A study of the paravertebral anatomy for ultrasound-guided posterior lumbar plexus block.
We investigated the feasibility of posterior paravertebral sonography as a basis for ultrasound-guided posterior lumbar plexus blockades. Posterior paravertebral sonography proved to be a reliable as well as accurate imaging procedure for visualization of the lumbar paravertebral region except the lumbar plexus.

Randomized Controlled Trial Clinical Trial
Intercostal nerve block with Bupivacaine for post-thoracotomy pain relief in children.
The purpose of the study is to evaluate the efficacy of Intercostal Nerve Block (ICB) with Bupivacaine (BUP) to produce satisfactory analgesia after thoracotomy in children. We studied 20 children aged between 5 and 12 years, scheduled for thoracotomy under general anaesthesia. The children were randomly divided into two groups. ⋯ The mean duration of postoperative analgesia produced was longer in the BUP group (p < 0.001). None of the children in BUP group suffered from BUP toxicity, while in the control group a high incidence of vomiting and nausea was noticed (p < 0.005). It is concluded that ICB with BUP produces satisfactory and safe analgesia for the early postoperative period after thoracotomy in children.

Randomized Controlled Trial Comparative Study Clinical TrialAnesthetic efficacy of unilateral and bilateral inferior alveolar nerve blocks to determine cross innervation in anterior teeth.
The purpose of this prospective randomized study was to measure the degree of anesthesia obtained with unilateral and bilateral inferior alveolar nerve blocks to determine whether cross innervation occurs in anterior teeth. ⋯ Cross innervation does seem to occur in mandibular central and lateral incisors. However, the success rates in these teeth with bilateral inferior alveolar nerve blocks were below 75%. The failure of the inferior alveolar nerve blocks to anesthetize the anterior teeth was the overriding reason for failure. Clinically, bilateral inferior alveolar nerve blocks to provide profound pulpal anesthesia in mandibular anterior teeth are not recommended on the basis of the results of this study.

Case Reports
Ipsilateral thoraco-lumbar anaesthesia and paravertebral spread after low thoracic paravertebral injection.
We report ipsilateral thoraco-lumbar anaesthesia and paravertebral spread of contrast after injection through a thoracic paravertebral catheter that was placed at the right T8-9 spinal level for pain management in a patient with multiple fractured ribs. We review the literature and describe the subendothoracic fascial communication between the thoracic paravertebral space and the retroperitoneal lumbar paravertebral region, which we propose, is the anatomical basis for ipsilateral thoraco-lumbar anaesthesia and paravertebral spread of contrast in our patient.
