Review[Antibiotic prophylaxis of penetrating injuries of the abdomen].
Antibiotic prophylaxis for a penetrating injury of the abdomen has a distinctive feature as contamination occurs before administration of antibiotics and because important blood loss can modify the pharmacokinetics of antibiotics. Due to the rate and severity of infectious complications, no controlled study has been undertaken. ⋯ Various antibiotic regimens have been administered, but it seems that those using an antibiotic active against anaerobes are more efficient to prevent postoperative infectious complications than without them. There is no benefit to administer antibiotics for more than 24 hours.

The abdominal pressure is a hydrostatic one, which can be measured in the bladder, the rectum and the stomach. In physiologic conditions, the abdominal pressure is variable, with peaks as high as 100 to 200 mmHg at the time of defecation, cough. The increase in abdominal pressure elicited by abdominal distension or compression acts directly on the abdominal compartment, indirectly on the thoracic compartment, and modifies the circulation and the ventilation. ⋯ The risk of regurgitation associated with an increased abdominal pressure must also be kept in mind. The abdominal pressure plays an important role in anaesthesia as well as in surgery. Therefore its measurement, which is easy, should become a routine.

In elective colorectal surgery, the benefit of preoperative antibiotic prophylaxis is well established, with a reduction in wound infection rate to less than 10%. The antimicrobial agent used has to be active against aerobic and anaerobic pathogens such as Escheria coli and Bacteriodes fragilis. The efficacy of three schemes of administration: oral and/or parenteral prophylaxis associated with a mechanical preparation, has been demonstrated. ⋯ Parenteral prophylaxis with a cephalosporin active against Bacteriodes fragilis such as cefoxitin and cefotetan, is preferred in Europe. The issue of whether a systemic prophylaxis should be added to the oral regimen or not has not yet been resolved. However it seems that the association should be proposed in various situations: patients with a high risk factors score (rectal resection and operations lasting more than three hours), patients with incomplete mechanical preparation, delay of the onset of surgery after the last oral dose.

[Training evaluation of the nursing staff in patient-controlled analgesia].
Intravenous patient-controlled analgesia (PCA) is an effective technique to relieve most forms of acute postoperative pain. However it is not easy to apply. An adequate training of the nursing staff has been for a safe and successful use in the recovery room and the wards as well. ⋯ There is no longer any resistance against the introduction of PCA in the wards. Training of nursing staff for the use of PCA devices is essential in order to avoid "human errors". PCA has become routine for the management of postoperative pain.

Case Reports[Brown-Séquard syndrome after closed injury of the cervical spine].
The case of a Brown-Séquard syndrome at the C5 level, in a 21-year-old young man after a traffic accident is reported. Initially, the symptoms of spinal injury were concealed by those related to head and face trauma. The neurologic assessment showed a hemiplegia located in the same side as the medullar injury with a controlateral thermo-algesic anaesthesia. ⋯ Six weeks later, the patient was again able to walk. However the thermo-algesic anaesthesia remained unchanged. This case report underlines the necessity of a careful and complete neurologic assessment of trauma patients and reminds of the possibility of occurrence of a Brown-Séquard syndrome in them.
