The study is designed to determine whether hemorrhage within the injured spinal cord is influenced by mean arterial pressure (MAP) augmentation with vasopressors and by venous thromboembolism (VTE) prophylaxis with anticoagulants in the first two weeks following a traumatic spinal cord injury (tSCI).
Cerebral amyloid angiopathy-related intracerebral (CAAH) hemorrhage is second factor of primary intracerebral hemorrhage. However, no effective prevention and treatment strategies have been established. Remote ischemic conditioning is a neuroprotective strategy. In animal studies，RIC is efficiency in accelerating the absorption of hematoma. Therefore, the investigators plan to carry out this research to evaluate the safety and efficacy of RIC in patients with CAA related ICH.
Around 230 million major procedures are performed worldwide each year. Postoperative complications after major surgery, especially in solid organ transplants, are associated with a significant increase in costs and mortality. Major bleeding episodes in major surgeries such as liver transplantation are related to a significant impact on morbidity and mortality. In this multicenter study, we aimed to compare the efficacy of tranexamic acid when compared to placebo, administered after anesthetic induction and in continuous infusion during the procedure, on the rate of intraoperative bleeding in adult patients undergoing liver transplantation. Considering its mechanism of action and its pharmacological and clinical properties, we expect to observe a significant reduction in the bleeding rate and in the need for blood components in the perioperative period of adult patients undergoing orthotopic liver transplantation. In this study, only adult ASA III to IV patients (18 to 70 years old), scheduled for orthotopic liver transplantation at the Hospital de Clínicas de Porto Alegre, Santa Casa de Porto Alegre and at the Hospital das Clínicas of the University of Sao Paulo will be included. Exclusion criteria consider patients with a history of acute arterial thrombosis or venous thromboembolism (<1 month), patients with a history of known thrombophilia, Budd-Chiari syndrome, primary biliary cholangitis, primary sclerosing cholangitis, patients with reduced left ventricular function ( ejection fraction <40%), pulmonary hypertension, preoperative pulmonary edema, or severe preoperative hemodynamic changes requiring the use of vasoactive drugs, planned use of tranexamic acid systemically during surgery, hypersensitivity or known allergy to acid tranexamic, history of seizure disorder, patients who have recently suffered a stroke or myocardial infarction (<1 month), patients with subarachnoid hemorrhage in the last 30 days and patients previously undergoing cranial neurosurgery. Major bleeding in this study will be defined as bleeding that results in hemoglobin ≤ 8.0 g / dL and the patient receiving a transfusion of ≥ 1 unit of red blood cells; results in a drop in hemoglobin ≥ 4.0 g / dL and the patient receives a transfusion of ≥ 1 unit of red blood cells; results in the patient receiving a transfusion of ≥ 4 units of red blood cells over a 24-hour period; or bleeding leading to surgical reintervention.
306 patients will be divided randomly in to 2 GROUPS: - control group: 153 patients will receive Oxytocin 10 IU I.V shot administered at the time of delivery of the anterior shoulder of the baby for both groups in prevention of postpartum haemorrhage,followed by active management of the third stage of labor by administration of oxytocin 5 IU units IM and waiting for signs of placental separation then controlled cord traction (CCT) to the umbilical cord while applying simultaneous counter-pressure to the uterus, through the abdomen(Brandt Andrews maneuver) - study group:156 patients received Oxytocin 10 IU I.V shot at the time of delivery of the of the anterior shoulder of the baby according to the WHO recommendation .Then oxytocin is stopped and cervical traction (Amr maneuver )is applied. In the maneuver,sustained traction downward and posteriorly was applied to anterior and posterior lips of the cervix using ovum forceps for approximately 90 seconds. The traction should be adequate to allow the cervix to reach the vaginal introitus. Meanwhile (CCT ) is avoided and watchful waiting for signs of placental separartion till 90 seconds end. Massage is not employed but the fundus is frequently palpaple to insure it doesnot become atonic and filled with blood from placenta separation. In cases whom placental separation did not occur within the 90 seconds, we removed the ovum forceps and waited for 30 min for the placental separation .
Theoretical Framework & Background Cortical spreading depressions (CSD) and seizures, are crucial in the development of delayed cerebral ischemia and poor functional outcome in patients suffering from acute brain injuries such as subarachnoid hemorrhage. Multimodal neuromonitoring (MMNM) provides the unique possibility in the sedated and mechanically ventilated patients to record these electrophysiological phenomena and relate them to measures of cerebral ischemia and malperfusion. MMNM combines invasive (e.g. electrocorticography, cerebral microdialysis, brain tissue oxygenation) and noninvasive (e.g. neuroimaging, continuous EEG) techniques. Additionally, cerebral microdialysis can measure the unbound extracellular drug concentrations of sedatives, which potentially inhibit CSD and seizures in various degrees, beyond the blood-brain barrier without further interventions. Hypotheses 1. Online multimodal neuromonitoring can accurately detect changes in neuronal metabolic demand and pathological neuronal bioelectrical changes in highly vulnerable brain tissue. 2. Online multimodal neuromonitoring can accurately detect the impact of pathological neuronal bioelectrical changes on metabolic demand in highly vulnerable brain tissue. 3. The occurrence and duration of pathological neuronal bioelectrical changes are dependent on sedatives and antiepileptic drug concentrations 4. The occurrence and duration of pathological neuronal bioelectrical changes have a negative impact on functional and neurological long-term patient outcome. 5. Simultaneous invasive and non-invasive multimodal neuromonitoring can identify a clear relationship of both methods regarding pathological neuronal bioelectrical changes and metabolic brain status. Methods Systematic analysis of MMNM measurements following standardized criteria and correlation of electrophysiological phenomena with cerebral metabolic changes in all included patients. In a second step neuroimaging, cerebral extracellular sedative drug concentrations and neurological functional outcome, will be correlated with both electrophysiologic and metabolic changes. Due to numerous high-resolution parameters, machine learning algorithms will be used to correlate comprehensive data on group and individual levels following a holistic approach. Level of originality Extensive, cutting edge diagnostic methods are used to get a better insight into the pathophysiology of electrophysiological and metabolic changes during the development of secondary brain damage. Due to the immense amount of high-resolution data, a computer-assisted evaluation will be applied to identify relationships in the development of secondary brain injury. For the first time systematic testing of several drug concentrations beyond the blood-brain barrier will be performed. With these combined methods, we will be able to develop new cerebroprotective treatment concepts on an individual basis.
This study has been designed to evaluate how effective the Bizact tonsillectomy device is in reducing operating time and complications that occur after surgery. This device operates in a different way than the standard device that is used for most tonsillectomies. In 2019, a study was conducted in 186 children and adults using this device in tonsillectomies. Results showed lower blood loss and shortened time in surgery. However, the rate for bleeding as a complication after surgery was the same as other procedures that are used in tonsillectomy
Postpartum hemorrhage, is one of the most deadly complication of pregnancy worldwide and major cause of maternal mortality especially in third world countries .1 PPH affects about 5% of all women giving birth around the world 2 .Primary PPH is defined as ≥500 mL blood loss after vaginal delivery or ≥1000 mL after CS delivery within 24 hours after birth1 . Globally, almost one quarter of all maternal deaths are linked with PPH 2. Due to the high prevalence of anemia among pregnant women in low-resource settings, the outcome of PPH is often deteriorated, resulting in damaging health consequences 3. Roughly in 70% of cases of primary pph are due to uterine atony11. Uterine atony is due to loss of contraction and retraction of myometrial muscle fibers can lead to severe hemorrhage and shock. There are several reasons behind uterine atony including maternal anemia, fatigue due to prolong labour and rapid forceful labour. Blood loss is double in caesarean section due to use of increased anesthetic agents4. According to WHO use of oxytocin (10 IU, IM /IV) is recommended for prevention of PPH for all births2. Despite its effectiveness, 10-40% of cases need additional uterotonics to ensure good uterine contraction.5 After oxytocin , Misoprostol is increasingly known as a potential treatment option for PPH 5 .Misoprostol is easily available , rapid acting , and cost effective with minimal side effects, however in caesarean section owing to the effect of anesthesia limits its use . In recent study conducted at Egypt, oxytocin plus misoprostol (study group) is compared with oxytocin alone (control group). Incident of pph was significantly lower in study group (p=0.018), as in study group (1.33%) than control group (6.67%)8. Misoprostol is an autacoid substance and act better if placed closed to target organ 9. Several routes of misoprostol, with or without oxytocin, and its result on intrapartum and postpartum hemorrhage are described in the literature. The practice of misoprostol by the intrauterine route during caesarean section is under trial.10. Aim of study is to observe the effectiveness of intrauterine misoprostol in addition to oxytocin to minimize the blood loss during caesarean section.
