| 释义 |
Blunt dissection describes the careful separation of tissues along tissue planes by either fingers or convenient blunt instruments during many diverse surgical procedures. Blunt dissection consumes a large proportion of time in most surgeries and has not changed significantly in centuries. It requires great skill, can be tedious, nerve-wracking, and risky. Repairs are often required {{Citation needed|date=January 2017}}. Blunt dissection is contrasted to sharp dissection, the practice of slicing through tissues with scalpels, scissors, electrosurgery, or other advanced technologies usually employing heat. New devices are expected to soon make blunt dissection safer, faster and easier{{Citation needed|date=January 2017}}. Use in pneumothoraxIt is one method employed prior to the insertion of a chest drain following a pneumothorax. Following incision above the rib (to avoid the neurovascular bundle), blunt dissection of the subcutaneous tissue, external, internal and innermost intercostal muscles allows access to the pleura.[1] Indeed, blunt dissection is now considered the favoured approach for the insertion of large bore chest tubes since it results in fewer complications.[2] References1. ^BTS guidelines for the insertion of a chest drain 2. ^Haggie JA.
