BACKGROUND Anesthesia without muscle relaxants has been reported to be effective for early extubation after thymectomy, but postoperative respiratory status of the patients has not been studied intensively. METHODS Fifty-two consecutive patients undergoing thymectomies for myasthenia gravis (MG) were evaluated. RESULTS Forty-two (81%) of the 52 patients were extubated in the operating room,...

Effect of Paco,, on Blood Flow and Microvasculature of Ischemic and Nonischemic Cerebral Cortex • The right middle cerebral artery (MCA) was occluded in cats; after subsequent craniectomy cortical blood flow (CBF) was measured bilaterally with Kr, and photographs of the superficial microvasculature were made. Ventilation was controlled, and P a ^ was altered by changing the concentration of C0 ...

Transcriptional repressors provide widespread biological significance in the regulation of gene expression. However, in prokaryotes, it is particularly difficult to find transcriptional repressors that recognize specific target promoters on genome-scale. To address this need, a genetic biosensor for identifying repressors of target promoters was developed in Escherichia coli from a de novo desi...

La revista Casa de las Américas, en su edición enero-febrero 1968, publica un número dedicado al Che Guevara, asesinado octubre del año anterior, Bolivia. Juan Gelman y Francisco Urondo escriben para esta convocatoria: el primero, “Pensamientos”, que publicará luego libro Cólera Buey 1971; segundo, “Descarga”. Ambos poetas se incorporarán finalmente a FAR. Ernesto Guevara “El Socialismo hombre ...

STUDY AIM To evaluate the feasibility of combined oximetry (pulse oximetric saturation [Spo(2)]) and cutaneous capnography (transcutaneous carbon dioxide tension [Ptcco(2)]) for oxygen titration in patients requiring long-term oxygen therapy. METHODS Twenty patients with obstructive or restrictive lung disease underwent oxygen titration using a combined cutaneous oximetry-capnography sensor. ...

Delirium and transient neurologic dysfunctions (TND) often complicate the postoperative course after surgery for acute type-A aortic dissection (AAD). We evaluated the role of clonidine on neurological outcome and respiratory function in 30 consecutive patients undergoing surgery for AAD. Patients were prospectively randomized to receive either clonidine (0.5 microg/kg bolus, followed by contin...

OBJECTIVE To evaluate the association between time on mechanical ventilation and anthropometric, clinical and pulmonary function variables, measured early, in infants on invasive mechanical ventilation with acute respiratory failure due to viral bronchiolitis, and the temporal progression of variables with significant correlations. METHODS Twenty-nine infants admitted to the pediatric intensi...

OBJECTIVE Noninvasive positive pressure ventilation (NIPPV) has been shown to decrease the need for invasive mechanical ventilation (MV) in patients presenting with acute respiratory failure (ARF). We conducted a prospective study to assess if NIPPV use, in a developing country, was associated with clinical and physiological improvements. DESIGN Prospective observational study. MATERIALS AN...
