Blok Serratus přední plány (SAP) a Pectoralis Blocks (PECS I-II) po operaci otevřeného srdce
Aplikace Serratus přední plán (SAP) a Pectoralis (PECS I-II) po operaci otevřeného srdce
This prospective randomized placebo-controlled trial was designed to evaluate the effects of ultrasound-guided bilateral pectoralis (PECS II) and serratus anterior plane (SAP) blocks on postoperative recovery in adult patients undergoing elective coronary artery bypass grafting (CABG). Patients were randomized to receive bilateral PECS II block, bilateral SAP block, or bilateral sham fascial plane injections in addition to standardized systemic analgesia. The study evaluated postoperative pain intensity using the Visual Analog Scale (VAS), opioid consumption, postoperative nausea and vomiting (PONV), block-related complications, duration of mechanical ventilation, time to first mobilization, and intensive care unit (ICU) length of stay.

Detailní popis
This prospective, randomized, placebo-controlled trial evaluated the postoperative analgesic efficacy of ultrasound-guided bilateral serratus anterior plane (SAP) block and bilateral PECS II block in adult patients undergoing elective coronary artery bypass grafting (CABG). Participants were randomly assigned to one of three groups: bilateral SAP block, bilateral PECS II block, or bilateral sham fascial plane injections (placebo comparator). All participants received the same standardized postoperative systemic analgesic regimen.
To preserve allocation concealment and blinding, an investigator not involved in patient management prepared identical coded syringes according to the randomization sequence. The physician performing the ultrasound-guided procedures was unaware of syringe contents. All participants underwent bilateral injections at both the PECS II and SAP fascial planes; depending on group allocation, each fascial plane received either 0.25% bupivacaine or 0.9% saline. Postoperative outcome assessment was performed by investigators blinded to treatment allocation.
The primary outcome was postoperative pain intensity measured using the Visual Analog Scale (VAS) at predefined time points after extubation. Secondary outcomes included cumulative opioid consumption during the first 24 postoperative hours, postoperative nausea and vomiting (PONV), and block-related complications. Additional recovery-related outcomes included duration of mechanical ventilation, time to first mobilization, and intensive care unit (ICU) length of stay. These recovery outcomes were analyzed as exploratory endpoints because important perioperative factors influencing recovery were not systematically collected.

Experimentální: Bilateral SAP Block
Participants undergoing elective coronary artery bypass grafting received an ultrasound-guided bilateral serratus anterior plane (SAP) block using 20 mL of 0.25% bupivacaine on each side. To maintain study blinding, ultrasound-guided placebo injections consisting of 20 mL of 0.9% saline were also administered bilaterally at the PECS II injection sites using identical coded syringes. |
Ultrasound-guided bilateral serratus anterior plane (SAP) block performed using 20 mL of 0.25% bupivacaine on each side after ICU admission while patients remained intubated following elective coronary artery bypass grafting. |

Aktivní komparátor: Bilateral PECS II Block
Participants undergoing elective coronary artery bypass grafting received an ultrasound-guided bilateral PECS II block using 20 mL of 0.25% bupivacaine on each side. To maintain study blinding, ultrasound-guided placebo injections consisting of 20 mL of 0.9% saline were also administered bilaterally at the serratus anterior plane injection sites using identical coded syringes. |
Ultrasound-guided bilateral PECS II block was performed using the standard two-injection technique after ICU admission while patients remained intubated following elective coronary artery bypass grafting. On each side, a total of 20 mL of 0.25% bupivacaine was injected between the pectoralis major and minor muscles and between the pectoralis minor and serratus anterior muscles. |

Komparátor placeba: Sham Block
Participants undergoing elective coronary artery bypass grafting received ultrasound-guided bilateral placebo injections consisting of 20 mL of 0.9% saline on each side at both the PECS II and serratus anterior plane injection sites using identical coded syringes to maintain study blinding. All participants received the same standardized postoperative systemic analgesic regimen. |
Ultrasound-guided bilateral sham fascial plane procedure was performed after ICU admission while patients remained intubated following elective coronary artery bypass grafting.
