“…Existing data suggest that vital capacity induction with sevoflurane results in a shorter time to loss of consciousness than propofol (25 sec vs 44 sec, respectively) but results in a longer time to successful insertion of a laryngeal mask airway device (1.3 min vs 2.2 min, respectively), findings since confirmed in other studies. [44][45][46][47] When sevoflurane and isoflurane were compared in singlebreath induction (5% vaporizer setting), the results showed equivalent time to loss of eyelid reflex (75 sec and 67 sec, respectively). 48 The effect of dose on time to onset has been documented.…”

“…In the present study, although most patients required additional breaths, induction times in our elderly patients were similar to those reported previously in young volunteers and patients. [1][2][3][4][5][6][7][8] Severe respiratory adverse events were not observed with high concentration sevoflurane induction. Although there were a few patients with a cough or hiccup associated with sevoflurane, our findings are similar to previous reports focusing on young volunteers and patients.…”

“…Although there were a few patients with a cough or hiccup associated with sevoflurane, our findings are similar to previous reports focusing on young volunteers and patients. [1][2][3][4][5][6][7][8] Furthermore, breath holding and a decrease in SpO 2 below 96% occurred in two patients who received an iv induction, but not in patients who received high concentration sevoflurane induction.…”

“…[1][2][3][4][5][6][7][8] Several studies in young volunteers and patients have demonstrated that HR increased slightly or not and that arterial blood pressure decreased 10 to 20% after inhalation induction with high concentrations of sevoflurane. [1][2][3][4][5][6][7][8] However, elderly patients are more sensitive to cardiovascular depression with volatile agents. 10,12,13 Cardiovascular instability may contribute to perioperative myocardial ischemia and cardiac morbidity in these patients.…”

“…[1][2][3][4][5] Compared to the conventional inhalation induction technique using a gradual increase of concentration, a high concentration sevoflurane induction produced a rapid induction and reduced adverse effects. 4 Furthermore, sevoflurane induction provided additional advantages such as good cardiovascular stability, 3,6,7 smooth transition between induction and maintenance, 6,8 and rapid onset of non-depolarizing muscle relaxant 9 compared with iv induction.…”

P Pu ur rp po os se e: : To establish the appropriate inhalation induction technique using a high concentration of sevoflurane in the elderly.M Me et th ho od ds s: : Forty-five patients, aged 70-79-yr-old, were randomly divided into three groups: 1) Group I: anesthesia was induced with propofol 2 mg·kg -1 and sevoflurane 2% (n = 15); 2) Group II: anesthesia was induced with a three-minute inhalation of sevoflurane 8%; 3) Group III: anesthesia was induced with inhalation of sevoflurane using a gradual reduction technique (8, 6, 4% for each minute). In Groups II and III, a modified vital capacity inhalation induction was performed. Mean arterial pressure (MAP), heart rate (HR) and oxygen saturation (SpO 2 ) were measured continuously during induction. In addition, induction time and adverse events related to anesthetic induction were recorded. R Re es su ul lt ts s: : The induction time in Group I was significantly shorter than that in Groups II and III (P < 0.05). However, there was no difference in the induction time between Groups II and III. In Groups II and III, the majority of patients required additional breaths. In comparison with the other groups, stability of MAP was maintained in Group III. The variations of HR in all groups were small. During induction, no patient experienced a decrease in SpO 2 below 96%, except for two patients in Group I. Severe respiratory adverse events were not observed. Other adverse events were similar in all groups.C Co on nc cl lu us si io on ns s: : Our results suggest that a high concentration sevoflurane induction using a gradual reduction technique may be an acceptable alternative to standard iv induction in elderly patients. II et III (P < 0,05 Objectif : Réaliser la technique appropriée d'induction par inhalation en utilisant une forte concentration de sévoflurane chez des patients âgés. Méthode : Quarante-cinq patients de 70-79 ans, ont été répartis de façon aléatoire en trois groupes : 1) groupe I : anesthésie induite avec 2 mg·kg -1 de propofol et du sévoflurane à 2 % (n = 15) ; 2) groupe II : anesthésie induite avec l'inhalation de sévoflurane à 8 % pendant 3 min ; 3) groupe III : anesthésie induite avec l'inhalation de sévoflurane selon la technique de réduction graduelle de la concentration (8, 6, 4 % pour chaque minute). Dans les groupes II et III, une induction par inhalation, avec modification de la capacité vitale, a été réalisée. La tension artérielle moyenne (TAM), la fréquence cardiaque (FR) et la saturation du sang en oxygène (SpO 2 ) ont été mesurées en continu pendant l'induction. De plus, le temps nécessaire à l'induction et les événements indésirables reliés à l'induction anesthésique ont été notés. Résultats : Le temps d'induction a été significativement plus court dans le groupe I que dans les groupes
