1 mg/kg. After 4 minutes of applying HFNC, with SpO2 rising from 76% to 98%, anesthetic medications were administered intravenously without a neuromuscular blocking agent to preserve spontaneous breathing. The patient was not ventilated with a facemask but instead left with HFNC in place for continuous supplemental oxygenation. The patient's airway was secured in a single attempt in 80 seconds. HFNC is an ideal option for oxygen supplementation during airway management of pediatric FSV patients, as their balance of pulmonary and systemic flow is perturbed easily by subtle physiologic alteration and therapeutic maneuvers during the induction of general anesthesia and highly susceptible to rapid desaturation and cardiovascular collapse, and should be considered as having a physiologically difficult airway.Clinical manifestations of coronavirus disease 2019 in pregnant women, in contrast to previous outbreaks, seem to be similar to those of nonpregnant women. During severe acute respiratory syndrome (SARS), SARS influenza A, and Middle East respiratory syndrome outbreaks, an increased severity of disease among pregnant women was observed. In some pregnant women, respiratory failure can occur and progress quickly to acute respiratory distress syndrome requiring extracorporeal membrane oxygenation (ECMO) as a rescue therapy. Despite a lack of current guidelines on the use of ECMO in pregnant or postpartum women, this support therapy is an effective salvage therapy for patients with cardiac and/or respiratory failure, and is associated with favorable maternal and fetal outcomes. Herein, the authors report a case of severe COVID-19 disease in a pregnant patient after urgent cesarean delivery, who was treated successfully with ECMO during the postpartum. Extracorporeal membrane oxygenation should be considered early when conventional therapy is ineffective, and it is essential to refer to ECMO expert centers.<br /><br /> To demonstrate that the analysis of the atrioventricular, intraventricular, and interventricular asynchrony by point-of-care ultrasound (POCUS) could be an alternative tool for assessing complex arrhythmias in pediatric patients with congenital heart diseases, mainly when an epicardial register or electrophysiology study is not available.<br /><br /> Descriptive, retrospective case series study.<br /><br /> The pediatric intensive care unit of a university-affiliated tertiary hospital in Spain.<br /><br /> The authors included 12 patients with congenital heart disease younger than 18 years admitted to the authors' pediatric intensive care unit (PICU) from January 2018 to December 2019, with complex arrhythmias after surgery, managed by performing a bedside echocardiography when an electrophysiology test or epicardial auriculogram was unavailable.<br /><br /> None.<br /><br /> The authors included a total of 14 complex arrhythmias in 12 postsurgical patients in whom a comprehensive transthoracic electrocardiogram was not conclusive. The presence of atrioventricular, intraventricular, or interventricular asynchrony was assessed in standard echo views by performing M-mode and Doppler mitral inflow analysis, checking the heart motion. The final POCUS diagnoses were atrial flutter (n = 5), postsurgical atrioventricular block (n = 4), asynchrony induced by pacemaker (n = 2), junctional ectopic tachycardia (n = 1), nodal rhythm plus ventricular extrasystole (n = 1), and supraventricular tachycardia (n = 1). In all patients, regardless of the type of arrhythmia, detecting motion asynchrony was crucial for making the correct diagnosis. Offline cardiologist analysis of the POCUS scans showed full agreement.<br /><br /> POCUS is a useful tool for initial diagnosis and management of complex arrhythmias in the PICU, mainly when epicardial auriculogram or electrophysiology studies are unavailable.<br /><br />POCUS is a useful tool for initial diagnosis and management of complex arrhythmias in the PICU, mainly when epicardial auriculogram or electrophysiology studies are unavailable.Perioperative sodium abnormalities or dysnatremia is not uncommon in patients presenting for cardiac surgery and is associated with increased morbidity and mortality. Both the disease process of heart failure and its treatment may contribute to abnormalities in serum sodium concentration. Serum sodium is the main determinant of serum osmolality, which in turn affects cell volume. Brain cells are particularly vulnerable to changes in serum osmolality because of the nondistensible cranium. The potentially catastrophic neurologic sequelae of rapidly correcting chronic dysnatremia and the time-sensitive nature of cardiac surgery can make the management of these patients challenging. The use of cardiopulmonary bypass to facilitate surgery adds another layer of complexity in the intraoperative management of sodium and water balance. This narrative review examines the definition and classification of dysnatremia. It also covers the etiology and pathophysiology of dysnatremia, implications during cardiac surgery requiring cardiopulmonary bypass, and the perioperative management of dysnatremia.Coronavirus disease 2019, caused by severe acute respiratory syndrome coronavirus 2, is now a global pandemic affecting more than 12 million patients across 188 countries. A significant proportion of these patients require admission to intensive care units for acute hypoxic respiratory failure and are at an increased risk of developing cardiac arrhythmias. The presence of underlying comorbidities, pathophysiologic changes imposed by the disease, and concomitant polypharmacy, increase the likelihood of life-threatening arrhythmias in these patients. Supraventricular, as well as ventricular arrhythmias, are common and are associated with significant morbidity and mortality. It is important to understand the interplay of various causal factors while instituting strategies to mitigate the impact of modifiable risk factors. Furthermore, avoidance and early recognition of drug interactions, along with prompt treatment, might help improve outcomes in this vulnerable patient population.<br /><br /> To compare the clinical performance in terms of procedure time, success rate, and cannulation attempts between ultrasound biplane view (BPX) and short-axis (SAX) view for internal jugular vein cannulation (IJV) in patients undergoing cardiac surgery.<br /><br /> Prospective, observational pilot study.<br /><br /> University level tertiary referral hospital.<br /><br /> The study comprised 100 patients between ages 18 and 75 years undergoing elective cardiac surgery.<br /><br /> One hundred patients were divided into 2 groups of 50 (BPX group and SAX group) by assigning the study participants alternatively to each group. IJV cannulation was performed using a 3-dimensional ultrasound probe in all patients with either BPX view (BPX group, n = 50) or the SAX view (SAX group, n = 50) by an experienced anesthesiologist.<br /><br /> Time required for imaging, time for IJV puncture, time for guidewire confirmation, number of needle punctures and needle redirections, and incidence of posterior wall puncture were noted in both groups.
