BACKGROUND: Percutaneous nephrolithotomy (PCNL) is the standard of care for the treatment of renal stones >2cm and staghorn calculi. This minimally invasive procedure however has intraoperative hemorrhage as one of its most dreaded complications. OBJECTIVE: To analyze the rate of hemorrhage and transfusion requirements among patients undergoing either PCNL or open stone surgery (OSS). METHODS: This was a retrospective study conducted at the National Kidney and Transplant Institute Medical Records Department. Data were collected for the period of January 2018 to December 2019. RESULTS: One hundred forty cases were included, 102 patients in the PCNL group and 38 in the OSS. The mean age 50.84±11.89 vs. 50.50±10.09 with male to female ratio of 1.2:1 for PCNL and open surgery, respectively. The most common comorbidity was hypertension (89, 63.6%). As regards stone size, majority had >4 cm stone size (61; 43.9%). In PCNL, there was no significant change noted in the hemoglobin (14.69±13.3 vs 12.03±1.91, p= 0.099) as compared to OSS, where there was significant decline (12.77±2.64 vs. 11.06±2.52; = .000. The number of packed red cell units for transfusion was also significantly higher in OSS compared to PCNL group (.526±.861 vs. 159±.502, p .020.) CONCLUSION In the treatment of staghorn calculi, PCNL incurs less blood loss and lower transfusion requirements compared to open stone surgery.

Cardiac surgery is frequently associated with an excessive perioperative blood loss requiring transfusion of blood products. Various point-of-care(POC) assessments for coagulation and platelet function allow an appropriate and, targeted therapy and reduce blood loss and transfusion requirements. In particular, a quick evaluation of platelet and coagulation defects with new POC devices can optimize the administration of pharmacological and transfusion-based therapy in cardiac surgery. The main advantages of POC tests are shorter time delay, assessment in whole blood and patient's temperature, potential to measure entire clotting process and to include information of platelet function. A transfusion algorithm using POC tests showed effectiveness in reducing intraoperative bleeding and transfusion requirements. Standardized procedure, strict quality control and trained personnel are highly recommended for optimal accuracy and performance of POC tests.

Background: Cardiac surgery with cardiopulmonary bypass (CPB) can cause haemostatic abnormalities that increase the risk of postoperative hemorrhage. Objectives: (1) To study changes of coagulation in cardiac patients undergoing surgery with CPB. (2) To research the relationship between duration of cardiopulmonary bypass, coagulation tests and postoperative hemorrhage complications. Subjects and methods: A cross sectional descriptive study was carried out on 252 patients (105 women, 147 men) undergoing cardiac surgery with CPB due to congenital heart disease and acquired heart disease at Viet Duc Hospital from December 2005 to August 2006. Results: After surgery, 54 patients had to transfuse the blood products, accounting for 21.4% rate. 21 cases had abnormal bleeding (8.3%). 12 patients assigned to re-operate due to bleeding (4.8%). There was an inverse correlation between platelet counts after surgery with duration of CPB and duration of aortic clamping. Relationship between rate of prothrombin, APTT, fibrinogen after surgery and duration of CPB and duration of aortic clamping was not seen. Duration of CPB prolonging over 120 minutes related to postoperative hemorrhage complication (OR=2.69 (p<0.5)). Reduced platelet count increased the risk of postoperative hemorrhage but not statistically significant (OR=1.36; p>0.05). Prothrombin ratio of less than 50% associated with the risk of postoperative hemorrhage (OR=4.83; p<0.01). Conclusion: The routine coagulation tests can help monitor clotting in patients after cardiac surgery

We have 3 more cases of experiences of massive transfusion undergoing hepatobiliary surgery above 20 units of whole blood, packed RBCs, FFP or cryoprecipitate under thrombelastographic guidance and monitoring intraoperatively. One of them had been transfused with 98 units of whole blood and 16 units of PRBC during a couple of times operation without any post-massive transfused pulmonary complications. TEG was originally developed by Hartert in 1948 but its clinical use has been limited. Recently as increases of severe and persistent coagulopathy that accompanies end-stage liver diseases and leads to massive intraoperatve bleeding, minute-to-minute monitoring of the coagulation system is mandatory for successful completion of surgery and for patient survival. Under the condition of our clinical experiences TEG appears to be a very effective method of monitoring blood coagulation. First, blood coagulabilty can be observed rapidly and simply in acute clinical situations within 30 minutes. Second, it assesses the quality of blood clot including the influence of cellular and humoral elements and pathologic conditions. The last, under the reliable guidance of TEG we could facilitate the segmental blood transfusion rather than using whole blood intraoperatively and it is to be a moment of the development of PRBC transfusion set by Kim et al.

BACKGROUND: Blood transfusion is often performed to support successful brain surgery. In this study, we looked at two groups of surgery patients to analyze the transfusion requirements for patients undergoing brain surgery in our hospital. Group A patients received elective surgery, whereby blood products were prepared in advance, and Group B patients required emergency surgery which is often accompanied massive bleeding, and therefore adequate transfusion blood may not be available in advance. METHODS: During a one year period, patients who received brain surgery were classified as requiring either elective (Group A) or emergency (Group B) surgery. In each group, operation time and blood transfusion requirements were compared. RESULTS: Of the 35 total patients included in this study, 14 cases were Group A and 21 cases were group B. Average operation time was 4 hours and 13 minutes (253 minutes), and 2 hours and 50 minutes (170 minutes), respectively for Groups A and B. Red Blood Cell (RBC) transfusion was conducted in more than 90% of all patients. Average volume of RBC transfusion per operation was 2.5 units (Group A) and 3.1 units (Group B). Fresh frozen plasma (FFP) was transfused in 21% of Group A patients and in 38% of Group B patients. Platelet Concentrate (PC) was transfused in 19% of Group B patients, only. CONCLUSION: FFP and PC were more frequently transfused in patients who received emergency surgery than those who received elective surgery. Preparation of, not only RBC, but FFP and PC is required for emergency brain surgery. Therefore, efforts to retain adequate amounts of blood are needed to support emergency brain surgery.

INTRODUCTION: Trauma-induced coagulopathy (TIC) is a form of coagulopathy unique to trauma patients and is associated with increased mortality. The complexity and incomplete understanding of TIC have resulted in controversies regarding optimum management. This review aims to summarise the pathophysiology of TIC and appraise established and emerging advances in the management of TIC. METHODS: This narrative review is based on a literature search (MEDLINE database) completed in October 2020. Search terms used were "trauma induced coagulopathy", "coagulopathy of trauma", "trauma induced coagulopathy pathophysiology", "massive transfusion trauma induced coagulopathy", "viscoelastic assay trauma induced coagulopathy", "goal directed trauma induced coagulopathy and "fibrinogen trauma induced coagulopathy'. RESULTS: TIC is not a uniform phenotype but a spectrum ranging from thrombotic to bleeding phenotypes. Evidence for the management of TIC with tranexamic acid, massive transfusion protocols, viscoelastic haemostatic assays (VHAs), and coagulation factor and fibrinogen concentrates were evaluated. Although most trauma centres utilise fixed-ratio massive transfusion protocols, the "ideal" transfusion ratio of blood to blood products is still debated. While more centres are using VHAs to guide blood product replacement, there is no agreed VHA-based transfusion strategy. The use of VHA to quantify the functional contributions of individual components of coagulation may permit targeted treatment of TIC but remains controversial. CONCLUSION A greater understanding of TIC, advances in point-of-care coagulation testing, and availability of coagulation factors and fibrinogen concentrates allows clinicians to employ a more goal-directed approach. Still, hospitals need to tailor their approaches according to available resources, provide training and establish local guidelines.

In order to find out possible causes and measures for prevention of intracerebral hemorrhage remote from the site of cerebral aneurysm surgery, the authors analyzed five patients who developed such a complication following aneurysm surgery among 720 surgical cases of cerebral aneurysm. The aneurysm sites were posterior communicating artery(Pcom) in two cases, anterior communicating artery(Acom) in two, and Acom and middle cerebral artery(MMCA) in one. The hemorrhages in three cases occurred in the cerebellum. One in the contralateral hemisphere and one in the ipsilateral hemisphere to the operation site. All hemorrhages except one occurred vasospasm preoperatively. Fluctuation of blood pressure with sudden elevation to high level was noticed in three cases preoperatively and in all cases postoperatively. We conclude that sudden elevation of blood pressure during the remission stage of vasospasm seems to be possible cause for remote hemorrhage. To prevent this complication, we recommend meticulous control of blood pressure during surgery and in the postoperative period, especially in cases that showed fluctuation of blood pressure preoperatively.

Autotransfusion has been known to have many benefits in patients who might have anticipated or unanticipated hemorrhage during elective or emergency surgical procedures. Twenty-nine patients with intracranial aneurysms with subarachnoid hemorrhage were enrolled in this study. Sixteen aneurismal patients were randomly selected for autotransfusion group, whose hematocrit value ranged between 21 to 39% after aspiration of mean arterial blood volume of 850 ml. For auto-transfusion, and 13 patients were given only homologous banked glood during surgical operation as control group. During surgical operation for direct clipping on aneurysmal neck in autotransfusion group, autotransfusion was applied by the method of perioperative blood collection and acute hemodilution of 30% hematocrit value. In 13 control aneurysmal patients who needed homologous banked blood during surgical operation to maintain normal blood pressure and intravascular blood volume, average mean volume of banked blood reguired was 1104 ml. In 16 aneurysmal autotransfusion group, it was only 438 ml of banked blood, and furthermore in 4 patients among them, homologous banked blood was not needed at all.

blood-born infection like AIDS via transfusion, nowadays an autologous blood transfusion is interesting to us. We made a comparative study of an amount of blood loss & transfusion using hemoglobin value after classifying the orthognathic surgeries from Feb. '97 to Mar. '98 in single-jaw and double-jaw surgery. And we intended to set a standard against of a routine preoperative cross-matching deciding the amount of predictive homologous blood transfusion according to operative method. Simultaneously, we studied the realization & effectiveness of autologous blood transfusion with some cases, so would like to present. RESULTS: 1. Single-jaw operation can be performed without blood transfusion or with homologous blood transfusion through only blood typing & screening. 2. We commonly transfuse two units of blood with double-jaw operation and an autologous blood transfusion has much more advantage than an homologous blood transfusion. 3. We can reduce charge associated with blood transfusion through precisely preoperative evaluation of patients and proper type of blood transfusion.]]>
