Actualización en anemia y terapia transfusional / Anemia and transfusion therapy: an update

La anemia representa una de las patologías más prevalentes en la población general y constituye una entidad extremadamente frecuente en pacientes médicos y quirúrgicos de todas las especialidades. Una correcta valoración de su impacto y de las posibilidades terapéuticas resulta crucial. La transfusión de sangre alogénica representa una medida eficaz en el manejo de la anemia, pero no está exenta de importantes complicaciones. Es responsabilidad del clínico conocer y sopesar todas las alternativas disponibles para el manejo global de la anemia. Transfusiones sanguíneas, agentes estimuladores de la eritropoyesis, ferroterapia (oral y endovenosa) y otras alternativas terapéuticas han de ser empleadas de forma racional y ajustándonos a la evidencia clínica disponible hasta la fecha. El presente artículo de revisión resume algunas características epidemiológicas de la anemia, su valoración clínica y las principales alternativas terapéuticas a la luz de los conocimientos actuales, con especial énfasis en el paciente crítico (AU)

Anemia is one of the most prevalent diseases in the general population and is a very frequently found condition in medical and surgical patients in all medical specialties. A good evaluation of its clinical impact and its therapeutic possibilities is essential. Allogenic blood transfusion is a useful procedure in anemia management, although it has important adverse effects. It is the responsibility of the clinician to know and to take into account all the available alternatives for the treatment of anemia. Blood transfusions, erythropoiesis-stimulating agents, iron therapy (oral and endovenous) and other therapeutic alternatives must be rationally used, in accordance with the currently available clinical evidence. This review article summarizes some epidemiological characteristics of anemia, its clinical evaluation and the main therapeutic possibilities based on the present knowledge, placing special emphasis on the critically ill patient (AU)

A double-blind, placebo-controlled trial of ciprofloxacin prophylaxis in patients with acute necrotizing pancreatitis.

BACKGROUND: The use of prophylactic antibiotics in acute severe necrotizing pancreatitis is controversial. METHODS: Prospective, randomized, placebo-controlled, double-blind study was carried out at Bellvitge Hospital, in Barcelona, Spain. Among 229 diagnosed with severe acute pancreatitis, 80 had evidence of necrotizing pancreatitis (34/80 patients were excluded of the protocol). Forty-six patients without previous antibiotic treatment with pancreatic necrosis in a contrast-enhanced CT scan were randomly assigned to receive either intravenous ciprofloxacin or placebo. Five patients were secondarily excluded, and the remaining 41 patients were finally included in the study (22 patients received intravenous ciprofloxacin and 19 patients placebo). RESULTS: Comparing the 22 with intravenous ciprofloxacin and 19 with placebo, infected pancreatic necrosis was detected in 36% and 42% respectively (p = 0.7). The mortality rate was 18% and 11%, respectively (p = 0.6). No significant differences between both treatment groups were observed with respect to variables such as: non-pancreatic infections, surgical treatment, timing and the re-operation rate, organ failure, length of hospital and ICU stays. CONCLUSION: The prophylactic use of ciprofloxacin in patients with severe necrotizing pancreatitis did not significantly reduce the risk of developing pancreatic infection or decrease the mortality rate. The small number of patients included in this study should be considered.

Laparoscopic adrenalectomy. A review of 30 initial cases.

BACKGROUND: Laparoscopic adrenalectomy is a good option for removal of the adrenal gland that is becoming preferred over the conventional open technique. METHODS: We reviewed the initial 30 laparoscopic adrenalectomies (in 27 patients) that were performed at our institution from 1995 to 1998. We used the lateral decubitus transperitoneal approach in 26 cases and the retroperitoneal approach in only one case. The indications for adrenalectomy were Conn's adenoma in eight patients, pheochromocytoma in six, Cushing's syndrome in five, nonfunctional adenomas in seven, and metastasis in one case. RESULTS: Only two patients (7%) were converted to laparotomy. Operating time ranged from 75 to 240 min. Average adrenal gland size was 6.1 cm (range, 4-9 cm). There was no mortality, and morbidity occurred in only two patients (8%)-one case of self-limited gastrointestinal bleeding and one case of hypercapnia and subcutaneous emphysema (in the only patient operated by the retroperitonal approach). Mean hospital stay was 3 days (range, 1-6). CONCLUSIONS: Laparoscopic adrenalectomy is a safe and useful procedure for nearly all adrenal pathologies. Lateral decubitus transperitoneal approach is the procedure of choice in most cases.
