Comparison of neural blockade and pharmacokinetics after subarachnoid lidocaine in the rhesus monkey. II: Effects of volume, osmolality, and baricity.
The effects of volume, osmolality, and baricity on lidocaine spinal anesthesia in the rhesus monkey were studied. Changes in neural blockade, physical properties of cerebrospinal fluid, and arterial pharmacokinetics associated with variations in injectate composition were assessed. Wide ranges of volume, baricity, and osmolality were studied using 1, 2, and 5% lidocaine prepared in either sterile water or 7.5% dextrose. ⋯ No differences in elimination phase pharmacokinetics were found with any of the lidocaine solutions. Rates of systemic absorption increased with decreasing osmolality. Osmotic potentiation of lidocaine spinal anesthesia could not be demonstrated.

Comparative Study
Forum. Femoral neck surgery using a local anaesthetic technique.
Thirty cases of femoral sub-capital fractures, Garden grades 1-4, were reduced and internally fixed with crossed Garden screws using femoral nerve block. In addition, sedation and analgesia was provided by low dose ketamine and diazepam. No deaths or other complications occurred in these patients. In a similar group of patients who received spinal analgesia in the same unit under similar conditions there was one death and two cerebrovascular accidents.

Case ReportsComplications of intercostal nerve blocks performed under direct vision during thoracotomy: a report of two cases.
Intrathoracic intercostal nerve block is a well-described procedure used to provide postoperative pain relief following thoracotomy. The two cases described present possible complications secondary to such blocks and suggest that the routine use of intrathoracic intercostal nerve blocks should be discouraged.
