Case Reports in Critical Care
|October 5, 2020
Summary
The Lazarus phenomenon is autoresuscitation after cardiopulmonary resuscitation (CPR) is stopped. Physicians should monitor patients longer before declaring death to avoid this rare event.
Area of Science:
- Medical Science
- Clinical Medicine
- Emergency Medicine
Background:
- The Lazarus phenomenon, or autoe resuscitation, describes spontaneous return of circulation after cessation of cardiopulmonary resuscitation (CPR).
- This rare event highlights the complexities of determining death in clinical settings.
- Understanding the pathophysiology of the Lazarus phenomenon is crucial for medical professionals.
Observation:
- Patients declared dead after failed CPR have, in rare instances, shown spontaneous autoresuscitation.
- This phenomenon underscores the potential for misinterpreting the finality of death following resuscitation efforts.
- Clinical observation periods post-CPR may need re-evaluation.
Findings:
- The Lazarus phenomenon is an infrequent occurrence, with its underlying pathophysiology not fully elucidated.
- Physicians must maintain awareness of this possibility to prevent premature pronouncements of death.
- Current protocols for declaring death may require refinement.
Implications:
- Healthcare providers should consider extending monitoring periods after CPR cessation.
- Utilizing tools like electrocardiograms and blood pressure monitoring can aid in confirming death.
- Enhanced vigilance can prevent potential ethical and clinical complications associated with the Lazarus phenomenon.

01:20Lazarus's Cognitive Appraisal Theory
1.2K
Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.

01:23Acute Respiratory Failure-IV
399
Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...

01:18Metabolic States of the Body: The Postabsorptive State
1.1K
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

01:21Kubler Ross's Stages of Dying
773
Elisabeth Kübler-Ross significantly advanced psychology's understanding of the process of dying with her influential book, On Death and Dying (1969). She focused on studying terminally ill individuals and outlined five stages commonly experienced when coping with death: denial, anger, bargaining, depression, and acceptance.
In denial, individuals reject the reality of their condition, often thinking, "This isn't true; I feel fine," as a way to protect themselves from...

01:24Muscle Recovery and Fatigue
3.7K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

01:07Narcolepsy
344
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
