Filter by: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
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.
The Aim of the study was to determine the impact of the videolaryngoscpe on the time needed to intubate. This was a Prospective, randomized, simple blinded study. The participants intubated patients for surgery under general anesthesia either with direct laryngoscpy or with videolaryngoscopy.
Hemodynamic changes during induction of anesthesia may have adverse outcomes and should therefore be avoided. The decrease in blood pressure during induction of anesthesia with propofol is due to a decrease in systemic vascular resistance or cardiac output and may be increased by the concomitant use of other drugs such as remifentanil. Target controlled infusion (TCI) system aims to reach the theoretically targeted blood or brain concentration of anesthetic agents based on the patient's age, weight, and height, with computer-assisted algorithms. In manual anesthesia induction, anesthetic agents are administered at a fixed dose and rate adjusted according to the patient's weight, which may cause hypotension in patients with low cardiovascular performance. As target-controlled infusion (TCI) obviates the need to calculate the infusion rate manually, the use of TCI may provide a better hemodynamic profile during anesthesia induction This study was designed to test the hypothesis that propofol by TCI anesthesia induction is associated with a lower hypotension rate when compared with manual anesthesia induction
In our study, it was aimed to show the contribution of intraoperative intravenous magnesium sulfate administration to peroperative opioid consumption and postoperative analgesia.
Part 1: To determine the doses of IV HSK3486 and propofol for use in Part 2, the abuse potential part of the study. Part 2: To evaluate the abuse potential of HSK3486 compared with propofol when administered IV to healthy nondependent, recreational CNS depressant drug users.
Videolaryngoscopy-guided intubation has become widespread as a means of preventing major complications relating to airway management by improving the glottic view, increasing the first attempt success rate, likely reduce rates of hypoxemic events, while reducing the rate of airway trauma. However, as randomized controlled studies in patients with anticipated difficult intubation undergoing ear nose and throat (ENT) or oral and maxillofacial (OMF) surgery are lacking, it is still unknown if hyperangulated blades improve glottic view and if their use translates into faster intubation. The primary aim of this randomized controlled trial is to compare the percentage of glottic opening (POGO) between hyperangulated blades and Macintosh blades in patients with expected difficult intubation undergoing ENT or OMF surgery who require transoral tracheal intubation. Secondary aims are to compare secondary outcome measures such as time variables, indicators for difficult and successful intubation, number of attempts, view conditions, difficult airway classifications and adverse events between both blade types.
In anesthesia for ablation for cardiac arrhythmias, abrupt hemodynamic changes or fatal arrhythmias can be seen frequently. Remimazolam is a novel ultra-short acting benzodiazepine that provides good hemodynamic stability compared to conventional anesthetic agents. This study aims to investigate whether remimazolam reduces vasoactive agent use during cryo/radiofrequancy ablation under general anesthesia, compared to desflurane(RCT).
To demonstrate HSK3486 0.4/0.2 mg/kg (0.4 mg/kg intravenous [IV] slow injection over 30 [±5] seconds for the first dose, an additional 0.2 mg/kg if needed) is non-inferior to propofol 2.0/1.0 mg/kg (2.0 mg/kg IV slow injection over 30 [±5] seconds for first dose, an additional 1.0 mg/kg if needed) in success of induction of general anesthesia in adults undergoing elective surgery.
The aim of this study is to prove feasibility and assess the diagnostic performance of a machine learning algorithm that relies on data from 3D-face scans with predefined motion-sequences and scenes (MASCAN algorithm), together with patient-specific meta-data for the prediction of difficult mask ventilation. A secondary aim of the study is to verify whether voice and breathing scans improve the performance of the algorithm. From the clinical point of view, we believe that an automated assessment would be beneficial, as it preserves time and health-care resources while acting observer-independent, thus providing a rational, reproducible risk estimation.
