[Pulmonary oedema after late revascularisation of the lower limbs (author's transl)].

In the two cases reported, pulmonary oedema developed immediately following revascularisation of the lower limbs after prolonged ischaemia. Without it being possible to formally exclude the possible role of a haemodynamic factor, the authors suggest the hypothesis of a predominantly lesional mechanism. The "reconnection to the circuit" is the provoking factor in this oedema, the alveolo-capillary membrane being previously altered by the prolonged ischaemia, infection and massive transfusion. The pulmonary manifestations would seem to enter within the classification of somatolysis.

[Perforations of the dura mater during epidural anesthesia. The value of epidurography].

The authors propose a pathogenic classification of perforations of the dura mater occurring during continuous epidural anaesthesia: according to the flow through the communication with the subarochnoid space. Two clinical forms of anaesthesia affecting the cord itself may be distinguished on this basis, one frequent and of immediate onset, diagnosed by the "test dose" and the other rare, of delayed onset, where this safety measure does not suffice. Routine prior epidurography is suggested, in order to ensure the diagnosis of dura mater perforation. In the case of the latter, it show either a more or less typical appearance of radicolography only or, more rarely, a picture which combines opacification of the epidural space with the subarachnoid passage of the contrast medium. This "mixed" appearance, although rare, should be known since it makes it possible to prevent delayed total spinal anaesthesia.

[Methods and indications for low peridural analgesia in the aged. Report of 300 cases].

Continuous peridural analgesia took a long time to be accepted in current practice in surgery of the elderly, owing to the apprehensions for the possible cardiovascular consequences and also, the difficulty in using this form of anaesthesia in the elderly. The experience of more than 300 cases, collected in the Nice department of Anesthetics and Intensive Care, has shown that: 1--technical failures are exceptional with routine use of prior epidurography; 2--its indications depend on the site and type of surgery and on the clinical conditions of the patient; 3--until now, there have been no severe complications due to this method whatever the degree and number of morbid conditions; 4--in the elderly subject, the importance of problems of pre and post-operative analgesia have led us to enlarge the indications for long-term peridural analgesia. Peridural anesthesia may be used as a routine when the site of the operation involves areas situated below the IXth metamere. This shows its importance in surgery in the elderly.

[Epidurography in the continuous peridural anesthesia technic in geriatric surgery].

The radiographic opacification of the peridural space was carried out prior to any injection of anaesthetic solution, both in the interest of security and to maximize the chances of success, on a homogeneous series of patients of more than 75 years of age, benefiting from continuous peridural analgesia. The following observations are made: - the direction of the catheter is ascending in 94 p. 100 of the cases, - the frequency of malpositions seems to increase with the lenght of the catheter introduced into the space, - the images obtained by injections of the radio-opaque agent are sufficiently specific to allow verification of the extra-dural situation of the apex of the catheter, - the permeability of the intervertebral foramina is found in 36 p. 100 of the cases, - the unilateral blocks appear to be exceptional, the technical difficulties inherent in the effects of aging on the vertebral system being compensated for by the constant success whenever the peridural space is reached.
