Summary

Postoperative cough after pulmonary resection is a common issue seen after thoracic surgeries, hindering patients' recovery and affecting their postoperative quality of life. While vagus nerve pulmonary branch block has been known to reduce intraoperative coughing, its impact on postoperative cough post lung resection is uncertain. This study aims to assess the effects of vagus nerve pulmonary branch block on postoperative cough after VATS lung resection. A randomized controlled trial involving 104 thoracoscopic lung resection patients will assign them randomly to a vagus nerve pulmonary branch block group or a control group. The primary outcome measure is the postoperative cough incidence 3 weeks after lung resection. The secondary outcomes include assessing hoarseness in PACU, peak expiratory flow (PEF) on the first post-op day, NRS scores for cough, and LCQ-MC scores at 3 weeks post-surgery, as well as cough occurrence, NRS scores, and LCQ-MC scores at 8 weeks post-procedure.

Conditions

  • Postoperative Cough
  • Thoracoscopy
  • Pulmonary Resection
  • Vagus
  • Nerve Block

Interventions

PROCEDURE

Vagus Nerve Pulmonary Branch Block

Following thoracotomy, the thoracic surgeon, under direct thoracoscopic guidance, used forceps to elevate the apex of the lung, thus exposing the main trunk of the pulmonary branches of the vagus nerve. The injection needle was then advanced from a lateral-to-medial direction, and 2.5 ml of 0.375% ropivacaine was administered in close proximity to the targeted vagal branch.

PROCEDURE

Vagus Nerve Pulmonary Branch Injection

Following thoracotomy, the thoracic surgeon, under direct thoracoscopic guidance, used forceps to elevate the apex of the lung, thus exposing the main trunk of the pulmonary branches of the vagus nerve. The injection needle was then advanced from a lateral-to-medial direction, and 2.5 ml of normal saline was administered in close proximity to the targeted vagal branch.
