Filter by: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.
The goal of this clinical trial is to explore raise-bed training Orthostatic Hypotension in Parkinson's Patients. The main question it aims to answer is: Can raise-bed training improve Orthostatic Hypotension in Parkinson's Patients. Patients will be randomly allocated into the control group or the experimental group, all under rehabilitation treatment, the experimental group will be given raise-bed training. The study lasts 21 days for each patient. Researchers will compare Orthostatic Hypotension Questionnaire, Orthostatic Grading Scale, Composite Autonomic Symptom Scale 31 to see if raise-bed training can help improve the symptom
Spinal anesthesia is widely accepted as the anesthetic method of choice for Cesarean section. However, the incidence of spinal hypotension is 50-70%, and the decrease in blood pressure is often rapid and severe. Heart rate variability is influenced by various factors such as the sympathetic nervous system, parasympathetic nervous system, temperature regulation, baroreflex, and endocrine regulation, but high frequency heart rate variability above 0.15 Hz very specifically reflects the parasympathetic nervous system. The ANI monitor calculates heart rate variability mediated by changes in the parasympathetic nervous system. This study aims to determine whether ANI monitor can predict hypotension in patients undergoing a caesarean section under spinal anaesthesia while applying the preemptive vasopressor phenylephrine infusion protocol.
Postural changes during anesthesia can lead to decreased cerebral blood flow and oxygenation, especially when moving from a supine to a prone position. This is particularly relevant during spinal surgery with controlled hypotension. Cerebral oximetry, monitored in the frontal cortex using an O3 sensor, is a noninvasive and continuous method to investigate the impact of anesthetic techniques on cerebral oxygenation in such scenarios.
