Fresh dry plasma (FDP) is a lyophilized form of fresh frozen plasma (FFP) which can be stored at 4 degrees C for one year. One bottle of FDP is prepared from 220 ml of FFP and contains FVIII: C 0.75 +/- 0.3 U/ml (mean +/- 1 SD). This study describes the clinical and laboratory response in 7 severe and 4 moderate hemophilia A patients. The age ranged from 7-17 years (mean +/- SD = 11.7 +/- 2.9 years). Either 12.4 ml/kg. FDP or 12.2 ml/kg FFP was transfused to the patients when they had bleeding episodes such as hemarthrosis, hematoma. 16 episodes of FDP and 12 episodes of FFP transfusion were studied. The bleeding could be effectively controlled by FDP or FFP except one patient who had physical therapy at 8 hours post FDP transfusion. The increment of FVIII:C was 14.1 +/- 5.3% at 30 minutes after FDP transfusion and 12.1 +/- 3.7% at 30 minutes after FFP transfusion. The recovery rate was 83.2 +/- 32.6% in FDP and 65.3 +/- 22.7% in FFP transfusion. The FVIII:C was decreased to 78.9 +/- 12.3%, 55.6 +/- 13% and 16.3% of the initial level at 2, 8, 24 hours after FDP transfusion respectively which were not statistically significantly different from FFP transfusion. No serious complication was found. FDP will replace FFP for the treatment of coagulation disorders such as hemophilia A. It is an useful alternative therapy which can be provided to the hemophiliac patients in the rural area in developing countries.

Clinical Outcomes with High- versus Low-Dose Tranexamic Acid Infusion in Patients Undergoing Cardiac Surgery: A Systematic Review and Meta-Analysis.

Department of Medicine, MedStar Health, Baltimore, Maryland, United States.
Objectives: Antifibrinolytics, such as tranexamic acid (TXA), are widely used in cardiac surgery to reduce bleeding risks; however, the optimal dosage for TXA infusion remains a subject of debate. Hence, this study aims to evaluate the safety and efficacy of high-dose compared with low-dose TXA infusion in cardiac surgery patients.
Methods: PubMed, SCOPUS, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched until June 10, 2023, for studies assessing efficacy outcomes (e.
Successful Laparoscopic Sleeve Gastrectomy in a Patient With Rare Congenital Factor VII Deficiency: A Case Report and Management Strategy.

Congenital factor VII (FVII) deficiency is a rare coagulation disorder that increases the risk of bleeding complications during surgery. Although laparoscopic sleeve gastrectomy (LSG) is the most common metabolic bariatric surgery (MBS), it is rarely performed in patients with congenital coagulation disorders such as FVII deficiency, due to the high risk of intraoperative and postoperative bleeding. We report the case of a 57-year-old female with class II obesity (BMI 37.

Introduction: Massive hemorrhage calls for massive transfusions (MTs) to maintain adequate hemostasis. Massive transfusion protocols (MTPs) are the appropriate treatment strategy for such patients replacing conventional use of crystalloids. These help in standardizing and optimizing the delivery of blood components in a well-balanced ratio.

From the Department of Anesthesiology and Perioperative Medicine, Mayo Clinic, Phoenix, Arizona.
Background: During orthotopic liver transplantation, allograft reperfusion is a dynamic point in the operation and often requires vasoactive medications and blood transfusions. Normothermic machine perfusion (NMP) of liver allografts has emerged to increase the number of transplantable organs and may have utility during donation after circulatory death (DCD) liver transplantation in reducing transfusion burden and vasoactive medication requirements.
Methods: This is a single-center retrospective study involving 226 DCD liver transplant recipients who received an allograft transported with NMP (DCD-NMP group) or with static cold storage (DCD-SCS group).

Objective(s): This study was designed to assess the relative association between adjunctive fresh frozen plasma (FFP) or adjunctive cryoprecipitate and morbidity and mortality in cardiac surgery patients receiving platelets for perioperative bleeding.
Design: Retrospective cohort study using inverse probability of treatment weighting with entropy balancing.
Setting: Multi-institutional study of 58 centers using the Australian and New Zealand Society of Cardiac and Thoracic Surgeons National Cardiac Surgery Database from January 1, 2005, to December 31, 2021.
