ABSTRACT Percutaneous cannulation of the femoral vein, in the pediatric age group, can be technically challenging, especially when performed by residents in training. We examined whether the use of real-time ultrasound guidance is superior to a landmark technique for femoral vein catheterization in children undergoing heart surgery.
Patients were prospectively randomized into 2 groups. In group LM, the femoral vein was cannulated using the traditional method of palpation of arterial pulse. In group US, cannulation was guided by real-time scanning with an ultrasound probe. The time to complete cannulation (primary outcome), success rate, number of needle passes, number of successful cannulations on first needle pass, and incidence of complications were compared between the 2 groups.
Forty-eight pediatric patients were studied. The time to complete cannulation was significantly shorter (155 [46-690] vs 370 [45-1620] seconds; P = 0.02) in group US versus group LM. The success rate was similar in both groups (95.8%). The number of needle passes was smaller (1 [1-8] vs 3 [1-21]; P = 0.001) and the number of successful cannulations on first needle pass higher (18 vs 6; P = 0.001) in group US compared with group LM. The incidence of femoral artery puncture was comparable between the 2 groups.
Ultrasound-guided cannulation of the femoral vein, in pediatric patients, when performed by senior anesthesia residents, is superior to the landmark technique in terms of speed and number of needle passes, with remarkable improvement in first attempt success.

    ABSTRACT: Point-of-care ultrasound (POCUS) has become an integral part of emergency medicine practice. Research evaluating POCUS in the care of pediatric patients has improved the understanding of its potential role in clinical care. Recent work has investigated the ability of pediatric emergency medicine (PEM) physicians to perform a wide array of diagnostic and procedural applications in POCUS ultrasound. Studies have demonstrated that PEM providers are able to identify an array of diseases, including intussusception, pyloric stenosis and appendicitis. Novel applications of ultrasound, such as a cardiac evaluation in the acutely ill patient or identification of skull fractures in the assessment of a patient with head injury, have shown excellent promise in recent studies. These novel applications have the potential to reshape pediatric diagnostic algorithms. Key applications in PEM have been investigated in the recent publications. Further exploration of the ability to integrate ultrasound into routine practice will require larger-scale studies and continued growth of education in the field. The use of ultrasound in clinical practice has the potential to improve safety and efficiency of care in the pediatric emergency department.

    ABSTRACT: Ultrasound (US) is the standard of care for vascular access in many clinical scenarios. Limited data exist regarding the benefits of US- versus landmark (LM)-guided femoral vascular access in the pediatric catheterization laboratory. This study aimed to compare US- and LM-guided vascular access in the pediatric catheterization laboratory. A single operator randomized 95 patients (201 vessels) to undergo either LM- or US-guided vascular access. The primary end point was the access success rate. Number of attempts, inadvertent access, time to sheath placement, and complications also were compared between the two groups. No difference was seen in the overall access success rate: 98 % with US versus 93 % with LM (p = 0.17). The success rate for the targeted vessel was higher with US (89 %) than with LM (67 %) (p = 0.012). US facilitated fewer attempts (1.1 ± 0.4 vs 1.4 ± 0.9; p = 0.048) and improved the first-attempt success rate (87 vs 77 %; p = 0.049). The time to access did not differ significantly between the two groups (US 2:55 ± 4:03 vs LM 3:37 ± 2:54; p = 0.28). No differences in complication rates were noted. The benefits of US were accentuated in the subgroup weighing less than 10 kg. In this study, US access in the pediatric catheterization laboratory did not improve overall success. However, US improved accuracy and reduced the number attempts necessary for access without prolonging the access time of the procedure. Small children realized the greatest benefit of US-guided access.

    ABSTRACT: There is increasing interest in the use of ultrasound to assess and guide the management of critically ill patients. The ability to carry out quick examinations by the bedside to answer specific clinical queries as well as repeatability are clear advantages in an acute care setting. In addition, delays associated with transfer of patients out of the Intensive Care Unit (ICU) and exposure to ionizing radiation may also be avoided. Ultrasonographic imaging looks set to evolve and complement clinical examination of acutely ill patients, offering quick answers by the bedside. In this two-part narrative review, we describe the applications of ultrasonography with a special focus on the management of the critically ill. Part I explores the utility of echocardiography in the ICU, with emphasis on its usefulness in the management of hemodynamically unstable patients. We also discuss lung ultrasonography - a vastly underutilized technology for several years, until intensivists began to realize its usefulness, and obvious advantages over chest radiography. Ultrasonography is rapidly emerging as an important tool in the hands of intensive care physicians.
