Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Haematoma block or Bier's block for Colles' fracture reduction in the accident and emergency department--which is best?
To offer clear guidance on the anaesthetic management of Colles' fractures in the accident and emergency (A&E) department in the light of the conflict between existing reports and current trends, and to address the issue of alkalinisation of haematoma blocks. ⋯ Bier's block is superior to haematoma block in terms of efficacy, radiological result, and remanipulation rate; transit times are equal, both procedures are practical in the A&E environment, and there were no complications. Bier's block is the anaesthetic management of choice for Colles' fractures requiring manipulation within the A&E department.

Clinical TrialFailed axillary brachial plexus block techniques result in high plasma concentrations of mepivacaine.
Unintentional extrasheath injection causes failed axillary brachial plexus block. We wanted to find out if extrasheath injections produce higher plasma concentrations of local anesthetics compared to intrasheath injections. We also studied the incidence of extrasheath injection with radiographs. ⋯ Failed extrasheath injection of 50 mL 1.5% plain mepivacaine produces higher arterial plasma concentration in axillary brachial plexus block.

Randomized Controlled Trial Clinical Trial
Effectiveness of bupivacaine administered via femoral nerve catheter for pain control after anterior cruciate ligament repair.
To evaluate the quality of pain control achieved with continuous local anesthetic infusion via a femoral nerve catheter, and to determine the optimum concentration of bupivacaine necessary to maintain pain control after full surgical anesthesia is established with 0.5% bupivacaine. ⋯ Low concentrations of bupivacaine delivered via femoral nerve catheter after an established femoral nerve block can provide excellent postoperative pain control after ACL reconstruction.

Comparison of caudal block using bupivacaine and ketamine with ilioinguinal nerve block for orchidopexy in children.
Forty boys weighing less than 25 kg undergoing unilateral orchidopexy were randomly allocated to receive one of two analgesic regimens. Group C received a caudal epidural block with 0.25% bupivacaine 1 ml.kg-1 and preservative-free ketamine 0.5 mg.kg-1; Group L received an ilioinguinal nerve block with 0.25% bupivacaine 0.5 ml.kg-1 and infiltration of the wound with 0.25% bupivacaine 0.5 ml.kg-1. All subjects received diclofenac sodium 1-2 mg.kg-1 as a rectal suppository. ⋯ The median duration of analgesia was 10 h (range 2.6 to > 24 h) in Group C and 2.9 h (range 0.7 to > 24 h) in Group L (p < 0.05). There were no differences between groups in the incidence of motor block, urinary retention, postoperative vomiting or postoperative sedation. Subjects in Group L required significantly more doses of postoperative analgesia than those in Group C (p < 0.05).

The duration of action of bupivacaine, levobupivacaine, ropivacaine and pethidine in peripheral nerve block in the rat.
There is a current interest in local anaesthetic drugs/formulations exhibiting long durations of sensory block and minor motor-blocking effects. ⋯ Equimolar doses of the investigated local anaesthetics exerted similar durations of sensory blockade in a peripheral nerve block model in the rat.
