- Primary Outcome Measures
Name Time Method The primary outcome measure is to assess the success rate / failure rate of thoracic paravertebral block placement. The block will be considered a success if surgery can be performed under the block. The block will be considered a failure if more than two dermatomes are missed after 60 minutes of conclusion of the block and general anaesthesia needs to be administered for the surgery.Timepoint: The assessment will be performed the first time at 20 minute after block administration. The assessment will be repeated every 10 minutes for upto 60 minutes after block placement.
- Secondary Outcome Measures
Name Time Method Comparison in between the two groups <br/ ><br>1.The nerve segments successfully blocked by the two techniques. <br/ ><br>2.The time required to perform the TPVB by the two techniques. <br/ ><br>3.The analgesic boluses needed intraoperatively in patients operated under by the two techniques of TPVB. <br/ ><br>4.The time for first analgesic requirement between by the two techniques of TPVB. <br/ ><br>5.The complications observed in patients operated under by the two techniques.Timepoint: For intraoperative and 24 hours postoperative period.
