Randomized Controlled Trial Comparative Study Clinical TrialA comparison of articaine and lidocaine for inferior alveolar nerve blocks.
The purpose of this prospective, randomized, double-blind study was to compare the degree of pulpal anesthesia obtained with 4% articaine with 1:100,000 epinephrine and 2% lidocaine with 1:100,000 epinephrine in inferior alveolar nerve blocks. Using a crossover design, inferior alveolar nerve blocks were randomly administered, in a double-blind manner, using 4% articaine with 1:100,000 epinephrine and 2% lidocaine with 1:100,000 epinephrine, at two separate appointments, to 57 subjects. A pulp tester was used to test for anesthesia, in 4-min cycles for 60 min, of the molars, premolars, central, and lateral incisors. ⋯ Using the lidocaine solution, successful pulpal anesthesia ranged from 2 to 48%. There was no significant difference (p > 0.05) between the articaine and lidocaine solutions. We concluded that 4% articaine with 1:100,000 epinephrine was similar to 2% lidocaine with 1:100,000 epinephrine in inferior alveolar nerve blocks.

Randomized Controlled Trial Clinical TrialClonidine as an adjuvant for lidocaine in axillary brachial plexus block in patients with chronic renal failure.
Clonidine is often used as an adjuvant for local anaesthetics in regional anaesthesia; however, its effects on axillary block in chronic renal failure patients have not been investigated. These effects were the focus of this study. ⋯ Use of clonidine (150 microg) as adjuvant for lidocaine in axillary blocks for arteriovenous fistula construction in chronic renal failure patients prolongs blockade, decreases both heart rates and blood pressures and provides sedative effects.

Case ReportsLateral cervical epidural catheter placement using nerve stimulation for continuous unilateral upper extremity analgesia following a failed continuous peripheral nerve block.
This case report describes the application of electrical stimulation (Tsui test) to confirm placement of a cervical epidural catheter for postoperative pain management in a patient with a failed brachial plexus block who underwent upper extremity surgery. An epidural catheter was easily advanced under nerve stimulation guidance to the surgical dermatome C4 level without any resistance from the C7-T1 level. ⋯ This case reminds the clinician that cervical epidural analgesia may serve as an alternative to a difficult continuous peripheral nerve block. Electrical stimulation may also help to confirm cervical epidural catheter placement at the appropriate dermatome to provide effective analgesia with minimal side-effects.

Combined ilioinguinal blockade and local infiltration anaesthesia for groin hernia repair--a double-blind randomized study.
Local infiltration anaesthesia for inguinal hernia repair is cost-effective, but fear of intra-operative pain may hinder its widespread use. It is unknown whether a combined ilioinguinal blockade and local infiltration anaesthesia improves intra-operative analgesia. ⋯ Combined ilioinguinal blockade and local infiltration anaesthesia is recommended for groin hernia repair to reduce intra-operative pain.
