Randomized Controlled Trial Comparative Study Clinical TrialThree different mask physiotherapy regimens for prevention of post-operative pulmonary complications after heart and pulmonary surgery.
An investigation into the incidence of post-operative complications after thoracic surgery with 3 different physiotherapy masks. ⋯ There was no statistically significant difference between the treatments: continuous positive airway pressure (CPAP), positive expiratory pressure (PEP), and inspiratory resistance - positive expiratory pressure (IR-PEP) on post-operative complications. Any of the three treatments may be used as supplement to standard chest physiotherapy.

Histologic aspects of pulmonary barotrauma in critically ill patients with acute respiratory failure.
To describe histologically pulmonary barotrauma in mechanically ventilated patients with severe acute respiratory failure. ⋯ Underlying histologic lesions responsible for clinical lung barotrauma consist of pleural cysts, bronchiolar dilatation, alveolar overdistension and intraprenchymal pseudocysts. Mechanical ventilation appears to be an aggravating factor, particularly when high peak airway pressures and large tidal volumes are delivered by the ventilator.

Review Case ReportsTrends from the United States with end of life decisions in the intensive care unit.
To describe the changes that have occurred in the United States since medicine has moved away from a paternalistic model to one that promotes patient autonomy and self-determination. To discuss the implications for cardiopulmonary resuscitation (CPR) and the increasing use of when not to perform CPR and other life-sustaining therapies. To describe the various interpretations of the ritual term Do-Not-Resuscitate (DNR) and to introduce the concept of futility in the context of non-beneficial over-treatment and discriminatory under-treatment. ⋯ Although Health Proxy in its current formulation has been disappointing, there is a clear trend for wider application of DNR and for more active discussions about withholding or forgoing other life-sustaining therapies. DNR has a different interpretation late into the ICU course (> 72 h) than when applied at or shortly after ICU admission. Late in the ICU course, it has been decided by the medical team and family or surrogate decision maker/Health Proxy that the patient has failed or is in the process of failing aggressive ICU therapy. Early use of DNR may be related to limitations based on pre-existing chronic or subacute disease burden or an unwillingness to proceed with a full ICU course of therapy. It is unclear how Ethics Committees, risk management and hospital administrators, national practice guidelines, governmental sponsored health care reform will interface with the highly complex individual patient--physician--family--Health Proxy interface as practiced in the United States. Dialogue between the Society of Critical Care Medicine and the European Society of Critical Care Medicine and among interested physicians could provide a format for a multi-cultural context to discuss end of life issues in the ICU setting.

Review Case ReportsSudden death revealing Chiari type 1 malformation in two children.
We report the first two fatal cases of sudden unprovoked cardiorespiratory arrest in children with previously undiagnosed Arnold-Chiari type 1 malformation. This diagnosis should be considered in children with unexplained cardiorespiratory arrest. The risk of sudden death in Arnold-Chiari type 1 malformation reinforces the indication for early neurosurgical procedure.

Randomized Controlled Trial Comparative Study Clinical TrialNon-invasive modalities of positive pressure ventilation improve the outcome of acute exacerbations in COLD patients.
1) To compare the clinical usefulness of both non-invasive pressure support ventilation (NPSV) and non-invasive intermittent positive pressure ventilation in assist-control (A/C) mode (NIPPV) in chronic obstructive lung disease (COLD) patients with acute hypercapnic respiratory failure: 2) to compare retrospectively the usefulness of non-invasive mechanical ventilation (NMV) with standard medical therapy alone. ⋯ Non-invasive mechanical ventilation performed either by NPSV or NIPPV may improve the outcome of acute exacerbations of COLD, as compared to medical therapy alone. NPSV seems to be more acceptable to patients in comparison with NIPPV.
