Pain is a subjective feeling; its assessment is therefore difficult, and no "gold standard" method exists for humans. Major improvements have, however, been made in the last decade by widespread acceptation of the concept of pain evaluation and widespread use on surgical wards. Evaluation by the patient himself is the rule (unless communication is impaired), as assessment of pain by nurses or doctors systematically leads to underestimation (which also occurs with observational scales). ⋯ Although scientific validation is difficult, VAS seems the most accurate and reproducible scale. Post-operative pain should be assessed several times a day in every patient, at rest and in dynamic conditions (cough, movement) and should focus on present pain rather than on pain in the previous hours. Assessment of pain is essential before quality-assurance programmes can be implemented.

[Pressure-controlled mechanical ventilation: a simplified titration method of the extrinsic positive expiratory pressure].
Extrinsic positive end-expiratory pressure (PEEPe) may improve gas distribution within the lungs, induce alveolar recruitment or, conversely, produce pulmonary overdistension, and modify the respiratory impedance. Under pressure-controlled mechanical ventilation (PCV) this phenomenon modifies the minute ventilation and the dynamic compliance of the respiratory system (Crs,dyn). This study was aimed to assess the incidence of a significant gain in Crs,dyn under the effect of PEEPe during PCV. ⋯ In 50% of the studied patients a significant gain in Crs,dyn was found, allowing a less traumatic PCV. These results suggest the clinical usefulness of this method of titration of PEEPe, which requires neither specific devices nor a disconnection of the patient.

Review[Frequency, intensity, development and repercussions of postoperative pain as a function of the type of surgery].
Type of surgery is the most important factor conditioning intensity and duration of postoperative pain. Thoracic and spinal surgery are the most painful procedures. Abdominal, urologic and orthopedic surgery lead to severe postoperative pain. ⋯ The surgical procedure is the major determinant of metabolic and psychologic postoperative deterioration. Adequate pain relief allows postoperative rehabilitation and physiotherapy programmes after abdominal and orthopaedic surgery. This could be expected to reduce hospital stay and improve convalescence.

Until some years ago, patients suffering from head injury were poorly fed and nutrition was not a primary concern in the medical treatment of these patients. To date, six studies on head-injury patients have examined the effect of nutritional support on their outcome. All showed that lack of adequate nutrition contributed to increased mortality and morbidity. ⋯ Moreover, it enables early enteral administration of nutrients in a safe and efficient way. Early administration of nutrients may be extremely important as it seems to decrease the hypermetabolic response to traumatic injury. Therefore, early jejunal enteral feeding may become an important cornerstone in the medical management of head-injured patients.
