Background

•Higher incidences of failed intubation and challenging laryngoscopy in obstetric population1
•
•Videolaryngoscopy improves 1st pass in all patients2
•
•Difficult airway society and Obstetric Association of Anaesthetists recommend that videolaryngoscopes be readily available in all obstetric Gas
•
•NHS Lothian has McGrath MAC VL (MMVL) in all airway trolleys
 
Methods
 
•Data collected on all Obstetric GAs  from January 2023 to September 2024
•
•Intubation data was recorded by anaesthetists involved in the case
•
•Local Clinical Governance team and Caldicott approval was granted
 
 
Results
 
•Total of 548 Obstetric GA cases during study period
•
•Intubation data available for 473/548 (86.3%) cases
•
•MMVL used in 440/473 cases
•
•All failed intubations had uneventful surgeries using an iGel
 
Discussion
 
•Rates of challenging intubation are between 1.6-16.3% in obstetric populations1
•
•Our centre continues to have favourable data with 4/473 (0.8%) difficult intubations over the audit timeframe
•
•Continued use of best practice with MMVL use as first line has helped to maintain a high rate of successful first pass intubation
