BACKGROUND: The nature of operation alters the volume of distribution at steady state (Vdss) of drug. The hepatic extraction ratio of midazolam (0.3~0.7) could be influenced by hepatic blood flow (HBF), and hepatic enzyme activity. The pharmacokinetics of intravenous midazolam were determined in patients undergoing lung surgery. METHODS: Midazolam, 0.2 mg/kg, was administered to five patients undergoing lung surgery at 30 minutes after induction of anesthesia. Anesthesia was maintained with O2-enflurane for one lung ventilation. Blood samples from artery were drawn at increasing intervals for 12 h. Plasma midazolam concentrations were measured by gas chromatography. Computer simulations of the times required for 20%, 50%, and 80% decreases in midazolam concentrations were performed. RESULTS: A three compartment model best described the concentration versus time data. The volume of the central compartment (Vc) and volume of distribution at steady state (Vdss) were 4.3 2.8 l and 59.9 20.1 l, respectively. The elimination half-life was 3.4 2.2 h. Simulations indicate that under all the situations, the concentrations would decrease more rapidly in our patients in spite of similar Vdss and elimination half-life of patients undergoing minor gynecological surgery. CONCLUSION: The elimination half-life was in the range of previously reported values. The shorter recovery time is apparently due to relatively faster redistrubution, and relatively greater capacity for redistribution.

PURPOSE: To present the clinical outcomes of small incision lenticule extraction (SMILE) including visual quality analysis in Korean patients with myopia METHODS: The medical records of 228 eyes of 116 patients who underwent SMILE in HanGil Eye Hospital LASIK Center from May 2014 to Feb 2015 and were followed-up for at least 3 months was analyzed retrospectively. The patients were followed up at 1 day, 1 week, 1 month, and 3 months after the operation. Refractive value, visual acuity, intraocular pressure, and visual quality were measured at each visit RESULTS: Preoperatively, uncorrected distant visual acuity was 0.01 ± 0.02 in log MAR, spherical equivalent was -5.03 ± 1.72 diopters, intraocular pressure was 15.85 ± 2.85 mm Hg, and the objective scattering index (OSI) value was 0.68 ± 0.49. The postoperative uncorrected distant visual acuity was 0.13 ± 0.10, 0.05 ± 0.08, 0.04 ± 0.09, and 0.02 ± 0.04 and OSI was 2.16 ± 1.89, 1.25 ± 0.64, 1.14 ± 0.69, and 0.81 ± 0.36 at 1 day, 1 week, 1 month, and 3 months after the operation, respectively. The postoperative intraocular pressure was 12.55 ± 3.74 mm Hg, 13.03 ± 4.35 mm Hg, 11.65 ± 2.49 mm Hg at 1 week, 1 month, and 3 months after the operation. The efficacy of refractive surgery 3 months after the operation was 0.97 ± 0.11, the safety was 0.99 ± 0.10, and predictability was 99.56% and 100.00% at the range of ±0.5 diopters and ± 1.0 diopter, respectively. CONCLUSIONS: The SMILE operation showed comparable clinical outcomes with conventional refractive surgery in terms of efficacy, safety, and predictability. Intraocular pressure and visual quality normalized gradually throughout the 3-month postoperative period.

BACKGROUND: The present study was performed to elicit what effect nalbuphine would have on isoflurane MAC (minimum alveolar concentration) in the patients undergoing lower abdominal surgery. METHODS: Sixty-two women were randomly allocated to one of five study groups to receive an intravenous injection of no nalbuphine (group I), 0.25 mg/kg (group II), 0.5 mg/kg (group III), 1.0 mg/kg (group IV), 1.5 mg/kg (group V). Anesthesia and tracheal intubation were induced with propofol 2 mg/kg, succinylcholine 1 mg/kg. Patients were inhaled at a preset end-tidal concentration of isoflurane, which was maintained for 20 min. Response to skin incision, movement or no movement, was determined 30 minutes after nalbuphine injection. The isoflurane concentration of the next patient in the same group moved up or down in steps of 0.1~0.3%, according to the previous patient's response. MAC was determined using the "up-down" method and logistic regression. RESULTS: The MAC's of isoflurane were 1.09 vol% end-tidal in the control group, 0.89 vol% in group II, 0.65 vol% in group III, 0.55 vol% in group IV, and 0.51 vol% in group V. CONCLUSIONS: It would be suggested that nalbuphine dose-dependently reduce the isoflurane MAC, and have ceiling effect on the reduction of isoflurane MAC.
