BACKGROUND Ropivacaine provides effective spinal anaesthesia for total hip arthroplasty. This study was designed to compare the efficacy and safety of plain ropivacaine with plain bupivacaine for spinal anaesthesia in patients undergoing total hip arthroplasty. METHODS Sixty-six patients, ASA I or II, were randomized to receive an intrathecal injection of one of two local anaesthetic solution...

BACKGROUND Intrathecal α2 agonists prolong the duration of action of local anesthetics and reduce the required dose. Dexmedetomidine is an α2 receptor agonist and its α2/α1 selectivity is 8 times higher than that of clonidine. AIMS In this study, we aimed to investigate the effect of adding dexmedetomidine to intrathecal levobupivacaine on the onset time and duration of motor and sensory bloc...

BACKGROUND AND AIMS A popliteal block is effective in managing postoperative pain for foot surgery, but since the duration of analgesia is limited following a single-shot popliteal fossa block technique, methods to prolong effective postoperative analgesia are mandatory. The aim of this study was to assess the effect of adjuvants to ropivacaine on the duration of sensory and motor block. METH...

BACKGROUND Anesthesia induction in patients with current substance abuse can be a challenge for anesthesiologists. OBJECTIVES This study aimed to evaluate the effect of adding Sufentanil to Bupivacaine on duration of brachial plexus nerve block. PATIENTS AND METHODS One hundred and twenty patients with (Groups C and D) and without (Groups A and B) a history of opium abuse (60 in each group)...

OBJECTIVE To determine whether the addition of 8 mg dexamethasone to axillary brachial plexus block would prolong the duration of sensory and motor block in patients undergoing hand and forearm surgery. METHODS The prospective, randomised, double-blinded study was conducted at the Eskisehir Osmangazi University Medical School, Turkey, from October 2008 to December 2009. It comprised 45 Americ...

BACKGROUND The analgesic effect of a TAP block has been investigated in various surgical settings. There are however limited information about block level and block duration. Furthermore, there is a lack of information about continuous TAP block after ultrasound-guided posterior TAP blocks.The aim of this double-blind randomized study was therefore to investigate the effect of an ultrasound-gui...

abstract background: different adjuvant drugs have been used with local anesthetics in order to decrease the time of onset and elongate the duration and quality of regional blocks. this study was performed to study the effects of one of the adjuvants, verapamil, in supraclavicular block. methods: in this double blinded clinical trial, we divided 60 asa class i and ii patients who were to underg...

Introduction Spinal anesthesia is a widely used technique providing faster onset with effective and uniformly distributed sensory and motor block. Due to decreased cardiovascular and central nervous system toxicity, levobupivacaine is a good alternative for spinal anesthesia. Dexmedetomidine when used intrathecally is associated with prolonged motor and sensory block, hemodynamic stability, and...

BACKGROUND The authors compared the efficacy of the different approaches to saphenous nerve block. METHODS The following approaches to saphenous nerve block were compared in 10 volunteers: perifemoral, transsartorial, block at the medial femoral condyle, below-the-knee field block, and blockade at the level of the medial malleolus. Each volunteer underwent all five blocks, and the interval be...
