Randomized Controlled Trial Comparative Study Clinical TrialThe use of ultrasound for guiding needle placement for inferior alveolar nerve blocks.
The degree of pulpal anesthesia obtained with an ultrasound-assisted inferior alveolar nerve block was compared to that obtained with a conventional inferior alveolar nerve block for mandibular teeth to determine whether needle placement assisted by ultrasound results in more successful anesthesia. ⋯ It was concluded that accurate needle placement with ultrasound for the inferior alveolar nerve block did not result in more successful pulpal anesthesia in the mandible. Therefore, accuracy of needle placement is not the primary reason for pulpal anesthetic failure with this block.

Randomized Controlled Trial Comparative Study Clinical Trial
[Pain therapy after thoracoscopic interventions. Do regional analgesia techniques (intercostal block or interpleural analgesia) have advantages over intravenous patient-controlled opioid analgesia (PCA)?].
Systemic opioids and thoracic epidural analgesia are common techniques used to provide post-operative analgesia following thoracoscopy (video-assisted thoracic surgery). The aim of the present prospective randomised study was to evaluate the efficacy of two less invasive analgesic techniques, intercostal blocks (ICB) and interpleural analgesia (IPA). After approval from the ethics committee and informed consent from the patients, 36 patients scheduled for thoracoscopic surgery were randomly assigned to a group for postoperative pain management: group ICB: intercostal blocks of the segments involved with 5 ml 0.5% bupivacaine at the end of surgery and 6 h later; group IPA: interpleural analgesia with 20 ml 0.25% bupivacaine applied every 4 h using a catheter placed during surgery near the apex of the interpleural space; control group: IV-opiod-PCA with piritamide. ⋯ Nevertheless, effective pain management is necessary. We could not demonstrate a significant reduction in piritramide consumption for the techniques of regional analgesia tested here (ICB, IPA). We conclude that the use of these techniques is not complementary after thoracoscopy, since an opioid (PCA with piritramide) combined with a non-opioid (metamizol) resulted in satisfactory analgesia.

Comparative Study
A collaborative regional ocular anesthesia training program: successes and failures.
To describe a collaborative effort of the departments of ophthalmology and anesthesiology to teach anesthesiology residents regional ocular anesthesia; to detect any differences in positive or negative outcomes after blocks performed by anesthesiology residents versus blocks performed by ophthalmology residents. ⋯ Regional ocular anesthetic techniques can be safely and successfully taught to residents in anesthesiology.
