The techniques of continuous peripheral blockades have shown to be efficient in postoperative pain control, in the various orthopaedic procedures of the limbs. The aim of this study is to evaluate the existing data about the use of a continuous blockade of the lumbar plexus or femoral nerve, together with the indications for technique and therapy. ⋯ The use of continuous blockades of the lumbar plexus or femoral nerve shows to be an important and effective instrument not only in terms of positive effects on postoperative pain control, but also in terms of relevant advantages concerning final outcome after surgery. Nevertheless these techniques should not be considered as the only approach to postoperative pain in the orthopaedic patient, but have to be included in a global, multidisciplinary and multimodal approach.

In this review, some of the newer developments in regional anaesthesia (RA) are discussed. The relationship between paraesthesiae and nerve stimulator responses has been shown to be unclear, and sometimes at a needle tip location where a paraesthesia is found, there is no response to the nerve stimulator. It is recommended to use whichever end point is found first. ⋯ The use of PCA for blocks as well as intravenously and the extension of the use of RA into the home are important developments. The beneficial effects of RA on postoperative morbidity and mortality are becoming clearer, and the introduction of the two new local anaesthetic agents, ropivacaine and levobupivacaine have improved safety. There has, however, been very slow progress in the development of long awaited ultralong acting local anaesthetics or in the introduction of slow release formulations.

Regional anaesthesia in vascular surgery: a multidisciplinary approach to accelerate recovery and postoperative discharge.
A multimodal, rehabilitative, fast discharge approach to abdominal aortic surgery is analyzed. The approach was developed in two phases during the years 1997-2000: in the first phase (1997) patients had thoracic epidural anesthesia plus TIVA and analgesia. ⋯ Preliminary results on 44 patients show no mortality, low postoperative morbility (cardiac complications 2,2%, peripheral embolization 2,2%, no pulmonary complications), no ICU stay and fast hospital discharge (median: 3,5 days, range: 2-8 days) without complications. We conclude that preliminary data support the safety and the need for further improvement of a multimodal, aggressive rehabilitative approach in abdominal vascular surgery.

Case Reports[Severe and prolonged post-dural puncture headache: from pathological basis to therapeutic role and correct timing for epidural blood patch].
Believed to be due to unbalance between cerebrospinal fluid (CSF) production rate and its loss through the spinal dural puncture hole, post-dural puncture headache (PDPH) is often considered as a physiological syndrome, usually reversible without pathological sequelae after dural hole's closure. The clinical case here presented (incapacitating headache associated with diagnostic dural puncture in a leukaemic young female patient who underwent bone marrow transplantation) shows potentially fatal pathological sequelae following prolonged headache (untreated, due to the severe postransplant immunodeficiency and coagulopathy). The observed RMI lesions suggest interesting conclusions about the clinical indications and correct timing of autologous epidural blood patch (EBP). We also suggest the ways to preventing rebound intracranial hypertension following autologous epidural blood patch in patients suffering from incapacitating and prolonged headache.

Randomized Controlled Trial Comparative Study Clinical Trial[S(-) bupivacaine (levobupivacaine) in peripheral blocks: preliminary results].
We have compared the onset time, anesthetic potency and adverse effects of three local anaesthetics (ropivacaine, levobupivacaine and bupivacaine) in two type of peripheral blocks (brachial plexus block for upper limb and femoral nerve block for lower limb) in adult patients in a double blind, randomized, prospective study. A total of 66 patients undergoing orthopaedic surgery were randomly allocated to receive brachial plexus block or femoral nerve blockade with 0,5% ropivacaine (group R, n=22), 0,5% levobupivacaine (group L, n=22) or 0,5% bupivacaine (group B, n=22), each groups has been divided into two subgroups (LBP n=11, RBP n=11, BPB n=11, LBF n=11, RBF n=11, BBF n=11) dipending on the type of block. The onset of sensory nerve block was similar for the three groups; the onset of motor block and onset time ready to surgery were faster in group R (-30%) if compared with group L and B. ⋯ We did not observe any adverse effect. We conclude that ropivacaine acts faster with less interpatient variability, while levobupivacaine and bupivacaine offer a prolonged postoperative analgesia. For this reason, with the exception of bupivacaine due to major cardio and neuro toxicity, we can indifferently use levobupivacaine or ropivacaine depending on the requested characteristics of the anesthetic.
