    (2009) Ozturk T.; Erbuyun K.; Keles G.T.; Ozer M.; Yuksel H.; Tok D.
    Background and objective The aim of this study was to compare the effects of sevoflurane vs. sevoflurane and remifentanil on cough and agitation during emergence and recovery after fiberoptic bronchoscopy. Methods Children between 2 and 6 years of age undergoing fiberoptic bronchoscopy were enrolled. All patients were premedicated with oral midazolam. Patients were randomly assigned to either group S (sevoflurane alone, n = 25) or group SR (sevoflurane with remifetanil, n = 25). Anaesthesia was induced and maintained with sevoflurane in all patients. Group SR received remifentanil at a bolus dose of 1 μg/kg over 2 min followed by a maintenance infusion of 0.15 μg/kg/min. In addition to routine anaesthesia documentation, agitation scores and cough scores were recorded every 5 min during emergence and recovery. Results Duration of the procedure, anaesthesia and emergence phases was similar in both groups (P>0.05). Time until recovery was significantly shorter in group SR than in group S (7.0 ± 5.5 min and 13.0 ± 3.5 min, respectively; P = 0.001). Cough scores were not significantly different between the two groups during emergence and recovery (Kruskal-Wallis ANOVA test, P0.05). However, the mean agitation score at 5 min in group SR was significantly higher than that in group S (Kruskal-Wallis ANOVA test, P<0.01). One case of hypoxaemia from thoracic rigidity occurred in a patient in group SR. Conclusion The addition of remifentanil significantly shortened recovery time in children undergoing fiberoptic bronchoscopy under sevoflurane anaesthesia. In the recovery period, remifentanil did not decrease cough, and increased agitation. © 2009 European Society of Anaesthesiology.

    Balanced anesthesia with dexmedetomidine added desflurane or sevoflurane in spinal surgery
    (2012) Keles G.T.; Ozer M.; Dede G.; Temiz C.; Horasan G.D.; Civi M.
    Objectives: Sevoflurane and desflurane inhalational anesthetics are used for fast-track neuroanesthesia. Dexmedetomidine is used to provide analgesia, sedation and hemodynamic stability. Other anesthetic and analgesic requirements decrease when dexmedetomidine is administered, thus it is an interesting option for intraoperative agent for general anesthesia. We aim to compare desflurane and sevoflurane with dexmedetomidine in the operating room (OR) and Post-Anesthesia Care Unit (PACU) by using Fast-Tract -Criteria (FTC) and Aldrete Criteria (AC) for spinal surgery patients. Methods: A double-blind study was conducted. One hundred ASA I-II patients aged 18-65 were randomly divided into two groups. Following the standard anesthesia induction, Group (D+D) (n=50) received 2-4 % desflurane + 0.2 μg/kg/h dexmedetomidine and Group (S+D) (n=50) received 1-3 % sevoflurane + 0.2 μg/kg/h dexmedetomidine in 60 % N2O for anesthesia management. Extubation times, and FTC and AC were evaluated in the OR at the 5th and 10th minutes and in PACU at the 5th, 15th and 25th minutes. P< 0.05 was considered significant. Results: Demographic features of the patients in the two groups were similar. Extubation time in Group (D+D) was shorter than that in Group (S+D) (5.9 ± 2.4 and 8.3 ± 3.9 min respectively, p=0.001). In OR at the 10th min, and in PACU at the 5th min; Group (D+D) had a higher AC score than did Group (S+D) (p=0.001), and also at the 15th min., Group (D+D) had a higher FTC (P=0.01) and AC (p=0.007) scores than did Group (S+D). In all the patients, targeted discharge points were achieved at the 25th minute in PACU Conclusions: Balanced anesthesia with desflurane / dexmedetomidine combination is superior to sevoflurane / dexmedetomidine in extubation time and time to reach an AC ≥ 9 and FTC ≥ 13 in spinal surgery. © 2012 Keles GT, et al.
