Anesthetics

We have developed computer software to store data on all anesthetics administered by our department. Our residents transcribe data from the anesthetic records into the computer file, which is then available for producing monthly reports of method, agent, age, and duration statistics. Also another back up floppy disk is made for yearly statistics. Capacity of a floppy disk is 3000 cases of records in a month and 30000 cases in a year. It imposes little additional workload on our clinical personnel, who use simple codes to cumulation and analyze anesthetic records monthly with emphasis on minimal cost, accuracy of data and economy of time.

PURPOSE: To compare changes in human central corneal thickness after instillation of proparacaine with those after oxybuprocaine instillation, over a period of 10 minutes. METHODS: Eighteen healthy young participants were recruited. Baseline central corneal thicknesses were measured every 30 seconds for 10 minutes using a noncontact specular microscope. Changes in central corneal thickness were measured every 20 seconds for 10 minutes after the administration of one drop of 0.5% proparacaine into the right eye, and one drop of 0.4% oxybuprocaine into the left eye. RESULTS: Mean baseline central corneal thickness was 531 +/- 45 micrometer in the right eye and 531 +/- 42 micrometer in the left. The central corneal thickness after proparacaine instillation increased to 8.6 micrometer (4.5-12.6 micrometer, 95% CI) and then returned to baseline within 80 seconds. Central corneal thickness after oxybuprocaine instillation increased to 7.7 micrometer (3.6-11.2 micrometer, 95% CI) and then returned to baseline within 80 seconds. There was a second transient increase about 5 minute after proparacaine instillation but no additional transient increase after oxybuprocaine instillation. CONCLUSIONS: The severity of oxybuprocaine's effect on central corneal thickness is similar to that of proparacaine. Central corneal thickness instability may occur for 5 minutes after proparacaine administration. Therefore, changes in central corneal thickness after topical anesthetics instillation should be considered when measuring central corneal thickness.

BACKGROUND: One way to make rapid increase in alveolar anesthetic concentration includes using high fresh gas flow rates. Fresh gas flow rates should be increased to compensate the amount of uptake either. This study was performed to elucidate optimal fresh gas flow rates for rapid induction by comparison of changes of ratio of expired to inspired concentration. METHODS: The study population was composed of 107 patients undergoing thyroidectomy. Patients were randomly allocated to one of three groups who received desflurane or sevoflurane or isoflurane. Each group was randomly subdivided into three groups who received one of the fresh gas flow rate: 2, 5 or 10 L/min. Inspired anesthetic concentration (Fi) and expiratory anesthetic concentration (Fe), delivered concentration (FD) were recorded. RESULTS: With same fresh gas flow rates, there were significant differences between Fe/Fi of desflurane, sevoflurane, isoflurane. With same anesthetics, Fe/Fi of desflurane and sevoflurane were not influenced by fresh gas flow rates. But Fe/Fi of isoflurane at 2 L/min was significantly lower than 5 L/min and 10 L/min. Fi/FD of desflurane at 10 L/min did not differ from sevoflurane. At 2 L/min and 5 L/min, Fi/FD of desflurane was highest and then sevofluane, isoflurane in that order. CONCLUSIONS: Because rates of Fe/Fi of desflurane and sevoflurane were not influenced by fresh gas flow rates, 2 L/min of fresh gas flow rates could be selected. However, considering the wash-in time in circuit, optimal choice of fresh gas flow rate for desflurane and sevoflurane could be 5 L/min, that of isoflurane be 10 L/min.
