Improvement and application of supine position components for lung tumor microwave ablation.

Abstract

Objective: This study aimed to evaluate the safety and efficacy of improved supine positioning components for lung tumor microwave ablation (MWA), with the goal of enhancing surgical efficiency, reducing complications, and improving patient experience.

Materials and methods: One hundred patients undergoing MWA for lung tumors were randomly divided into two groups (n = 50 each): experimental (using improved components) and control (using traditional components). The improved positioning system included a high-density memory foam head pillow, lumbar and leg pillows, and adjustable fixing bands tailored to individual patient needs. A comparative analysis was performed on the positioning time, surgical localization time, number of intraoperative computed tomography (CT) scans, changes in vital signs, incidence of postoperative complications, and patient satisfaction between the groups.

Results: The experimental group showed significantly shorter positioning (9.48 ± 1.79 min) and surgical localization times (15.08 ± 2.76 min) compared to the control group (P < 0.05). They also required fewer intraoperative CT scans and exhibited more efficient surgical procedures. The experimental group demonstrated a smaller fluctuation range in vital signs and a significantly lower incidence of hypoxemia (P < 0.05), indicating enhanced intraoperative safety in the experimental group. Additionally, the experimental group showed lower pneumothorax and hemothorax rates and higher postoperative patient satisfaction scores (P < 0.05).

Conclusion: The use of improved positioning components during MWA for lung tumors effectively reduces positioning time, improves surgical efficiency, lowers intraoperative complication risks, and enhances patient satisfaction. Thus, their application may be recommended for lung tumor MWA.
