About

To access the analgesic efficacy of patient controlled thoracic paravertebral analgesia.

Full 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.
