ReviewIs magnesium sulfate by the intrathecal route efficient and safe?
The polypharmacological approach to the treatment of postoperative pain has become routine in an attempt to minimize the adverse side effects of opioids. Magnesium sulphate is a noncompetitive antagonist of the N-methyl-d-aspartate (NMDA) receptor and thus can modify nociceptive modulation. ⋯ Several studies have shown that the administration of magnesium by the intrathecal route is safe and, in combination with opiates, extends the effect of spinal anaesthesia in both animal and human studies. The analysis of these studies justifies further investigation of the use of magnesium sulphate by the intrathecal route.

Clinical Trial[Tranexamic acid reduces haematomas but not pain after total knee arthroplasty].
Tranexamic acid (TxA) reduces total blood losses (TBL) and allogenic transfusion (TH) after total knee arthroplasty (TKA). TBL can be external (surgical field, drains), or hidden (haematomas). Haematomas induce pain and limit postoperative rehabilitation. The aim of the study was to evaluate if TxA reduces haematomas and pain after TKA. ⋯ After TKA, TxA reduces the volume of hematomas, without any improvement in analgesia and rehabilitation until the sixth postoperative month.

[Agreement between lung ultrasonography and chest radiography in the intensive care unit].
Because the chest radiograph currently remains the routine choice of imaging for the examination of the chest in the intensive care unit, we compared lung ultrasonography with chest radiography. ⋯ There was only moderate agreement between lung ultrasonography and chest radiography for the diagnosis of interstitial syndrome, alveolar consolidation and pleural effusion in intensive care unit. This result is mainly explained by the higher number of ultrasound abnormalities. With the ability to provide fast diagnosis, good reproducibility and high feasibility, ultrasound scan could represent an alternative exam for chest exploration in intensive care unit.

Case Reports[Postpartum reversible cerebral angiopathy: an unusual cause of headache].
We present the case of a 34-year-old woman who developed, in postpartum period of an uncomplicated pregnancy, a thunderclap headache with visual disturbance associated with a severe arterial hypertension. Both clinical evolution and cerebral imaging including angio-MR confirmed the diagnosis of postpartum reversible vasoconstriction syndrome. One of the leading causes of this syndrome is the use of vasoactive drugs as it was observed in the case of this patient. It is important to consider this syndrome in the differential diagnosis in patients presenting with headache in the postpartum period.
