What kind of iv access (regular, picc, midline?) is typically used for abdominal anterior resection surgery?

IV access: If you are relatively healthy and do not require central line, the most is needed peripheral IV access. Your anesthesiologist knows the surgeon, his skills and potential for blood loss, ( which is unlikely). Anesthesiologist will make decision what kind of access he/she needs. When the patient is asleep he can start second IV if nessasary.

Large Bore IV: Requirements vary based upon patient age, general physical condition, reasons for the surgery, and coexisting medical problems. In an otherwise healthy individual, one (or two) large bore (18-16g) ivs should be sufficient to maintain blood and organ perfusion pressures. Many surgeons prefer central line placements pre or intra-operatively, anticipating blood loss or need for antibiotics postop.
