conclusions both dexmedetomidine and esmolol can be used as agents to control hypotension in patients undergoing lumbar spine decompression and fixation surgery; the dexmedetomidine group, however, was associated with better intraoperative hemodynamic stability and reduced intraoperative analgesic and volatile anaesthetic requirement. results the study results showed that dexmedetomidine had lo...

prior animal models have shown that rats sustaining 3-second immediate spinal cord compression had significantly better functional recovery and smaller lesion volumes than rats subjected to compression times of 1 hour, 6 hours, 3 weeks, and 10 weeks after spinal cord injury. we compare locomotor rating scales and spinal cord histopathology after 3 seconds and 10 minute compression times. . ten ...

Emphysematous bullae are closed air containing spaces in lung parenchyma that may severely compromise lung function in patients of chronic obstructive pulmonary disease (COPD). We describe a simple and minimally invasive procedure to decompress a large emphysematous bullae in a patient with advanced COPD and high surgical risk. Transthoracic decompression of the bulla was accomplished under sho...

Deep sea divers, aviators and astronauts are at risk of decompression sickness when the ambient pressure reductions exceed a critical threshold. Venous bubbles associated with decompression sickness have the potential to react with the vascular membrane and adjacent blood products, eliciting an inflammatory cascade. Preventive measures usually involve careful decompression procedures to avoid o...

BACKGROUND Deep decompression stops are increasingly common in recreational technical diving. Concerns exist that they shift decompression stress back into slower tissues. A diver recorded an exceptional exposure dive, with deeps stops, on a commercially available dive computer. MATERIAL AND METHODS Using the R package SCUBA tissue inert gas pressures in 17 Bühlmann (ZH-L16A) compartments wer...

Decompression stress can cause endothelial injury, leading to systematic inflammation and prothrombotic phenomena. Our previous work found that endothelial injury following decompression correlated positively with bubble formation. This study aimed to investigate the time course of endothelial injury and the relationship with bubble amounts. Rats were subjected to a simulated air dive to 7 ATA ...

PURPOSE To report the outcomes of continuous decompression using a cannulated ceramic pin for simple bone cysts (SBCs). METHODS Seven boys and 3 girls aged 7 to 16 (mean, 11) years with SBCs underwent curettage and continuous decompression using a cannulated ceramic pin. The pin was made of hydroxyapatite and tricalcium phosphate. The clinical course, radiological findings, and complications ...

BACKGROUND Bifrontal contusion is a common clinical brain injury. In the early stage, it is often mild, but it progresses rapidly and frequently worsens suddenly. This condition can become life threatening and therefore requires surgery. Conventional decompression craniectomy is the commonly used treatment method. In this study, the effect of intracranial pressure (ICP) monitored stepwise intra...

BACKGROUND/AIM To investigate the effects of conservative therapy applied before arthroscopic subacromial decompression on the clinical outcome in patients with stage 2 shoulder impingement syndrome. MATERIALS AND METHODS Sixty-eight patients having stage 2 shoulder impingement syndrome and treated with arthroscopic subacromial decompression were included in the study. We divided these patien...
