Interpleural analgesia is a method of postoperative analgesia that was developed by Kvalheim and Reiestad in 1984. The main indication is postoperative pain after unilateral thoracic and upper abdominal surgery. Many authors report good analgesic effects and better postoperative lung function following cholecystectomy. ⋯ The local anaesthetic of choice is bupivacaine (in concentrations of 0.25-0.75%, injection volumes of 10-40 ml, with or without epinephrine, applied as bolus or infusion), but others, such as lidocaine or morphine, are also being tested. Risks involved in this method are pneumothorax when the catheter is placed blind and the systemic toxicity of the local anaesthetic. This review provides information on the mechanism of action, the technique, the clinical use to date and possible risks.

A review of the literature suggests that patients with tension headache do not differ from normals as much as from each other in psychological traits. The aim of the present study was to identify psychological subtypes of tension headache patients. ⋯ The results are discussed with reference to the literature and to indications for psychological treatment interventions.
