Active clinical trials for "Shock"

In patients with septic shock, low levels of circulating immunoglobulins are common and they are kinetic, particularly of immunoglobulin M (IgM), seems to be related with clinical outcome. These observations, combined with the pivotal role of immunoglobulins on host immune response to infections, led to consider therapy with polyclonal intravenous immunoglobulins a promising option in patients with septic shock. IgM-enriched preparations have been used since now most of all at a standard dose recommended by the producer although a more tailored approach may improve patients' outcomes. This study hypothesizes that in patients with septic shock and low IgM immunoglobulins titers at shock onset, adjunctive treatment with a personalized dose of IgM-enriched immunoglobulins based on IgM serum titers of the patient may reduce mortality compared to a standard dose of IgM-enriched immunoglobulins. The study is designed as a multicentre, national, interventional, randomized, single-blinded, prospective, investigator-sponsored, two arms study. Patients will be randomly assigned to IgM titer-based treatment or flat treatment group in a 1:1 ratio. One group of patients will receive IgM-enriched immunoglobulins adjunctive treatment in a standard dose of 250mg/kg for 3 days. The other group will receive IgM-enriched immunoglobulins adjunctive treatment in a variable dose calculated taking note of the extent of IgM deficit, in order to achieve an IgM threshold value of 100 mg/dL or above. IgM preparation will be administered in this group up to the withdrawal of vasoactive drugs with a maximum allowed of 7 days. The confirmation of the efficacy of a tailored strategy for IgM-enriched immunoglobulin administration in reducing the mortality rate among patients with septic shock and low IgM titers will lead to a revision of the current clinical practice in the use of this adjunctive treatment.

In this prospective randomized controlled trial, investigators aim to study the effects and safety of bicarbonated Ringer's solution in patients with septic shock compared with lactated ringer's solution, and provide evidence for current fluid resuscitation strategies for septic shock.

: This prospective randomized observational study aimed to compare behavior of artificially collapsed blastocysts to blastocysts that were vitrified without artificial collapse.

The inflammatory response represents an important, central component of sepsis. Therefore, it is believed that blunting inflammation will decrease mortality. In vivo test series with mice that had undergone cecal ligation and puncture (recognized sepsis model), physostigmine salicylate significantly inhibited the release of various cytokines (tumor necrosis factor α, interleukin1β, and interleukin 6). These results were similar to those obtained by vagus nerve stimulation. In animal sepsis model using physostigmine not only decreased inflammation but also, diminished the decrease in blood pressure following infection. Animals treated with the peripheral choline esterase inhibitor neostigmine showed no difference compared with physostigmine-treated animals. Therefore, this study aims to investigate the efficacy of choline esterase inhibitors as adjuvant therapy in patients with sepsis or septic shock. Outcome measures include: percentage reduction in procalcitonin blood level, percentage of patients achieving significant reduction in procalcitonin levels, Mean Sequential Organ Failure Assessment score, percentage decrease in lactate dehydrogenase blood level, length of stay in hospital intensive care unit, and in hospital mortality.

The purpose of this study is to evaluate the incidence of hypotension based on the discontinuation order of norepinephrine and vasopressin in patients receiving concomitant norepinephrine and vasopressin infusions for the treatment of septic shock.

Dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) are among the leading causes of pediatric hospitalization in Asia.Mortality rates range from 1% at centres experienced in fluid resuscitation, to upto 44% in established shock.The mainstay of DSS treatment is prompt, vigorous fluid resuscitation with isotonic crystalloid solutions, followed by plasma or colloid solutions for profound or continuing shock. However, this administration is often associated with fluid overload and induces edema in these patients. Hence, we planned a parallel, randomized controlled trial comparing the efficacy and safety of solution containing half molar sodium lactate (Totilac™) with standard treatment(isotonic crystalloid Ringer's Lactate) in pediatric Dengue Shock Syndrome patients, using plasma soluble Vascular Cell Adhesion Molecule(sVCAM-1) levels as an indicator. Hypertonic solutions restore hemodynamic status rapidly with increased cardiac performance and improved tissue perfusion. This is obtained with much smaller volumes.We plan to assess the efficacy and safety of hypertonic sodium lactate in resuscitation of DHF/DSS patients.

The purpose of this study is to assess the effectiveness from early infusion of norepinephrine in pediatric patients submitted to mechanical ventilation for the use of sedative and analgesics drugs.

The goal of this study will be to determine if a lower than normal blood pressure during surgery for bleeding in the abdomen or chest will result in decreased bleeding and decreased chance of death.

The trial investigates the effect of cytokine elimination in patients with septic schock and acute renal failure with need for renal replacement therapy on the integrity of cerebrovascular autoregulation. Patients with inclusion criteria were randomly assign in either use of CytoSorb filter integrated in renal replacement therapy versus non additional filter an renal replacement therapy alone. Cerebrovascular autoregulation will be measured with transcranial Doppler ultrasound and correlation with arterial blood pressure.

Acute circulatory failure reduces oxygen delivery below cellular requirements, potentially leading to organ failure. Intravenous fluids are generally administered with the aim of increasing cardiac output and restore organ perfusion. Nevertheless, only 50% of patients increase their cardiac output, while in the remainder not only does fluid loading provide no benefit but it also leads to volume overload (peripheral and pulmonary edema). There are two types of resuscitation fluids, colloids and crystalloids. Given their oncotic pressure, colloids should remain in the intravascular space, while crystalloids distribute into the whole extracellular compartment, potentially increasing the risk of tissue edema. Surprisingly, only few studies directly compared albumin and crystalloids in terms of their overload-related side effects. Electrical impedance tomography (EIT) is a noninvasive, radiation-free, lung imaging modality, which shows lung impedance as determined by small electrical currents. An increase in intrapulmonary gas volume increases impedance, while an increase in blood or fluid volume, lowers it. EIT has a high temporal resolution, allowing to assess ventilation and perfusion in real-time. Preliminary data suggest its value to assess the variations of intrathoracic fluid in patients with pulmonary edema. The aim of the present single-blind, randomized, controlled study is to compare the effect of a fluid challenge with albumin vs. crystalloids on EIT-derived lung impedance in a group of 56 critically ill patients with acute circulatory failure. Our hypothesis is that fluid challenge with albumin leads to a lesser decrease in lung impedance, that is a lesser extravasation of fluids into the lungs. Hemodynamic and respiratory variables, blood samples, cardiac ultrasound and EIT measurements will be recorded before the fluid challenge, and repeated at the end of fluid infusion, 20 and 60 minutes after. Factorial Analysis of variance for repeated measures will be used to assess the effects of fluid loading
