a recent issue of Critical Care, Bojan and colleagues [1] reported their experience with early initiation of high-frequency oscillatory ventilation (HFOV) in pediatric cardiac surgery that demonstrated shorter mechanical ventilation times and intensive care stays. Acute lung injury is common in adult patients undergoing surgery, yet there is scant reporting of the intraoperative utility of HFOV...

BACKGROUND The Laryngeal Tube Sonda (LTS) is a supraglottic airway which, like the ProSeal Laryngeal Mask Airway (PLMA), incorporates a drain tube. We compared the performances of LTS and PLMA during controlled ventilation anaesthesia. METHODS The devices were studied in 32 ventilated patients by randomized crossover trial. Primary outcome was airway seal pressure. Secondary outcomes included...

BACKGROUND AND OBJECTIVES Late pressure angioedema is a rare form of angioedema in which light pressure stimulus can lead to edema after 1-12h. This uncommon and unreported entity is especially important in patients who undergo general anesthesia, for whom the usual harmless supine position, intravenous catheter insertion, standard monitoring, airway management and ventilation can lead to life ...

Potentially harmful effects of positive pressure mechanical ventilation have been recognized since its inception in the 1950s. Since then, the risk factors for and mechanisms of ventilator-induced lung injury (VILI) have been further characterized. Publication of the ARDSnet tidal volume trial in 2000 demonstrated that a ventilator strategy limiting tidal volumes and plateau pressure in patient...

BACKGROUND The insertion of suction devices through endotracheal tubes (ETTs) increases airway resistance and the subsequent suctioning may reduce airway pressures and facilitate atelectasis. The aim of this study was to investigate how airway pressures and tidal volumes change when different combinations of suction equipment and ETT sizes are used, and to what extent unfavorable effects can be...

Pressure controlled ventilation (PCV) is an alternative mode of ventilation which is used widely in severe respiratory failure. In this study, PCV was used for one-lung anaesthesia and its effects on airway pressures, arterial oxygenation and haemodynamic state were compared with volume controlled ventilation (VCV). We studied 48 patients undergoing thoracotomy. After two-lung ventilation with ...

Background: Humidified heated high flow nasal cannula (HHHFNC), nasal continuous positive airway pressure (NCPAP), and nasal intermittent positive pressure ventilation (NIPPV) are three nasal non-invasive ventilation methods. The purpose of this study was to compare these three methods in decreasing intubation and mechanical ventilation rate in preterm neonates with respiratory distress syndrom...

OBJECTIVE To compare the effectiveness of high-frequency oscillatory ventilation with conventional mechanical ventilation in pediatric patients with respiratory failure. SETTING Five tertiary care pediatric intensive care units. DESIGN A prospective, randomized, clinical study with crossover. PATIENTS Seventy patients with either diffuse alveolar disease and/or airleak syndrome were rando...

Introduction: One of the major concerns in laryngeal laser surgery is the risk of airway fire. The introduction ofwrapped tubes and metal tubes has reduced the fire hazards. However, these tubes are expensive and do not provide convenient access to the surgical field. There are few laboratory studies addressing the resistance of polyvinylchloride tubes against ignition in the given circum...

Background: Preterm labor is at risk for respiratory distress syndrome (RDS) and sometimes requires to mechanical ventilation (MV) and surfactant therapy. Continuous positive airway pressure (CPAP) and Nasal Continuous positive airway pressure (NCPAP) are the methods of respiratory support especially for using in RDS of neonates. In other method surfactant is administered to babies via tracheal...
