Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialRemifentanil versus alfentanil as analgesic adjuncts during placement of ophthalmologic nerve blocks.
Short-acting opioids are often used prior to the placement of ophthalmologic nerve blocks. This study examines whether remifentanil would provide superior analgesia compared with alfentanil, without oversedation or prolonged recovery when given either as a single dose over 30 seconds or as a single dose followed by a continuous infusion, in a dose ratio of 1:7 (remifentanil:alfentanil). ⋯ Remifentanil 1 microg/kg results in superior analgesia compared with alfentanil 7 microg/kg when used during the placement of ophthalmologic nerve blocks. The combination of a single dose of remifentanil followed by a continuous infusion was equally effective but resulted in a higher incidence of respiratory depression.

Randomized Controlled Trial Comparative Study Clinical TrialRopivacaine for peribulbar anesthesia.
We compared the efficacy of a mixture of ropivacaine and lidocaine with a mixture of bupivacaine and lidocaine for providing peribulbar anesthesia for cataract surgery. We used the time to adequate block for surgery and ocular and eyelid movement scores as clinical end points. ⋯ Ropivacaine 1% is an effective alternative to 0.75% bupivacaine for peribulbar anesthesia, when combined with lidocaine and hyaluronidase.

Randomized Controlled Trial Clinical TrialRetrobulbar/peribulbar block with 0.2% ropivacaine or 1% lidocaine for transscleral cyclophotocoagulation or retinal panphotocoagulation.
Brief analgesia is needed to complete krypton laser cyclophotocoagulation for glaucoma patients and is advantageous in argon laser panphotocoagulation for diabetic retinopathy. We studied whether 0.2% ropivacaine, known for analgesia with minimal motor block or 1% lidocaine, with rapid onset and short duration of action, both supplemented with hyaluronidase, are suitable local anesthetics for retrobulbar/peribulbar block for these procedures. ⋯ According to our preliminary data, neither 0.2% ropivacaine nor 1% lidocaine reached acceptable frequencies of adequate analgesia during transscleral cyclophotocoagulation, while all retinal panphotocoagulations could be completed under the initial block.

Anesthesiologists are increasingly utilizing the Internet for personal and professional purposes. Without guidance, the task of searching the Internet for information may be time-consuming and frustrating. This article includes a basic introduction to the Internet with suggestions and guidelines for accessing information resources. Future articles will address locating articles about human anatomy, regional anesthesia and pain medicine. ⋯ This is the first in an informal series of articles demonstrating and describing information technology. The articles will include nontechnical information and will detail the experiences and wisdom obtained from experienced anesthesiologists. The series is geared toward the computer novice with interest in regional anesthesia and pain medicine. These articles are also available in full text on the American Society of Regional Anesthesia website (www.asra.com) with links to the websites in the article.
