Article Synopsis
- The study investigated the link between cerebral oxygen levels and postoperative delirium in older cardiac surgery patients, finding that while intraoperative oxygen levels weren't significantly tied to delirium, lower postoperative oxygen levels were associated with increased delirium rates.
- Of the 103 patients studied, about 30% experienced delirium, with particularly noticeable drops in oxygen levels among those affected.
- Factors like older age, prior strokes, and certain pre-existing health assessments were independently linked to higher incidences of delirium post-surgery.
Diagnostic error in the Emergency Department: follow up of patients with minor trauma in the outpatient clinic.
Scand J Trauma Resusc Emerg Med

Background: The Emergency Department (ED) is prone to diagnostic error. Most frequent diagnostic errors involved "minor" trauma. Our goal was to determine how frequently a missed diagnosis was detected during follow up and to determine the frequency and causes of primary missed diagnosis and diagnostic error.

Moreover, residual NMB could impair postoperative respiratory function. We tested the hypotheses that deep NMB could improve the quality of surgical conditions for laparoscopic bariatric surgery compared with moderate NMB and investigated whether deep NMB puts patients at risk for postoperative respiratory impairment compared with moderate NMB.

Cerebral oxygenation was measured continuously with Near-Infrared Spectroscopy and compared retrospectively between balloon-expandable, self-expandable and differential deployment valves which were implanted in 12 (34%), 17 (49%) and 6 patients (17%), respectively. Left and right SctO values were averaged at four time points and used for analysis (i.

In addition, the outflow obstruction is often aggravated by an abnormal mitral valve and subvalvular apparatus.
Methods: We performed transatrial myectomy in 12 patients with diffuse hypertrophy, who were highly symptomatic despite maximal medical therapy.
