BACKGROUND: The Neonatal Resuscitation Program (NRP) states that if adequate positive pressure ventilation (PPV) was given for a low heart rate (HR), the infant's HR should increase within the first 15 s of PPV. OBJECTIVE: To assess changes in HR in piglets with asphyxia-induced bradycardia. METHODS: Term newborn piglets (n=30) were anaesthetised, intubated, instrumented and exposed to 50 min normocapnic hypoxia followed by asphyxia. Asphyxia was achieved by clamping the tube until severe bradycardia (defined as HR at <u><</u>25% of baseline)...

Despite the increasing use of percutaenous valves, little is known about valve performance after external chest compression. We report a case of a compressed pulmonary Edwards Sapien® XT valve after resuscitation. With the patient on ECMO, successful redilatation was performed with unimpaired postprocedural valve function. We aim to increase the awareness for valve distortion after external chest compression with increasing numbers of transcatheter valvulations. We suggest that immediate re-evaluation of the implanted device via biplane fluoroscopy is mandatory after resuscitation in such cases...

On Earth, tissue weight generates compressive forces that press on body structures and act on the walls of vessels throughout the body. In microgravity tissues no longer have any weight and tissue compressive forces are lost, suggesting individuals who weigh more may show greater effects from microgravity exposure. One unique effect of long-duration microgravity exposure is the spaceflight-associated neuro-ocular syndrome (SANS) which can present with globe flattening, choroidal folds, optic disc edema, and a hyperopic visual shift...

A 46-year-old man presented with mass on chest x-ray along with a 6-month history of weight loss, dyspnea and cough. He was hypotensive and an echocardiogram showed large extra-cardiac mass compressing the right ventricular outflow tract resulting in features of cardiac tamponade. Chest computed tomography revealed a mediastinal mass invading the pericardium adjacent to right ventricular outflow tract. Biopsy of the mass confirmed primary monophasic synovial sarcoma. Chemotherapy and radiotherapy along with anti-inflammatories were given as surgery was too high risk due to the location of the tumour and pericardial involvement...

The new cardiopulmonary resuscitation (CPR) guideline emphasize the importance of chest compression, which was considered as the first step to CPR. The duration for CPR is usually limited to 30 minutes. With the development of new technology and evidence-based medicine, the success of extra longtime CPR has become possible, which is of great significance to some patients with cardiac arrest (CA), but the time limit has not been determined. On February 23rd in 2016, a 76-year-old female patient with respiratory and cardiac arrest who was on the third day after transurethral resection of bladder tumor (TUR-BT) was admitted to the intensive care unit of the General Hospital of Fushun Mining Bureau...

OBJECTIVE: To study the impact of interposed abdominal pulling-pressing cardiopulmonary resuscitation (IAPP-CPR) for patients with cardiac arrest (CA). METHODS: A prospective study was conducted. A total of 122 CA patients admitted to Department of Emergency of Shandong Provincial Mining Industry Group Company Central Hospital from July 2013 to December 2017 were enrolled. They were divided into standard cardiopulmonary resuscitation (S-CPR) group (n = 62) and IAPP-CPR group (n = 60) according to order of admission...

AIM: Our study aimed to compare cardiopulmonary resuscitation (CPR) performance among laypeople with different retraining intervals. METHODS: Ninety-six non-medical university students were randomly allocated into 3 groups after receiving initial CPR and automated external defibrillator (AED) training. Sixty participants completed the study. The participants in the 3-, 6-, and 12-month groups received the same retraining every 3-, 6-, and 12 months. An 80-minute retraining course comprised a video lecture and hands-on practice, with feedback from the instructors and the Resusci Anne® QCPR...

BACKGROUND: Little is known regarding the quality of cardiopulmonary resuscitation (CPR) performed by bystanders in out-of-hospital cardiac arrest (OHCA). We sought to determine quality of bystander CPR provided during OHCA using CPR quality data stored by Automated External Defibrillators (AEDs). METHODS: We used the Resuscitation Outcomes Consortium database to identify OHCA cases of presumed cardiac etiology where an AED was utilized. We then matched AED data to each case identified...

AIM: Cardiopulmonary resuscitation guidelines suggest the lower sternal half be compressed. However, stroke volume has been assumed to be maximized by compressing the 'point' (P_max.LV) beneath which the left ventricle (LV) is at its maximum diameter. Identifying 'personalized' P_max.LV on computed tomography (CT), we derived and validated rules to estimate P_max.LV using posteroanterior chest radiography (chest_PA). METHODS: A retrospective, cross-sectional study was performed with non-cardiac arrest (CA) adults who underwent chest_PA and CT within 1h (derivation:validation = 3:2)...

Cardiac arrest in the Catheterization Lab is a rare and unique scenario that is often logistically challenging. It often has dire prognosis especially in patients suffering from severe pre-existing illnesses (high risk patient) such as acute myocardial infarction with cardiogenic shock, or patients undergoing high risk procedures. As the number of complex interventional procedures increases, cardiac arrest in the cath lab will become more common and optimal management of this scenario is critical for both the patient and operator...

BACKGROUND: Recommendations regarding ventilation during cardiopulmonary resuscitation (CPR) are based on a low level of scientific evidence. We hypothesized that practices about ventilation during CPR might be heterogeneous and may differ worldwide. To address this question, we surveyed physicians from several countries on their practices during CPR. METHODS: We used a Web-based opinion survey. Links to the survey were sent by e-mail newsletters and displayed on the Web sites of medical societies involved in CPR practice from December 2013 to March 2014...

BACKGROUND: Immature teratoma in a mediastinal location is a rare disease that might present as a valve pathology. Germ cell tumors with mediastinal locations account for up to 6% of immature teratoma cases. We present a case of an immature teratoma located primarily in the anterior mediastinum that manifested solely through symptoms of pulmonary stenosis. CASE PRESENTATION: We report a case of a 20-year-old white man with an immature teratoma who presented with progressive exertional dyspnea...

Stereotactic body radiation therapy (SBRT) is associated with an increased risk of vertebral compression fracture. While bone is typically considered radiation resistant, fractures frequently occur within the first year of SBRT. The goal of this work was to determine if rapid deterioration of bone occurs in vertebrae after irradiation. Sixteen male rhesus macaque non-human primates (NHPs) were analyzed after whole-chest irradiation to a midplane dose of 10 Gy. Ages at the time of exposure varied from 45-134 months...

Out of hospital cardiac arrest (OHCA) remains not an uncommon occurrence in USA and rest of the world. However, the survival to discharge following an episode of OHCA in adults is still very disappointing at around 10%. Several areas of improvement including education of general public in early Cardio Pulmonary resuscitation (CPR) by bystander, chest compression first, and improvement of Emergency Medical response time have had a positive effect in outcomes and survival but much still needs to be done. Recently new data has emerged with regards to post resuscitation care and mild induced hypothermia (now preferably called; targeted temperature management {TTM}) and several advances have been made...

Out-of-Hospital Cardiac Arrest affects 350,000 Americans each year. Unfortunately, the national survival rate from such an event remains no better than 12% [1], though some communities do better and some worse [2]. The "Chain of Survival" concept has been accepted for decades and remains the roadmap for many communities in their efforts to improve their local survival rates from sudden cardiac death (SCD) (3-Chain of Survival concept). The key for this chain to be successful is the EARLY application of each link in the sequence of treating cardiac arrest...

Left atrial appendage aneurysm (LAA AN) is a rare disease entity, which can be congenital or acquired in nature. We report an adult patient with LAA AN presenting with anginal chest pain in whom live/real time three-dimensional transthoracic echocardiography (3DTTE) provided incremental value over the two-dimensional (2D) technique in providing a more comprehensive assessment of the lesion. A literature review of the salient features of LAA AN is also provided in a tabular form.

PURPOSE: Chest physiotherapy and tracheal suction cause sympathetic stimulation and increase heart rate (HR), mean arterial pressure (MAP) and intracranial pressure (ICP) which may have deleterious effect in the head injured. We planned to compare the effect of intravenous dexmedetomidine and lidocaine on intracerebral and systemic hemodynamic response to chest physiotherapy (CP) and tracheal suctioning (TS) in patients with severe traumatic brain injury (sTBI). METHODS: Prospective, randomized study in patients with sTBI, 18-60 years of age, undergoing mechanical ventilation and intraparenchymal ICP monitoring...

AIM: We investigated whether counting inflation breaths out loud during cardiopulmonary resuscitation (CPR) led to an earlier resumption of chest compressions. METHODS: In this randomised controlled manikin simulation study, conducted from February 2015 to April 2015, 32 fourth-year Korean medical students, equally divided into study and control groups, performed 10 cycles of 15:2 CPR while administering inflation breaths using a bag mask. The first study participant counted the number of inflation breaths out loud and the second study participant was told to perform chest compressions as soon as they heard their colleague say two...
