ReviewVolatile and Intravenous Anesthetics for Brain Protection in Cardiac Surgery: Does the Choice of Anesthesia Matter?
Postoperative neurologic complications have a significant effect on morbidity, mortality, and long-term disability in patients undergoing cardiac surgery. The etiology of brain injury in patients undergoing cardiac surgery is multifactorial and remains unclear. There are several perioperative causative factors for neurologic complications, including microembolization, hypoperfusion, and systemic inflammatory response syndrome. ⋯ Moreover, despite the strong evidence that volatile anesthesia exerts cardioprotective effects in patients undergoing cardiac surgery, the neuroprotective effects of volatile agents remain unclear. Several studies have reported an association of using volatile anesthetics with improvement of biochemical markers of brain injury and postoperative neurocognitive function. However, there is a need for additional studies to define the optimal anesthetic drug for protecting the brain in patients undergoing cardiac surgery.

ReviewFluoroscopic Imaging for the Interventional Echocardiographer.
Procedural guidance during structural heart disease (SHD) interventions is achieved with both two-dimensional and three-dimensional transesophageal echocardiography as well as real-time fluoroscopic imaging. Although both image the cardiac anatomy, they are based on different principles of image acquisition. In the era of multimodality imaging with coregistration of anatomic landmarks and simultaneous real-time display, it is essential to have cross-disciplinary imaging knowledge. ⋯ In this study, the authors used a novel fluoroscopic phantom cardiac model with enhanced structural markers to display the basic fluoroscopic images used during SHD interventions. The projected images enhance the understanding of the orientation and relationship among intracardiac structures as seen on fluoroscopy. In this study, the authors present the basic fluoroscopic views for SHD interventions and the anatomic relationship for intracardiac structures using a custom-made phantom fluoroscopic heart model.

Physical Therapy and Sedation While on Extracorporeal Membrane Oxygenation for COVID-19-Associated Acute Respiratory Distress Syndrome.
This study aimed to determine whether patients on extracorporeal membrane oxygenation (ECMO) with coronavirus disease 2019 (COVID-19) achieved lower rates of physical therapy participation and required more sedation than those on ECMO without COVID-19. ⋯ The results of this matched cohort study supported that sedation requirements were not dramatically greater and did not significantly limit early physical therapy for patients who had COVID-19-associated ARDS and were on venovenous extracorporeal membrane oxygenation (VV-ECMO) versus those without COVID-19-associated ARDS who were on VV-ECMO.

Case ReportsUltrasound-Guided Thoracic Paravertebral Block for Pulmonary Radiofrequency Ablation.
Surgical resection is the treatment of choice both for early-stage lung cancer and pulmonary metastatic disease. For patients with lung tumors who are not eligible for surgery, the minimally invasive modality of radiofrequency ablation (RFA) may be curative and, thus, should be considered. However, opinions regarding the optimal anesthetic technique for pulmonary RFA differ. ⋯ No patient required conversion from sedation to general anesthesia. There were no episodes of hemodynamic instability or desaturation (SaO2 ≤95%), and excessive sedation prevented patient collaboration in only one patient. In conclusion, ultrasound-guided single-injection TPVB is a safe and effective anesthetic technique for high-risk patients undergoing RFA for a primary lung tumor or lung metastases.
