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.

NCT ID: NCT06254534 Recruiting - General Anesthesia Clinical Trials

Lidocaine, Dexmedetomidine, Esmolol and Magnesium Effect on Optic Nerve Sheath Diameter After Laryngoscopy

Start date: February 14, 2024
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06237504 Recruiting - Elderly Clinical Trials

The Clinical Efficacy of the Video Laryngeal Mask (SaCoVLM™) in Geriatric Patients: A Comparison With a Conventional Supraglottic Airway Device (Ambu®Auragain™)

Start date: February 2024
Phase: N/A
Study type: Interventional

This study aims to investigate whether the use of a video LMA device (SacoVLM™) will facilitate successful supraglottic airway device (SAD) insertion compared to the use of a conventional 2nd generation SAD (Ambu®Auragain™) in elderly patients. This study is a randomized trail with a 50% probability of being assigned to either group. Randomization will be done by an anesthesiologist not involved in anesthesia or postoperative outcome assessment. Patients and the investigator in charge of postoperative outcomes assessment will be blinded to group allocation.

NCT ID: NCT06099977 Recruiting - Prostate Cancer Clinical Trials

Binaural Sound for Remimazolam Induction

Start date: November 1, 2023
Phase: N/A
Study type: Interventional

It is important to decrease the time-to-loss of consciousness and anesthetics dose of remimazolam for general anesthesia induction. We will evaluate the effect of binaural sound for general anestheia induction using remimazolam infusion.

NCT ID: NCT06061159 Recruiting - General Anesthesia Clinical Trials

The ED95 of Single Intravenous Bolus Remimazolam Besylate in Pediatric Patients During General Anesthesia Induction

Start date: October 6, 2023
Phase: Phase 4
Study type: Interventional

Due to the incomplete development of systems and low pain thresholds in the pediatric population, good general anesthesia is required during the perioperative period to ensure the smooth progress of the surgery.Propofol is often used for anesthesia induction in clinical work, which can achieve good anesthesia effects. However, this drug has obvious injection pain and is prone to significant inhibition of blood circulation, and may even lead to adverse conditions such as respiratory depression in children. For the pediatric population, maintaining appropriate anesthesia depth and stable circulation during the induction period of general anesthesia has always been a focus of attention and research by anesthesiologists.Remimazolam besylate is a new type of water-soluble ultra short acting benzodiazepine drug that is hydrolyzed and metabolized by plasma esterase in the body, independent of liver and kidney function, and the metabolite zolam propionic acid has no pharmacological activity; Rapid onset and failure, short sedation recovery time; Has little impact on respiration and circulation; And there is no injection pain.Remazolam besylate is highly suitable for children due to its characteristics, and some studies have demonstrated the safety of intravenous injection of Remazolam besylate. However, there is limited research on its dosage exploration, which to some extent limits its clinical application in children.This study aims to explore the 95% effective dose (ED95) of single intravenous injection of remidazolam besylate in children of different age groups, providing a theoretical basis for the use of remidazolam besylate in pediatric anesthesia.

NCT ID: NCT06059248 Recruiting - General Anesthesia Clinical Trials

Effect of Different Head Positions During Endotracheal Intubation on Postoperative Sore Throat

Start date: April 1, 2023
Phase: N/A
Study type: Interventional

The goal of this [ randomized clinical trial] is to [effect of different head positions on the incidence of postoperative sore throat ] in [patients with endotracheal intubation ]. The main question it aims to answer is: the rate of postoperative sore throat will be reduced or not with the patients' head position changed during intubation.

NCT ID: NCT06056401 Completed - Clinical trials for Mechanical Ventilation

Comparison of Volume-controlled and Pressure-controlled Ventilation in Clasp-knife Position

Start date: October 15, 2022
Phase: N/A
Study type: Interventional

Carbon dioxide (CO2) pneumoperitoneum and clasp-knife positioning are commonly used to improve surgical access during robot-assisted laparoscopic urological surgery. However, these methods are sometimes associated with several unwanted cardiopulmonary effects such as increased mean arterial pressure, decreased pulmonary compliance and functional residual capacity, increased peak inspiratory pressure, and respiratory acidosis in association with hypercarbia. Volume-controlled ventilation (VCV) is the most commonly used method of ventilation during general anesthesia. It provides fixed minute ventilation and pulmonary resistance, which affect airway pressure. In pressure-controlled ventilation (PCV), constant inspiratory airway pressure can be achieved by decelerating the flow. However, minute ventilation is not fixed . CO2 pneumoperitoneum in the clasp-knife positioning can influence hemodynamic variables, including blood pressure, heart rate, and cardiac output. This is because changes in airway pressure affect intrathoracic pressure and the function of the heart itself. In this randomized study, we investigated the effects of VCV and PCV on peak inspiratory pressure during robot-assisted laparoscopic urological surgery involving CO2 pneumoperitoneum in the clasp-knife position.

NCT ID: NCT06030063 Recruiting - General Anesthesia Clinical Trials

NCT ID: NCT05952050 Recruiting - General Anesthesia Clinical Trials

Different Administration Routes of Dexmedetomidine on Postoperative Delirium

Start date: August 1, 2023
Phase: N/A
Study type: Interventional

Intravenous dexmedetomidine has been reported to decrease the occurrence of postoperative delirium (POD) in elderly patients. Nevertheless, some previous studies have indicated that intratracheal dexmedetomidine and intranasal dexmedetomidine are also effective and convenient. The current study aimed to compare the effect of different administration routes of dexmedetomidine on POD in elderly patients.
