Pulmonary Embolism I: Introduction

Pulmonary Embolism I: Introduction

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...

Avoidance Learning and Learned Helplessness

Avoidance Learning and Learned Helplessness

Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Pulmonary Embolism III: Nursing Management

Pulmonary Embolism III: Nursing Management

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...

Associative Learning

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Purposive Learning

Purposive Learning

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

Observational Learning

Observational Learning

Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Summary

This summary is machine-generated.

Transarterial embolization (TAE) for postpartum hemorrhage (PPH) can fail. Risk factors like placental retention and high INR predict failure, while the post-TAE shock index offers timely indication.

Background:

Transarterial embolization (TAE) is a key treatment for postpartum hemorrhage (PPH).
Clinical failure of TAE occurs, necessitating further interventions.
Predicting TAE failure is crucial for timely management.

Purpose of the Study:

To identify predictors of clinical failure in TAE for PPH.
To determine if supplementary interventions can be promptly initiated based on these predictors.
To evaluate the utility of the post-TAE shock index in predicting failure.

Main Methods:

Retrospective analysis of 118 TAE procedures in 113 PPH patients (Jan 2012 - May 2015).
Comparison of clinical success vs. failure groups based on gestational conditions, angiographic factors, vital signs, and lab data.
Multivariate logistic regression and shock index analysis.

Main Results:

84.8% of TAE procedures were clinically successful.
Independent risk factors for TAE failure included augmented embolic agents, placental retention, and INR > 1.3.
A post-TAE shock index cutoff of 0.8 was significantly associated with TAE failure.

Conclusions:

Pre-procedural and intra-procedural factors predict TAE failure.
The post-TAE shock index, while not an independent factor, timely indicates clinical failure.
Early identification of risk factors and post-procedural indicators can guide management of PPH after TAE.
