Haemodilution induces a hypercoagulable state 总被引:10,自引:3,他引:7
It has been suggested that haemodilution with saline may increase whole
blood coagulation. This study was conducted in two parts. First, we
investigated the effect of in vitro dilution of blood with saline on whole
blood coagulation as measured by the thrombelastogram (TEG). Blood (4 ml)
was diluted with 0.9% saline 1 ml and coagulation compared with that of an
undiluted control specimen obtained concurrently from the same subject. In
the second part, the study was repeated using a modified gelatin colloidal
solution (Haemaccel) as the diluent. The r time, k time and r + k time were
decreased relative to control in both diluent groups. The alpha angles were
increased compared with control in both groups while maximum amplitude was
unchanged in the Haemaccel diluted group. We conclude that haemodilution
per se increases the coagulability of whole blood in vitro, but that saline
haemodilution has a more marked effect on final clot strength.

Repair of large midline incisional hernias with polypropylene mesh: Comparison of three operative techniques 总被引:9,自引:0,他引:9
de Vries Reilingh TS van Geldere D Langenhorst BLAM de Jong D van der Wilt GJ van Goor H Bleichrodt RP 《Hernia》2004,8(1):56-59
Polypropylene mesh is widely used for the reconstruction of incisional hernias that cannot be closed primarily. Several techniques have been advocated to implant the mesh. The objective of this study was to evaluate, retrospectively, early and late results of three different techniques, onlay, inlay, and underlay. The records of 53 consecutive patients with a large midline incisional hernia — 25 women and 28 men, mean age 60.4 (range 28–94) — were reviewed. Polypropylene mesh was implanted using the onlay technique in 13 patients, inlay in 23 patients, and underlay in 17 patients. Either the greater omentum or a polyglactin mesh was interponated between the mesh and the viscera. The records of these 53 patients were reviewed with respect to: size and cause of the hernia, pre- and postoperative mortality and morbidity, with special attention to wound complications. Patients were invited to attend the outpatient clinic at least 12 months after implantation of the mesh for physical examination of the abdominal wall. Postoperative complications occurred in 14 (26.4%) patients. The onlay technique had significantly more complications, as compared to both other techniques. Reherniation occurred in 15 (28.3%) patients. The reherniation rate of the inlay technique was significantly higher than after the underlay technique (44% vs 12%, P=0.03) and tended to be higher than the onlay technique (44% vs 23%, P=0.22). Repair of large midline incisional hernias with the use of a polypropylene mesh carries a high risk of complications and has a high reherniation rate. The underlay technique seems to be the better technique. 相似文献

Over an 8-year period (1982-1989) 43 patients with subacute and chronic extradural haematomas were treated. The clinical picture of the patients, computed tomography (CT) as well as operative findings and prognosis were evaluated. The radiological picture as seen on CT was correlated with the time interval elapsing between initial trauma and surgery. Operative findings are discussed and the terms 'subacute' and 'chronic' are defined. 相似文献

Widespread epiphyseal stippling was demonstrated radiologically during the early months of life in 7 children with acrodysostosis. This finding, which does not seem to have been previously documented in this disorder, is important in the differential diagnosis. 相似文献

A 20-year-old woman with Beckwith-Wiedemann syndrome (BWS) was ultrasonographically appraised at intervals during her pregnancy. Unequivocal evidence for a diagnosis of BWS was obtained in the fetus and this was confirmed postnatally. Early ultrasound diagnosis enabled appropriate genetic counselling to be given; neonatal complications, such as hypoglycaemic episodes, were prevented. 相似文献

An anomalous pulmonary vein draining into the subdiaphragmatic inferior vena cava was initially demonstrated on computed tomographic (CT) scans. The diagnosis of scimitar syndrome was confirmed with digital subtraction angiography. In retrospect, the anomalous vein and dextroposition of the heart were shown on chest radiographs. 相似文献

Alpha-glucosidase activity and sperm motility 总被引:2,自引:0,他引:2
We correlated the activity of alpha-glucosidase in seminal plasma with the motility and differential motility of sperm. Significant positive correlations were found between the alpha-glucosidase activity and both motility and the percentage sperm with good forward progression. This supports the use of alpha-glucosidase in semen as a marker of epididymal function and specifically of the development of motility. 相似文献
