2023 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations: Summary From the Basic Life Support; Advanced Life Support; Pediatric Life Support; Neonatal Life Support; Education, Implementation, and Teams; and First Aid Task Forces.

The International Liaison Committee on Resuscitation engages in a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation and first aid science. Draft Consensus on Science With Treatment Recommendations are posted online throughout the year, and this annual summary provides more concise versions of the final Consensus on Science With Treatment Recommendations from all task forces for the year. Topics addressed by systematic reviews this year include resuscitation of cardiac arrest from drowning, extracorporeal cardiopulmonary resuscitation for adults and children, calcium during cardiac arrest, double sequential defibrillation, neuroprognostication after cardiac arrest for adults and children, maintaining normal temperature after preterm birth, heart rate monitoring methods for diagnostics in neonates, detection of exhaled carbon dioxide in neonates, family presence during resuscitation of adults, and a stepwise approach to resuscitation skills training. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the quality of the evidence, using Grading of Recommendations Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence-to-Decision Framework Highlights sections. In addition, the task forces list priority knowledge gaps for further research. Additional topics are addressed with scoping reviews and evidence updates.

Optimising telecommunicator recognition of out-of-hospital cardiac arrest: A scoping review.

Aim: To summarize existing literature and identify knowledge gaps regarding barriers and enablers of telecommunicators' recognition of out-of-hospital cardiac arrest (OHCA). Methods: This scoping review was undertaken by an International Liaison Committee on Resuscitation (ILCOR) Basic Life Support scoping review team and guided by the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR). Studies were eligible for inclusion if they were peer-reviewed and explored barriers and enablers of telecommunicator recognition of OHCA. We searched Ovid MEDLINE® and Embase and included articles from database inception till June 18th, 2024. Results: We screened 9,244 studies and included 62 eligible studies on telecommunicator recognition of OHCA. The studies ranged in methodology. The majority were observational studies of emergency calls. The barriers most frequently described to OHCA recognition were breathing status and agonal breathing. The most frequently tested enabler for recognition was a variety of dispatch protocols focusing on breathing assessment. Only one randomized controlled trial (RCT) was identified, which found no difference in OHCA recognition with the addition of machine learning alerting telecommunicators in suspected OHCA cases. Conclusion: Most studies were observational, assessed barriers to recognition of OHCA and compared different dispatch protocols. Only one RCT was identified. Randomized trials should be conducted to inform how to improve telecommunicator recognition of OHCA, including recognition of pediatric OHCAs and assessment of dispatch protocols.

Parenchymal-sparing hepatectomy for multiple bilobar colorectal liver metastases in a Jehovah's witness: a case report.

Parenchymal-sparing hepatectomy (PSH), though technically challenging, is emerging as a choice of treatment for colorectal liver metastases (CRLM). PSH in Jehovah's witness (JW) patients, for whom transfusion is not an option, involves complex surgical and medicolegal issues. A 52-year-old JW male with synchronous, multiple, bilobar liver metastases from a rectal adenocarcinoma was referred following neoadjuvant chemotherapy. At surgery, 10 metastatic deposits were observed and confirmed by intraoperative ultrasonography. Parenchymal-sparing non-anatomical resections were performed using a cavitron ultrasonic aspirator with the application of intermittent Pringle maneuvres. Histology confirmed multiple CRLMs with tumor-free resection margins. PSH is increasingly employed for CRLMs to preserve residual liver volume and minimize morbidity without compromising oncological outcomes. It is technically challenging, especially in the presence of bilobar, multi-segmental disease. This case illustrates the feasibility of performing complex hepatic surgery in special patient groups by meticulous planning and preparation involving multiple specialties and the patient.

Infarct Like Necrosis of Colorectal Liver Metastasis Without Chemotherapy: A Rare Phenomenon.

Usual type necrosis (UN) and infarct like necrosis (ILN) occur in CRLMs. ILN is a rare form of necrosis in colorectal liver metastases which is usually seen following chemotherapy. De novo occurrence of ILN is a very rare phenomenon. ILN in CRLM without adjuvant chemotherapy following colorectal resection was not described previously. We describe the presence of complete ILN in a solitary metachronous liver metastasis from right colonic adenocarcinoma without prior chemotherapy.
