1. The Effect of Low Tidal Volume Ventilation on Inflammatory Cytokines During Cardiopulmonary Bypass
Abstract Introduction: Halting ventilation during cardiopulmonary bypass (CPB) is implemented to operate in a less bleeding setting. It sustains a better visualization of the operation area and helps to perform the operation much more comfortably. On the other hand, it may lead to a series of postoperative lung complications such as atelectasis and pleural

2. Hemodynamic outcome of different ventilation modes in laparoscopic surgery with exaggerated trendelenburg: a randomised controlled trial
Abstract Purpose: To compare hemodynamic effects of two different modes of ventilation (volumecontrolled and pressure-controlled volume guaranteed) in patients undergoing laparoscopic gynecology surgeries with exaggerated Trendelenburg position. Methods: Thirty patients undergoing laparoscopic gynecology operations were ventilated using either volume-contr

3. Effect of mechanical ventilation during cardiopulmonary bypass on oxidative stress: a randomized clinical trial
Abstract Background: Cardiopulmonary bypass (CPB) causes systemic oxidative stress response and endothelial damage in systemic organs. We investigated the effects of positive end-expiratory pressure (PEEP) and mechanical ventilation (MV) applications on oxidative stress in CPB. Methods: Seventy-one patients were recruited and 60 completed the study. Random

4. Características y resultados de los pacientes infectados con nCoV19 con requerimiento de ventilación mecánica invasiva en la Argentina
RESUMEN Objetivo: El coronavirus ha emergido este año como causa de neumonía viral. Una de las principales características es su rápida transmisión y su potencial severidad. El objetivo de este estudio de serie de casos es describir las características clínicas de los pacientes con confirmación de enfermedad por coronavirus (COVID-19) admitidos en d

5. Efecto de la PEEP sobre el componente resistivo inspiratorio en pacientes con sindrome de distrés respiratorio agudo ventilados a bajo volumen corriente
ABSTRACT Objective: To describe the behavior of inspiratory resistance components when positive end-expiratory pressure (PEEP) increases in patients with acute respiratory distress syndrome under a protective ventilation strategy. Methods: In volume-controlled mode, at 6mL/kg and constant flow, end-inspiratory occlusions were performed at 0, 5 10, 15 and 2

6. Hemodynamic variables in piglets anesthetized with isoflurane or propofol, kept under spontaneous ventilation and FIO2 of 0.5
RESUMO O objetivo deste estudo foi avaliar comparativamente os efeitos do propofol ou do isoflurano sobre as variáveis hemodinâmicas em leitões que receberam fração inspirada de oxigênio (FIO2) de 0,5 sob ventilação espontânea. Dezesseis leitões, pesando 16±1,1kg, foram divididos aleatoriamente em dois grupos: GI (isoflurano e FIO2 de 0,5) e GP (p

7. Hypercapnia attenuates ventilator-induced lung injury through vagus nerve activation
Abstract Purpose: To investigate the role of vagus nerve activation in the protective effects of hypercapnia in ventilator-induced lung injury (VILI) rats. Methods: Male Sprague-Dawley rats were randomized to either high-tidal volume or low-tidal volume ventilation (control) and monitored for 4h. The high-tidal volume group was further divided into either

8. Evaluation of volume responsiveness by pulse pressure variability and inferior vena cava dispensability index at different tidal volumes by mechanical ventilation
This study investigated the effects of tidal volume (TV) on the diagnostic value of pulse pressure variation (PPV) and the inferior vena cava dispensability index (IVC-DI) for volume responsiveness during mechanical ventilation. In patients undergoing elective surgery with mechanical ventilation, different TVs of 6, 9, and 12 mL/kg were given for two min. Th

9. The Effect of Continuous Ventilation on Thiol-Disulphide Homeostasis and Albumin-Adjusted Ischemia-Modified Albumin During Cardiopulmonary Bypass
Abstract Objective: To investigate the effect of continuous lung ventilation with low tidal volume on oxidation parameters, such as thiol/disulphide homeostasis and albumin-adjusted ischemia-modified albumin (AAIMA), during cardiopulmonary bypass (CBP) in coronary artery bypass grafting (CABG). Methods: Seventy-four patients who underwent elective CABG wit

10. Decreased respiratory performance of children and adolescents with myelomeningocele who use a wheelchair – preliminary data
Myelomeningocele (MMC) is a neural tube defect that often causes spinal cord injury at the thoracolumbar region, as well as sensory and motor paralysis in the lower limbs. This leads to continuous use of a wheelchair and, consequently, a sedentary lifestyle, predisposition to muscle weakness, cardiovascular and respiratory disorders, obesity, and structural

11. The role of maximum compressed thickness of the quadriceps femoris muscle measured by ultrasonography in assessing nutritional risk in critically-ill patients with different volume statuses
RESUMO OBJETIVO Neste estudo observacional prospectivo, objetivamos investigar o papel da espessura do músculo quadríceps femoral (QFMT) comprimido (mc) e não comprimido (uc) medida pela ultrassonografia (USG) na detecção do risco nutricional em pacientes de terapia intensiva (ICPs) com status de volume diferente. MÉTODOS Cinquenta e cinco paciente

12. Effect of intraoperative lung-protective mechanical ventilation on pulmonary oxygenation function and postoperative pulmonary complications after laparoscopic radical gastrectomy
This study aimed to observe the effects of lung-protective ventilation (LPV) on oxygenation index (OI) and postoperative pulmonary complications (PPCs) after laparoscopic radical gastrectomy in middle-aged and elderly patients. A total of 120 patients who were scheduled to undergo laparoscopic radical gastrectomy with an expected time of >3 h were randomly d
