Background: Alternative cardiopulmonary resuscitation (CPR) algorithms, introduced to improve outcomes after cardiac arrest, have so far not been compared in randomized trials with established CPR guidelines.
Methods: 286 physician teams were confronted with simulated cardiac arrests and randomly allocated to one of three versions of a CPR algorithm: (1) current International Liaison Committee on Resuscitation (ILCOR) guidelines ("ILCOR"), (2) the cardiocerebral resuscitation ("CCR") protocol (3 cycles of 200 uninterrupted chest compressions with no ventilation), or (3) a local interpretation of the current guidelines ("Arnsberg", immediate insertion of a supraglottic airway and cycles of 200 uninterrupted chest compressions). The primary endpoint was percentage of hands-on time.
Results: Median percentage of hands-on time was 88 (interquartile range (IQR) 6) in "ILCOR" teams, 90 (IQR 5) in "CCR" teams ( = 0.001 vs. "ILCOR"), and 89 (IQR 4) in "Arnsberg" teams ( = 0.032 vs. "ILCOR"; = 0.10 vs. "CCR"). "ILCOR" teams delivered fewer chest compressions and deviated more from allocated targets than "CCR" and "Arnsberg" teams. "CCR" teams demonstrated the least within-team and between-team variance.
Conclusions: Compared to current ILCOR guidelines, two alternative CPR algorithms advocating cycles of uninterrupted chest compressions resulted in very similar hands-on times, fewer deviations from targets, and less within-team and between-team variance in execution.

Spondylo-thoracic dysplasia (STD) is a set of rare congenital abnormalities involving the vertebrae and thorax, leading to significant morbidity and mortality due to respiratory insufficiency and associated anomalies. Clinically, neonates present with scoliosis, vertebral segmentation defects, and severe respiratory compromise, resulting in early neonatal death. These children have a unique patho-anatomy of volume depletion deformity of the thorax, resulting in thoracic insufficiency.

Combustion of surgical drapes during surgery is a rare event which can nonetheless lead to serious consequences. Iatrogenic burns caused by this complication are often deep and lead to functional and aesthetic sequelae. Nevertheless, awareness of the triggering factors and mechanisms, as well as knowledge of the proper use of various at-risk products such as alcohol-based antiseptic agents and compressed oxygen can reduce the incidence of these undesirable events.

Introduction: There is a risk of iatrogenic vascular injuries during robotic-assisted laparoscopic excision of diaphragmatic endometriosis. Although studies are limited, the first reported case of a suprahepatic inferior vena cava (IVC) injury during robotic diaphragmatic endometriosis excision was successfully treated using a fibrin sealant patch, preventing exsanguination and conversion to laparotomy.
Case Description: A 36-year-old female with a history of recurrent catamenial pneumothorax and two prior video-assisted thoracoscopic surgeries to treat diaphragmatic endometriosis presented to our clinic with right-sided shoulder pain and a chest tube in place.
Impact of a Quality Cardiopulmonary Resuscitation Coach on Pediatric Intensive Care Unit Resuscitation Teams.

Christine A. Schindler is a critical care pediatric nurse practitioner, critical care advanced practice provider program director, Children's Wisconsin/Medical College of Wisconsin, and a clinical professor, Marquette University, Milwaukee, Wisconsin.
Background: The quality cardiopulmonary resuscitation (CPR) coach role was developed for hospital-based resuscitation teams. This supplementary team member (CPR coach) provides real-time, verbal feedback on chest compression quality to compressors during a cardiac arrest.
Objectives: To evaluate the impact of a quality CPR coach training intervention on resuscitation teams, including presence of coaches on teams and physiologic metrics of quality CPR delivery in real compression events.
A five-finger mnemonic for teaching schoolchildren the theoretical components of adult basic life support: a modified reactive Delphi-guided development and memorability pilot test with schoolchildren.

Emergency Department, Maribor University Medical Centre, Maribor, Slovenia.
Background: A mnemonic is a cognitive aid frequently used in health-related education. The main goal of this study was to develop and test a 5-finger mnemonic for teaching schoolchildren the theoretical aspects of adult Basic Life Support (BLS) steps, a process rarely described in the context of instructing laypersons.
Methods: Experts from the European Resuscitation Council's Basic Life Support Science and Education Committee (ERC BLS SEC), specializing in teaching adult BLS, participated in the first phase of the pilot study.
