  • Background The aim of this study was to analyze the clinical results of minimal single palmar-incision carpal tunnel release without a tourniquet. Methods We reviewed the medical records of 75 patients (90 cases of carpal tunnel syndrome) who underwent minimal single-palmar incision carpal tunnel release without a tourniquet from June 2010 to January 2018. Ten patients had a bleeding tendency. We compared the preoperative and postoperative Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) scores. We also analyzed outcomes and complications according to the presence of a bleeding tendency. Results In all cases, there was a complete disappearance or marked improvement in symptoms within 6 months, with no recurrence. The postoperative BCTQ score showed a significant improvement compared to the preoperative score, and no statistically significant difference in BCTQ scores was detected according to the presence of a bleeding tendency. Conclusions Carpal tunnel release without a tourniquet using a minimal single palmar incision is effective and reliable. This technique prevents unnecessary pain associated with the tourniquet and is especially helpful in patients with a bleeding tendency or those treated with hemodialysis.

  • This paper investigates the influence of fine aggregates on bleeding of concrete. According to test results, as water content decreases, crushed sand content increases, fluidity shows decline tendency. As for aggregates kinds, concrete using sea sand shows most fluidity loss among the tested results. Compressive strength gains highly when crushed sand is used. As for bleeding of concrete, bleeding shows decline tendency because of increasing in powder content and filling effect of voids. Bleeding amount is in a decreasing order of magnitude for concretes made with the following aggregates: sea sand, river sand, and crushed sand. Accordingly, crushed sand mixed with river sand and sea sand with certain proportion enable to reduce bleeding and enhance strength.

  • This paper investigates the influences of water content and viscosity agent on the bleeding of concrete. According to test results, fluidity shows decline tendency as water content decreases, and dosage of viscosity agent increases. PEO viscosity agent does not affect the air contents while, MC viscosity agent causes air loss. As for bleeding, bleeding decreases with decrease of water content. As dosage of viscosity agent increase, bleeding decreases, regardless of viscosity kinds. It is thought that viscosity agents have the favorable effect of reducing bleeding, if fluidity and air loss are improved.

  • Clinical findings in neonates and infants with cholestasis characteristically include prolonged jaundice, acholic stool, pruritus and failure to thrive. We report two cases of cholestasis presenting with spontaneous bleeding due to vitamin K deficiency. Laboratory studies on admission revealed moderate liver dysfunction and a bleeding tendency due to vitamin K deficiency. After administration of vitamin K, the bleeding tendency disappeared. Vitamin K deficiency was resulting from a combination of cholestasis-induced fat malabsorption and low vitamin K supplementation due to breast-milk feeding. Cholestasis should be considered in neonate and infant with a bleeding tendency.

  • Antiplatelet agent is administered to the patients who have ischemic heart disease, transient cerebral infarction, as well as hypertension, etc. Antiplatelet agent prevents thromboembolism by inhibition of platelet aggregation by various mechanism. Due to that reason, patient who administered antiplatelet agent has bleeding tendency. Surgeon does not want to make a complication by bleeding during and after operation, and want to stop taking antiplatelet agent. However, It is very dangerous for the patient to stop antiplatelet agent. Local bleeding as a complication after operation is considered minor one, whereas thromboembolism is life threatening serious complication. Most dental intervention can be performed without withdrawal of antiplatelet agent. Dental intervention should be limited area, and surgeon should do active bleeding control.

  • During the 5 years period(93-197) of Seoul racecourse Thoroughbred racing, 2i963 holies took an active part in Seoul Racecourse and 61,181 horses entered the racing.400 horses(305 : 1 time, 76 :2 times, 19 :3 times, total : 514 cases) had bled(EIPH) from their nostils after their races. Incidence of bleeding horses from the 21963 racehorses was 13.5%, and incidence of bleeding cases from the 61,181 horses was 0.84%. The average racing frequence (1.05 times/1 month) of bleeders was more than that(0.8 times/1 month) of total race-horses. There was tendency to higher incidence of bleeding at older in age, female in sex, England/ Ireland horses in origin, higher grade in performances heavier in body weight increased, larger in weight to be carried, mid or longer in racing distance, handicap race, spring in season. Relationship did not exist between bleeding and respiratory disease. These results suggested that frequent entering into the race should be controlled. And body weight regulation with conditioning is recommended far reducing incidence of EIPH. It is supposed to prevent bleeding that decrescent performance horses should not be entering long distance or handicap race.

  • Postoperative autotransfusion is known as an effective method for blood conservation. We tried to examine whether the autotransfusion of shed mediastinal blood in patients with unstable angina would be valuable for reducing postoperative homologous transfusion by observing the hourly tendency of bleeding and transfusion. Between August and October, 1997, 26 patients with unstable angina underwent coronary arterial bypass surgery by a single surgeon at Asan Medical Center. In retrospective analysis, we found 90% of the patients received homologous transfusions and 85% of them were in the intensive care unit at the same day after operation. In many patients, the cause of transfusion was not anemia but volume replacement. Mean bleeding through the chest tubes was 340 cc for the first 5 hours and 69%(18 pts) showed more than 200 cc of bleeding, the amount generally considered as a initiating point for autotransfusion. Despite the adoption of multiple methods for blood conservation, 90% of the patients needed homologous transfusion. Moreover, many of them had received unnecessary transfusions. We conclude that some kind of blood for transfusion is needed during the immediate postoperative period, and the adoption of postoperative autotransfusion may help in reducing homologous transfusion.

  • The influences of the acute hemorrhage on the intestinal functions were studied in the rabbits subjected to acute bleeding, amounting 1.5-2% of the body weight. The motility and the absorptive capacity of the ileum were compared before and after the bleeding. Transfusion of shed blood was also performed in order to see whether the deteriorations were reversible or not. The tension developed in the direction of the longitudinal axis of the ileum was recorded through an appropriate transducer, and the frequency of the rhythmic contraction was counted throughout the procedure. Test solution, 10ml in amount, was placed in the loop of the ileum, and the samples were drawn at zero time and at 20 minutes. Triplicated procedures were repeated on the same loop;namely, before and after bleeding and after transfusion. The test solution was composed of 200 mg% urea, 218 mEq/l of NaCl and 150 mg% of polyethylene glycol (PEG) No. 4,000 in distilled water. The latter substance was used as a marker substance for the volume change of the loop. The results obtained were as follows; 1. The motility of the ileum suffered little effects by acute hemorrhage. However, minor fluctuations were seen in the frequency of the rhythm, showing a slight tendency of decreasing rhythmicity, and it was reversed by transfusion. 2. Diminution of absorptive capacity of urea was noticed in acute hemorrhage and it was interpreted as the consequence of the secondary effect of the retardation of the active transport mechanism governing the sodium transport 3. Absorption rate of the sodium ion was dropped in the hemorrhage, suggesting the indispensable need of the blood supply. 4. Osmolarity of the luminal fluid remained higher in the case of acute hemorrhage. 5. There was a tendency of retaining more fluid in the intestinal lumen in acute hemorrhage, comparing with that observed prior to the bleeding. 6. The deteriorations in the absorptive capacity were restored by transfusion of shed blood.

  • CO in the reformed gas for proton exchange membrane fuel cell(PEMFC) has a strong tendency to adsorb on the surface of the catalyst and thus to block the sites that hydrogen needs for reactions. Even part per million levels of CO can cause serious poisoning. This CO poisoning can overcome to bleed trace amounts of air into the anode. In this study, we indicated the alteration of stack performance in various CO concentration and then bled a small amount of air. The performance of stack was reduced by increasing CO amount, and recovered by air bleeding. But the air-bleeding have an impact on performance of anode should be further explored.
