The current evaluations of the levels of consciousness during anesthesia have limited precision. This can produce negative clinical consequences such as intraoperative awareness or neurological damage due to under- or over-infusion of anesthesia, respectively. The study's objective is to determine and classify biomarkers of electrical and hemodynamical brain activity associated with the levels of consciousness between wakefulness and anesthesia. For this purpose, a parietal electroencephalography (EEG) and a functional near-infrared spectroscopy (fNIRS) measurement paradigm will be used, as well as machine-learning. Volunteering patients (n = 25), who will be subject to an endoscopy procedure, will be measured during the infusion of anesthesia with propofol. EEG and fNIRS parameters will then be related to the Modified Ramsay clinical scale of consciousness.
The aim of this study is to set up a pre and postoperative ambulation score on a population of adult patients and undergoing outpatient surgery operated under locoregional anesthesia and sedation.
This study will be conducted on pediatric patients up to 14 years of age. The effect of two fluid challenge regimes on cerebral and peripheral NIRS will be assessed, in a randomized double blinded controlled trial. The findings will be correlated with two ultrasound measures, previously validated as markers of fluid responsiveness.
The analgesic effect of perioperative use of aripiprazole has not been fully investigated. So, this study aims to test the effects of aripiprazole versus placebo in reducing postoperative pain following laparoscopic hysterectomy and to explore the potential side effects.
To compare the effect of low dose methylprednisolone versus high dose on inflammatory mediators' level and cardioprotective effect after CPB in correction of congenital acyanotic heart disease.
Currently at University of Chicago Medical Center (UCMC) consent for anesthesia is obtained verbally by qualified anesthesia providers. Later this year, we will be moving to a written informed consent form for anesthesia that must be signed by patients before proceeded with elective surgery. We aim to study patient satisfaction and retention of information presented before and after this change is made. After consent for anesthesia is obtained, study personnel will approach patients >= 18 years of age scheduled for elective surgery and, after seeking verbal consent for this study, will administer a questionnaire which will assess patient satisfaction and retention of the risks that were presented.
Aging and frailty make the elderly patients susceptible to hypotension following spinal anaesthesia. The systemic haemodynamic effects of spinal anaesthesia are not well known. In this study, we examine the systemic haemodynamic effects of fractional spinal anaesthesia following intermittent microdosing of a local anesthetic and an opioid. We included 15 patients aged over 65 with considerable comorbidities, planned for emergency hip fracture repair. Patients received a spinal catheter and cardiac output monitoring using the LiDCOplus system. Invasive mean arterial pressure (MAP), cardiac index, systemic vascular resistance index, heart rate and stroke volume index were registered. Two doses of bupivacaine 2,25 mg and fentanyl 15µg were administered with 25 minutes in between. Hypotension was defined as a fall in MAP by >30% or a MAP <65 mmHg
This study aimed to compare the effectiveness of intranasal Dexmedetomidine sedation at Dose of 2 mcg/kg and 4 mcg/kg in Children Undergoing MRI at Cipto Mangunkusumo Hospital
The aim of this study is to determine if the Stable Airway Management device (SAM) is safe in maintaining the airway in a stable, non-obstructing position during anesthetic cases requiring monitored anesthesia care (MAC).
