The effectiveness and adverse effects of continuous epidural analgesia was studied in I 04
patients undergoing thoracic operations at Siriraj Hospital. Patients were divided into 3 groups
according to the type of surgical approach and the technique of epidural analgesia. Group I
patients (n
=
72) received thoracic epidural block using bupivacaine and morphine combined
with light general anesthesia for exploratory thoracotomy; group 2 patients (n
=
21) received the
identical anesthetic technique, the operation was achieved through median sternotomy; group 3
patients (n
=
11) had a similar type of operation to group 1, the anesthetic technique was lumbar
epidural block using morphine and combined with light general anesthesia. Continuous epidural
morphine infusion was given 0.1-0.4 mg/h during postoperation in all patients for providing
adequate pain relief.
The results revealed that a I 0 em visual analogue scale (VAS) pain scores were satisfac-
tory and comparable in all groups. Lumbar epidural patients consumed a significantly larger dose
of morphine than thoracic epidural groups (P
