    Anesthesia for electroconvulsive therapy: clinical experience
    (Wiley, 2007) González, Aridane G.; Cortínez, Luis I.; Cuadra F., Juan Carlos de la; Carrasco, Elena; Rioseco, Alonso; Léniz, Pamela Wisnia
    OBJECTIVE: To assess the utility of propofol and succinylcholine in obtaining optimal convulsions and assuring patient safety during electroconvulsive therapy. PATIENTS AND METHODS: This was a prospective observational study of patients undergoing electroconvulsive therapy under general anesthesia with propofol and succinylcholine. We recorded patient characteristics, doses of propofol and succinylcholine, electroencephalographically-recorded duration of convulsions, and complications. Descriptive statistics were compiled and the data were subjected to analysis of correlations, comparison with the Student t test for independent samples, the Mann-Whitney U test, and analysis of variance. RESULTS: We studied 108 patients, 62% women and 38% men, 80% classified as ASA 1 and 20% as ASA 2. The patients underwent 844 sessions of electroconvulsive therapy; their mean (SD) age was 39.95 (18.09) years. The doses of propofol and succinylcholine were 1.34 (0.32) mgxkg(-1) and 1.35 (0.26) mgxkg(-1), respectively. The mean recorded duration of the first convulsion (29.87 [22.42] seconds) was negatively correlated with age (r = -0.12) and unrelated to propofol dose (r = 0.06) or body weight (r = 0.02). Male and schizophrenic patients had longer-lasting convulsions (P < .01). Cardiovascular complications occurred in 2.4% and psychomotor agitation in 1.4%; there were no respiratory complications, musculoskeletal injuries, nausea, or vomiting. CONCLUSIONS: Electroconvulsive therapy can be safely applied in an operating room or similar space undergeneral anesthesia and with a neuromuscular blockade in order to prevent psychological or musculoskeletal trauma. Propofol did not affect the convulsions at the dosages administered.

    Effects of a dairy product fortified with multiple micronutrients and omega-3 fatty acids on birth weight and gestation duration in pregnant Chilean women
    (CAMBRIDGE UNIV PRESS, 2008) Mardones, Francisco; Urrutia, Maria Teresa; Villarroel, Luis; Rioseco, Alonso; Castillo, Oscar; Rozowski, Jaime; Tapia, Jose Luis; Bastias, Gabriel; Bacallao, Jorge; Rojas, Ivan
    objective: To test the hypothesis that maternal food fortification with omega-3 fatty acids and multiple micronutrients increases birth weight and gestation duration, as primary outcomes.
