Objective: The objective of the present study was to compare ultrasound-guided long-axis (LAX) and short-axis (SAX) femoral artery catheterization in neonates and infants undergoing cardiac surgery.
Design: A single-center, prospective, randomized, single-blinded, controlled study.
Setting: This study was conducted in the operating room and intensive care unit of the division of cardiac surgery, Mansoura University Children's Hospital, Egypt.
Participants: Ninety neonates and infants undergoing elective cardiac surgery were enrolled in this study and randomly allocated to ultrasound-guided LAX and SAX groups.
Interventions: Ultrasound-guided femoral artery catheterization was done using either LAX (in-plane) or SAX (out-of-plane) technique.
Measurements And Main Results: The primary outcome measure was the rate of a successful first puncture. The secondary outcome measures were the rates of mechanical complications, failure rate, time to a successful first, second, and third puncture, total time of catheterization, and imaging time. The first puncture success rate was significantly higher (p = 0.048) in the LAX group (34 of 41, 82.9%) than in the SAX group (25 of 41, 60.9%). The mean time to a successful first puncture was significantly shorter (p < 0.001) in the LAX group (153.1 ± 30.1 seconds) than in the SAX group (227.2 ± 48.8 seconds). The total catheterization time was significantly shorter in the LAX group than in the SAX group. There was no significant difference in the rate of complication.
Conclusion: With a single experienced operator performing the ultrasound-guided femoral artery cannulation, the LAX technique resulted in a higher first puncture success rate and shorter time to cannulation than the SAX technique.

The absence or dysplasia of the iliac artery(IA) is an exceedingly rare condition, with limited cases documented in the literature. In this report, we present a case of hypoplasia of the right external iliac artery (EIA) in a 69-year-old male patient. The patient presented with right lower abdominal pain attributed to an aneurysm of the right internal iliac artery (IIA), yet notably, there was no evidence of lower limb ischemia at the time of consultation.

Complex wound closure scenarios necessitate the development of advanced wound dressings that can effectively address the challenges of filling irregularly shaped wounds and managing fatigue failures encountered in daily patient activities. To tackle these issues, we develop a multifunctional hydrogel from natural polysaccharides and polypeptides with injectability and self-healing properties for promoting full-time and multipurpose wound healing. Synthesized through dynamic Schiff base linkages between oxidized hyaluronic acid (OHA), ε-polylysine (ε-PL), and quaternized chitosan (QCS), the OHA/ε-PL/QCS hydrogel can gel rapidly within 50 s.

Purpose Of Review: This review assesses the outcomes of coronary interventions in patients with liver cirrhosis and coronary artery disease (CAD), focusing on the clinical challenges posed by cirrhosis-related hemodynamic and coagulopathic changes. It highlights essential considerations for managing these patients, who have an increased risk of adverse events during coronary procedures.
Recent Findings: Recent studies have shown that patients with liver cirrhosis undergoing PCI experience significantly higher mortality rates compared to non-cirrhotic patients, particularly in the context of STEMI and NSTEMI.

Emergency bleeding presents significant challenges such as high blood flow and rapid hemorrhaging. However, many existing hemostatic bandages face limitations, including the uncontrolled release of hemostatic agents, insufficient mechanical strength, poor adhesion, and complex manufacturing processes. To address these limitations, we developed a multifunctional hydrogel bandage for emergency hemostasis using a one-pot synthesis method.

Measurement of blood flow during exercise is crucial for understanding physiological responses and performance outcomes. However, traditional methods are often invasive, costly, or require substantial training, limiting widespread research in this area. This study introduces the innovative use of limb-affixed ultrasound probe holders for vascular imaging during exercise to overcome these challenges.
