A systematic review of interventions for resuscitation following drowning.

Objectives: The International Liaison Committee on Resuscitation, in collaboration with drowning researchers from around the world, aimed to review the evidence addressing seven key resuscitation interventions: 1) immediate versus delayed resuscitation; (2) compression first versus ventilation first strategy; (3) compression-only CPR versus standard CPR (compressions and ventilations); (4) ventilation with and without equipment; (5) oxygen administration prior to hospital arrival; (6) automated external defibrillation first versus cardiopulmonary resuscitation first strategy; (7) public access defibrillation programmes. Methods: The review included studies relating to adults and children who had sustained a cardiac arrest following drowning with control groups and reported patient outcomes. Searches were run from database inception through to April 2023. The following databases were searched Ovid MEDLINE, Pre-Medline, Embase, Cochrane Central Register of Controlled Trials. Risk of bias was assessed using the ROBINS-I tool and the certainty of evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation. The findings are reported as a narrative synthesis. Results: Three studies were included for two of the seven interventions (2,451 patients). No randomised controlled trials were identified. A retrospective observational study reported in-water resuscitation with rescue breaths improved patient outcomes compared to delayed resuscitation on land (n = 46 patients, very low certainty of evidence). The two observational studies (n = 2,405 patients), comparing compression-only with standard resuscitation, reported no difference for most outcomes. A statistically higher rate of survival to hospital discharge was reported for the standard resuscitation group in one of these studies (29.7% versus 18.1%, adjusted odds ratio 1.54 (95% confidence interval 1.01-2.36) (very low certainty of evidence). Conclusion: The key finding of this systematic review is the paucity of evidence, with control groups, to inform treatment guidelines for resuscitation in drowning.

Would anti-choking devices be correctly and quickly managed by health science students? A manikin crossover trial.

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.

An effort to reduce chest compression pauses during automated external defibrillator use among laypeople: A randomized partially blinded controlled trial.

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.

Near-peer mentoring and virtual reality for adult basic life support education in high school students.

Bystander cardiopulmonary resuscitation (CPR) can improve cardiac arrest survival; however, lack of willingness or community training lead to low bystander CPR rates. Virtual Reality (VR) Cardiopulmonary Resuscitation (CPR) training among high-school students is an innovative method to train bystander CPR skills. VR is well received by "technology natives" inherent among high school students and induces a greater sense of presence and agency compared to office-based CPR training. We describe a pilot trial with high school students using a near-peer mentoring framework using a single- player VR CPR training software (CBS, TetraSignum, Seoul, KR) in which both students collaboratively coach each other while performing in-VR CPR. Our pilot program recruited 3 pairs (n = 6) high school students during a local summer camp. During each 1.5-hour session, each pair learned about CPR and basic life support through a VR avatar either in-VR or displayed on a TV screen. The in-VR student practiced on the manikin while the other student could take notes on paper. Then each student was assessed on their CPR skills in-VR on a cardiac arrest avatar superimposed onto a real QCPR manikin, coached by the other student who could visualize CPR quality projected on the TV screen. The students then switched roles and debriefed about their experience. Overall, the students universally performed well and appreciated the collaborative nature of the learning experience. Further study is needed to explore barriers and enablers to implementation of VR CPR training at the high school level.

The Developmental Trajectory of Motor Competence of Children That Lived the COVID-19 Confinement Period: A Four-Year Follow-Up Study in Portuguese Children.

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.

Does Vibration Foam Roller Influence Performance and Recovery? A Systematic Review and Meta-analysis.

BACKGROUND: Foam rolling has been extensively investigated, showing benefits in performance and recovery. Recently, vibration has been added to foam rollers, with hypothesized advantages over conventional foam rollers. However, there is no systematic evidence in this regard. OBJECTIVE: To carry out a systematic review and meta-analysis about the effects of vibration foam roller (VFR) on performance and recovery. METHODS: A systematic search was conducted in PubMed/MEDLINE, Web of Science and SportDiscus according to the PRISMA guidelines. The outcomes included performance (jump, agility and strength) and recovery variables (blood flow, pain and fatigue) measured after an intervention with VFR. The methodological quality was assessed with the PEDro scale. A random-effects model was used to perform the meta-analysis. RESULTS: Initially, 556 studies were found and after the eligibility criteria 10 studies were included in the systematic review and 9 in the meta-analysis. There was no significant effects on jump performance (SMD = 0.14 [95% CI - 0.022 to 0.307]; p = 0.101; I2 = 1.08%) and no significant beneficial effects were reported on isokinetic strength (SMD = 0.16 [95% CI - 0.041 to 0.367]; p = 0.117; I2 = 9.7%). Recovery appears to be enhanced after VFR interventions, but agility does not seem to increase after VFR interventions. CONCLUSION: This systematic review and meta-analysis suggest that VFR could have great potential for increasing jump performance, agility, strength and enhancing recovery. Further research is needed to confirm the effects of VFR on performance and recovery. Trial Registration This investigation was registered in PROSPERO with the code CRD42021238104.

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.

Aprendiendo a reanimar en la escuela. Estudio en escolares de 8-12 años / Learning to resuscitate at school. Study in 8-12 year-old schoolchildren

Objetivo: Valorar cuantitativamente la capacidad de aprendizaje en soporte vital básico (teórica y práctica) de escolares de 8-12 años con un programa de formación adaptado a las escuelas. Material y métodos: Estudio cuasiexperimental con una muestra de conveniencia de 567 alumnos de 3° y 5° de Educación Primaria y 1° de Educación Secundaria Obligatoria, de 3 colegios concertados de Galicia, que recibieron 2h (una teórica y otra práctica) de formación en soporte vital básico por parte de sus profesores de Educación Física integrada en el programa escolar. Los niños fueron evaluados mediante un test teórico y una prueba práctica que midió la calidad de las compresiones torácicas y valoró la secuencia de soporte vital básico. (AU)

Material and methods: Quasi-experimental study with a convenience sample of 567 pupils in 3rd, 5th and 1st year of Primary Education, and Compulsory Secondary Education, respectively, from 3 public schools in Galicia. They received 2h (one theoretical and another practical) of basic life support training by their Physical Education teachers, as part of the school program. The children were evaluated by a theoretical test and a practical skill test that measured the quality of chest compressions, and assessed the performance of the basic life support sequence. (AU)

Learning to resuscitate at school. Study in 8-12 year-old schoolchildren.

OBJECTIVE: To quantitatively assess the learning capacity of school children aged between 8-12 years in basic life support (theory and practice) after a feasible school training programme. MATERIAL AND METHODS: Quasi-experimental study with a convenience sample of 567 pupils in 3rd and 5th year of Primary Education, and first year of Compulsory Secondary Education, from 3 public schools in Galicia. They received 2h (one theoretical and another practical) of basic life support training by their Physical Education teachers, as part of the school program. The children were evaluated by a theoretical test and a practical skill test that measured the quality of chest compressions, and assessed the performance of the basic life support sequence. RESULTS: The level of knowledge increased with respect to the baseline, and was higher in the higher grades (P < .001). The complete basic life support sequence was carried out by 16.5% of pupils in the 3rd year of Primary Education, 54.4% of pupils in the 5th year of Primary Education, and 28.5% of pupils in the 1st year of Secondary Education (P = .030). The following compression quality parameters improved significantly with age: continuity of compressions (P < .001), percentage of compressions performed at correct depth (P = .002), and median depth (P < .001), while the percentage of compressions with correct decompression decreased significantly (P < .001). CONCLUSIONS: Although their anthropometric characteristics may not allow them to achieve the ideal quality of this manoeuvre, a 2h theoretical and practical training programme, taught by Physical Education teachers, helps to improve the ability of children younger than 13 years old to recognise the emergency, start the chain of survival, and initiate chest compressions.

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.

Performing Simulated Basic Life Support without Seeing: Blind vs. Blindfolded People.

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.

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.

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.

Intra-Rater (Live vs. Video Assessment) and Inter-Rater (Expert vs. Novice) Reliability of the Test of Gross Motor Development-Third Edition.

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.
