Randomized Controlled Trial Comparative Study Clinical Trial[Pain therapy after thoracotomies--systemic patient-controlled analgesia (PCA) with opioid versus intercostal block and interpleural analgesia].
Both regional analgesia and systemic opioid therapy (e.g. PCA) are commonly used for pain relief following thoracic surgery. Many anaesthesiologists are reluctant to use thoracic epidural analgesia on general surgical wards. ⋯ Intercostal blocks and interpleural analgesia significantly reduce opioid demand following thoracotomy and are effective means of postoperative pain management. Nevertheless, in contrast to epidural analgesia, both methods have to be supplemented by, or combined with, systemic analgesics in most patients. On the other hand, compared to epidural analgesia, ICB and IPA are less invasive and easier to manage on general surgical wards.

[Block of the lateral perforant branches of the subcostal and iliohypogastric nerves for proximal femur surgery].
We describe an original method to block the lateral cutaneous rami of the subcostal and iliohypogastric nerves or'iliac crest point block'to complete plexular block of the lower limb for hip surgery. The local anaesthetic is injected in front of an osterofibrous orifice of the iliac crest. In nine cases out of ten, the lateral cutaneous rami of the iliohypogastric nerve pass through this orifice and in one case out of ten, it is the one arising from the subcostal nerve. This complementary block allows the surgical incision at the level of the great trochanter.

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).
