Dysrhythmias VII: Nursing Management of Dysrhythmias

290
Nursing management of dysrhythmias involves the following:AssessmentSubjective Assessment:The initial step involves gathering patient-reported symptoms such as dizziness, palpitations, and chest discomfort. It is crucial to collect a detailed history, including previous heart conditions, current medication use, and lifestyle factors like caffeine and alcohol consumption.Objective Assessment:This involves observing clinical signs such as jugular venous distention, cool and pale skin, and...

Psychosis: Goals of Pharmacotherapy

415
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.

Acute Coronary Syndrome IV: Interprofessional Care

188
IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Mania and Antimanic Drugs: Overview

499
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...

Pneumonia IV: Management

703
The treatment of pneumonia varies based on its severity and the causative pathogen. Here is a structured approach to managing pneumonia, integrating pharmaceutical and supportive care strategies.
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

Esophageal Varices-II: Clinical Features and Management

329
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Summary

Preventing and treating delirium in critically ill patients remains challenging. While multicomponent non-pharmacologic strategies show promise, antipsychotics are ineffective for intensive care unit (ICU) delirium.

Area of Science:

  • Critical Care Medicine
  • Neuroscience
  • Geriatrics

Background:

  • Delirium is a common and serious complication in critically ill patients.
  • It is associated with poor short-term and long-term outcomes.

Purpose of the Study:

  • To review recent findings on delirium prevention and treatment in critically ill patients.
  • To provide expert recommendations and identify knowledge gaps.

Main Methods:

  • Review of recent studies and expert guidelines on delirium management.
  • Analysis of evidence for non-pharmacologic and pharmacologic interventions.

Main Results:

  • Multicomponent non-pharmacologic interventions, like the ABCDEF bundle, show potential benefits in the ICU.
  • Antipsychotics have proven ineffective in preventing or shortening delirium duration in ICU patients.
  • Dexmedetomidine and ramelteon show promise but require more research.

Conclusions:

  • Effective delirium management strategies are still needed.
  • Non-pharmacologic interventions are supported by current evidence.
  • Future research should explore novel non-pharmacologic and non-antipsychotic pharmacologic treatments.
