Abstract Background: Inotropes used to obtain short-term hemodynamic benefits in cardiac surgery may carry a risk of increased myocardial ischemia and adverse outcomes. This study investigated the association between intra- and postoperative use of inotropes and mortality and postoperative complications. Methods: A historic cohort study using prospective data from the Western Denmark Heart Registry on 6,005 consecutive cardiac surgery cases from three university hospitals. Propensity matching on pre- and intraoperative variables was used to identify a subgroup of patients receiving inotropic therapy (n = 1,170) versus comparable nonreceivers (n = 1,170) for outcome analysis. Results: Two thousand ninety-seven patients (35%) received inotropic therapy; 3,908 (65%) did not receive any inotropic or vasopressor support perioperatively. Among propensity-matched cohort including 2,340 patients 30-day mortality was 3.2% and 1-yr mortality was 7.6%. In the matched cohort, patients exposed to inotropes had a higher 30-day mortality (adjusted hazards ratio, 3.7; 95% CI, 2.1 to 6.5) as well as a higher 1-yr mortality rate (adjusted hazards ratio, 2.5; 95% CI, 1.8 to 3.5) compared with nonreceivers. Among propensity-matched, the following absolute events rates were observed: myocardial infarction 2.4%, stroke 2.8%, arrhythmia 35%, and renal replacement therapy 23.9%. Inotropic therapy was independently associated with postoperative myocardial infarction (adjusted odds ratio, 2.1; 95% CI, 1.4 to 3.0), stroke (adjusted odds ratio, 2.4; 95% CI, 1.4 to 4.3), and renal replacement therapy (adjusted odds ratio, 7.9; 95% CI, 3.8 to 16.4). Conclusion: Use of intra- and postoperative inotropes was associated with increased mortality and major postoperative morbidity.

The Impact

Abstract Background Acute kidney injury (AKI) is a frequent and deadly complication after cardiac surgery. In the absence of effective therapies, a focus on risk factor identification and modification has been the mainstay of management. The authors sought to determine the impact of intraoperative hypotension on de novo postoperative renal replacement therapy in patients undergoing cardiac surgery, hypothesizing that prolonged periods of hypotension during and after cardiopulmonary bypass (CPB) were associated with an increased risk of renal replacement therapy. Methods Included in this single-center retrospective cohort study were adult patients who underwent cardiac surgery requiring CPB between November 2009 and April 2015. Excluded were patients who were dialysis dependent, underwent thoracic aorta or off-pump procedures, or died before receiving renal replacement therapy. Degrees of hypotension were defined by mean arterial pressure (MAP) as less than 55, 55 to 64, and 65 to 74 mmHg before, during, and after CPB. The primary outcome was de novo renal replacement therapy. Results Of 6,523 patient records, 336 (5.2%) required new postoperative renal replacement therapy. Each 10-min epoch of MAP less than 55 mmHg post-CPB was associated with an adjusted odds ratio of 1.13 (95% CI, 1.05 to 1.23; P = 0.002), and each 10-min epoch of MAP between 55 and 64 mmHg post-CPB was associated with an adjusted odds ratio of 1.12 (95% CI, 1.06 to 1.18; P = 0.0001) for renal replacement therapy. The authors did not observe an association between hypotension before and during CPB with renal replacement therapy. Conclusions MAP less than 65 mmHg for 10 min or more post-CPB is associated with an increased risk of de novo postoperative renal replacement therapy. The association between intraoperative hypotension and AKI was weaker in comparison to factors such as renal insufficiency, heart failure, obesity, anemia, complex or emergent surgery, and new-onset postoperative atrial fibrillation. Nonetheless, post-CPB hypotension is a potentially easier modifiable risk factor that warrants further investigation.

Abstract Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background The multicenter randomized Colloids versus Crystalloids for the Resuscitation of the Critically Ill (CRISTAL) trial was designed to test whether colloids altered mortality compared to crystalloids in the resuscitation of intensive care unit patients with hypovolemic shock. This preplanned analysis tested the same hypothesis in the subgroup of surgical patients. Methods The CRISTAL trial prospectively defined patients as critically ill surgical patients whenever they underwent emergency or scheduled surgery immediately before or within 24 h of intensive care unit admission and had hypovolemic shock. The primary outcome measure was death by day 28. Secondary outcome measures included death by day 90, the need for renal replacement therapy, or the need for fresh frozen plasma transfusion. Results There were 741 critically ill surgical patients, 356 and 385 in the crystalloid and colloid arm, respectively. Median (interquartile range) age was 66 (52 to 76) yr, and 484 (65.3%) patients were male. Surgery was unscheduled in 543 (73.3%) cases. Mortality by day 28 did not significantly differ for crystalloids 84 (23.6%) versus colloids 100 (26%; adjusted odds ratio, 0.86; 95% CI, 0.61 to 1.21; P = 0.768). Death by day 90 (111 [31.2%] vs. 122 [31.7%]; adjusted odds ratio, 0.97; 95% CI, 0.70 to 1.33; P = 0.919) did not significantly differ between groups. Renal replacement therapy was required for 42 (11.8%) patients in the crystalloids arm versus 49 (12.7%) in the colloids arm (P = 0.871). Conclusions The authors found no survival benefit when comparing crystalloids to colloids in critically ill surgical patients.

AbstractObjectives:To characterise the mortality and neurological outcomes of paediatric cardiac patients requiring cardiopulmonary resuscitation for more than 30 minutes prior to extracorporeal membrane oxygenation cannulation and to identify risk factors associated with adverse outcomes in this population.Materials and methods:Observational retrospective cohort study in paediatric cardiac patients undergoing cardiopulmonary resuscitation for greater than 30 minutes prior to cannulation in a tertiary children’s hospital, from July 2000 to July 2013.Results:Seventy-three paediatric cardiac patients requiring cardiopulmonary resuscitation for more than 30 minutes prior to cannulation were included in the study. Survival to hospital discharge was 43.8%, with 75% of survivors having either normal neurologic function or only mild disability. Multivariable logistic regression analysis demonstrated that increased use of calcium during resuscitation (odds ratio 14.5, p 0.01), cardiopulmonary resuscitation duration >50 minutes (odds ratio 4.12, p 0.03), >6 interruptions of chest compressions during cannulation (odds ratio 6.40, p 0.03), the need for continuous renal replacement therapy (odds ratio 11.1, p 0.001), and abnormal pupillary response during extracorporeal membrane oxygenation (odds ratio 33.9, p 0.006) were independent predictors for hospital mortality.Conclusion:Survival after cardiopulmonary resuscitation for more than 30 minutes prior to extracorporeal membrane oxygenation cannulation in our paediatric cardiac cohort was 43.8%. Factors associated with mortality included calcium use during resuscitation, longer cardiopulmonary resuscitation, increased chest compression pauses during cannulation, the use of continuous renal replacement therapy, and abnormal pupils during extracorporeal membrane oxygenation support. A prospective assessment of these factors in paediatric cardiac patients may be beneficial in improving outcomes.

<strong>Background:</strong> Acute kidney injury is a common complication of cardiac surgery that increases morbidity and mortality. The aim of the present study is to analyze the association of preoperative serum albumin levels with acute kidney injury and the requirement of renal replacement therapy after isolated coronary artery bypass graft surgery (CABG).<br /><strong>Methods:</strong> We retrospectively reviewed the prospectively collected data of 530 adult patients who underwent isolated CABG surgery with normal renal function. The perioperative clinical data of the patients included demographic data, laboratory data, length of stay, in-hospital complications and mortality. The patient population was divided into two groups: group I patients with preoperative serum albumin levels &lt;3.5 mg/dL; and group II pateints with preoperative serum albumin levels ≥3.5 mg/dL.<br /><strong>Results:</strong> There were 413 patients in group I and 117 patients in group II. Postoperative acute kidney injury (AKI) occured in 33 patients (28.2%) in group I and in 79 patients (19.1%) in group II. Renal replacement therapy was required in 17 patients (3.2%) (8 patients from group I; 9 patients from group II; P = .018). 30-day mortality occurred in 18 patients (3.4%) (10 patients from group I; 8 patients from group II; P = .037). Fourteen of these patients required renal replacement therapy. Logistic regression analysis revealing the presence of lower serum albumin levels preoperatively was shown to be associated with increased incidence of postoperative AKI (OR: 1.661; 95% CI: 1.037-2.661; <br />P = .035). Logistic regression analysis also revealed that DM (OR: 3.325; 95% CI: 2.162-5.114; P = .000) was another independent risk factor for AKI after isolated CABG. <br /><strong>Conclusion:</strong> Low preoperative serum albumin levels result in severe acute kidney injury and increase the rate of renal replacement therapy and mortality after isolated CABG.

Maori Health

Māori are the indigenous people of New Zealand, and suffer disparate health outcomes compared to non-Māori. Waikato District Health Board provides level III intensive care unit services to New Zealand’s Midland region. In 2016, our institution formalised a corporate strategy to eliminate health inequities for Māori. Our study aimed to describe Māori health outcomes in our intensive care unit and identify inequities. We performed a retrospective audit of prospectively entered data in the Australian and New Zealand Intensive Care Society database for all general intensive care unit admissions over 15 years of age to Waikato Hospital from 2014 to 2018 ( n = 3009). Primary outcomes were in–intensive care unit and in-hospital mortality. The secondary outcome was one-year mortality. In our study, Māori were over-represented relative to the general population. Compared to non-Māori, Māori patients were younger (51 versus 61 years, P < 0.001), and were more likely to reside outside of the Waikato region (37.2% versus 28.0%, P < 0.001) and in areas of higher deprivation ( P < 0.001). Māori had higher admission rates for trauma and sepsis ( P < 0.001 overall) and required more renal replacement therapy ( P < 0.001). There was no difference in crude and adjusted mortality in–intensive care unit (16.8% versus 16.5%, P = 0.853; adjusted odds ratio 0.98 (95% confidence interval 0.68 to 1.40)) or in-hospital (23.7% versus 25.7%, P = 0.269; adjusted odds ratio 0.84 (95% confidence interval 0.60 to 1.18)). One-year mortality was similar (26.1% versus 27.1%, P=0.6823). Our study found significant ethnic inequity in the intensive care unit for Māori, who require more renal replacement therapy and are over-represented in admissions, especially for trauma and sepsis. These findings suggest upstream factors increasing Māori risk for critical illness. There was no difference in mortality outcomes.

Objective: Procalcitonin (PCT) has been associated with adverse outcomes after cardiac surgery. Nevertheless, there is no consensus on thresholds and timing of PCT measurement to predict adverse outcomes. Materials & methods: A total of 960 patients undergoing elective cardiac surgery were retrospectively evaluated. PCT levels were measured from the first to the seventh postoperative day (POD). The onset of complications was recorded. Results: Complications occurred in 421 (44%) patients. PCT on the third POD was associated with the occurrence of any kind of complications (odds ratio: 1.06; p: 0.037), and noninfectious complications (odds ratio: 1.05; p: 0.035), after adjusting. PCT above the median value at the third POD (>0.33 μg/l) predicted postoperative complications (incidence rate ratio: 1.13; p = 0.035). Conclusion: PCT seems to predict postoperative complications in cardiac surgery. The determination at the third POD yields the greatest sensitivity and specificity.

Background: Due to increased risks of contrast nephropathy, chronic kidney disease (CKD) can deter consideration of invasive management for patients with myocardial infarction (MI). Black patients have a higher prevalence of CKD. Whether racial disparities exist in the use of invasive MI management for patients with CKD presenting with MI is unknown. Methods: We examined 717 012 White and 99 882 Black patients with MI treated from 2008 to 2017 at 914 hospitals in the National Cardiovascular Data Registry Chest Pain—MI Registry. CKD status was defined as estimated glomerular filtration rate (eGFR) ≥90 mL/(min·1.73 m 2 ; no CKD), eGFR <90 but ≥60 (mild), eGFR <60 but ≥30 (moderate), and eGFR <30 or dialysis (severe). We used multivariable logistic regression models to examine the interaction of race and CKD severity in invasive MI management. Results: Among those with MI, Black patients were more likely than White patients to have CKD (eGFR <90; 61.4% versus 58.5%; P <0.001). Among those with MI and CKD, Black patients were more likely than White patients to have severe CKD (21.2% versus 12.4%; P <0.001). Patients with CKD were more likely than those without CKD to have diabetes or heart failure; Black patients with CKD were more likely to have these comorbidities when compared with White patients with CKD (all P <0.0001). Black race and CKD were associated with a lower likelihood of invasive management (adjusted odds ratio, 0.78 [95% CI, 0.75–0.81]; adjusted odds ratio, 0.72 [95% CI, 0.70–0.74]; P <0.001 for both). At eGFR levels ≥10, Black patients were significantly less likely than White patients to undergo invasive management. Conclusions: Black patients with MI and mild or moderate CKD were less likely to undergo invasive management compared with White patients with similar CKD severity. National efforts are needed to address racial disparities that may remain in the invasive management of MI.
