Summary

Effective pain management after abdominal surgery is essential for recovery. This study compares two pain relief methods-intrathecal morphine (a single spinal injection) and continuous epidural analgesia-for patients undergoing open colorectal cancer surgery.

The investigators expect intrathecal morphine to provide equal pain relief at rest 24 hours after surgery, while epidural analgesia may be more effective during movement. By 48 to 72 hours, both methods should offer similar pain control. The epidural group may require fewer additional pain medications but could experience more side effects, including a higher risk of low blood pressure and technical difficulties. Additionally, these patients may have a slightly longer hospital stay. In contrast, the intrathecal morphine group may have fewer overall side effects. Despite these differences, patient satisfaction, sleep quality, and recovery are expected to be similar in both groups.

By evaluating these methods, this study aims to determine the most effective and safe approach to post-surgical pain management, improving comfort and recovery outcomes for patients.

Conditions

  • Colorectal Carcinoma
  • Analgesia, Postoperative
  • Laparotomy

Interventions

DRUG

Intrathecal Morphine

In Spinal group, 25 G or 27 G pencil point needle, depending on the preference of the anesthesiologist, will be inserted at L2-L3 or L3-L4 intervertebral space and 300 μg of preservative-free morphine (Morphine Kalceks ®, Kalceks, AS, Riga, Latvija, 10mg/ml) diluted with sterile saline to a volume of 3 mL will be injected intrathecally.

PROCEDURE

Epidural Analgesia

Epidural analgesia with levobupivacaine and fentanyl mixture. For intraoperative intermittent analgesia, Epidural group will be given a loading dose of 5-10 milliliters of a mixture of 10 micrograms per milliliter (μg/mL) of fentanyl (Fentanyl Piramal Critical Care, 50 mcg/ml) and 0.25% levobupivacaine (Levobupivakain Kabi 5 mg/ml), followed by intermittent 4-5 mL boluses as needed throughout the surgery. Postoperative continuous epidural analgesia in the epidural group will consist of 2 μg/mL fentanyl added to 0.1 % levobupivacaine at the rate 5-8 mL/h during the first 24 hours after surgery.
