Retrospective Evaluation of Anesthesia Experience at a Training and Research Hospital in Turkey

This study aims to evaluate retrospectively the two-year data of our clinic concerning the effects of training for reduced fresh gas flow anesthesia applications, the demographic data of patients, the types of anesthesia performed, non-operating room anesthesia applications and the incidences of admission to the post-anesthesia care unit. Hospital archives on anesthesia services of 2016-2017 were scanned. The acquired data were analyzed retrospectively with yearly comparisons on the bases of the consumed amount of inhalation anesthetics, distribution of the peripheral blocks according to the surgical sections, the number of patients operated outside the operating room and sent to the post-anesthesia care unit. The number of operations carried out in our hospital was 22533 in 2016 and 24634 in 2017. High flow anesthesia in 2016 and low flow anesthesia in 2017 were found statistically high (P < 0.001). In 2016 and 2017, neuraxial block cases were used in 76.24% and 76.19% of the cesarean section, 4936and 7152 patients underwent anesthesia outside of the operating room; 405 and 816 patients were sent to the post-anesthesia care unit, respectively. In 2017, the consumption of inhalation agents decreased after regular training on the reduced fresh gas flow technique. In 2017, the increase observed in peripheral block applications was based on the increase in ultrasound experience in our clinic. We recommend a combination of reduced fresh gas flow with peripheral or neuraxial blocks to achieve multimodal general anesthesia.
