Outcome Measures

Primary Outcomes (1)

  • Postoperative morphine consumption in the first 24 hours

    Morphine consumption in the first 24 hours were measured. Patients will be able to request opioids via a PCA device when their VAS score is above 3 at rest and during activity (coughing and deep breathing).

    Postoperative day 1

Secondary Outcomes (6)

  • Postoperative pain scores

    Postoperative month 3

  • The number of patient requiring rescue analgesia

    Postoperative day 1

  • Number of patients with postoperative nausea-vomiting and need of antiemetic usage

    Postoperative day 1

  • Remifentanil consumption during the surgery

    The remifentanil consumption will be recorded from anesthesia induction until the patient is referred to the recovery unit, up to 160 min]

  • Postoperative first oral intake time, first urination, first defecation time, first mobilization time, hospitalization time

    Postoperative 7 days on an average

  • +1 more secondary outcomes

Study Arms (2)

Group ESP

ACTIVE COMPARATOR

bilateral ESPB (total of 40 ml, %0.25 bupivacaine) + IV morphine PCA

Procedure: Erector spina plane block + general anesthesia

Group GA

ACTIVE COMPARATOR

only IV morphine PCA

Procedure: Only general anesthesia

Interventions

Bilateral-injection ultrasound-guided bilateral erector spinae plane block Pre-operatively, with the patient in the sitting position, 20ml 0.25% bupivacaine will be administered between the T9 spinous process and the erector spinae muscles with the guidance of an ultrasound probe placed on a parasagittal plane. The same procedure was applied bilaterally. Intraoperative analgesia: After anesthesia induction tenoxicam 20 mg IV and 30 min. before the end of the surgery paracetamol (1gr) iv was applied. Postoperative analgesia: IV-PCA: The requested dose will be 20µg/kg morphine, the lock-in time will be 6-10 minutes, the 4-hour limit will be 80% of the total calculated dose. Rescue analgesia was provided with iv tramadol 30 mg boluses whenever the Visual analog scale pain score \>3, (max doses 300 mg/day).

Masking Details
The patients were randomly divided into two groups of 30 patients each. In the system where computer generated random numbers (SPSS v23.0, IBM, NewYork, USA) were used, ESP and GA groups were determined at a ratio of 1:1. Sealed and sequentially numbered envelopes were created. One hour before the operation, an experienced anesthesiologist, who was not involved in the intraoperative and postoperative follow-up of the patient and would only perform the block procedure, opened a sealed opaque sealed envelope to learn the group that the patient would be included in. There were two different physicians who performed intraoperative and postoperative follow-up. Both of the follow-up physicians were blind to the patient group. The care provider and investigator were also blinded to the participant.
