compare the time of second hypotension after administration of three different doses of ephedrine 5,10,15 mg
The investigators will conduct a 12,500-patient randomized multi-center trial to determine (i) which general anesthesia technique yields superior patient recovery experiences in any of three surgical categories ((a) major inpatient surgery, (b) minor inpatient surgery, (c) outpatient surgery) and (ii) whether TIVA confers no more than a small (0.2 %) increased risk of intraoperative awareness than INVA in patients undergoing both outpatient and inpatient surgeries
Remimazolam has demonstrated the potential as a valuable medication for procedural sedation and general anesthesia. However, the effective dosage of remimazolam in pediatric patients is still unknown.
The purpose of this study is to assess the feasibility of SafeLM as a primary airway device and as a conduit for intubation with and without the use of a bougie
ıntroduction Pulmonary aspiration under general anesthesia is a rare but serious complication in healthy patients undergoing elective surgery. In the preoperative period, negative metabolic, physiological, and/or psychological consequences may occur due to prolonged hunger time (1). It is important to shorten the preoperative fasting period to reduce anxiety and hunger, especially in pediatric patients (2). Material-Methods This study at Bursa Uludag University Hospital (January 2021- January 2022) involved 84 ASA (American Society of Anesthesiologists) class I-III patients aged 4-11 years undergoing elective urogenital surgery, with certain exclusions like gastrointestinal disorders and high BMI (Body Mass Index). Gastric antral area (GAA) was measured with ultrasound (USG) before liquid intake and at various intervals there after; 5, 10, 30, 60, 90 minutes. Patients were split into four groups based on liquid (water or apple juice) and activity level (rest or mobilization). Resting patients watched animations, while mobilized patients were encouraged to walk.
Frailty is a multidimensional syndrome characterized by a decline in physiological homeostatic reserve, which translates into an increased susceptibility to adverse events and unfavorable outcomes following even small exposures to physical, physiological or psychosocial stress. In the European population up to 69 years, the prevalence is generally 6,5%, beyond 85 years of age it exceeds 50% and reaches 65% in the over-ninety population. The prevalence of frailty in the surgical population varies, depending on the studies, from 10 to 40%. Frailty and its severity grade represent themselves noticeably as strong predictors of adverse postoperative outcomes. The strongest evidence of association is recorded between frailty and mortality at 30 days. The purpose of this study is to describe the characteristics of patients undergoing anesthesia for cardiothoracic and vascular surgery, with a specific focus on frailty elements and associated comorbidities that necessitate surgery. This data analysis will provide valuable insights into the interaction between frailty, multimorbidity, and the perioperative pathway of patients undergoing cardiothoracic and vascular anesthesia.
Mentorship is increasingly recognised as a core component of career advancement, medical education and psychosocial support. Mentorship is defined as the relationship between a mentor and a mentee, where both collegially gain from an open and active relationship Overall, there is little known about mentorship in anaesthesia. To our knowledge, no study has yet explored the fostering of an anaesthetic mentor-mentee relationship from the point of view of the mentor and mentee themselves. Preferences with regards to implementation programs versus free choice and the importance of sociodemographic characteristics (gender, ethnicity, sexuality, disability, age) have also yet to be investigated. The prevalence of mentor-mentee relationships/ the understanding of mentor and mentee choice in anaesthesia will be studied. In parallel, key socio-demographics that are linked to the choice of mentor-mentee, as well as evaluate availability of mentors, and other barriers to finding mentorship will also be investigated. Hypothesis: mentorship might be affected by demographics such as gender, age, ethnicity, working country, experience, academia and subspecialty.
Ultrasound-guided regional anesthesia/analgesia techniques (or simply, 'regional blocks') have gained popularity as they can reduce, and sometimes even eliminate, the need for opiate analgesics (and, consequently, their side effects), thereby improving patient safety, reducing length of hospital stay and medical costs, and improving patient satisfaction. However, a major barrier to mainstream uptake of such techniques relates to training. These techniques require the acquisition of new skills under expert guidance, which is often not possible given the daily demands placed upon anesthesiologists. As a result, many opportunities for providing regional blocks may be missed. The purpose of this study is to implement a new real-time 'near remote' guidance method in which trainees who are to perform regional blocks can do so via tele-mentoring under expert guidance. This will be done using a novel technology whereby the ultrasound image is concurrently displayed on an iPad screen (for the block operator/trainee) as well as on the (near remotely supervising) expert mentor's smartphone. Trainees and mentors will use this method to perform various standard of care regional blocks, either in the perioperative or emergency department settings. Participants' opinions of the novel teaching and learning method will be assessed.
Total intravenous anaesthesia (TIVA) is now a preferred technique for providing general anaesthesia (GA) because of its various inherent advantages like reduced postoperative nausea and vomiting (PONV), improved quality of post-operative recovery, anti-inflammatory and antioxidant action, anti-neoplastic activity, analgesic action, and absence of greenhouse effect. The evolution and advancement in automated anaesthesia delivery systems particularly for propofol have made propofol-TIVA more efficient by removing the human interface for both rate and concentration adjustments. Automated computer-controlled closed loop anaesthesia device adjusts propofol delivery based on patient's frontal cortex electrical activity determined by bispectral index (BIS). Closed loop anaesthesia delivery system (CLADS) is an indigenously developed patented (Patent no.502/DEL/2003 & US 9,108,013 B2) computer-controlled anaesthesia delivery system which works with feedback loop information elicited by BIS monitoring and delivers propofol TIVA to the patient via a non-TCI automated infusion pump. It has been an extensively used and validated in patients undergoing both cardiac and non-cardiac surgical procedures. A new compact and upgraded version of CLADS is now available. This new version incorporates the anesthetic depth monitor, hemodynamic monitor, controller, user interface and actuator syringe pump into a single, compact and user-friendly module. The investigators aim to conduct a prospective randomized pilot study comparing the new CLADS and older CLADS version with respect to: adequacy of anaesthesia depth maintenance, performance characteristic of propofol delivery system, propofol requirement, haemodynamics stability, recovery from anesthesia and postoperative sedation.
