Vasoplegic Syndrome

AbstractPerioperative hypotension is a well-recognized and relatively common problem during surgery. Vasoplegic syndrome is one such condition which is characterized by severe persistent hypotension with normal to high cardiac output and low systemic resistance. It is commonly seen in patients undergoing cardiac surgery on cardiopulmonary bypass. However, this syndrome has also been reported in off pump surgeries. Management of intraoperative hypotension may be challenging for an anaesthesiologist, if it does not respond or poorly respond to conventional therapy. We report the management of a hypertensive patient posted for spine surgery in prone position, who developed severe hypotension under anaesthesia refractory to treatment.

Vasoplegic Syndrome

Abstract Background Post-cardiotomy vasoplegic syndrome is a vasodilatory shock characterized by a decrease of vascular tone with a normal or increased cardiac output. A relative deficit in vasopressin secretion in the postoperative was hypothesized. Copeptin is secreted in equimolar ratio with vasopressin but it is more stable and easier to measure. The aim of the present study was to investigate whether perioperative copeptin was associated with post-cardiotomy vasoplegic syndrome. Methods All patients scheduled for cardiac surgery were evaluated. Exclusion criteria were age < 18 years old, corticosteroids therapy, heart transplantation, extra-circulatory life support, sepsis, preoperative use of vasoactive drugs, off-pump surgery, chronic hepatic and renal failure, paraneoplastic syndrome, lack of informed consent. Post-cardiotomy vasoplegic syndrome was defined as a mean arterial pressure < 60 mmHg, a reduction of systemic vascular resistances < 1200 dyn*s/cm 5 *m 2 and/or the need of nor-epinephrine ³ 0.1 µg/kg/min. All patients underwent a preoperative evaluation of the corticotropin stimulation test; then, before surgery (T0), on day one after surgery (T1) and after 7 days (T2) copeptin and NT-proBNP concentration were measured. Results Among 55 enrolled patients, 9 (16.3%) developed post-cardiac surgery vasoplegia. Patients with vasoplegia had higher preoperative level of copeptin (19.2 pmol/L, IQR 17.89 – 21.29 vs 11.39 pmol/L, IQR 6.33 - 14.78; p < 0.001) and NT-proBNP (1435 pg/ml, IQR 721.75 – 1836.25 vs 365.5 pg/ml, IQR 141 - 977); p = 0.006) compared to the control group. At the multivariable analysis, preoperative copeptin resulted a significant predictor of vasoplegia (OR 1.56, 95% CI 1.002-1.33) and the ROC analysis showed an accurate copeptin cut off able to identify vasoplegic patients (> 16.9 pmol/L, AUC = 0.86, 95% CI 0.73-0.94). Otherwise, a lack of response to the low dose corticotropin test was not a predictor of PCVS; no patient presented a pathological response to the standard dose test. ConclusionsIncreased preoperative copeptin and NT-proBNP levels might be associated with an increased risk to develop post-cardiotomy vasoplegic syndrome. Our results suggest that patients with a decompensated neuroendocrine control of cardiovascular function are more prone to develop postoperative vasoplegia.

Noninferiority Trial

Abstract Background The detrimental effects of inotropes are well-known, and in many fields they are only used within a goal-directed therapy approach. Nevertheless, standard management in many centers includes administering inotropes to all patients undergoing cardiac surgery to prevent low cardiac output syndrome and its implications. Randomized evidence in favor of a patient-tailored, inotrope-sparing approach is still lacking. We designed a randomized controlled noninferiority trial in patients undergoing cardiac surgery with normal ejection fraction to assess whether an dobutamine-sparing strategy (in which the use of dobutamine was guided by hemodynamic evidence of low cardiac output associated with signs of inadequate tissue perfusion) was noninferior to an inotrope-to-all strategy (in which all patients received dobutamine). Results A total of 160 patients were randomized to the dobutamine-sparing strategy (80 patients) or to the dobutamine-to-all approach (80 patients). The primary composite endpoint of 30-day mortality or occurrence of major cardiovascular complications (arrhythmias, acute myocardial infarction, low cardiac output syndrome and stroke or transient ischemic attack) occurred in 25/80 (31%) patients of the dobutamine-sparing group (p = 0.74) and 27/80 (34%) of the dobutamine-to-all group. There were no significant differences between groups regarding the incidence of acute kidney injury, prolonged mechanical ventilation, intensive care unit or hospital length of stay. Discussion Although it is common practice in many centers to administer inotropes to all patients undergoing cardiac surgery, a dobutamine-sparing strategy did not result in an increase of mortality or occurrence of major cardiovascular events when compared to a dobutamine-to-all strategy. Further research is needed to assess if reducing the administration of inotropes can improve outcomes in cardiac surgery. Trial registration ClinicalTrials.gov, NCT02361801.

AbstractCardiovascular disease (CVD) is a major cause for a significant proportion of all deaths and disability worldwide. Postoperative renal dysfunction following cardiac surgery is not an uncommon complication of cardiac surgery, which has serious implications with regard to morbidity, mortality, financial expenditure, and resource utilization. This study was performed to compare outcomes of patients with preoperative renal dysfunction with those having normal renal function undergoing off-pump coronary artery bypass grafting (OPCABG). Patients were divided into two categories, depending on their preoperative serum creatinine and glomerular filtration rate (GFR). The preoperative renal dysfunction was defined as serum creatinine >1.3 mg/dL and/or estimated GFR (eGFR) of <60 mL/min/1.73 m2. The category A patients had normal renal function defined as serum creatinine ≤1.3 mg/dL and/or eGFR of ≥60 mL/min/1.73 m2 while the category B patients had preoperative renal dysfunction that did not necessitate renal dialysis. Blood samples were collected from both category patients for serum creatinine prior to surgery, following surgery, on postoperative days 1, 2, 3, 4, 5, and on the day of discharge. The occurrence of acute kidney injury (AKI) was defined as an increase in the serum creatinine levels of ≥0.3 mg/dL within 48 hours or an increase of ≥1.5 above baseline known or presumed to have occurred within the previous 7 days based on Kidney Disease Improving Global Outcomes criteria. This study demonstrated that there was worsening of renal function in 7.4% of patients with normal renal function and 10.74% of patients with renal dysfunction that was not statistically different. Based on the results, we conclude that preoperative renal dysfunction may be a contributing predictor of AKI following OPCABG, and we recommend that the patients with more severe renal dysfunction with eGFR of 45–60 mL/min should be studied to demonstrate this hypothesis.
