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.

Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
