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...

Background: Alpha-2 agonists are added to local anesthetic agents to extend the duration of peripheral nerve blocks. Objective: We evaluated the effect of combining dexmedetomidine with levobupivacine with respect to duration of motor and sensory block and duration of analgesia. Material and Methods: Sixty patients of ASA grade I or II aged between 18-60 years, posted for elective upper limb su...

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...

INTRODUCTION The present study compared the effect of bupivacaine and bupivacaine + sufentanil on hemodynamic parameters and characteristics of spinal anesthesia in elderly patients undergoing transurethral resection of the prostate (TURP) under spinal anesthesia. TECHNICAL CONSIDERATIONS The study included 40 American Society of Anesthesiologists (ASA) I-III patients scheduled to undergo TUR...

OBJECTIVE In the current prospective, randomized study, we aimed to compare the effects of low dose selective spinal anesthesia with 5 mg of hyperbaric bupivacaine and single-shot femoral nerve block combination with conventional dose selective spinal anesthesia in terms of intraoperative anesthesia characteristics, block recovery characteristics, and postoperative analgesic consumption. PATI...

OBJECTIVES The aim of this study was to investigate whether tramadol had a dose-dependent blocking effect on nerve conduction when administered perineurally to the sural nerve of healthy volunteers. METHODS Twenty-four informed healthy subjects were randomized into four equal groups [Saline (placebo), 0.5% tramadol, 1% tramadol and 1.5% tramadol]. The study was designed to be double-blinded. ...

BACKGROUND AND OBJECTIVE The recommendations for the level of injection and ideal placement of the needle tip required for successful ultrasound-guided sciatic popliteal block vary among authors. A hypothesis was made that, when the local anesthetic is injected at the division of the sciatic nerve within the common connective tissue sheath, the block has a higher success rate than an injection ...

BACKGROUND The objective ofthe present study was double fold; to compare the characteristics of spinal blocks produced by 0.5% levobupivacaine with and without fentanyl in transurethral resection and to test the hypothesis that, fentanyl added to levobupivacaine, may be used as an alternative to pure levobupivacaine solution, in spinal anesthesia. METHODS Forty males, aged >60 years, ASA I-II...

Aims and Objectives: The aim of this study is to evaluate the effects of Dexmedetomidine and Fentanyl as intrathecal adjuvant to Bupivacaine on the onset and duration of sensory and motor block in spinal anaesthesiain orthopaedic lower limb and lower abdominal surgeries. Materials and Method: Ninety patients of ASA status I and II posted for lower limb and lower abdominal surgery were randomly ...

BACKGROUND AND AIM Dexmedetomidine (D) is a α2 agonist, has anesthetic and analgesic-sparing property. The objective of this study was to evaluate the effect of intravenous (I.V.) dexmedetomidine on the duration of sensory and motor block, postoperative analgesia, the level of sedation and side effect. MATERIAL AND METHODS Sixty patients were randomly divided into two groups of thirty each. G...
