Filter by:This study seeks to investigate which regions of the brain are relevant in the regulation of cardiac control and how the interplay between HRV and those regions change during different physiological states (stress versus relaxation). In order to achieve this, we will use functional magnetic resonance imaging (fMRI) during an experimental task consisting of deep breathing and a psychosocial stress task (Montreal Imaging Stress Task).
Video-assisted thoracic surgery (VATS) is frequently applied in thoracic surgery operations. VATS has become the standard procedure in minor and major lung surgeries. In recent years, regional anesthesia techniques have also been frequently applied to patients for pain relief. Thoracic paravertebral block (TPVB), erector spinae plane block (ESPB), and serratus anterior plane block (SAPB) are also among the regional anesthesia techniques frequently used in thoracic surgery. General anesthesia (GA) is the main method of anesthesia for thoracic surgery. However, GA can only inhibit the projection system of the cortical limbic system or hypothalamic cortex. GA cannot completely block the transmission of peripheral noxious stimulus to the central nervous system and cannot effectively inhibit the intraoperative stress response. With the addition of peripheral blocks such as TPVB, ESPB, and SAPB, more stable hemodynamics is expected by providing preemptive analgesia in patients. As a result of all these; In this study, we aimed to compare the intraoperative hemodynamic changes of patients who underwent preoperative ESPB in patients who will undergo VATS resection under GA with those who underwent postoperative ESPB.
This study is a cross sectional study
This prospective observational study aims to determine, if an tracheal intubation-related decrease in heart rate is associated with intraoperative reflex bradycardia in patients undergoing microlaryngoscopy (MLS) in general anesthesia.
The study will be conducted using the crossover randomized controlled method. Preterm infants who began oral feeding from the neonatal intensive care unit will be divided into two groups through randomization in the computer environment. Following the randomization, infants in Group 1 will be fed by applying ''elastic sac'' at the first feeding hour after they are included in the study and in the next feeding they will be fed without performing any application. Infants in Group 2 will be fed without performing any application at the first feeding hour after they are included in the study and they will be fed at the second feeding hour by applying ''elastic sac''. Infants in both groups will be fed by the researcher with a bottle in a semi-fowler right lateral position during feeding hours. During feeding, the effect of the elastic sac on the infant's feeding status and physiological parameters will be evaluated.
This study aims to compare the hemodynamic parameters within and between patients who received Protamine Sulfate (PS) with Hydrocortisone (HC) vs. Protamine Sulfate alone during cardiac surgeries.
The purpose of this study was to assess the effectiveness of Kangarooing small babies on the back of a mother
This is a prospective pivotal study in patients admitted/visiting the cardiology ward and/or outpatient clinics for various indications. The study will be conducted in two stages. The first stage will comprise a pilot study with 10 subjects, which will be completed and analyzed prior to initiation of the second stage. The two studies are independent and are included in the same protocol for logistical reasons. The second stage of the study, which will include 120 subjects, is pivotal and intended to validate the Gili BioSensor System. Testing procedure will include seating the subject in either a steady chair in front of a table, or in bed with the bedrest raised in front of a cardiac table (or similar). The subject will be seated for 5 minutes to reach a physiological steady state. During this time, the subject will be connected to the reference device according to the manufacturer's guidelines. The investigational device will be placed on a stable surface in front of the subject (table / cardiac table or similar) and will point to the left side of the subject's chest. Both the investigational and reference devices will be temporally synchronized to maintain coordinated recording. Following the 5-minute resting period, both investigational and reference devices will be activated for a comparative recording session to acquire at least 180 seconds (3 minutes) of evaluable data. Each 60-sec interval will be used separately for comparative analyses.
Febrile infants younger than 3 months old present a diagnostic dilemma to the emergency physician. Tension remains between the need for early aggressive intervention among patients with suspected sepsis and the global phenomena of increasing antibiotic resistance. The investigators aim to: (1) To study the association between heart rate variability (HRV) and the presence of a serious infection (SI) among infants younger than 3 months old. The investigators hypothesize that a reduced HRV is associated with the presence of SI. (2) To compare HRV between febrile infants < 3 months with non-febrile infants. The investigators hypothesize that the variability will be reduced in febrile infants with SIs when compared to non-febrile well infants, but not among febrile infants without SIs when compared to non-febrile well infants. (3) To study if HRV will provide incremental diagnostic information over current triage tools.
Transcutaneous electric nerve stimulation (TENS) is widely used for the treatment of adhesive capsulitis, nevertheless, its potential impact on heart physiology has not been well established. The investigator explored if TENS at shoulder region affect heart rhythm and the machinery involved. Subjects were stratified into groups received sham stimulation (TENS-S) and TENS on either the right (TENS-R) or left (TENS-L) shoulder. A built-in waveform for treating adhesive capsulitis with a maximal tolerable intensity below the pain threshold was applied to subjects form a commercial TENS equipment for 5 min. The electrocardiogram (ECG) and heart rate (HR) were continuously recorded and the ECG was off-line transferred into power spectrum for analysis.
