The sensory block levels of 102 women undergoing caesarean section under spinal anaesthesia were assessed by four different methods: sharp pinprick (Neurotip tester pin), cold (ethyl chloride spray), touch (Neurotip tester pin), touch (ethyl chloride spray). While the data indicate a median difference of some 2 segments between the levels of block assessed by sharp pinprick or cold, and touch, ...

Although supraclavicular brachial plexus block (SCBPB) was repopularized by the introduction of ultrasound, its usefulness in shoulder surgery has not been widely reported. The objective of this study was to compare motor and sensory blockades, the incidence of side effects, and intraoperative opioid analgesic requirements between SCBPB and interscalene brachial plexus block (ISBPB) in patients...

Introduction: Different types of additives are commonly used to prolong the duration of brachial plexus block.The present study was aimed to test the hypothesis that dexmedetomidine produces a superior analgesia, motor block and post operative analgesia when added as an adjuvant to ropivacaine 0.5% in supraclavicular brachial plexus block. Materials andMethods: A total of 100 patients (20-50 ye...

we present a case of unexpectedly prolonged motor and sensory block following a successful single injection ultrasound – guided infraclavicular block with bupivacaine (0.25%) and dexamethasone (8 mg). ultrasound guidance and safety measurement such as injection of the local anaesthetic at a slow rate and verifying that usual resistance was felt throughout the injection, has been applied. it too...

BACKGROUND AND AIMS The primary aim of this study was to evaluate the effect of addition of dexmedetomidine on the duration of analgesia in patients undergoing upper limb surgeries under supraclavicular brachial plexus block. MATERIAL AND METHODS Sixty patients of American Society of Anesthesiologists physical status I/II/III undergoing elective upper limb surgeries under supraclavicular brac...

durbin's rank test is widely used for testing treatment effects in balanced incomplete block designs (bibds)which have wide applications in sensory analysis. this test is failed for bibds when ties data occur. an adjusted version of durbin rank test for this kind of data is given to solve this problem. chi-square approximation, which is commonly used for this test, is not adequate for small bib...

BACKGROUND Our aim is to compare the hemodynamic effects of combined psoas compartment-sciatic nerve block (PCSNB) with continuous spinal anaesthesia (CSA) in elderly high-risk patients undergoing hip replacement surgery. METHODS Seventy patients over the age of 60 with ASA III or IV physical status were randomly allocated to two groups: In the PCSNB group, ultrasound-guided psoas compartment...

BACKGROUND Although lidocaine is a cheap and globally available local anesthetic, yet it is not a popular drug for labor analgesia. This is claimed to its higher intensity of motor block, possibility of transient neurological symptoms (TNS) and its placental transfer with probable drawbacks on fetal well-being. However, these effects could be concentration dependent and, the evidence linking th...

OBJECTIVE In this study, we compared the clinical effects of combined doses of ropivacaine and clonidine. MATERIALS AND METHODS Seventy-five patients between ages 18 and 75, in ASA I-III groups who were to undergo elective lower extremity surgery, were included in the study with informed consent. Subjects were randomly assigned to 3 groups. Group I: % 1 ropivacaine 12 mg, group II: % 1 ropiva...
