Filter by:The goal of this prospective, randomized, controlled, cross-over, multicentric study is to demonstrate the safety of bioLogic Fusion in patients on chronic haemodialysis or hemodiafiltration prone to hypotensive episodes. The main question it aims to answer is: • Which is the number and percentage of individual sessions with reached prescribed post-dialysis body weight in the prescribed treatment time in each single session in hypotensive-prone patients on high-flux haemodialysis or hemodiafiltration within each patient with treatments performed with DialogiQ with (treatment A) or without (treatment B) the bioLogic Fusion option activated? Participants will in addition to their routine dialysis treatment undergo 2 physical examinations and regularly answer questionnaires. A crossover design is used to compare treatments with or without the BioLogic Fusion function activated.
SIH is a debilitating neurological disorder caused by a cerebrospinal fluid leak, with an estimated incidence of 5 per 100,000 persons per year, of which mostly women between the ages of 35 years and 55 years (1). The typical presentation is moderate-to-severe orthostatic headache and several other possible neurological symptoms, that significantly impact patients' quality of life (2). Treatment of SIH usually starts with conservative measures, consisting of strict supine bed rest, hydration, caffeine, and simple analgesics (3). The vast majority of patients will require invasive treatments for their CSF leak, such as epidural blood patches, fibrin glue patches, endovascular coiling, and/or surgical repair (4). These specialized treatments are only offered in tertiary care centers and require specialized personnel and resources, which implicates a certain waiting time for the patients before permanent treatment is offered (5). In the meantime, due to the lack of an effective and accessible alternative, patients continue to suffer. The GONB has been reported as a simple, safe, and effective treatment to provide short-to-intermediate term relief of migraine (6), cervicogenic headache, cluster headache (7), occipital neuralgia, and more recently, post-dural puncture headaches (PDPH) (8). As the pathophysiology of intracranial hypotension caused by SIH or PDPH is very similar (9), it is stipulated that the effect of GONB will be similar for SIH patients. However, to date, no studies exploring the efficacy of GONB for SIH have been performed. We propose to do a prospective observational study to explore the outcome of GONB for SIH. GONB can serve as a bridge therapy to control the debilitating headache of SIH while patients are awaiting permanent SIH treatment. Moreover, GONB can be performed by physicians of different specialties including neurology, which makes it an accessible treatment for all patients. Lastly, by offering better symptom control, this intervention could potentially restore patients' ability to work and reduce healthcare costs.
The goal of this observational study is to evaluate preoperative measures of abdominal circumference in patients admitted for a cesarean section. The main questions it aims to answer are: - Can preoperative abdominal circumference predict patients with difficult spinal anesthesia - Can preoperative abdominal circumference predict the occurrence of maternal hypotension during cesarean section Participants will be examined preoperatively in terms of visibility and palpation of spinous processes, abdominal circumference will be measured in the supine and sitting positions with other clinical parameters. Spinal anesthesia will be performed by the same experienced anesthesiologist with a standardized procedure. The number of skin punctures, needle reorientations, traumatic Cerebrospinal fluid, need for a paramedian approach or failure will be recorded. Maternal blood pressure and vasopressor requirements will also be monitored.
Arterial hypotension is a frequent complication of general anesthesia and a significant contributor to postoperative complications. It is a critical marker for the development of acute renal failure and postoperative myocardial infarction. Chronic heart failure (CHF) patients are increasingly encountered in the operating room, and their perioperative morbidity and mortality are substantial, with specific management lacking precise recommendations. The main objective is to assess the impact of a diluted norepinephrine bolus on cardiac output in chronic heart failure patients experiencing arterial hypotension after anesthesia induction.
High blood pressure is a risk factor for end-stage renal disease and is common in patients undergoing maintenance hemodialysis. Intradialytic hypotension is associated with an adverse prognosis. More knowledge is needed to identify patients at high risk for intradialytic hypotension and dialysis-associated hypotensive episodes. The aim of this observational single-center pilot study is to evaluate whether point-of-care ultrasound measurements may predict intradialytic hypotension and orthostatic blood pressure falls, in patients with chronic kidney disease who undergo maintenance hemodialysis.
The study will investigate whether the use of Goal Directed Hemodynamic Therapy implemented with the HPI algorithm using a treatment algorithm will reduce the incidence of hypotension and improve treatment of hypotension.
The most important symptoms of nasolacrimal duct obstruction are excessive tearing and mucoid discharge. The proposed treatment in this regard is dacryocystorhinostomy (DCR) surgery. Therefore, hemostasis is of great significance in performing DCR surgery. In this regard, the reduction of controlled hypotension and the control of hemodynamic responses of the body to stress effectively reduce the bleeding volume during surgery. Hence, there is no enough studies about controlled hypotension in DCR we decided to perform such a comparison between the effect of dexmedetomidine and labetalol in providing controlled hypotension during DCR surgery.
Range of motion (ROM) is a term used to describe the amount of motion in each joint in our body. Every joint in the body has a normal range of motion. Maintaining the normal opening of the joints is achieved through movement. ROM exercises reduce contractures and are very important in terms of helping to preserve muscle movements. ROM exercises are an inexpensive method that can be applied in any environment, either as a group or individually, covering all muscle-joint groups. Individuals with disabilities can perform ROM exercises individually or receive support from healthcare professionals. It provides support to venous return by increasing muscle strength in patients who are immobilized for a long time. Based on this information, the aim of our study is to investigate the effect of lower extremity ROM exercises during hemodialysis on hypotension, fatigue and hemodialysis comfort. The patients will be divided into the intervention group (n=32) in which 20 minutes of ROM exercise was applied and the control group (n=32) in which routine nursing care was given. For the sample calculation of the study, G power analysis was performed, type 1 error was 0.05; type 2 error 0.20; With a power of 0.80, a minimum sample size of 64 people for the experimental and control groups. The case group will be given lower extremity ROM exercises for a total of two weeks. Each individual in the case group will have lower extremity ROM exercises, each of which will last 20 minutes, at the beginning of the session and at the beginning of the hour until the end of the session. "Piper's Fatigue Scale" and Hemodialysis Comfort Scale" in the data collection form will be applied again at the end of the 1st and 2nd weeks after the sessions have started. The vital signs of the individual will be followed and recorded at each session.
In this prospective, randomized, single-blind study, we aim to compare the effects of general anesthesia and spinal anesthesia on postoperative myocardial injury in elderly patients undergoing hip surgery. Cardiovascular events are a leading cause of mortality and morbidity following non-cardiac surgery, with myocardial injury after non-cardiac surgery (MINS) being a significant concern. MINS, characterized by asymptomatic elevation of troponin levels without accompanying ECG findings, is closely associated with postoperative mortality. With the increasing prevalence of comorbidities in the elderly population and the rising frequency of non-cardiac surgeries in this demographic, understanding the effects of different anesthesia types on postoperative myocardial injury is crucial.
The purpose of this study is to investigate whether norepinephrine(N), phenylephrine(P) or ephedrine(E) have different effect on cerebral oxygenation in abdominal surgery with propofol or sevoflurane.
