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

Interventions

PROCEDUREexternal oblique intercostal plane block

o EOIP Group (ŋ=25): Patients will receive ultrasound guided External oblique intercostal plane block with 20 ml of LA mixture (10 mL of bupivacaine 0.5%, 5 mL of lidocaine 2% and 5 mL of normal saline to make a total volume of 20 ml.) at the end of procedure, unilaterally or bilaterally according to the surgery.

PROCEDUREerector spinae plane block

o ESP Group (ŋ=25): Patients will receive ultrasound guided Erector spinae plane block with 20 ml of LA mixture (10 mL of bupivacaine 0.5%, 5 mL of lidocaine 2% and 5 mL of normal saline to make a total volume of 20 ml.) at the end of procedure, unilaterally or bilaterally according to the surgery.

Design outcomes

Primary

MeasureTime frameDescription
amount of total 24 hour pethidine consumption (mg) .24 hours postoperativelyto measure total 24 hour pethidine consumption postoperatively.

Secondary

MeasureTime frameDescription
visual analogue scale (VAS) at rest and movement.24 hours postoperativelyrecorded 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 postoperativelyrecorded postoperative immediately and 2, 4, 6, 8, 12, 18 and 24 hours
heart rate (HR)24 hours postoperativelyrecorded postoperative immediately and 2, 4, 6, 8, 12, 18 and 24 hours
incidence of postoperative complications (nausea and vomiting)24 hours postoperativelyrecorded postoperative immediately and 2, 4, 6, 8, 12, 18 and 24 hours
time to start mobilization24 hours postoperativelyrecorded postoperative immediately and 2, 4, 6, 8, 12, 18 and 24 hours
