Anaesthesia

Mallampati class has been shown to increase during labour. Epidural analgesia might influence this change. The aim of our study was to compare the change in Mallampati class during labour in parturients who did and did not receive epidural analgesia and study the association of these changes with pre-defined clinical characteristics. ⋯ Of the relationships between change in Mallampati class and the other factors studied, only the total dose of epidural levobupivacaine during labour demonstrated a weak positive correlation 0.17 (p=0.039) with Mallampati class. This study confirms that labour is associated with an increase in the Mallampati class in approximately one third of parturients. Our findings indicate that having an epidural does not influence the likelihood of a change in Mallampati class during labour.
