• Conditions: Block
• Interventions: Procedure: erector spinae plane block; Procedure: external oblique intercostal plane block

• Registration Number: NCT06097286
• Lead Sponsor: Ain Shams University

Brief Summary

Upper abdominal incisions, such as the oblique subcostal laparotomy, can cause severe pain and can lead to significant respiratory impairment.

Erector spinae plane (ESP) block is the deposition of local anaesthetic (LA) in the interfascial plane at the paraspinal region. It provides effective visceral and somatic analgesia.

External oblique intercostal plane (EOIP) block is a newly described block at which local anaesthetic (LA) is deposited in the interfascial plane deep to external oblique muscle at the sixth intercostal space. It provides blockade of the thoracoabdominal nerves at the level of T6 to T10.

In this study, the investigators compare between ultrasound (US) guided external oblique intercostal plane block and erector spinae plane block, in providing postoperative analgesia for upper abdominal surgeries

Primary Outcome Measures

Name	Time	Method
amount of total 24 hour pethidine consumption (mg) .	24 hours postoperatively	to measure total 24 hour pethidine consumption postoperatively.

Secondary Outcome Measures

Name	Time	Method
visual analogue scale (VAS) at rest and movement.	24 hours postoperatively	recorded postoperative immediately and 2, 4, 6, 8, 12, 18 and 24 hours. The Visual Analogue Scale (VAS) measures pain intensity. The visual analogue scale (VAS) consists of a 10 cm line, with two end points representing 0 (no pain) and 10 (pain as bad as it could possibly be).
mean arterial blood pressure (MAP)	24 hours postoperatively	recorded postoperative immediately and 2, 4, 6, 8, 12, 18 and 24 hours
heart rate (HR)	24 hours postoperatively	recorded postoperative immediately and 2, 4, 6, 8, 12, 18 and 24 hours
time to start mobilization	24 hours postoperatively	recorded postoperative immediately and 2, 4, 6, 8, 12, 18 and 24 hours
incidence of postoperative complications (nausea and vomiting)	24 hours postoperatively	recorded postoperative immediately and 2, 4, 6, 8, 12, 18 and 24 hours
