| Preoperative management | |
| Patient educated about the pathway in the surgical clinic | |
| Preoperative bowel preparation is not routinely used | |
| Patients allowed clear fluids until 2 h before the start of surgery | |
| 500 mL carbohydrate drink 2 h before surgery (Clearfast) | |
| Oral adjunctive analgesics given preoperatively: acetaminophen, gabapentin | |
| Alvimopan given preoperatively | |
| Transdermal scopolamine patch applied in preoperative holding unless contraindicated | |
| Low thoracic epidural placed with small amount of IV fentanyl and/or midazolam for sedation | |
| Heparin 5000u SC given after epidural placement and before incision | |
| Antibiotic prophylaxis: cefazolin or clindamycin if penicillin allergic | |
| Intraoperative management | |
| Induction: lidocaine, propofol, fentanyl up to 150 μg, neuromuscular blocking drug of choice | |
| Goal is to avoid IV opioids, no IV opioids after induction without discussion with attending anesthesiologist | |
| Dexamethasone 4 mg IV after induction | |
| ASA standard monitors and arterial line with cardiac output monitor | |
| Volatile anesthetic titrated to keep BIS 40–60 | |
| Option for epidural hydromorphone 0.4 mg at induction | |
| Epidural infusion bupivacaine 0.0625–0.25% ± hydromorphone 10 μg/mL run at 3–6 mL/h | |
| Ketamine infusion 4 μg/kg/min may be used in chronic pain patients | |
| Ondansetron 4 mg IV given at the end of surgery | |
| Acetaminophen 1 g IV and ketorolac 15 mg IV given towards end of the case if appropriate | |
| Fluid management: | |
| Maintenance crystalloid infusion (LR) 3 mL/kg based on ideal body weight | |
| Goal-directed fluid therapy—colloid boluses to maximize stroke volume | |
| Record initial stroke volume (SV) | |
| After incision, give 250 mL colloid bolus over < 15 min | |
| If SV increases by > 10%, repeat bolus | |
| If SV increases by < 10%, patient does not require a further bolus | |
| Record peak value achieved | |
| If still hypotensive, consider phenylephrine bolus or infusion | |
| Give a further colloid bolus when SV drops 10% from peak value | |
| Repeat cycle | |
| Blood products transfused as needed | |
| Postoperative management | |
| Epidural bupivacaine 0.0625–0.125% ± hydromorphone 10 μg/mL run at 4–6 mL/h for up to 72 h | |
| (Hydromorphone 10 μg/mL alone may be used in hypotension is a problem) | |
| Scheduled adjunctive analgesia with acetaminophen and NSAIDs whenever possible | |
| Patients transitioned to oral opioids after removal of epidural catheter | |
| Patients encouraged to drink liquids immediately after surgery | |
| Alvimopan given postoperatively for 5 days or until first stool | |
| IV fluids discontinued once adequate oral intake is achieved, usually the first morning after surgery | |
| All preoperative medications are restarted when patients tolerate oral intake | |
| Patients cared for in an environment that encourages early mobilization | |
| Encouraged to be out of bed on the day after surgery and for at least 6 h on every subsequent day | |
| Patients are asked to maintain a diary of their activity and sleep |
