Valoración de la tolerancia y seguridad de 5 modelos de sedación durante la realización de la ecobroncoscopia / Tolerance and Safety of 5 Models of Sedation During Endobronchial Ultrasound

Introducción: La sedación durante la ecobroncoscopia es importante debido a la duración prolongada de esta exploración. Evaluamos distintos modelos de sedación y sus complicaciones. Método: Se realizó un estudio multicéntrico, prospectivo y observacional en el que recogieron distintas variables en 307 pacientes con distintos modelos de sedación: a) midazolam en bolo; b)propofol en perfusión; c) midazolam en bolo y propofol en perfusión; d) propofol en perfusión y remifentanilo en perfusión, y e) midazolam en bolo y fentanilo en bolo. Finalizada la prueba, los pacientes contestaron una encuesta de satisfacción. Resultados: Los pacientes por modelo de sedación fueron: A 24, B 37, C 107, D 62 y E 77. Las puntuaciones de las sensaciones percibidas de recuerdo, dolor, tos, disnea y exploración prolongada (0,65 ± 1,11; 0,3 ± 0,73; 0,46 ± 0,9; 0,29 ± 0,73; 0,59 ± 0,96) fueron menores frente a miedo y nerviosismo antes de la exploración (1,26 ± 1,37 y 1,5 ± 1,41). Los valores elevados de indiferencia ante la repetición (1,49 ± 1,3) y de sensación agradable de la prueba (1,23 ± 1,17), junto con cifras bajas la sensación de angustia (0,49 ± 0,85) e incomodidad de la exploración (0,62 ± 1,1), muestran que los distintos modelos de sedación fueron bien tolerados. El 46,6% de los pacientes no encontraron ningún momento malo y el 89,6% se repetiría la prueba. Los modelos E y C fueron los que menos complicaciones presentaron (12,9 y 31,7%) y, en todos los casos, se resolvieron con medidas terapéuticas sencillas. Conclusiones: Los modelos de sedación analizados fueron bien tolerados y la mayoría aceptarían la repetición de la ecobroncoscopia. Las complicaciones fueron escasas y sencillas de resolver

Introduction: Sedation during endobronchial ultrasound (EBUS) is essential due to the long duration of this procedure. We evaluated different models of sedation and their complications. Method: A multicenter, prospective, observational study of 307 patients undergoing EBUS was conducted. Patients were sedated with: a) midazolam bolus; b) propofol infusion; c) midazolam bolus and propofol infusion; d) propofol infusion and remifentanil infusión, or e)midazolam bolus and fentanyl bolus, and clinical variables were collected. Patients were asked to complete a satisfaction survey following the test. Results: Patients per sedation model were: A 24, B 37, C 107, D 62 and E 77. Scores for perceived sensations of recall, pain, cough, dyspnea and prolonged examination (0.65 ± 1.11; 0 3 ± 0.73, 0.46 ± 0.9, 0.29 ± 0.73, and 0.59 ± 0.96, respectively) were lower compared to fear and nervousness before the examination (1.26 ± 1.37 and 1.5 ± 1.41, respectively). High levels of indifference to repeating the procedure (1.49±1.3) and a reported pleasant feeling during the test (1.23±1.17), with low levels of anxiety (0.49 ± 0.85) and discomfort (0.62 ± 1.1), show that different models of sedation were well tolerated. Almost half the patients (46.6%) did not report any "worst momento" during the procedure, and 89.6% were willing to undergo a repeat test. The E and C models presented fewest complications (12.9 and 31.7%, respectively), and all were resolved with simple therapeutic measures. Conclusions: The models of sedation evaluated were well tolerated and most patients were willing to undergo repeat EBUS. Complications were few and easily resolved

Utilización de procalcitonina y proteína C reactiva como marcadores de infección en la neutropenia febril de pacientes sometidos a trasplante de progenitores hematopoyéticos / Use of procalcitonin and C-reactive protein as infection markers in febrile neutropenic patients undergoing haematopoietic stem cell transplant

INTRODUCCIÓN Y OBJETIVO: La neutropenia es un signo frecuente en los pacientes que van a ser sometidos a trasplante de progenitores hematopoyéticos (TPH). Una complicación importante es la infección favorecida por la inmunodepresión y el grado de neutropenia. El objetivo del estudio es evaluar la utilidad diagnóstica de la procalcitonina (PCT) y de la proteína C reactiva (PCR) en pacientes onco-hematológicos sometidos a quimioterapia y TPH para discriminar la etiología de la fiebre. PACIENTES Y MÉTODOS: Se midieron los valores de PCT y PCR en 30 episodios de neutropenia febril antes del inicio de la quimioterapia, el día de la neutropenia, el día del inicio de la fiebre y los días 1, 2, 3 y 6 postinicio de la fiebre y al fin del episodio. Los episodios fueron clasificados como 5 bacteriemias, 3 infecciones documentadas microbiológicamente, 10 infecciones clínicas y 12 fiebres de origen desconocido. RESULTADOS: Los valores medios de PCT más elevados correspondieron al grupo de pacientes con bacteriemia. Hubo diferencias estadísticamente significativas (p = 0,04) el segundo día tras el inicio de la fiebre. El punto de corte de 0,5 ng/ml mostró una sensibilidad del 66% y una especificidad del 75%. La PCR mostró diferencias estadísticamente significativas los días 1, 2 y 3 postinicio de la fiebre (p = 0,01; p = 0,003 y p = 0,002). El punto de corte de 7,5 mg/dl mostró una sensibilidad del 88% y una especificidad del 58%. CONCLUSIONES: La combinación de PCT y PCR es un método insuficiente para la detección de infección bacteriana y no puede sustituir el correcto diagnóstico clínico y microbiológico

INTRODUCTION AND OBJECTIVE: Neutropenia is a frequent sign in patients who are going to have a haematopoietic stem cell transplant (HSCT).Infection is an important complication in these patients, which is favoured by immunosuppression and the degree of neutropenia. This study aims to evaluate the diagnostic usefulness of procalcitonin (PCT) and C-reactive protein (CRP) in onco-haematological patients undergoing chemotherapy and HSCT to determine the origin of the fever. PATIENTS AND METHODS:PCT and CRP values were measured in 30 episodes of febrile neutropenia: before starting chemotherapy, appearance of neutropenia, onset of fever, days 1, 2, 3 and 6 after the onset of fever, and when the febrile episode ended. The episodes were classified as 5 bacteraemia, 3 microbiologically documented infections, 10 clinical infections, and 12 fevers of unknown origin. RESULTS: The highest PCT mean values corresponded to the group of patients with bacteraemia. Statistically significant differences (P=.04) were found on the second day after the onset of fever. The cut-off point of 0.5ng/ml showed a sensitivity of 66% and a specificity of 75%. PCR results showed statistically significant differences on days 1, 2 and 3 after the onset of fever (P=.01, P=.003, and P=.002, respectively). The cut-off point of 7.5mg/L had a sensitivity of 88% and a specificity of 58%.CONCLUSIONS:The combination of PCT and CRP is an insufficient method to detect bacterial infections and may not replace the proper clinical and microbiological diagnosis (AU)

HE4, Ca125 and ROMA algorithm for differential diagnosis between benign gynaecological diseases and ovarian cancer.

The aim of this study is to evaluate the diagnostic performance of human epididymis protein 4 (HE4), cancer antigen 125 (Ca125) and the risk of ovarian malignancy algorithm (ROMA) in discriminating ovarian cancer from other benign gynaecological diseases. Serum levels of HE4 and Ca125 were measured in 119 women with benign gynaecological diseases, 29 patients with primary ovarian cancer, 32 patients with ovarian cancer on chemotherapy treatment (18 of them with progressive disease), 6 patients treated and free of disease and 32 healthy women. Sensitivity, specificity, positive and negative predictive values and positive and negative likelihood ratios (LR ±) were calculated. Receiver operator characteristic (ROC) curves were constructed, and the areas under the curve (AUC) were calculated. High serum levels for HE4, Ca125 and ROMA were observed in cancer patients. HE4 was elevated in 12.6 %, Ca125 in 21 % and ROMA in 9.2 % in the benign group, but HE4 was not elevated in endometriosis. The AUC values for HE4, Ca125 and ROMA were 0.92, 0.911 and 0.945 respectively. The sensitivity for discriminating ovarian cancer from benign gynaecological diseases was 86.2 % for HE4 and Ca125 and 93.1 % for ROMA. The specificity was 87.4, 78.9 and 90.7 % for HE4, Ca125 and ROMA. The overall positive likelihood ratio (LR+) was 6.84 for HE4, 4.1 for Ca125 and 10.01 for ROMA. In premenopausal women, LR + was 11.86 for HE4, 5.11 for ROMA and 2.02 for Ca125. HE4 might be significant in the differential diagnosis of ovarian cancer. HE4 seems to be superior to Ca125 in terms of diagnostic performance of all premenopausal women. ROMA could help to discriminate in cases with any doubt with a high diagnostic accuracy.
