Research comparing conventional litter and alternative perforated flooring (netting) systems is relatively limited under commercial production conditions. A comprehensive comparison of broiler production performances, welfare quality, and housing environment of two broiler houses with conventional litter and new perforated plastic floors was conducted over four flocks for eight months in eastern China. The two broiler houses each had 31,700 broilers per flock on average and were ventilated using a negative-pressure system...

OBJECTIVE: Patients postcoronary artery revascularization surgery often receives blood product transfusion, which could delay their intensive care unit and hospital discharge. We investigated our robotic-assisted direct coronary artery bypass (RADCAB) transfusion rate to determine whether performing the minimal invasive coronary surgery with percutaneous coronary intervention in one stage would increase the incidence of blood transfusion, morbidity, and length of stay. METHODS: Between November 2003 and November 2015, 483 consecutive patients underwent RADCAB surgery...

The purpose of this study is to determine the incidence of sinusitis in mechanically ventilated burn victims and to examine if the presence of inhalational injury increases the likelihood of developing sinusitis. The authors hypothesize that the incidence of sinusitis will be increased in burn victims who have concomitant inhalational injury. A retrospective chart analysis was performed on all patients who were admitted to the Nathan Speare Regional Burn Treatment Center over a 24-month time frame. Patients who were mechanically ventilated for greater than 24 hours were then selected, resulting in a total of 137 patients for analysis...

The authors sought to increase the number of days when burn service patients receive 100% of prescribed enteral nutrition. The authors first performed a retrospective review of 37 patients (group 1) receiving enteral nutrition. The authors then created and implemented a nurse-directed feeding algorithm, placing patients into three age groups addressing maximum hourly infusion rates, high residual limits, initiating feeding, refeeding residuals, and replacing formula. The authors then performed a prospective review of 37 patients (group 2) fed utilizing the new algorithm...

BACKGROUND: Spinal surgery in the prone position is accompanied by increased intrathoracic pressure and decreased respiratory compliance. This study investigated whether intraoperative lung protective mechanical ventilation improved lung function evaluated with pulmonary function tests in patients at risk of postoperative pulmonary complications (PPCs) after major spinal surgery in the prone position. METHODS: Seventy-eight patients at potential risk of PPCs were randomly assigned to the protective group (tidal volume; 6 mL/kg predicted body weight, 6 cm H2O positive end-expiratory pressure with recruitment maneuvers) or the conventional group (10 mL/kg predicted body weight, no positive end-expiratory pressure)...

REVIEW
Xuezheng Zhang, Mahmoud Attia Mohamed Kassem, Ying Zhou, Muhammad Shabsigh, Quanguang Wang, Xuzhong Xu
Obstructive sleep apnea (OSA) is one of the important risk factors contributing to postoperative airway complications. OSA alters the respiratory physiology and increases the sensitivity of muscle tone of the upper airway after surgery to residual anesthetic medication. In addition, the prevalence of OSA was reported to be much higher among surgical patients than the general population. Therefore, appropriate monitoring to detect early respiratory impairment in postoperative extubated patients with possible OSA is challenging...

Passive houses and other highly energy-efficient buildings need mechanical ventilation. However, ventilation systems in such houses are regarded with a certain degree of skepticism by parts of the public due to alleged negative health effects. Within a quasi-experimental field study, we investigated if occupants of two types of buildings (mechanical vs. natural ventilation) experience different health, wellbeing and housing satisfaction outcomes and if associations with indoor air quality exist. We investigated 123 modern homes (test group: with mechanical ventilation; control group: naturally ventilated) built in the years 2010 to 2012 in the same geographic area and price range...

BACKGROUND: The physiologic information contained in the video photoplethysmogram is well documented. However, extracting this information during challenging conditions requires new analysis techniques to capture and process the video image streams to extract clinically useful physiologic parameters. We hypothesized that heart rate, respiratory rate, and oxygen saturation trending can be evaluated accurately from video information during acute hypoxia. METHOD: Video footage was acquired from multiple desaturation episodes during a porcine model of acute hypoxia using a standard visible light camera...

BACKGROUND: We observed that increasing fresh gas flow (FGF) decreased exhaled tidal volume (VT) during pressure control ventilation (PCV). A literature search produced no such description whereby unintended VT changes occur with FGF changes during PCV. METHODS: To model an infant's lungs, 1 lung of a mechanical lung model (Dual Adult TTL 1600; Michigan Instruments, Inc, Grand Rapids, MI) was set at a compliance of 0.0068 L/cm H2O. An Rp50 resistor (27.2 cm H2O/L/s at 15 L/min) simulated normal bronchial resistance...

BACKGROUND: From 1990-2005 at Ochsner Medical Center in New Orleans, LA, cardiopulmonary bypass (CPB) was used only when necessary during lung transplantation surgeries. Ochsner's lung transplant program was closed for more than 4 years after Hurricane Katrina, and since the program's reestablishment in 2010, the majority of lung transplantation surgeries have been performed with the patient on CPB and with a median sternotomy incision. The purpose of this study was to compare the outcomes of the CPB and non-CPB groups...

This study tested the hypothesis that varying degrees of hemodynamic fluctuations seen after birth following immediate cord clamping were related to development of asphyxia with longer cord clamp-to-ventilation intervals, resulting in higher perinatal circulating levels of the catecholamines norepinephrine (NE) and epinephrine (Epi), and thus increased heart rate, blood pressures and cardiac contractility after birth. Anesthetized preterm fetal lambs were instrumented with 1) aortic (AoT) and pulmonary trunk (PT) micromanometers to obtain pressures and the maximal rate of pressure rise (dP/dtmax) as a surrogate measure of ventricular contractility, and 2) an AoT catheter to obtain samples for blood gas and catecholamine analyses...

Noninvasive positive-pressure ventilation (NPPV) might be superior to conventional mechanical ventilation (CMV) in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPDs). Inefficient clearance of respiratory secretions provokes NPPV failure in patients with hypercapnic encephalopathy (HE). This study compared CMV and NPPV combined with a noninvasive strategy for clearing secretions in HE and AECOPD patients.The present study is a prospective cohort study of AECOPD and HE patients enrolled between October 2013 and August 2015 in a critical care unit of a major university teaching hospital in China...
