A complex case of posterior reversible encephalopathy syndrome after combined spinal epidural of preeclampsia parturient: A case report.

Posterior reversible encephalopathy syndrome (PRES) is a disorder characterized by vasogenic edema affecting the posterior brain region. We report a case of PRES in a 36-year-old woman with preeclampsia who underwent an emergency cesarean section with spinal anesthesia. After surgery, she developed right leg weakness, headache, and seizures. Imaging showed white matter edema consistent with PRES. The exact cause of PRES is unclear, but elevated blood pressure and endothelial dysfunction are implicated. Tight blood pressure control in PRES is crucial for management, and prompt recognition and treatment are essential for favorable outcomes.

Severe pulmonary edema occurred during endobronchial ultrasound under monitored anesthesia care - A case report.

BACKGROUND: Endobronchial ultrasound (EBUS) is widely used to diagnose lung cancer. Monitored anesthesia care (MAC) can enhance patient comfort and procedural conditions during EBUS. EBUS under MAC is usually safe but can lead to various complications. CASE: A 34-year-old male who had increased sputum for two months showed an enlarged paratracheal lymph node and planned for lymph node biopsy by EBUS. During EBUS under MAC, an unexpected oxygen saturation decline required intervention. After intubation, copious frothy fluid was suctioned from the bronchi, and oxygenation was recovered. A narrowed trachea and the EBUS bronchoscope might have resulted in upper airway obstruction, and suction performed under these conditions might have caused pulmonary edema. The patient received non-invasive ventilation and high-flow nasal cannula and recovered without complications. CONCLUSIONS: When there is an expected risk of upper airway obstruction during EBUS, careful preoperative evaluation and preparation are essential to prevent negative pressure pulmonary edema.

Anesthetic management of an elderly COVID-19 patient with pulmonary thromboembolism for hip surgery - A case report.

BACKGROUND: COVID-19 and delayed hip surgery are well-known risk factors for thromboembolism in elderly patients. CASE: We report the case of an 88-year-old female patient with COVID-19 and pulmonary thromboembolism (PTE) who underwent delayed hip surgery 21 days after the injury. Heparinization and inferior vena cava filters were used to treat and prevent PTE. Transesophageal echocardiography and extracorporeal membrane oxygenation (ECMO) sheaths were inserted as a precaution in case of emergencies during surgery; the procedure was performed without any specific event. CONCLUSIONS: COVID-19-infected patients suffering from a hip fracture have a high risk of thromboembolism, and therefore, require utmost attention for appropriate evaluation and prevention.
