“…However, the complete block developed in these observations to the 30th minute. Related to previous eye surgeries, a report was published that the time for the development and blockade duration compared when retrobulbar block was performed with ropivacaine and using a mixture (1 : 1) of bupivacaine and lidocaine [4]. Chelly [5] wrote that, to achieve surgical anesthesia of the sciatic nerve, 15-20 min are required if ropivacaine 0.75% is used and 10-20 min if 0.75% ropivacaine is mixed with 1.5% lidocaine.…”

BackgroundThe purpose of the current study is to create a new mixture of local anesthetics-one with a short time of block development and short action term (5 ml of 1% lidocaine solution) and another with a longer time of anesthesia development and a long analgetic effect (5 ml of 0.75% ropivacaine)-for use during surgical operations on extremities. The primary end point was the development of the complete sensory block of the sciatic nerve.MethodsSixty blocks of sciatic nerve were used in a double-blind randomized research, under ultrasonic guidance, using an electric stimulator with the peripheral nerves. Sixty patients were divided into 3 equal groups. In the first group, a sciatic nerve block was performed with 5 ml of 0.75% ropivacaine solution (37.5 mg); in the second group, 10 ml of 0.75% ropivacaine solution (75 mg) was used and, in the third group, a mixture of 5 ml of 0.75% ropivacaine (as above) and 5 ml of 1% lidocaine solution (50 mg) was used. The assessment of the time required for developing sensory and motor blocks was carried out from the beginning of local anesthetic solution injection in the fascial sheath of the sciatic nerve.ResultsDemographic data of patients were identical in the three sample groups. The time required for achieving a complete motor and sensory block was reduced due to the mix of the 1% lidocaine solution with the 0.75% ropivacaine solution. The time required for achieving a complete sensory block in groups treated with 5 and 10 ml ropivacaine was 45 (40-48) and 30 (28-30) min, respectively, in contrast with 12 (10-13) min when the mixture of anesthetics was applied (P < 0.01). There was no difference in analgesic duration in the postoperative period among groups at P > 0.05.ConclusionsThe mixture of 5 ml of 1% lidocaine with 5 ml of 0.75% ropivacaine leads to a reduction in the time required for the development of complete sensory and motor blocks of the sciatic nerve, without reducing postoperative analgesia time.

BACKGROUNDMost of the surgeries within the orbit, particularly cataract surgeries are done under regional anaesthesia in day-care surgical centres. Proper selection of patients, thorough pre-operative evaluation and preparation, continuous monitoring during regional anaesthesia are necessary for safe outpatient surgery in the elderly.We compared the efficacy of peribulbar block in cataract surgery using the combination of 1:1 mixture of 2% lignocaine and 0.75% ropivacaine with 1:1 mixture of 2% lignocaine and 0.5% bupivacaine regarding the time required for onset of surgical anaesthesia and quality of postoperative analgesia.
