A Comparison between Ultrasound Guided Erector Spinae Block Using Bupivacaine Versus Parasternal Nerve Block in Pediatric Patients Undergoing Cardiac Surgery for Post-Operative Pain Management after Median Sternotomy: A Randomized Controlled Double-Blinded Study

Background: Children of all ages experience pain. An explosion in pain research over the last decade has elucidated more clearly our understanding of pain mechanisms, appropriate pain assessment, and the safe applicaton of innovatve pharmacologic and non-pharmacologic strategies to treat pain in adults and children. In additon, we now understand that the negatve consequences of untreated pain may have profound efects on physiologic homeostasis, and in the case of the post-operatve patent, morbidity and mortality may be adversely afected, especially in the pediatric populaton undergoing major surgeries such as cardiothoracic surgeries. Aim of Study: The aim of this study was to compare the efficacy of Parasternal nerve vs Erector Spinae Plane Block in comparison with the control group. Patients and Methods: The study was conducted between June 2022 and January 2023 and was carried at the Cardiot-horacic Surgery Department operation theater. Patients scheduled for elective cardiac surgery for non cyanotic ASD & VSD repair were recruited in this randomized research. 3 Groups
