Physiological Changes in Subjects Exposed to Accidental Hypothermia: An Update.

Background: Accidental hypothermia (AH) is an unintended decrease in body core temperature (BCT) to below 35°C. We present an update on physiological/pathophysiological changes associated with AH and rewarming from hypothermic cardiac arrest (HCA).

Temperature Regulation And Metabolism: Triggered by falling skin temperature, Thyrotropin-Releasing Hormone (TRH) from hypothalamus induces release of Thyroid-Stimulating Hormone (TSH) and Prolactin from pituitary gland anterior lobe that stimulate thyroid generation of triiodothyronine and thyroxine (T4).

Rewarming From Hypothermic Cardiac Arrest Applying Extracorporeal Life Support: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis aims at comparing outcomes of rewarming after accidental hypothermic cardiac arrest (HCA) with cardiopulmonary bypass (CPB) or/and extracorporeal membrane oxygenation (ECMO). Literature searches were limited to references with an abstract in English, French or German. Additionally, we searched reference lists of included papers.

POSTOPERATIVE PULMONARY COMPLICATIONS AND ACUTE RESPIRATORY DISTRESS SYNDROME -BETTER PREVENT THEN TREAT.

In parallel with increasing number, duration and extensiveness of surgical interventions, postoperative pulmonary complications (PPC) and acute respiratory distress syndrome (ARDS) remain the major challenges for anesthesiologists and surgical ICU physicians. PPC and ARDS have multiple risk factors that should be recognized early and modifed within the appropriate "time window ". Today we possess reliable models (ARISCAT LIPS, EALI etc.

Inhibitor of neuronal nitric oxide synthase improves gas exchange in ventilator-induced lung injury after pneumonectomy.

Background: Mechanical ventilation with high tidal volumes may cause ventilator-induced lung injury (VILI) and enhanced generation of nitric oxide (NO). We demonstrated in sheep that pneumonectomy followed by injurious ventilation promotes pulmonary edema. We wished both to test the hypothesis that neuronal NOS (nNOS), which is distributed in airway epithelial and neuronal tissues, could be involved in the pathogenesis of VILI and we also aimed at investigating the influence of an inhibitor of nNOS on the course of VILI after pneumonectomy.

Increased extravascular lung water reduces the efficacy of alveolar recruitment maneuver in acute respiratory distress syndrome.

Introduction. In acute respiratory distress syndrome (ARDS) the recruitment maneuver (RM) is used to reexpand atelectatic areas of the lungs aiming to improve arterial oxygenation. The goal of our paper was to evaluate the response to RM, as assessed by measurements of extravascular lung water index (EVLWI) in ARDS patients.
