Atención de las emergencias y urgencias médico-quirúrgicas en un hospital oncológico / Emergencies and urgent medical-surgical conditions attended at a comprehensive cancer center

La incidencia global de las emergencias y urgencias médicoquirúrgicas en pacientes con cáncer ha sido descrita esporádicamente. El objetivo del estudio fue identificar los principales síntomas y diagnósticos de los pacientes que acudieron al Servicio de Urgencias del Hospital de Oncología, Centro Médico Nacional Siglo XXI, Instituto Mexicano del Seguro Social. El diseño fue observacional y retrospectivo. La información fue obtenida del registro de la consulta diaria del Servicio de Admisión Continua. En un periodo de seis meses fueron atendidos 4,937 pacientes. Los cuadros clínicos evaluados como emergencias correspondieron a 3.7 %, como condiciones médicas urgentes 52.5 % y como condiciones no urgentes, 43.7 %. Los síntomas más frecuentes motivo de las consultas de emergencia o urgencias en los pacientes con cáncer fueron dolor grave en 69.5 % y deshidratación con desequilibrio hidroelectrolítico en 11.4 %. Los principales síntomas fueron provocados por el tumor primario o su diseminación metastásica, en 89 %. Los tumores malignos sólidos más frecuentes fueron los carcinomas mamario, de colon/recto, cervicouterino, broncogénico y gástrico. Las principales emergencias registradas en los pacientes con cáncer en este estudio fueron choque séptico y neutropenia severa (20 %), choque hipovolémico por sangrado en diversos sitios (16.5 %) y disnea agudizada por neumonía o derrame pleural (12 %). En aproximadamente 80 % de quienes son tratados paso a paso de manera racional, el dolor por cáncer pudo ser controlado sólo con analgésicos. La analgesia no efectiva se asoció frecuentemente con prescripción inadecuada o ingesta insuficiente de analgésicos opioides. Los servicios de urgencias establecidos funcionalmente en los hospitales monográficos de cáncer ofrecen la mejor oportunidad de tratamiento a los pacientes con cáncer con condiciones emergentes o urgentes.

The global incidence of emergencies and urgent medical?surgical conditions in cancer patients has not been well described. The aim of the study was to identify the main symptoms and diagnoses in patients seen for consultation at the Urgent Care Service in a Mexican Comprehensive Cancer Center. This was a retrospective observational study. The information was obtained from the Continuous Admission Service daily consultation records at the Oncology Hospital, National Medical Center 21st Century, Institute of Social Security, Mexico City. During a 6-month period, 4937 patients were seen for consultation. True oncologic emergencies were 3.7%, urgencies 52.5% and non-urgent were 43.7%. Most common symptoms for emergency and urgency patient consultations were severe pain (69.5%) and dehydration with electrolyte imbalance (11.4%). Prevalent symptoms were associated with the primary tumor or metastatic dissemination (89% cases). The most frequent baseline diseases were breast, colorectal, cervical, lung and stomach carcinomas. Defined oncologic emergencies in this series were septic shock and severe neutropenia (20%), hypovolemic shock due to severe bleeding (16.5%), and severe dyspnea due to pneumonia or pleural efusion (12%). Data evaluating the use of analgesic drug therapy for cancer pain alone indicate that 80% of patients report adequate analgesia. Analgesia failures were associated with an insufficient prescription or with inadequate consumption of opioid analgesics. The Urgent Care Center at a Comprehensive Cancer Center offers the best opportunity for diagnosis and treatment of emergencies and urgent care conditions in cancer patients.
