[Effects of low doses of aprotinin in heart surgery].

OBJECTIVES: To study the effect of aprotinin (Trasylol) administration on bleeding after surgery and on the need for blood transfusion in patients undergoing cardiopulmonary bypass with extracorporeal circulation (ECC). PATIENTS AND METHODS: One hundred ten patients were studied prospectively, divided into two groups. In the aprotinin group (n = 80), the ECC pump was primed with 140 mg of aprotinin and followed with continuous intravenous perfusion at 70 mg/h from the start of ECC until the patient left the operating theater. The control group (n = 30) served as reference. The parameters compared were the hematocrit, number of platelets, prothrombin time and activated coagulation time, as well as drainage of blood through thoracic tubes at 3 and 24 h after surgery and the amount of blood transfused both during and after the procedure. RESULTS: Blood loss was significantly lower in the aprotinin group as compared with the control group, both at 3 h (227 +/- 193 vs 380 +/- 169 ml; p < 0.05) and at 24 h (422 +/- 322 ml vs 736 +/- 342 ml; p < 0.05) after surgery. There was also a significant decrease in blood requirements in the aprotinin group (550 +/- 450 ml vs 872 +/- 747 ml; p < 0.05). There were no differences between the two groups for the other parameters studied. CONCLUSIONS: Administration of aprotinin at low doses during surgery in patients undergoing cardiac surgery with ECC significantly reduces postoperative bleeding and the amount of blood transfused.

[Mortality by poisoning in children].

OBJECTIVE: To determine the standing of mortality by poisoning in children in the Mexican Republic, in the years from 1979-1994. MATERIAL AND METHODS: Secondary sources were employed. Analyzed variables were: age, sex, year, external cause of trauma and poisoning according to the 9th International Classification of Diseases: E850-E858, E860-E869 and E905. Tendencies by specific causes were analyzed with a Poisson regression model and relative risk by age, sex and district were obtained. RESULTS: A total of 11,272 children under 15 years of age were recorded. The main causes were poisoning and toxic reactions caused by venomous plants or animals (E905); accidental poisoning by household gas or carbon monoxide (E868); and accidental poisoning by other drugs (E858). The relative risk was highest in age group < 1 year; the values were RR 29.6, CI 95% 29.2-33.4; RR 3.47, CI 95% 2.86-4.22 and RR 31.86, CI 95% 24.8-40.9. Risk was similar for both sexes except for E905. The state of Aguascalientes consistently presented the highest risk values and the state of Nuevo Leon, the lowest. CONCLUSIONS: Poisoning is an important cause of child mortality. Considering that most of these deaths can potentially be prevented since they occur at home it is recommended that responsible adults can build protection into their environment and into the way society operates. Prevention should involve a multidisciplinary approach since the phenomenon has multiple causes and possible solutions.
