“Although the authors acknowledge that cognitive deterioration following surgery is a common phenomenon, there is little evidence that anesthesia itself or other surgical and patient factors can cause or accelerate cognitive decline and AD. The existing controversy in the field between animal and human studies highlights the need for transitioning from population-based studies to high-quality clinical studies especially with regards to dementia.” (Tsolaki)
“Postoperative neurocognitive decline is a meaningful concern to patients and represents a significant and expanding challenge to health care in the US and worldwide. Surgeons and anesthesiologists should assess, discuss, and optimize associated potential risks for each patient before surgery. Best practices and interventions can begin before surgery and extend well into the recovery period. To be most effective, these strategies require family engagement and the involvement of an interdisciplinary health care team and comprehensive systems of care.” (Vacas)
“Atrial fibrillation, the most common sustained dysrhythmia, is a common postoperative complication. Previous studies have shown that the incidence, prevalence, and associated morbidity and mortality increase progressively with age.
Development of POAF and mortality is dependent upon a wide range of factors not limited to age and medical comorbidities. Although a patient may be at an increased risk for POAF this does not mean they are at an increased risk for mortality.”
This week’s discussion included risk scoring and management of postoperative pancreatic fistula.

Prediction: “Biochemical markers of POP after pancreatic resection are evident from the first postoperative day. These include serum amylase and lipase, and urinary trypsinogen-2. In an observational study of 61 patients undergoing pancreatic resection, the presence of POP on the first postoperative day as determined by these markers was found to be a strong predictor of the development of POPF (OR 17.81, 95% CI 2.17–145.9) [128]
“Despite the medications commonly used in anesthesia allow recovery in a few minutes, a delay in waking up from anesthesia, called delayed emergence, may occur. This phenomenon is associated with delays in the operating room, and an overall increase in costs. Together with the emergence delirium, the phenomenon represents a manifestation of
inadequate emergence. Nevertheless, in delayed emergence, the transition from unconsciousness to complete wakefulness usually occurs along a normal trajectory, although slowed down. On the other hand, this awakening trajectory could proceed abnormally, possibly culminating in the manifestation of emergence delirium. Clinically, delayed emergence often represents a challenge for clinicians who must make an accurate diagnosis of the underlying cause to quickly establish appropriate therapy.”
“Management of interventional radiology catheters has received much less attention in the literature than the techniques of catheter placement. However, this aspect of patient care by interventional radiologists is vitally important in avoiding catheter-related problems.”
“Forty-eight percent of VTEs after ventral hernia repair occur after discharge, particularly in older, male, obese patients undergoing longer and complex operations that require hospitalization > 1 day. Post-discharge thromboprophylaxis should be considered in these patients, particularly when risk of VTE exceeds 0.3%.”
