ICU Renal Replacement and Long term Morbidity

Renal replacement therapy in ICU may predict increased cardiovascular morbidity in the long term compared to those who did not receive it. This Korean study showed a higher major cardiovascular event rate, mortality and rate of end stage renal disease. Where renal replacement has been used in ICU survivors, increased vigilance is needed long term as well as management of risk factors.

Optic nerve sheath diameter and intracranial pressure

There have been a number of studies on the use of ocular ultrasound measurement of optic nerve sheath diameter to non-invasively diagnose raised intracranial pressure. This meta-analysis shows that while it seems to be reasonable, wide confidence intervals suggest caution in its use. It can be employed as an aid certainly, and to dictate further assessment.

Transfusion Related Acute Lung Injury

Restrictive transfusion is today the norm. Transfusion related acute lung injury (TRALI) is reported as the main cause of transfusion related mortality. This study is reassuring in finding “The incidence of TRALI was estimated to be 1 case per 47,000 units of any blood product or 1 case per 20,000 units of plasma”.

It is felt that the HLA related antibodies in plasma are implicated and increasing use of male plasma may play a role in declining rates of TRALI. Given the latest approach to trauma involves early plasma and platelets, or whole blood, the findings are important, albeit a retrospective and single center study.

Local vs. general anaesthesia for carotid endarterectomy

A new review may not ultimately settle the debate on general vs. local anesthesia for carotid endarterectomy. Only in analysis of observational studies showed reduced risk of stroke, TIA, MI and mortality. Randomized trial analysis did not show these benefits. LA decreased shunt insertion which may in itself increased embolic stroke.

All in all they conclude “Although randomised studies have not confirmed any advantage for local anaesthesia, this may be due to a lack of pooled statistical power in these trials”. Nonetheless as the gold standard, further randomized studies may be needed to settle the debate to account for confounding and other variables.

Pre-operative Oral Care and Cancer Surgery Outcome

Oral hygiene may be linked to aspiration of oro-pharyngeal secretions and this study concludes that preoperative oral care by a dentist significantly reduced postoperative complications in patients who underwent cancer surgery.They found reduced pneumonia and even mortality rates. Limitations of the study include its retrospective nature and analysis of an administrative claims database. It clearly deserves further study.
