Randomized Controlled Trial Comparative StudyEffects of the addition of subarachnoid clonidine to the anesthetic solution of sufentanil and hyperbaric or hypobaric bupivacaine for labor analgesia.
The addition of subarachnoid clonidine (alpha-agonist) prolongs the analgesia produced by the combination of sufentanil and isobaric bupivacaine in combined labor analgesia(1). The objective of this study was to compare the quality of analgesia and the prevalence of side effects after the addition of subarachnoid clonidine to the anesthetic solution in labor analgesia. ⋯ Under the conditions of the present study, the association of a small dose of clonidine (30 microg) with sufentanil caused a higher incidence of hypotension when the isobaric solution of the local anesthetic was used. For all other side effects, both hyperbaric and isobaric solutions showed similar behavior.

Randomized Controlled Trial Comparative StudyA comparative study between 25 x 0.70 mm and 20 x 0.55 mm needles for retrobulbar block with small volume of anesthetic for the treatment of cataracts by phacoemulsification.
The objective of this study was to compare the quality and safety of retrobulbar block for the treatment of cataracts by phacoemulsification using needles of different sizes: 27 x 0.70 mm and 20 x 0.55 mm. ⋯ Retrobulbar block with a single inferolateral puncture with a 20 x 0.55 mm needle, using low doses of anesthetics, is an effective and safe option for the treatment of cataracts by phacoemulsification.
