“…Other studies have used loss of response to verbal commands, dropping of weighted objects and relaxation of jaw muscles for jaw thrust as end points of induction. 7,13 There was statistically significant faster induction time with propofol than vital capacity breath induction with sevoflurane in our study. This was concurring with the results of Hall et al, Thwaith et al, Ti et al but was found to be not clinically significant.…”

Background: The increasing emphasis on day care anaesthesia has led to the greater use of laryngeal mask airway (LMA) as an alternative to tracheal intubation for short procedure surgeries. Satisfactory insertion of LMA after induction of anaesthesia requires sufficient depth for suppression of airway reflexes. This study was performed to compare intravenous induction with Propofol to vital capacity breath induction with sevoflurane for LMA insertion. Methods: In this study 100 ASA 1 and ASA 2 patients aged between 20 and 40 years, undergoing short surgical procedures lasting 30 to 60 minutes, were included. The P group received Inj. Propofol 2.5 mg/kg IV whereas the S group received Sevoflurane 8% vital capacity breaths. After the loss of eyelash reflex, which was considered the end point of induction, the LMA insertion was attempted by an anaesthesiologist blinded to the induction technique. The data that was recorded was induction time with both the drugs, characteristics of LMA insertion, hemodynamic responses and complications if any. The number of attempts at insertion was also noted.Results: Induction time was 60.1±8.98 secs for propofol induction and 72.8±15.86 for sevoflurane vital capacity breath induction which was found statistically significant. The insertion conditions were found excellent in 88% in the propofol group and 90% in the sevoflurane group which was comparable. There was no statistically significant difference found in the time or characteristics of insertion between both the groups. No incidence of complications was found in both groups. Conclusions: Induction with sevoflurane vital capacity breath inhalation compared equally with induction with intravenous propofol for LMA insertion in patients undergoing short surgical procedures.

“…Subanaesthetic concentrations offer advantages to mothers including a lack of irritation to the respiratory tract and a pleasant odour. [1][2][3][4] In addition, sevoflurane has a low blood-gas partition coefficient of 0.65 that enables rapid uptake into the central nervous system together with fast washout which results in swift clinical effect and recovery. 2 The only agents with lower blood-gas partition coefficients are desflurane and nitrous oxide with values of 0.45 and 0.47, respectively.…”

“…16 In this study, the time to loss of eyelash reflex during IIAS without premedication, approximately 60 sec, is consistent with previous publications 5,6,[15][16][17][18][19] showing times ranging from 35 to 90 sec. 2,4,7,20,21 These differences can be explained by the different ways IIAS can be performed. Basically, anesthesiologists may ask their patients to breathe normally or they may choose to rely on the singlebreath inhalation technique.…”

“…Basically, anesthesiologists may ask their patients to breathe normally or they may choose to rely on the singlebreath inhalation technique. 4,6 Although the latter is praised by some, 22 its real efficacy is controversial 20,21 and requires patient cooperation, which may be altered by premedication. For these reasons, we opted for the normal breathing approach.…”

Purpose We investigated the effects of a combination of low-dose fentanyl-midazolam premedication on the speed of inhaled induction with sevoflurane and ProSeal TM laryngeal mask airway (PLMA) insertion conditions. Methods Eighty adult patients undergoing elective surgery were randomized in a double-blind fashion to receive either a normal saline placebo (Group PLAC) or a fentanyl 0.6 lg Á kg -1 and midazolam 9 lg Á kg -1 premedication (Group FM) 5 min before tidal volume sevoflurane 8%/O 2 induction. Anxiety levels, times to loss of eyelash reflex (LER) and PLMA insertion, and cardiorespiratory data were recorded. Results Times to LER (Group PLAC: 66 ± 34 sec vs Group FM: 47 ± 18 sec, P = 0.0027, difference = 19 sec: 95% confidence interval [CI] 7-31 sec) and to PLMA insertion (Group PLAC: 186 ± 80 sec vs Group FM: 119 ± 44 sec, P \ 0.0001, difference = 68 sec: 95% CI 39-97 sec) were shorter following FM. After PLMA insertion, end-tidal sevoflurane concentration (EtSevo) was lower and end-tidal CO 2 (EtCO 2 ) was higher following FM. Respiratory rate (RR) was lower with FM, but there was no difference regarding tidal volume. Adverse events, such as movements and apnea, occurred more often in Group PLAC. Systolic blood pressure (SBP) and heart rate (HR) during induction were both lower with FM. Anxiety level after premedication was lower following FM administration. All participants remembered the face mask being applied in Group PLAC vs 69% in Group FM, P \ 0.0001. Conclusion Administration of a low-dose fentanylmidazolam combination prior to sevoflurane induction decreases time to LER and allows for more rapid and less eventful PLMA insertion. Both SBP and HR were lower when premedication was administered. Patients receiving premedication were less anxious and less likely to remember the face mask. However, premedication was associated with a lower RR and increased EtCO 2 values following PLMA insertion, in spite of lower EtSevo concentrations. (ClinicalTrials.gov ID NCT00723164).
