a comparison of the effects of desflurane and tiva on antioxidant system in morbidly obese patients

Conditions: Oxidative Stress; Morbid Obesity

Summary: with the development of technology, the safety of anesthesia devices and the progression of monitoring techniques affect the anesthetic management. there are some disadvantages such as high cost of inhalation anesthetics and long postoperative recovery time. the effects of total intravenous anesthesia (tiva), which has been used for many years and whose positive aspects are well known, on antioxidant system in high risk patients such as morbid obese should be investigated. the aim of this study was to compare the effects of desflurane anesthesia and total intravenous anesthesia (tiva) on the antioxidant system in morbidly obese patients undergoing bariatric surgery.

obesity is a chronic disease that negatively affects the quality and duration of life. it is one of the most important health problem in the world and very common in turkey. morbid obesity operations have started to be performed frequently in our country with the effective results obtained with the continuation of weight loss after being widely applied in europe and the united states. in our country, with the increase of obesity, laparoscopic bariatric is preferred especially with low complication rates. inhalation anesthesia is still a major source of chemical hazard in the hospital environment due to the widespread use in operating rooms. factors affecting the presence of anesthetic gases in the environment; device leakage, ventilation, fresh gas flow and operation of the air wasting system. long-term exposure to anesthetic gases is known to adversely affect the health of the workers in the operating room. it has been shown that many anesthetic agents produce free radicals and alter serum antioxidant levels in patients. antioxidant enzymes clean free radicals. free radicals induced by various diseases can trigger oxidative stress and result in increased oxidative products. it was reported that particularly desflurane induced oxidative stress and increased oxidative products. at the same time, it was reported that desflurane triggered local and systemic oxidative stress in the experimental studies, but propofol had antioxidant properties. with the development of technology, the safety of anesthesia devices and the progression of monitoring techniques affect the anesthetic management. there are some disadvantages such as high cost of inhalation anesthetics and long postoperative recovery time. the effects of total intravenous anesthesia (tiva), which has been used for many years and whose positive aspects are well known, on antioxidant system in high risk patients such as morbid obese should be investigated. the aim of this study was to compare the effects of desflurane anesthesia and total intravenous anesthesia (tiva) on the antioxidant system in morbidly obese patients undergoing bariatric surgery.
