Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To compare execution time of ultrasound guided supraclavicular block in In-plane vs out-of-plane techniques for upper limb surgeriesTimepoint: Execution time: Time taken to perform the procedure. Time between needle entry into skin till deposition of local anaesthetic through block needle. | — |
Secondary
| Measure | Time frame |
|---|---|
| Association of the BMI and depth of plexus with the execution time of the block.Timepoint: BMI and depth of plexus will be recorded and correlated with the execution time individually;Block SuccessTimepoint: It will be defined based on success of obtaining composite sensorimotor score of equal or more than 14 points out of a total of 16 points at 30 minutes after depositing local anaesthetic via block needle;ComplicationsTimepoint: Complications such as vascular puncture, local anaesthetic systemic toxicity, nerve injury, pneumothorax, Hornerâ??s syndrome & recurrent laryngeal nerve palsy will be recorded up until 24 hours post injection of local anaesthetic;Duration of analgesiaTimepoint: VAS scores will be measured & Inj. Pethidine 20mg will be given as rescue analgesic when post op VAS score more than 6. VAS scores will be assessed at 2, 4, 6, 8 & 10 hours after injection local anaesthetic. Duration of analgesia will thus be measured based on need of rescue analgesic.;Number of needle passesTimepoint: Number of times the block needle needs to be retracted to skin and redirected while performing the block.;Onset of composite sensorimotor blockTimepoint: Sensory block of the musculocutaneous median radial & ulnar nerves will be assessed & graded as 0-normal sensation 1-loss of sensation to pinprick 2-loss of sensation to light touch compared with the normal contralateral limb. Motor block of same nerves will be tested & graded as 0-no block 1-paresis 2-paralysis. This will be assessed at 5, 10, 15, 20, 25 & 30 minutes till atleast 14 points out of 16 points is obtained after local anaesthetic injection. | — |
