hmm... i think if i were you, i'd call up the surgical dept and query this - my PCAS was via an epidural, as described here in Wiki....
Patient-controlled epidural analgesia (PCEA) is a related term describing the patient-controlled administration of analgesic medicine in the epidural space, by way of intermittent boluses or infusion pumps. This can be used by women in labour, terminally ill cancer patients or to manage post-operative pain.
so, the fact that they've worded it 'epidural' might actually mean you'll get the general anesthesia for the operation through that site, and the PCAS as well, for post surgery pain.
