Radiofrequency (RF) scanning is an increasingly popular method of detecting retained surgical items. RF systems are generally regarded as safe but have the potential to cause electrical interference with pacemakers. This may lead to serious adverse events, including asystole. We present a case of an RF system used with a temporary pacemaker resulting in asystole. With the use of RF devices becoming widespread, it is important for all operating room personnel to recognize the potential for pacemaker interference from RF scanning devices and the requirements for asynchronous pacing when these devices are in use.
The number of patients reaching adulthood after undergoing Fontan palliation for the repair of a congenital heart defect continues to increase. In this case report, we present the anesthetic management of a patient with a history of tricuspid atresia treated with palliative Fontan repair who had developed clinical evidence of Fontan failure. He presented with septic shock secondary to streptococcal toxic shock syndrome complicated by a loculated pleural effusion. He underwent open thoracic decortication under 1-lung ventilation. Discussion focuses on the management of volume status and pulmonary vascular resistance as well as surgical implications of Fontan physiology in thoracic surgery.
Anemia is common in pregnant women and is associated with increased morbidity for the mother and the fetus, including increased risk of allogeneic blood transfusion. Iron deficiency is the most common etiology for anemia during pregnancy. Oral iron therapy remains the standard treatment but is often poorly tolerated due to its gastrointestinal side effects. Intravenous iron has been shown to be a safe and effective way to treat iron deficiency anemia but may be challenging to do in the outpatient setting given the need for an indwelling venous catheter and a small risk of infusion reactions. To improve outcomes associated with anemia, we launched a program to refer and treat obstetric patients with iron deficiency anemia for outpatient intravenous iron therapy through our preoperative anemia clinic. Here, we describe the process and successes of our program, including the clinical outcomes (change in hemoglobin and transfusion rates) from the first 2 years of the program.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
