Anesthesia Tutorial of the Week Quiz

1) First-generation SGAs do not have an integrated bite block.

2) Third-generation supraglottic airway devices combine second-generation SGA features with integrated video capabilities.

3) The Air-Q was the first SGA designed as a tracheal intubation conduit.

4) The gastric tube bubble test, suprasternal notch tap test, and gastric tube insertion are used to confirm the adequate positioning of all SGA generations.

5) The integrated gastric port in second-generation SGAs is used to pass an esophageal temperature probe.

6) Blind intubation through an SGA has a similar first-pass success rate to fiberoptic-guided intubation.

7) Only Nondepolarizing NMBAs can be used to improve the conditions for SGA placement.

8) Using NMBAs during the placement phase of SGAs blunts all protective airway reflexes except bronchospasm.

9) It is believed that using second-generation SGAs with gastric ports may lower the incidence of regurgitation and aspiration.

10) Any patient with suspected gastric contents should not be managed with an SGA unless required.

11) Macroglossia, vocal cord polyps, vocal cord paralysis, and high BMI are predictors of difficult SGA insertion or ventilation.

12) Both the DAS 2015 guidelines and ASA 2022 guidelines emphasize the use of SGAs in reestablishing alveolar oxygenation before declaring a “Can’t Intubate, Can’t Oxygenate” (CICO) scenario.

13) SGAs are contraindicated in procedures requiring patients to be in the prone position.

14) The Difficult Airway Society and the Obstetric Anaesthetists’ Association recommend using second-generation SGAs for airway maintenance and rescue ventilation following failed tracheal intubation in obstetric patients.

15) The 2015 DAS Guidelines recommend using SGAs as first-line airways to re-establish alveolar oxygenation after two failed attempts at tracheal intubation.

16) Mispositioned SGAs do not provide a patent and clinically acceptable airway.

17) Children with congenital conditions like Goldenhar Syndrome, Pierre Robin Sequence, Treacher Collins Syndrome, Klippel-Feil Syndrome, Crouzon Syndrome, and Down Syndrome can present with difficult airways.

18) Difficult TI occurs in 3.3% of obstetric patients and is unanticipated in two-thirds of these cases.

19) Direct SGA-guided flexible bronchoscopic intubation (direct SAGFBI) can be done with any sized ETT.

20) In obese patients, Trendelenburg position during SGA placement and pressure support ventilation can help optimize respiratory mechanics.
