[Continuous arteriovenous hemofiltration in acute renal failure. Value of regulating the rate of ultrafiltration].

Continuous arteriovenous hemofiltration (CAVH) requires constant supervision and frequent readjustment of the rate of infusion of the substitution fluid because of variable filtration rate. In order to lighten the management of patients treated with CAVH, an ultrafiltration-pump assisted CAVH was used in 16 patients with oliguric renal failure and cardiovascular instability treated in the intensive care unit. A plate hemofilter (Biospal) was used which is equipped with the high hydraulic permeability AN 69 S membrane. The driving pump was set in order to modulate the ultrafiltration rate from 400 to 1000 ml/h. Ultrafiltration-pump assisted CAVH was given for 8.1 +/- 5.3 days and the filtration volume was 16.3 +/- 3.1 l/day. The mean life span of the hemofilter was 36.4 +/- 27.3 hours. No adverse reaction toward the artificial membrane was detected. Adequate control of fluid balance and electrolyte and acid-base homeostasis were obtained allowing parenteral nutrition. However, in two instances additional hemodialysis was required to adequately control urea generation. Ultrafiltration-pump assisted CAVH proved to be a simple and effective method of fluid removal and urea subtraction by convective transport. Maintenance of stable fluid balance and parenteral nutrition without osmotic disequilibrium was allowed. The pump driven hemofiltration allows optimal use of the filter.

[Problems presented by closed laryngeal-tracheal injuries].

The authors consider the problems raised by severe closed laryngotracheal trauma and report 4 cases. -the immediate tisk to life is due to direct involvement of the respiratory tract requiring emergency measures including cardiorespiratory resuscitation in cases of acute asphyxia. -the origin of the initial respiratory distress, if not obvious from the start, may be suspected in view of the difficulties or impossibility of tracheal intubation, which is also liable to aggravate lesions due to trauma. It is one of these rare cases of resuscitation where emergency tracheotomy is essential. It permits also early, precise surgical exploration. -in cases of fracture of the larynx, a wound of the trachea or rupture and separation of the trachea, the reconstruction must be constructiononstruction must be considered within the first 48 hours. Provision of food and resting of the larynx may be conciliated by installing an esophageal catheter or performing a gastrostomy. Benign trauma, such as contusion or laryngeal commotion, requires close supervision association with medical treatment designed to prevent the onset of lesional oedema.

[Clinical and therapeutic problems posed by hangings. Apropos of 67 cases].

Starting from a collection of 67 cases of hanging taken over by the Anesthesia Resuscitation Department belonging to Reims Hospital University Centre, the authors report their clinical observations and make an analytical confrontation of this type of accident according to various criteria such as: - the initial physical condition of the victims; - the evolution of the symptoms; - the various medical treatments used. The immediate consequences of miscarried hangings lead to a physio-pathological argument dealing mainly with the neurological and breathing manifestations. The elements of this argument enable the writers to back up certain therapeutic orientations among which hyperbaric oxygen therapy and early prescription of which seems to be wished for in the most severe forms of hanging.
