Abstract

Objectives Thoracic surgery often causes postoperative delirium (POD) in geriatric patients. This study aimed to explore the effect of ultrasound-guided continuous thoracic paravertebral block (UG-TPVB) on POD in geriatric patients undergoing pulmonary resection.

Methods Total 128 patients who underwent pulmonary resection were randomly allocated to either the conventional patient-controlled analgesia (PCA) group or the UG-TPVB group (n = 64 per group). The consumption of opioid agents (propofol and remifentanil), postoperative hospital stay, postoperative pulmonary atelectasis, postoperative nausea/vomiting, and postoperative itchiness were recorded. The diagnosis of delirium was dependent on the Nursing Delirium Screening Scale. The postoperative pain was assessed by visual analogue scale (VAS) score. The serum levels of interleukin (IL)-1β, IL-6, and tumor necrosis factor-α were used to evaluate the postoperative neuroinflammation.

Results The consumption of propofol and remifentanil, postoperative hospital stay, postoperative pulmonary atelectasis, postoperative nausea/vomiting, and postoperative itchiness in the UG-TPVB group were lower than that in the PCA group. Compared with the PCA group, the prevalence of POD was decreased in the UG-TPVB group. In addition, use of UG-TPVB not only reduced postoperative pain (VAS score) but also decreased postoperative neuroinflammation compared with PCA in geriatric patients undergoing pulmonary resection.

Conclusions This study determined the benefits of UG-TPVB over PCA, providing an effectiveness approach to alleviate POD in geriatric patients undergoing pulmonary resection.
