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.

Case Reports[Lethal portal venous gas after cardiopulmonary arrest].
We report the case of a 51-year-old patient admitted after a transient cardiorespiratory arrest. The abdominal CT scan revealed the presence of hepatic portal venous gas. ⋯ Necrotic bowel is associated with hepatic portal venous gas in 50% of the cases and the current mortality rate is 85%. Gas originates either through intestinal transmucosal passage, either by intraportal bacterial gas production, or through both mechanisms.

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.

Comparative Study Clinical Trial[Continuous analgesia with a femoral catheter: plexus or femoral block?].
To evaluate the spread and quality of sensitive blockade produced by continuous and prolonged use of a femoral catheter inserted for postoperative analgesia. ⋯ In most patients, a local anaesthetic administered continuously via a femoral catheter produces a blockade limited to the femoral nerve. These data do not substantiate the conclusions by those who consider they are producing a continuous "3 in 1" block with this technique. However, it is obviously not essential to produce a sensitive blockade of the three main nerves of the lumbar plexus to obtain an effective analgesia after knee surgery.

To review current data on butyrylcholinesterase. ⋯ Butyrylcholinesterase must be differentiated from acetylcholinesterase, which cannot hydrolyse succinylcholine. The physiological action of butyrylcholinesterase remains unknown, although it can hydrolyse many drugs. Excluding genetical mutations, several physiopathological situations alter butyryl-cholinesterase activity. Butyrylcholinesterase activity assessment does not allow the diagnosis of genetic variants. Whatever the origin, only deficits of more than 50% modify significantly the metabolism of succinylcholine or mivacurium. The diagnosis of a prolonged neuromuscular blockade is obtained with systematic monitoring of the neuromuscular function in case of administration of mivacurium or succinylcholine. Mivacurium should only be re-injected when one response at train of four is obtained. In case of prolonged neuromuscular blockade, the anticholinesterasic agent should not be administered when no response at train of four is obtained. The biochemical methods using inhibitors (dibucaine, fluoride) of the butyrylcholinesterase and a familial study lead to the diagnosis in most cases because the atypical and fluoride variants are the most frequent. When results are doubtful, genetic molecular methods with the use of PCR and restriction enzymes allow a rapid diagnosis.
