NCT07345403
The goal of this observational cohort study is to prove whether genetic, epigenetic, transcriptomic, proteomic, metabolomic, imaging, voice, and clinical markers can improve prediction of early complications after cardiac surgery in adult patients. The main questions it aims to answer are: Which biological and clinical markers are associated with: new-onset atrial fibrillation (NOAF), acute kidney injury (AKI), postoperative delirium (POD), vasoplegia, postoperative bleeding and 30-day mortality? Can combining these markers improve early prediction of postoperative complications compared with current clinical risk scores? Researchers will analyze a wide range of data collected before, during, and after cardiac surgery and compare patients who develop early complications with those who do not to identify risk factors and early biomarkers. Participants will: Provide biological samples (blood, urine, stool) before and after surgery for genetic, epigenetic, transcriptomic, proteomic, metabolomic, microbiome, and laboratory testing. Undergo standard preoperative and intraoperative imaging and clinical assessments. Allow collection of clinical data related to postoperative outcomes (For some participants) have voice and video recordings performed to help identify early signs of postoperative delirium. This study aims to improve early detection of postoperative complications and support development of personalized diagnostic and treatment strategies for patients undergoing cardiac surgery.
NCT06057675
This study will be a prospective randomized control trial to evaluate the effects of subcutaneously administered TXA among patients undergoing nasal Mohs reconstruction with local flaps at VUMC.
NCT06961175
Perioperative bleeding requiring blood transfusion is common during cardiovascular surgery, especially in procedures requiring cardiopulmonary bypass. Adenosine diphosphate (ADP) plays a fundamental role in platelet function. Several studies have shown that some patients not receiving antiplatelet therapy undergoing cardiovascular surgery have decreased platelet ADP receptor activity; the prevalence of this condition can be as high as 36%. Furthermore, extracorporeal circulation itself has been shown to cause a reduction in platelet function. Platelet dysfunction due to reduced platelet receptor activity after cardiac surgery is potentially a common cause of bleeding, perioperative blood transfusion, and surgical reexploration in patients not receiving antiplatelet agents. However, these studies are conducted with few patients and present some contradictory results, so the evidence is still scarce. The study hypothesis is that preoperative platelet dysfunction for ADP measured by TEG® Platelet Mapping™ is associated with a higher incidence of moderate-severe bleeding after CPB in patients undergoing cardiovascular surgery.
NCT06969326
The purpose of this study is to determine if applying a single dose of topical estrogen cream in the operating room at the end of your hysterectomy (removal of uterus and cervix) improves the postoperative experience with bleeding and potential symptoms of dysphoria (a feeling of discomfort or distress). Topical estrogen cream is sometimes used if patients have increased risk of bleeding with surgery but is not currently utilized in a consistent way. This study aims to answer the question of whether this is a helpful treatment and should be included in standard postoperative care.
NCT05174988
The investigators propose prospectively evaluating if adding separate sutures to the angles of the vaginal cuff before running barbed suture reduces the incidence of patient's perception of bleeding after surgery.
NCT06005831
Uterine compression methods reduce the amount of postpartum bleeding. In our study, we investigated the effect of fundal pressure, which will be created by a sandbag placed on the abdomen, on reducing post-cesarean bleeding. Material and Methods: A total of 482 patients who delivered by cesarean section (CS) in the Obstetrics Clinic of Fırat University Faculty of Medicine between January 2021 and December 2021 were included in this prospective, randomized, single-center study.
NCT05657327
In recent years, with the continuous development of minimally invasive techniques, laparoscopic pancreatic surgery has also been widely used. Although the postoperative mortality rate of laparoscopic pancreatic surgery has been decreasing as the technology continues to improve and mature, the complication rate reported varies widely among centers.The definition and grading criteria of ISGPS on postoperative complications of pancreatic surgery are mostly proposed based on open pancreatic surgery, and most of the data of the later related studies are also for open pancreatic surgery, while the applicability of the definition and grading criteria in laparoscopic pancreatic surgery is still lacking in systematic The study The main purpose of this study is to investigate the applicability of the ISGPS definition and grading criteria for pancreatic fistula, postoperative bleeding and delayed gastric emptying in laparoscopic pancreatic surgery.
NCT05474261
Bleeding after total thyroidectomy remains a rare event that affects early postoperative morbidity, occurring in 0.3% up to 4.2% of cases. Intraoperative bleeding is an unpleasant complication, and it is often easily manageable though postoperative bleeding may represent a life-threatening condition for the patient. Between January 2019 to February 2022 , 250 consecutive patients were listed for thyroidectomy. The Investigators selected 178 patients and divided them in two groups based on the execution of the Valsalva Manoeuvre. The purpose of the investigator is to clarify whether the routine intraoperative execution of a Valsalva manoeuvre (VM) may affect the detection of bleeding that would otherwise remain occult and therefore may manifest in the postoperative period.
NCT02777307
Demonstrate the effectiveness to Hemopatch in controlling postoperative bleeding or reducing of postperative fluid collection after laparoscopic cholecistectomy, morbidity and postoperative hospital stay.
