Insights
This study analyzed avalanche victims in cardiac arrest (CA), finding that while medical management generally followed guidelines, no patients survived. This highlights potential areas for improving avalanche rescue protocols and patient care.
Area of Science:
- Emergency Medicine
- Wilderness Medicine
- Traumatology
Background:
- Avalanche incidents pose significant risks, often leading to cardiac arrest (CA).
- Effective medical management is crucial for improving outcomes in avalanche victims.
- International guidelines exist for managing avalanche victims in CA.
Purpose of the Study:
- To describe and analyze the medical management of avalanche victims in CA.
- To assess clinical course and adherence to international recommendations.
- To identify areas for improvement in avalanche rescue protocols.
Main Methods:
- Retrospective study of avalanche victims in CA from 2004-2016.
- Inclusion of data from a single physician-staffed alpine helicopter emergency medical service.
- Abstraction of data on cardiopulmonary resuscitation (CPR), transport, and extracorporeal life support rewarming (ECLSR).
Main Results:
- 66 victims were studied; 47% declared dead on scene.
- 20% had prehospital return of spontaneous circulation (ROSC).
- 93% of critical decisions aligned with guidelines, yet no survivors were recorded.
Conclusions:
- Medical management of avalanche victims in CA largely adhered to guidelines.
- No survivors were observed in this cohort, indicating a need for further research.
- Potential undertreatment in some cases suggests room for protocol optimization.
Aims:
Our goals were to describe and analyse the medical management and clinical course of avalanche victims in cardiac arrest (CA), focusing on adherence to international recommendations on avalanche victims in CA regarding critical decisions.
Methods:
We retrospectively included all avalanche victims with CA from 1st January 2004 to 1st June 2016 in a single physician-staffed alpine helicopter emergency medical service. Data regarding cardiopulmonary resuscitation (CPR), transportation to hospital whilst undergoing CPR, and extracorporeal life support rewarming (ECLSR) for patients still in CA at hospital admission were abstracted from the prehospital and medical health records.
Results:
Sixty-six victims were included in this study; 31 (47%) were declared dead on scene. Of the remaining 35 victims, 7 (20%) had prehospital return of spontaneous circulation (ROSC), 28 (80%) were transported whilst undergoing CPR, 3 had hospital ROSC and 7 (28%) of the 25 patients with persistent CA at hospital underwent ECLSR. The medical management comprised 126 documented critical decisions, corresponding to guidelines in 117 (93%) decisions. None of the 66 studied patients survived to hospital discharge, and 7 (11%) were organ donors.
Conclusions:
The management of avalanche victims in CA respect current guidelines regarding the critical decisions, but no patient survived in this sample. The presence of a few cases with incorrect management and potential undertreatment suggests some room for improvement.

Guidelines for Nursing Documentation II
Timely documentation is crucial to ensure continuity of care for patients. Any delays in recording or reporting medical information can result in medical errors and even adverse patient outcomes. From medication administration to diagnostic test results, every detail must be accurately and promptly documented to provide the best possible care for patients.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
