Postoperative pulmonary complications are a frequent cause of morbidity following lumbar stabilization surgery. Conventional ventilation strategies may not adequately reflect intraoperative changes in respiratory mechanics, potentially leading to impaired postoperative pulmonary function. Dynamic compliance-guided ventilation provides a real-time, individualized approach by adjusting ventilatory parameters according to lung compliance. This prospective randomized controlled study aims to evaluate the effects of dynamic compliance-guided ventilation compared with standard ventilation strategies on postoperative pulmonary function in patients undergoing lumbar stabilization surgery. Eligible patients will be randomly assigned to either the compliance-guided group or the conventional ventilation group. In this study, the investigators aim to prospectively compare ventilation with the dynamic compliance (Cdyn) approach-one of the lung-protective ventilation strategies-with conventional ventilation methods in patients undergoing surgery in the prone position. The primary outcome will be evaluated using a modified lung ultrasound scoring system based on the most severely affected regions of aeration loss. Secondary objectives include the assessment of intraoperative hemodynamics, respiratory mechanics, and the effects on postoperative pulmonary function.

The proposed research is an important extension of an ongoing perioperative personalized analgesia and intravenous opioid pharmacogenetic research. This research focuses on two of the most commonly used oral opioid analgesics, oxycodone, and methadone, in adults following lumbar spinal fusion and decompression surgery. Genetic signature and combinatorial pharmacogenetic approaches perform better than single-gene associations. This innovative translational research will for the first time evaluate simultaneously the effects of multiple genes and interactions on oxycodone and methadone's pharmacokinetics and optimal clinical dosing and on its safety and efficacy in the highly vulnerable pediatric population. This research's multigenetic signature findings can be easily extrapolated to adults undergoing surgery or using oxycodone and/or methadone for chronic and cancer pain and in identifying opioid abusers at risk of severe respiratory depression and death. When methadone is given in addition to oxycodone for inpatient pectus excavatum repair and idiopathic scoliosis spinal fusions according to new departmental protocols, methadone pharmacokinetics and pharmacodynamics will also be evaluated.
