Placenta accreta spectrum anaesthetic management with neuraxial technique can be facilitated by multidisciplinary groups.

Background: The concern about massive haemorrhage associated with placenta accreta spectrum (PAS) prompts the routine use of general anaesthesia (GA) at many centres. We aimed to describe the effects of establishing a fixed multidisciplinary team (PAS team) on anaesthetic practices and clinical results.

Methods: In this before-and-after study, we included patients with prenatal PAS suspicion treated between December 2011 and December 2019. We evaluated the anaesthetic techniques used before (Group 1) and after (Group 2) a PAS team was established.

Results: Eighty-one patients were included. Neuraxial anaesthesia (NA) was used in 23.3% of group 1 patients and 76.4% of group 2 patients. Likewise, the frequency of conversion to GA after initial management with NA decreased from 14.3% in group 1 to 7.7% in group 2.

Conclusions: The establishment of a PAS team is related to increased use of NA during the management of PAS patients.
