Case ReportsSelective block of nerves in the axillary approach to the brachial plexus.
Optimal surgical conditions for flexor tendon tenolysis in the hand were achieved by ulnar, radial, and musculocutaneous nerve block at the axilla combined with median nerve block at the wrist. ⋯ Palpation of nerves together with a nerve stimulator were used to localize the nerves accurately.

Randomized Controlled Trial Comparative Study Clinical Trial
[General anesthesia vs. retrobulbar anesthesia in cataract surgery. A randomized comparison of patients at risk].
Several studies comparing retrobulbar block (RB) and general anaesthesia (GA) for cataract surgery in the elderly have been published. Most of them were retrospective. Our prospective study was designed in order to determine the benefits or disadvantages using RB or GA. ⋯ Intravenous acetazolamide did not influence ABG in a significant manner. With regard to the preference of each patient, we recommend both RB and GA for cataract surgery in high-risk patients on the assumption of sufficient preoperative treatment of co-existing diseases. In conclusion, cardiovascular and ABG stability were maintained during both anaesthetic techniques.

Randomized Controlled Trial Clinical TrialContinuous low-dose 3-in-1 nerve blockade for postoperative pain relief after total knee replacement.
We have investigated the value of a 3-in-1 nerve block, followed by a continuous low-dose infusion of bupivacaine into the femoral nerve sheath for postoperative analgesia after total knee replacement. Thirty-seven patients were randomly allocated to either a control group or a study group. The study group had a catheter placed in the ipsilateral femoral nerve sheath. ⋯ This was followed by a continuous infusion of 0.125% bupivacaine at 6 mL/h. The study group had significantly lower pain scores 4 and 24 h postoperatively (P less than 0.01) and required less postoperative opioid analgesic medication (P less than 0.01) than the control group. The authors conclude that a continuous low-dose infusion into the femoral nerve sheath results in better pain relief than conventional intramuscularly administered narcotics after total knee arthroplasty.

Randomized Controlled Trial Comparative Study Clinical TrialManipulation of the fractured nose under local anaesthesia.
Simple fractures of the nasal pyramid without significant septal deformity may be reduced as effectively under local as under general anaesthesia. Currently, the former may involve regional nerve blockade by intranasal infiltration and is often unpleasant. We have attempted to find a more acceptable method. ⋯ The surgeon recorded the cosmetic result. Analysis revealed the internal route to be significantly more painful (P less than 0.001) and with no advantage to the patient with respect to post-operative airway patency or cosmesis. We recommend the technically easier external method for this procedure.
