Abstract
OBJECTIVES Current resuscitation guidelines recommend target chest compression depth (CCd) of approximately 4cm for infants and 5cm for children. Previous reports based on chest CT suggest these recommended CCd targets might be too deep for younger children. Our aim was to examine measurements of anterior-posterior chest diameter (APd) with a laser distance meter and calculate CCd targets in critically ill infants and children. DESIGN A retrospective descriptive study. SETTING Single-center PICU, using data from May 2019 to May 2022. PATIENTS All critically ill children admitted to PICU and under 8 years old were eligible to be included in the retrospective cohort. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The chest APd measurements using a laser distance meter are part of our usual practice on the PICU. Target CCd and the over-compression threshold CCd for each age group was calculated as 1/3 and 1/2 of APd, respectively. In 555 patients, the median (interquartile range) of the calculated target CCd for each age group was: 2.7 cm (2.5-2.9 cm), 2.9 cm (2.7-3.2 cm), 3.2 cm (3-3.5 cm), 3.4 cm (3.2-3.6 cm), 3.4 cm (3.2-3.6 cm), 3.6 cm (3.4-3.8 cm), 3.6 cm (3.4-4 cm), and 4 cm (3.5-4.2 cm), for 0, 2, 3-5, 6-8, 9-11, 12-17, 18-23, 24 to less than 60, and 60 to less than 96 months, respectively. Using guideline-recommended absolute CCd targets, 4 cm for infants and 5 cm for children, 49% of infants between 0 and 2 months, and 45.5% of children between 12 and 17 months would be over-compressed during cardiopulmonary resuscitation. CONCLUSIONS In our cohort, the 1/3 CCd targets calculated from APd measured by laser meter were shallower than the guideline-recommended CCd. Further studies including evaluating hemodynamics during cardiopulmonary resuscitation with these shallower CCd targets are needed.

Abstract
OBJECTIVES Current European guidelines for pediatric cardiopulmonary resuscitation (CPR) recommend the lower half of the sternum as the chest compression point (CP). In this study, we have used thoracic CT scans to evaluate recommended and optimal CP in relation to cardiac anatomy and structure. DESIGN Analysis of routinely acquired thoracic CT scans acquired from 2000 to 2020. SETTING Single-center pediatric department in a German University Hospital. PATIENTS Imaging data were obtained from 290 patients of 3-16 years old. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We measured and analyzed 14 thoracic metrics in each thoracic CT scan. In 44 of 290 (15.2%) scans, the recommended CP did not match the level of the cardiac ventricles. Anatomically, the optimal CP was one rib or one vertebral body lower than the recommended CP, that is, the optimal CP was more caudal to the level of the body of the sternum in 67 of 290 (23.1%) scans. The recommended compression depth appeared reasonable in children younger than 12 years old. At 12 years old or older, the maximum compression depth of 6 cm is less than or equal to one-third of the thoracic depth. CONCLUSIONS In this study of thoracic CT scans in children 3-16 years old, we have found that optimal CP for CPR appears to be more caudal than the recommended CP. Therefore, it seems reasonable to prefer to use the lower part of the sternum for CPR chest compressions. At 12 years old or older, a compression depth similar to that used in adults-6 cm limit-may be chosen.

Poor Concordance of One-Third Anterior-Posterior Chest Diameter Measurements With Absolute Age-Specific Chest Compression Depth Targets in Pediatric Cardiac Arrest Patients. J Am Heart Assoc 2023:e028418. [PMID: 37421276 PMCID: PMC10382104 DOI: 10.1161/jaha.122.028418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Accepted: 06/08/2023] [Indexed: 07/10/2023]
Abstract
Background Current pediatric cardiac arrest guidelines recommend depressing the chest by one-third anterior-posterior diameter (APD), which is presumed to equate to absolute age-specific chest compression depth targets (4 cm for infants and 5 cm for children). However, no clinical studies during pediatric cardiac arrest have validated this presumption. We aimed to study the concordance of measured one-third APD with absolute age-specific chest compression depth targets in a cohort of pediatric patients with cardiac arrest. Methods and Results This was a retrospective observational study from a multicenter, pediatric resuscitation quality collaborative (pediRES-Q [Pediatric Resuscitation Quality Collaborative]) from October 2015 to March 2022. In-hospital patients with cardiac arrest ≤12 years old with APD measurements recorded were included for analysis. One hundred eighty-two patients (118 infants >28 days old to <1 year old, and 64 children 1 to 12 years old) were analyzed. The mean one-third APD of infants was 3.2 cm (SD, 0.7 cm), which was significantly smaller than the 4 cm target depth (P<0.001). Seventeen percent of the infants had one-third APD measurements within the 4 cm ±10% target range. For children, the mean one-third APD was 4.3 cm (SD, 1.1 cm). Thirty-nine percent of children had one-third APD within the 5 cm ±10% range. Except for children 8 to 12 years old and overweight children, the measured mean one-third APD of the majority of the children was significantly smaller than the 5 cm depth target (P<0.05). Conclusions There was poor concordance between measured one-third APD and absolute age-specific chest compression depth targets, particularly for infants. Further study is needed to validate current pediatric chest compression depth targets and evaluate the optimal chest compression depth to improve cardiac arrest outcomes.

Should paediatric chest compression depth targets consider body habitus? - A chest computed tomography imaging study. Resusc Plus 2022; 9:100202. [PMID: 35118434 PMCID: PMC8792407 DOI: 10.1016/j.resplu.2022.100202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 12/14/2021] [Accepted: 01/03/2022] [Indexed: 01/03/2023] Open
Abstract
AIM This study explored how body habitus in the paediatric population might potentially affect the use of one-third external anterior-posterior (APD) diameter when compared to age-appropriate absolute chest compression depth targets. It also explored how body habitus could potentially affect the relationship between one-third external and internal APD (compressible space) and if body habitus indices were independent predictors of internal APD at the lower half of the sternum. METHODS This was a secondary analysis of a retrospective study of chest computed tomography (CT) scans of infants and children (>24-hours-of-life to less-than-18-years-old) from 2005 to 2017. Patients' scan images were reviewed for internal and external APDs at the mid-point of the lower half of the sternum. Body habitus and epidemiological data were extracted from the electronic medical records. RESULTS Chest CT scans of 193 infants and 398 children were evaluated. There was poor concordance between one-third external APD measurements and age-specific absolute chest compression depth targets, especially in infants and overweight/obese adolescents. There was a co-dependent relationship between one-third external APD and internal APD measurements. Overweight/obese children's and adolescents' internal and external APDs were significant different from the normal/underweight groups. Body-mass-index (BMI) of children and adolescents (p = 0.009), but not weight-for-length (WFL) of infants (p = 0.511), was an independent predictor of internal APD at the compression landmark. CONCLUSION This study demonstrated correlations between external and internal APDs which were affected by BMI but not WFL (infants). Clinical studies are needed to validate current chest compression guidelines especially for infants and overweight/obese adolescents.(250 words).

Abstract
We present the 2021 Singapore Paediatric Resuscitation Guidelines. The International Liaison Committee on Resuscitation's Pediatric Taskforce Consensus Statements on Science and Treatment Recommendations, which was published in October 2020, and the updated resuscitation guidelines from the American Heart Association and European Resuscitation Council, were reviewed and discussed by the committee. These recommendations were derived after deliberation of peer-reviewed evidence updates on paediatric resuscitation and took into consideration the local setting and clinical practice.
