migrated to the right cardiac chambers during RCC resection. The diagnosis was made by intraoperative transesophageal echocardiography (TEE), which revealed the presence of a free-floating thrombus between the right atrium (RA) and right ventricle (RV). The patient required an urgent sternotomy with cardiopulmonary bypass (CPB) for atrial thrombus removal prior to the completion of the nephrectomy. The patient made a full recovery and was discharged to a rehabilitation facility. These findings illustrate the importance of intraoperative TEE monitoring during nephrectomy and IVC thrombectomy. In this case, TEE allowed for the diagnosis of an unexpected complication necessitating prompt cardiac surgical management.

Adequate Oxygenation State Maintained during Electroconvulsive Therapy in Nonobese Patients Using the Oxygen Reserve Index: A Pilot Study

Some controversial reports have observed oxygen desaturation (defined as percutaneous oxygen saturation (SpO2) < 90%) during electroconvulsive therapy (ECT). The purpose of this pilot study was to examine oxygenation states in eight patients during ECT. In addition to the usual hemodynamic monitors and pulse oximeter, the oxygen reserve index (ORi) was monitored using a pulse oximeter. Patients received either no preoxygenation or preoxygenation with 100% oxygen via a tight-fitting mask for 1 or 3 min before induction of anesthesia. ORi increased after preoxygenation. ORi differed significantly between 3 min of preoxygenation and the other two methods before restarting mask ventilation. SpO2 was significantly increased with all methods before stopping manual mask ventilation or before restarting manual mask ventilation compared with that before preoxygenation. No oxygen desaturation was observed at any time with any treatment methods. In nonobese patients, the adequate oxygenation state as shown by SpO2 and ORi was maintained during ECT even without preoxygenation.

Ultrasound-Assisted Management for Tracheal Intubation in the Patient with Tracheal Diverticulum

Tracheal diverticulum (TD) is a rare disease. Due to the worldwide pandemic of COVID-19, the increase of routine preoperative chest CT examination has led to a higher detection rate of TD. Although TD is very rare, it is one of the reasons for difficult intubation and difficult ventilation. Improper treatment can cause severe airway emergencies such as diverticulum tearing, tracheal rupture, and subcutaneous or mediastinal emphysema. Unfortunately, there are few studies on TD, especially in perioperative airway and anesthesia management. This paper reports a case of TD found by preoperative chest CT examination who required tracheal intubation under general anesthesia. For the first time, ultrasound was used to confirm the position of tracheal tube and TD, and good results were achieved. This attempt provides a new idea and method for airway management in patients with TD.

Delayed Anaphylactic Reaction to Midazolam in the Absence of Immediate Respiratory or Skin Manifestations

Anaphylaxis, a type 1 hypersensitivity reaction, is a feared but uncommon complication of medications administered in the perioperative period. The incidence of perioperative hypersensitivity reactions has been reported to range from 1 in 20,000 to 1 in 1,361. Anesthesiologists are well aware of common causes of hypersensitivity such as paralytics and antibiotics; however, less common triggers of anaphylaxis need to be considered as well. Midazolam, a short acting benzodiazepine metabolized by cytochrome P450 enzymes, is considered very safe with a minimal risk profile. Previous reports have described adverse reactions to occur within seconds to minutes following the administration of midazolam. We describe a patient with no known history of asthma or allergies who underwent elective hydrocelectomy with spinal analgesia without incident until 42 minutes later at the conclusion of the procedure, when they experienced circulatory collapse necessitating immediate emergency treatment. This case emphasizes the necessity to improve knowledge and awareness of delayed hypersensitivity reactions following the administration of perioperative medications such as midazolam.

Video Laryngoscope Assistance in Button Battery Retrieval

Foreign body ingestion remains a common cause of pediatric emergency surgery with button battery ingestion of particular concern. Newer, higher power lithium batteries can cause catastrophic damage of the gastrointestinal tract through erosion of mucosa into surrounding structures. Prompt diagnosis and treatment are paramount. We present a case of an 11-month-old with a button battery lodged in the proximal esophagus. The extraction was difficult and only made possible with the assistance of a video laryngoscope. We make the case for more routine usage of video laryngoscopy for removal of foreign bodies in the upper esophagus.
