Summary
Indian anesthesiologists show suboptimal Chemical, Biological, Radiological, and Nuclear (CBRN) disaster preparedness. While training boosts knowledge, systemic reforms are needed for better institutional and behavioral readiness in CBRN events.
Area of Science:
- Medical Sciences
- Public Health
- Emergency Medicine
Background:
- Chemical, Biological, Radiological, and Nuclear (CBRN) disasters pose significant threats requiring specialized preparedness.
- Anesthesia professionals play a critical role in managing mass casualty incidents and public health emergencies.
Purpose of the Study:
- To evaluate knowledge, attitudes, practices (KAP), and institutional support for CBRN disaster preparedness among Indian anesthesia professionals.
- To identify factors influencing readiness and barriers to effective preparedness in this cohort.
Main Methods:
- A cross-sectional, web-based survey was administered to 294 anesthesia professionals across India.
- The study assessed four domains: knowledge, attitude, practice, and institutional support using a validated questionnaire.
- Statistical analyses included descriptive statistics, multivariable linear regression, and thematic analysis of open-ended responses.
Main Results:
- Only 10.9% of respondents had received prior CBRN training, and 8.2% had participated in drills.
- Participants with CBRN training exhibited significantly higher knowledge scores compared to untrained individuals.
- Key barriers identified were lack of formal training, inadequate personal protective equipment (PPE), and absence of Standard Operating Procedures (SOPs).
Conclusions:
- CBRN disaster preparedness among Indian anesthesiologists is currently inadequate.
- Formal training significantly enhances knowledge, but comprehensive readiness necessitates systemic institutional changes.
- Recommendations include structured training programs, stakeholder engagement, and simulation-based curricula for improved preparedness.

01:23Assessment of Respiration
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...

01:23Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...

01:26Pharmaceutical Poisoning: Potential Scenarios
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...
01:22Healthcare Associated Infections II: Preventive Measures
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

01:22Cardiopulmonary Resuscitation II: ACLS Airway Management
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
01:26Standard Precaution
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...
