Brief Summary:
The aim of this study is to compare the analgesic effect and safety profile of erector spinae plane block with transverses abdominis plane block in controlling peri-operative pain for lower abdominal cancer surgery.

Condition or disease Intervention/treatment Phase
Postoperative Pain Procedure: lower abdominal surgery Other: Erector spinae plane block Other: Transversus abdominis plane block Not Applicable

Detailed Description:

Pain triggers a complex biochemical and physiological stress response leading to impairment of pulmonary, immunological and metabolic functions. Opioids are the current gold standard drug for postoperative pain relief, however exposure to large doses lead to multiple side effects of varying significance such as nausea, vomiting, dizziness, constipation, respiratory depression, hypoventilation and sleep breathing disorders. Therefore strategies other than opioids are recommended without sacrificing proper and effective analgesia. Especially in cancer patients who are more susceptible to tolerance and addiction.

The Transversus Abdominis Plane (TAP) block, is a regional anaesthesia technique used effectively in laparotomies. Unilateral analgesia to the skin, muscles, and parietal peritoneum of the anterior abdominal wall will be achieved without affecting visceral pain, when the anterior rami of the lower six thoracic nerves (T7-T12) and the first lumbar nerve (L1) are blocked.

Erector spinae plane block (ESPB) was shown to be an effective analgesic option for different types of surgeries. It's relatively a simple block, drug is injected in the plane between the erector spinae muscle and the vertebral transverse process. Blocking the ventral and dorsal rami of spinal nerves on the paravertebral area distributed from T2-T4 to L1-L2 and gives good coverage to visceral pain. Owing to the lower risk of blood vessel damage and neural damage compared to the epidural or the paravertebral block.

Both blocks haven't been compared to each other in this type of surgery before.

Patients will undergo lower abdominal surgery under general anesthesia.

Other: Transversus abdominis plane block
patients will receive transversus abdominis plane block using 20 mL levobupivacaine (0.25%).

Experimental: Erector spinae plane block
Patients will receive Erector spinae plane block.

Primary Outcome Measures :
  1. Total morphine consumption [ Time Frame: 24 hours ]
    The total amount of morphine which was consumed post-operatively measured in milligrams

Secondary Outcome Measures :
  1. Intraoperative fentanyl consumption. [ Time Frame: intraoperative ]
    The total amount of fentanyl which was consumed during the surgery measured in milligrams

Other Outcome Measures:
  1. Postoperative nausea and vomiting [ Time Frame: 24 hours postoperative ]
    the number of patients who had nausea and vomiting

  2. Time for first rescue analgesia. [ Time Frame: 24 hours postoperative ]
    the time at which the patient will request an analgesic

  3. Heart rate [ Time Frame: 24 hours ]
    the number of heart beats in one minute

  4. Numerical rating scale for pain assessment. [ Time Frame: 24 hours ]
    This is a numerical rating scale for pain assessment which ranges from 0 to 10 with the least pain at scale 0 and the worst pain at scale 10

  5. mean arterial blood pressure [ Time Frame: 24 hours ]
    the mean arteiral blood pressure measurend in mmHg
