Abstract
Objective: To describe the detailed surgical procedure for open-chest CPR (OC-CPR) through a transdiaphragmatic (TD) approach during planned laparotomy and to evaluate the procedure time and damage to organs.
Animals: 7 mixed-breed canine cadavers.
Methods: The procedure was divided into 3 stages. Durations for each of the 3 stages of the procedure and total time from diaphragmatic incision to the end of Rumel tourniquet application were recorded. Subjective assessment of ease of procedures and postprocedural physical evaluation of thoracoabdominal organs were also performed.
Results: Mean time from diaphragmatic incision to pericardiotomy was 15.1 seconds (SD, 4.0). Performing 10 cardiac compressions took 12.0 seconds (SD, 1.8). Dissection of the aorta and application of a Rumel tourniquet took 130.4 seconds (SD, 52.2). The mean total time from start of first procedure to end of last procedure was 157.6 seconds (SD, 21.5). The mean length of diaphragmatic incision was 11.5 cm (SD, 2.2). Lung laceration was identified in one dog, and liver laceration was identified in another dog. The mean ease of pericardiotomy was 10, and application of a Rumel tourniquet was 4 (SD, 1.9). There was no instance of abdominal organs moving into the thoracic cavity during the procedure in any of the dogs.
Clinical relevance: Resuscitation techniques during TD OC-CPR can be performed with acceptable timing and effort, except for aortic Rumel tourniquet application, which was difficult and time consuming. Avoidable damage to thoracoabdominal organs can occur.
期刊介绍：
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
