The Cp and Ce of propofol (PCp and PCe) and remifentanil (RCp and RCe) before anesthesia induction, at the end of surgery, and at the time of extubation were respectively recorded. Predictive performance was assessed using the jackknife method.Results: At the time of extubation, PCp was 1.17 ± 0.168 (95% CI: 1.14– 1.20 μg/mL), PCe was 1.7 ± 0.212 (95% CI: 1.65– 1.74 μg/mL), RCp was 0.769 ± 0.12 (95% CI: 0.75– 0.79μg/mL), and RCe was 0.972 ± 0.179 (95% CI: 0.94 − 1.01 μg/mL). The Pk values of PCp, PCe, RCp and RCe were 0.999, 0.993, 1.00 and 0.995, separately. Postoperative decreases in PCp (r = 0.089, p < 0.001), PCe (r = 0.087, p= 0.001), RCp (r = 0.072, p < 0.000) and RCe (r = 0.077, p < 0.001) were significantly correlated with the recovery time.Conclusion: PCp, PCe, RCp and RCe, together with OAA/S Scale and the recovery of spontaneous respiration might be potential reference indicators for extubation in day-surgery hysteroscopy following general anesthesia using TCI.Keywords: day surgery, effect-site concentration, plasma concentration, prediction probability, target-controlled infusion |
