Abstrakt: Objective: This study aimed to observe the impact of Tthoracic paravertebral nerve blockade(TPVB) at left T7 level on the α7nAChR-dependent cholinergic anti-inflammatory pathway in patients undergoing thoracoscopic lobectomy.
Methods: Scheduled thoracoscopic lung surgery patients at the First Affiliated Hospital of Nanchang University from August to September 2023 were divided into two groups according to the surgical site. The experimental group underwent left T7 paravertebral nerve blockade (LTPVB group), while the control group underwent right T7 paravertebral nerve blockade (RTPVB group). Relevant clinical data were collected, and Doppler ultrasound was used to measure the resistive index (RI) of the splenic artery before and after blockade. Additionally, perioperative α7nAChR levels and the expression levels of the inflammatory factors IL-1β, IL-6, and TNF-α were determined.
Results: There were no significant differences in general conditions, perioperative blood pressure, heart rate, or pain VAS scores between the two groups (p > 0.05). Splenic Doppler ultrasound showed that compared to before blockade, the RI of the splenic artery in the LTPVB group significantly decreased (p < 0.05). The α7nAChR levels at 12 h and 24 h postoperatively were significantly increased (p < 0.05) in both groups, and the levels of IL-1β, IL-6, and TNF-α gradually increased over time in both groups. However, the levels were significantly lower in the LTPVB group compared to the RTPVB group at 12 h and 24 h postoperatively (p < 0.05).
Conclusion: TPVB at left T7 can activate the α7nAChR-dependent cholinergic anti-inflammatory pathway, thereby alleviating the postoperative inflammatory response in patients undergoing thoracoscopic lobectomy.
