Filter by:Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Some researchers proposed that the dysregulated response or organ dysfunction can be lessened by reducing the stress response, which further reduce complication and mortality rates of sepsis. Dexmedetomidine is alpha adrenergic receptor agonist, presenting sympatholytic action in certain parts of the brain with anxiolytic, sedative, and pain killing effects. In the experiments of sepsis animal model, dexmedetomidine have been proved to improve serum lactate clearance and the microcirculation. Dexmedetomidine may inhibit inflammation, as it enhances the activity of the immune system while reducing its systemic reaction and lowering cytokine concentrations. There are also evidences in clinical trials with definite safety that dexmedetomidine reduced inflammation, reduced vasopressor requirements and improved organ function. The beta antagonist esmolol has been proposed as a therapy to lower heart rate, thereby improving diastolic filling time, and improving cardiac output, resulting in a reduction in vasopressor support. A recent meta-analysis of 8 randomized studies using esmolol suggested that the 32% risk ratio decreased 28-day mortality, and a meta-analysis of 7 studies using esmolol in patients with sepsis and septic shock was associated with 32% lower 28-day mortality. However, the effect of anti-stress drugs on cerebral hemodynamics is unknown. In this study, investigators are going to apply the technique of transcranial Doppler to assess the reaction of cerebral blood flow in anti-stress group and control group.
It has been reported that non-pharmacological methods can be used as an alternative in addition to pharmacological methods to reduce pain, anxiety, stress and inflammatory response that begins with the surgical incision in the intraoperative period and continues throughout the operation. It has been reported that music can be used as an alternative non-pharmacological method to reduce pain and anxiety in the perioperative period, as well as surgical stress and the related stress response. The aim of this study is to test the hypothesis that music used as a non-pharmacological method in the intraoperative period can reduce inflammatory response in living donor hepatectomy.
The study aims to evaluate the sub-chronic effects of colonic delivery of a postbiotic on stress response, mood state, sleep, and cognition in healthy young subjects with elevated self-reported stress levels. It is hypothesized that oral intake of the postbiotic, when released in the colonic intestinal site, leads to a blunted subjective and objective stress response after a stress induction.
This clinical trial aims to investigate the effects of a 70-day consumption of cranberry juice on cognitive and motor accuracy, mental and physiological stress, and stress response in healthy men and women between the ages of 30 and 55 who engage in multitasking. The trial will utilize a randomized, double-blinded, placebo-controlled design. It is worth noting that studies have shown that over half of middle-aged Americans experience stress, which can lead to cognitive decline and depression. Previous clinical trials have indicated that consuming polyphenol-rich foods can have positive effects on cognitive function in humans. However, no study to date has examined the long-term effects of cranberry juice consumption on cognitive performance, mental stress, and stress response specifically in individuals engaged in multitasking. Based on this gap in knowledge, the investigators hypothesize the following: (1) chronic consumption of cranberry juice will improve cognitive and motor accuracy, as well as mental and psychological stress responses in young adults subjected to intense multitasking. (2) cranberry juice consumption will alleviate the negative consequences of frequent intense multitasking, such as fatigue, mood fluctuations, cognitive impairment, and memory issues. Additionally, it is expected to have a positive impact on stress biomarkers and neurotransmitter levels. By conducting this clinical trial, the investigators aim to shed light on the potential benefits of cranberry juice consumption in improving cognitive performance, mitigating mental stress, and positively influencing stress responses in individuals who engage in intense multitasking.
The goal of this randomised controlled study is to evaluate the effects of storytelling and escape room methods on the level of learning about stress response of nursing students and students' opinions about these methods. The main questions it aims to answer are: - Is there a difference between the pretest-posttest scores of the students who received training on stress response with the escape room method? - Is there a difference between the pretest-posttest scores of the students who were trained on the stress response with the storytelling method? - Is the difference between the knowledge levels of the students who received stress response training with the escape room and storytelling methods statistically significant? The students, who received training on stressors, stress response and the long-term effects of stress through lecture, were divided into two groups four weeks after this training and were retrained on the same subject with escape room and storytelling methods. Before and after the Escape room and storytelling practices, the students' knowledge of the stress response was evaluated. After both applications, focus group discussions were held with the students and their opinions and feedbacks on the applications were evaluated.
The stress response is mediated by the activation of the hypothalamo-pituitary-adrenal axis and the sympathetic nervous system, leading to glucocorticoid and catecholamines release respectively. This stress response is regulated by feedback loops, involving cortical and subcortical structures. Non-invasive brain stimulation applied over the dorsolateral prefrontal cortex modulates the subcortical dopaminergic transmission at rest and can reduce the hormonal and cognitive alterations induced by stress. This study aims to investigate the Non-invasive brain stimulation -induced modulation of dopamine transmission in an acute stress situation.
Inguinal hernia surgery is the most common practice of pediatric surgeons in their clinical practice. As these operations are usually day case procedures, maintaining adequate analgesia is an important component of perioperative care and ERAS protocols. Caudal block, which is one of the analgesic methods used for postoperative pain, is the most frequently used in inguinal hernia surgery and its effectiveness has been proven. Erector spina plane block, which is easy to apply and has a low risk of side effects, is another tool used in the treatment of postoperative pain after inguinal hernia surgery. These are the procedures that are routinely applied in our center with the aim of intraoperative and postoperative effective analgesia.
this study is designed to assess the efficacy of MgSO4 versus high dose fentanyl compared to conventional anesthesia in attenuating stress response to intubation
Perioperative adequate analgesia reduces neuroendocrine stress response and postoperative complications. Because opioids are the most effective parenteral drugs to control pain and stress response, in this prospective randomized double-blinded controlled study we supposed that higher dose of remifentanil may reduce stress marker variations compared to lower dose in patients undergoing laparoscopic cholecystectomy.
The purpose of this study is to find a preoperative biomarker before cardiac surgery with cardiopulmonary bypass related to severe postoperative inflammatory response and circulatory complications. The investigators hypothesize that an increase of the preoperative stimulation of vasopressinergic system (in response to acute or chronic conditions) could lead to a microcirculatory dysfunction and favor the occurrence of vasodilatation during and after CPB and increase the symptoms of an inflammatory response after CPB. By defining a high risk population, a targeted strategy of monitoring and early or preventive treatment could improve postoperative prognosis.
