It is unclear if avoiding hyperglycemia during intensive care after acute brain injury improves morbidity, mortality, and neurologic outcome. This prospective randomized trial tested whether intensive insulin therapy affected infection rates, vasospasm, mortality, or long-term neurologic outcome in subarachnoid hemorrhage patients during their intensive care unit (ICU) stay. Comparison was made against conventional insulin therapy using a randomized trial design. The primary outcome measure was infection rate until the fourteenth postoperative day in the ICU or until patient discharge. Secondary end points were the incidence of vasospasm until the fourteenth postoperative day in the ICU or until patient discharge, and neurologic outcome and mortality at 6 months follow-up. A total of 78 patients were prospectively enrolled and randomly assigned either to conventional insulin therapy or to intensive insulin therapy (38 and 40 patients, respectively). The infection rate during the study was significantly higher in patients who received conventional insulin therapy than in patients who received intensive insulin therapy (42% vs. 27%; P<0.001). The incidence of vasospasm during the study was also similar in conventional and intensive therapy groups (31.5% vs. 27.6% in the conventional and intensive insulin therapy groups; P=0.9). Overall mortality rates at 6 months were similar in the 2 groups (18% vs.15%; P=0.9), as was the neurologic outcome at 6 months [modified Rankin score >3 in 22/38 patients (57.8%) in the conventional therapy group vs. 21/40 patients (52.5%) in the intensive insulin therapy group; P=0.7]. Intensive insulin therapy in patients with acute subarachnoid hemorrhage admitted to a postoperative neurosurgical ICU after surgical clipping of intracranial aneurysms decreases infection rates. The benefit of strict glycemic control on postoperative vasospasm, neurologic outcome, and mortality rates does not seem to be affected by intensive insulin therapy.
Intensive research investigating the relation between the management of glycemia and outcome in patients receiving neurocritical care has underlined the possible benefits and adverse events related to glucose control. Here, we review experimental and clinical studies investigating the effects of hypoglycemia and hyperglycemia on the brain that advance current knowledge on managing glycemia in patients receiving neurocritical care.
IntroductionVisceral artery aneurysms (VAA) are rare, frequently present as a life-threatening emergency and are often fatal.The celiacomesenteric trunk (CMT), a common origin of the celiac trunk (CT) and the superior mesenteric artery (SMA) from abdominal aorta, is quite rare. Aneurysms that involve this celiomesenteric anomaly are even rarer and in the last 32 years have been reported in only 20 cases in the literature.Presentation of caseWe describe a case with 30 mm aneurysm arising from a CMT. In general, an aneurysm that is 20 mm or greater in size is considered to be significant enough to warrant treatment. Abdominal VAA sometimes can be treated with low-invasive procedures: our patient required open surgical repair with the celiac artery replanted on to the aorta.DiscussionThe clinical course was complicated only by an increase of hepatic cytolysis enzymes, and by a low output pancreatic fistula, treated conservatively. The patient was discharged on the fifteenth postoperative day. One month after discharge, imaging revealed a good patency of all reconstructed arteries. In the subsequent 36-month follow-up period, the patient reported no clinical episodes.ConclusionOur finding of a very rare case of a celiomesenteric anomaly with a concurrent aneurysm is extremely rare (20 cases in word literature in the last 32 years). The feasibility of the endovascular approach for aneurysms originating from the common celiomesenteric trunk depends mainly on aneurysmal location, diameter and neck size. In case of specific unfit anatomy, a careful surgical treatment can ensure the best results.
In patients receiving neurocritical care for cerebral edema, the adjunct of a potassium sparing diuretic (canrenone) to mannitol therapy reduces potassium urinary loss, prevents hypokalemia, and reduces the incidence of new cardiac arrhythmias.
