6 Clinical Trials for Various Conditions
This study investigates whether television viewing or music listening can reduce pre-operative anxiety and improve surgical outcomes for patients undergoing cataract surgery. It aims to determine the effectiveness of these interventions compared to a control group and assess their impact on physiological markers of anxiety as well as the incidence of intra-operative hypertensive events. The key questions that are to be answered are: 1. Does watching television before cataract surgery decrease intraoperative hypertensive events and/or pre-operative anxiety in patients? 2. Does listening to music before cataract surgery decrease intraoperative hypertensive events and/or pre-operative anxiety in patients?
The goal of this prospective randomized double-blind study is to determine if an ultrasound guided peri-arterial injection of local anesthetic (LA) superomedially the femoral artery via peripheral nerve catheter reverses ischemic hypertension associated with prolonged lower extremity tourniquet time.
The purpose of this prospective randomized double-blind study is to determine if the novel technique of ultrasound guided peri-arterial injection of local anesthetic around the femoral artery decreases ischemic hypertension associated with prolonged lower extremity tourniquet time during total ankle arthroplasty (TAA) and foot fusion surgeries. Patients will be randomized 1:1 to receive either local anesthetic or saline, which will be injected superomedially to the femoral artery in an attempt to block sympathetic afferents and decrease tourniquet associated hypertension intraoperatively.
The objective of this study is to prospectively evaluate the therapeutic effectiveness of with blood pressure management using intraoperative neurophysiological monitoring with SSEP and EEG to reduce perioperative stroke. The central hypothesis is that perioperative stroke occurs from emboli in the setting of significant hypoperfusion resulting in ischemia, which leads to infarction. The impact of the proposed research is that, if significant SSEP and EEG changes can be used to identify cerebral perfusion, then timely therapeutic interventions to effectively reduce the impact of perioperative stroke can be directed.
The purpose of this study is to prospectively determine the association between incidence of neurological morbidity and minimum fractional blood pressure reached during laminectomy procedures under general anesthesia in hypertensive and normotensive subjects 40 years old and older.
The purpose of this study is to determine whether continuing or discontinuing furosemide (a diuretic) on the day of elective noncardiac surgery for those who take furosemide on a chronic basis, causes more intraoperative hypotension (low blood pressure) during surgery. Our hypothesis is that the usual practice of continuing furosemide on the day of surgery would contribute to more hypotension during surgery than discontinuing furosemide.
