Brief Summary

Pain after laparoscopic cholecystectomy (LC) is a common complaint that prolongs hospital stay and thus increases morbidity. There are three primary sources of pain after LC, incision site, local and systemic effects of pneumoperitoneum, and post cholecystectomy wound to the liver. External oblique intercostal plane block (EOIPB) has recently been described as a novel block for upper abdomen surgery. the probable mechanism of the block with the dyeing of both the anterior and lateral branches of the intercostal nerves T7-T10. This block also provides a dermatomal sensory block at the T6-T10 level in the anterior axillary region and the T6-T9 level in the midline.

Outcome Measures

Primary Outcomes (1)

  • total morphine consumption

    the total analgesic (morphine) requirements in the first 24 hours postoperatively will be calculated

    the first 24 hours postoperatively

Secondary Outcomes (1)

  • NRS

    6 hours postoperatively

Study Arms (2)

The EOIPB ( E) group

EXPERIMENTAL

EOIPB will be administered by a single anesthetists following the intubation. A linear ultrasound transducer is positioned in the sagittal plane at the 6th rib level, between the anterior axillary and midclavicular lines. The ribs, lungs, pleura, intercostal muscles, external oblique muscle and subcutaneous tissue are visualized in the image. The in-plane technique with a 22G, 80 mm block needle is used to inject 30 ml of 0.25% bupivacaine into the external oblique intercostal plane on both sides.

Drug: local anesthetic injection (bupivacaine)

The Control Group (C)

PLACEBO COMPARATOR

Control group of patients will receive standard multimodal analgesia. Using us guidance, the external oblique intercostal plane is identified and 30 ml normal saline instead of LA will be injected in the control group.

Other: normal saline injection

Interventions

The in-plane technique with a 22G, 80 mm block needle is used to inject 30 ml of 0.25% bupivacaine into the external oblique intercostal plane on both sides.

Also known as: bupivacaine
The EOIPB ( E) group

the control group will receive 30ml of normal saline bilaterally into the external oblique intercostal plane on both sides

Also known as: Placebo
The Control Group (C)
