[Intensive care unit profesionals's knowledge about non invasive ventilation comparative analysis]. / Análisis comparativo de los conocimientos en ventilación mecánica no invasiva de profesionales de cuidados intensivos.

AIMS: The literature highlights the lack of noninvasive ventilation (NIV) protocols and the variability of the knowledge of NIV between intensive care units (ICU) and hospitals, so we want to compare NIV nurses's Knowledge from 4 multipurpose ICU and one surgical ICU. METHODS: Multicenter, crosscutting, descriptive study in three university hospitals. The survey instrument was validated in a pilot test, and the calculated Kappa index was 0.9. Returning a completed survey is an indication of informed consent. Analysis by Chi square test. RESULTS: 117 responded (65%) nurses, 11±9.7 years of experience in ICU and 9.2±7.2 in use of NIV. One of the multipurpose ICU, was initiated NIV an average of 6 years later than the others (95% CI [3.3 to 8.6], P<.001). Only 23.1% of nurses would place a non-vented mask (with no exhalation port) by conventional ventilator, the rest any kind of face mask. 12.7% believed that the mask must be adjusted to the "2-finger" fit while 29% would seal the mask to the patient's face and cover the mask opening where air escapes to facilitate patient/ventilator synchronization. In the surgical ICU agitation identifies mostly as a complication of NIV compared with multipurpose UCIs (31.6% vs 1.8%, P<.001). 56.4% of nurses do not consider respiratory physiotherapy as nursing care, with no difference between units. CONCLUSIONS: Knowledge about types of interface is very dependent on the material of the unit. More training for complications of NIV as agitation and handling secretions it is necessary.

[Retroperitoneal mucinous cystadenocarcinoma presenting seven years after appendectomy and right hemicolectomy]. / Cistoadenocarcinoma mucinoso retroperitoneal ocurrido a los 7 años de apendicectomía y hemicolectomía derecha.

Retroperitoneal mucinous cystadenocarcinoma (RMC) with no involvement of neighboring structures is very rare, regardless of whether the lesion is primary or secondary. We report the case of a patient who presented RMC seven years after appendectomy and right hemicolectomy. We discuss both diagnostic possibilities.

Urgent Multidetector Computed Tomography in Colon Cancer: Postsurgical Changes and Early Complications. / Tomografía computarizada multidetector urgente de la cirugía del cáncer colorrectal: Cambios posquirúrgicos y complicaciones tempranas.

Complications after surgery for colorectal cancer are common in emergency departments. Multidetector computed tomography plays a fundamental role in the follow-up of patients after surgery, because it enables the detection of relapse and complications. Radiologists need to be familiar with different surgical techniques and the normal postsurgical changes so that we can differentiate them from potential complications and relapse. This article reviews the multidetector computed tomography findings that can be considered normal after surgical intervention for colorectal cancer as well as the most common early complications seen in postsurgical colorectal cancer patients presenting at emergency departments.
