Filter by:The renal Doppler resistive index (RRI) is a noninvasive tool that has been used to assess renal perfusion in the intensive care unit (ICU) setting. It is associated with the occurrence of acute kidney injury (AKI). Many parameters have been described as influential on the values of renal RI. Red blood cell (RBC) transfusion were shown to be able to increase renal oxygenation in animal model, whereas crystalloid resuscitation did not. We sought to describe the different effect of crystalloids infusion and RBC transfusion on renal blood flow, as evaluated with doppler ultrasound
The purpose of this small randomized pilot study is to evaluate adherence to strict transfusion protocols in both the control and ANH group examining compliant and noncompliant transfusion rates and reasons for violation of the protocol if present. Data on transfusion requirements for both groups (with and without ANH) will be evaluated to determine sample size and feasibility of performing a larger study on ANH in our patient population. The ultimate purpose of a larger study would be to determine if acute normovolemic hemodilution results in a reduction in red blood cell units transfused in patients undergoing cardiac surgery involving cardiopulmonary bypass (CPB) and to carefully determine provider adherence to specific transfusion triggers for the administration of each unit of harvested and banked blood transfused. Secondary endpoints that will be evaluated in a larger study include any difference in the number of other blood products transfused including fresh frozen plasma, platelets, and cryoprecipitate as well as differences in coagulation status as measured by thromboelastography (TEG), INR/PTT, platelet count, and fibrinogen level, and ICU/hospital length of stay.
Sickle Cell Disease (SCD) is a serious inherited blood disorder affecting red blood cells. When oxygen levels drop the red cells become abnormally shaped and unable to move through the blood vessels easily. Blood and oxygen do not reach body organs, resulting in episodes of severe pain and other complications. Pregnant women with SCD have an increased risk of both sickle and pregnancy complications, including raised blood pressure. Their babies may grow more slowly in the womb, are more likely to be born early and need special care, and have a higher risk of dying. The only treatments currently available for women with SCD are Hydroxycarbamide (which cannot be used during pregnancy) and blood transfusion. Currently, blood transfusion is only used during pregnancy to treat emergency complications. It has been suggested that giving blood transfusions throughout pregnancy could improve outcomes for both mother and babies. In Serial Prophylactic Exchange Blood Transfusion (SPEBT), sickle blood is mechanically removed and simultaneously replaced with donor red cells. A trial is needed to assess SPEBT given every 6-10 weeks, starting before 18 weeks of pregnancy, compared to standard care. This trial will evaluate outcomes for women (e.g. hospital admission, frequency of crisis) and their infants (e.g. early delivery, birthweight). However, the feasibility of such a study needs to be assessed before embarking on a large multicentre trial. This study is therefore a feasibility study in which we will randomly allocate participants to have either SPEBT or standard care. The study will be carried out in multiple maternity units in England and last two years. The willingness of eligible women to join the study will be assessed, along with how many participants remain part of the study until the end and if participants find the intervention acceptable.
The evaluation uses ΔHb as an independent factor combined with artificial intelligence (AI) to predict its impact on the prognosis and blood transfusion of patients undergoing cardiac surgery, thereby guiding perioperative clinical blood use and improving patient prognosis.
According to the patient's blood management concept, this study intends to collect basic information, surgical data, blood transfusion related data and patient prognosis data of patients with pelvic fractures, and to construct a predictive model of intraoperative blood transfusion in patients with pelvic fractures by multiple linear regression analysis. To guide physicians use blood accurately during surgery. Prompt doctors to reduce blood transfusion dose and improve patient prognosis by stopping bleeding and blood recovery before surgery.
Based on the principle of patient blood management, this study aims to reduce the risk of blood transfusion in allogeneic liver transplantation patients, to ensure the safety of blood transfusion, and to provide new methods and basis for restrictive blood transfusion.
Primary aim is to evaluate the effect of blood transfusion on oxidant-antioxidant status in premature neonates. Secondary aim is to assess the effect of the age of transfused red blood cells on the biological markers of oxidative stress.
Since 1987, red blood cell (RBC) transfusions have been proposed as a potential risk factor for necrotizing enterocolitis (NEC), which is one of the most severe gastrointestinal complications of prematurity. Evidence from Doppler studies have shown a post-transfusion impairment of mesenteric blood flow in response to feeds, whereas NIRS studies have reported transient changes of splanchnic oxygenation after RBC transfusion; a possible role for these findings in increasing the risk for TANEC development has been hypothesized. The aim of this study is to evaluate SrSO2 patterns in response to enteral feeding before and after transfusion.
The objective of this study is to determine the effectiveness of a Proficiency Based Progression training programme, together with evidence based individual feedback for any residual errors, which has been specifically developed for healthcare professionals performing phlebotomy at Cork University Hospital at reducing blood sampling errors including Wrong Blood in Tube (WBIT). This will allow us to internationally address the universal problem of sample mislabeling and WBIT. A pilot project which consisted of PBP delivered to 46 interns commencing work in July 2017 has shown a 47% reduction in haematology errors and a 67% reduction in WBITs in the haematology department. However, the sample size was small to result in a statistically significant reduction in WBITs and the investigators are concerned that the results were undermined by the fact that SHOs were not using the method outlined by the metric and may have influenced the standard practice of interns. This study by training interns and SHOs will be better able to determine the influence of the training programme in reducing error rates.
Blood transfusion is very lengthy procedure and consumes a substantial time from patients and health care providers. On average, it may take most if not all the working day which leads to significant constrains on hospital bed utilization. It starts from pre-transfusion testing, clinical assessment, actual administration of blood and post-transfusion care. The main bulk of this procedure is usually related to administration of the blood which typically given over 3 hours (5ml/kg/hour), although there is no strong evidence to support that. Indeed, it has been accepted as standard of care to transfuse blood over short time as in emergency situations. OBJECTIVE: To determine the maximum tolerated blood transfusion rate that can be safely delivered in patient who required blood transfusion i.e. transfusing blood over short time. METHOD: This is a phase I, open label, nonrandomized, prospective and rate-finding study. A well-known dose escalation design called 3+3 design will be used to identify the maximum tolerated rate. To assure the safety of such procedure, blood transfusion rate will be escalated very slowly by 1 ml/kg/hour for each cohort until rate-limiting toxicities or maximum of 10ml/kg/hour.
