From the Guidelines

Post-catheterization psychosis should be managed with a combination of antipsychotic medications and supportive care, prioritizing the treatment of underlying causes and control of symptoms to minimize morbidity, mortality, and improve quality of life. When managing post-catheterization psychosis, it is essential to consider the patient's overall clinical presentation, including the presence of delirium or other altered mental status changes 1. According to the most recent guidelines, delirium is a defined and diagnosable medical condition that requires early detection and accurate diagnosis to prevent increased mortality 1. The treatment of post-catheterization psychosis involves a combination of antipsychotic medications, such as haloperidol or quetiapine, and supportive care, including ensuring the patient is in a safe environment and addressing underlying causes such as medication effects, metabolic disturbances, or cerebral microembolism from the procedure 1. Some key points to consider in the management of post-catheterization psychosis include:

  • Investigating underlying causes, including medication effects, metabolic disturbances, hypoxia, or cerebral microembolism from the procedure 1
  • Using low-dose antipsychotics, such as haloperidol 0.5-1mg orally or intramuscularly every 4-6 hours as needed, with careful monitoring for QT prolongation 1
  • Preferring atypical antipsychotics like quetiapine 25-50mg at bedtime in elderly patients due to fewer extrapyramidal side effects 1
  • Ensuring the patient is in a safe, well-lit environment with familiar objects and family members present when possible to reduce disorientation 1
  • Addressing sleep disturbances, hydration, and correction of electrolyte abnormalities as important supportive measures 1 It is crucial to prioritize the treatment of underlying causes and control of symptoms to minimize morbidity, mortality, and improve quality of life in patients with post-catheterization psychosis, as highlighted in the most recent study 1.

From the Research

Post Cath Psychosis

  • There are no research papers provided that directly discuss post cath psychosis, however, the studies provided do discuss the treatment of psychotic conditions with various antipsychotic medications 2, 3, 4, 5, 6.

Treatment of Psychotic Conditions

  • The studies provided compare the effectiveness of different antipsychotic medications, including haloperidol, risperidone, olanzapine, quetiapine, ziprasidone, and aripiprazole, in the treatment of first-episode psychosis 3, 4, 5, 6.
  • The results of these studies suggest that second-generation antipsychotics, such as olanzapine, risperidone, and quetiapine, may be more effective and better tolerated than first-generation antipsychotics, such as haloperidol, in the treatment of psychotic conditions 2, 3, 4, 5, 6.

Comparison of Antipsychotic Medications

  • A study published in 2008 found that olanzapine, risperidone, and quetiapine were as effective as haloperidol in the treatment of psychotic agitation, but with fewer extrapyramidal symptoms 2.
  • A study published in 2006 found that olanzapine, risperidone, and haloperidol were equally effective in reducing the severity of psychopathology in first-episode nonaffective psychosis, but with different side effect profiles 3.
  • A study published in 2011 found that risperidone and olanzapine were more effective than haloperidol in the treatment of first-episode nonaffective psychosis, with fewer treatment discontinuations 4.
  • A study published in 2012 found that olanzapine was more effective than haloperidol and ziprasidone in the treatment of first-episode psychosis, with longer treatment continuation and fewer discontinuations 5.
  • A study published in 2020 found that olanzapine, risperidone, and aripiprazole were more effective than haloperidol, quetiapine, and ziprasidone in the treatment of first-episode psychosis, with fewer treatment discontinuations and better tolerability 6.
