[Oropharyngeal ulcers following anaesthesia with the laryngeal tube S].

We report a case of acute tongue and uvula ulcerations consecutive to the use of a laryngeal tube Sonda (LTS) for airway management. The LTS was used during general anaesthesia for hysteroscopy and resection of endometrial hyperplasia. No trouble occurred during LTS insertion and anaesthesia. Symptomatic treatment provided complete resolution within a few days. This event points out the potential risk of more serious lesions.

[Neurological accidents after epidural anesthesia in obstetrics].

Several neurological complications have been described after epidural anaesthesia, including direct trauma to the spinal cord or nerve roots, epidural haematoma, meningitis, epidural abscess, spinal cord infarction. neurologic toxicity of injected agents. In obstetric practice, these complications are very uncommon. However, their real occurrence may be underrated, partly for medicolegal reasons. Different complication mechanisms are described; they should be kept in mind while evaluating post block neurological deficits so that prompt corrective measures can be taken whenever appropriate to prevent permanent damage.

[Hemodynamic changes during celioscopy: a study carried out using thoracic electric bioimpedance].

In 18 women A.S.A. physical status 1, a noninvasive thoracic electrical bioimpedance method was used to evaluate haemodynamic changes during gynaecological laparoscopy. A significant decrease in cardiac index was observed after peritoneal insufflation, from 3.2 to 2.8 L.min-1.m-2 and returned to the initial values after ten minutes of Trendelenburg's position. Elevated intra-abdominal pressure was also associated with a significant increase in mean arterial pressure (from 68 to 88 mmHg) and systemic vascular resistance index (from 1620 to 2491 dyn.s.cm-5.m-2). However, values were not restored after peritoneal exsufflation: systemic vascular resistance index values remained 30 per cent higher than that before insufflation. Decreased venous return may account for the significant decrease in cardiac output but mechanical compression does not explain the persistent elevation of systemic vascular resistance.

[Mendelson's syndrome in obstetrics. History or fact?].

The authors analyse Mendelson's original article on the lung disorders caused by inhalation: the clinical aspects, the etiological aspects of the pathology and above all preventive measures to be taken. These are still all of importance. The epidemiological incidence of this condition was tackled by the slant of the INSERM enquiry conducted on the anaesthetists on the one hand and by a retrospective enquiry by the University Department in Bordeaux on the other hand. Reviewing the literature shows that traditional methods of treatment have to be re-examined. These are: pulmonary lavage, treatment with corticosteroids and progress which has been made parallel with progress in respiratory resuscitation especially in severe forms of the condition. Prevention is the most important feature. Endotracheal intubation needs to be carried out when general anaesthetics are employed. The use of anti-H2 substances is increasing. All the same, the most decisive steps will be taken when more local regional anesthesia is used. This should be started in labour wards by further use of epidural analgesia.

[Acute fibrinopenia in obstetrics].

A review of 10 cases of severe obstetrical haemorrhage is presented. The etiology is not always clear. The most significant biological sign is the early, acute and marked drop of fibrinogen levels, below 1 g in 20 p. cent of the cases and 0.5 g in 50 p. cent. An early and rapid treatment is essential and based on correcting the fibrinopenia; fibrinogen, in fractioned form, at a mean dose of 3 g, reduces the duration of the syndrome and minimize the risks of complications. In the acute phase, heparin therapy must be avoided because it might aggravate the haemorrhage.

[Comparative study of 2 simple methods of measurement of cardiac output].

The authors compare two methods of simple measures of cardiac output which may be achieved using "bedsides procedures": the thermodilution and the isotopic embolism. The correlation of both series of measures is statistically significant. Besides, each method shows certain constraints. It brings different complementary hemodynamic informations.

[Apropos of 164 aortographies performed with diazepam neuroleptoanalgesia].

The authors report their experience with the use of a semi-conscious anesthetic technique for translumbar angiography of the abdominal aorta by the means of diazepam neurolept analgesia. This technique permits gathering all the data necessary for the angiographic examination. It is easy to manipulate and enables a certain comfort for asthenic patient.

Late reoperations after aorto-iliac restaurations.

(1) Late thrombosis after aorto-iliac revascularisations are infrequent when the operation is correctly performed and controlled by intra-operative angiography. (2) Reoperation after thromboendarterectomy is a difficult procedure requiring great care in the aortic approach. (3) Reoperation after thrombosis of a prosthetic graft is much easier as far as dissection is concerned, usually the upper part of the former prosthesis may be kept, which renders the procedure very much easier. (4) The distal anastomosis should be realised distally to the sclerotic block surrounding the femoral bifurcation. (5) In case of poor risk patients, it is better to use extra-anatomical bypasses, and if necessary, one must be able to sacrifice a limb for a life. Mortality rates are high in our series. It may be due in part to a too much optimistic pre-operative evaluation and selection of our patients, in the first years of our experience.
