Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Postoperative pain following cardiac surgery is a common issue that can negatively impact patients' quality of life. Effective perioperative pain management is crucial to improving patient outcomes. Pain is typically most intense during the first two postoperative days, and inadequate management can lead to chronic pain, further diminishing quality of life. Recent advances in ultrasound-guided regional anesthesia, including superficial and deep parasternal intercostal plane blocks, have enhanced acute pain control. These blocks aim to provide analgesia by targeting the anterior cutaneous branches of the T2-6 thoracic nerves. While their efficacy is recognized, sensory evaluation and dermatomal analysis remain unexplored. Cadaver studies suggest that the deep block may cover more parasternal space than the superficial block.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This observational study evaluates sensory blocks in patients undergoing open-heart surgery who receive superficial or deep parasternal intercostal plane blocks. Sensory assessment, conducted by a blinded researcher 30 minutes post-block, involves applying small ice tubes with cold sensations categorized as Normal, Reduced, or No cold. A successful block is defined as the loss or reduction of cold sensitivity, while normal cold sensation indicates block failure. Assessments start at the midline, moving laterally to the anterior axillary line. Marked areas are digitally analyzed. Block regression is evaluated at 12 and 24 hours post-procedure using the same cold assessment criteria.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Deep Parasternal

Patients scheduled for open-heart surgery will receive a deep parasternal intercostal plane block preoperatively, and sensory block status will be evaluated 30 minutes later using small ice tubes.

Sensory Assessment

Intervention Type OTHER

Patients scheduled for open-heart surgery will receive a deep/superficial parasternal intercostal plane block preoperatively, and sensory block status will be evaluated after 30 minutes.

Superficial Parasternal

Patients scheduled for open-heart surgery will receive a superficial parasternal intercostal plane block preoperatively, and sensory block status will be evaluated 30 minutes later using small ice tubes.

Sensory Assessment

Intervention Type OTHER

Patients scheduled for open-heart surgery will receive a deep/superficial parasternal intercostal plane block preoperatively, and sensory block status will be evaluated after 30 minutes.
