Filter by:Intravenous dexmedetomidine has been reported to decrease the occurrence of postoperative delirium (POD) in elderly patients. Nevertheless, some previous studies have indicated that intratracheal dexmedetomidine and intranasal dexmedetomidine are also effective and convenient. The current study aimed to compare the effect of different administration routes of dexmedetomidine on POD in elderly patients.
The anesthetic efficacy and safety of continuous spinal anesthesia and comparing it with general anesthesia technique in sepsis diagnosed patient.
Aortic valve stenosis is the most common debilitating valvular heart lesion in old patients. Transcatheter aortic valve replacement (TAVR) is an emergent technique for high-risk patients with aortic stenosis. In recent times, treatment has expanded to also include low- and intermediate-risk individuals. General anesthesia offers many advantages, mainly regarding the possibility of an early diagnosis and treatment of possible complications through the use of transesophageal echocardiography. Propofol is the most used sedative-hypnotic agent for the induction and maintenance of general anesthesia. However, adverse events such as hypotension, and bradycardia are associated with propofol sedation. Ciprofol is a novel anesthetic/sedative agent similar to propofol, with an equivalent efficacy ratio to propofol of 1/4 to 1/5. Ciprofol has properties of fast onset of action, rapid recovery, reduced injection pain and stable cardiorespiratory function, making it a promising alternative to propofol. The aim of this study is to explore the safety and efficacy of ciprofol when used for general anesthesia in patients undergoing transcatheter aortic valve replacement compared to propofol.
This study will detect whether prior exposure to general anesthesia multiple times is associated with an increased incidence of awareness with explicit recall (AWR). This is especially important because patients who need to undergo multiple events of general anesthesia are medically some of the most vulnerable populations. The study hypothesizes that patients with significant exposure to general anesthesia have a higher incidence of AWR. This study may help clinicians and patients to better understand how to manage anesthesia care so that the safety and comfort of patients can be improved.
It is known that morbidly obese patients are often accompanied by cardiovascular complications such as hypertension, cardiac hypertrophy, and diastolic dysfunction, and are known to increase the risk of hypotension during anesthesia induction. Remimazolam is widely used in Japan and the United States, and it was approved as a drug for general anesthesia and sedation in Korea in 2021. It was reported that remimazolam caused less hypotension after induction of anesthesia than propofol. However, there is no study on the use of remimazolam in patients undergoing bariatric surgery due to morbid obesity. Therefore, through this study, we plan to check whether remimazolam is safe and effective as an anesthetic-inducing agent for morbidly obese patients undergoing bariatric surgery.
The Aim of the study was to determine the impact of the videolaryngoscpe on the time needed to intubate. This was a Prospective, randomized, simple blinded study. The participants intubated patients for surgery under general anesthesia either with direct laryngoscpy or with videolaryngoscopy.
In our study, it was aimed to show the contribution of intraoperative intravenous magnesium sulfate administration to peroperative opioid consumption and postoperative analgesia.
Researcher want to compare and evaluate the effect of sugammadex on postoperative recovery, with a focus on the occurrence of postoperative urinary dysfunction, in patients who have undergone regular abdominal surgery within a year of being infected with and treated for COVID-19. Post COVID-19 condition is a new and poorly understood clinical syndrome with potentially significant and life-altering consequences. Recent studies suggest that patients who have recovered from COVID-19 may experience autonomic dysfunction and be at risk for autonomic dysregulation/syndrome. In most patients undergoing general anesthesia, neuromuscular blockers are used, and their residual effects delay the recovery of autonomic function after surgery, leading to problems such as worsening bladder and bowel function. Therefore, reversal agents are used to aid in postoperative muscle recovery, with sugammadex and neostigmine being commonly used in clinical practice. While sugammadex is generally expected to result in faster postoperative recovery, limited reports exist on its effectiveness in patients who have recovered from COVID-19. This study aims to verify whether sugammadex is more effective than neostigmine in aiding the recovery of bowel and pulmonary function after surgery in patients who have recovered from COVID-19.
The risk associated with arterial hypotension during general anesthesia for surgery has been demonstrated , but the threshold at which consequences for perfusion of one or more organs appear varies according to the mechanism of hypotension, associated abnormalities (HR, cardiac output, and oxygen transport), and the patient's terrain. Currently, a mean arterial pressure greater than 60 mm Hg and a reduction of less than 30-50% from the value measured before general anesthesia are commonly used treatment thresholds to ensure good perfusion of all organs. Normally, cerebral blood flow is auto-regulated, which allows cerebral blood flow to adapt to oxygen requirements and to different levels of blood pressure, both high and low. However, this protective mechanism may fail for a degree of hypotension that depends on several factors such as the age or vascular status of the patient. The aim of the study is to measure non-invasively, easily and reliably the variations of cerebral perfusion in patients with and without cardiovascular risk factors during controlled variations performed during routine care to set the blood pressure level within the recommended safety standards during general anesthesia. What is the target level of blood pressure tolerable for a patient under general anesthesia? Is there a simple and non-invasive way to measure the level of cerebral blood flow autoregulation and especially its adequacy to the brain's oxygen needs?
The investigators aimed to investigate the deep learning model to predict intraoperative hypotension using non-invasive monitoring parameters.
