ESPB Versus Combined PIPB and RIB for Analgesia in Minimally Invasive Cardiac Surgery

9 novembre 2026 aggiornato da: Ankara Etlik City Hospital

Comparison of the Postoperative Analgesic Efficacy of Combined Parasternal Intercostal Plane and Rhomboid Intercostal Blocks Versus Erector Spinae Plane Block in Minimally Invasive Cardiac Surgery: A Prospective Randomized Controlled Trial

Pain after minimally invasive cardiac surgery can affect breathing, movement, and recovery. Regional anesthesia techniques may help reduce postoperative pain and the need for opioid pain medications.

This study aims to compare two ultrasound-guided regional anesthesia approaches for pain management after minimally invasive cardiac surgery: erector spinae plane block (ESPB) and a combination of parasternal intercostal plane block (PIPB) and rhomboid intercostal block (RIB).

A total of 56 adult patients undergoing minimally invasive cardiac surgery will be randomly assigned to one of two groups. One group will receive ESPB, while the other group will receive the combined PIPB and RIB technique. Both approaches will use the same total dose of local anesthetic and will be performed after induction of general anesthesia and before surgery.

The main objective is to compare how pain scores at rest change between the two groups during the first 12 hours after removal of the breathing tube. Pain will be assessed using a numerical scale from 0 (no pain) to 10 (worst imaginable pain).

The study will also evaluate postoperative opioid consumption, additional pain measurements, quality of recovery, and block-related adverse events. Quality of recovery will be assessed using the QoR-15T questionnaire before surgery and 48 hours after extubation.Patient-reported acceptability of postoperative pain management will also be evaluated using a Likert scale at 48 hours postoperatively.

The findings may help identify effective regional anesthesia strategies for postoperative pain management in minimally invasive cardiac surgery.

Descrizione dettagliata

Postoperative pain management is an important component of enhanced recovery after minimally invasive cardiac surgery (MICS). Although minimally invasive approaches avoid conventional median sternotomy, patients may experience substantial pain related to the thoracic incision, intercostal tissue injury, and chest drains.

Ultrasound-guided regional anesthesia techniques are increasingly used as part of multimodal analgesia in cardiac surgery. The erector spinae plane block (ESPB) is a fascial plane block that may provide analgesia through the spread of local anesthetic across multiple thoracic segments. The combined parasternal intercostal plane block (PIPB) and rhomboid intercostal block (RIB) approach targets different regions of the thoracic wall and may provide complementary analgesic coverage.

This prospective, single-center, randomized controlled trial will compare the postoperative analgesic efficacy of unilateral ESPB with combined PIPB and RIB in 56 adult patients undergoing minimally invasive cardiac surgery.

Following induction of general anesthesia and before surgical incision, patients will receive one of two ultrasound-guided regional anesthesia approaches. The ESPB group will receive 30 mL of 0.25% bupivacaine on the surgical side. The combined-block group will receive 15 mL of 0.25% bupivacaine for PIPB and 15 mL of 0.25% bupivacaine for RIB. The total local anesthetic dose will be identical between groups.

All patients will receive standardized perioperative care and multimodal postoperative analgesia, including acetaminophen and patient-controlled tramadol analgesia.

The primary outcome will be the between-group difference in the trajectory of resting Numeric Rating Scale (NRS) pain scores at 0, 2, 4, 8, and 12 hours after extubation, evaluated through the group-by-time interaction.

Secondary outcomes will include postoperative pain measurements at additional time points, cumulative tramadol consumption during the first 24 hours, time to first rescue analgesia, postoperative quality of recovery assessed using the Turkish version of the Quality of Recovery-15 questionnaire (QoR-15T),Patient-reported acceptability of postoperative pain management will also be assessed using a Likert scale at 48 hours postoperatively and block-related adverse events.

The study aims to determine whether the combined PIPB and RIB approach offers a clinically useful alternative to ESPB for postoperative analgesia after minimally invasive cardiac surgery.

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Postoperative Resting Pain Scores Assessed by the Numeric Rating Scale (NRS)
Lasso di tempo: At 0, 2, 4, 8, and 12 hours after extubation

Postoperative pain intensity at rest will be assessed using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain). Measurements will be obtained at 0, 2, 4, 8, and 12 hours after extubation. The primary outcome will be the group-by-time interaction in resting NRS scores, comparing the erector spinae plane block (ESPB) group with the combined parasternal intercostal plane block and rhomboid intercostal block (PIPB + RIB) group using a repeated-measures statistical approach.

At 0, 2, 4, 8, and 12 hours after extubation

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Cumulative Postoperative Tramadol Consumption Within 24 Hours
Lasso di tempo: From extubation to 24 hours after extubation

Total tramadol consumption (mg) during the first 24 hours after extubation will be recorded. Postoperative patient-controlled analgesia (PCA) will be provided using tramadol with a 10 mg bolus dose, a 10-minute lockout interval, and no basal infusion. Cumulative tramadol consumption will be compared between the ESPB and combined PIPB + RIB groups. Higher consumption indicates greater postoperative opioid requirements.

From extubation to 24 hours after extubation
Postoperative Pain Score at Rest at 24 Hours
Lasso di tempo: 24 hours after extubation

Postoperative pain intensity at rest will be assessed using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain). Pain scores will be recorded at 24 hours after extubation and compared between the ESPB and combined PIPB + RIB groups. Higher scores indicate greater pain intensity.

24 hours after extubation
Change in Quality of Recovery-15 Turkish Version (QoR-15T) Score
Lasso di tempo: Preoperatively (baseline) and 48 hours after extubation

Quality of postoperative recovery will be assessed using the validated Turkish version of the 15-item Quality of Recovery questionnaire (QoR-15T). The questionnaire evaluates five domains: pain, physical comfort, physical independence, psychological support, and emotional state. Each item is scored from 0 to 10, yielding a total score ranging from 0 to 150, with higher scores indicating better recovery quality. The QoR-15T will be administered preoperatively and at 48 hours after extubation. The change in total score from baseline to 48 hours will be compared between the ESPB and combined PIPB + RIB groups.

Preoperatively (baseline) and 48 hours after extubation
Patient-Reported Acceptability of Postoperative Pain Management at 48 Hours
Lasso di tempo: 48 hours after extubation

Patient-reported acceptability of postoperative pain management will be assessed using a five-point Likert scale at 48 hours after extubation. Patients will rate their agreement with the statement, "The level of pain I experienced after surgery was acceptable to me." Responses will be scored as follows: 1 = Strongly disagree, 2 = Disagree, 3 = Neither agree nor disagree, 4 = Agree, and 5 = Strongly agree. Higher scores indicate greater acceptability of postoperative pain management. The distribution of responses will be compared between the ESPB and combined PIPB + RIB groups.

48 hours after extubation
Time to First Rescue Analgesia
Lasso di tempo: Within 24 hours after extubation

Time elapsed from extubation to the first administration of rescue analgesia, measured in minutes.

Within 24 hours after extubation
Incidence of Block-related Adverse Events
Lasso di tempo: Within 24 hours after block administration

Number of participants experiencing block-related adverse events, including pneumothorax and local anesthetic systemic toxicity.

Within 24 hours after block administration
Postoperative Pain Score During Movement at 24 Hours
Lasso di tempo: 24 hours after extubation

Postoperative pain intensity during movement will be assessed using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain). Pain scores will be recorded at 24 hours after extubation and compared between the ESPB and combined PIPB + RIB groups. Higher scores indicate greater pain intensity.
