Comparison of Posterior Quadratus Lumborum Block vs Surgical Wound Infiltration in Patients Undergoing Bariatric Sleeve Gastrectomy Surgery.

Background: We are studying whether the performance of the posterior quadratus lumborum block (pQLB) will decrease postoperative opioid consumption in patients undergoing laparoscopic sleeve gastrectomy (LSG) compared with surgical wound infiltration with local anesthetic.

Methods: This is a single-center, prospective, randomized pilot study. Forty ASA 3 patients with severe obesity undergoing LSG were randomized to receive either the pQLB or surgical wound infiltration of local anesthetics.

Growing rods for scoliosis in spinal muscular atrophy: structural effects, complications, and hospital stays.

Study Design: Retrospective analysis of patients with spinal muscular atrophy (SMA) treated with growing rod (GR) instrumentation for scoliosis.

Objective: To evaluate structural effectiveness, complications, and length of hospital stay associated with GRs for scoliosis in SMA and to compare values with those of infantile and juvenile idiopathic scoliosis (IIS/JIS).

Summary Of Background Data: Most studies evaluate GR effectiveness in all patients.

Lengthening of dual growing rods and the law of diminishing returns.

Study Design: A retrospective multicenter study.

Objective: To evaluate the effect of repeated surgical lengthenings and time on spinal growth and Cobb angle in children with early onset scoliosis and dual growing rods.

Summary Of Background Data: Previous studies have established the effectiveness of dual growing rods for controlling spinal deformity and promoting spinal "growth.
