1 Screening
During screening written informed consent will be obtained, inclusion & exclusion criteria will be checked, demographic data and vital signs will be recorded. Baseline questionnaires (QoR-15NL, EQ-5D-5L and BPI) will be obtained.
Not Applicable None
2 Randomization
Patient's eligibility criteria will be checked. Patient will be randomised by an unblinded member of the study team, not invloved in patient care. Patiens will be randomised in two groups
Randomised Controlled Double [{"id":144710,"code":5,"name":"Carer"},{"id":144712,"code":2,"name":"Investigator"},{"id":144711,"code":1,"name":"Subject"}] SPIP: The bilateral SPIP block with 40 mL trial drug solution is administered after skin closure. The trial drug solution contains ropivacaine, dosed according to the corresponding weight category, which is diluted with normal saline to a total volume of 40 mL. The trial drug solution volume will be divided into two 20 mL syringes. The labelling of the syringes will not display information in regard to the study medication it may contain nor the allocated treatment arm. After skin closure, the bilateral SPIP block will be performed by the (sub)-investigator with the use of a linear, high-frequency ultrasound probe. Ultrasound images of each separate LA administration will be stored. The SPIP block is first performed on the left hemithorax. At the level of the 2nd intercostal space (ICS), 2-3 cm lateral to the sternal bone, the pectoralis major muscle (PMM) and the external intercostal muscle (exIM) are identified. The needle is positioned in the fascial plane between the PMM and the exIM, and correct positioning is confirmed by hydro-dissection of this fascial plane with 2 mL of normal saline 0.9%. In this fascial plane, 6 ml trial drug solution is injected. Consecutively, this is repeated at the 4th and 5th ICS, administering 7 mL of trial drug solution at these sites. This exact procedure is replicated on the right hemithorax.
Control: The bilateral SPIP block with 40 mL Normal saline 0.9% is administered after skin closure. The 40 ml Normal saline 0.9% will be divided into two 20 mL syringes.

3 Follow-up
3h-6h-12h post operative pain scores will be checked Postoperative day 1 -2 and 3: pain scores will be checked, patient will be asked to complete QoR-15 and EQ-5D-5L questionnaires; 30 day post surgery: completion of the EQ-5D-5L questionnaire during phone call

  2. At least 18 years of age at the time of signing the Informed Consent Form
  3. Patients scheduled for cardiac surgery via conventional median sternotomy.
  4. Patients with an European System for Cardiac Operative Risk Evaluation (EuroSCORE) 2 ≤ 3 %.
  5. Dutch speaking

Exclusion criteria 8

  1. Participation in an interventional Trial with an investigational medicinal product (IMP) or device
  2. BMI > 35
  3. Patients with a bodyweight below 50 kg or exceeding 95 kg.
  4. An adult who is incapable or unable to give consent (e.g. curatorship, guardianship, language barrier,…).
  5. Patients requiring emergency surgery within 24 hours.
  6. Patients with chronic pain (i.e., chronic opioid use or other analgesics)
  7. Any disorder or medical condition, which in the principle investigator’s opinion, would jeopardise the patient’s safety or compliance with the trial. (allergies, concomitant drugs that interact with the IMP
  8. If applicable: Female who is pregnant, breast-feeding or intends to become pregnant or is of child-bearing potential and not using an adequate, highly effective contraceptive. Women of child-bearing potential (WOCBP) should only be included after a confirmed menstrual period and urinary pregnancy test. Participants are considered not of childbearing potential if they are surgically sterile (i.e. they have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are postmenopausal, defined as no menses for 12 months without an alternative medical cause.

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. The primary outcome is the mean difference in QoR-15NL score between the verum bilateral SPIP block (intervention group) and the placebo bilateral SPIP block (control group) in patients undergoing cardiac surgery via conventional median sternotomy on the first postsurgical day, defined as 24 hours after surgical incision, assessed by the Dutch Quality of Recovery 15 items questionnaire.

Secondary endpoints 10

  1. The cumulative opioid consumption in the first 72 hours after surgical incision
  2. Time to first rescue analgesia for breakthrough pain (e.g. oxycodone or piritramide) in the first 72 hours after surgical incision (in minutes).
  3. The AUC of the reported dynamic NRS scores at predefined timepoints (assessed at 3, 6, 12, 24, 48, 72 hours) during the first 72 hours after surgical incision.
  4. The AUC of the reported dynamic NRS scores at predefined timepoints (assessed at 3, 6, 12, 24, 48, 72 hours) during the first 72 hours after surgical incision.
  5. Number of patients with PONV in the first 24 hours after surgical incision
  6. Time spent in the ICU/PACU until fit for discharge (in hours).
  7. Time spent in the hospital between surgical incision and the first hospital discharge (in hours).
  8. Occurrence of respiratory complications, leading to non-invasive ventilation (NIV) or high-flow nasal cannula (HFNC) oxygen therapy, orotracheal intubation for more than 24 hours or orotracheal re-intubation
  9. QoR-15NL score on the second (D2) after surgery
  10. EQ-5D-5L score 30 days after surgery
