Anaesthesia and Intensive Care
|October 26, 2006
Summary
Awareness during anesthesia is rare, especially in critical care transport. This case highlights risks like excessive neuromuscular blockers during medical retrievals, emphasizing prevention challenges.
Area of Science:
- Anesthesiology
- Critical Care Medicine
- Emergency Medicine
Background:
- Awareness during general anesthesia involves recalling events, with incidence around 0.2% when neuromuscular blockers are used.
- Most data on anesthesia awareness comes from in-hospital settings.
- Neuromuscular blockers are frequently used in critical care transport to facilitate procedures and patient management.
Observation:
- A case of intra-retrieval awareness occurred in a critically ill patient during out-of-hospital medical transport.
- This event happened despite the use of neuromuscular blockers, a common practice in retrieval medicine.
- The patient experienced recall of events during the transport, indicating a failure in anesthetic depth or monitoring.
Findings:
- Excessive administration of neuromuscular blockers is a significant risk factor for awareness during medical retrievals.
- The unique environment of out-of-hospital transport presents distinct challenges for preventing awareness.
- Inadequate anesthetic depth or monitoring may contribute to awareness in critically ill patients undergoing retrieval.
Implications:
- There is a need to re-evaluate anesthetic practices and monitoring standards for critical care retrieval.
- Strategies to prevent awareness during medical transport, particularly concerning neuromuscular blocker use, require further investigation.
- Improving patient safety during medical retrievals necessitates addressing the specific risks associated with out-of-hospital anesthesia.

01:12Retrieval
Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

01:15Subconsciousness and No Awareness
The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.

01:08The Availability Heuristic
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):
01:06Altered States of Awareness
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

01:10Tip-of-the-Tongue Phenomenon
The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...
01:26Metacognition
Metacognition is a conscious process where individuals are aware of their cognitive and executive processes, such as planning before solving a problem or self-monitoring during reading. For instance, a writer may need help with composing a piece. The situation involves a writer who is working on a piece of writing, but while doing so, they realize that something is missing. They notice that their characters lack depth or details. This realization occurs because the writer is reflecting on their...
