Selective diagnostic cervical nerve root block--correlation with clinical symptoms and MRI-pathology.
The aim of this study is to describe the method of a cervical selective diagnostic nerve root block (SNRB) technique and assess its ability to correlate clinical symptoms with MRI findings in patients with cervical radicular pain and a single level degenerative disease. ⋯ The block procedure seems relevant for revealing a relationship between radiological pathology and clinical symptoms and signs.

Randomized Controlled Trial Clinical Trial
Varying anatomical injection points within the thoracic paravertebral space: effect on spread of solution and nerve blockade.
The factors responsible for the spreading pattern of a single paravertebral injection are still uncertain. In this study, 28 patients were randomly assigned to receive a paravertebral injection of radio-opaque dye (10 ml, with or without co-administration of 20 ml of local anaesthetics) either dorsal or ventral to the endothoracic fascia. ⋯ Injections made in the more ventral part of the thoracic paravertebral space, supposedly anterior to the endothoracic fascia, resulted in a multisegmental longitudinal spreading pattern, whereas injections made dorsal to the endothoracic fascia resulted in a less predictable cloud-like spreading pattern, with only limited distribution over adjacent segments. The use of a nerve stimulator-guided technique appears to enhance the likelihood of achieving the more desirable longitudinal spreading pattern.

Case ReportsThe use of cervical paravertebral block as the sole anesthetic for shoulder surgery in a morbid patient: a case report.
The purpose of this case report is to describe the use of the cervical paravertebral block as the sole anesthetic for shoulder surgery in a patient unable to tolerate general anesthesia. Recent literature describes the continuous cervical paravertebral block as an effective alternative to the interscalene block for the management of postoperative pain after shoulder surgery. ⋯ Continuous cervical paravertebral block provided excellent surgical conditions and postoperative pain relief for this patient and allowed gradual and intermittent dosing of the catheter and continuous assessment of the anesthetic impact on respiratory function.

Clinical evaluation of a modified posterior anatomical approach to performing the popliteal block.
Tibial and common peroneal nerves can be blocked by the posterior approach to the popliteal fossa. Techniques using fixed measured distances between knee skin crease and puncture point have been described. We report on an approach that is based on manual identification of the apex of the popliteal fossa. ⋯ The modified posterior anatomical approach for popliteal sciatic nerve block is easy to perform, has a high success rate, and has a low complication rate. The location of the needle insertion point is assessed without any measurement, thus avoiding inaccuracies caused by repeated skin-distance measurements.
