OBJECTIVE To quantitatively evaluate the effect of motor nerve branch block and neurotomy of the soleus nerve on triceps surae spasticity, reviewing 2 cases. METHODS Beside clinical assessment, we carried out a quantitative measurement of the stiffness of the ankle flexor muscles. The path length of the phase diagram between elastic and viscous stiffness quantifies the reflex response to move...

Many techniques and drug regimens, with partial or greater success, have been tried from time to time to eliminate the anxiety component and to prolong the postoperative analgesia during regional anesthesia. α 2 agonists like clonidine, dexmedetomidine are used as adjuvant to local anaesthetics in order to prolong the duration of spinal anaesthesia. They potentiate the effect of local anestheti...

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...

The aim of the present study was to compare the amount of motor block produced by different loading doses of ropivacaine and bupivacaine when delivered in a dilute solution with added opioid. Sixty-eight healthy term primigravid parturients were randomized to receive an initial bolus dose of 10 mL of 1 of the following: 0.25% bupivacaine (high bupivacaine), 0.25% ropivacaine (high ropivacaine),...

OBJECTIVE The aim of this study is to compare the effects of parasacral and posterior Winnie approaches when combined with the inguinal paravascular approach for lumbar plexus block. METHODS After the approval of the Ethics Committee, 40 patients scheduled to undergo arthroscopic knee surgery were enrolled. The patients were randomly assigned into two groups in a double-blind manner to perfor...

BACKGROUND Conduction block is considered an essential finding for the distinction between motor neuropathies and lower motor neuron disorders. Only a small number of reports describe patients with multifocal motor neuropathies who lack overt conduction block, although in these cases other features of demyelination still suggest the presence of a demyelinating disorder. In contrast, a purely ax...

OBJECTIVE We aimed to compare lateral and midline epidural anaesthesia using a levobupivacaine-fentanyl combination in patients undergoing unilateral lower extremity operation for anaesthetic effects and postoperative complications. METHODS The study included 40 American Society of Anesthesiologists (ASA) I-II group patients. At the L4-5 space, an epidural catheter was placed in patients in G...

Objectives: This randomized double-blind controlled trial examined the effects of fentanyl and morphine, alone and in combination, as adjuncts to spinal anesthesia for elective cesarean section. Methods: Sixty women undergoing elective cesarean section, with spinal anesthesia using 0.5% hyperbaric bupivacaine, were randomly allocated to receive morphine 0.2 mg, fentanyl 25 μg, or fentanyl 12.5 ...

Objective: This study was designed to compare the effects of equivalent doses of bupivacaine and levobupivacaine on propofol requirement in BIS guided sedation under spinal anesthesia. Material and Methods: Spinal anesthesia was performed on seventy patients scheduled for elective lower limb surgery with 3 mL’s of either isobaric bupivacaine (Group B) or plain levobupivacaine (Group L). Five mi...

BACKGROUND Coracoid approach is efficient and safe for brachial plexus block, and is guided by nerve stimulator or ultrasound in general. Many trials have proved that ultrasonic guidance was more efficacious than nerve stimulator guidance. We hypothesized that positioning posterior cord could enhance the anesthesia effect of coracoid approach brachial plexus block (CABPB) guided by nerve stimul...
