BACKGROUND During total hip arthroplasty (THA) drainage is used by most surgeons. However, the optimal drainage strategy remains controversial. The aim of this prospective cohort study was to determine the safety and efficacy of a four-hour drainage clamping technique in patients undergoing THA. MATERIAL AND METHODS There were 64 patients who underwent THA from March 2012 to December 2015 who w...
A Meta-Analysis of the Effect of Preoperative Biliary Stenting on Patients With Obstructive Jaundice
The goal of this study was to systematically review the effects of biliary stenting on postoperative morbidity and mortality of patients with obstructive jaundice. PubMed, Embase, Cochrane Library, and other relevant databases were searched by computer and manually for published and unpublished studies on the impact of preoperative biliary drainage on patients with obstructive jaundice from 200...
Soil saturated hydraulic conductivity (k) and effective porosity (f) are the most important parameters to simulate the processes associated with irrigation, drainage, hydrology, leaching and other agricultural and hydrological processes. Present methods to measure these parameters are often difficult, time consuming and costly. Therefore, a method which provides more accurate estimates of these...
Today, due to climate change, natural hazards and how to deal with them are among the most important concerns of researchers in environmental planning and crisis management. The purpose of this study is the assessment of the potential flood risk in Sarbaz drainage basin. For this purpose, the databases including elevation, slope, geological characteristics, soil characteristics, precipitation, ...
PURPOSE To assess the therapeutic value of two different drainage catheters in treating chronic subdural hematoma (CSDH). MATERIALS AND METHODS Two types of drainage catheters can be used to treat CSDH according to the position of holes in the catheter: open-type or closed-type catheter. In this retrospective study, 199 total patients with CSDH were reviewed according to catheter type. Among ...
Gravity drainage is one of the important recovery mechanisms in fractured carbonate and conventional reservoirs. It occurs due to density difference between the gas in fracture and the oil in matrix as well as in conventional tilted reservoirs. Oil phase will form films which are produced under gravity forces (film flow). Many gas injection experiments have been done on laboratory scales with d...
Introduction: The removal of the chest tube drainage is a painful experience for patients. Painless pain and patient's discomfort is associated with reduced chest dilatation, respiratory dysfunction with hypoxemia, increased sympathetic response to myocardial ischemia, and increased general response to tachycardia. The purpose of this study was to investigate the use of cold compresses before r...
l and drainage has been central to the development of North America since colonial times, with the first organized drainage efforts occurring as early as the 1600s (Evans et al. 1996). Drainage has been encouraged to improve public highways, reduce public health risks, promote increased crop yield and reduced yield variability, reduce surface runoff and erosion, and increase land value. Agricul...
