Filter by:Prospective multicenter randomized controlled trial. Individualized perioperative open lung ventilatory approach in emergency abdominal laparotomy.
This proposal will test the feasibility of implementing an assist volume control ventilation protocol in patients receiving mechanical ventilation in the medical intensive care unit. The trial will consist of a before-and-after trial design of block assignment to either adaptive pressure control (baseline) or assist volume control . This is a feasibility study looking at the management of patients in the ventilator.
The peak inspiratory pressure during face mask ventilation for general anesthesia is closely correlated with gastric insufflation. High pressure increases the amount of air in stomach and low pressure could decrease the tidal volume, therefore ideal pressure means the pressure guarantee adequate ventilation with minimal gastric insufflation. The aim of this study is finding the proper pressure and mode of face mask ventilation in pediatric patients.
Mechanical ventilation can cause damage to the lung parenchyma, this is known as ventilatory induce lung injury (VILI).To avoid this damage, ventilatory strategies have been created, focused on the reduction of tidal volume, airway pressures and use of PEEP (positive end-expiratory pressure), which together are called "protective ventilation". Although ventilation with protective parameters seems to reduce VILI in one-lung ventilation, the optimal parameters are not clear.
Evaluation of effects of an endoscopic bite block on mask ventilation. In the present study, expiratory tidal volume and minute ventilation are measured under same pressure controlled mode in ventilator with three kinds of holding a mask. ( by one hand, one hand with an endoscopic bite block and two hand hold.)
The capnodynamic method non-invasively calculates effective lung volume (ELV) continuously during surgery. In this study ELV is compared to functionalresidual capacity (FRC) measured with Nitrogen Multiple Breath Wash out (NMBW) at 0 and 5 cm H2O Positive End Expiratory Pressure (PEEP) in patients scheduled for neck surgery at the Karolinska University Hospital, Solna, Sweden.
This study aims at assessing the respiratory mechanics of intubated patients in intensive care unit.
This is a single centre study. The investigators intend to recruit 20 subjects over 4 months. Patients undergoing laparoscopic abdominal surgery for cholecystectomy, laparoscopic gynaecological surgery and laparoscopic urologic procedures either as day surgery, same day admission or in patients, will be included in the study. Patients will be identified at the time of listing for surgery and referred to study team, which in turn will recruit the patients. Informed consent will be obtained at the time of recruitment and a copy of consent with details of principal investigator would be provided to subjects. All data collection will be done intraoperative. Patient would be followed up once at day 3 post op period. If patients have any complications related to the study, they will be followed up weekly until the complication is resolved.
Mechanical ventilation can be used to impose a completely regular pattern of breathing frequency and inflation volume on the patient for as long as required. This would considerably improve the reproducibility of the internal motion parameters, and thus facilitate the implementation of respiratory-synchronized techniques such as gating, tracking and four-digital optimization.
The study compares two different ventilation modes, Pressure support ventilation vs. Neuronally Adjusted Ventilatory Assist, in postcardiac surgery patients. Of special interest is shunt and alveolar deadspace and ventral vs. dorsal ventilation.
