Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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. | — |
