Combined transversus thoracic + serratus anterior plane blocks versus erector spinae plane block for pain after sternotomy

STERNOTOMİ AĞRISININ YÖNETİMİNDE TRANSVERSUS TORASİK PLAN BLOK VE SERRATUS ANTERİOR PLAN BLOK KOMBİNASYONU İLE EREKTÖR SPİNA PLAN BLOK ETKİNLİĞİNİN KARŞILAŞTIRILMASI

Not applicable Interventional Uludag University · NCT07452627

This trial will try whether combining transversus thoracic and serratus anterior plane nerve blocks controls pain after median sternotomy better than an erector spinae plane block in adults having elective heart surgery.

What this trial studies

This is a prospective, randomized, observer-blinded trial enrolling 50 adults (age 18–80, ASA I–III) undergoing elective median sternotomy for cardiac surgery. Participants are randomized 1:1 to receive either combined transversus thoracic plane block (TTPB) plus serratus anterior plane block (SAPB) or a single erector spinae plane block (ESPB), performed under ultrasound guidance after induction and before incision. Anesthesia and perioperative care are standardized and postoperative data collectors are blinded to the allocated block to reduce bias. Primary outcomes focus on postoperative pain control and opioid requirements, with monitoring for respiratory and other complications.

Who should consider this trial

Good fit: Adults aged 18–80 with ASA physical status I–III scheduled for elective cardiac surgery via median sternotomy who can give informed consent and have no contraindications to regional anesthesia.

Not a fit: Patients who are pregnant, have BMI >35 kg/m², coagulopathy, infection at the injection site, allergy to local anesthetics, or severe neurological/psychiatric/hepatic/renal failure were excluded and are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the combined block approach could reduce postoperative sternotomy pain and opioid use, potentially improving recovery and lowering pulmonary complications.

How similar studies have performed: Regional chest wall blocks such as ESPB and SAPB have shown promising pain-reducing effects in small trials, but combining TTPB with SAPB for sternotomy pain is less well studied and remains relatively novel.
