Background:-A popular method of providing anaesthesia for insertion of SGA device is with the use of bolus intravenous propofol, however it is associated with adverse effects like hypotension, apnoea, and pain on injection. Sevoflurane is a halogenated volatile anaesthetic which satisfies the conditions required for SGA devices insertion without the side effects as seen with propofol. Objective: - To compare conditions for SGA insertion following anaesthesia with inhalation of sevoflurane or intravenous injection with propofol. Methods: - 128 Patients posted for routine surgeries under general anaesthesia taken as study subject and randomly divided into 2 groups of 64 each. After premedication, Group P received intravenous propofol (2mg/kg body weight) with 100% oxygen via the face mask. In group S, Magills circuit primed with Sevoflurane 8% in N2O 50% and O2 50 % (flow rate –8lit/min) for 30 seconds connected to the face mask. After Loss of eyelash reflex, SGA insertion was attempted. The time taken from induction of anaesthesia to loss of eyelash reflex, time taken from loss of eyelash reflex to successful SGA insertion and hemodynamic parameters at baseline, at induction and every min for 5 minutes after induction were recorded in both the groups. Data was analysed using student’s t-pair test and statistical significance set at P<0.05. Results Successful LMA insertion in first attempt was 100% in group P with excellent conditions while in group S it was 89.067% (57 patients) with excellent to satisfactory conditions. Mean arterial pressure was observed statistically significant between the groups (p=0.03) Conclusion: - Sevoflurane requires greater time for LMA insertion but with better haemodynamic stability. So, it can be used as an alternative.

Context:  Patient ventilation volume and rate have been found to be compromised due to the inability to seal a pocket mask over the chinstrap of football helmets. The effects of supraglottic airway devices such as the King LT and of lacrosse helmets on these measures have not been studied. Objective:  To assess the effects of different airway management devices and helmet conditions on producing quality ventilations while performing cardiopulmonary resuscitation on simulation manikins. Design:  Crossover study. Setting:  Simulation laboratory. Patients or Other Participants:  Thirty-six athletic trainers (12 men, 24 women) completed this study. Intervention(s):  Airway-management device (pocket mask, oral pharyngeal airway, King LT airway [KA]) and helmet condition (no helmet, Cascade helmet, Schutt helmet, Warrior helmet) served as the independent variables. Participant pairs performed 2 minutes of 2-rescuer cardiopulmonary resuscitation under 12 trial conditions. Main Outcome Measure(s):  Ventilation volume (mL), ventilation rate (ventilations/min), rating of perceived difficulty (RPD), and percentage of quality ventilations were the dependent variables. Results:  A significant interaction was found between type of airway-management device and helmet condition on ventilation volume and rate (F12,408 = 2.902, P &lt; .0001). In addition, a significant interaction was noted between airway-management device and helmet condition on RPD scores (F6,204 = 3.366, P = .003). The no-helmet condition produced a higher percentage of quality ventilations compared with the helmet conditions (P ≤ .003). Also, the percentage of quality ventilations differed, and the KA outperformed each of the other devices (P ≤ .029). Conclusions:  The helmet chinstrap inhibited quality ventilation (rate and volume) in airway procedures that required the mask to be sealed on the face. However, the KA allowed quality ventilation in patients wearing a helmet with the chinstrap fastened. If a KA is not available, the helmet may need to be removed to provide quality ventilations.

We compared proseal, supreme, and i-gel supraglottic airway devices in terms of oropharyngeal leak pressures and airway morbidities in gynecological laparoscopic surgeries. One hundred and five patients undergoing elective surgery were subjected to general anesthesia after which they were randomly distributed into three groups. Although the oropharyngeal leak pressure was lower in the i-gel group initially (mean ± standard deviation; 23.9 ± 2.4, 24.9 ± 2.9, and 20.9 ± 3.5, resp.), it was higher than the proseal group and supreme group at 30 min of surgery after the trendelenburg position (25.0 ± 2.3, 25.0 ± 1.9, and 28.3 ± 2.3, resp.) and at the 60 min of surgery (24.2 ± 2.1, 24.8 ± 2.2, and 29.5 ± 1.1, resp.). The time to apply the supraglottic airway devices was shorter in the i-gel group (12.2 (1.2), 12.9 (1.0), and 6.7 (1.2), resp.,P=0.001). There was no difference between the groups in terms of their fiber optic imaging levels. pH was measured at the anterior and posterior surfaces of the pharyngeal region after the supraglottic airway devices were removed; the lowest pH values were 5 in all groups. We concluded that initial oropharyngeal leak pressures obtained by i-gel were lower than proseal and supreme, but increased oropharyngeal leak pressures over time, ease of placement, and lower airway morbidity are favorable for i-gel.
