The objective of this single-blinded randomized controlled interventional clinical trial is to learn about the efficacy and long-term safety of etomidate compared to propofol as an anesthesia induction agent in patients undergoing coronary artery bypass graft (CABG) surgery. The primary aim of this study is to determine whether patients receiving etomidate or propofol exhibit similar requirements for vasopressor or ionotropic agents during both the intraoperative and postoperative periods. To achieve this goal, participants who are scheduled for CABG surgery will be randomly assigned to receive either etomidate or propofol as the principal hypnotic agent. The researchers will then compare the effects of these two anesthesia induction agents on various factors, including the need for hemodynamic support, hemodynamic stability, duration of mechanical ventilation, length of stay in the intensive care unit (ICU), and overall hospital length of stay. Additionally, they will assess whether there are disparities in mortality rates and readmission rates within a 6-month timeframe after the surgery. By comparing the outcomes between the two groups, the study aims to provide valuable insights into the potential differences in vasopressor or ionotropic agent requirements between etomidate and propofol. This information can help inform clinical decision-making and potentially optimize anesthesia management strategies for patients undergoing CABG surgery.

The aim of this study is to investigate the effectiveness of using a video laryngeal mask for airway management in patients undergoing laparoscopic cholecystectomy.
Elderly patients are frequently burdened with age-associated comorbidities and frailty, accompanied by physiological changes such as vascular stiffening, cardiac dysfunction, and impaired autonomic regulation. These factors not only increase the risk of adverse perioperative outcomes but also heighten sensitivity to anesthetic agents, making elderly patients particularly susceptible to anesthesia-related complications, especially hypotension. Consequently, optimizing anesthesia strategies for this high-risk population has become a critical goal in perioperative management. Titrated anesthesia, which individualizes anesthetic drug delivery based on patient response to achieve predefined endpoints, offers a potential approach to mitigating anesthetic risks. Ciprofol, a novel intravenous anesthetic, has been associated with less hemodynamic suppression compared with traditional agents; however, higher single doses may still predispose patients to hypotension. Remifentanil, an ultra-short-acting opioid, exerts significant cardiovascular depressive effects, further contributing to perioperative hypotension. It is hypothesized that titrated administration of anesthetic agents during both the induction and maintenance phases, compared with conventional fixed-dose protocols, may reduce the incidence of perioperative hypotension in elderly patients.
For patients after surgery, quality of recovery has significant impacts on the prognosis, quality of life, and rational allocation of medical resources. Dexmedetomidine and esketamine have each been used during the perioperative period and improved postoperative analgesia and subjective sleep quality. This 2x2 factorial trial is designed to explore the effects of dexmedetomidine, esketamine, and their combination on the quality of recovery in patients recovering from surgery under general anesthesia.
This multicenter, cluster-randomized, cluster-crossover clinical trial evaluates the impact of three intraoperative FiO2 (Fraction of Inspired Oxygen) oxygenation strategies-lower (FiO₂ 0.21-0.40), intermediate (FiO₂ 0.40-0.80), and higher (FiO₂ 0.80-1.00)-on postoperative organ injury and mortality in adult surgical patients. The trial aims to determine the optimal oxygenation strategy to improve perioperative outcomes.
Dexmedetomidine, an alpha-2 adrenergic agonist, has been shown to provide several benefits during endotracheal intubation: 1. \_Reduced anxiety and stress\_: Dexmedetomidine's anxiolytic and sedative effects help reduce anxiety and stress associated with endotracheal intubation. 2. \_Improved intubating conditions\_: Dexmedetomidine can improve intubating conditions by reducing the incidence of coughing, bucking, and laryngospasm. 3. \_Decreased hemodynamic responses\_: Dexmedetomidine can attenuate the hemodynamic responses to intubation, including tachycardia, hypertension, and increased cardiac output. 4. \_Increased ease of intubation\_: Dexmedetomidine can facilitate smoother and easier intubation by reducing the need for additional anesthetics or muscle relaxants. The physiological responses to dexmedetomidine during intubation include: 1. \_Decreased heart rate\_: Dexmedetomidine can cause a decrease in heart rate due to its effects on the sympathetic nervous system. 2. \_Decreased blood pressure\_: Dexmedetomidine can also cause a decrease in blood pressure due to its vasodilatory effects. 3. \_Increased sedation\_: Dexmedetomidine's sedative effects can help reduce anxiety and stress during intubation. 4. \_Reduced respiratory rate\_: Dexmedetomidine can cause a decrease in respiratory rate due to its effects on the respiratory centers in the brain. The clinical benefits of dexmedetomidine during intubation include: 1. \_Improved patient comfort\_: Dexmedetomidine's sedative and anxiolytic effects can improve patient comfort during intubation. 2. \_Reduced need for additional anesthetics\_: Dexmedetomidine can reduce the need for additional anesthetics or muscle relaxants during intubation. 3. \_Decreased risk of complications\_: Dexmedetomidine's effects on hemodynamic responses and respiratory rate can decrease the risk of complications during intubation.
The purpose of the study is to evaluate the relationship between perioperative electroencephalogram and emergence agitation in the nasal surgery. Previous studies showed that low frequency band wave activity increased during emergence delirium in pediatric patients. It is still not enough to explain the relationship between emergence agitation and electroencephalogram in adults. Researchers will demonstrate the relationship between parameters related electroencephalogram and emergence agitation in adults undergoing nasal surgery.
The study will enroll adult patients scheduled for elective surgery requiring general anesthesia. Participants will be randomly assigned to receive either HRS-9190 for Injection or Rocuronium. The primary objective is to measure the duration from the last dose of the study drug until the recovery of neuromuscular function to a specific level (TOFr ≥ 90%). Secondary objectives include evaluating the onset time and duration of action following each dose, the total time adequate muscle relaxation is maintained during surgery, and the detailed pattern of neuromuscular recovery. Safety assessments will include monitoring of adverse events, vital signs, laboratory parameters, and other safety indicators throughout the study period. The hypothesis of this study is that HRS-9190 for Injection could provide effective neuromuscular relaxation, with a satisfied safety profile in the target patient population.
This study aims to determine whether goal-directed analgesia using ANI(Analgesia/Nociception Index) can improve the quality of postoperative recovery in patients undergoing maxillofacial surgery.
This study aims to assess the accuracy, repeatability, and reproducibility of preoperative evaluation of Inferior Vena Cava (IVC) collapsibility index and caval aorta index for prediction of hypotension after induction of general anesthesia.
Laparoscopic cholecystectomy is still considered the gold standard for the surgical management of gallbladder disease due to its minimally invasive nature, shorter recovery time, and reduced postoperative complications. Despite these advantages, patients frequently experience moderate to severe postoperative pain, particularly in the early postoperative period, which can impede recovery, delay mobilization, and increase opioid consumption. Excessive opioid use after laparoscopic cholecystectomy is associated with several drawbacks, including nausea, vomiting, sedation, and delayed recovery. It also increases the risk of respiratory depression, especially in vulnerable patients, and may contribute to long-term opioid dependence. These risks highlight the importance of opioid-sparing strategies such as regional anesthesia techniques to improve patient outcomes and enhance recovery. Regional anesthesia techniques have emerged as essential components of multimodal analgesia strategies in abdominal surgeries. Among them, the Erector Spinae Plane (ESP) Block has gained popularity due to its relative ease of administration and favorable safety profile. Recently, a novel fascial plane block known as the EXORA block has been introduced as a promising alternative for abdominal wall analgesia. This block, which targets a different anatomical plane, is postulated to provide comparable or superior analgesic efficacy to traditional methods while maintaining safety and simplicity in execution. Given the ongoing pursuit of optimal analgesia with minimal side effects, it is essential to compare emerging techniques, such as the EXORA block, with established methods like the ESP block. The authors hypothesize that the EXORA and the ESP blocks provide superior postoperative analgesia compared to controls in the anterolateral abdomen in patients undergoing laparoscopic cholecystectomy and that the EXORA block analgesic profile is comparable to that of the ESP block.
The aim of this study is to compare the quality of recovery in patients undergoing arthroscopic shoulder surgery depending on the type of anesthesia used: 1. general anesthesia with preoperative brachial plexus block for intra- and postoperative analgesia 2. regional anesthesia (brachial plexus block) with intraoperative sedation.
Effective respiratory ventilation is achieved by moving the right amount of air in and out of the lungs while keeping the pressures at a safe level. A disposable safety device, Adult Sotair®, was created to improve manual ventilation delivery. In this non-inferiority study, we will perform a pre-post study design (single group, within-group comparison) to test the non-inferiority of the Adult Sotair® device compared to mechanical ventilation.
The goal of this observational study is to evaluate the effect of neonatal delivery time on umbilical cord blood gas parameters in pregnant women undergoing elective cesarean section under general or spinal anesthesia. The study population consists of adult pregnant women aged 18-40 years with singleton term pregnancies scheduled for elective cesarean delivery. The main questions it aims to answer are: Is neonatal delivery time associated with changes in umbilical artery pH values under general and spinal anesthesia? Is neonatal delivery time associated with changes in umbilical artery base excess under general and spinal anesthesia? Researchers will compare cesarean sections performed under general anesthesia with those performed under spinal anesthesia to determine whether the relationship between delivery time and umbilical cord blood gas parameters differs between anesthesia techniques. Participants will: Undergo elective cesarean delivery under general or spinal anesthesia as part of routine clinical care Have neonatal delivery time recorded intraoperatively Have umbilical artery blood gas parameters (pH and base excess) measured immediately after birth as part of standard neonatal assessment
In this observational study, we will assess cFT by Carotid ultrasound and IVC collapsibility index for prediction of hypotension after induction of general anesthesia in geriatric patients undergoing elective surgery.
The purpose of this study is to investigate the impact of supraphysiologic oxygen (hyperoxia) on myocardial function in anaesthetized patients undergoing non-cardiac vascular surgery.
Throat packs are commonly used in many surgical procedures involving the oral cavity and pharynx, primarily to prevent blood, saliva, and other debris from entering the lower respiratory tract, thereby maintaining a clear airway and reducing the risk of aspiration and respiratory complications. Traditionally, these packs are moistened with saline or used in a dry state, with the choice often depending on the surgeon's preference and specific surgical requirements. However, despite their widespread usage, the exploration of alternative substances to moisten throat packs, particularly those with additional therapeutic benefits, remains limited in medical research. This pilot study introduces Gengigel spray as an innovative alternative to saline for moistening throat packs. Gengigel, a hyaluronic acid (HA)-based product, is known for its healing properties and anti-inflammatory effects, which are beneficial in oral care. Gengigel provides a non-anesthetic approach that promotes tissue repair and reduces inflammation. This makes it particularly advantageous in the context of surgical procedures where reducing postoperative inflammation and promoting mucosal healing are crucial.
Post-operative delirium (POD) is known to be independently associated with pre-operative frailty, pre-operative cognitive status and per-operative ElectroEncephaloGram (EEG). However, no study has focused on the impact of these pre- and peri-operative outcomes on the prediction of Post-operative delirium (POD). Therefore, this study has been designed to assess the performance of a new score that includes pre-operative frailty, and per-operative ElectroEncephaloGram (EEG) in predicting post-operative delirium.
