OBJECTIVE To determine the incidence of residual pneumothorax after video-assisted thoracic sympathectomy, with and without postoperative pleural drainage, and to evaluate the possible influence of this type of pneumothorax on postoperative pain within the first 28 postoperative days. METHODS All patients presenting symptoms consistent with primary palmoplantar hyperhidrosis and treated at th...
Thermal recovery involves well-known processes such as steam injection (cyclic steam stimulation, steam drive, and steam-assisted gravity drainage), in situ combustion, and a more recent technique that consists of heating the reservoir with electrical energy. When high frequency is used for heating, it is called electromagnetic (EM) heating. The applications of EM heating for heavy-oil reservoi...
The Tokyo Guidelines of 2007 (TG07) described the techniques and recommendations of biliary decompression in patients with acute cholangitis. TG07 recommended that endoscopic transpapillary biliary drainage should be selected as a first-choice therapy for acute cholangitis because it is associated with a low mortality rate and shorter duration of hospitalization. However, TG07 did not include t...
Recently, in a previous study, we experimentally showed the existence of an optimal injected steam mass flow rate, per unit length, ϕopt, which produces maximal recovery condensate preformed chamber with elliptical cross section horizontal semi-major axis. Mutatis mutandis, this work, present experimental studies chambers: one and other circular. In both cases, also found unique values. These c...
Single catheter gravity drainage of the right atrium or right ventricle during total cardiac bypass.
The currently employed cannulations preparatory to establishing cardiac bypass with the aid of a pump-oxygenator, include isolation of the superior and inferior vena cavae over tapes and the insertion of catheters into each of these vessels. t At the onset of bypass the caval tapes are tightened around the indwelling catheters and venous drainage is effected by suction applied to the venous lin...
Fractured carbonate reservoirs account for 25% of world’s total oil resources and for 90% of Iranian oil reserves. Since calcite and dolomite minerals are oil wet, gas oil gravity drainage (GOGD) is known as the most influencing production mechanism. The most important issue within gas injection into fractured media is the channeling problem which makes the efficiency of gas injection process e...
Naturally fractured carbonate reservoirs (NFCRs) comprise the majority of the oil and gas reservoirs around the Persian Gulf. Many of these reservoirs have a long history of exploitation, but vast amounts of oil remain in place. A major redevelopment process for light oil based NFRs will likely be the use of horizontal wells combined with gravity drainage at constant pressure based on voidage...
