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.

Case ReportsConvulsions during superior laryngeal nerve block--a case report.
Complications following local anesthesia for fiberoscope-assisted intubation are rare. We report a case with surgical condition indicating awake endotracheal intubation for general anesthesia, suffering from convulsions after receiving left superior laryngeal nerve block to facilitate the procedure. The possible cause may be accidental injection of the local anesthetic into the vertebral artery. ⋯ The central nervous system toxicity of local anesthetic depends not only on the dosage used, but also on the rate of injection, as well as the site at which it is injected. Starting from a small dose together with careful monitoring of patient's response is advised when nerve block in the neck is performed. Here, we also emphasize the importance of availability of resuscitation equipment for maintaining adequate ventilation and circulation in case of emergency.
