Filter by:After surgical procedures, interventions to reduce postoperative bleeding are of great importance. In this study, the effect will be investigated of administering tranexamic acid, which is designed for injection, directly onto the raw wound surface (topical application) created during surgery. In this way only a small amount of drug is to reach a large wound area. There will be a higher drug concentration of it in the exposed wound surface than after injection, but only a very low concentration in the body, and no risk of injury from needles. The researchers have recently shown that topically applicated tranexamic acid reduces bleeding in women who had two-sided breast reduction surgery. Now it will be studied whether topically applicated tranexamic acid reduces bleeding from superficial wounds, using as a study model the homogenous wounds created by tangential skin excision when harvesting split skin grafts for skin transplants. Two identical wound surfaces in the same patient will serve as case and control.
Recently, the occurrence and potential impact of pituitary dysfunction after aSAH has gained increasing interest. Several studies have demonstrated pituitary dysfunction after SAH suggesting that pituitary dysfunction may be a contributing factor for residual symptoms after SAH. This is an observational multicentric study aimed to test the prevalence of thyroid abnormalities, other neuroendocrinological dysfunction and their influence on outcome of patients affected by aSAH.
The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.
The objective of this study is to determine the effect of 1g of IV tranexamic acid given within 1 hour pre-operatively on intraoperative blood loss at time of hysterectomy.
This study is a prospective, systematic evaluation to assess the effectiveness and safety of introduction of UBT into PPH care at secondary level and district hospitals in 3 low-resource countries. The first component of the evaluation is a prospective stepped wedge cluster randomized design to assess the potential reduction in PPH-related mortality and invasive procedures (blood transfusion, arterial ligation, hysterectomy and uterine arterial embolization) for PPH performed at participating facilities following introduction of UBT. The second component is a nested cohort analysis to assess the safety and acceptability of UBT among women diagnosed with PPH.
The objective of the study is to demonstrate whether cooling the uterine smooth muscle during cesarean section (following delivery of the fetus) will promote better uterine contraction and involution resulting in lower blood loss, use of fewer uterotonic medications, and fewer hysterectomies following cesarean section for dysfunctional labor.
The primary objective of this study is to assess the safety and efficacy of Tranexamic acid (TXA) in reducing blood loss and transfusion requirements for patients with osteoporotic hip fractures. In addition to assessing blood loss in these patients, complications associated with TXA use would be characterized including systemic (pulmonary embolism, deep venous thrombosis, myocardial infarction, stroke) and surgical site (hematoma, infection) events, need for re-hospitalization or re-operation and 30 day mortality.
The decision to transfuse or not to transfuse blood products is one of the main issues in patients undergoing surgery. The standard laboratory method of hemoglobin assessment is time-consuming, gives intermittent data, and requires venipuncture which is invasive and painful. In the past decade, the use of non-invasive and faster methods, which allow physicians to measure hemoglobin levels at the patient's bedside, have become widespread. One of the tools that make this possible is Spectrophotometric Hemoglobin. However, one of the main concerns regarding this method is its accuracy. Since the accuracy of this assessment depends on the extent of perfusion of the organ on which the probe is placed, use of digital nerve blocks proposed to increase its accuracy. This study aims to evaluate the effects of digital nerve block (with bupivacaine) on the accuracy of non-invasive hemoglobin monitoring by spectrophotometry in patients undergoing spinal surgery.
Comparison of efficacy of rectal misoprostol for reduction amount of blood loss in women undergoing myomectomy, both open and laparoscopic approach
This is a Phase I open-label, parallel-group clinical study in healthy term pregnant females undergoing a caesarean section. Two administrations of oxytocin will be tested, after which uterine contractility will be assessed.
