A Retrospective Clinical Registry of Peripheral Nerve Block

Status Completed

Clinical Trial Summary

Clinical Trial Description

Locorregional anaesthesia have been increased its role in different kind of surgeries, alone or combined with general anesthesia. Due to ultrasound, peripheral nerve blocks have been increased their importance in locoregional anaesthesia. They provide excellent intraoperative and postoperative analgesia, decreasing the need for intravenous opioids which increase postoperative nausea and vomiting which may prolong hospital stay. However, peripheral nerve blocks may be associated with postoperative complications, especially neurological ones. Classically, interscalene brachial plexus block produced a 100% incidence of phrenic nerve paralysis with resultant pulmonary compromise. Little literature has published a following of complications. The primary study objective is to analyze retrospectively the use of peripheral nerve blocks in the current practice of a specialized regional anaesthesia division. The secondary objectives are assessed the patients characteristics of our sample, local anaesthetic dose used, the peripheral nerve block operator, the nerve location technique, the surgery and the complication rate after peripheral nerve block. This is an observational, retrospective and unicenter study. 1346 patients scheduled for the surgery needed a peripheral nerve block were enrolled. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
