Increasing ventilation in drowning resuscitation - A cross-over randomized simulation study of ventilation during automated external defibrillator analysis pauses.

Objective: The aim of this study was to analyze the feasibility of a new resuscitation strategy in which breaths are provided during automated external defibrillator (AED) rhythm analysis, and to evaluate its impact on chest compressions (CC) quality and the peri-analysis time. Method: A randomized simulation study, comparing two cardiopulmonary resuscitations strategies, has been conducted: the standard strategy (S1) with strategy involving ventilation during AED analysis (S2). Thirty lifeguards have performed both strategies in a cross-over study design during 10 min of CPR. Results: The number of ventilations per 10 min increases from 47 (S1) to 72 (S2) (p < 0.001). This results in the delivery of an additional 17.1 L of insufflated air in S2 compared to S1 (p < 0.001). There have been no significant changes in frequency and total number of CC. These findings correspond to a reduction of the non-ventilation period from 176 s (S1) to 48 s (S2). Conclusions: This simulation study suggests that it is feasible to increase the number of ventilations during resuscitation following drowning, without affecting the quantity and quality of chest compressions. The results of this study may serve as a foundation for further investigation into optimal ventilation strategies in this context.

Is the Over-the-Head Technique an Alternative for Infant CPR Performed by a Single Rescuer? A Randomized Simulation Study with Lifeguards.

(1) Objective: The objective was to evaluate the quality of cardiopulmonary resuscitation (CPR, chest compressions and ventilations) when performed by a lone first responder on an infant victim via the over-the-head technique (OTH) with bag-mask ventilation in comparison with the standard lateral technique (LAT) position. (2) Methods: A randomized simulation crossover study in a baby manikin was conducted. A total of 28 first responders performed each of the techniques in two separate CPR tests (15:2 chest compressions:ventilations ratio), each lasting 5 min with a 15 min resting period. Quality CPR parameters were assessed using an app connected to the manikin. Those variables were related to chest compressions (CC: depth, rate, and correct CC point) and ventilation (number of effective ventilations). Additional variables included perceptions of the ease of execution of CPR. (3) Results: The median global CPR quality (integrated CC + V) was 82% with OTH and 79% with LAT (p = 0.94), whilst the CC quality was 88% with OTH and 80% with LAT (p = 0.67), and ventilation quality was 85% with OTH and 85% with LAT (p = 0.98). Correct chest release was significantly better with OTH (OTH: 92% vs. LAT: 62%, p < 0.001). There were no statistically significant differences in the remaining variables. Ease of execution perceptions favored the use of LAT over OTH. (4) Conclusions: Chest compressions and ventilations can be performed with similar quality in an infant manikin by lifeguards both with the standard recommended position (LAT) and the alternative OTH. This option could give some advantages in terms of optimal chest release between compressions. Our results should encourage the assessment of OTH in some selected cases and situations as when a lone rescuer is present and/or there are physical conditions that could impede the lateral rescue position.

Aquatic Feasibility of Limbs Application of Tourniquets (AFLAT) during a Lifeguard Water Rescue: A Simulation Pilot Study.

INTRODUCTION: Control of massive hemorrhage (MH) is a life-saving intervention. The use of tourniquets has been studied in prehospital and battlefield settings but not in aquatic environments. OBJECTIVE: The aim of this research is to assess the control of MH in an aquatic environment by analyzing the usability of two tourniquet models with different adjustment mechanisms: windlass rod versus ratchet. METHODOLOGY: A pilot simulation study was conducted using a randomized crossover design to assess the control of MH resulting from an upper extremity arterial perforation in an aquatic setting. A sample of 24 trained lifeguards performed two randomized tests: one using a windlass-based Combat Application Tourniquet 7 Gen (T-CAT) and the other using a ratchet-based OMNA Marine Tourniquet (T-OMNA) specifically designed for aquatic use on a training arm for hemorrhage control. The tests were conducted after swimming an approximate distance of 100 meters and the tourniquets were applied while in the water. The following parameters were recorded: time of rescue (rescue phases and tourniquet application), perceived fatigue, and technical actions related to tourniquet skills. RESULTS: With the T-OMNA, 46% of the lifeguards successfully stopped the MH compared to 21% with the T-CAT (P = .015). The approach swim time was 135 seconds with the T-OMNA and 131 seconds with the T-CAT (P = .42). The total time (swim time plus tourniquet placement) was 174 seconds with the T-OMNA and 177 seconds with the T-CAT (P = .55). The adjustment time (from securing the Velcro to completing the manipulation of the windlass or ratchet) for the T-OMNA was faster than with the T-CAT (six seconds versus 19 seconds; P < .001; effect size [ES] = 0.83). The perceived fatigue was high, with a score of seven out of ten in both tests (P = .46). CONCLUSIONS: Lifeguards in this study demonstrated the ability to use both tourniquets during aquatic rescues under conditions of fatigue. The tourniquet with the ratcheting-fixation system controlled hemorrhage in less time than the windlass rod-based tourniquet, although achieving complete bleeding control had a low success rate.

New communication tool for basic life support training: smart glasses. A quasi-experimental study.

AIM: To analyze the effectiveness of a teaching-learning methodology for teletraining in basic life support (BLS) based on communication through smart glasses. DESIGN: Pilot quasi-experimental non-inferiority study. PARTICIPANTS: Sixty college students. INTERVENTIONS: Randomization of the participants in: tele-training through smart glasses (SG) and traditional training (C) groups. Both training sessions were very brief (less than 8 min) and included the same BLS content. In SG, the instructor trained through a video call with smart glasses. MAIN VARIABLES OF INTEREST: The BLS protocol, the use of AED, the quality of resuscitation and the response times were evaluated. RESULTS: In most of the BLS protocol variables, the resuscitation quality and performance times, there were no statistically significant differences between groups. There were significant differences (in favor of the SG) in the assessment of breathing (SG: 100%, C: 81%; p = 0.013), the not-to-touch warning before applying the shock (SG: 79%, C: 52%; p = 0.025) and compressions with correct recoil (SG: 85%, C: 32%; p = 0.008). CONCLUSIONS: Laypeople BLS-AED brief tele-training through smart glasses could potentially be, at least, as effective as traditional training methods. In addition, smart glasses could be more advantageous than traditional teaching for certain points of the BLS protocol and chest compressions quality, probably due to the capability of real-time visualization of images which supports the BLS sequence. Augmented reality supported teaching should be considered for BLS training, although caution is required in extrapolating findings, and further in-depth studies are needed to confirm its potential role depending on concrete target populations and environments.

Clinical outcome prediction of acute neurological patients admitted to the emergency department: Sequential Organ Failure Assessment score and modified SOFA score.

Background: The aim of this study was to determine the ability of the Sequential Organ Failure Assessment score (SOFA) and modified SOFA score (mSOFA) as predictive tools for 2-day and 28-day mortality and ICU admission in patients with acute neurological pathology treated in hospital emergency departments (EDs). Methods: An observational, prospective cohort study in adults with acute neurological disease transferred by ambulance to an ED was conducted from 1 January 2019 to 31 August 2022 in five hospitals in Castilla-León (Spain). Score discrimination was assessed by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve of the score. Results: A total of 640 adult patients with neurological disease were included. For the prediction of 2-day mortality (all-cause), mSOFA presented a higher AUC than SOFA (mSOFA = 0.925 vs. SOFA = 0.902). This was not the case for 28-day mortality, for which SOFA was higher than mSOFA (mSOFA = 0.852 vs. SOFA = 0.875). Finally, ICU admission showed that SOFA was higher than mSOFA (mSOFA = 0.834 vs. SOFA = 0.845). Conclusion: Both mSOFA and SOFA presented similar predictive ability, with mSOFA being the best predictor for short-term mortality and SOFA being the best predictor for medium-term mortality, as well as for ICU admission. These results in a cohort of patients with acute neurological pathology pave the way for the use of both predictive tools in the ED. The inclusion of these tools could improve the clinical assessment and further treatment of neurological patients, who commonly present the worst outcomes.

School children brief training to save foreign body airway obstruction.

Foreign body airway obstruction (FBAO) is a relatively common emergency and a potential cause of sudden death both in children and older people; bystander immediate action will determine the victim's outcome. Although many school children's basic life support (BLS) training programs have been implemented in recent years, references to specific training on FBAO are lacking. Therefore, the aim was to assess FBAO-solving knowledge acquisition in 10-13-year-old school children. A quasi-experimental non-controlled simulation study was carried out on 564 ten-to-thirteen-year-old children from 5 schools in Galicia (Spain). Participants received a 60-min training led by their physical education teachers (5 min theory, 15 min demonstration by the teacher, and 30 min hands-on training) on how to help to solve an FBAO event. After the training session, the school children's skills were assessed in a standardized adult's progressive FBAO simulation scenario. The assessment was carried out by proficient researchers utilizing a comprehensive checklist specifically designed to address the variables involved in resolving a FBAO event according with current international guidelines. The assessment of school children's acquired knowledge during the simulated mild FBAO revealed that 62.2% of participants successfully identified the event and promptly encouraged the simulated patient to cough actively. When the obstruction progressed, its severity was recognized by 86.2% and back blows were administered, followed by abdominal thrusts by 90.4%. When the simulated victim became unconscious, 77.1% of children identified the situation and immediately called the emergency medical service and 81.1% initiated chest compressions. No significant differences in performance were detected according to participants' age.  Conclusion: A brief focused training contributes to prepare 10-13-year-old school children to perform the recommended FBAO steps in a standardized simulated patient. We consider that FBAO should be included in BLS training programs for school children. What is Known: • Kids Save Lives strategy states that school children should learn basic life support (BLS) skills because of their potential role as first responders. • This BLS training does not include content for resolving a foreign body airway obstruction (FBAO). What is New: • Following a 60-min theoretical-practical training led by physical education teachers, 10-13-year-old school children are able to solve a simulated FBAO situation. • The inclusion of FBAO content in BLS training in schools should be considered.

Trained Lifeguards Performing Pediatric Cardiopulmonary Resuscitation While Running: A Pilot Simulation Study.

The aim of this study was to compare the quality of standard infant CPR with CPR in motion (i.e., walking and running) via performing maneuvers and evacuating the infant from a beach. Thirteen trained lifeguards participated in a randomized crossover study. Each rescuer individually performed three tests of 2 min each. Five rescue breaths and cycles of 30 chest compressions followed by two breaths were performed. Mouth-to-mouth-and-nose ventilation was carried out, and chest compressions were performed using the two-fingers technique. The manikin was carried on the rescuer's forearm with the head in the distal position. The analysis variables included compression, ventilation, and CPR quality variables, as well as physiological and effort parameters. Significantly lower compression quality values were obtained in running CPR versus standard CPR (53% ± 14% versus 63% ± 15%; p = 0.045). No significant differences were observed in ventilation or CPR quality. In conclusion, lifeguards in good physical condition can perform simulated infant CPR of a similar quality to that of CPR carried out on a victim who is lying down in a fixed position.

Dispatcher-assisted BLS for lay bystanders: A pilot study comparing video streaming via smart glasses and telephone instructions.

OBJECTIVE: To determine whether dispatcher assistance via smart glasses improves bystander basic life support (BLS) performance compared with standard telephone assistance in a simulated out-of-hospital cardiac arrest (OHCA) scenario. METHODS: Pilot study in which 28 lay people randomly assigned to a smart glasses-video assistance (SG-VA) intervention group or a smartphone-audio assistance (SP-AA) control group received dispatcher guidance from a dispatcher to provide BLS in an OHCA simulation. SG-VA rescuers received assistance via a video call with smart glasses (Vuzix, Blade) connected to a wireless network, while SP-AA rescuers received instructions over a smartphone with the speaker function activated. BLS protocol steps, quality of chest compressions, and performance times were compared. RESULTS: Nine of the 14 SG-VA rescuers correctly completed the BLS protocol compared with none of the SP-AA rescuers (p = 0.01). A significantly higher number of SG-VA rescuers successfully opened the airway (13 vs. 5, p = 0.002), checked breathing (13 vs. 8, p = 0.03), correctly positioned the automatic external defibrillator pads (14 vs.6, p = 0.001), and warned bystanders to stay clear before delivering the shock (12 vs. 0, p < 0.001). No significant differences were observed for performance times or chest compression quality. The mean compression rate was 104 compressions per minute in the SG-VA group and 98 compressions per minute in the SP-AA group (p = 0.46); mean depth of compression was 4.5 cm and 4.4 cm (p = 0.49), respectively. CONCLUSIONS: Smart glasses could significantly improve dispatcher-assisted bystander performance in an OHCA event. Their potential in real-life situations should be evaluated.

Augmented reality training in basic life support with the help of smart glasses. A pilot study.

Introduction: Laypeople should be trained in basic life support and traditional and innovative methodologies may help to obtain this goal. However, there is a knowledge gap about the ideal basic life support training methods. Smart glasses could have a role facilitating laypeople learning of basic life support. Aim: To analyze the potential impact on basic life support learning of a very brief training supported by smart glasses video communication. Methods: Twelve laypeople were basic life support tele-trained by means of smart glasses by an instructor in this pilot study. During training (assisted trough smart glasses) and after the training (unassisted) participants' performance and quality of basic life support and automated external defibrillation procedure were assessed on a standardized simulated scenario. Results: After the training all participants were able to deliver good quality basic life support, with results comparable to those obtained when real time remotely guided by the instructor through the smart glasses. Mean chest compression rate was significantly higher when not guided (113 /min vs. 103 /min, p = 0.001). When not assisted, the participants spent less time delivering the sequential basic life support steps than when assisted while training. Conclusions: A very brief remote training supported by instructor and smart glasses seems to be an effective educational method that could facilitate basic life support learning by laypeople. This technology could be considered in cases where instructors are not locally available or in general in remote areas, providing basic internet connection is available. Smart glasses could also be useful for laypeople rolling-refreshers.

Assessment of over-the-head resuscitation method in an inflatable rescue boat sailing at full speed. A non-inferiority pilot study.

INTRODUCTION: Drowning is a public health problem. Interrupting the drowning process as soon as possible and starting cardiopulmonary resuscitation (CPR) can improve survival rates. Inflatable rescue boats (IRBs) are widely used worldwide to rescue drowning victims. Performing CPR in special circumstances requires adjusting the position based on the environment and space available. The aim of this study was to assess the quality of over-the-head resuscitation performed by rescuers aboard an IRB in comparison to standard CPR. METHODS: A quasi-experimental, quantitative, cross-sectional pilot study was conducted. Ten professional rescuers performed 1 min of simulated CPR on a QCPR Resuscy Anne manikin (Laerdal, Norway) sailing at 20 knots using two different techniques: 1) standard CPR (S-CPR) and 2) over-the-head CPR (OTH-CPR). Data were recorded through the APP QCPR Training (Laerdal, Norway). RESULTS: The quality of CPR was similar between S-CPR (61%) and OTH-CPR (66%), with no statistically significant differences (p = 0.585). Both the percentage of compressions and the percentage of correct ventilations did not show significant differences (p > 0.05) between the techniques. CONCLUSION: The rescuers can perform CPR maneuvers with acceptable quality in the IRB. The OTH-CPR technique did not show inferiority compared to S-CPR, making it a viable alternative when boat space or rescue conditions do not allow the conventional technique to be performed.

Are smart glasses feasible for dispatch prehospital assistance during on-boat cardiac arrest? A pilot simulation study with fishermen.

The aim of the study was to explore feasibility of basic life support (BLS) guided through smart glasses (SGs) when assisting fishermen bystanders. Twelve participants assisted a simulated out-of-hospital cardiac arrest on a fishing boat assisted by the dispatcher through the SGs. The SGs were connected to make video calls. Feasibility was assessed whether or not they needed help from the dispatcher. BLS-AED steps, time to first shock/compression, and CPR's quality (hands-only) during 2 consecutive minutes (1st minute without dispatcher feedback, 2nd with dispatcher feedback) were analyzed. Reliability was analyzed by comparing the assessment of variables performed by the dispatcher through SGs with those registered by an on-scene instructor. Assistance through SGs was needed in 72% of the BLS steps, which enabled all participants to perform the ABC approach and use AED correctly. Feasibility was proven that dispatcher's feedback through SGs helped to improve bystanders' performance, as after dispatcher gave feedback via SGs, only 3% of skills were incorrect. Comparison of on-scene instructor vs. SGs assessment by dispatcher differ in 8% of the analyzed skills: greatest difference in the "incorrect hand position during CPR" (on-scene: 33% vs. dispatcher: 0%). When comparing the 1st minute with 2nd minute, there were only significant differences in the percentage of compressions with correct depth (1st:48 ± 42%, 2nd:70 ± 31, p = 0.02). Using SGs in aquatic settings is feasible and improves BLS. CPR quality markers were similar with and without SG. These devices have great potential for communication between dispatchers and laypersons but need more development to be used in real emergencies.

Brief Training of Technical Bleeding Control Skills-A Pilot Study with Security Forces.

Uncontrolled external bleeding is a common cause of preventable death, and due to the environment in which these events often occur, e.g., in hostile environments, the state security forces are usually the first responders, and in many cases, if they are injured their partners provide the initial assistance. The tourniquet is a fast, effective, and easy-to-learn intervention, although there is a knowledge gap concerning training techniques. The objective is to evaluate the effectiveness of a bleeding control training program on a high-fidelity mannequin in a simulated critical situation in a law enforcement training environment. A quasi-experimental study was carried out with 27 members of the state security forces. They underwent brief theoretical-practical training and were evaluated via a scenario involving a critically ill patient in a hostile environment. The results showed that no member of the state security forces completed all the tourniquet placement steps, 26 (96%) prepared the tourniquet correctly, 21 (77.8%) placed it on the leg, and all the participants adjusted the band to the thickness of the injured limb and secured the windlass to the triangular flange of the device. However, only 23 (85.2%) of the participants placed it effectively. The participants, who were members of the state security forces, were able to effectively resolve a critical situation with active bleeding in a simulation scenario with a high-fidelity mannequin after completing theoretical-practical training.

Quality of Ventilations during Infant Resuscitation: A Simulation Study Comparing Endotracheal Tube with Face Mask.

Background: There are few studies that analyze ventilation volume and pressure during CPR carried out on infants. The aim of this study was to evaluate the quality of the ventilations administered using a self-inflating bag with an endotracheal tube and a face mask in manikins. Methods: a quasi-experimental simulation study with a randomized case crossover design [endotracheal tube (ET) vs. face mask (FM)] was performed. Sixty participants who were previously trained nursing students participated in the study. The estimated air volumes breathed, and the pressure generated during each ventilation were assessed and the quality of the chest compressions was recorded. Results: the ET test presented a higher percentage of ventilations that reached the lungs (100% vs. 86%; p < 0.001), with adequate volume (60% vs. 28%; p < 0.001) in comparison to FM. Both tests presented peak pressures generated in the airway greater than 30 cm H2O (ET: 22% vs. FM: 31%; p = 0.03). Conclusions: performing quality CPR ventilations on an infant model is not an easy skill for trained nursing students. Both tests presented a significant incidence of excessive peak pressure during ventilations. Specific training, focused on quality of ventilations guided by a manometer attached to the self-inflating bag, must be considered in life support training for pediatric providers.

Can a voice assistant help bystanders save lives? A feasibility pilot study chatbot in beta version to assist OHCA bystanders.

OBJECTIVE: Evaluating the usefulness of a chat bot as an assistant during CPR care by laypersons. METHODS: Twenty-one university graduates and university students naive in basic life support participated in this quasi-experimental simulation pilot trial. A version beta chatbot was designed to guide potential bystanders who need help in caring for cardiac arrest victims. Through a Question-Answering (Q&A) flowchart, the chatbot uses Voice Recognition Techniques to transform the user's audio into text. After the transformation, it generates the answer to provide the necessary help through machine and deep learning algorithms. A simulation test with a Laerdal Little Anne manikin was performed. Participants initiated the chatbot, which guided them through the recognition of a cardiac arrest event. After recognizing the cardiac arrest, the chatbot indicated the start of chest compressions for 2 min. Evaluation of the cardiac arrest recognition sequence was done via a checklist and the quality of CPR was collected with the Laerdal Instructor App. RESULTS: 91% of participants were able to perform the entire sequence correctly. All participants checked the safety of the scene and made sure to call 112. 62% place their hands on the correct compression point. A media time of 158 s (IQR: 146-189) was needed for the whole process. 33% of participants achieved high-quality CPR with a median of 60% in QCPR (IQR: 9-86). Compression depth had a median of 42 mm (IQR: 33-53) and compression rate had a median of 100 compressions/min (IQR: 97-100). CONCLUSION: The use of a voice assistant could be useful for people with no previous training to perform de out-of-hospital cardiac arrest recognition sequence. Chatbot was able to guide all participants to call 112 and to perform continuous chest compressions. The first version of the chatbot for potential bystanders naive in basic life support needs to be further developed to reduce response times and be more effective in giving feedback on chest compressions.

A Comparison between Three Different Techniques Considering Quality Skills, Fatigue and Hand Pain during a Prolonged Infant Resuscitation: A Cross-Over Study with Lifeguards.

The aim of the study was to compare the quality of CPR (Q-CPR), as well as the perceived fatigue and hand pain in a prolonged infant cardiopulmonary resuscitation (CPR) performed by lifeguards using three different techniques. A randomized crossover simulation study was used to compare three infant CPR techniques: the two-finger technique (TF); the two-thumb encircling technique (TTE) and the two-thumb-fist technique (TTF). 58 professional lifeguards performed three tests in pairs during a 20-min period of CPR. The rescuers performed compressions and ventilations in 15:2 cycles and changed their roles every 2 min. The variables of analysis were CPR quality components, rate of perceived exertion (RPE) and hand pain with numeric rating scale (NRS). All three techniques showed high Q-CPR results (TF: 86 ± 9%/TTE: 88 ± 9%/TTF: 86 ± 16%), and the TTE showed higher values than the TF (p = 0.03). In the RPE analysis, fatigue was not excessive with any of the three techniques (values 20 min between 3.2 for TF, 2.4 in TTE and 2.5 in TTF on a 10-point scale). TF reached a higher value in RPE than TTF in all the intervals analyzed (p < 0.05). In relation to NRS, TF showed significantly higher values than TTE and TTF (NRS minute 20 = TF 4.7 vs. TTE 2.5 & TTF 2.2; p < 0.001). In conclusion, all techniques have been shown to be effective in high-quality infant CPR in a prolonged resuscitation carried out by lifeguards. However, the two-finger technique is less efficient in relation to fatigue and hand pain compared with two-thumb technique (TF vs. TTF, p = 0.01).

[Descriptive analysis of triggers, outcomes and the response of the health systems of child drowning in Galicia (Spain). A 17-year retrospective study.] / Análisis descriptivo de las causas, consecuencias y respuesta de los sistemas de Salud Pública en los ahogamientos pediátricos en Galicia. Un estudio retrospectivo de 17 años.

OBJECTIVE: Drowning is one of major public health problem in childhood. The aim of this paper was to describe the characteristics, locations, interventions and outcomes of child drowning in Galicia over 17 years. METHODS: Retrospective study of 100% of data of drowning amongst children aged 0-14 in the 2004-2020 period who were attended by the 061 emergency services in Galicia (Spain) was made. The characteristics of the incident, the victim's profile, location, type of medical care given and whether the victim survived or died were analysed using the Chi Square test to compare relative frequencies, and Odds Ratio to estimate the risk. RESULTS: During the period under study, 100 child drownings were recorded. In 55%, the main cause was lack of supervision. Young children (aged 0-4) primarily drowned in pools, and pre-teens and teenagers (aged 10-14) in the sea. In 42% of the incidents, bystanders performed CPR (37% included ventilation). Emergency services took 12 minutes on average to arrive at the scene. 6% died in situ and of the rest, were taken to hospital and admitted in 47% PICU, 26% ward, 8% discharged from Accident and Emergency (43% with pulmonary oedema, 41% with supplemental oxygen, 13% with IMV/NIMV [invasive mechanical ventilation/non-invasive]). Pneumonia was the most common complication and survival to discharge was 77%. CONCLUSIONS: Small children usually drown in pools and water facilities because of lack of supervision, whereas adolescents usually drown in the sea. CPR started by bystanders and the fast response of emergency services contributed to a high rate of survival. A large amount of data was lost during the process: accurate, standardized coding of drowning is necessary.

OBJETIVO: El ahogamiento es un importante problema de Salud Pública en la etapa infantil. El objetivo de este trabajo fue describir las características, localizaciones, intervenciones y resultados del ahogamiento pediátrico en Galicia durante 17 años. METODOS: Se realizó un estudio retrospectivo del 100% de los datos de ahogamiento de personas entre 0 y 14 años de edad del año 2004 a 2020, que fueran atendidos por los servicios de emergencias de Galicia 061. Se analizaron las características del incidente, perfil de la víctima, localización, tipo de asistencia sanitaria recibida y supervivencia respecto a muerte mediante el test Chi Cuadrado para comparar frecuencias relativas, y Odds Ratio para estimar el riesgo. RESULTADOS: Se registraron 100 ahogamientos pediátricos. En el 55% la principal causa fue la falta de supervisión. Los niños y niñas de 0-4 años se ahogaban mayoritariamente en piscinas, mientras que los/las adolescentes (10-14 años) en playas. En el 42% de los incidentes el testigo hizo reanimación cardiopulmonar (un 37% incluyó ventilaciones). Los servicios de emergencia tardaron 12 minutos de media en llegar. Un 6% falleció in situ y el resto fueron trasladados al hospital e ingresaron el 47% en UCI, 26% en planta, y 8% cursaron alta en Urgencias (43% con edema pulmonar, 41% con oxígeno suplementario, 13% con VMI/VMNI [ventilación mecánica invasiva/no invasiva]). La neumonía fue una complicación habitual y la supervivencia al alta fue del 77%. CONCLUSIONES: Los niños/as más pequeños se ahogan habitualmente en instalaciones acuáticas por falta de supervisión mientras que los/las adolescentes se suelen ahogar en playas marítimas. El inicio de la reanimación por parte de testigos y la rápida respuesta de los servicios de emergencias se asocia a una alta tasa de supervivencia. Numerosos datos fueron perdidos durante el proceso por lo que es necesaria una correcta y unificada codificación del ahogamiento.

Comparison of Nine Early Warning Scores for Identification of Short-Term Mortality in Acute Neurological Disease in Emergency Department.

(1) Background: The aim was screening the performance of nine Early Warning Scores (EWS), to identify patients at high-risk of premature impairment and to detect intensive care unit (ICU) admissions, as well as to track the 2-, 7-, 14-, and 28-day mortality in a cohort of patients diagnosed with an acute neurological condition. (2) Methods: We conducted a prospective, longitudinal, observational study, calculating the EWS [Modified Early Warning Score (MEWS), National Early Warning Score (NEWS), VitalPAC Early Warning Score (ViEWS), Modified Rapid Emergency Medicine Score (MREMS), Early Warning Score (EWS), Hamilton Early Warning Score (HEWS), Standardised Early Warning Score (SEWS), WHO Prognostic Scored System (WPSS), and Rapid Acute Physiology Score (RAPS)] upon the arrival of patients to the emergency department. (3) Results: In all, 1160 patients were included: 808 patients were hospitalized, 199 cases (17%) required ICU care, and 6% of patients died (64 cases) within 2 days, which rose to 16% (183 cases) within 28 days. The highest area under the curve for predicting the need for ICU admissions was obtained by RAPS and MEWS. For predicting mortality, MREMS obtained the best scores for 2- and 28-day mortality. (4) Conclusions: This is the first study to explore whether several EWS accurately identify the risk of ICU admissions and mortality, at different time points, in patients with acute neurological disorders. Every score analyzed obtained good results, but it is suggested that the use of RAPS, MEWS, and MREMS should be preferred in the acute setting, for patients with neurological impairment.

Infant Cardiopulmonary Resuscitation Quality While Walking Fast: A Simulation Study.

OBJECTIVE: This study focuses on the characteristics (feasibility, resuscitation quality, and physical demands) of infant cardiopulmonary resuscitation (CPR) on the forearm during fast walking, performed by a trained lay rescuer. METHODS: Twenty-one university students from the infant education degree participated in a randomized crossover simulation study to compare a standard pediatric CPR versus a walking pediatric CPR with a manikin on the rescue forearm. Each rescuer performed 2 resuscitation tests of 2 minutes on the infant manikin. Cardiopulmonary resuscitation, physiological, and perceived effort variables were measured. RESULTS: The quality of chest compressions was higher in standard pediatric CPR than in walking pediatric CPR (72% vs 51%; P < 0.001) and overall CPR quality (59% vs 49%; P = 0.02). There were no differences between ventilation quality (47% vs 46%). Walking pediatric CPR presented a higher percentage of maximum heart rate (52% vs 69%; P < 0.001) and perceived exertion rate (2 vs 5; P < 0.001). Participants walked an average of 197 m during the test. CONCLUSIONS: In conclusion, pediatric walking CPR is feasible although it represents a slight quality decrease in a simulation infant CPR setting. The option "CPR while walking fast to a safe place" seems to be suitable in terms of safety both for the victim and the rescuer, as well as CPR quality in special circumstances.

Training frequency for educating schoolchildren in basic life support: very brief 4-month rolling-refreshers versus annual retraining-a 2-year prospective longitudinal trial.

OBJECTIVE: To compare the effectiveness of 4-month rolling-refreshers and annual retraining in basic life support (BLS) on a sample of schoolchildren. DESIGN: Prospective longitudinal trial. SETTING AND PARTICIPANTS: Four hundred and seventy-two schoolchildren (8-12 years old). INTERVENTIONS: Schoolchildren were instructed in BLS and then split into the following three groups: control group (CG), standard group (SG) and rolling-refresher group (RRG). Their BLS skills were assessed within 1 week (T1) and 2 years later (T2). Moreover, CG did not receive any additional training; SG received one 50 min retraining session 1 year later; RRG participated in very brief (5 min) rolling-refreshers that were carried out every 4 months. PRIMARY AND SECONDARY OUTCOMES: Hands-on skills of BLS sequence and cardiopulmonary resuscitation. RESULTS: BLS sequence performance was similar in all groups at T1, but SG and RRG followed the steps of the protocol in more proportion than CG at T2. When compared at T2, RRG showed higher proficiency than SG in checking safety, checking response, opening the airway and alerting emergency medical services. In addition, although the mean resuscitation quality was low in all groups, RRG participants reached a higher percentage of global quality cardiopulmonary resuscitation (CG: 16.4±24.1; SG: 25.3±28.8; RRG: 29.9%±29.4%), with a higher percentage of correct chest compressions by depth (CG: 3.9±11.8; SG: 10.8±22.7; RRG: 15.5±26.1 mm). CONCLUSIONS: In 8-to-12-year-old schoolchildren, although annual 50 min retraining sessions help to maintain BLS performance, 4-month very brief rolling-refreshers were shown to be even more effective. Thus, we recommend implementing baseline BLS training at schools, with subsequently brief rolling-refreshers.

Teaching Basic Life Support to 5- to 8-Year-Old Children: A Cluster Randomized Trial.

OBJECTIVE: We aimed to compare traditional basic life support (BLS) education with specific and innovative educative didactic material that has been previously designed and validated. METHODS: Fifteen classes of schoolchildren aged 5 to 8 years (n = 237) were randomly assigned to 4 groups in which different didactic and complementary materials were used: (1) the Rescube tool with a cuddly toy (n = 61), (2) the Endless Book tool with a cuddly toy (n = 74), (3) traditional teaching with a cuddly toy (n = 46), and (4) traditional teaching with a manikin (n = 55). The BLS sequence was assessed at baseline (T0). After that, children took part in a one-hour theory and practice session in their assigned training modality. BLS sequence was assessed again within one week (T1) and after one month (T2). RESULTS: The 4 modalities were successful in improving children's skills when comparing T0 with both T1 and T2 (P < .05). At T2, more schoolchildren remembered the complete BLS sequence after using the Rescube (75%) compared with the number of schoolchildren who remember the complete BLS sequence after using the Endless Book (53%), a manikin (42%), or a cuddly toy (13%) (P < .05). A higher proportion of participants who used the Rescube correctly performed all the BLS steps analyzed compared with those who used only the manikin or a cuddly toy during the learning phase. The Endless Book was also more effective except for learning to check consciousness and breathing. CONCLUSION: Better BLS learning and knowledge retention outcomes were achieved by using our specific and adapted didactic materials (Rescube and Endless Book). These new educational tools have the potential to substantially support BLS school education programs.
