Kao CL, Tsou JY, Hong MY, Chang CJ, Tu YF, Huang SP, Su FC, Chi CH. A novel CPR-assist device vs. established chest compression techniques in infant CPR: A manikin study. Am J Emerg Med 2024; 77:81-86. [PMID: 38118386 DOI: 10.1016/j.ajem.2023.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 11/20/2023] [Accepted: 12/04/2023] [Indexed: 12/22/2023] Open
Abstract
INTRODUCTION Guidelines for infant CPR recommend the two-thumb encircling hands technique (TTT) and the two-finger technique (TFT) for chest compression. Some devices have been designed to assist with infant CPR, but are often not readily available. Syringe plungers may serve as an alternative infant CPR assist device given their availability in most hospitals. In this study, we aimed to determine whether CPR using a syringe plunger could improve CPR quality measurements on the Resusci-Baby manikin compared with traditional methods of infant CPR. METHODS Compression area with a diameter of 1 to 2 cm is recommended in previous infant CPR device researches. In this is a randomized crossover manikin study, we examined the efficacy of the Syringe Plunger Technique (SPT) which uses the plunger of the 20 ml syringe with a 2 cm diameter flat piston, commonly available in hospital, for infant External Chest Compressions (ECC). Participants performed TTT, TFT and SPT ECC on Resusci® Baby QCPR® according to 2020 BLS guidelines. RESULTS Sixty healthcare providers participated in this project. The median (IQR) ECC depths in the TTT, TFT and SPT in the first minute were 41 mm (40-42), 40 mm (38-41) and 40 mm (39-41), respectively, with p < 0.001. The median (IQR) ECC recoil in the TTT, TFT and SPT groups in the first minute was 15% (1-93), 64% (18-96) and 53% (8-95), respectively, with p = 0.003. The result in the second minute had similar findings. The SPT had the best QCPR score and less fatigue. CONCLUSION The performance of chest compression depth and re-rebound ratio was statistically different among the three groups. TTT has good ECC depth and depth accuracy but poor recoil. TFT is the complete opposite. SPT can achieve a depth close to TTT and has a good recoil performance as TFT. Regarding comprehensive performance, SPT obtains the highest QCPR score, and SPT is also less fatigued. SPT may be an effective alternative technique for infant CPR.

Abstract
AIM The International Liaison Committee on Resuscitation Neonatal Life Support Task Force undertook a scoping review of the literature to identify evidence relating to neonatal cardiopulmonary resuscitation. METHODS MEDLINE complete, EMBASE and Cochrane database of Systematic reviews were searched from inception to November 2021. Two authors screened titles and abstracts and full text reviewed. Studies were eligible for inclusion if they were peer-reviewed and assessed one of five aspects of chest compression in the newborn infant including: (1) heart rate thresholds to start chest compressions (CC), (2) compression to ventilation ratio (C:V ratio), (3) CC technique, (4) oxygen use during CC and 5) feedback devices to optimise CC. RESULTS Seventy-four studies were included (n=46 simulation, n=24 animal and n=4 clinical studies); 22/74 were related to compression to ventilation ratios, 29/74 examined optimal technique to perform CC, 7/74 examined oxygen delivery and 15/74 described feedback devices during neonatal CC. CONCLUSION There were very few clinical studies and mostly manikin and animal studies. The findings either reinforced or were insufficient to change previous recommendations which included to start CC if heart rate remains <60/min despite adequate ventilation, using a 3:1 C:V ratio, the two-thumb encircling technique and 100% oxygen during CC.

Abstract
Background: The Neonatal Life Support Consensus on Science With Treatment Recommendations states that chest compressions (CC) be performed preferably with the 2-thumb encircling technique. The aim of this study was to compare the hemodynamic effects of four different finger positions during CC in a piglet model of neonatal asphyxia. Methods: Seven asphyxiated post-transitional piglets were randomized to CC with 2-thumb-, 2-finger-, knocking-fingers-, and over-the-head 2-thumb-techniques for one minute at each technique. CC superimposed with sustained inflations were performed manually. Results: Seven newborn piglets (age 0-4 days, weight 2.0-2.1 kg) were included in the study. The mean (SD) slope rise of carotid blood flow was significantly higher with the 2-thumb-technique and over-the-head 2-thumb-technique (118 (45) mL/min/s and 121 (46) mL/min/s, respectively) compared to the 2-finger-technique and knocking-finger-technique (75 (48) mL/min/s and 71 (67) mL/min/s, respectively) (p < 0.001). The mean (SD) dp/dtmin (as an expression of left ventricular function) was significantly lower with the 2-thumb-technique, with -1052 (369) mmHg/s, compared to -568 (229) mmHg/s and -578(180) mmHg/s (both p = 0.012) with the 2-finger-technique and knocking-finger-technique, respectively. Conclusion: The 2-thumb-technique and the over-the-head 2-thumb-technique resulted in improved slope rises of carotid blood flow and dp/dtmin during chest compression.

Abstract
BACKGROUND Paediatric out-of-hospital cardiac arrest (OHCA) is the reason for an emergency call in approximately 8/100,000 person-years. Improvement of OHCA resuscitation needs a quality chain of survival and a rapid start of resuscitation. The aim of this study was to compare the efficacy of two resuscitation techniques provided on a mannequin, the two-fingers technique (TFT) and the two-thumbs encircling hand technique (TTHT), explained by a trained emergency call responder on the phone in a population of non-health professionals. METHODS We conducted a randomised crossover study in the simulation lab of a University Hospital. The participants included in the study were non-health professional volunteers of legal age. The participants were assigned (1:1 ratio) to two groups: group A: TFT then TTHT, group B: TTHT then TFT. Scenario and techniques were discovered during the evaluation. RESULTS Thirty-five volunteers were randomised before the sessions and 33 ultimately came to the simulation lab. We found a better median QCPR global score during TTHT sessions than during TFT sessions (74 vs. 59, P = 0.046). Linear mixed models showed that the TTHT method was the only variable associated with a better QCPR global score [model 1: β = 14.3; 95% confidence interval (CI), 2.4-26.2; model 2: β = 14.5; 95% CI, 2.5-26.6]. CONCLUSION Our study showed the superiority of TTHT for infant CPR performed by non-health professionals when an emergency call responder advised them over the phone. It seemed to be the best technique for a solo rescuer regardless of previous training.

Abstract
Prolonged resuscitation in neonates, although quite rare, may occur in response to profound intractable bradycardia as a result of asphyxia. In these instances, chest compressions and medications may be necessary to facilitate return of spontaneous circulation. While performing chest compressions, the two thumb method is preferred over the two finger technique, although several newer approaches are under investigation. While the ideal compression to ventilation ratio is still uncertain, a 3:1 ratio remains the recommendation by the Neonatal Resuscitation Program. Use of feedback mechanisms to optimize neonatal cardiopulmonary resuscitation (CPR) show promise and are currently under investigation. While performing optimal cardiac compressions to pump blood, use of medications to restore spontaneous circulation will likely be necessary. Current recommendations are that epinephrine, an endogenous catecholamine be used preferably intravenously or by intraosseous route, with the dose repeated every 3-5 minutes until return of spontaneous circulation. Finally, while the need for volume replacement is rare, it may be considered in instances of acute blood loss or poor response to resuscitation.

Abstract
BACKGROUND Current cardiopulmonary resuscitation (CPR) guidelines recommend the two-finger technique (TFT) of chest compression (CC) in infants for a single rescuer. We hypothesized that healthcare providers cannot achieve adequate CC depth with TFT, even if using real-time visual feedback (RVF). METHODS This was a cross-over study, randomizing participants to perform three sets of 2-min continuous CC, comparing (i) TFT with RVF, (ii) the one-hand technique (OHT) without RVF, and (iii) OHT with RVF. A standard CPR trainer manikin of a 3-month-old infant and a monitor/defibrillator that displays and records the quantitative CC quality were used. We set a target compression depth of 40-50 mm and a target compression rate of 100-120/min. Data were analyzed using the Friedman test and Bonferroni correction. Statistical significance was defined as P-value of< 0.05. RESULTS Fifty-nine healthcare providers participated in the study. The mean compression depth was 24 mm (interquartile range [IQR], 22-26 mm) in TFT with RVF and 43 mm (IQR, 38-48 mm) in OHT without RVF, P < 0.001. The proportion of adequate CC depth was 0% (IQR, 0-0%) in TFT with RVF, 22% (IQR, 5-54%) in OHT without RVF, and 62% (IQR, 29-83%) in OHT with RVF. The mean compression rate was within the target range in all three techniques. CONCLUSIONS The TFT cannot produce the CC depth that meets the recommendation of the current CPR guidelines for an infant with RVF, whereas the OHT does.

Methods and Results In a randomized crossover design, 78 medical students performed 2 minutes of cardiopulmonary resuscitation with mouth‐to‐nose ventilation at a 30:2 rate on a Resusci Baby QCPR infant manikin (Laerdal, Stavanger, Norway), using a barrier device and the 2‐finger and 2‐thumb compression techniques. Frequency and depth of chest compressions, proper hand position, complete chest recoil at each compression, hands‐off time, tidal volume, and number of ventilations were evaluated through manikin‐embedded SkillReporting software. After the interventions, standard Likert questionnaires and analog scales for pain and fatigue were applied. The variables were compared by a paired t‐test or Wilcoxon test as suitable. Seventy‐eight students participated in the study and performed 156 complete interventions. The 2‐thumb technique resulted in a greater depth of chest compressions (42 versus 39.7 mm; P<0.01), and a higher percentage of chest compressions with adequate depth (89.5% versus 77%; P<0.01). There were no differences in ventilatory parameters or hands‐off time between techniques. Pain and fatigue scores were higher for the 2‐finger technique (5.2 versus 1.8 and 3.8 versus 2.6, respectively; P<0.01). Conclusions In a simulation of out‐of‐hospital, single‐rescuer infant cardiopulmonary resuscitation, the 2‐thumb technique achieves better quality of chest compressions without interfering with ventilation and causes less rescuer pain and fatigue.

Abstract
Aims The aim of this randomised study was to compare the two-finger technique (TFT) performance using dominant hand (DH) and non-dominant hand (NH) during simulated infant CPR (iCPR). Methods 24 participants performed 3-min iCPR using TFT with DH or NH followed by 3-min iCPR with their other hand. Perceived fatigue was rated using visual analogue scale. Primary outcomes - (i) difference between DH and NH for compression depth (CCD), compression rate (CCR), residual leaning (RL) and duty cycle (DC); (ii) difference between first and last 30 s of iCPR performance with DH and NH. Secondary outcomes - (i) perception of fatigue between DH and NH; (ii) relationship between perception of fatigue and iCPR performance. Results No significant difference between DH and NH for any iCPR metric. CCR (DH: P = 0.02; NH: P = 0.004) and DC (DH: P = 0.04; NH: P < 0.001) were significantly different for the last 30 s for DH and NH. Perception of fatigue for NH (76.8 ± 13.4 mm) was significantly higher (t = -3.7, P < 0.001) compared to DH (62.8 ± 12.5 mm). No significant correlation between iCPR metrics and perception of fatigue for DH. However, a significant correlation was found for CCR (r = 0.43; P = 0.04) and RL (r = -0.48; P = 0.02) for NH. Conclusion No difference in performance of iCPR with DH versus NH was determined. However, perception of fatigue is higher in NH and was related to CCR and RL, with no effect on quality of performance. Based on our results, individuals performing iCPR can offer similar quality of infant chest compressions regardless of the hand used or the perception of fatigue, under the conditions explored in this study.

Two-Thumb or Two-Finger Technique in Infant Cardiopulmonary Resuscitation by a Single Rescuer? A Meta-Analysis with GOSH Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17145214. [PMID: 32707697 PMCID: PMC7400494 DOI: 10.3390/ijerph17145214] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 07/10/2020] [Accepted: 07/15/2020] [Indexed: 01/08/2023]
Abstract
Out-of-hospital infant cardiopulmonary arrest is a fatal and uncommon event. High mortality rates and poor neurological outcomes may be improved by early cardiopulmonary resuscitation (CPR). The ongoing debate over two different infant CPR techniques, the two-thumb (TT) and the two-finger (TF) technique, has remained, especially in terms of the adequate compression depth, compression rate, and hands-off time. In this article, we searched three major databases, PubMed, EMBASE (Excerpta Medica database), and CENTRAL (Cochrane Central Register of Controlled Trials), for randomized control trials which compared the outcomes of interest between the TT and TF techniques in infant CPR. The results showed that the TT technique was associated with higher proportion of adequate compression depth (Mean difference (MD): 19.99%; 95%, Confidence interval (CI): 9.77 to 30.22; p < 0.01) than the TF technique. There was no significant difference in compression rate and hands-off time. In our conclusion, the TT technique is better in terms of adequate compression depth than the TF technique, without significant differences in compression rate and hands-off time.

Analysis of Chest-Compression Depth and Full Recoil in Two Infant Chest-Compression Techniques Performed by a Single Rescuer: Systematic Review and Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17114018. [PMID: 32516929 PMCID: PMC7312068 DOI: 10.3390/ijerph17114018] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 05/31/2020] [Accepted: 06/03/2020] [Indexed: 12/27/2022]
Abstract
Pediatric cardiac arrest is associated with high mortality and permanent neurological injury. We aimed to compare the effects of the two-thumb (TT) and two-finger (TF) techniques in infant cardiopulmonary resuscitation (CPR) performed by a single rescuer. We searched PubMed, EMBASE, and CENTRAL for randomized control trials published before December 2019. Studies comparing the TT and TF techniques in infant CPR were included for meta-analysis. Relevant information was extracted for methodological assessment. Twelve studies were included. The TT technique was associated with deeper chest-compression depth (mean difference: 4.71 mm; 95% confidence interval: 3.61 to 5.81; p < 0.001) compared with the TF technique. The TF technique was better in terms of the proportion of complete chest recoil (mean difference: -11.73%; 95% confidence interval: -20.29 to -3.17; p = 0.007). CPR was performed on a manikin model, and the application of the results to real human beings may be limited. The TT technique was superior to the TF technique in terms of chest-compression depth, but with inferior chest full recoil. Future investigations should focus on modifying the conventional TT technique to generate greater compression depth and achieve complete chest recoil.

Abstract
OBJECTIVES In effort to improve chest compression quality among health care providers, numerous feedback devices have been developed. Few studies, however, have focused on the use of cardiopulmonary resuscitation feedback devices for infants and children. This study evaluated the quality of chest compressions with standard team-leader coaching, a metronome (MetroTimer by ONYX Apps), and visual feedback (SkillGuide Cardiopulmonary Feedback Device) during simulated infant cardiopulmonary resuscitation. METHODS Seventy voluntary health care providers who had recently completed Pediatric Advanced Life Support or Basic Life Support courses were randomized to perform simulated infant cardiopulmonary resuscitation into 1 of 3 groups: team-leader coaching alone (control), coaching plus metronome, or coaching plus SkillGuide for 2 minutes continuously. Rate, depth, and frequency of complete recoil during cardiopulmonary resuscitation were recorded by the Laerdal SimPad device for each participant. American Heart Association-approved compression techniques were randomized to either 2-finger or encircling thumbs. RESULTS The metronome was associated with more ideal compression rate than visual feedback or coaching alone (104/min vs 112/min and 113/min; P = 0.003, 0.019). Visual feedback was associated with more ideal depth than auditory (41 mm vs 38.9; P = 0.03). There were no significant differences in complete recoil between groups. Secondary outcomes of compression technique revealed a difference of 1 mm. Subgroup analysis of male versus female showed no difference in mean number of compressions (221.76 vs 219.79; P = 0.72), mean compression depth (40.47 vs 39.25; P = 0.09), or rate of complete release (70.27% vs 64.96%; P = 0.54). CONCLUSIONS In the adult literature, feedback devices often show an increase in quality of chest compressions. Although more studies are needed, this study did not demonstrate a clinically significant improvement in chest compressions with the addition of a metronome or visual feedback device, no clinically significant difference in Pediatric Advanced Life Support-approved compression technique, and no difference between compression quality between genders.

Abstract
Background: Rescuer fatigue during neonatal CPR can affect CPR quality leading to reduced cerebral and myocardial perfusion. Aim: To investigate rescuer fatigue during simulated neonatal CPR using both objective (heart rate and cardiac output) and subjective measures. Methods: A randomized crossover manikin study performed. Nineteen doctors working in neonatology were randomized to (a) two-thumb term, (b) two-finger term, (c) two-thumb preterm, or (d) two-finger preterm group. Cardiac output and heart rate were measured with a non-invasive cardiac output monitor. A Likert scale assessed participants' level of perceived exertion. Results: In the preterm group, the mean change in HR from rest to 5 min in the TT group was 11.58 bpm (SD 6.22) vs. 9.94 bpm (SD 8.48), (p-value 0.36). There was no difference in change in CO, 2.10 (SD 1.15) in the TT group vs. 1.39 (SD 1.63) in TF group (p value 0.23). There was no difference in BORG RPE rating. In the term group, the mean change in HR from rest to 5 min was 15 bpm (SD 8.40) in TT group and 13 bpm (SD 7.86) in TF group, (p-value 0.416). The median change in CO from rest to 5 min was 1.50 (0.78 to 2.42 IQR) in TT group vs. 1.60 (0.65 to 3.0 IQR) in TF group. Conclusion: Providing chest compressions is associated with an increase in both heart rate and cardiac output. We did not identify difference between objective and subjective measures of fatigue between either technique in a preterm or term model.

Abstract
BACKGROUND The recommended chest compression technique for a single rescuer performing infant cardiopulmonary resuscitation is the two-finger technique. For 2 rescuers, a two-thumb-encircling hands technique is recommended. Several recent studies have reported that the two-thumb-encircling hands technique is more effective for high-quality chest compression than the two-finger technique for a single rescuer performing infant cardiopulmonary resuscitation. We undertook a systematic review and meta-analysis of infant manikin studies to compare two-thumb-encircling hands technique with two-finger technique for a single rescuer. METHODS We searched MEDLINE, EMBASE, and the Cochrane Library for eligible randomized controlled trials published prior to December 2017, including cross-over design studies. The primary outcome was the mean difference in chest compression depth (mm). The secondary outcome was the mean difference in chest compression rate (counts/min). A meta-analysis was performed using Review Manager (version 5.3. Copenhagen: The Nordic Cochrane Centre, The Cochrane Collaboration, 2014). RESULTS Six studies that had reported data concerning both chest compression depth and chest compression rate were included. The two-thumb-encircling hands technique was associated with deeper chest compressions compared with two-finger technique for mean chest compression depth (mean difference, 5.50 mm; 95% confidence interval, 0.32-10.69 mm; P = .04), but no significant difference in the mean chest compression rate (mean difference, 7.89 counts/min; 95% confidence interval, to 0.99, 16.77 counts/min; P = .08) was noted. CONCLUSION This study indicates that the two-thumb-encircling hands technique is a more appropriate technique for a single rescuer to perform high-quality chest compression in consideration of chest compression depth than the two-finger technique in infant manikin studies.

Abstract
We designed the newly developed flexed two-finger chest compression technique for cardiopulmonary resuscitation (CPR) in infants to increase the quality of chest compression by considering the advantages and disadvantages of the two-thumb encircling hand technique and conventional two-finger technique. The aim of the study is to compare the performance of the flexed two-finger technique and the currently used two-thumb technique or two-finger technique for infant CPR. A total of 42 doctors conducted 2-min single-rescuer CPR on a cardiac arrest infant model using the two-thumb technique followed, in a random order, by the two-finger technique and the flexed two-finger technique. Although the ratio of the adequate compression depth was highest in the two-thumb technique, followed by the flexed two-finger technique and two-finger technique (100% [98-100] vs. 99% [80-100] vs. 76% [42-95], respectively, P < 0.001), the hand-off time of the two-thumb technique was significantly longer than in the two-finger technique and flexed two-finger technique (31 s [28-35] vs. 29 s [27-32] vs. 29 s [26-32], respectively, P < 0.001). The number of total chest compressions of the two-thumb technique was significantly lower than in the two-finger technique and flexed two-finger technique (150 [148-159] vs. 159 [149-173] vs. 162 [150-172], respectively, P < 0.001). The newly developed chest compression technique could provide adequate compression depth without increasing the hand-off time during single-rescuer infant CPR.Trial registration: Clinical Research Information Service, KCT0002730.

Abstract
BACKGROUND Approximately 90% of pediatric emergency care is provided in community emergency departments (CEDs) that care for both adults and children. Paradoxically, the majority of pediatric emergency medicine knowledge generation, quality improvement work, and clinical training occurs in children's hospitals. There is a paucity of information of perceptions on pediatric care from CED providers. This information is needed to guide the development of strategies to improve CED pediatric readiness. OBJECTIVE The objective was to explore interprofessional CED providers' perceptions of caring for pediatric patients. METHODS A preparticipation survey collected data on demographics, experience, and comfort in caring for children. Emergency pediatric simulations were then utilized to prime interprofessional teams for debriefings. These discussions underwent qualitative analysis by three blinded authors who coded transcripts into themes through an inductive method derived from grounded theory. The other authors participated in confirmability and dependability checks. RESULTS A total of 171 community hospital providers from six CEDs completed surveys (49% nurses, 22% physicians, 23% technicians). The majority were PALS trained (70%) and experienced fewer than five pediatric resuscitations in their careers (61%). Most self-reported comfort in caring for acutely ill and injured children. From the debriefings, three major challenge themes emerged: 1) knowledge and skill limitations attributed to infrequency of training and actual clinical events, 2) the emotional toll of caring for a sick child, and 3) acknowledgment of pediatric specific quality and safety deficits. Subthemes focused on causes and potential mitigating factors contributing to these challenges. A solution theme highlighted novel partnering opportunities with local children's hospitals. CONCLUSION Interprofessional CED providers perceive that caring for pediatric patients is challenging due to case infrequency, the emotional toll of caring for sick children, and pediatric quality and safety deficits in their systems. These areas of focus can be used to generate specific strategies for improving CED pediatric readiness.

Abstract
BACKGROUND In newborns, ventilation is a key resuscitation element but optimal chest compression (CC) improves resuscitation quality. The study compared two infant CC techniques during simulated newborn resuscitation performed by nurses. METHODS The randomized crossover manikin, multicenter trial involved 52 nurses. They underwent training with two CC techniques: standard two-finger technique (TFT) and novel two-thumb technique (NTTT; two thumbs at 90° to the chest, fingers in a fist). One week later, the participants performed resuscitation with the two techniques. A Tory® S2210 Tetherless and Wireless Full-term Neonatal Simulator was applied, with a 3:1 compression to ventilation ratio. CC quality in accordance with the 2015 American Heart Association guidelines was assessed during the 2-min resuscitation. RESULTS Median CC depth was 30 mm for TFT and 37 mm for NTTT (p = 0.002). Correct hand placement reached 98% in both techniques; full chest relaxation was obtained in 97% vs. 94% for TFT and NTTT, respectively. CC fraction was slightly better for NTTT (74% vs. 70% for TFT; p = 0.044), the ventilation volume was comparable for both techniques. On a 100-degree scale (1 - no fatigue; 100 - extreme fatigue), the participant tiredness achieved 72 points (IQR 61-77) for TFT vs. 47 points (IQR 40-63) for NTTT (p = 0.034). For real resuscitation, 86.5% would choose NTTT and 13.5% TFT. CONCLUSIONS The NTTT technique proved superior to TFT. Evidence suggests that NTTT offers better CC depth in various medical personnel groups. One-rescuer TFT quality is not consistent with resuscitation guidelines.

Abstract
Objective: To compare a novel two-thumb chest compression technique with standard techniques during newborn resuscitation performed by novice physicians in terms of median depth of chest compressions, degree of full chest recoil, and effective compression efficacy. Patients and Methods: The total of 74 novice physicians with less than 1-year work experience participated in the study. They performed chest compressions using three techniques: (A) The new two-thumb technique (nTTT). The novel method of chest compressions in an infant consists in using two thumbs directed at the angle of 90° to the chest while closing the fingers of both hands in a fist. (B) TFT. With this method, the rescuer compresses the sternum with the tips of two fingers. (C) TTHT. Two thumbs are placed over the lower third of the sternum, with the fingers encircling the torso and supporting the back. Results: The median depth of chest compressions for nTTT was 3.8 (IQR, 3.7-3.9) cm, for TFT-2.1 (IQR, 1.7-2.5) cm, while for TTHT-3.6 (IQR, 3.5-3.8) cm. There was a significant difference between nTTT and TFT, and TTHT and TFT (p < 0.001) for each time interval during resuscitation. The degree of full chest recoil was 93% (IQR, 91-97) for nTTT, 99% (IQR, 96-100) for TFT, and 90% (IQR, 74-91) for TTHT. There was a statistically significant difference in the degree of complete chest relaxation between nTTT and TFT (p < 0.001), between nTTT and TTHT (p = 0.016), and between TFT and TTHT (p < 0.001). Conclusion: The median chest compression depth for nTTT and TTHT is significantly higher than that for TFT. The degree of full chest recoil was highest for TFT, then for nTTT and TTHT. The effective compression efficiency with nTTT was higher than for TTHT and TFT. Our novel newborn chest compression method in this manikin study provided adequate chest compression depth and degree of full chest recoil, as well as very good effective compression efficiency. Further clinical studies are necessary to confirm these initial results.

Abstract
AIM To use video review to compare CC quality between 2-thumb encircling (2T) and one-hand anterior (1H) hand position in infants receiving CPR. METHODS Events where an infant received >2min of CC using a CPR monitor device while videorecorded were included. CC were measured in segments provided by a single compressor; segment duration, identity of the compressor, and hand position (2T vs 1H) was determined from video review. CC rate and depth were measured by the monitor device. RESULTS Seven infants received 111min of CCs from a total of 28 providers. 12/28 providers were assessed using both 2T and 1H; 6 providers used 2T and 1H in the same patient. 80 CC segments were analyzed; the median duration of CC segments was 74s (IQR 50-95s). Median CC rate across all segments was 127/min (IQR 115-142/min); median CC depth was 3.0cm (IQR 2.4-3.4cm). 2T position was used in 33/80 (41%) of segments. There was no significant difference in CC depth between 2T and 1H position (3.0±0.8 vs 3.0±0.6cm, p=0.81). 1H position was significantly associated with faster CC rate than 2T position (134±18 vs. 118±15 CC/min, p<0.001). CONCLUSIONS During CC in infants, 1H position was associated with a greater prevalence of inappropriately fast CC rate compared to 2T. There was no significant difference in depth between 2T and 1H. Future studies should evaluate the effect of hand position on clinical outcomes.

Abstract
OBJECTIVE Out-of-hospital cardiac arrest (OHCA) in pediatrics is a devastating event associated with poor survival rates. Although telephone dispatcher-assisted cardiopulmonary resuscitation (CPR; T-CPR) instructions improve the frequency and quality of bystander CPR for OHCA in adults, this support remains undeveloped in children. Our objective was to assess the effectiveness of a pediatric T-CPR protocol in untrained and trained bystanders. Secondarily, we sought to determine the feasibility and the effectiveness of ventilation in such a protocol. METHODS Eligible adults with no CPR experience were recruited in a movie theater in Liege, as well as bachelor nursing students in Liege. All volunteers were randomly assigned either to T-CPR or to no-T-CPR using randomization. The volunteers were exposed to a pediatric manikin model cardiac arrest. On the basis of Cardiff evaluation test, data were collected to evaluate CPR performance. RESULTS A total of 115 volunteers were assigned to 4 groups: untrained nonguided group (n = 27), untrained guided group (n = 32), trained nonguided group (n = 26), and trained guided group (n = 30). We found an improvement in CPR performance in the guided groups. Most volunteers (81.2%) in untrained guided group and 83.3% in the trained guided group were able to give 2 ventilations after each compressions cycle. CONCLUSIONS In a pediatric manikin model of OHCA, T-CPR instructions including mouth-to-mouth ventilations and chest compressions produced a significant increase in resuscitation performance not only among previously untrained but also among trained volunteers.

Abstract
AIM The quality of chest compression (CC) delivered during neonatal and infant cardiopulmonary resuscitation (CPR) is identified as the most important factor to achieve the increase of survival rate without major neurological deficit to the patients. The objective of the study was to systematically review all the available studies that have compared the two different techniques of hand placement on infants and neonatal resuscitation, from 2010 to 2015 and to highlight which method is more effective. METHODS A review of the literature using a variety of medical databases, including Cochrane, MEDLINE, and SCOPUS electronic databases. The following MeSH terms were used in the search: infant, neonatal, CPR, CC, two-thumb (TT) technique/method, two-finger (TF) technique/method, rescuer fatigue, thumb/finger position/placement, as well as combinations of these. RESULTS Ten studies met the inclusion criteria; nine observational studies and a randomized controlled trial. All providers performed either continuous TF or TT technique CCs and the majority of CPR performance was taken place in infant trainer manikin. CONCLUSIONS The majority of the studies suggest the TT method as the more useful for infants and neonatal resuscitation than the TF.

Abstract
BACKGROUND The impact of high-quality chest compressions during CPR for the patients' outcome is undisputed, as it is essential for maintaining vital organ perfusion. The aim of our study is to compare the quality of chest compression (CC) and ventilation among the two current standard techniques with our novel "nTTT" technique in infant CPR. METHODS In this randomized crossover, manikin trial, participants performed CCs using three techniques in a randomized sequence: standard two finger technique (TFT); standard two thumb technique (TTHT), and the 'new two-thumb technique' (nTTT). The novel method of CCs in an infant consists in using two thumbs directed at the angle of 90° to the chest while closing the fingers of both hands in a fist. RESULTS Median depth compression using the distinct chest compression techniques varied and amounted to 26 [IQR, 25-28] mm for TFT, and 39 [IQR, 39-39] mm for TTHT as well as for nTTT. Best percentage of fully released compressions were received using TFT (100[100-100] %), then in the case of nTTT (99[98-100] %), and the worst in situation where TTHT (18[14-19] %). was used. The fastest chest compression rate was achieved with TFT (134[IQR, 129-135]/min) and the slowest when using nTTT (109 [IQR, 105-111]/min). CONCLUSIONS We found that our new nTTT technique's performance, in terms of compression depth, hands-off time, and ventilation quality, is comparable to the current standards. Based on our findings of this initial manikin study, the nTTT technique is superior to TFT in many of parameters that are vital to a quality chest compression during pediatric CPR.

Abstract
This study compared the effectiveness two-finger chest compression technique (TFCC) performed using the right vs. left hand and the index-middle vs. middle-ring fingers. Four different finger/hand combinations were tested randomly in 30 healthcare providers performing TFCC (Test 1: the right index-middle fingers; Test 2: the left index-middle fingers; Test 3: the right middle-ring fingers; Test 4: the left middle-ring fingers) using two cross-over trials. The "patient" was a 3-month-old-infant-sized manikin. Each experiment consisted of cardiopulmonary resuscitation (CPR) consisting of 2 minutes of 30:2 compression: ventilation performed by one rescuer on a manikin lying on the floor as if in cardiac arrest. Ventilations were performed using the mouth-to-mouth method. Compression and ventilation data were collected during the tests. The mean compression depth (MCD) was significantly greater in TFCC performed with the index-middle fingers than with the middle-ring fingers regardless of the hand (95% confidence intervals; right hand: 37.8-40.2 vs. 35.2-38.6 mm, P = 0.002; left hand: 36.9-39.2 vs. 35.5-38.1 mm, P = 0.003). A deeper MCD was achieved with the index-middle fingers of the right versus the left hand (P = 0.004). The ratio of sufficiently deep compressions showed the same patterns. There were no significant differences in the other data. The best performance of TFCC in simulated 30:2 compression: ventilation CPR performed by one rescuer on an infant in cardiac arrest lying on the floor was obtained using the index-middle fingers of the right hand.
