First responder systems can stay operational under pandemic conditions: results of a European survey during the COVID-19 pandemic

Background Dispatching first responders (FR) to out-of-hospital cardiac arrest in addition to the emergency medical service has shown to increase survival. The promising development of FR systems over the past years has been challenged by the outbreak of COVID-19. Whilst increased numbers and worse outcomes of cardiac arrests during the pandemic suggest a need for expansion of FR schemes, appropriate risk management is required to protect first responders and patients from contracting COVID-19. This study investigated how European FR schemes were affected by the pandemic and what measures were taken to protect patients and responders from COVID-19. Methods To identify FR schemes in Europe we conducted a literature search and a web search. The schemes were contacted and invited to answer an online questionnaire during the second wave of the pandemic (December 2020/ January 2021) in Europe. Results We have identified 135 FR schemes in 28 countries and included responses from 47 FR schemes in 16 countries. 25 schemes reported deactivation due to COVID-19 at some point, whilst 22 schemes continued to operate throughout the pandemic. 39 schemes communicated a pandemic-specific algorithm to their first responders. Before the COVID-19 outbreak 20 FR systems did not provide any personal protective equipment (PPE). After the outbreak 19 schemes still did not provide any PPE. The majority of schemes experienced falling numbers of accepted call outs and decreasing registrations of new volunteers. Six schemes reported of FR having contracted COVID-19 on a mission. Conclusions European FR schemes were considerably affected by the pandemic and exhibited a range of responses to protect patients and responders. Overall, FR schemes saw a decrease in activity, which was in stark contrast to the high demand caused by the increased incidence and mortality of OHCA during the pandemic. Given the important role FR play in the chain of survival, a balanced approach upholding the safety of patients and responders should be sought to keep FR schemes operational

Comparing suction rates of novel DuCanto catheter against Yankauer and standard suction catheter using liquids of different viscosity-a technical simulation

Purpose Aspiration is a feared complication that may occur during airway management, and can significantly contribute to morbidity and mortality. Availability of a suctioning device with a suction catheter capable of clearing the airway is mandatory for airway management. However, suction performance may be significantly different amongst different suction catheters. The aim of this study was to compare suction rates of a standard 14 Ch suction catheter (SC), a Yankauer catheter (Y) and a DuCanto catheter (DC) using 4 fluids with different viscosity. Methods In this simulation trial, 4 preparations with standardized viscosity were prepared using a Xanthane-based medical fluid thickener. Lowest viscosity was achieved using tap water without thickener, syrup-like viscosity was achieved by adding 10 g per liter tap water, honey-like viscosity was achieved by adding 20 g per liter, and a pudding-like viscosity was achieved by adding 30 g of thickening powder per liter tap water. Each preparation was suctioned for 15 s with the three different suctioning devices. Measurements were repeated four times. The amount of removed preparation by suctioning was measured using a tared scale. Results Suction rates for water were 580 +/- 34 mg for SC, 888 +/- 5 mg for Y and 1087 +/- 15 for DC; for syrup-like viscosity it was 383 +/- 34(SC) vs. 661 +/- 64(Y) vs. 935 +/- 42(DC); for honey-like viscosity it was 191 +/- 21(SC) vs. 426 +/- 34(Y) vs. 590 +/- 68(DC); and for pudding-like viscosity 74 +/- 13(SC) vs. 164 +/- 6(Y) vs. 211 +/- 8(DC). Conclusion Suctioning liquids of different viscosity, the new DuCanto catheter was more effective than the Yankauer catheter that was more effective than a standard suctioning catheter. The relative superiority of the DuCanto was highest in fluids with high viscosity

CPR-related cognitive activity, consciousness, awareness and recall, and its management: A scoping review

Background: There are increasing numbers of reports of cognitive activity, consciousness, awareness and recall related to cardiopulmonary resuscitation (CPR) and interventions such as the use of sedative and analgesic drugs during CPR. Objectives: This scoping review aims to describe the available evidence concerning CPR-related cognitive activity, consciousness, awareness and recall and interventions such as the use of sedative and analgesic drugs during CPR. Methods: A literature search was conducted of Medline, Embase and CINAHL from inception to 21 October 2021. We included case studies, observational studies, review studies and grey literature. Results: We identified 8 observational studies including 40,317 patients and 464 rescuers, and 26 case reports including 33 patients. The reported prevalence of CPR-induced consciousness was between 0.23% to 0.9% of resuscitation attempts, with 48-59% of experienced professional rescuers surveyed estimated to have observed CPR-induced consciousness. CPR-induced consciousness is associated with professional rescuer CPR, witnessed arrest, a shockable rhythm, increased return of spontaneous circulation (ROSC), and survival to hospital discharge when compared to patients without CPR-induced consciousness. Few studies of sedation for CPR-induced consciousness were identified. Although local protocols for treating CPR-induced consciousness exist, there is no widely accepted guidance. Conclusions: CPR-related cognitive activity, consciousness, awareness and recall is uncommon but increasingly reported by professional rescuers. The data available was heterogeneous in nature and not suitable for progression to a systematic review process. Although local treatment protocols exist for management of CPR-induced consciousness, there are no widely accepted treatment guidelines. More studies are required to investigate the management of CPR-induced consciousness

KIDS SAVE LIVES-Three years of implementation in Europe

KIDS SAVE LIVES in schools: cross-sectional survey of schoolteachers

Training schoolchildren in basic life support (BLS) is strongly recommended to effectively increase bystander cardiopulmonary resuscitation (CPR) rates. Paediatricians and other health staff members used to be involved in BLS training, but the wide dissemination of BLS skills would need additional support; as a solution, schoolteachers might have enough knowledge necessary to help to achieve this goal. The aim of this cross-sectional survey study, which involved 3423 schoolteachers, was to evaluate the knowledge related to first aid (FA) and BLS of schoolteachers in Spain. In addition, the study aimed to evaluate the content taught to the schoolchildren regarding FA and teachers' attitudes towards teaching FA. Three-quarters of the surveyed schoolteachers reported knowing FA, and 17% reported teaching it. The emergency medical telephone number and CPR were the subjects taught most often by schoolteachers. However, the schoolteachers demonstrated a lack of knowledge in the identification of cardiac arrest and in CPR. Ninety-eight percent of the respondents agreed with including FA training in schools and as part of university degree programmes and supported the KIDS SAVE LIVES statement. Teaching FA was a positive predictor to be willing to perform CPR (OR: 1.7; 95% CI 1.32-2.31) and to use a defibrillator (OR: 1.4; 95% CI 1.10-1.67). Conclusions: Schoolteachers are willing to teach FA in schools. However, more training and specific curricula are needed to increase the quality of schoolchildren's CPR training. The training of schoolteachers in CPR might be the foundation for the sustainable transfer of CPR-related knowledge to schoolchildren. Therefore, the inclusion of FA and BLS in university degree programmes seems to be essential. What is Known: Bystander cardiopulmonary resuscitation rates are associated with improved survival rates. Resuscitation training in schools increases the bystander cardiopulmonary resuscitation rate. What is New: Schoolteachers are willing to teach basic life support, but they need more and better training. Schoolteachers agreed with the inclusion of first aid training in schools and university degree programmes aimed at training teachers/undergraduate teaching degrees
