Lung Cancer
Conditions
Brief summary
Local thermal ablation therapy of tumor is a rapidly developing minimally invasive therapy for lung tumors in recent years. This study evaluated the efficacy of thoracic paravertebral block (TPVB) for anaesthesia during ablation surgery of lung tumor.
Detailed description
Lung cancer is a serious threat to human health and life. Local thermal ablation therapy of tumor is the focus of domestic and overseas research in the past decade.Thoracic paravertebral nerve block (TPVB) is the technique of injecting local anaesthetic in the paravertebral space to anesthetizes the spinal nerve roots and sympathetic chain，which will produces ipsilateral and somatic blockade.The present study was designed to evaluate the analgesic effect and safety of TPVB in the ablation surgery of lung tumor. After obtaining approval from the Hospital Ethics Committee and informed written consent from the patients,30 adult patients scheduled for Local thermal ablation therapy of lung tumours were recruited. Patients were excluded if they had a history of psychiatric illness, chronic pain, regular analgesic usage or there were contraindications to performing a TPVB, such as chest wall deformity, severe coagulopathy, local infection and allergy to local anaesthetic drugs. The study lasted a total of six months. During the preoperative visit, all patients received the explanation of overall research approach.After entering the CT fluoroscopy room, peripheral veins and routine monitoring that included electrocardiography, pulse oximetry, and noninvasive arterial blood pressure were obtained in all patients.Thoracic paravertebral block was performed 20 minutes before the Local thermal ablation therapy began.The degree of pain was assessed using VAS score; at performing TPVB，the beginning of surgery， 6 and 24 hours after ablation surgery.Dezocine will be given as remedial analgesia.Following the operation, transferred the patients to the observation area where the vital signs were monitored for 30 min.Assessing and record the degree of patients and surgeons satisfaction for anesthetic management.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The degree of pain that patients feel who undergo ablation surgery is assessed by the visual analog scale (VAS). | During surgery | All patients are instructed on the use of the visual analog scale (VAS) for pain assessment before surgery, then anesthetist evaluate the analgesic effect of TPVB for the ablation surgery with the VAS during surgery(0=no painand 10=the worst pain). |
