The 'chain of survival'-including early call for help, early cardiopulmonary resuscitation (CPR) and early defibrillation-represents the most beneficial approach for favourable patient outcome after out-of-hospital cardiac arrest (OHCA). Despite increasing numbers of publicly accessible automated external defibrillators (AED) and interventions to increase public awareness for basic life support (BLS), the number of their use in real-life emergency situations remains low. In this prospective population-based cross-sectional study, a total of 501 registered inhabitants of Vienna (Austria) were randomly approached via telephone calls between 08/2014 and 09/2014 and invited to answer a standardized questionnaire in order to identify public knowledge and awareness of BLS and AED-use. We found that more than 52 percent of participants would presume OHCA correctly and would properly initiate BLS attempts. Of alarming importance, only 33 percent reported that they would be willing to perform CPR and 50 percent would use an AED device. There was a significantly lower willingness to initiate BLS attempts (male: 40% vs. female: 25%; OR: 2.03 [95%CI: 1.39-2.98]; p<0.001) and to use an AED device (male: 58% vs. female: 44%; OR: 1.76 [95%CI: 1.26-2.53]; p = 0.002) in questioned female individuals compared to their male counterparts. Interestingly, we observed a strongly decreasing level of knowledge and willingness for BLS attempts (-14%; OR: 0.72 [95%CI: 0.57-0.92]; p = 0.027) and AED-use (-19%; OR: 0.68 [95%CI: 0.54-0.85]; p = 0.001) with increasing age. We found an overall poor knowledge and awareness concerning BLS and the use of AEDs among the Viennese population. Both female and elderly participants reported the lowest willingness to perform BLS and use an AED in case of OHCA. Specially tailored programs to increase awareness and willingness among both the female and elderly community need to be considered for future educational interventions.

To determine which of two facemask grip techniques for two-person facemask ventilation was more effective in novice clinicians, the traditional E-C clamp (EC) grip or a thenar eminence (TE) technique. Prospective, randomized, crossover comparison study. Operating room of a university hospital. 60 novice clinicians (medical and paramedic students). Subjects were assigned to perform, in a random order, each of the two mask-grip techniques on consenting ASA physical status 1, 2, and 3 patients undergoing elective general anesthesia while the ventilator delivered a fixed 500 mL tidal volume (VT). In a crossover manner, subjects performed each facemask ventilation technique (EC and TE) for one minute (12 breaths/min). The primary outcome was the mean expired VT compared between techniques. As a secondary outcome, we examined mean peak inspiratory pressure (PIP). The TE grip provided greater expired VT (379 mL vs 269 mL), with a mean difference of 110 mL (P < 0.0001; 95% CI: 65, 157). Using the EC grip first had an average VT improvement of 200 mL after crossover to the TE grip (95% CI: 134, 267). When the TE grip was used first, mean VTs were greater than for EC by 24 mL (95% CI: -25, 74). When considering only the first 12 breaths delivered (prior to crossover), the TE grip resulted in mean VTs of 339 mL vs 221 mL for the EC grip (P = 0.0128; 95% CI: 26, 209). There was no significant difference in PIP values using the two grips: the TE mean (SD) was 14.2 (7.0) cm H2O, and the EC mean (SD) was 13.5 (9.0) cm H2O (P = 0.49). The TE facemask ventilation grip results in improved ventilation over the EC grip in the hands of novice providers.

Background Withdrawal of life-sustaining measures is a common event in the intensive care unit yet it involves a complex balance of medical, legal and ethical considerations. Very few healthcare providers have been specifically trained to withdraw life-sustaining measures, and no comprehensive guidelines exist to help ensure clinicians deliver the highest quality of care to patients and families. Hence, we sought to develop guidelines for the process of withdrawing life-sustaining measures in the clinical setting. Methods We convened an interdisciplinary group of ICU care providers from the Canadian Critical Care Society and the Canadian Association of Critical Care Nurses, and used a modified Delphi process to answer key clinical and ethical questions identified in the literature. Results A total of 39 experienced clinicians completed the initial workshop, and 36 were involved in the subsequent Delphi rounds. The group developed a series of guidelines to address (1) preparing for withdrawal of life-sustaining measures; (2) assessment of distress; (3) pharmaceutical management of distress; and (4) discontinuation of life-sustaining measures and monitoring. The group achieved consensus on all aspects of the guidelines after the third Delphi round. Conclusion We present these guidelines to help physicians provide high-quality end of life (EOL) care in the ICU. Future studies should address their effectiveness from both critical care team and family perspectives.

ObjectiveTo investigate the level of basic life support (BLS) skill retention of medical interns 6 and 12 months after BLS education and analyse the correlation between clinical experience of cardiopulmonary resuscitation (CPR) and BLS skill retention.Materials and methodsThe baseline performance of BLS skills in medical doctors during their internship was tested immediately after the BLS provider course. The subjects were divided into two groups, which were tested using the same method after 6 months or after 12 months. Data on the subjects' CPR experience were collected through CPR records—specifically, the number of CPR experiences and the feedback given by the CPR team leaders. To evaluate BLS skill retention, baseline BLS skill performance was compared with the skill performances measured after 6 or 12 months.ResultsFifty-six subjects were enrolled in the 6 month group and 36 in the 12 month group. For non-compression skills, the points for skills declined from 12 to 6 points in the 6 month group and from 12 to 6 points in the 12 month group and the declines in both groups were statistically significant. For compression skills, in the 12 month group, the hands-off time improved from 9.9 s to 8.7 s, with statistical significance. In the multivariate linear regression test, the number of times feedback was given had a statistical relationship with improvement in hands-off time in the 12 month group (coefficient 0.58, 95% CI 0.12 to 1.05).ConclusionsIn medical doctors, the compression skills were well preserved, but the retention of non-compression skills was poor.

Emergency pediatric life support (EPLS) of children infected with transmissible respiratory diseases requires adequate respiratory protection for medical first responders. Conventional air-purifying respirators (APR) and modern loose-fitting powered air-purifying respirator-hoods (PAPR-hood) may have a different impact during pediatric resuscitation and therefore require evaluation. This study investigated the influence of APRs and PAPR-hoods during simulated pediatric cardiopulmonary resuscitation. Study design was a randomized, controlled, crossover study. Sixteen paramedics carried out a standardized EPLS scenario inside an ambulance, either unprotected (control) or wearing a conventional APR or a PAPR-hood. Treatment times and wearer comfort were determined and compared. All paramedics completed the treatment objectives of the study arms without adverse events. Study subjects reported that communication, dexterity and mobility were significantly better in the APR group, whereas the heat-build-up was significantly less in the PAPR-hood group. Treatment times compared to the control group did not significantly differ for the APR group but did with the PAPR-hood group (261±12 seconds for the controls, 275±9 seconds for the conventional APR and 286±13 seconds for the PAPR-hood group, P < .05. APRs showed a trend to better treatment times compared to PAPR-hoods during simulated pediatric cardiopulmonary resuscitation. Study participants rated mobility, ease of communication and dexterity with the tight-fitting APR system significantly better compared to the loose-fitting PAPR-hood.

Abstract Many patients who develop incapacitating illness have not expressed clear treatment preferences. Therefore, surrogate decision makers are asked to make judgments about what treatment pathway is most consistent with the patient’s values. Surrogates often struggle with such decisions. The difficulty arises because answering the seemingly straightforward question, “What do you think the patient would choose?” is emotionally, cognitively, and morally complex. There is little guidance for clinicians to assist families in constructing an authentic picture of the patient’s values and applying them to medical decisions, in part because current models of medical decision making treat the surrogate as the expert on the patient’s values and the physician as the expert on technical medical considerations. However, many surrogates need assistance in identifying and working through the sometimes conflicting values relevant to medical decisions near the end of life. We present a framework for clinicians to help surrogates overcome the emotional, cognitive, and moral barriers to high-quality surrogate decision making for incapacitated patients.

Sustained intracranial hypertension and acute brain herniation are “brain codes,” signifying catastrophic neurological events that require immediate recognition and treatment to prevent irreversible injury and death. As in cardiac arrest, a brain code mandates the organized implementation of a stepwise management algorithm. The goal of this Emergency Neurological Life Support protocol is to implement an evidence-based, standardized approach to the evaluation and management of patients with intracranial hypertension and/or herniation.

This document serves as a guide and an educational tool for all members of intensive care unit (ICU) multidisciplinary teams and those involved in end-of-life (EOL) decisionmaking. It aims to improve the understanding of ICU EOL issues and to provide guidance to facilitate the process of selecting a course of action. Accordingly, this document can be adopted, or adapted, for local use in accordance with legislation, provincial College statements/guidelines, or institutional requirements/policies.

Airway management and ventilation are central to the resuscitation of the neurologically ill. These patients often have evolving processes that threaten the airway and adequate ventilation. Furthermore, intubation, ventilation, and sedative choices directly affect brain perfusion. Therefore, Airway, Ventilation, and Sedation was chosen as an Emergency Neurological Life Support protocol. Topics include airway management, when and how to intubate with special attention to hemodynamics and preservation of cerebral blood flow, mechanical ventilation settings and the use of sedative agents based on the patient’s neurological status.

Sy and Ross present several facts about air ambulance transport. Air ambulances make access to care and health outcomes in rural communities more equitable. In Ontario, air ambulances link remote First Nations communities to specialized hospital services, with 9.2 to 9.5 air transports per 100 on-reserve population annually, compared with 7.5 ground transports per 100 population for the whole province. Transportation by air ambulance has been shown to reduce the mortality rate from rural trauma in Nova Scotia compared with ground ambulances, and plays a crucial role in integrating health care services in remote Canadian communities.
