[Axillary blockade of the brachial plexus. A prospective evaluation of 1133 cases of plexus catheter anesthesia].
The results of 1133 axillary catheter brachial blocks are reported. Effectiveness and side-effects were monitored in a prospective manner over a period of 1 year. ⋯ Surgery was completed in 72% of patients; 24% required some form of supplementation including 17.2% of patients who received a "top-up" after 20 min (Table 1). In 3.8% of cases the technique was considered to be a complete failure, meaning that patients needed some type of general anesthesia including the use of i.v. ketamine.(ABSTRACT TRUNCATED AT 250 WORDS)

Sciatic nerve block was performed in two groups of patients using a low power peripheral nerve stimulator to aid nerve location. In group A 1% prilocaine with felypressin was used as the local anaesthetic agent in a volume of 0.25 ml/kg body weight. ⋯ Use of the 3% solution resulted in highly significant reductions in the mean latency for analgesia of the nerve block and in the latency and degree of motor block achieved (p less than 0.005 in each case). The clinical value of high concentration, low volume nerve block is discussed.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of bupivacaine and alkalinized bupivacaine in brachial plexus anesthesia.
To define the effect of alkalinization of bupivacaine 0.5% in subclavian perivascular brachial plexus blockade, the time to onset, time to peak effect, and 6-hour regression of sensory and motor blockade were determined. Sixty physical status ASA I and II patients were randomly allocated to one of two groups and a double-blind design was used: group I (n = 30) received bupivacaine 0.5% (pH, 5.5) 3 mg/kg, while group II (n = 30) received alkalinized bupivacaine 0.5% (pH, 7.05-7.15) 3 mg/kg. Onset and regression of sensory blockade were determined by pinprick in the C4-T2 skin dermatomes, while motor blockade was assessed using a scheme of proximal to distal muscle group paralysis. ⋯ Similarly, no difference in time to onset of motor blockade (group I, 6.9 +/- 1.7 min; group II, 6.3 +/- 1.5 min) or time to peak motor effect (group I, 18.1 +/- 1.9 min; group II, 15.1 +/- 1.9 min) was observed. Regression of postoperative sensory and motor blockade was similar in both groups. It is concluded that alkalinization of bupivacaine 0.5% solutions does not confer any added clinical advantage in subclavian perivascular brachial plexus blockade when compared with commercially available bupivacaine.

Pulmonary complications after upper abdominal surgery: their prevention with intercostal blocks.
A prospective study of postoperative pulmonary complications (PPC) appearing during the hospital stay was carried out in 417 patients undergoing surgery through a subcostal or midline incision. Postoperative pain was relieved either by intercostal block and centrally-acting analgesics on demand or by centrally-acting analgesics alone. Pulmonary complications were diagnosed from combined physical and radiological signs. ⋯ Indeed, an increased rate of PPC was found in our patients over the age of 60 who had received bilateral intercostal blocks. Irrespective of the type of incision, surgery or method of postoperative pain relief, the patients with PPC more often had respiratory or other disorders preoperatively or a surgical complication intra- or postoperatively than those with normal postoperative recovery. Predisposing physical factors and high age were more common among the patients developing PPC in spite of treatment with intercostal blocks compared to those without such treatment.
