Para-umbilical block: a new concept for regional anaesthesia in children.
This preliminary study describes a new technique to provide analgesia in children undergoing umbilical hernia repair. The para-umbilical block consists of infiltrating the anterior cutaneous branches of the two tenth spinal roots over and under the rectus sheath far from the operative field. Intra and postoperative analgesia as well as operative conditions were assessed in 11 children 16.7 +/- 31 months old, weighing 8421 +/- 6941 g, the block being performed before surgery under light general anaesthesia. ⋯ The block proved to be safe and on the whole effective in this short series. The study should proceed on a multi-centre basis if possible. Indications can be extended.

The evolution of central segmental blockades was studied in 133 patients by using epidural and spinal anesthesias. The efficiencies of 2% Ultracaine (Hoechst) and 2% Lidocaine (Egis) solutions used for epidural anesthesia and 5% Ultracaine (Hoechst) and 0.75% Bupivacaine (Astra) hyperbaric solutions were evaluated. Central segmental blockade induced by Ultracaine was found to be similar to Lidocaine and Bupivacaine in clinical parameters. ⋯ No differences were found in the magnitude of hemodynamic changes both with various anesthetics and different types of segmental blockades. The findings make it possible to regard Ultracaine as an drug that has some advantage over Lidocaine for prolonged epidural anesthesia and similar to the latter in pharmacological characteristics. Ultracaine may be regarded as alternative to Bupivacaine for spinal anesthesia.

Clinical Trial Controlled Clinical Trial[Interscalenic block and surgery of the shoulder. A prospective study of a continuous series of 167 patients].
To determine the relationship between minimal stimulating current and success rate of interscalene brachial plexus block (IBPB), to assess the quality of anaesthesia and postoperative analgesia, and to evaluate the benefits and drawbacks of this technique in shoulder surgery. ⋯ The correlation between minimal stimulating current and success rate has clearly shown the benefit of the nerve stimulation. IBPB, which provides a successful and efficient anaesthesia with minimal risk and satisfactory postoperative analgesia, has become the standard technique for shoulder surgery.

Greater occipital nerve (GON), supraorbital nerve (SON), and minor occipital nerve (MON) blockades-in this sequence-were carried out on the symptomatic side in patients with chronic paroxysmal hemicrania (CPH) (no = 6) and hemicrania continua (HC) (no = 7). Prior to the blockade, indomethacin was discontinued for a sufficiently long time (24 h) to allow a constant flow of attacks/constant pain. The local anaesthetic agent used was lidocaine. ⋯ GON/MON blockades will help distinguish CPH/HC from cervicogenic headache. SON blockade will have to be carried out in a good-sized series of HC patients in order to establish more concrete evidence of the putative effect in HC. SON blockades may eventually also aid in the distinction between HC and supraorbital nerve neuralgia (where the blockade effect generally seems to be complete).
