ABSTRACT

Increasing competitive pressure and health performance system in the hospitals result in pressure to reduce the resources allocated. The aim of this study was to evaluate the anesthesiology and intensive care physicians awareness of the cost of the materials used and to determine the factors that influence it. This survey was conducted between September 2012 and September 2013 after the approval of the local ethics committee. Overall 149 anesthetists were included in the study. Participants were asked to estimate the cost of 30 products used by anesthesiology and intensive care units. One hundred forty nine doctors, 45% female and 55% male, participated frthis study. Of the total 30 questions the averages of cost estimations were 5.8% accurate estimation, 35.13% underestimation and 59.16% overestimation. When the participants were divided into the different groups of institution, duration of working in this profession and sex, there were no statistically significant differences regarding accurate estimation. However, there was statistically significant difference in underestimation. In underestimation, there was no significant difference between 16-20 year group and >20 year group but these two groups have more price overestimation than the other groups [p=0.031]. Furthermore, when all the participants were evaluated there were no significant difference between age-accurate cost estimation and profession time-accurate cost estimation. Anesthesiology and intensive care physicians in this survey have an insufficient awareness of the cost of the drugs and materials that they use. The institution and experience are not effective factors for accurate estimate. Programs for improving the health workers knowledge creating awareness of cost should be planned in order to use the resources more efficiently and cost effectively

ABSTRACT

Anesthesia and surgical intervention, leads to the development of systemic inflammatory response. The severity of the inflammatory response depends on the pharmacological effects of anesthetic agents and duration of anesthesia. Objective of the study was to investigate the effect of nitrous oxide on VEGF and VEGFR1 levels in patients undergoing surgery. Forty-four patients undergoing elective urological surgery were included in the study. Anesthesia maintenance was provided with 1-2 MAC sevoflurane, O[2] 50%, N[2]O 50% in 4L/m transporter gase for group 1 [n=22] and 1-2 MAC sevoflurane, O[2] 50%, air 50% in 4L/m transporter gase for group 2 [n=22] Venous blood samples for the measurement of VEGF and VEGFR1 were taken before the induction of anaesthesia, 60 minutes of anesthesia induction, at the end of anaesthesia and 24 hours after operation. In statistical analysis Bonferroni test and analysis of variance at the repeated measures were used In the postoperative period serum VEGF levels had decreased significantly in both group whereas VEGFR1 did not show a significant change. Nitrous oxide showed significant effect on angiogenic parameters. Further detailed studies are required to evaluate the effect of nitrous oxide
