Prevention of radiation injuries to the small intestine.

The removable synthetic "pelvic spacer" prevents intestinal loops from sliding down into the area most heavily exposed to irradiation during a full course of radiotherapy for abdominopelvic neoplasia. Furthermore, it provides a homogeneous distribution of roentgenograms and allows higher dosages of radiation. It reduces possible sequelae and offers new possibilities for radiotherapy of tumors of the pelvis. The removal of the spacer is disadvantageous but clearly compensated by a more curative treatment.

Epidural analgesia or mechanical ventilation for multiple Rib fractures?

A protocol for treating thoracic trauma is proposed. Severe pulmonary lesion with increased venous admixture (e.g. contusio, atelectasis, aspiration) is treated by mechanical ventilation. Rib fractures with minor pulmonary lesion and therefore with only moderately abnormal gas exchange but with remarkably reduced vital capacity (even with flail chest) are controlled by thoracic epidural analgesia following vital capacity, tidal volume and respiratory rate. If both a severe pulmonary lesion and serial rib fractures are present, the patient is ventilated for 2-3 days and then extubated to breath spontaneously with epidural analgesia. The indication for a mechanical ventilation or for spontaneous breathing with thoracic epidural analgesia is therefore deducted more from functional variables than from morphological facts. The course of a consecutive series of 283 patients is presented. 155 patients were treated with primary ventilation and 112 patients with primary epidural analgesia, while 16 patients could be managed with general analgesia. The duration of treatment morbidity and mortality show this protocol to be very useful.

Respiratory assistance on surgical wards with continuous positive airway pressure (Turbo-PEEP-Weaner).

Based on our own experience, we introduce a new continuous positive airway pressure device. The patient can breathe continuously positive airway pressure through a tight face mask, and thus the postoperative reduction in functional residual capacity is counteracted. This is shown by the well-documented clinical course of a 62 year old man who had respiratory insufficiency after proximal selective vagotomy.

[Thoracic epidural analgesic (TEA) or controlled ventilation in the treatment of patients with multiple rib fractures (author's transl)].

In the last seven years 283 trauma patients were treated for multiple rib fractures and/or flail chest. Primary management consisted of only morphine analgesia in 16 patients, TEA in 112 patients, and mechanical ventilation in 155 patients. The indication for mechanical ventilation was always associated injuries (cerebral contusion, para- and tetraplegia, aspiration, severe lung contusion) and not the instability of the thoracic cage.

[Diagnosis of intra-abdominal bleeding--comparison of peritoneal lavage and laparoscopy].

By peritoneal lavage, patients with abdominal trauma can be categorizied into: I. strongly positive = frank bleeding into the abdominal cavity; II. negative = no danger of bleeding; III. only small amounts of blood staining the lavage = watching policy by repeating the peritoneal lavage. Out of 132 PL, 33 were not conclusive in the first attempt. During the course, 9 of these had to be operated upon, whereas 24 could be spared a laparotomy by our watching policy. As to accuracy, there is no doubt that peritoneal lavage is outstanding and cannot be outweighed by laparoscopy. The same is true as to rapidity. In a retrospective study concerning 100 patients with blunt abdominal trauma and intraabdominal bleeding, we found that with peritoneal lavage 75% could be diagnosed within two hours following admittance, whereas our laparoscopy team reached the same in only 26% of the patients.

[Results following Trillat's surgery in habitual shoulder dislocation].

Following a review of the surgical methods to correct habitual dislocation of the shoulder we report on the method and the results of the Trillat procedure. The first 13 patients operated upon have been investigated 1 1/2 to 3 1/2 years postoperatively. All remained free of recurrence; the mean loss of external rotation was 13 degrees. Subjective results showed that 11 out of 13 patients were satisfied or highly satisfied.

[Spontaneous rupture of the oesophagus. Report of two cases].

Case report of two so-called spontaneous ruptures of the oesophagus. The early diagnosis saved one of the patients, in the other the sequelae of the oesophagus rupture were treated successfully by intensive care. He died one month later from stress ulcers in the stomach and duodenum.

Effect of hemorrhagic shock on intrapulmonary right-to-left shunt (QS/QT) and dead space (VD/VT).

The effect of hemorrhagic shock on intrapulmonary right-to-left shunt and dead space ratio was investigated in spontaneously breathing dogs under barbiturate anesthesia. Intrapulmonary right-to-left shunt was reduced sufficiently to offset the marked increase in arteriovenous oxygen difference and PaO2 did not fall. Dead space ratio was increased markedly; therefore, in shock, sufficient CO2-elimination depends on severe hyperventilation. According to this empirical findings, a decrease in PaO2 in shock must not be interpreted as a consequence of the shock itself, but it implies an additional pulmonary pathology.
