AIM Fast direct decompression surgery for treatment of severe head injury often results in intraoperative and postoperative complications. Controlled decompression may help prevent these complications. This preliminary study aims to compare the effects of controlled and conventional decompression in patients with severe head injury. MATERIAL AND METHODS A total of 128 patients with severe hea...

In this study we assessed the reliability of a tilting-board grip score as a measure of decompression sickness in rats. In experiments using a hyperbaric compression/decompression protocol, rats were observed for signs of decompression sickness and their grip strength measured on a tilting particle board hinged to a metal frame. Angles at which rats lost grip were converted to gravitational vec...

The present study was initiated in order to determine the effect of decompression profiles on bubble formation following surface decompression using oxygen. Following an air dive to 496 kPa (130 fsw) for 90 minutes, three different profiles were tested in the pig; a USN staged decompression profile, a profile using linear continuous decompression with the same total decompression time as the US...

STUDY DESIGN A systematic review of the literature for clinical and preclinical evidence related to timing of decompression following spinal cord injury (SCI). OBJECTIVE A review of the literature in search of consensus on what constitutes the ideal time frame for surgical management of SCI. SUMMARY OF BACKGROUND DATA Optimal timing for surgical management of SCI remains poorly defined. Des...

BACKGROUND Many occupational diving groups have substantially different diving patterns to those for which decompression schedules are validated. AIMS To evaluate tuna farm occupational diving practice against existing decompression models and describe a method for collecting and modelling self reported field decompression data. METHODS Machine readable objective depth/time profiles were ob...

OBJECTIVE To analyze the effect of decompression alone and combined decompression, fusion and internal fixation procedure for degenerative lumbar stenosis in elderly patients. METHODS We reviewed 168 lumbar stenosis patients treated using decompression alone or with combined procedures in the department of orthopaedics of Tianjin 4(th) Centre Hospital from October 2010 to January 2014. The cl...

The biophysical models that intend to predict the risk of decompression sickness after a change of pressure are not numerous. Few approaches focus in particular on joints as target tissues, with the aim to describe properly the mechanisms inducing pain. Nevertheless, for this type of decompression incidents, called articular bends, no model proved to fit the empirical results for a broad range ...

OBJECTIVE A meta-analysis of all published clinical trials comparing selective versus routine nasogastric decompression was performed in an attempt to evaluate the need for nasogastric decompression after elective laparotomy. BACKGROUND Many studies have suggested that routine nasogastric decompression is unnecessary after elective laparotomy and may be associated with an increased incidence ...

OBJECTIVE To compare horizontal eye positions between proptotic thyroid eye disease patients and normal individuals, and to examine positional changes after orbital decompression surgery in thyroid eye disease patients. METHODS The present case-controlled and retrospective comparative study included 78 proptotic thyroid eye disease patients who underwent bilateral orbital decompression surger...
