Pulmonary Embolism III: Nursing Management01:27

Pulmonary Embolism III: Nursing Management

453
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

475
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Pulmonary Embolism I: Introduction

755
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Air-entraining Agents01:27

Air-entraining Agents

276
Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Effects of Air-entrainment in Concrete01:28

Effects of Air-entrainment in Concrete

396
Air entrainment in concrete significantly enhances the material's durability, especially in environments subjected to freeze-thaw cycles. Introducing small air bubbles into the concrete mix acts as internal voids that accommodate the expansion of water when it freezes, thereby alleviating internal stress and preventing structural cracks. This function is crucial in climates with significant freezing and thawing, as it protects the concrete from repeated stresses that could lead to premature...

Measurement of Air Content in Concrete01:23

Measurement of Air Content in Concrete

668
Air content measurement in concrete is critical for ensuring structural integrity and durability of concrete structures, especially in environments prone to severe weather conditions. Accurate air content analysis optimizes concrete's resistance to freeze-thaw cycles and enhances its workability and strength. Several methods are standardized under ASTM guidelines to measure the air content in fresh concrete, each suitable for different concrete types and conditions.
The pressure method,...

    Summary
    This summary is machine-generated.

    Air emboli were detected in 30% of patients during hip replacement surgery using heart auscultation. This finding, confirmed by ultrasonic devices, suggests routine cardiac monitoring during surgery is beneficial.

    • Surgical Safety
    • Orthopedic Surgery

    Background:

    • Hip replacement surgery involves risks, including potential complications from acrylic bone cement and prosthesis insertion.
    • Air embolism is a recognized but often undetected complication during surgical procedures.

    Purpose of the Study:

    • To investigate the incidence of air emboli during hip replacement surgery.
    • To evaluate the effectiveness of cardiac auscultation in detecting air emboli.

    Main Methods:

    • Cardiac auscultation was performed on 49 patients during hip replacement surgery.
    • Ultrasonic transducers were used to confirm the presence of air emboli in subsequent patients.
    • Data on the detection of air emboli sounds were collected and analyzed.

    Main Results:

    • Characteristic sounds of air emboli were heard in 15 out of 49 patients (30%).
    • Ultrasonic monitoring confirmed the auscultation findings in later cases.
    • The study identified a significant incidence of air embolism during this procedure.

    Conclusions:

    • Routine cardiac auscultation is a feasible method for detecting air emboli during hip replacement.
    • The findings support the recommendation for continuous cardiac monitoring during acrylic bone cement and prosthesis insertion.
    • Early detection of air emboli can potentially improve patient outcomes and surgical safety.
