Recovery Time

In this study, the investigators want to examine the effects of intravenous anesthetic drugs and gases on cognitive functions in the postoperative period in individuals who will undergo surgery for obesity. The investigators believe that the anesthesia method we apply with inhalation gases is also as reliable method as total intravenous anesthesia for postoperative cognitive functions in these patients who undergoe sleeve gastrectomy. The anesthesia method applied intravenously and with inahalational gases have been applied safely for many years. Comparisons between these two anesthesia technics in obese individuals and for postoperative cognitive dysfunctions are limited. Studies on the examination of cognitive functions in postoperative patients have gained momentum with the use of neuropsychiatric tests performed on patients who have undergone cardiac surgery and these tests have also been performed on individuals who have undergone non-cardiac surgery. And yet, similar declines in cognitive functions have been observed. For these reasons, the effects of surgery itself and anesthesia methods on cognitive functions have been studied up to date. In this study, the investigators plan to evaluate patients who will undergo obesity surgery in both anesthesia methods by the recovery times from anesthesia and the residual effects of anesthesia, and after awakening they plan to evaluate their cognitive functions with neuropsychiatric tests that will be performed at certain intervals.

The most common imaging procedure requiring sedation/anesthesia for the pediatric population is magnetic resonance imaging (MRI). However, the optimal anesthetic/sedation plan has not been determined for these procedures. Historically, common medications have included the use of pentobarbital and propofol, but in 2015, publication in the New England Journal of Medicine highlighted the accumulating evidence for the possible neurotoxic effects of these types of anesthetics in animal models and a collection of epidemiologic studies in humans. Although these initial possibilities have since been proven as less of a concern, in the interim, data has shown that alternative sedative agents, such as dexmedetomidine, may not have the same neurotoxic effect and could possibly even provide neuroprotection. Dexmedetomidine also possesses other beneficial traits such as reducing risks of pulmonary atelectasis or upper airway collapse, typically found with the administration of propofol. A concern raised by previous studies has been the possibility that the addition of dexmedetomidine could increase recovery times, leading to disruptions in workflow. Although it has been shown that large doses of dexmedetomidine exposure may lead to longer PACU stays, it is uncertain whether a small dose of dexmedetomidine would have such a significant impact. Based on the investigators' pilot trial6, the investigators found that a bolus of 1 mcg/kg dose of dexmedetomidine with a bolus of titrated propofol of 2-3 mg/kg and an infusion of propofol of 100 mcg/kg/min provided adequate sedation for successful scans, reduced propofol (infusion) exposure by 60%, and did not significantly increase recovery times. Finally, there is a paucity in literature for studies examining a range of doses subsequently; often, a control group is compared to a single, self-selected dose of choice. Here, the investigators hope to provide a range of doses to minimize selection bias in our study design and determine the dose that would provide the optimal sedation for these scans and minimize excess anesthetic exposure.

Street running has become an increasingly popular sport. As a result, effective recovery strategies after exercise are essential. In this context, two techniques stand out: one already validated, active recovery (AR), and another with potential, blood flow restriction (BFR). This study aims to investigate whether using both techniques simultaneously can benefit practitioners and improve outcomes compared to complete rest.

This study aims to evaluate the efficacy of sublingual caffeine in reducing recovery time and incidence of postoperative agitation in elderly patients undergoing general anesthesia.

Resistance training has been widely performed due to its health benefits. However, performing this training at high intensity causes significant muscle stress, leading to fatigue and compromising performance. It is essential to implement effective recovery strategies to optimize physiological adaptations. Among the accessible techniques, blood flow restriction (BFR) has shown promise for its potential to accelerate muscle recovery.

In operating procedure with general anesthesia muscle relaxant is usually used to increase success rate of the operation and to give better outcome. The use of reversal drugs aims to reduce the risk of post-operative complications due to muscle relaxants. Neostigmine is commonly used as a reversal drug, but its indirect mechanism of action results in a long and unpredictable recovery time. Sugammadex directly bind and inactivate rocuronium, in which resulting in a faster and predictable recovery time. However, the high price limits the use of sugammadex. This study aims to compare the effect of half dose sugammadex and neostigmine against the moderate neuromuscular blockade of rocuronium. The main questions it aims to answer are: Does half dose sugammadex gives faster recovery time? Researchers will compare sugammadex to neostigmine to see if sugammadex gives faster recovery time. Participants will: Be given sugammadex or neostigmine as a reversal drug after the operation done
