Rapid and homogeneous reperfusion as a risk factor for postreperfusion syndrome during orthotopic liver transplantation.
The revascularization of the graft remains as a crucial instant of the orthotopic liver transplantation (OLT) surgical procedure. About a third of the recipients suffer the postreperfusion syndrome (PRS), a combination of hypothermia, metabolic disorders and cardiovascular instability potentially leading to cardiac arrest. The objective of this study was to evaluate the speed-quality (SQR) of the graft;s reperfusion as an independent predictor of PRS. ⋯ According to our results, SQR can be considered an unambiguous predictor of PRS.

Comparative StudyHemodynamic effects of atracurium and cisatracurium and the use of diphenhydramine and cimetidine.
Since atracurium can cause hypotension in humans, the hemodynamic effects of atracurium and cisatracurium as well as the hemodynamic protection of diphenhydramine and cimetidine were investigated in rats. ⋯ The isolated administration of diphenhydramine and cimetidine did not prevent the reduction in mean arterial pressure induced by atracurium. However, the association of both drugs was able to prevent the hemodynamic effects of atracurium. The doses of cisatracurium used in this study did not cause a reduction in blood pressure significant enough to justify the use of the preventive measures used in the atracurium groups.

Randomized Controlled Trial Comparative StudyDisposable versus reusable laryngeal tube suction for ventilation in patients undergoing laparoscopic cholecystectomy.
The laryngeal tube suction II (LTS-II) is a recent version of reusable supraglottic airway devices allowing gastric drainage. In this prospective, randomized study we compared insertion and ventilation of disposable LTS-II (LTS-D) with reusable type (LTS-II) for airway management under conditions with elevated intra abdominal pressure induced by capnoperitoneum. ⋯ Both devices provide a secure airway under conditions of elevated intra abdominal pressure.

ReviewApplications of magnesium sulfate in obstetrics and anesthesia.
Magnesium is predominantly an intracellular ion. Its blocking effects on NMDA receptors are responsible for the analgesic and sedative characteristics of this ion. The objective of this study was to review the physiology, pharmacology, and decreased plasma levels of magnesium, as well as its applications in obstetrics and anesthesia. ⋯ Magnesium sulfate has been used in obstetrics with good results, inhibiting premature labor and in the treatment of eclampsia-associated seizures. It is potentially analgesic and sedative, and could be used as adjuvant during general anesthesia, attenuating the blood pressure response to tracheal intubation and decreasing the need of anesthetics.
