Twenty patients undergoing a posterolateral thoracotomy for lung resection or a nonpulmonary procedure were divided into four groups. Group 1 was the control group. Patients in Group 2 had an intercostal nerve block at the time of closure. ⋯ It is concluded that bedside spirometry is a simple and reliable technique to assess postoperative changes in ventilatory mechanics due to pain. The pain that follows posterolateral thoracotomy can be substantially decreased with a continuous intercostal nerve block. Anterolateral thoracotomy is notably less painful than posterolateral thoracotomy and should be considered the approach of choice for patients with decreased pulmonary reserve who undergo uncomplicated pulmonary resection.

Supraclavicular brachial plexus block with the aid of a nerve stimulator.
Hundred supraclavicular brachial plexus blocks according to the subclavian perivascular technique were performed with the aid of a nerve stimulator Neutracer in order to verify the value of the technique and the acceptance by the patients. The technique is extensively described and the results and complications are presented. The rationale for the use of the supraclavicular approach and the advantages of the use of a nerve stimulator in regional anesthesia are discussed.

Perivascular axillary block IV: blockade following 40, 50 or 60 ml of mepivacaine 1% with adrenaline.
Perivascular axillary blockade was performed on 90 patients with the aid of a catheter technique. The patients were randomly allocated to receive either 40, 50 or 60 ml of 1% mepivacaine with adrenaline 1:200,000. Blood concentrations of mepivacaine were measured up to 90 min after injection in seven, eight and ten of the patients from the three groups. ⋯ None of the 90 patients showed any signs of systemic toxic reactions. The mean peak values of blood concentrations were 0.5-1.0 microgram/ml higher in the groups given 50 ml and 60 ml than in the group given 40 ml. On the basis of the present and two previous investigations on the dose response in perivascular axillary blockade, a dose of 50 ml 1% mepivacaine with adrenaline or another equivalent drug with vasoconstrictor is recommended.

Perivascular axillary block III: blockade following 40 ml of 0.5%, 1% or 1.5% mepivacaine with adrenaline.
Perivascular axillary blockade was performed on 90 patients with the aid of a catheter technique. All blockades were performed by the same anaesthetist, who practised perivascular axillary blockade three or four times a day. The patients were randomly allocated to three groups. ⋯ All three groups showed a high incidence of analgesia (70%-100%) in all cutaneous segments, and none of the blockades showed total failure of the sensory blockade. The lowest incidence of sensory blockade was found in the areas innervated by the axillary, the radial and the musculocutaneous nerves, but no difference was found between the groups. However, the motor blockade was found to improve with increasing concentration of local anaesthetic solution.

Alcohol blockade of the inferior dental nerve under radiographic control in the management of trigeminal neuralgia.
A classification of the various treatments available for controlling the pain of trigeminal neuralgia is given. The cause of this disorder remains unknown. ⋯ Radiographic localization of the position of the needle tip prior to the injection of alcohol is described. It is suggested that this technique gives more reliable results, with fewer side effects, and reduces the volume of the alcohol injection required.
