Randomized Controlled Trial Comparative Study Clinical TrialBrachial plexus anaesthesia in children: lateral infraclavicular vs axillary approach.
Brachial plexus blockade is a well-established technique in upper-limb surgery. In paediatric patients, the axillary route is usually preferred to infraclavicular approaches because of safety considerations. Recent reports on a lateral infraclavicular approach offering greater safety in adults prompted us to perform a prospective randomized study to assess the analgesic efficacy of axillary vs lateral vertical infraclavicular brachial plexus (LVIBP) blocks in paediatric trauma surgery. ⋯ We conclude that LVIBP blocks can be safely performed in children and that they add to the spectrum of sensory and motor blockade seen with the axillary approach.

Randomized Controlled Trial Clinical Trial
Block of the sacral segments in lumbar epidural anaesthesia.
Block of the first sacral segment is often delayed in lumbar epidural anaesthesia. The addition of either epinephrine or sodium bicarbonate to the local anaesthetic enhances the efficacy of epidural block. We assessed the block of lumbo-sacral segments in lumbar epidural anaesthesia adding epinephrine and/or bicarbonate to lidocaine. ⋯ A combination of lidocaine, bicarbonate, and epinephrine increases the pain threshold over the sacral segments.

Randomized Controlled Trial Comparative Study Clinical Trial
Double-blind randomized comparison of xylocaine and saline in paracervical block for diagnostic fractional curettage.
Comparative study of the level of the reported pain between patients who received xylocaine and normal saline for paracervical block during fractional curettage was carried out in 70 patients in a double blind randomized controlled trial. One group of patients received xylocaine for paracervical block just before the procedure was performed while the other group received normal saline in the same manner. Self-reported pain intensity using visual analog scale was assessed at four time points including the first time point when Allis tissue forceps was applied on the cervix, the second and third time points when curettage was done on the endocervix and in the endometrial cavity respectively. ⋯ The explanation for this was the local anesthetic mechanism may be from distension of nerve capsules rather than blockage of specific autonomic nerves. However, this study showed that nerve capsule distension is not the only factor for pain control in paracervical block. An analgesic agent is still an important factor.

Randomized Controlled Trial Clinical Trial
Three-in-one femoral nerve block as analgesia for fractured neck of femur in the emergency department: a randomized, controlled trial.
We determine whether 3-in-1 femoral nerve block is effective as analgesia for fractured neck of femur when administered by emergency physicians. ⋯ Three-in-one femoral nerve block is an effective method of providing analgesia to patients with fractured neck of femur in the ED. All grades of medical staff were able to apply and consolidate this skill.
