Brief Summary

Open Gastrectomy surgery is a big surgery with upper umbilical median incision where the postoperative pain is occur frequently. pain managements of this surgery with intravenous opioid analgesics are currently standard approach. but its side effects as sedation, decreased bowel movement and respiratory depression are limiting its use. so local anesthesia done with regional block methods provides good analgesia after surgery that decrease use of opioid analgesics. in this study we intend to compare subcostal TAP block with external oblique intercostal block

Conditions

Postoperative Pain; Analgesia

Keywords

SCTAP; External Oblique Intercostal block; postoperative analgesia

Outcome Measures

Primary Outcomes (2)

• Need of morphine analgesia

  postoperatively monitoring of patients that need analgesics by morphine consumption using a patient contral analgesics device that record amount of used and wanted analgesics by patients themselves

  24 hours

• patients pain scales

  asking patients for pain at postoperative period by visual analog scale and score accordingly

  24 hours

Study Arms (2)

Subcostal Transversus Abdominis Plane (SCTAP) block.

ACTIVE COMPARATOR

SCTAP Block is performing by USG probe positioned on the anterior abdominal wall immediately inferior to the costal margin and then needle advanced to 2 to 3 cm lateral to the aponeurosis of the external oblique muscles, internal oblique muscles, and transversus abdominis in the TAP. Saline 0.5mL was injected to determine the position of the transverse fascia and 15-20 ml local anesthetics injected both in right and left sides of abdomen.

Procedure: subcostal TAP

External Oblique Intercostal (EOI) block

ACTIVE COMPARATOR

EOI block is performed by placing the US probe in paramedian sagittal orientation at the T6-7 level and visualizing the external oblique and intercostal muscles. Local anesthetics inject the under the external oblique muscle.

Procedure: EOIPB
