Evaluation of the Impact of an Expert Opinion During the Management of Patients With Severe Bleeding...
HemorrhageThe goal of this randomized clinical trial is to evaluate the impact of an expert opinion during the management of patients with severe bleeding on oral anticoagulants. The main question it aims to answer is : • Does an expert help of decision during the management of patients with severe bleeding is superior to classic management ? The centers will be randomized in one of the two groups : control group and interventional group. Patients will be followed for 3 months. At their inclusion they will be managed in conformity of the randomisation of their center. They will be followed at hour 0 + 6 , H0+24 and at the end of hospitalization. After 3 months, they will be called to assess the occurrence of thrombotic events ou hemorrhage complications. Researchers will compare the classic management versus the management with an expert opinion to see if the expert opinion is superior to classic management.
The Effects of Palatal Pre-sutures in Connective Tıssue Graft Surgery
SutureComplication2 moreConnective tissue graft operation is one of the most frequently performed surgical procedures to increase the width of the attached gingiva and to treat gingival recessions. The most preferred donor site during this operation is the palatal mucosa.Reported postoperative complications are usually related to the donor site. Problems such as prolongation of bleeding time, delay in wound healing and severe pain in the palatal region where the graft is taken are frequently encountered. Bleeding control in the palatal donor area is very important for patient comfort. Additional measures may be required to control bleeding, such as sutures with or without hemostatic agents, or acrylic, plastic palatal stents and periodontal pastes prepared before the operation. Suturing the Greater Palatine Artery (GPA) or terminal vessel branches has been shown to be an effective method to control palatal bleeding. Therefore the aim of this study is to evaluate the effectiveness of the pre-suture method applied in the palatal region before the connective tissue graft is taken in reducing hemostasis.Pre-suture method can increase the operator's field of vision and operational comfort. Patient-reported outcomes such as the amount of pain and bleeding in the palatal donor area during and after surgery, painkiller intake, number of days of discomfort, satisfaction, quality of life, and willingness to be treated will be evaluated. In addition, it will be evaluated whether this suture technique affects the healing of the half-thickness flap in the palatal region after obtaining a connective tissue graft with a single incision method.

A Prospective Study of Ranibizumab in the Treatment of Postoperative Recurrent Vitreous Haemorrhage...
Diabetic RetinopathyPostoperative Recurrent Vitreous Hemorrhage2 moreDiabetic retinopathy (DR) is one of the main complications in diabetes, the proliferative diabetic retinopathy (PDR) is the most important one of the reasons leading to decreased vision, PDR is the stage of clinical intervention. Pars plana vitrectomy (PPV) is an effective treatment for PDR, while vitreous haemorrhage (VH) is a common complication after PPV, with incidence ranging from 11.8% to 75%, and is the main cause of reoperation. Anti-Vascular endothelial growth factor (VEGF) therapy for vitreous hemorrhage can inhibit neovascularization and prevent recurrent vitreous haemorrhage after absorption. Previous studies have found that anti-VEGF is a safe and effective treatment for postoperative recurrent VH. In consideration of the psychological and economic factor of patients, this study intends to observe the effectiveness of single vitreous injection of Ranibizumab in the treatment of postoperative recurrent VH on the basis of previous clinical work. Compare the visual acuity, macular thickness, VH recurrence and patient satisfaction between the Ranibizumab group and the PPV group by randomized grouping.To observe the effective rate and clearance time of recurrent VH after Ranibizumab treatment and whether it can effectively reduce the rate of PPV. To provide clinical guidance for the precise treatment of PDR patients, the treatment of PDR patients has important clinical significance and social and economic significance.

MyomaOur study aims to evaluate the efficacy of intracapsular injection of Terlipressin versus Carbetocin injection on hemoglobin level in women undergoing abdominal laparoscopic myomectomy. Moreover, to evaluate their efficacy in decreasing blood loss on operative time and to describe the injection sequelae for the same population. This clinical study will be conducted in compliance with the clinical study protocol and applicable regulatory requirements.
Cervical Spinal Cord Stimulation in Patients With Cerebral Vasospasm After Subarachnoid Haemorrhage:...
Cerebral VasospasmSubarachnoid HemorrhageCerebral vasospasm is characterized by a vasoconstriction of cerebral arteries causing a reduction of cerebral blood flow (CBF) and leading to ischemia and infarction of the brain parenchyma. Cerebral vasospasm is a serious complication of aneurysmal subarachnoid hemorrhage (SAH) with high morbidity and overall mortality of 40-50%. Although the exact mechanisms of spinal cord stimulation (SCS) on the innervation of cerebral vessels are still unclear, several hypotheses have been formulated and studies in animals and human performed with very promising results. This is a proof of concept study to better understand the effect and mechanisms of cervical spinal cord stimulation on cerebral vasospasm after aneurysmal SAH in human.

Intraventricular HemorrhageSubarachnoid Hemorrhage2 moreThe goal of this clinical trial is to evaluate efficacy and safety of evacuation of cerebrospinal fluid, blood, and harmful bacteria from the intraventricular, subdural and subarachnoid spaces by Active Controlled Irrigation and Drainage (IRRAflow) compared to Passive External Ventricular Drainage (EVD). Subjects with intraventricular hemorrhage, subarachnoid hemorrhage, subdural bleeding, and ventriculitis will be randomized to receive the IRRAflow device or EVD device and followed for one month post-procedure to compare outcomes between the subject groups.
Tranexamic Acid to Reduce Blood Loss in Spine Trauma Surgery
Spinal InjuriesSpinal DeformityThis study is designed to evaluate the efficacy of topical tranexamic acid to reduce perioperative blood loss, reduction in postoperative drain output and allogenic transfusion requirements. The proposed study will be a prospective, randomized, double-blind (subject, surgeons, investigators, research coordinators) placebo-controlled study. Patients following high energy trauma who have sustained thoracic or lumbar spine fractures, dislocations or ligamentous injury with resultant instability requiring posterior spinal fusion will be enrolled for this study. Furthermore, patients undergoing elective complex deformity surgery will also be enrolled. Both populations of patients will be randomized into two groups. Group I will receive standard of care operative fixation with topical tranexamic acid intervention (test); Group II will receive standard of care operative fixation with normal saline (placebo) intervention. This study will have a 2-year follow-up and will consist of three periods: screening/enrollment phase up to 21 days from the day of injury to the day of randomization and operative intervention, an inpatient data collection period for 4 days postoperative, and then a follow-up period for 2-years postoperative (visits occurring at 2 week, 16 week, 1 year, and 2 year) time points.
