Randomized Controlled Trial Clinical TrialPostoperative pain relief in children from the parascalene injection technique.
Nineteen pediatric patients aged 6 months to 12 years scheduled for elective upper extremity surgery were randomly assigned to receive either a parascalene block or sham injection. Both groups received a potent inhalational agent for operative anesthesia. ⋯ Patients in the parascalene group had superior postoperative analgesia, as evidenced by significantly less opioid requirement in the first 12 postoperative hours and by significantly lower scores on an objective pain scale. We found the parascalene approach to the brachial plexus a simple and reliable analgesic technique in anesthetized children.

Review[Mechanism of action and clinical use of opioids administered by the peripheral perineural route].
Experimental studies have shown that opioids could produce two types of effect on neuronal excitability. The first one, aspecific, is a local anesthetic action on the nerve fiber with a diminution of sodium and potassium conductance. ⋯ Clinical studies have proved that opioid injection in peripheral nervous trunks and specially in the brachial plexus produce a prolonged analgesia status in the post operative period but also and mostly in the chronic pain. The more liposoluble opioids like fentanyl and buprenorphine are the more effective.

A number of chronic pain syndromes in the perineal area can be related to pudental nerves suffering. The constancy of symptoms among various patients, and in duration for a particular one, alterations revealed by electrophysiologic studies, pain relief by diagnostic blocks, data from anatomic studies, preliminary results of medical and surgical applied therapies, give consistent arguments for possible organic lesions of pudental nerves.

Randomized Controlled Trial Clinical Trial
Continuous extrapleural intercostal nerve block after pleurectomy.
A randomised, double blind trial was carried out in 16 patients undergoing pleurectomy to assess the effect of continuous extrapleural intercostal block on postoperative pain and pulmonary function. Subjective pain relief was assessed on a linear visual analogue scale. Pulmonary function was measured on the day before operation and daily for five days after surgery. ⋯ The speed of recovery of pulmonary function was superior in the bupivacaine group. There were no complications related to the infusion. Continuous extrapleural intercostal nerve blockade with bupivacaine provides safe and effective postoperative analgesia and improves respiratory mechanics after pleurectomy.

This study included 20 children (average 8.5 years) undergoing surgery of the upper limb under brachial plexus block. A method of blocking the brachial plexus using an infraclavicular approach is described. Eighteen brachial plexus block were performed under general anesthesia. ⋯ Post-operative analgesia was satisfactory in all cases. In 10 cases a nerve stimulator was used. It is not necessary for the realization of a brachial plexus block, but the punction is easier under general anesthesia with this instrument.
