The SOLAR trial, which compared a composite outcomes in perioperative colorectal or orthopaedic patients, assigned to Lactated Ringers’ (similar to Hartmann’s) solution – over 2 week blocks over a few years (8,616), has been published this month in Anesthesiology. The median volume of fluid administered in the perioperative period was 1.9L, and, no surprise here … Continue reading
It is now more than 5 years since the Anesthesia Patient Safety Foundation highlighted the risk of central nervous system injury following anesthesia for shoulder surgery (SS) in the Beachchair position (BCP) (click here). Although we can never be certain, it appears likely that such injuries – principally devastating stroke, results from hypoperfusion and watershed ischaemia. … Continue reading

Twenty years ago perioperative myocardial ischaemia was a relatively easy thing to diagnose – we checked ECG looking for ST segment and T wave changes, and looked for an MB-CK rise. Then troponin arrived, and suddenly the proportion of patients with perioperative ischaemia increased drastically. For many of us, the report of a “postoperative troponin … Continue reading
Anecdotally, the majority of anesthetists withhold ACE inhibitors (angiotensin converting enzyme inhibitors ACEI) on the day of surgery because of concerns regarding hypotension, particularly in operations that may involve sympathectomy (spinal anesthesia) or blood loss. This appears to be a particular problem with angiotensin receptor blockers (here). We already know that withholding beta blockers and … Continue reading
Over the next few months I am sure that the real reasons for the comparatively poor outcomes of Irish patients in the EUSOS study will emerge. In the meantime, we can only guess the reasons. Aside from blaming surgeons for poor patient selection (which is suspiciously convenient), case volume may be a problem, the time … Continue reading
For years I have been trotting around the world telling everyone that NaCl 0.9% is evil, because each litre delivers 50mmol of HCL and chloride is nephrotoxic. This belief has come from a series of studies in volunteers (reduced GFR, reduced splanchnic perfusion, reduced cortical blood flow) and observations (increased contrast nephropathy with NaCl versus … Continue reading
As a junior doctor how many times were you called to replace an iv catheter on a veinless patient because with was 3 days old (and “hospital policy” and all that). There was no point asking to see the evidence on which this “policy” was based. Whatever! – here is the counter evidence, and it … Continue reading
A 78 year old female patient is brought to the operating room with a fractured hip. She tells you that she wants to “go asleep” for the operation. How do you advise her? Two papers in July’s Anesthesiology have shed light on this issue. Both studies mine large databases and so care must be taken … Continue reading
Colloid lovers are distraught by the publication of the 6S study from Scandanavia, which has demonstrated that hydroxy ethyl starches (HES) were associated with poor outcomes (read here). For many of us, however, colloids are like nicotine, caffeine, carbohydrates and heroin rolled into one: we just believe in them. It’s so hard to stop. This month … Continue reading
