181 Clinical Trials for Various Conditions
This is a large pragmatic multicenter trial comparing maintenance of general anesthesia with total intravenous anesthesia using propofol versus volatile agent (sevoflurane, isoflurane, or desflurane) during cancer surgery. The primary endpoint is all-cause mortality.
Asses the effect of the use of Patient State Index (PSI) monitoring on difference in emergence profiles in the elderly (age \>65 yrs) population to develop a cost-benefit profile. Assess differences in Quality of Life using the QoR-40 (a validated 40-item questionnaire on quality of recovery from anesthesia) between the two treatment groups.
Establish the range of index values for the SNAP II corresponding to each anesthetic state studied.
Numerous efforts have focused on the development of closed-loop systems to control anesthesia using the electrical activity of the brain (EEG) and EEG-based parameters as surrogate measures of anesthetic depth. New systems have been recently developed to considerably improve anesthetic control using model-based, patient-adaptive methods. The purpose of this study is to evaluate the clinical efficacy of a new intelligent software, ReinLoop, in delivering closed-loop, patient-specific hypnosis.
Purpose of this study is to see if different levels of anesthesia have an effect on hearing spoken words without awareness of having heard them or anxiety after surgery.
General anesthesia allows people to have surgery without experiencing the procedure or pain. To remain unconscious, the depth of sleep must be monitored. Various monitors have been developed, one of which is BIS (short for bispectral index). BIS monitors the level of sleep during anesthesia and improves patient recovery because the amount of sleep drugs can be fine-tuned to the individual. Patients who need a lot to stay asleep get more, and those who need less get less. As a result, patients tend to wake up faster with BIS monitoring as compared to standard practice not using BIS. Little is known about the long-term effects of BIS monitoring. This study investigates whether BIS monitoring during anesthesia improves long-term outcome, well after surgery is over. The hypothesis is that it does. Two groups of patients are compared: one in which BIS monitoring was used, and one in which it was not. Groups are compared on tests of memory, concentration and mental well-being, to see if one does and feels better than the other. The investigators also take blood samples to see how well patients' bodies deal with the surgery. The investigators expect the BIS monitoring group to do better.
Surgical repair of hip fractures may be performed with various anesthetic techniques, but are most commonly completed under general anesthesia (GA) or neuraxial anesthesia (NA). Numerous prospective and retrospective studies demonstrate improved morbidity and mortality when NA is used; however, many surgeons prefer the use of GA with neuromuscular blockade (NMB) due to the perception of better operative conditions. This study aims to compare the operative conditions obtained from the use of combined GA and spinal with NMB vs. the use of GA with spinal without NMB. 84 patients will all receive a single shot spinal and GA and then will be randomized to receive either NMB or placebo. The fracture reduction time will be measured.
The study hypothesizes that adding 60% nitrous oxide to a steady state sevoflurance or propofol anesthetic will lead to a decrease in both BIS and Entropy indices during a constant level of surgical stimulus
The purpose of this study is to investigate the effectiveness of various oral analgesic regimens in minimizing post-operative pain and discomfort in young children following dental rehabilitation under general anesthesia (DRGA). In this randomized controlled trial, three analgesic regimens following DRGA in Franciscan Children's Hospital will be compared using both self-report and behavioral measures. The analgesic therapies to be investigated are ibuprofen monotherapy, alternating ibuprofen and acetaminophen dual-therapy, and combined ibuprofen and acetaminophen dual-therapy. For the purposes of this study, combined therapy is defined as the simultaneous administration of acetaminophen and ibuprofen at regular intervals, whereas alternating therapy is defined as one analgesic (acetaminophen or ibuprofen) administered within a 3 hour interval of the other.
The purpose of this study is to determine if lower extremity elevation (LEE) will reduce the incidence of postinduction hypotension, to compare the utilization of vasoactive medications after induction in patients with LEE and patients without LEE and to determine if LEE will increase measured cardiac output
The SOAP registry is a prospective, multicenter, electronic registry. The goal is to investigate the indications, mode of airway management, predisposing factors, and obstetric and anesthetic outcomes of pregnant patients who receive general anesthesia for cesarean delivery.
In this preliminary, crossover investigation the investigators will examine the effect of oxygen supplementation on the recovery of breathing in the immediate post-anesthesia period.
It is well established that preterm inguinal hernias discovered in the NICU pose a significant surgical risk due to the associated co-morbid conditions that accompany these patients. Currently, the standard of care in the United States is general anesthesia. There have been studies that have established that elective outpatient repair of inguinal hernias found in the NICU can be safely performed. Patients that are ready for discharge from the NICU will have inguinal hernia repair prior to leaving. Inguinal hernia repair will also be done on those premature infants that are seen in the Nemours surgical clinic. Spinal anesthesia is currently the most common anesthetic procedure used in the surgical treatment of preterm inguinal hernias after general anesthesia. Caudal catheter technique has been proven to safely provide post-operative care of premature infants. The caudal catheter technique involves placement of a small catheter under ultrasound guidance into the caudal epidural canal to allow re-dosing of local anesthetic during the case and has been shown to be safe and effective management in neonates (Somri M, 2007).
The effect of the location of tetanic stimulus on photoplethysmography signals will be studied in patients under general anesthesia.
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.
The main aim is to see if danavorexton can help improve people's breathing in the recovery room after abdominal surgery.
The goal of this survey will be to assess the opinions and reticence of patients who have undergone surgical procedures that required the usage of general anesthesia both before they underwent the procedure and afterwards.
This study compares general anesthesia and spinal anesthesia for vNOTE tubal sterilization. A direct comparison of these methods has not been done before for this surgical approach. Investigators will aim to compare the two methods to determine the differences in perioperative complications, postoperative pain, postoperative nausea and vomiting, and the time to get the patient ready for discharge from the recovery room.
Neurotrack™ is an FDA-approved device for measuring and tracking cognitive decline, as may occur with age-related cognitive decline and Alzheimer's disease. The device uses a webcam (World Wide Web enabled camera) to assess eye-tracking as the subject views black-and-white images on the computer screen. The test takes less than 5 minutes to complete. This study will examine the feasibility and utility of pre-operative assessment of cognition using Neurotrack™ technology. The predictive value of Neurotrack™ will be compared to our previous work using pupillometry. The primary outcome is a measure of delirium in the recovery room and secondary outcomes include total length of stay, intensive care unit (ICU) length of stay, and readmissions within 30 days of surgery.

In this randomized-controlled trial the investigators will examine the effect of oxygen supplementation on the recovery of breathing for 90 minutes in the immediate post-anesthesia period starting from extubation of the trachea.
In the PATHFINDER 2 trial, the study investigators will test the intraoperative EEG-guided multimodal general anesthesia (MMGA) management strategy in combination with a postoperative protocolized analgesic approach to: 1. reduce the incidence of perioperative neurocognitive dysfunction in cardiac surgical patients 2. ensure hemodynamic stability and decrease use of vasopressors in the operating rooms 3. reduce pain and opioid consumption postoperatively
The purpose of this study is to evaluate the effectiveness of a preventive strategy in increasing return to follow up and recall appointments.
This study investigates the use of Google Translate "Conversation Mode" translation service to improve communication about pain and nausea with Spanish-speaking patients who are recovering after surgery. The Google Translate "Conversation Mode" translation application is designed to provide translation from one language to another and used to allow the nurse or study doctor to communicate with patients in Spanish by asking pre-prepared questions through an electronic device such as an iPad or iPhone. Google Translate "Conversation Mode" may facilitate assessment of pain and nausea after surgery in Spanish speaking patients.
This study is comparing total intravenous anesthesia with propofol with a regional nerve block against general anesthesia with a regional nerve block on the primary endpoint of time to meet discharge criteria.
50 million patients undergo surgery each year in the United States. Postoperative mortality is considered the third leading cause of death worldwide. Hypotension during surgery have been linked to increased postoperative morbidity and mortality. Episodes of hypotension during surgery are associated with an increased risk of acute kidney injury, stroke, cardiac events and death. Treating or preventing hypotension during general anesthesia and major surgery was found to improve outcomes. At this time, it is unclear what is the best vasopressor to maintain blood pressure during surgery under general anesthesia. With this pilot pragmatic trial, the investigators will explore the impact of norepinephrine (NE) or phenylephrine (PE) on post-operative events in patients undergoing major surgery with general anesthesia and needing vasopressors infusion to maintain their systemic arterial pressure.
This is a multicenter, randomized, double-blinded, propofol-controlled, Phase 3 clinical study to evaluate the efficacy and safety of HSK3486 for induction of general anesthesia in adults undergoing elective surgery.
This study compares changes in brain waves in women with gynecologic cancers who have or have not received chemotherapy and who are scheduled to receive surgery as part of their standard care. Electroencephalography is a test that measures brain waves and may help learn if sensitivity to anesthesia is higher in women who have received chemotherapy than women who have not. This study may help researchers learn if receiving chemotherapy before surgery can affect the way the brain responds to anesthesia during and after surgery.
The investigators intend to recruit 600 participants to see if alpha power during anesthesia is influenced by analgesic medication and associated with a reduction of delirium following surgery.
