<p>Characteristics of Postoperative Pain After VATS and Pain-Related Factors: The Experience in National Cancer Center of China</p>

Abstract

Patients seemed to experience a lower incidence of acute severe pain and CPSP after VATS than traditional open surgery. Acute severe pain was correlated with smoking history, VATS type, operation time, and PCA; VATS type, operation time, duration of drainage, and severe pain on the 1st day postoperatively were four independent risk factors of CPSP.
