Epidural analgesia is the recommended analgesic technique in patients having surgery with severe postoperative pain such as thoracic and upper abdominal surgery. However, from the previous study, the incidence of inadequate pain control in patients receiving epidural analgesia is very high 48.6% in our hospital.
A high incidence of inadequate epidural analgesia may result from variety of epidural techniques and epidural drug administrations. The protocol based practice has been developed from acute pain service which founded for more than 10 years. By using protocol based practice, the investigators believed that the incidence of inadequate epidural analgesia will be less compared with the current practice.

Epidural insertion and epidural drug administration depend on anesthetist in charge
Epidural insertion and epidural drug administration depend on anesthetist in research team using protocol based 1. insertion at mid-level of surgical insertion 2. insertion depth is 3-5 cm in space, not more than 5 cm 3. using benzoin tincture and transparent dressing to fix catheter 4. test dose with 2%xylocaine with adrenaline 1:200,000 3ml If not cover desired dermatome: 2% lidocaine with adr added 3 ml every 5 min (up to 2 times) 5. After induction and patients' hemodynamic are stable. Load 2 mg morphine with 0.0625% bupivacaine + morphine 0.02 mg/ml 3 ml then continuous infusion with rate according to initial local anesthetic requirement for incisional area coverage

Overall incidence of inadequate epidural analgesia
To compare the overall incidence of inadequate epidural analgesia until considered removal between protocol-based and current practice by using the definition of inadequate analgesia as pain score of 4 or more out of 10 on numeric rating scale (0; no pain, 10; worst imaginable pain) at rest.
Time frame: 72 hours
Side effects
To compare the incidence of undesirable side effects of epidural catheter between groups: sedation, respiratory depression, hypotension, motor weakness, postoperative nausea and vomiting and pruritus
Time frame: 72 hours
