    PURPOSE OF REVIEW This review describes maternal and fetal anesthetic management for noncardiac fetal surgical procedures, including the management of lower urinary tract obstruction, congenital diaphragmatic hernia (CDH), myelomeningocele, sacrococcygeal teratoma, prenatally anticipated difficult airway and congenital lung lesions. RECENT FINDINGS Fetal interventions range from minimally invasive fetoscopic procedures to mid-gestation open surgery, to ex-utero intrapartum treatment procedure. Anesthetic management depends on the fetal intervention and patient characteristics. Anesthesia for most minimally invasive procedures can consist of intravenous sedation and local anesthetic infiltration in clinically appropriate maternal patients. Open fetal and ex-utero intrapartum treatment procedures require maternal general anesthesia with volatile anesthetic and other medications to maintain uterine relaxation. Tracheal balloons are a promising therapy for CDH and can be inserted via minimally invasive techniques. Management of the prenatally anticipated difficult airway during delivery and removal of tracheal balloons from patients with CDH during delivery can be clinically dynamic and require flexibility, seamless communication and a high-functioning, multidisciplinary care team. SUMMARY Maternal and fetal anesthetic management is tailored to the fetal intervention and the underlying health of the fetus and mother.PURPOSE OF REVIEW There have been both technological and philosophical advances over the last decade regarding pacemakers and implanted cardioverter defibrillators (ICDs). Collectively, these devices are currently referred to as cardiac implantable electronic devices (CIEDs). Technological advances include the introduction of leadless pacemakers, subcutaneous defibrillators and cardiac event recorders, enhancements regarding compatibility of CIEDs for MRI scanning, the ability to interrogate devices remotely, and improved programming modes that preserve battery life. Philosophical advances have been mainly in the area of perioperative management of CIED patients. RECENT FINDINGS Current practice recommendations now acknowledge that not every patient requires a formal interrogation of their CIED before and after surgery (as was previously recommended). The response to magnet application is standardized across manufacturer’s platforms, and it is known that sources of electromagnetic interference remote from the CIED and its leads do not usually cause any interference with device function. SUMMARY Educated anesthesia teams can independently manage the vast majority of CIED patients perioperatively with magnet application alone. Furthermore, this portends enhanced patient safety and improved workflows in the perioperative period.PURPOSE OF REVIEW The goal of risk prediction is to identify high-risk patients who will benefit from further preoperative evaluation. Clinical scores and biomarkers are very well established tools for risk prediction but their accuracy remains a controversial issue. RECENT FINDINGS Current guidelines recommend one of the risk tools for preoperative cardiac risk assessment American College of Surgeons National Surgical Quality Improvement Program (NSQIP) calculator or Revised Cardiac Risk Index. Although not as easy to use as risk scores, risk models are more accurate and can predict individual patient risk more precisely. A step forward in risk estimation was performed by introducing new risk models developed from the American College of Surgeons NSQIP database – NSQIP surgical risk calculator and Myocardial Infarction or Cardiac Arrest index. Although biomarkers, especially in cardiac risk assessment, are already present in current European and American guidelines, this use is still controversial. Novel biomarkers microRNAs, heart-type fatty acid-binding protein and mid-regional proadrenomedullin, can be used as new potential biomarkers in clinical practice. Also some of the experimental biomarkers have not yet been introduced into clinical practice, preliminary results are encouraging. SUMMARY Different risk indices and biomarkers might lead to varying risk estimates. However, the importance of clinical judgment in risk assessment should not be underestimated.PURPOSE OF REVIEW Although the indications for β-blockers in the management of patients with congestive heart failure and myocardial infarction are well established, the use of β-blockers in the perioperative setting remains controversial. RECENT FINDINGS Since 2008 PeriOperative ISchemic Evaluation Trial, there have been numerous studies suggesting that perioperative β-blockers are associated with adverse events such as hypotension, bradycardia, increased mortality, and stroke. SUMMARY In this article, we review the most recent evidence to suggest an approach to perioperative β-blocker use tailored to patient and surgical risk factors. We also review recent studies on off-label uses for perioperative β-blockers.PURPOSE OF REVIEW To review the perioperative applications of point-of-care ultrasound (POCUS). RECENT FINDINGS The role of point-of-care ultrasonography for perioperative care is expanding with respect to perioperative application. The imaging approach can complement the physical exam and provide additional information for decision-making in pediatric perioperative medicine. OPB-171775 manufacturer This review will focus on applications in the following organ systems airway, cardiac, pulmonary and gastric. Specifically, POCUS of the airway has been used to optimize endotracheal tube depth, aid in tube size selection and predict difficulty with laryngoscopy and intubation. Lung POCUS has been used to assess for causes hypoxemia as well as to optimize ventilatory mechanics. Cardiac POCUS has been used for assessment of hemodynamics, valvular and ventricular function. Gastric ultrasound has emerged as an evaluative mechanism of gastric content in the setting of fasting as well as to confirm placement of gastric tubes. The applications of POCUS in the perioperative setting continue to evolve as a reliable diagnostic tool that can assist in timely diagnosis, improve procedural safety and has the potential to improve patient outcomes. SUMMARY The utility of perioperative POCUS has been well demonstrated, specifically for examination of the airway, stomach and cardiopulmonary system. It is advisable for the novice sonographer to perform POCUS within the guidelines set by the American Society of Echocardiography regarding basic POCUS. As with all diagnostic modalities, understanding the limitations of ultrasound and POCUS as well as continuous self-assessment is crucial.
