简要总结
The purpose of this study is to determine if Peripheral Nerve Block scoring systems are effective in predicting the achievement of intra-operative anaesthesia and post-operative analgesia.
详细描述
Upper and lower extremity surgery is particularly suited to regional anaesthesia. Peripheral nerve blocks (PNB) can produce surgical anaesthesia in less than 30 minutes. PNBs have been associated with early outcome improvements when surgery is conducted awake or with light sedation. These benefits include reduced nausea and vomiting, improved patient satisfaction and accelerated recovery room and hospital discharge. PNBs can also provide effective postoperative pain relief. Currently there is no globally accepted standard by which to assess when surgical anaesthesia has been achieved following administration of PNBs. The decision as to when adequate surgical anaesthesia has been achieved and when surgery can then proceed is usually left to the discretion of the anaesthetist. The anaesthetist can assess nerve blockade though several motor and sensory function tests: cold, heat, touch and pinprick sensitivity. Several scoring systems have been described using these tests to estimate when surgical anaesthesia has been achieved but none have been independently validated outside of the original studies in which they have been described.
