Filter by:Desflurane is increasingly used in general anesthesia. Its pharmacokinetic properties are known and its distribution is easily modeled. Yet these models fail in practice. In order to increase accuracy, any model should include cardiac output, alveolar ventilation and alveolar dead space, all of which are either hard to measure or impractical, at least. A previous study performed by the same investigator showed that time to target endtidal concentration of sevoflurane is prolonged with increased cardiac output, but only if the patient has increased muscle mass. Although desflurane has lower muscle and fat solubility, our observations suggest a similar prolongation in case of increased muscle mass. The investigators aim to investigate if patient characteristics such as gender, age, height, weight, body type prolongs time to reach target endtidal desflurane concentration in low flow anesthesia.
It is known that morbidly obese patients are often accompanied by cardiovascular complications such as hypertension, cardiac hypertrophy, and diastolic dysfunction, and are known to increase the risk of hypotension during anesthesia induction. Remimazolam is widely used in Japan and the United States, and it was approved as a drug for general anesthesia and sedation in Korea in 2021. It was reported that remimazolam caused less hypotension after induction of anesthesia than propofol. However, there is no study on the use of remimazolam in patients undergoing bariatric surgery due to morbid obesity. Therefore, through this study, we plan to check whether remimazolam is safe and effective as an anesthetic-inducing agent for morbidly obese patients undergoing bariatric surgery.
Biliary atresia is a serious congenital anomaly characterized by persistent and progressive cholestatic jaundice. The incidence of biliary atresia is more common in East Asia, especially China, with an incidence of 2 per 10,000 live births. Liver transplantation is the only effective way to treat end-stage liver disease. However, distant organ damage, affecting the heart, brain, kidneys, lungs, and intestines, is still an important factor affecting the long-term survival of children after surgery. Desflurane is a volatile anesthetic commonly used in surgery. In order to observe the effect of desflurane on the incidence of early postoperative pediatric acute respiratory distress syndrome (PARDS) with biliary atresia who underwent living donor liver transplantation, and explore the related mechanism, a total of 165 infant patients underwent living liver transplantation due to biliary atresia from March 2023 to October 2023 are included in our single-center prospective study. They are randomly divided into propofol group (n=55), propofol and desflurane group (n=55) and desflurane group (n=55) according to the difference of intraoperative anesthesia maintenance. Gender, age, height, weight, PELD scores and other preoperative basic data are recorded. Operation time, anhepatic time and intraoperative blood loss volume are recorded. The basic information of liver donors are also recorded. Postoperative mechanical ventilation time, ICU stay time, tacrolimus concentration, total length of hospital stay and mortality during hospitalization are recorded. According to the the definition of PARDS recommended by the 2015 Pediatric Acute Lung Injury Consensus Conference is used as the diagnostic and grading criteria for postoperative PARDS, and the incidence and grading of PARDS within the first seven days after surgery are evaluated in the three groups. Peripheral blood is collected immediately after anesthesia induction, 30min after reperfusion and at the end of surgery to detect serum levels of HMGB1, IL-6 and TNF-α by enzyme linked immunosorbent assay (ELISA).
Subthalamic nucleus (STN)-deep brain stimulation (DBS) under general anesthesia has been applied to PD patients who cannot tolerate awake surgery, but general anesthesia will affect the electrical signal in microelectrode recording (MER) to some degree. This study is a prospective randomized controlled, noninferiority study, open label, endpoint outcome evaluator blinded, two-arm study. Parkinson's disease patients undergoing STN-DBS are randomly divided into a conscious sedation group (dexmedetomidine) and a general anesthesia group (desflurane). Normalized root mean square (NRMS) is used to compare the difference of neuronal activity between the two groups. The primary outcome is the percentage of high NRMS recorded by the MER signal (with the average NRMS recorded by MER after entering the STN greater than 2.0). The secondary outcomes are the NRMS, length of the STN, number of MER tracks, and differences in clinical outcomes 6 months after the operation.
In the present work the investigators will study the accuracy of the MAAS (Minimal-flow Autocontrol Anesthesia System) method to estimate the percentage of halogenated anesthetic (HA) to be supplied to the anesthetic circuit based on the estimation of HA uptake during the maintenance phase. The investigators will evaluate the accuracy of sevoflurane and desflurane vaporizers to guarantee the administration of that amount of estimated HA, thus guaranteeing the maintenance of the target concentration of HA at the end of expiration: end-tidal target HA% (ettHA%). To do this, the investigators will quantify the number of adjustments that need to be made to each vaporizer to maintain ettHA%. As secondary objectives, the investigators will analyze the time to reach the target concentration of HA, the deviations that occur from that concentration despite the correct application of the method, and the consumption of HA during the procedure. Through the entire procedure, all participants will be ventilated under a tailored open lung approach (tOLA) strategy.
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).
The primary aim of this study is to compare the effects of sevoflurane and desflurane on the QT interval. The secondary aim of this study is to compare the effects of drugs used in the induction and maintenance of anesthesia on the QT interval by calculating the Bazzet formula and iCEB.
This study intends to investigate the effects of desflurane on postoperative sleep quality to guide perioperative patient management.
During coronary artery bypass grafting (CABG) operations with cardiopulmonary bypass (CPB), the use of desflurane continuously or intermittently may have effects on serum brain natriuretic peptide (BNP) levels. The aim is to investigate the association between desflurane, serum BNP values, and clinical outcomes during CABG operations. In a prospective, randomized, double-blinded study, desflurane inhalational anesthesia was administered either continuously or intermittently (Group 1; n=60 versus Group 2; n=62). The preoperative and postoperative BNP levels at 24, 48 and 72 hours after surgery were collected. Outcomes were recorded.
Many factors during laparascopic surgery leads to PONV (postoperative nausea and vomiting), such as C02 insufflations causing peritoneal stretch and irritation and type of anaesthesia given during surgery. The two anesthetic techniques used in bariatric surgery are gas anesthesia (Remifentanil TCI and Desfluran) and Total Intra Venous Anesthesia (TIVA) with propofol. There are studies which have shown a reduction in postoperative nausea and vomiting following TIVA, and there are publications showing no statistically significant difference. The aim of this study was to investigate the best anaesthetic approach for obese subjects, evaluating awakening time, postoperative nausea and pain. Our hypothesis was based on the fact that Propofol is a lipid-soluble anesthetic and therefore might have a prolonged effect in obese patients, leading to a longer awakening time along with postoperative nausea and vomiting. This hypothesis is also described earlier by obese patients have more depots (bulk fat) and also more fat surface making anaesthetics storage more easier, and also that the anesthetic will return into the circulation when the administration is stopped [18].
