  • The effect of cardiopulmonary bypass on platelet count, platelet function, and bleeding time was studied in 60 patients. Platelet count was significantly reduced during and after cardiopulmonary bypass. Platelet function also had a reduced aggregation response to adenosine diphosphate. Bleeding time was prolonged to over 30 minutes during cardiopulmonary bypass and not returned to normal level until postbypass 1 hour. The amount of postoperative bleeding was proportional to the degree of decrease in platelet count and function, degree of decrease in platelet count and function. There was no significant correlation between duration of cardiopulmonary bypass and platelet count, platelet function, bleeding time, or amount of postoperative bleeding. Patients with cyanotic congenital heart disease showed a larger amount of postoperative bleeding than patients with acyanotic congenital heart disease [P<0.01], and this difference was due to the fact that platelet function was more significantly affected by cardiopulmonary bypass in cyanotic group. Patients using membrane oxygenator showed a less amount of postoperative bleeding than patients using bubble oxygenator [p<0.005] reflecting better preservation of platelet count and function by membrane oxygenator.

  • Background: Nasotracheal intubation for general anesthesia is preferred for oral and maxillofacial procedures because it provides improved access to the operative site. Fiberopic nasotracheal intubation is a useful technique when airway management seems difficult. But, intaoral bleeding is considered as the important factor that makes fiberopic nasotracheal intubation difficult. The purpose of our study was to elucidate the effect of laryngeal view and bleeding on intubation difficulty during fiberopic intubation. Methods: We studied 461 patients undergoing nasotracheal intubation with permission. Laryngeal view grades were examined with laryngoscope and were recorded. Then, intubation time and the amounts of bleeding were measured during fibroptic nasotracheal intubation under general anesthesia. Results: There was no significant difference between laryngeal view grade and intubation difficulty (P > 0.05). But severity of bleeding increased intubation difficulty (P < 0.05). Conclusions: In this study, the significant amounts of bleeding had an effect on intubation difficulty.

  • 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.

  • This paper describes the properties analysis of concrete using bleeding reduction agent. According to the results, the fluidity and the air content of fresh concrete with increase of bleeding reduction agent show little difference in compare with plain concrete which does not use bleeding reduction agent. The efficiency of bleeding reduction agent is confirmed because in variation of W/C and slump, the increase of bleeding reduction agent dosage reduces bleeding remarkably. And the compressive strength of hardened concrete does not show any differences with increase the dosage of bleeding reduction agent. Bleeding reduction agent does not have bad effect on the quality of concrete such as fluidity, air content and the strength of hardened concrete and so on, the dosage of it can reduce bleeding effectively.

  • Recently, practice education using virtual medical simulation has been applied to real clinical environment by enhancing the learning efficiency. Specially, in minimally invasive surgery, the necessity of virtual surgery medical simulation has been increased. Realistic bleeding animation, which represents bleeding special effects frequently occurred in virtual medical simulation environment, has not been proposed yet. In this paper, we propose realistic real-time bleeding animation. For bleeding simulation, proposed method calculates main and effective bleeding regions along the main bleeding direction vector to represent naturalistic bleeding effect. In addition, for bleeding rendering, proposed method uses sigmoid function to impose weights of vertex opacities for the smooth opacity change so that the results of bleeding animation is realistic. Proposed method improves the sense of the real and absorption in virtual surgery medical simulation so that the education efficiency of doctors and students using medical simulation can be enhanced.

  • Purpose : Preservation of the periodontal health of the treated patient requires supportive periodontal therapy for the elimination of periodontal disease. After Phase I therapy is completed, patients are placed on a schedule of periodic recall visits for maintenance care to prevent recurrence of the disease. The amount of tooth loss would be the most relevant criterion in an evaluation of the effect of periodontal treatment, but this would require studies with extremely long follow-up periods. Thus the most commonly used outcome criteria in clinical research have been clinical attachment level change, reduction of pocket depth and bleeding frequency. The purpose of this case study is to identify the effect of supportive periodontal therapy after periodontal flap surgery. Materials & Methods : Following routine hygienic phase of treatment, patients with chronic periodontitis received surgical periodontal treatment. Bleeding on probing, pocket depth and clinical attachment level were measured at baseline, pre-operation and 1 year follow up. All procedures were performed by one operator. Results : One year a total of 28 patients (58sites) to recheck remained, when conducted maintenance program after periodontal flap surgery was observed reduction of bleeding frequency, pocket depth and improvement of clinical attachment level. Conclusion : The results from this study indicate that supportive periodontal therapy after periodontal flap surgery is effective for reduction of bleeding frequency, pocket depth and gain of clinical attachment level.
