Insights

The Electa autotransfusion device effectively washes red blood cells (RBCs), yielding a high hematocrit and recovery rate. This cell saver demonstrates comparable quality to existing devices for intraoperative use.

Area of Science:

  • Biomedical Engineering
  • Cardiovascular Surgery
  • Transfusion Medicine

Background:

  • Autotransfusion devices are crucial for managing blood loss during surgery.
  • Evaluating new devices like the Electa ensures optimal patient outcomes and resource utilization.

Purpose of the Study:

  • To assess the quality of washed red blood cells (RBCs) produced by the Cobe Cardiovascular Electa autotransfusion device.
  • To compare the Electa's performance against established autotransfusion systems.

Main Methods:

  • Intraoperative blood collection from 16 cardiac surgery patients using routine cell salvage.
  • Washing of collected blood with the Electa device following the manufacturer's protocol.
  • Analysis of reservoir and washed RBCs for hematocrit (Hct), RBC recovery, platelets (PLTs), leukocytes (WBCs), potassium (K+), and plasma-free hemoglobin (PFH).

Main Results:

  • The Electa produced washed RBCs with an average Hct of 58+/-5% and an RBC recovery rate of 87+/-10%.
  • Significant removal of waste products was observed: 54+/-18% WBCs, 87+/-6% PLTs, 91+/-4% K+, and 77+/-17% PFH.
  • The device demonstrated efficient removal of contaminants while preserving RBC viability.

Conclusions:

  • The Electa autotransfusion device yields a high-quality washed RBC product.
  • Its performance is comparable to other commercially available autotransfusion devices.
  • The Electa is a viable option for cell salvage in cardiac surgery.

Psychosis and Antipsychotic Drugs: Overview01:28

Psychosis and Antipsychotic Drugs: Overview

The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic symptoms in all...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...

Psychosis: Goals of Pharmacotherapy

Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...

Theoretical Approaches to Psychological Disorder

The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...
Schizophrenia01:17

Schizophrenia

Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those diagnosed.
Psychological and Sociocultural Causes of Schizophrenia01:29

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
