Anesthesiologists have become increasingly involved with the management of chronic pain patients in the operating room, on the surgical floor, and in the outpatient pain facility setting (often interdisciplinary). Based upon the authors' practice of regional anesthesia, the most specific contribution to chronic pain management arguably remains the practice of diagnostic, prognostic, and therapeutic injections of the neuraxis, peripheral nerves, and the autonomic nervous system.

Randomized Controlled Trial Clinical TrialHaemodynamic effects of subarachnoid blockade: 20% lignocaine versus 0.5% plain bupivacaine.
Our study compared the haemodynamic changes after spinal anaesthesia with 2% lignocaine and 0.5% plain bupivacaine. ⋯ In patients developing a sensory block at or above the T6 dermatome, the decrease in cardiac output and mean arterial pressure in the first 25 min. after spinal anaesthesia is smaller if 2% lignocaine rather than 0.5% bupivacaine is used for blockade.

Comparative StudyCombined sciatic-paravertebral nerve block vs. general anaesthesia for fractured hip of the elderly.
Sixty elderly patients scheduled for surgical hip fracture repair were given the choice of either general isoflurane anaesthesia (n = 30) or a nerve stimulator guided combined sciatic-paravertebral nerve block (n = 30). The incidence of intraoperative hypotension and the need for postoperative admission to the intensive care unit/high dependency unit (ICU/HDU) within 48 hours postoperatively were recorded. ⋯ The length of hospital stay was also found to be shorter for patient in the regional anaesthesia group [mean 6.7 days (SD 2.3) vs. 13.6 days (SD 6.1)]. The described technique appears to be an attractive alternative method to handle proximal fractures of the femur in the elderly, especially in a situation with limited ICU/HDU availability.

To evaluate the effects of unilateral stellate ganglion blockade on left ventricular function. ⋯ In patients without cardiovascular disease, unilateral denervation of the left ventricle after stellate ganglion block produces no clinical deleterious effects on left ventricular function.
