Brief Summary

Erector spinae plane block (ESPB) as a new trunk fascia block technique was proposed in 2016. ESPB has aroused the interest of many nerve block experts. The benefits of ESPB are not yet demonstrated. The specific mechanism is still controversial. Some believe that ESPB can block the posterior root of the spinal nerve and produce part of the para-spinal block effect with the diffusion of the drug solution. The present study will carried out to compare the performance of the erector spinae plane block combined with general anesthesia in addicts versus non addicts' patients regarding the local analgesic effect, recovery after surgery and side effects.

Outcome Measures

Primary Outcomes (1)

  • The quality of recovery score (QoR-15) at 24th hour

    This questionnaire covers a total of 15 questions under five clinical dimensions of health; physical comfort (five-item), emotional status (four-item), psychological support (two-item), physical independence (two-item) and pain (two-item). a numerical rating scale of 11 point for each question leads to a minimum score of 0 (very poor recovery) and a maximum score of 150 (excellent recovery).

    at 24th hour

Secondary Outcomes (5)

  • Postoperative pain.

    At half an hour, 2, 4, 8, 12, 24 hours.

  • Intraoperative fentanyl dosage.

    From the start of operation till its end up to 3 hours.

  • First-time morphine use.

    In 24 hours

  • First time to ambulation after surgery.

    In 24 hours

  • Length of hospital stay.

    up to 3 days.

Interventions

Patients will be placed in left lateral position. A low-frequency curved array ultrasound transducer will be used. The ultrasound transducer will be placed in a longitudinal orientation 2-3 cm lateral to the midline to identify the hyperechoic line of the transverse process. After identification of muscles superficial to the transverse process and local infiltration of anesthesia into the superficial tissues, a block needle will be inserted in a craniocaudal direction until contact will be achieved with the transverse process where the tip will lay in the interfascial plane below the erector spinae muscle. A small bolus of local anaesthetic should be given through the block needle; the erector spinae muscle should be visualized, separating from the transverse process. A total of 20 mL bupivacaine 0.25% will be injected into the interfacial plane deep to the erector spinae muscle bilaterally. Forty minutes after the ESPB, the cutaneous sensory block will be assessed.
