Brief Summary

Since its first description by Forero et al. there have been many articles and case reports including an increasingly number of indications for the ESP block: chronic and acute pain treatment, rib fractures management in the emergency setting, treatment of abdominal surgical pain, hip arthroplasty , analgesic management in breast surgery,or in spinal surgery.Although ESP block successfully reduced postoperative opioid consumption in clinical reports, no studies thus have investigated the optimum volume of bupivacaine for ESP block as regard a review of the medical literature on December 27th, 2017 that searched terms in 14 articles clearly stated the volume of the bolus and the spread of the anesthetic after an injection of LA, the volume needed to cover one dermatome widely varies from 2.5 mL to 6.6 mL, with a median value of 3.4 mL. Furthermore, the maximum number of dermatomes reached by a single bolus in ESP was of 9 dermatomes after a 30 mL bolus. Thus, in this study, the investigators evaluate the effect of ESP block which will be performed by using three different volumes (2.5, 3.4 ,6.6 ml/segment) of bupivacaine with the same concentration ,technique ,site of injection and operation.

Outcome Measures

Primary Outcomes (1)

  • postoperative morphine consumption in milligrams in the three groups

    if NRS is 4 or more a 5 mg morphine IV with maximum dose of 10 mg every 6 hours will be given and the total consumption of these medications will be recorded.

    24 hours

Study Arms (4)

E1

EXPERIMENTAL

will receive erector spinae block with 0.25% bupivacaine volume of 2.5 ml/segment

Procedure: erector spinae block by 0.25% bupivacaine

E2

EXPERIMENTAL

will receive erector spinae block 0.25% bupivacaine with volume of 3.4ml/segment

Procedure: erector spinae block by 0.25% bupivacaine

E3

EXPERIMENTAL

will erector spinae block receive 0.25% bupivacaine with volume of 6.6 ml/segment

Procedure: erector spinae block by 0.25% bupivacaine

C

NO INTERVENTION

will not receive erector spinae block

Interventions

A mark will be applied on the required level (T8), the midline (spinous processes) and the injection points 3 cm from midline.While the patient is in a sitting position with support from a member of staff, Preparation of the field with iodine will be made. Using ultrasound guidance with a 6-10 MHz linear probe anatomical landmarks will be identified including the transverse process at T8 level and the three layers of muscles from posterior to anterior: trapezius-rhomboid-erector spinae. After subcutaneous lidocaine 2% injection a 22-G spinal needle will be inserted under ultrasound guidance in plane, aiming towards the transverse process. After a Gentle contact with the transverse process, 0.25% bupivacaine is injected in increments with careful repetitive aspiration to avoid intravascular injection.

Also known as: erector spinae plane block
