STUDY OBJECTIVE To evaluate right ventricular dimensions and function by echocardiography in anesthetized patients during superimposed high-frequency jet ventilation (HFJV). DESIGN Prospective clinical study. SETTING University hospital operating room. PATIENTS 20 ASA physical status I patients undergoing elective minor otorhinolaryngological surgery,(More)
Die superponierte Hochfrequenz Jet-Ventilation (SHFJV) wurde als alternative Beatmungstechnik bei Patienten mit Lungenversagen eingesetzt. Um diese Beatmungsform optimal applizieren zu können, wurde ein spezieller Jet-Adapter entwickelt. Methoden: Dieser Jet-Adapter aus Kunststoff besteht aus einem T-Stück mit vier Kunststoffkanülen und kann an jeden(More)
BACKGROUND Recruitment maneuvers performed in early adult respiratory distress syndrome remain a matter of dispute in patients ventilated with low tidal volumes and high levels of positive end-expiratory pressure (PEEP). In this prospective, randomized controlled study the authors evaluated the impact of recruitment maneuvers after a PEEP trial on(More)
OBJECTIVE To evaluate the interaction of recruitment maneuvers and prone positioning on gas exchange and venous admixture in patients with early extrapulmonary acute respiratory distress syndrome ventilated with high levels of positive end-expiratory pressure. We hypothesized that a sustained inflation performed after 6 hrs of prone positioning would induce(More)
Background: Adequate humidification in long-term jet ventilation is a critical aspect in terms of clinical safety. Aim: To assess a prototype of an electronic jet-ventilator and its humidification system. Methods: Forty patients with respiratory insufficiency were randomly allocated to one of four groups. The criterion for inclusion in this study was(More)
OBJECTIVE To evaluate patients without prior pulmonary disease after cardiac surgery and to determine whether resistive unloading by automatic tube compensation, pressure support ventilation, and continuous positive airway pressure has different effects on oxygen consumption, breathing pattern, gas exchange, and hemodynamics. DESIGN Prospective,(More)
UNLABELLED We report the occurrence of an intraoperative left atrial hematoma during coronary artery bypass grafting surgery. Echocardiography proved to be of great help in diagnosis and monitoring of this patient. After severe hemodynamic impairment the patient recovered and could be transferred on postoperative day eight. Follow-up examination showed no(More)
Brain natriuretic peptide is a neurohormone used for estimation of left ventricular wall tension and volume overload. We describe the use of this parameter in a postoperative cardiac surgery patient for detection and monitoring of left ventricular failure in a postoperative intensive care unit at a tertiary care center. Left ventricular failure was detected(More)
UNLABELLED Despite advances and technical developments in the area of intensive care medicine it has not been possible to lower the mortality of patients with pulmonary insufficiency. Therefore, alternative ventilation strategies have been developed and applied. One of these ventilation techniques is superimposed high-frequency jet ventilation (SHFJV). For(More)
