Randomized Controlled Trial Comparative Study Clinical Trial
An evaluation of a single chest physiotherapy treatment on mechanically ventilated patients with acute lung injury.
Acute lung injury is a lung pathology that presents frequently on the intensive care unit. Chest physiotherapy, in the form of endotracheal suction, alternate side-lying and manual hyperinflation, is usually given to patients with this condition with the intention of removing retained pulmonary secretions and recruiting collapsed distal lung units. Despite this common practice there is insufficient research on the effects of chest physiotherapy in patients with acute lung injury being ventilated mechanically. The aim of the present study was to further understanding of the effects of three modes of treatment in chest physiotherapy in an acute lung injury patient group. ⋯ Patients with acute lung injury are notably complex to nurse and may require protracted physiotherapy intervention, which may take many forms. As de-recruitment was the single most important event that occurred in the present study population, a prescriptive chest physiotherapy approach to treating mechanically ventilated patients with acute lung should be questioned and adapted accordingly.

Randomized Controlled Trial Clinical Trial
A comparison of the effects of manual and ventilator hyperinflation on static lung compliance and sputum production in intubated and ventilated intensive care patients.
Lung hyperinflation is a technique used by physiotherapists to mobilize and remove excess bronchial secretions, reinflate areas of pulmonary collapse and improve oxygenation. Hyperinflation may be delivered by the ventilator or manually, by use of a manual resuscitation circuit, depending upon the respiratory and cardiovascular status of the patient. The effects of manual hyperinflation, with respect to excess bronchial secretions and static lung compliance, have been well-established. There is, however, only limited evidence as to the efficacy of ventilator hyperinflation as a physiotherapy treatment technique. The purpose of the present study was to compare the effects of manual hyperinflation and ventilator hyperinflation on static pulmonary compliance and sputum clearance in stable intubated and ventilated patients. ⋯ Hyperinflation as part of a physiotherapy treatment can be performed with equal benefit using either a manual resuscitation circuit or a ventilator. Both methods of hyperinflation improve static pulmonary compliance and clear similar volumes of pulmonary secretions.

Comparative Study
Reliability of detecting 'onset of pain' and 'submaximal pain' during neural provocation testing of the upper quadrant.
Conflicting results have been reported with regard to the reliability of neural tissue provocation tests and it is unclear whether repeated testing affects the test results. In the present study, the stability and reliability of the occurrence of 'onset of pain' and 'submaximal pain' throughout the range of motion during neurodynamic testing was analysed, in both a laboratory and a clinical setting. ⋯ Pain provocation during neurodynamic testing is a stable phenomenon and the range of elbow extension corresponding with the moment of 'pain onset' and 'submaximal pain' may be measured reliably, both in laboratory and clinical conditions.

Respiratory complications remain a major cause of morbidity and mortality in the acute quadriplegic patient population. The literature has suggested that early insertion of a tracheostomy facilitated pulmonary management and an earlier discharge from the intensive care unit (ICU). Recently, a change in practice has meant that these patients are considered for extubation and intensive physiotherapy treatment, including an overnight on-call service, rather than tracheostomy. The aim of the present retrospective, case-controlled study was to determine if either practice resulted in a difference in length of stay in intensive care and if an on-call physiotherapy service for these patients was cost effective. ⋯ The results of this study suggest that if extubation and intensive physiotherapy is undertaken for suitable patients, the length of stay in intensive care can be significantly reduced. This represents a considerable cost saving for ICUs and more than covers the added cost of providing an after hours on-call physiotherapy treatment service. A prospective evaluation is required to confirm these findings.

The performance of manual hyperinflation by physiotherapists can be improved by the availability of a pressure manometer. The present study aimed to test whether these benefits could be maintained when the manometer is withdrawn and whether the availability of a manometer affects the pressures delivered under changing respiratory compliances. ⋯ The availability of a pressure manometer negates the influence of respiratory compliance on the achievement of target peak airway pressures during manual hyperinflation in the laboratory environment, however these benefits are not retained when feedback is withdrawn. Therefore, it is recommended that a pressure manometer should be routinely available during manual hyperinflation in clinical practice to optimize treatment safety and effectiveness.
