Background and aims: Hyperbaric prilocaine is a short-acting local anaesthetic. The aim of this study is to compare the characteristics of subarachnoid block using hyperbaric prilocaine with that of bupivacaine in outpatients undergoing transurethral resection of bladder (T.U.R.B.). Methods: In this prospective randomized controlled trial, 60 patients undergoing endoscopic urological surgery re...

Purpose To compare the effects of dexmedetomidine (Dex) and fentanyl as adjuvants to local anesthetics in spinal anesthesia. Methods Two researchers independently searched the PUBMED, EMBASE, Cochrane library, and CBM for randomized controlled trials comparing the effects of Dex and fentanyl as adjuvants to local anesthetics for intrathecal injection. Results A total of 639 patients from ni...

To evaluate the hypothesis that adding dexmedetomidine to ropivacaine prolongs axillary brachial plexus block. Forty-five patients of ASA I~II and aged 25-60 yr who were scheduled for elective forearm and hand surgery were randomly divided into 3 equal groups and received 40 ml of 0.33% ropivacaine + 1 ml dexmedetomidine (50 μg) (Group DR1), 40 ml of 0.33% ropivacaine + 1 ml dexmedetomidine (10...

Background: Many researchers have been done to find an ideal adjuvant to ropivacaine in regional anaesthesia that inhibits intra and post-operative pain and prolong the duration of anaesthesia without any side effects. Aim: This study was conducted to evaluate the onset, extent and duration of sensory and motor block and side effects of clonidine or dexmedetomidine when used as an adjuvant to r...

BACKGROUND The purpose of the present study is to investigate the anesthetic effect of reduced doses of spinal bupivacaine with epidural top ups in comparison with those of spinal bupivacaine and to determine the adequate doses of drugs used during lower extremity surgeries. METHODS SIXTY ADULT PATIENTS WERE RANDOMIZED TO THREE DIFFERENT TECHNIQUE GROUPS: S group (10 mg of spinal bupivacaine)...

BACKGROUND Sensory assessment to estimate spread and effectiveness of a peripheral nerve block is difficult because no clinical test is specific for small sensory fibers. Occurrence of a swelling illusion (SI) during a peripheral nerve block corresponds to the impairment of small sensory fibers. The authors investigated the usefulness of SI in predicting successful peripheral nerve block by ass...

the quality of subarachnoid block can be improved by adding opioids to the local anesthetics. we compared the analgesic effects of different doses of intrathecal sufentanil added to lidocaine %5 for elective cesarean section. this study was a prospective, randomized, double-blind, controlled trial. 90 pregnant women with asa class i-ii, scheduled for elective cesarean section under spinal anest...

BACKGROUND The present preliminary study documents the effects of a selective nerve root block (SNB) with short or long acting local anaesthetic compared with baseline measurements in patients with chronic low back pain radiating to the leg with maximum pain in one dermatome (L4). METHODS Ten consecutive patients underwent 20 controlled SNBs at L4 with ropivacaine 0.25% and lidocaine 1% in a ...
