Post-operative delirium(POD) is common in older adults and is characterized by changes in attention and cognition. Objective: To determine the preoperative risk factors associated with POD in adults submitted to balanced general anesthesia at Hospital Metropolitano Angeles. material and methods: Cross-sectional study. Fifty adults aged 60 years or older were included in the Confusion Assessment Method (CAM) at the time of admission to the recovery room. A logistic regression model was used to fi the associated risk factors. results: A total of 50 patients with a mean age of 70.8 (± 7.1) years were included. By sex 60.0% (30) were women and 40.0% (20) men. Patients underwent gastrointestinal-abdominal surgeries (34%), orthopedic (26%), urologic (16%), cardiovascular (12%) and others (12%). DPO was detected in 22 (44.0%) patients, not fi signifi differences by age and sex. The variables associated with POD were surgery duration (OR = 1.04 [95% CI 1.01-1.06, p = 0.004]) and the presence of elevated intraoperative glucose levels (OR = 1.02 [95% CI 1.00-1.04, p = 0.049]). Conclusions: POD is a frequent complication in the elderly, so it is necessary to provide timely diagnosis and implementation of prevention strategies for this population. [ABSTRACT FROM AUTHOR]

Introduction: Venous thrombosis is a pathology of difficult or misleading clinical diagnosis, for that in approximately 70-80% of the patients that suffer from said illness; its existence is not suspected. The radiologist is usually the first doctor that suggests the thrombosis diagnosis in any topography based on the imaging findings and to the capacity of MDCT Objective: To know the incidence and to demonstrate the characteristics through MDCT of venous thrombotic lesions. Material and methods: A prospective study of February 2005 to August 2007 was carried out, of those cases remitted to MDCT for several reasons, including abdominal pain of origin to be determined, patients with cancer background and handling pursuit as well as post-surgery status and in those that incidentally, abdominopelvic venous thrombosis was demonstrated. 3,500 studies carried out with 8 and 16 MDCT equipment were included, with abdominopelvic conventional protocol that included simple initial and post-contrast IV, stages, as well as arterial, venous and excreting stages with sagital/coronary PMR. Results: 76 patients -2% of the total of studies carried out in the study - (37 male, 39 female, age ranges 15 to 96 years) were identified, to those a study was carried out according to protocol for the following clinical conditions (67%); abdominal pain of origin to determine in 11 (20%), patients with cancer background and handling pursuit in 24 (44%), by search of primary in six (11%), post-surgical status in seven (13%), with hepatopathy in study in six (11%) and in those that incidentally abdominopelvic venous thrombosis was demonstrated. In 22 patients (29%), abdominopelvic venous thrombosis was demonstrated without sufferings pointed out in their clinical records, or, well-known previous to the study like thrombosis-condition. Conclusions: Triphasic MDCT is the elected study for the identification and valuation of thrombosis of any topography and of the pathology that originates it, overcoming the evaluation carried out by US Doppler in the diagnosis of thrombosis, when specifying the location and extension of the thrombus. The timely diagnosis of thrombosis and of its etiology, justifies the employment of further radiation doses thoroughly for a thriphasic study. [ABSTRACT FROM AUTHOR]
