Filter by:The aim of the present study is to compare between general anesthesia versus sedation with dexmedetomidine and ketamine with local infilteration at the catheter insertion site in pediatric patients undergoing transcutaneous closure of atrial septal defect on hemodynamic changes.
General anesthesia is characterized by temporary loss of consciousness and decreased reflex activity without any change in vital functions. It can be performed with intravenous and/or inhalation agents. During general anesthesia, breathing is stopped and respiratory support is provided to patients with various respiratory equipment and ventilation modes on the anesthesia device. The most commonly used ventilation modes during anesthesia are volume controlled (VCV) and pressure controlled (PCV). In pressure-controlled ventilation, ventilation is provided with the airway pressure determined by the anesthesiologist throughout inspiration. While the pressure is constant during inspiration, the tidal volume is variable. In volume controlled ventilation, ventilation executed at the volume is set by the anesthesiologist. In other words, the determined volume is constant, but airway pressures vary. In pediatric anesthesia practice modes have not been shown to have a clear advantage over each other. Both modes have advantages and disadvantages. With the development of modern anesthesia devices in recent years, safe ventilation can be provided even in very young children with volume controlled mode (VCV). Atelectasis is the restriction of gas exchange due to complete or partial collapse of the lung. Atelectasis can be seen in 90 percent of patients receiving general anesthesia. This incidence is reported to be 68-100 percent in children. Lung ultrasonography is an imaging method with many advantages for imaging lung-related diseases, such as not containing ionizing radiation, being inexpensive, and being performed at the bedside. Recently, its use by anesthesiologists has become widespread in many lung pathologies, including atelectasis. Traditional and modified lung ultrasonography scoring systems can be used to evaluate atelectasis in lung parenchyma with ultrasonography. In addition to the traditional system, modified scoring system also enables to evaluate small subpleural consolidations In this study, it was aimed to compare the effects of volume controlled and pressure controlled ventilation modes used in general anesthesia in children on atelectasis with lung ultrasonography.
In this study, the investigators compared spinal anesthesia under ketofol (ketamine-propofol combination) sedation with general anesthesia in terms of intraoperative and postoperative hemodynamics, respiratory parameters and cost in patients undergoing umbilical hernia operation. the investigator aimed to provide the most appropriate and hemodynamically stable option for the patient, to decrease the complication rates and to reduce the associated costs.
To compare the effects of total intravenous anesthesia and inhalation anesthesia used for maintenance on postoperative recovery in patients undergoing septorhinoplasty surgery under general anesthesia, using the recovery quality score (QoR-40).
The correlations of deep brain nuclei firing and cerebral cortex activity during recovery from general anesthesia is unclear. In this study, the local field potential (LFP) from the deep brain nuclei and the scalp electroencephalogram (EEG) of the frontal cortex were recorded from patients undergoing deep brain stimulation (DBS) surgery during the recovery from general anesthesia, in order to explore the changes and relevance of deep brain nuclei firing and cortex activity during the recovery of consciousness from general anesthesia .
Without adequate monitoring, administration of anesthetic agents can create unnecessary deeper anesthetic plane in geriatric population. This study aims to compare the duration of deep hypnotic time (DHT) in geriatric patients undergoing general anesthesia with additional BIS monitor compared to standard monitoring. This study was a randomized clinical trial involving 44 geriatric patients undergoing general anesthesia. Subjects are divided into two groups, one with additional BISTM monitor and the other with standard monitoring. Data acquired from BISTM will continually be recorded to be analyzed afterward
The goal of this observational study is to assess whether the continuous non-invasive haemodynamic monitor MOH200 (measuring blood pressure as well as pulse rate) is effective or not in people undergoing general anesthetic surgeries for more than 60 minutes with planned invasive blood pressure and pulse oximeter monitoring. Researchers will compare blood pressure data derived from MOH200 to the invasive blood pressure (IBP) data to see if the MOH200 is effective to measure the blood pressure of a surgical person. Also, researchers will compare pulse rate data drived from MOH200 to that from the pulse oximeter to see if the MOH200 is effective to measure the pulse rate of a surgical person. Participants will be asked to be applied with MOH200 monitoring while IBP monitoring and pulse oximeter are applied. And after 30 minutes of the surgery, researchers will monitor the adverse effects occurred on the skin of participants to assess the safety of MOH200.
The aim of this study is to compare spinal and general anesthesia in neonates undergoing herniorrhaphy.
Esketamine group was induced with esketamine 0.5 mg/kg, propofol 2 mg/kg, and rocuronium bromide 0.9 mg/kg. Anesthesia is maintained with propofol 5 mg/kg/h and esketamine 0.5 mg/kg/h. Anesthesia induction in the opioid group Sufentanil 0.5 ug/kg, propofol 2 mg/kg, rocuronium bromide 0.9 mg/kg. Anesthesia is maintained with propofol 5 mg/kg/h and remifentanil 1 ug/kg/h.
This clinical trial aims to compare the effects of lidocaine, dexmedetomidine, esmolol, and magnesium on optic nerve sheath diameter and hemodynamic response to laryngoscopy. The participants will be patients determined to need intubation and general anesthesia for any elective surgery. Each participant will receive either lidocaine, dexmedetomidine, esmolol, magnesium, or none before anesthesia induction, according to randomization. The investigator will measure the optic nerve sheath diameter by ultrasonography before and after intubation. Researchers will compare the difference between optic nerve sheath diameter, systolic blood pressure, and heart rate before and after laryngoscopy and search for the most stable group. The trial aims to determine a general anesthesia induction protocol for patients sensitive to intracranial pressure changes reflected as optic nerve sheath diameter for easy monitoring.
