Describe early discharge of patients treated with continuous perineural analgesia after orthopaedic surgery. ⋯ Continuous, post-operative, perineural analgesia at home is safe and effective, less expensive with high patient satisfaction.

The incidence of pneumothorax (PTX) after individual intercostal nerve block (INB) for postoperative pain reportedly varies from 0.073% to 19%.1-3 This study investigated the incidence of PTX after INB for rib fractures. ⋯ The incidence of PTX per individual intercostal nerve blocked is low. INB is an effective form of analgesia, and for most patients with rib fractures one INBP is sufficient to allow adequate respiratory exercises and discharge from the hospital.

Clinical significance of the length of the pterygopalatine fissure in dental anesthesia.
This study determined the average length of the pterygopalatine fissure by using human cadavers. Recommendations are made to improve the success of maxillary nerve block injections. ⋯ Depth of penetration with a needle that is longer than that normally available is necessary to predictably ensure a successful maxillary nerve block.

High concentrations of adrenergic antagonists prolong sciatic nerve blockade by tetrodotoxin.
Millimolar-range concentrations of some adrenergic antagonists have been shown to have local anesthetic-like properties, and to stimulate GTPase activity in vitro. In this report, we investigate whether these agents can potentiate the effect of tetrodotoxin (TTX) and bupivacaine, a conventional local anesthetic, and whether GTPase activation plays a role. ⋯ High concentrations of adrenergic antagonists markedly prolonged TTX block, but not bupivacaine block. This locally mediated action does not appear to be adrenergic-receptor-specific, or mediated by GTPase activation.
