We present a case of persistent phrenic nerve paralysis after a successful interscalene brachial plexus block. In addition, there was no observed diaphragmatic stimulation, and the patient underwent an uneventful early postoperative period. Warning signs of a complication were either missed or absent until several days after discharge from the ambulatory surgical unit.

Clinical TrialVertical infraclavicular brachial plexus block in children: a preliminary study.
Brachial plexus blockade is a well-established technique in upper limb surgery. Among the infraclavicular approaches, the vertical infraclavicular brachial plexus (VIP) block is easy to perform and has a large spectrum of nerve blockade. The aim of this preliminary study was to determine the ease, effectiveness, safety, and duration of the VIP block in pediatric trauma surgery. ⋯ In this preliminary study, the VIP block was easy to perform, effective and free of major complications for pediatric trauma surgery. With the doses of ropivacaine we used it was useful for intra- and postoperative analgesia.

Randomized Controlled Trial Clinical TrialMedian versus musculocutaneous nerve response with single-injection infraclavicular coracoid block.
Local anesthetic injection after elicitation of a distal motor response with a nerve stimulator is believed to produce a more clinically efficient infraclavicular coracoid block than after elicitation of a proximal motor response. The aim of this study was to investigate whether elicitation of a median or of a musculocutaneous-type nerve response influenced the quality of anesthesia. ⋯ Elicitation of a median nerve response improved the efficacy of infraclavicular coracoid block when compared with a musculocutaneous nerve response. Complete paralysis and complete anesthesia of the upper limb were low in both groups.

Malingering is not a diagnosis. It is a behavior for which there are no established diagnostic criteria. Guidelines have been published according to which malingering might be suspected, but those guidelines do not discriminate between patients who are malingering and ones with genuine sources of chronic pain. ⋯ Negative responses do not exclude a genuine complaint of pain, for patients may have a source of pain that is not amenable to testing with diagnostic blocks. Diagnostic blocks have proved particularly useful in the investigation of spinal pain for which the cause is not evident on conventional medical imaging. They can also confirm or refute purported mechanisms of certain clinical features in complex regional pain syndromes.
