Artificial ventilation for basic life support leads to hyperventilation in first aid providers.

2003

The 'Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care - International Consensus on Science' recommend an artificial ventilation volume of 10 ml/kg bodyweight (equivalent to a tidal volume of 700-1000 ml) without the use of supplemental oxygen in adults with respiratory arrest. For first aid providers using the mouth-to-mouth or mouth-to-nose-ventilation technique, respectively, a ventilation volume of approximately 9.6 l/min results. Additionally, a deep breath is recommended before each ventilation to increase the end-expiratory oxygen concentration of the air exhaled by the first aid provider. To investigate the effects of these recommendations in health…

Dynamic computed tomography: a novel technique to study lung aeration and atelectasis formation during experimental CPR

2002

Objective: To develop an image based technique to study the effect of different ventilatory strategies on lung ventilation and alveolar recruitment during cardiopulmonary resuscitation (CPR). Design: (1) Technical development of the following components: (a) construction of an external chest compression device, which does not interfere with CT imaging, and (b) development of a software tool to detect lung parenchyma automatically and to calculate radiological density parameters. (2) Feasibility studies: three strategies of CPR ventilation were performed and imaged in one animal each (pigs, 25 kg): volume-constant ventilation (VCV), no ventilation, or continuous airway pressure (CPAP). One m…

Effektivit�t pr�klinischer Notfallversorgung Fiktion oder Fakt?

1996

The current increase in the cost of health care must be considered as a severe threat to the prehospital emergency services system. Two examples have been selected--the patient with polytrauma and the patient in cardiac arrest--to demonstrate the dilemma between a need for objective data and the requirements of emergency patients. Study results obtained in trauma patients indicating that total prehospital time, including scene time, is correlated to patient outcome have led to the conclusion that at the scene treatment by emergency physicians may be dispensable. It has, however also been demonstrated that the time required for medical treatment at the scene is equivalent to 20% of the total…

Quantitative EEG during Early Recovery from Hypoxic-Ischemic Injury in Immature Piglets: Burst Occurrence and Duration

1999

This study examined the course of EEG recovery in an animal model of hypoxic-ischemic injury. The model used periods of hypoxia, room air and asphyxia to induce cardiac arrest. One-week-old piglets (n = 16) were exposed to a period of hypoxia, room air and complete asphyxia for 7 minutes. After cardiac arrest and resuscitation, two EEG features were evaluated as prognostic indicators of behavioral outcome as assessed by a neuroscore at 24 hours after insult. A prominent EEG feature was the number and duration of bursts evident during recovery. Episodes of bursting were detected through the thresholds on sustained periods of elevated power. After the animal was resuscitated, the EEG was moni…

Il bambino “sovrano” e l’adulto “irrisolto”. Tempi di crescita familiare ed educazione

2019

“Sovereign” child, apathetic adolescents, kidult, young adult, “unresolved” adult, forms of “pseudo-integrity” of the elderly are some expressions that show phenomena that are radically changing, along with the identity of the family, times of growth of the different generations, and the sense of belonging to a historical community. Profound transformations involved in the transitions of the family life cycle are also visible in the disappearance of some phases of family growth in favor of others. Through a pedagogical reflection on these phenomena, this contribution aims to underline some aspects of the ways of understanding education and growth in the family of late modernity, for the pur…

Portal vein thrombosis and Budd-Chiari syndrome as onset of polycythemia vera

2013

Budd-Chiari syndrome may be defined as a heterogeneous group of vascular disorders characterized by obstruction of hepatic venous return to the level of hepatic venules, supra-hepatic veins, inferior vena cava or right atrium. The main cause of this syndrome is represented by myeloproliferative diseases and, in particular, by polycythemia vera. The latter may cause multiple splanchnic thrombosis, including portal vein thrombosis, particularly important for its clinical outcomes (ascites, collateral vessels genesis, etc.). We report 2 cases of a Budd-Chiari syndrome induced by polycythemia vera characterized by an abnormal clinical onset, both as regards subjects’ age (29 and 39 years old, r…

OX40 expression in tumor-associated Tregs as a potential prognostic biomarker and immunotherapeutic target in ovarian cancer.

2015

e16576 Background: Treatment of ovarian cancer (OC) remains very challenging, with 80-85% of the cases still dying after relapse to standard chemotherapy, and novel treatments are urgently needed. Expansion of regulatory T cells (Tregs) is considered the major factor limiting immune responses to OC. Agonist antibodies against the co-stimulatory receptor OX40 have recently demonstrated to abrogate Treg functions and are under clinical evaluation. We thus studied whether OX40 constituted a valid target of OC-associated Tregs. Methods: Treg immunophenotypic analyses were performed by flow cytometry in ascites and OC specimens and studied in association with patients’ outcome Results: CD4+CD25+…

Catumaxomab with and without prednisolone in patients with malignant ascites due to epithelial cancer: Results from the phase IIIb CASIMAS study

2012

e13097^ Background: The primary objective of this study was to compare catumaxomab with prednisolone (CP) to catumaxomab without prednisolone (C) as 3-hour intraperitoneal (i.p.) infusion by demonstrating superiority for safety and non-inferiority for efficacy of the CP arm. Methods: 219 patients were randomized to catumaxomab plus premedication of 25 mg prednisolone (111 pts) or to catumaxomab alone (108 pts). The primary endpoint was the composite safety score (CSS) summarizing the worst CTCAE grades for the main TEAEs (pyrexia, nausea, vomiting, and abdominal pain). A potential impact of prednisolone on efficacy was assessed by the co-primary endpoint puncture-free survival (PuFS). Furt…
