Salvage and reinfusion of chyle in closed chest injury.

The aim of this study was to describe a system of salvaging and reinfusing chyle which accumulated in the right pleural cavity of a patient after a thoracic duct lesion caused by a closed chest injury associated with amyelic fracture of the dorsal spine D10-D11. The chyle was collected in a reservoir (BT 844 Dideco), transferred by an electronic pump (BT 797 recovery Dideco) to a storage bag, microfiltered and then reinfused to the patient A solution was needed to prevent the patient with severe chylothorax, from having immunological and metabolic imbalance. The long period of conservative treatment with our system was imposed by the onset of acute post-traumatic myocardic infarction which delayed surgery. From experience gained, we can say that using total parenteral nutrition, chyle can not only be salvaged but also reinfused, respecting the strict rules of hygiene.

Antibiotic and antithromboembolic prophylaxis in hip arthroplasty (a review of 700 primary implants).

The authors report the results obtained with antibiotic and antithromboembolic prophylaxis used in 700 consecutive primary total hip arthroplasties. As for antibiotic prophylaxis (5 cases of infection: 0.7%) the various types of antibiotic used always kept the infection rate under 1%, confirming the effectiveness of the preventive use of antibioticotherapy. The incidence of deep venous thrombosis and pulmonary embolia were 3.7% and 0.7%, respectively (26 cases of DVT and 5 of PET). The incidence of DVT rose to 34.4% in a selected group of cases in which phlebography had been carried out even in the absence of symptoms of DVT. This confirms that the routine use of this method would without a doubt be useful in preventing complications with a high risk for the life of the patient (pulmonary embolia). As for pharmacological prophylaxis, indobufene and calcium heparin were the drugs used most: their effectiveness was nearly similar, despite the fact that the use of calcium heparin in patients considered to be at a higher risk for thromboembolic complications should be made clear.

Thromboembolic complications and pharmacological prophylaxis in orthopaedic surgery.

Two thousand, three hundred and three patients who had undergone major orthopaedic surgery were statistically analysed for the incidence of complications comparing three regimens of prophylaxis and coexisting diseases; 2090 patients did not present postoperative complications. PTE occurred in 0.65% (one fatal). The mortality rate was 0.34% and the incidence of haemorrhage (haematoma and one gastric haemorrhage) was 3.8%. Patients treated with indobufen had a shorter hospital stay and the need for homologous blood transfusions was lower than for patients treated with calcium heparin. The rate of PTE was notably different in the three groups, being lower in the group treated with enoxaparin, although this result was not found to be statistically significant.
