[The role of magnesium sulfate in providing hemodynamic stability in patients undergoing laparoscopic surgery: a prospective randomized controlled study].

Introduction: during laparoscopic surgery, carbon dioxide (CO) insufflation to create pneumoperitoneum increases blood pressure, heart rate and systemic vascular resistance. The purpose of our study was to investigate the efficacy of magnesium sulfate in preventing adverse hemodynamic reactions associated with pneumoperitoneum in patients undergoing laparoscopic cholecystectomy.

Methods: we conducted a prospective, randomized, double-blind, controlled clinical study of patients scheduled for laparoscopic cholecystectomy and divided into two equal groups: the Mg group received slow intravenous magnesium sulfate 50 mg/kg injection prior to pneumoperitoneum insufflation while the S group received the same volume of 0.

[Posterior reversible encephalopathy syndrome in patients with preeclampsia: case report].

Reversible posterior encephalopathy syndrome (PRES) is a rare clinico-radiological syndrome. Diagnosis is suspected in pregnant women suffering from eclampsia when brain CT scan shows radiological images suggestive of this disease. We here report the case of a 25-year-old pregnant woman at 33 weeks' gestation with a history of pre-eclampsia presenting with convulsive seizures and high blood pressure following cesarean section.
