Active clinical trials for "Respiratory Insufficiency"

Rationale: Fluid overload is a common complication in children who are admitted to the pediatric intensive care for mechanical ventilation. Acute lung infection is a frequent cause for admission to the PICU and forms an uniform group with a single organ failure. In these critically ill children, fluid overload is associated with adverse outcome. Restricting the volume of fluids already in an early stage of ICU admission may prevent fluid overload during mechanical ventilation and thus improve clinical outcome. However, at the same time fluid restriction may interfere with appropriate energy and macronutrient intake that is needed for recovery. Objective: The main goal of this pilot study is to evaluate the feasibility of a restrictive fluid management protocol and investigate its effect on the occurrence of fluid overload in mechanically ventilated children with acute infectious lung disease. Study design: Single-center prospective randomized feasibility and pilot study in preparation of a multi-center randomized controlled trial (RCT). Study population: Mechanically ventilated children with (suspicion of) acute infectious lung disease admitted to the pediatric intensive care unit (PICU) of the Emma Children's Hospital, Academic Medical Center, Amsterdam. Intervention: Patients receive either liberal (control group) or a restrictive (experimental group) fluid treatment, while ensuring appropriate caloric intake. Main study parameters/endpoints: Primary outcomes are cumulative fluid balance and body weight during the first week of mechanical ventilation. Secondary outcomes (in preparation of the larger multi-center RCT) include: mortality, duration of mechanical ventilation and oxygenation indices. To determine the feasibility, in- and exclusion rate, adherence to treatment arms, need for fluid bolus, need for diuretics and hemodynamic indices as well as energy and protein intake are studied. Both fluid management protocols reflect a variant of current clinical practice, hence will not provide extra burden or risk to patients included in the study. Patients will be randomized to either of the fluid protocol arms on admission to the PICU (at start of mechanical ventilation). Patients included in the restrictive fluid treatment arm might have direct benefit from the study if indeed fluid overload is less common in this group.

Poor glycemic control in critically ill patients can increase their mortality, while safe and efficient glucose control is laborious and time-consuming. The Space GlucoseControl which is installed with eMPC(enhanced Model Predictive Control) can get the blood glucose target range safely and effectively through regulating insulin dose rate. This study is a random controlled trial involving the patients with mechanical ventilation in intensive care unit in order to evaluate the difference of safety and efficacy of blood glucose control between SGC directed and conventional treatment. At last, the trial results can determine whether the Space GlucoseControl can control blood glucose safely and effectively in the patients with mechanical ventilation in intensive care units.

The goal of this interventional crossover study in morbidly obese intubated and mechanically ventilated patients is to describe the respiratory mechanics and the heart-lung interaction at titrated positive end-expiratory pressure levels following a recruitment maneuver with transthoracic echocardiography and electric impedance tomography imaging.

Assessment of the effect and safety of noninvasive positive pressure ventilation for severe stable chronic obstructive pulmonary disease

Although non-invasive ventilation (NIV) usage has increased significantly over time in COPD exacerbation, a great percentage of patients (~30%) present contraindications to NIV or cannot tolerate it. Nasal high flow (NHF) has been introduced for the management of hypoxemic respiratory failure in adults with favorable effects on ventilation and respiratory mechanics. The above mentioned NHF positive effects has been observed also in stable COPD patients with or without chronic hypercapnia. In this study, the investigators hypothesize that NHF is not inferior to NIV for respiratory support in patients with COPD exacerbation and acute or acute on chronic hypercapnic respiratory failure.

Non emergent scheduled cesarean sections will be consented to participate in this study of patients who have screened negative for obstructive sleep apnea and who are also BMI>/= 35 to have capnography monitoring postoperatively. The capnography and pulse oximetry will be initiated in the post anesthesia care unit and be worn for 12-24 hours after delivery. Data will be retrieved after that time period in a deidentified fashion. Medication usage will be reviewed as well as the standard of care information from the duramorph monitoring will be retrieved.

Mechanical ventilation through an endotracheal tube is a lifesaving procedure for acute respiratory failure. However endotracheal intubation increases patient's discomfort and stress, and represents one of the most important predisposing factors for developing nosocomial bacterial pneumonia. In conscious and cooperative patients non invasive positive pressure ventilation (NPPV) is a safe and effective mean for treating patients with acute respiratory failure (ARF), improving gas exchanges and reducing the rate of complication related to mechanical ventilation. Facial mask, that is the conventional interface for NIV, may induce intolerance because of pain, discomfort or claustrophobia leading to discontinuation of noninvasive ventilation and endotracheal intubation. Thus the improvement of the interface between patient and ventilator seems crucial to achieve a good tolerance allowing the prolonged application of noninvasive ventilation. Attempting to improve tolerability of patients we used a new interface consisting in Helmet made in latex-free PVC. No prospective randomized controlled study has been published on the comparison between Continuous Positive Airways pressure (CPAP), delivered by an helmet and the medical treatment with Oxygen supplementation to treat early acute respiratory failure and acute lung injury. Aim of the present protocol is to compare the efficacy of CPAP delivered with helmet and conventional medical treatment with oxygen supplementation via Venturi mask, to prevent ETI in patients with early hypoxemic ARF ( paO2 /FiO2 below 300).

For children undergoing bone marrow transplantation, respiratory failure is a devastating complication, with mortality expectations well above 60%. The researchers have devised a novel strategy that may greatly improve survival. Hemofiltration, a continuous form of dialysis, was designed as a therapy for critically ill patients with kidney failure. A semi-permeable membrane removes plasma water and solutes (up to about 35,000 Daltons molecular weight). The researchers have treated immuno-compromised children with respiratory failure with hemofiltration. Many inflammatory molecules are of a size well below the limit of the filter. Hemofiltration might remove a critical amount of this inflammatory material, attenuating the unregulated inflammatory response that is central to the development of respiratory failure and progression to multiple organ failure and death. The researchers are conducting a multi-center trial of early continuous hemofiltration for respiratory failure in children following bone marrow transplantation. The researchers will analyze blood and ultrafiltrate using sensitive proteomic methods to detect several inflammatory biochemicals known to be active in this disease, looking for evidence that early active hemofiltration alters the inflammatory response. The researchers will test whether 'early' hemofiltration produces greater survival from respiratory failure in this vulnerable population.

Continuous positive airway pressure (CPAP) has been used successfully to promote extubation in the premature infant population. The two methods of CPAP to be examined are currently used by many institutions, yet no study has compared these methods to determine which is better in the population of newborns < 1500 grams (birth weight) at supporting extubation. This randomised controlled study will examine two types of CPAP: the Infant Flow System and the Bubble CPAP. This randomised controlled, single site, clinical study is to determine whether the Bubble CPAP or the Infant Flow System (IFS) CPAP is more effective at supporting the extubation in infants of birth weights < 1500 grams. Seventy-six infants will be randomised, immediately prior to extubation, to IFS or Bubble CPAP of 5 cmH2O. The primary outcome is successful extubation, defined as not reaching failure criteria for the 7 days post-extubation. Failure criteria are defined as pH < 7.25 and PCO2 > 65 mmHg or a sustained increase in FiO2 of 0.15.

Home non-invasive ventilators are daily used by patients with chronic respiratory failure. There are frequently used with warming and humidifying systems. These systems need to be cared for and frequently washed by the patient. The aim of this study is to evaluate if the humidifying system of home ventilators are colonized by microbiological germs.
