- Conditions
- Pain, Postoperative
- Interventions
- Registration Number
- NCT03242668
- Lead Sponsor
- Nguyen Trung Kien
- Brief Summary
To access the analgesic efficacy of patient controlled thoracic paravertebral analgesia.
- Detailed Description
The study was carried out on thirty patients who underwent video-assisted thoracic surgery.Paravertebral space was identified by loss of resistance technique under video-assisted inside thoracic space before chest close.Initiated dose of 0.3ml/kg of bupivacaine 0.125%+fentanyl 2 mcg/ml was administered then continued patient-controlled analgesia with background rate 3ml/h, bolus dose 2ml, lockout interval 10 minutes. Postoperative pain was accessed by Visual Analogue Scale at rest and on coughing; monitor the heart rate, blood pressure, respiratory rate, SpO2, arterial blood gas and spirometry in three postoperative consecutive days.

Group Intervention Description PVB using PVC for PCA in VATS PVB using PVC The VATS was performed.Paravertebral space was identified by loss of resistance technique combined with video-assisted inside thoracic space before chest close.PVC was inserted.Initiated dose of 0.3ml/kg of Bupivacaine Hydrochloride 1.25mg/ml and Fentanyl Citrate 2 micrograms/ml was administered then continued PCA with background rate 3ml/h, bolus dose 2ml was infused through PVC.

- Primary Outcome Measures
Name Time Method VAS score at rest and on coughing 72 hours Using VAS scale (Atrazennica)
- Secondary Outcome Measures
Name Time Method Arterial blood gas values three postoperative consecutive days Using Arterial blood gas analysis (STAT Model No.MCP9819-065, Martel Instruments Ltd)
The number dermatome inhibition three postoperative consecutive days Using pin-prick test
Rescue analgesia three postoperative consecutive days When VAS score equal to or more than 4 using fentanyl to manage pain
Analgesia effects on respiratory function three postoperative consecutive days Using Spirometry (Chestgraph H1 - 105,Japane) to evaluate respiratory index
Patient's satisfaction three postoperative consecutive days Using questionaire with 4 levels :not good,satisfied,good,very good
