Randomized Controlled Trial Comparative Study
Etomidate-Lipuro is associated with considerably less injection pain in children compared with propofol with added lidocaine.
Propofol is associated with a high incidence of injection pain in children, even if given together with lidocaine. A new lipid formulation of etomidate (Etomidate-Lipuro) has been found in adults to cause very little discomfort during i.v. injection. The aim of the present prospective, double-blind, randomized trial was to compare the incidence of injection pain during i.v. induction of anaesthesia between propofol with added lidocaine (previous standard) and this new etomidate formulation in paediatric patients. ⋯ The use of a new lipid formulation of etomidate is associated with significantly less injection pain than propofol with added lidocaine in children. This finding may warrant a change in clinical practice in order to avoid unnecessary pain in children.

Predicting response to recombinant factor VIIa in non-haemophiliac patients with severe haemorrhage.
Despite increasing use of recombinant factor VIIa (rFVIIa) in non-haemophiliac patients, it is unclear when rFVIIa might be effective. ⋯ High SOFA score and failure to respond to one adequate dose of rFVIIa appear to identify patients with poor prognosis. These observations may help in determining when rFVIIa treatment is likely to be futile.

Comparison of lactated Ringer's, gelatine and blood resuscitation on intestinal oxygen supply and mucosal tissue oxygen tension in haemorrhagic shock.
To evaluate the effects on intestinal oxygen supply, and mucosal tissue oxygen tension during haemorrhage and after fluid resuscitation with either blood (B; n=7), gelatine (G; n=8), or lactated Ringer's solution (R; n=8) in an autoperfused, innervated jejunal segment in anaesthetized pigs. ⋯ Blood or gelatine infusion improves mucosal tissue oxygenation of the porcine jejunum after severe haemorrhage when compared with lactated Ringer's solution.

Identification of postoperative patients at high risk of dying early after intensive care unit (ICU) admission through a fast and readily available parameter may help in determining therapeutic interventions or further diagnostic procedures that could have an impact on patients' outcome. The aim of our study was to assess the utility of procalcitonin (PCT) and other readily available parameters, as useful early (days 1-3) predictors of mortality in postoperative patients diagnosed with severe sepsis within 24 h preceding their operation. ⋯ PCT exhibited no discriminative power early after ICU admission for prediction of mortality in critically ill patients with severe sepsis, compared with a high predictive power of SOFA score on day 3. However, using PCT could still serve as a useful complementary comparator for prediction of survival outcome using the SOFA score.

This study was conducted to assess whether the combined administration of fibrinogen and prothrombin complex concentrate (PCC) enables the reversal of dilutional coagulopathy resulting from intended blood loss and fluid replacement, and whether this treatment reduces further blood loss and mortality. ⋯ During haemodilution, substitution of fibrinogen and PCC causes an enhancement of coagulation and final clot strength. This reversal of dilutional coagulopathy may reduce blood loss and mortality when large amounts of colloids are needed to maintain normovolaemia during huge blood losses.
