Randomized Controlled Trial Comparative Study Clinical TrialUltrasonographic guidance reduces the amount of local anesthetic for 3-in-1 blocks.
Recently it has been demonstrated that the use of ultrasound (US) improves the onset time and the quality of sensory block for 3-in-1 blocks compared with conventional nerve stimulator (NS) techniques. The present study was designed to evaluate if US guidance for 3-in-1 blocks reduces the amount of local anesthetic compared to NS guidance. ⋯ The amount of local anesthetic for 3-in-1 blocks can be reduced by using US guidance compared with the conventional NS-guided technique.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative analgesia in children using preemptive retrobulbar block and local anesthetic infiltration in strabismus surgery.
Postoperative pain management in pediatric strabismus patients is infrequently studied. Pediatric patients can be mobilized earlier if postoperative pain is minimized. In this study, two different regional anesthetic techniques, retrobulbar block and local infiltration, were compared with a "no block" control group for the postoperative management of pain in pediatric patients undergoing elective strabismus surgery. ⋯ Because there was no significant difference in terms of postoperative analgesia in the retrobulbar block or subconjunctival local anesthetic infiltration groups compared with the control group, we suggest that conventional methods of pain treatment are adequate for postoperative analgesia in strabismus surgery.

ReviewCommentary: neurotoxicity of local anesthetics--an issue or a scapegoat?
To evaluate the etiologies of cauda equina syndrome (CES) and transient radicular irritation (TRI) or transient neurologic symptoms (TNSs) following hyperbaric spinal anesthesia. ⋯ Cauda equina syndrome is, in all probability, explainable. Further investigation to pinpoint the etiology of TRI (TNSs) is needed.
