Review[Regional analgesia after lower limb orthopaedic surgery].
To provide postoperative analgesia, the anaesthesist has at his disposal a panel of different medications and also regional techniques of neural blockade. Loco-Regional analgesia (epidural or peripheral nerve block), by the use of local anaesthetics, blocks conduction of the painful influx to th central nervous system. Pain relief using peripheral nerve blocks after lower limb surgery represents as good alternative to the epidural analgesia and is superior to controlled analgesia with morphine. ⋯ Analgesia after total knee prosthesis and hallux valgus surgery has considerably evolved. Postoperative analgesia is important in these cases: it facilitates physical therapy and improves patient's rehabilitation and satisfaction, it also shortens hospital stay. The aim of this review is to explain the different techniques of peripheral neural blockade and assess the value of this technique for the postoperative period after these two surgeries.

[Treatment of severe preeclampsia: until when and for what risks/benefits?].
The four major hypertensive disorders related to pregnancy are preeclampsia, chronic hypertension, preeclampsia superimposed upon chronic hypertension, and gestational hypertension. The development of hypertension and proteinuria in pregnancy is usually due to preeclampsia, particularly in a primigravida. These findings typically become apparent in the latter part of the third trimester and progress until delivery, but some women develop symptoms in the latter half of the second trimester, or intrapartum, or the early postpartum period. ⋯ Antihypertensive treatment aims at protecting the mother from severe hypertensive encephalopathy, but may jeopardize the fetus. We recommend antenatal corticosteroids (betamethasone) be given to women with preeclampsia at 26 to 34 weeks of gestation. Magnesium sulfate is more effective than phenytoin for prevention of eclamptic seizures.
