Randomized Controlled TrialAnesthetic efficacy of buccal and lingual infiltrations of lidocaine following an inferior alveolar nerve block in mandibular posterior teeth.
The authors, using a crossover design, randomly administered, in a single-blind manner, 3 sets of injections: an inferior alveolar nerve block (IANB) plus a mock buccal and a mock lingual infiltration of the mandibular first molar, an IANB plus a buccal infiltration and a mock lingual infiltration of the mandibular first molar, and an IANB plus a mock buccal infiltration and a lingual infiltration of the mandibular first molar in 3 separate appointments spaced at least 1 week apart. An electric pulp tester was used to test for anesthesia of the premolars and molars in 3-minute cycles for 60 minutes. Anesthesia was considered successful when 2 consecutive 80 readings were obtained within 15 minutes following completion of the injection sets, and the 80 reading was continuously sustained for 60 minutes. ⋯ For the IANB plus mock buccal infiltration and lingual infiltration, successful pulpal anesthesia ranged from 54 to 76% from the second molar to second premolar. There was no significant difference (P > .05) in anesthetic success between the IANB plus buccal or lingual infiltrations and the IANB plus mock buccal infiltration and mock lingual infiltration. We conclude that adding a buccal or lingual infiltration of 1.8 mL of 2% lidocaine with 1:100,000 epinephrine to an IANB did not significantly increase anesthetic success in mandibular posterior teeth.

Randomized Controlled Trial Comparative StudyThe analgesic efficacy of two different approaches to the lumbar plexus for patient-controlled analgesia after total knee replacement.
This study assessed the efficacy of a patient-controlled regional analgesia technique for either psoas compartment block or femoral nerve block after total knee replacement in 68 patients who were randomly divided into these two groups. All patients received 40 ml of 0.25% bupivacaine via femoral or psoas catheters before general anesthesia, and then, as patient-controlled regional analgesia, 10-ml boluses of 0.125% bupivacaine, with a lockout time of 60 min over 48 h. ⋯ All measured parameters were comparable in the two groups. Both techniques achieved a good quality of analgesia and satisfaction without any major side effect.

Randomized Controlled Trial Comparative StudyOne-day surgery for acquired forefoot deformity: sciatic nerve blockade with mepivacaine vs mepivacaine+ropivacaine: a prospective, randomized study.
The aim of the study was to determine the doses of ropivacaine combined with mepivacaine for sciatic nerve blockade to enable the extension of analgesia without prolonged motor blockade, for the management of very painful operations in one-day surgery. ⋯ Adequate doses of ropivacaine added to mepivacaine for peripheral blockade produce and increase the duration of analgesia without influencing the criteria for discharge after Day Surgery.

Randomized Controlled Trial Comparative StudyComparison between spinal anaesthesia and sciatic-femoral block for arthroscopic knee surgery.
We compared spinal anesthesia and sciatic-femoral block for arthroscopic knee surgery in terms of hemodynamic changes, intraoperative anesthesia, postoperative analgesia, postoperative motor block and bladder function, side effects, and patient satisfaction. ⋯ In conclusion the sciatic-femoral nerve block is a valid alternative to spinal anesthesia for arthroscopic knee surgery, leading to a faster discharging from the hospital.
