Brief Summary

The erector spinae plane block (ESPB) is a new technique that is increasingly used in the treatment of acute and chronic pain. Bariatric surgery is a surgical treatment method used in the treatment of morbid obesity and related comorbidities. Providing pain control in obese patients is a topic that remains up-to-date. Poorly controlled early postoperative pain impairs quality of recovery, increases the risk of postoperative pulmonary complications, and is a risk factor for the subsequent development of chronic pain. Therefore, optimizing acute postoperative analgesia is a priority in patients undergoing bariatric surgery. The primary aim of this prospective, randomized study is to evaluate the effect of ESPB on quality of recovery with the QoR-40 questionnaire in patients undergoing elective Laparoscopic Bariatric Surgery.

Detailed Description

In the operating room, all patients will receive standard monitoring, including electrocardiography, non-invasive blood pressure, and peripheral oxygen saturation. Patients in the ESPB group will be placed in a sitting position. A convex probe ultrasound transducer will be placed in a longitudinal parasagittal orientation approximately 3 cm lateral to the spinous process. The needle tip was advanced until it will be located in the inter-fascial plane deep to the erector spinae muscle group and superior to the transverse process. Once in position, bupivacaine 0.25%, 20 ml was injected under ultrasound, guidance. The same procedure will be repeated on the contralateral site. Standard perioperative and postoperative analgesia protocol will be given and postoperative pain levels will be determined by Numerical Rating Scale (NRS). NRS scores for pain and postoperative opioid consumption will be recorded on the 15th,30th minute, 1st, 2nd, 12th, 24th hour, 2nd day. Quality of recovery-40 (QoR-40) scores will be given on the ward, at postoperative 24th hour, 3rd and 7th day ( the 3rd and 7th-day scores will be calculated after telephone interview if the patient will be discharged from the hospital).

GroupInterventionDescription
Group NPerioperative and postoperative multimodal analgesiaThe patients in Group N will not receive any intervention. Patients will receive standard multimodal analgesia comprising paracetamol, tenoxicam, and tramadol. The pain intensity will be evaluated with the 0-10 Numeric Rating Scale (NRS). NRS are the simple and most commonly used scales.11 The numerical scale is most commonly 0 to 10, with 0 being "no pain" and 10 being "the worst pain imaginable."
Group ESPBPerioperative and postoperative multimodal analgesiaThe patients in the group ESPB will be placed in sitting pozition. A convex probe ultrasound transducer will be place in a longitudinal parasagittal orientation about 3 cm lateral to spinous process. Local anesthetic (20 ml 0.25% bupivacaine) will be injected bilaterally into the fascial plane on the deep aspect of erector spinae muscle. Standard perioperative and postoperative analgesia protocol will be given and postoperative pain levels will be determined by Numerical rating scale (NRS)

Primary Outcome Measures
NameTimeMethod
Quality of Recovery (QoR-40) scorepostoperative 24th hour

QoR-40, a 40-item questionnaire that provides a global score and subscores across five dimensions: patient support, comfort, emotions, physical independence, and pain. Each item is rated on a scale of 1-5, providing a minimum score of 40 and maximum of 200. The increase in scores show high quality of recovery.

Secondary Outcome Measures
NameTimeMethod
mobilization timePostoperative 24 hour

The time after surgery to the mobilization of the patient

Sedation scorePostoperative 48 hour

Evaluation of the level of sedation in patients with a 4-point scale (0=wake, 1=sleepy, easy to verbally arouse, 2=drowsy, 3=does not open their eyes to verbal commands).

Postoperative pain: numeric rating scale (NRS)Postoperative 48 hour

NRS use numbers to rate pain from 0 (no pain) to 10 (worst pain). Postoperative pain levels will be determined by Numeric Rating Scale (NRS) system

Side effects24 hours

Rate of side-effect occurrences (such as rate of vomiting,nausea,dizziness)

Analgesic consumptionPostoperative 48 hour

Total opioid consumption at the postoperative period

Quality of Recovery (QoR-40) scorePostoperative 3rd and 7th days

QoR-40, a 40-item questionnaire that provides a global score and subscores across five dimensions: patient support, comfort, emotions, physical independence, and pain. Each item is rated on a scale of 1-5, providing a minimum score of 40 and maximum of 200. The increase in scores show high quality of recovery.

Postoperative complicationsPostoperative 30 days

Postoperative complications will be identified by visiting patients every day or alternate day during their in hospital course, suplemented by patients medical records using our hospital's electronic patient record database. We will use the Claviene Dindo Classification system from which CC is derived. We defined a postoperative complication as any deviation from the ideal postoperative course, not inherent in the procedure itself and does not constitute a failure to cure. CCI scores willbe calculated using the online CCI calculator.
