Analgesic Efficacy of Multiple Mid-Transverse Process to Pleura (MTP) Block and PCA in Idiopathic Scoliosis Patients Undergoing Posterior Spinal Fusion

Patients will receive multiple mid-transverse process to pleura (MTP) block after induction of anesthesia.

Patients will receive IV-PCA. Morphine is generally administered as an initial loading dose of 0.05-0.1 mg/kg before the end of surgery, with PCA settings of a bolus dose of 0.01-0.03 mg/kg, a lockout interval of 6-10 min, and a background infusion of 0.01-0.02 mg/kg/h.
