Filter by:Although angiographic embolization has been introduced for preoperative management of spine metastases in 1975 and is suggested today by many authors in the management of such pathologies, it needs to be confirmed by RCT. It is a minimally invasive procedure, not free from complications. The recent meta-analyzes, due to the limited number of patients included are not exhaustive about the effectiveness of embolization in the reduction of the intraoperative bleeding, especially in the context of poor / moderate metastasis vascularization. We want to evaluate the efficacy of preoperative angiographic embolization of intermediate / poor vascularized spine metastases in reducing intraoperative blood loss during excision surgery.
Poor uterine tone after the birth of a baby may cause serious bleeding (called postpartum hemorrhage or PPH). This is a major cause of maternal death worldwide. In the developed world the cesarean section rate is increasing. There are two modalities for anesthesia for cesarean section; general and regional (eg. spinal anesthetic). General anesthesia has been associated with increased blood loss compared to regional and the reasons for this may be multifactorial. Some of the anesthesia gases have been studied and there is laboratory evidence to suggest that these gases may reduce the tone of the uterus and therefore cause increased blood loss due to poor uterine tone. To date there has been little study on the intravenous anesthesia agents. These agents are usually administered to anaesthetise the patient at the start of surgery (induction of anesthesia), however they can also be used instead of the gases to keep the patient asleep using a 'total intravenous anesthesia' technique. Laboratory work in rats has suggested that high doses of these intravenous drugs might reduce uterine tone, thus increasing the risk of blood loss. Interestingly, at low doses one of these drugs (ketamine) may actually increase uterine tone. Only one of these drugs has been studied in human uterine tissue. The investigators plan to compare three anaesthesia induction agents on human uterine tissue under physiological conditions in the laboratory. This study will be the first to compare these three drugs on human tissue. The investigators plan to determine the impact of these drugs on spontaneous uterine contractility and also contractilty induced by oxytocin, which is the drug most commonly administered to help contract the uterus after birth. This is important as it will help inform anesthesiologists as to the best drug to use depending on the clinical circumstance. The investigators hypothesize that the intravenous induction agents will cause a dose dependent decrease in spontaneous uterine contractility, similar to what has been described in the rat model. The investigators also expect that exposure to high concentrations of intravenous anesthesia induction agents will cause a blunted contractile response to oxytocin.
Fluid treatment is usually performed with either balanced crystalloid fluids or iso-oncotic colloids, (synthetic colloids, plasma and 5% albumin). Doubts have been raised about synthetic colloids (impairment of renal function and coagulation), and the natural albumin has been used more extensively. Albumin is the main protein responsible for plasma oncotic pressure and its volume expansion effect. An alternative therapeutic option is the mobilization of tissue fluid by infusing a small amount of hyper-oncotic fluid like the 20% albumin solution (endogenous fluid recruitment). The primary objective of this study is to test the effect of 20% albumin on plasma volume expansion and fluid recruitment in the frame of blood loss replacement during cystectomy using established fluid kinetic models. The investigators expect that fluid replacement with crystalloid will be better sustained intravascularly with the administration of 20% albumin and be able to recruit fluid into the vascular compartment.
The aim of this prospective observational study is to evaluate abnormal uterine bleeding in postmenopausal women using 3D(dimensional) ultrasound assessment of endometrial volume .Doppler assessment of endometrium and hysteroscopy and to correlate this finding with pathological finding of endometrial biopsy
Seven different scoring systems used for prediction of perioperative bleeding were compared regarding patients operated for elective open cardiac surgery in the investigator's study.
Terlipressin and somatostatin/octreotide are the first-line choices for the treatment of acute variceal bleeding in liver cirrhosis. Acute kidney injury can develop in patients presenting with acute variceal bleeding. On the other hand, evidence suggests that terlipressin can reverse hepatorenal syndrome. It has been hypothesized that terlipressin can protect the renal function in cirrhotic patients with acute variceal bleeding, except for control of bleeding.
Postmenopausal Bleeding (PMB) is defined as recurrent attacks of bleeding occurring in women after menopause one year at least after stoppage of cycles [
Postpartum hemorrhage (PPH) remains one of the leading causes of maternal mortality and morbidity worldwide, including in France, where it accounts for approximately 20% of maternal mortality. Although numerous studies have examined immediate PPH, very few have explored secondary (also called late) PPH. Moreover, there are no guidelines in France for the management of secondary PPH. Its frequency appears to vary from 0.2% to 3.0% of deliveries. It is, however, difficult to estimate because only severe secondary PPH will lead to hospitalization and the rare publications concern single-center studies. The cause of these secondary hemorrhages is often unknown, due to the lack of routine uterine aspiration. Nonetheless, this aspiration is not always medically justified. The principal objective of this study is thus to establish the incidence of severe late PPH in the general population.
Early endoscopy is an integral part of the management plan for patients presenting with clinical signs of severe or ongoing UGIB. An accurate endoscopic diagnosis and successful endoscopic hemostasis is highly dependent on adequate visualization of the entire gastric mucosa. Metoclopramide has previously been investigated as a prokinetic agent to aid gastric emptying prior to endoscopy, but its widespread adoption is limited by a lack of high quality clinical evidence as well as concerns regarding side effects. Erythromycin is currently the only prokinetic agent recommended by the American and the European guidelines for use in selected patients in order to reduce the need for second endoscopy. Its clinical application, however, is limited by risk of arrhythmia, significant drug interactions, and frequent drug shortages. Azithromycin is structurally related to erythromycin, but is devoid of most adverse side effects associated with erythromycin use. Early evidence suggests that azithromycin may be an effective alternative to erythromycin in the treatment of gastroparesis. The current study, an interventional, randomized, triple-blinded, placebo-controlled clinical trial, is primarily aimed to evaluate the effectiveness of azithromycin as a prokinetic agent in the management of UGIB. It is also aimed to further evaluate the role of metoclopramide as a prokinetic agent in this setting. Outcome measures to be collected in this study include the need for secondary endoscopy, overall mortality, transfusion requirement, length of stay, requirement for surgery, and incidence of adverse side effects. Results from this study would help identify a safe, effective, and readily available prokinetic agent to be used prior to endoscopy.
Characterizing the impact and treatment of reproductive tract bleeding on women and post-menarchal girls with bleeding disorders. Objectives: This is a cross-sectional observational study of women and girls (WG) with bleeding disorders enrolled in the American Thrombosis and Hemostasis Network (ATHN) dataset. Based on the investigators' study of currently available data of WG with bleeding disorders in the ATHNdataset, the investigators hypothesize that the information currently captured in the core data elements of the ATHNdatasest does not adequately capture data specific to WG with bleeding disorders. Further, the investigators hypothesize that it is feasible for Hemophilia Treatment Centers (HTCs) to include data points specific to WG with bleeding disorder when enrolling participants in the ATHNdataset. This hypothesis will be evaluated through the following specific aims: Specific Aim 1: Characterize reproductive tract bleeding in a cohort of WG with bleeding disorders cared for at US HTCs. Specific Aim 2: Characterize the treatment strategies for and the impact of heavy menstrual bleeding in a cohort of females with bleeding disorders cared for at HTCs. Specific Aim 3: Evaluate the feasibility of adding female specific core data points to the ATHNdataset.
