RESUMO
Aim: Recent emergence of airway clearance devices (ACDs) as a treatment alternative for foreign body airway obstructions (FBAO) lacks substantial evidence on efficacy and safety. This study aimed to assess pediatric residents' knowledge and skills in managing a simulated pediatric choking scenario, adhering to recommended protocols, and using LifeVac© and DeCHOKER© ACDs. Methods: Randomized controlled simulation trial, in which 60 pediatric residents from 3 different hospitals (median age 27 [25.0-29.9]; 76.7% female) were asked to solve an unannounced pediatric simulated choking scenario using three interventions to manage (randomized order): 1) following the recommended protocol of the European Resuscitation Council (encouraging to cough or combination of back blows and abdominal thrusts); 2) using LifeVac©; and 3) using DeCHOKER©. A Little Anne QCPR™ manikin (Laerdal Medical) was used. The variable compliance rate (%) was calculated according to the correct/incorrect execution of the steps constituting the proper actions for each test. Results: Participants demonstrated a correct compliance rate only ranging between 50-75% in following the recommended protocol for managing partial FBAO progressing to severe. Despite unfamiliarity with the ACDs, pediatric residents achieved rates between 75% and 100%, with no significant difference noted between the two devices (p = 0.173). Both scenarios were successfully resolved in under a minute, with LifeVac© demonstrating a significantly shorter response time compared to DeCHOKER© (39.2 [30.4-49.1] vs. 45.1s [33.7-59.2], p = 0.010). Conclusions: Only a minority of pediatric residents were able to adhere to the recommended FBAO protocol, whereas 70% of them were able to adequately use the ACDs. However, since a significant proportion could not, it seems that ACDs themselves do not address all issues.
RESUMO
Fundamental movement skills (FMS), considered as building blocks of movement, have received growing interest due to their significant impact on both present and future health. FMS are categorized into locomotor, object control and stability skills. While there has been extensive research on assessing the proficiency and reliability of locomotor and object control skills, stability skills have received comparatively less attention. For this reason, this study aimed to assess the test-retest, intrarater and interrater reliability of five stability skills included in the Alfamov app. The performance of eighty-four healthy primary school children (60.8% girls), aged 6 to 12 years (mean ± standard deviation of 8.7 ± 1.8 years), in five stability skills was evaluated and scored by four raters, including two experts and two novices. The Alfamov tool, integrating various process-oriented tests, was used for the assessment. Reliability analyses were conducted through the computation of the intraclass correlation coefficient (ICC) along with the corresponding 95% confidence intervals. Good-to-excellent intrarater reliability, excellent interrater reliability and moderate-to-good reliability in the test-retest were achieved. The results proved that Alfamov is a robust test for evaluating stability skills and can be suitable for use by different professionals with less experience in assessing children's motor competence.
RESUMO
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.

Aim: To implement small methodological changes in basic life support (BLS) training to reduce unnecessary pauses during automated external defibrillator (AED) use. Methods: One hundred and two university students with no BLS knowledge were randomly allocated into three groups (control and 2 experimental groups). Both experimental groups received a two-hour BLS training. While the contents were identical in both groups, in one of them the reduction of no-flow time was focused on (focused no-flow group). The control group did not receive any training. Finally, all of them were evaluated in the same out-of-hospital cardiac arrest simulated scenario. The primary endpoint was the compression fraction. Results: Results from 78 participants were analysed (control group: 19; traditional group: 30; focused no-flow group: 29). The focused no-flow group achieved higher percentages of compression fraction (median: 56.0, interquartile rank (IQR): 53.5-58.5) than the traditional group (44.0, IQR: 42.0-47.0) and control group (52.0, IQR: 43.0-58.0) in the complete scenario. Participants from the control group performed compression-only cardiopulmonary resuscitation (CPR), while the other groups performed compression-ventilation CPR. CPR fraction was calculated, showing the fraction of time in which the participants were performing resuscitation manoeuvres. In this case, the focused no-flow group reached higher percentages of CPR fraction (77.6, IQR: 74.4-82.4) than the traditional group (61.9, IQR: 59.3-68.1) and the control group (52.0, IQR: 43.0-58.0). Conclusions: Laypeople having automated external defibrillation training focused on acting in anticipation of the AED prompts contributed to a reduction in chest compression pauses during an OHCA simulated scenario.
RESUMO
BACKGROUND: The brand-new anti-choking devices (LifeVac® and DeCHOKER®) have been recently developed to treat Foreign Body Airway Obstruction (FBAO). However, the scientific evidence around these devices that are available to the public is limited. Therefore, this study aimed to assess the ability to use the LifeVac® and DeCHOKER® devices in an adult FBAO simulated scenario, by untrained health science students. METHODS: Forty-three health science students were asked to solve an FBAO event in three simulated scenarios: 1) using the LifeVac®, 2) using the DeCHOKER®, and 3) following the recommendations of the current FBAO protocol. A simulation-based assessment was used to analyze the correct compliance rate in the three scenarios based on the correct execution of the required steps, and the time it took to complete each one. RESULTS: Participants achieved correct compliance rates between 80-100%, similar in both devices (p = 0.192). Overall test times were significantly shorter with LifeVac® than DeCHOKER® device (36.6 sec. [31.9-44.4] vs. 50.4 s [36.7-66.9], p < 0.001). Regarding the recommended protocol, a 50% correct compliance rate was obtained in those with prior training vs. 31.3% without training, (p = 0.002). CONCLUSIONS: Untrained health science students are able to quickly and adequately use the brand-new anti-choking devices but have more difficulties in applying the current recommended FBAO protocol.

Children's motor competence (MC) was negatively affected by the COVID-19 pandemic; however, possible chronic effects have not been studied. Therefore, the aim of this study was to examine the possible impact of the forced lack of physical activity (PA) during the COVID-19 lockdown on children's MC two years later. The motor competence of sixty-seven healthy children (7.4−12.2 years old) was assessed using the Motor Competence Assessment (MCA). All participants completed the MCA tests at two different moments (before and after the COVID-19 lockdown), four years apart. The mean values after the COVID-19 lockdown for all participants on the subscales and on the Total MCA are lower, but no significant changes were found when controlling for gender and age (p > 0.05 in all analyses). However, a significant decrease was found in the Locomotor subscale in boys (p = 0.003). After dividing the participants into three age groups, the youngest also suffered a decrease in the Locomotor subscale (p < 0.001) and their Total MCA (p = 0.04). In addition, those participants who had a higher MC at baseline decreased their scores for the Locomotor (p < 0.001) and Manipulative (p < 0.001) subscales, and for the Total MCA (p < 0.001). In conclusion, the younger children and the more motor proficient did not fully recover from the negative effects of the pandemic lockdown after two years.
RESUMO
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.

Previous pilot experience has shown the ability of visually impaired and blind people (BP) to learn basic life support (BLS), but no studies have compared their abilities with blindfolded people (BFP) after participating in the same instructor-led, real-time feedback training. Twenty-nine BP and 30 BFP participated in this quasi-experimental trial. Training consisted of a 1 h theoretical and practical training session with an additional 30 min afterwards, led by nurses with prior experience in BLS training of various collectives. Quantitative quality of chest compressions (CC), AED use and BLS sequence were evaluated by means of a simulation scenario. BP's median time to start CC was less than 35 s. Global and specific components of CC quality were similar between groups, except for compression rate (BFP: 123.4 + 15.2 vs. BP: 110.8 + 15.3 CC/min; p = 0.002). Mean compression depth was below the recommended target in both groups, and optimal CC depth was achieved by 27.6% of blind and 23.3% of blindfolded people (p = 0.288). Time to discharge was significantly longer in BFP than BP (86.0 + 24.9 vs. 66.0 + 27.0 s; p = 0.004). Thus, after an adapted and short training program, blind people were revealed to have abilities comparable to those of blindfolded people in learning and performing the BLS sequence and CC.

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.

The Test of Gross Motor Development (TGMD) is one of the most common tools for assessing the fundamental movement skills (FMS) in children between 3 and 10 years. This study aimed to examine the intra-rater and inter-rater reliability of the TGMD-3rd Edition (TGMD-3) between expert and novice raters using live and video assessment. Five raters [2 experts and 3 novices (one of them BSc in Physical Education and Sport Science)] assessed and scored the performance of the TGMD-3 of 25 healthy children [Female: 60%; mean (standard deviation) age 9.16 (1.31)]. Schoolchildren were attending at one public elementary school during the academic year 2019-2020 from Santiago de Compostela (Spain). Raters scored each children performance through two viewing moods (live and slow-motion). The ICC (Intraclass Correlation Coefficient) was used to determine the agreement between raters. Our results showed moderate-to-excellent intra-rater reliability for overall score and locomotor and ball skills subscales; moderate-to-good inter-rater reliability for overall and ball skills; and poor-to-good for locomotor subscale. Higher intra-rater reliability was achieved by the expert raters and novice rater with physical education background compared to novice raters. However, the inter-rater reliability was more variable in all the raters regardless of their experience or background. No significant differences in reliability were found when comparing live and video assessments. For clinical practice, it would be recommended that raters reach an agreement before the assessment to avoid subjective interpretations that might distort the results.

INTRODUCTION: On-boat resuscitation can be applied by lifeguards in an inflatable rescue boat (IRB). Due to Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-COV-2) and recommendations for the use of personal protective equipment (PPE), prehospital care procedures need to be re-evaluated. The objective of this study was to determine how the use of PPE influences the amount of preparation time needed before beginning actual resuscitation and the quality of cardiopulmonary resuscitation (CPR; QCPR) on an IRB. METHODS: Three CPR tests were performed by 14 lifeguards, in teams of two, wearing different PPE: (1) Basic PPE (B-PPE): gloves, a mask, and protective glasses; (2) Full PPE (F-PPE): B-PPE + a waterproof apron; and (3) Basic PPE + plastic blanket (B+PPE). On-boat resuscitation using a bag-valve-mask (BVM) and high efficiency particulate air (HEPA) filter was performed sailing at 20km/hour. RESULTS: Using B-PPE takes less time and is significantly faster than F-PPE (B-PPE 17 [SD = 2] seconds versus F-PPE 69 [SD = 17] seconds; P = .001), and the use of B+PPE is slightly higher (B-PPE 17 [SD = 2] seconds versus B+PPE 34 [SD = 6] seconds; P = .002). The QCPR remained similar in all three scenarios (P >.05), reaching values over 79%. CONCLUSION: The use of PPE during on-board resuscitation is feasible and does not interfere with quality when performed by trained lifeguards. The use of a plastic blanket could be a quick and easy alternative to offer extra protection to lifeguards during CPR on an IRB.

Although drowning is a common phenomenon, the behaviour of drowning persons is poorly understood. The purpose of this study is to provide a quantitative and qualitative analysis of this behaviour. This was an observational study of drowning videos observed by 20 international experts in the field of water safety. For quantitative analysis, each video was analysed with Lince observation software by four participants. A Nominal Group Technique generated input for the qualitative analysis and the two principal investigators conducted a post-hoc analysis. A total of 87.5% of the 23 videos showed drowning in swimming pools, 50% of the drowned persons were male, and 58.3% were children or teenagers. Nineteen persons were rescued before unconsciousness and showed just the beginning of downing behaviour. Another five were rescued after unconsciousness, which allowed the observation of their drowning behaviour from the beginning to the end. Significant differences were found comparing both groups regarding the length of disappearances underwater, number, and length of resurfacing (resp. p = 0.003, 0.016, 0.005) and the interval from the beginning of the incident to the rescue (p = 0.004). All persons drowned within 2 min. The qualitative analysis showed previously suggested behaviour patterns (immediate disappearance n = 5, distress n = 6, instinctive drowning response n = 6, climbing ladder motion n = 3) but also a striking new pattern (backward water milling n = 19). This study confirms previous assumptions of drowning behaviour and provides novel evidence-based information about the large variety of visible behaviours of drowning persons. New behaviours, which mainly include high-frequency resurfacing during a struggle for less than 2 min and backward water milling, have been recognised in this study.

OBJECTIVE: To identify, synthesise and evaluate studies that investigated the reliability of the Test of Gross Motor Development (TGMD) variants. METHODS: A systematic search was employed to identify studies that have investigated internal consistency, inter-rater, intra-rater and test-retest reliability of the TGMD variants through Scopus, Pubmed/MEDLINE, PsycINFO, Sport Discus and Web of Science databases. RESULTS: Of the 265 studies identified, 23 were included. Internal consistency, evaluated in 14 studies, confirming good-to-excellent consistency for the overall score and general motor quotient (GMQ), and acceptable-to-excellent levels in both subscales (locomotor and ball skills). Inter-rater reliability, evaluated in 19 studies, showing good-to-excellent intra-class correlation coefficient (ICC) values in locomotor skills score, ball skills score, overall score, and GMQ. Intra-rater reliability, evaluated in 13 studies, displaying excellent ICC values in overall score and GMQ, and good-to-excellent ICC values in locomotor skills score and ball skills score. Test-retest reliability was evaluated in 15 studies with 100% of the statistics reported above the threshold of acceptable reliability when ICC was not used. Studies with ICC statistic showed good-to-excellent values in ball skills score, overall score, and GMQ; and moderate-to-excellent values in locomotor skills score. CONCLUSIONS: Overall, the results of this systematic review indicate that, regardless of the variant of the test, the TMGD has moderate-to-excellent internal consistency, good-to-excellent inter-rater reliability, good-to-excellent intra-rater reliability, and moderate-to-excellent test-retest reliability. Considering the few high-quality studies in terms of internal consistency, it would be recommend to carry out further studies in this field to improve their quality. Since there is no gold standard for assessing FMS, TGMD variants could be appropriate when opting for a psychometrical robust test. However, standardized training protocols for coding TGMD variants seem to be necessary both for researchers and practitioners in order to ensure acceptable reliability.

University students, as a result of their lifestyles, represent a section of the population that is most likely to adopt sedentary behaviours. The aim of the present study was to analyse the determining factors dictating the performance of physical activity as well as sedentary behaviour among university students. A total of 608 students (64.6% women) from the University of Santiago de Compostela (Spain) were selected by stratified random sampling to take part in the study, which involved completing a questionnaire on lifestyle and physical activity. Of the participating students, 69.6% indicated that they performed physical activity; the main reasons given were to maintain fitness and for health, while a lack of time and laziness were the principal reasons given for abandoning or not taking up physical exercise. Significant associations were established between not doing physical activity and the time exposed to screens, time studying, feeling low and smoking; on the other hand, associations could be seen between doing physical activity and the participation of relatives (parents, mothers, partners, older siblings and friends) in physical activity, as well as a positive sense of satisfaction relating to physical education taught in schools. In conclusion, most of the university students did some physical activity, which was associated with less sedentary behaviour, while the influence of school physical education and of the habits of relatives played an important role.

AIM: To analyse the effect of oxygen fraction reduction (O2 14%, equivalent to 3250 m) on Q-CPR and rescuers' physiological demands. METHODOLOGY: A quasi-experimental study was carried out in a sample of 9 Q-CPR proficient health care professionals. Participants, in teams of 2 people, performed 10 min CPR on a Laerdal ResusciAnne mannequin (30:2 compression/ventilation ratio and alternating roles between rescuers every 2 min) in two simulated settings: T21-CPR at sea level (FiO2 of 21%) and T14 - CPR at 3250 m altitude (FiO2 of 14%). Effort self-perception was rated from 0 (no effort) to 10 (maximum demand) points. RESULTS: Quality of chest compressions was good and similar in both conditions (T21 vs T14). However, the percentage of ventilations with adequate tidal volume was lower in altitude than at sea level conditions (35.9 ± 25.2% vs. 54.7 ± 23.2%, p = 0.035). The subjective perception of effort was significantly higher at simulated altitude (5 ± 2) than at sea level (3 ± 2) (p = 0.038). Maximum heart rate during the tests was similar in both conditions; however, mean oxygen saturation was significantly lower in altitude conditions (90.5 ± 2.5% vs. 99.3 ± 0.5%, p < 0.001). CONCLUSION: Although performing CPR under simulated hypoxic altitude conditions significantly increases the physiological demands and subjective feeling of tiredness compared to sea level CPR, trained rescuers are able to deliver good Q-CPR in such conditions, at least in the first 10 min of resuscitation.
