Figure 3: Approximate representation of the extent of cutaneous sensory loss over the left anterolateral thorax with the upper limb in adduction. A sensitive block was administered to the level of C5–C6. This sensitive block lasted 4–6 h after the initial bolus of 0.375% ropivacaine (20 mL) was administered at T4, deep in the erector spinae muscle. The yellow area represents diminished pinprick and thermal sensation. The red area represents a discrete area of diminished cold sensation in the region of the lateral antebrachial nerve
