Filter by:Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide. Besides causing symptoms that impair movement, PD also causes non-motor symptoms, such as problems thinking and orthostatic hypotension (OH), i.e., low blood pressure (BP) when standing. About one-third of people with PD have OH, which can cause sudden, temporary symptoms while upright, including lightheadedness, dizziness, and fainting. People with PD and OH can also experience problems thinking that happen only while upright and not while sitting - this can occur without other symptoms, such as feeling dizzy or faint. However, the level of low BP that can affect thinking remains unknown, and no guidelines exist for treating OH when it happens without symptoms. This is significant because OH could be a treatable risk factor for thinking problems in PD, but OH is often not treated if people do not report obvious symptoms. This project's goal is to determine how BP affects brain function in PD. The proposed experiments will measure BP and brain blood flow continuously in real-time using innovative wearable technology. Persons with PD with OH and without OH will undergo repeated cognitive tests while supine (lying down) and while upright. I will study the associations between BP, thinking abilities, and brain blood flow, and will compare groups with and without OH. These findings could be important because if a certain level of BP correlates with thinking abilities, then treating OH in PD may prevent thinking problems, which would improve health-related quality of life and reduce disability and healthcare costs.
HPI monitoring and the adoption of therapeutic interventions before hypotension occurs should be ensure a shorter time of intra-operative hypotension (MAP < 65 mmHg) during deceased-donor kidney transplant surgery. The control group is represented by patients undergoing the same surgical procedure with hemodynamic monitoring with invasive blood pressure monitoring which represents the gold standard for this surgery. HPI monitoring has not yet been investigated during this surgery.
This prospective observational study aimed to investigate whether there is a relationship between weight, height, BMI, abdominal circumference (AC), hip circumference (HC), and AC-to-hip ratio with the incidence of hypotension in patients undergoing cesarean section under spinal anesthesia.
Comparison of the incidence of hypotension under remimazolam and propofol-based anesthesia in patients undergoing breast surgery under general anesthesia
Maternal hypotension after subarachnoid block is a frequent and deleterious complication during lower segment caesarean section (LSCS). Prophylaxis against hypotension using vasopressors had become a standard recommendation. In mothers with preeclampsia, post-spinal hypotension is less frequent compared to healthy mothers; thus, the latest guidelines do not recommend using vasopressors in preeclampsia patients unless there is a hypotensive episode . The incidence of post-spinal hypotension in mother with preeclampsia is nearly 25%. The commonly used vasopressors during CS are ephedrine, phenylephrine, and recently norepinephrine. The use of ephedrine is usually accompanied with maternal tachycardia and foetal acidosis. Phenylephrine (PE) had been the first line for prevention and management of maternal hypotension; however, its use in mothers with preeclampsia had not been adequately investigated. Thus, the best vasopressor for management of hypotension in mothers with preeclampsia is unknown. Norepinephrine (NE) is an alpha adrenergic agonist with weak beta adrenergic agonistic activity; thus, it does not cause significant cardiac depression as phenylephrine does. NE was introduced for use during CS with promising results when used as infusion and as boluses in healthy mothers . The use of NE boluses in management of hypotension in preeclamptic mothers was not adequately investigated. A dose 4 mcg NE was recently evaluated in preeclamptic mothers. In this study, we will compare 3 NE bolus doses (3 mcg, 4 mcg, and 5 mcg) in management of maternal hypotension after spinal block during CS in preeclamptic mothers.
Background: Mucosal bleeding is the most frequent complication with endoscopic nasal surgeries, as it interferes with the optimal visualization of the intranasal anatomy, leading to increased complications, operation duration, and blood loss. There are several pharmacological techniques for the appropriate control of intraoperative bleeding. Objectives: To compare the safety and efficacy of oral labetalol versus oral metoprolol as a premedication for controlled hypotensive anesthesia during endoscopic nasal surgeries. Patients and Methods: This is a randomized, double-blind, phase four, comparative clinical trial; carried out on 60 patients, who were candidates for endoscopic nasal surgeries under general anesthesia at our hospital. Patients were randomly allocated into two equal groups; group L, received oral labetalol, and group M, received oral metoprolol.
1. To estimate sensitivity and specificity of preoperative IVCCI, max aortic diameter and IVC:Ao index as predictors of hypotension after induction of general anesthesia. 2. To compare accuracy of preoperative values of IVC: Ao index to preoperative IVCCI in prediction of hypotension after induction of general anesthesia.
This randomized, parallel-design trial will evaluate specific clinical and physiological effects of whole blueberries in adults 70 years of age or older.
The purpose of this study is to investigate whether protocolized vasopressor use for patients with normal blood pressure undergoing rapid sequence intubation improves hemodynamic parameters and mitigates adverse events. The hypothesis is that use of vasopressors during Rapid Sequence Intubation will prevent substantial decreases in blood pressure when compared to normal intravenous fluids.
Background Intraoperative hypotension is associated with increased morbidity and mortality. The Hypotension Prediction Index (HPI) is an advancement of the arterial waveform analysis to predict intraoperative hypotension minutes before episodes occur enabling preventive treatments. This study will test the hypothesis that a hemodynamic treatment protocol based on HPI working with non-invasive ClearSight system reduces intraoperative hypotension when compared to standard goal directed therapy (GDT) in patients undergoing gynaecologic oncologic surgery. Methods A retrospective analysis of 68 adult consecutive patients undergoing gynaecologic oncologic surgery with non-invasive arterial pressure monitoring using either index guidance (HPI) or classic ClearSight system waveform analysis depending on availability (ClearSight, n = 36; HPI, n = 32) will be conducted. A hemodynamic GDT protocol was applied in both groups. The primary endpoint will be the incidence and duration of hypotensive events defined as MAP <65 mmHg evaluated by time-weighted average of hypotension.
