RESUMO
Background: To investigate the impact of Cryo Nerve Block with cryoICE™ device utilization, on post-operative pain in patients undergoing isolated coronary artery bypass grafting (CABG) through left thoracotomy. Methods: All consecutive patients undergoing isolated CABG through left thoracotomy between July 2021 and July 2022 from a single surgeon were included in the study. Patients using the cryoICE™ device for nerve block were compared for baseline demographics and pre-operative characteristics with those that did not use the cryoICE™ device. A propensity-adjusted analysis was used to compare the two groups. The primary outcome was degree of incisional pain and numbness. Results: A total of 103 patients underwent isolated CABG through left thoracotomy. After matching, the cryoICE™ device was used for nerve block in 60 patients while the control group included 43 patients. Mean follow-up was 5.7 months. The cryoICE™ device group had a mean value of incisional pain at hospital discharge was 1.5 (scale 0-10) while at follow-up was 0.69 (scale 0-10). Mean values of skin numbness at hospital discharge were 1 (scale 0-10) and 0.57 (scale 0-10) at follow-up. After univariate analysis comparison of cryoICE™ device group (60 patients) versus non-cryoICE™ device group (43 patients), the total in-hospital morphine use was 49% lower in the cryoICE™ versus the non-cryoICE™ cohort (73.8 + 79.37 mg vs 144.1 + 118.99 mg). Conclusions: Good clinical outcomes were observed in patients undergoing isolated left thoracotomy CABG with cryoICE™ utilization, including a very low incidence of post-operative pain, numbness, and hypersensitivity for all comers.
RESUMO
BACKGROUND AND AIM OF THE STUDY: Although abundant biological, clinical, and scientific evidence exists on the superiority of multi-arterial (MAR) and total-arterial revascularization (TAR) over the conventional strategy with a single internal thoracic artery, only 10% of patients undergoing coronary artery bypass grafting (CABG) in the United States receives a second arterial conduit, and only 5% of patients receives TAR. METHODS AND RESULTS: In January 2020, the authors performed comprehensive search to identify studies that evaluated MAR and TAR strategies through the MEDLINE database. CONCLUSIONS: In this paper, the authors reviewed the literature on the historical and current evidence in favor of MAR and TAR, thus underlying why current CABG practice needs qualitative improvement.

Methylene blue (MB) has received much attention in the perioperative and critical care literature because of its ability to antagonize the profound vasodilation seen in distributive (also referred to as vasodilatory or vasoplegic) shock states. This review will discuss the pharmacologic properties of MB and review the critical care, liver transplantation, and cardiac anesthesia literature with respect to the efficacy and safety of MB for the treatment of shock. Although improved blood pressure has consistently been demonstrated with the use of MB in small trials and case reports, better oxygen delivery or decreased mortality with MB use has not been demonstrated. Large randomized controlled trials are still necessary to identify the role of MB in hemodynamic resuscitation of the critically ill.

OBJECTIVES: The Total Artificial Heart (Syncardia, Tucson, AZ) is approved for use as a bridge-to-transplant or destination therapy in patients who have irreversible end-stage biventricular heart failure. We present a unique case, in which the inferior vena cava compression by a total artificial heart was initially masked for days by the concurrent placement of an extracorporeal membrane oxygenation cannula. PATIENT: This is the case of a 33-year-old man admitted to our institution with recurrent episodes of ventricular tachycardia requiring emergent total artificial heart and venovenous extracorporeal membrane oxygenation placement. CONCLUSION: This interesting scenario highlights the importance for critical care physicians to have an understanding of exact anatomical localization of a total artificial heart, extracorporeal membrane oxygenation, and their potential interactions. In total artificial heart patients with hemodynamic compromise or reduced device filling, consideration should always be given to venous inflow compression, particularly in those with smaller body surface area. Transesophageal echocardiogram is a readily available diagnostic tool that must be considered standard of care, not only in the operating room but also in the ICU, when dealing with this complex subpopulation of cardiac patients.

OBJECTIVE: The aim of this study was to determine the effect of pulmonary artery catheterization on clinical outcomes after cardiac surgery in higher-risk patients. DESIGN: Retrospective national database analysis. SETTING: U.S. hospitals. PARTICIPANTS: A weighted sample of 2,063,337 patients undergoing cardiac surgery identified from the Nationwide Inpatient Sample (NIS) from January 1, 2000 to December 31, 2010. INTERVENTIONS: Pulmonary artery catheterization. MEASUREMENTS AND MAIN RESULTS: Compared to patients who did not receive a pulmonary artery catheter, those who did on the whole were on average slightly older (66.6±11.9 years v 65.5±12.8 years, p<0.001), more likely to have pulmonary hypertension (7.5% v 5.1%, p<0.001), chronic obstructive pulmonary disease (24.6% v 20.7%, p<0.001), obesity (15.0% v 13.1%, p<0.001), and chronic renal failure (10.9% v 9.2%, p<0.001). In multivariate analysis, the risk of operative mortality in patients who underwent pulmonary artery catheterization was significantly higher than in those who did not (4.6% v 3.1%, p<0.001), adjusted OR 1.34 (95% CI 1.26-1.43, p<0.001). In propensity matched subgroup analysis operative mortality risk was higher in octogenarian patients (OR 1.24, p = 0.24), and patients with congestive heart failure (OR 1.39, p = 0.023) who underwent pulmonary artery catheterization. No significant difference in operative mortality was observed in low-risk patients according to whether or not they underwent pulmonary artery catheterization. The incidence of prolonged mechanical ventilation and length of stay>30 days was higher in patients who underwent pulmonary artery catheterization in all subgroups. CONCLUSIONS: In contemporary practice pulmonary artery catheters do not appear to be associated with reductions in operative mortality or morbidity and are associated with increases in duration of ventilation and length of stay in the intensive care unit.

OBJECTIVES: The objective of this study was to evaluate the impact of timing of tracheostomy on outcomes of patients with respiratory failure after cardiac surgery. DESIGN: Retrospective analysis of national database. SETTING: United States hospitals. PARTICIPANTS: A weighted estimate of 2,063,227 patients (475,773 case records) undergoing cardiac surgery identified from the Nationwide Inpatient Sample between 2002-2010 INTERVENTIONS: Early versus late tracheostomy. MEASUREMENTS AND MAIN RESULTS: The incidence of postoperative respiratory failure was 7.8%. The strongest independent predictors of respiratory failure included female gender (odds ratio [OR] 1.3, 95% confidence interval [CI] 1.28-1.31), age (OR 1.13 for each decade, 95% CI 1.12-1.13), chronic obstructive airways disease (OR 2.16, 95% CI 2.13-2.19), chronic renal insufficiency (OR 2.28, 95% CI 2.25-2.31), and valve surgery (OR 1.62, 95% CI 1.6-1.64). Tracheostomy was performed in 22.9% of patients with respiratory failure; 13.6% of tracheostomies were performed within 5 days of surgery (or within 5 days of intubation in patients who underwent reintubation), and 20.5% were performed on postoperative day 21 or later. Compared with tracheostomy performed within 5 days of intubation, there was a near-stepwise increase in risk of mortality with delayed tracheostomy performed between days 11-15 (OR 1.29, 95% CI 1.16-1.43), days 16-20 (OR 1.25, 95% CI 1.11-1.41), and day 21 or later (OR 1.53, 95% CI 1.37-1.71). CONCLUSIONS: In this analysis of outcomes of patients with respiratory failure after cardiac surgery in the United States, deferring tracheostomy did not appear to improve patient outcomes after cardiac surgery.

OBJECTIVE: This study sought to identify periprocedural risk predictors that affect long-term prognosis in patients with chronic obstructive pulmonary disease (COPD) undergoing isolated coronary artery bypass grafting (CABG). METHODS: All consecutive 4,871 patients undergoing isolated CABG between May 2005 and June 2021 were included. Patients with and without COPD were compared for baseline demographics and preoperative characteristics. A propensity-matched analysis was used to compare the 2 groups. The primary outcome was long-term incidence of all-cause death. RESULTS: After matching, 767 patients each were included in the COPD and non-COPD groups; mean age was 71.6 and 71.4 years (P = .7), respectively; 29.3% and 32% (P = .2) were women, respectively. Intraoperatively, median (IQR) operating room time was higher in the COPD group than in the non-COPD group (5.9 [5.2-7.0] hours vs 5.8 [5.1-6.7] hours, respectively; P = .01). Postoperatively, intensive care unit stay (P = .03), hospital length of stay (P = .0004), and fresh frozen plasma transfusion units (P = .012) were higher in the COPD group than in the non-COPD group. Thirty-day mortality was not different between groups (1.3% in the COPD group vs 1% in the non-COPD group; P = .4). Median follow-up time was 4.0 years. The rate of all-cause death was higher in the COPD group than in the non-COPD group (138 patients [18.3%] vs 109 patients [14.5%], respectively; P = .042). Periprocedural risk predictors for all-cause death in patients with COPD were atrial fibrillation, diabetes, male sex, dialysis, ejection fraction less than 50%, peripheral vascular disease, and Society of Thoracic Surgeons Predicted Risk of Mortality score greater than 4%. CONCLUSION: Patients with COPD undergoing isolated CABG had a significantly higher incidence of all-cause death than those without COPD. Herein, risk predictors are provided for all-cause death in patients undergoing isolated CABG.

OBJECTIVES: The aim of this study was to compare long-term prognosis after isolated coronary artery bypass grafting between white and black patients and to investigate risk factors for poorer outcomes among the latest. METHODS: All consecutive 4766 black and white patients undergoing isolated coronary artery bypass grafting between May 2005 and June 2021 at our institution were included. Primary outcomes were long-term incidence of all-cause death and major adverse cardiovascular and cerebrovascular events in black versus white patients. A propensity-matched analysis was used 2 compare groups. RESULTS: After matching, 459 patients were included in each black and white groups while groups were correctly balanced. The mean age was 70.4 vs 70.6 years old (P = 0.7) in black and white groups, respectively. Intraoperatively, mean operating room time and blood product transfusion, were higher in the black group while incidence of extubation in the operating room was higher in the white one. Postoperatively, hospital length of stay was higher in the black cohort. Thirty-day all-cause mortality was not different among groups. The median follow-up time was 4 years. Primary outcome of all-cause death was higher in the black versus the white, respectively. Major adverse cardiovascular and cerebrovascular events incidence was twice higher in the black compared to the white cohort (7.6% vs 3.7%, P = 0.013). Risk predictors for all-cause death and major adverse cardiovascular and cerebrovascular events in blacks were creatinine level, chronic obstructive pulmonary disease, ejection fraction <50% and preoperative atrial fibrillation. CONCLUSIONS: Racial disparities persist in a high-volume centre. Despite no preoperative difference, black minority has a higher incidence of major adverse cardiovascular and cerebrovascular events.
RESUMO
OBJECTIVES: The purpose of this study was to investigate whether patients who received methylene blue as treatment for vasoplegia during cardiac surgery with cardiopulmonary bypass had decreased morbidity and mortality. DESIGN: Retrospective analysis. SETTING: Single tertiary care university hospital. PARTICIPANTS: Adult patients who suffered from vasoplegia and underwent all types of cardiac surgery with cardiopulmonary bypass at this institution between 2007 and 2008. INTERVENTIONS: With IRB approval, the authors reviewed the charts of the identified patients and divided them into 2 groups based on whether they had received methylene blue. Two hundred twenty-six patients were identified who met the inclusion criteria for the study. Fifty-seven of these patients had received methylene blue for vasoplegia. The authors collected data on preoperative and intraoperative variables as well as outcomes. MEASUREMENTS AND MAIN RESULTS: The patients who received methylene blue had higher rates of in-hospital mortality, a compilation of morbidities, as well as renal failure and hyperbilirubinemia. A multiple logistic regression model demonstrated that receiving methylene blue was an independent predictor of in-hospital mortality (p value: 0.007, OR 4.26, 95% CI: 1.49-12.12), compilation of morbidities (p value: 0.001, OR 4.80, 95% CI: 1.85-12.43), and hyperbilirubinemia (p value:<0.001, OR 6.58, 95% CI: 2.91-14.89). Using propensity score matching, the association with morbidity was again seen but the association with mortality was not found. CONCLUSIONS: The current study identified the use of methylene blue as treatment for vasoplegia to be independently associated with poor outcomes. While further studies are required, a thorough risk-benefit analysis should be applied before using methylene blue and, perhaps, it should be relegated to rescue use and not as first-line therapy.

In this article, we focus on the important role of robot-assisted coronary surgery by reporting the successful case of a morbidly obese male (body mass index = 58 kg/m2) who presented to our center with severe coronary disease. A 54-year-old morbidly obese male presented with acute chest pain and was diagnosed with coronary artery disease. The culprit lesion was the left anterior descending (LAD) coronary artery. A percutaneous coronary intervention angiography attempted in a university hospital was not successful. Our heart team chose a hybrid robot-assisted revascularization (HCR) strategy based on the patient's body size. The patient underwent left internal thoracic mammary artery to LAD bypass with uneventful postoperative recovery. Robotic HCR is a valuable strategy in morbidly obese patients undergoing coronary artery bypass grafting.

Nitrous oxide (N2O) is an anesthetic and analgesic gas with a long history of medical applications. It acts on multiple supraspinal and spinal targets and has utility in a wide range of clinical situations. The relative safety, low incidence, and acuity of adverse effects of N2O, along with the ability to be administered by trained medical providers with varying clinical backgrounds, as well as self-administered by patients, assure its persistent and expanding role in clinical practice.

BACKGROUND: Chronic kidney disease (CKD) is associated with a high prevalence of atrial fibrillation (AF), but in this population the risk/benefit ratio of anticoagulant therapy with vitamin K antagonists (VKA) for thromboprophylaxis is uncertain. SUMMARY: In end-stage renal disease (ESRD) patients undergoing hemodialysis, VKA seem less effective in stroke prevention than in the general population, with an increased risk of major bleeding. Recently, novel oral anticoagulant agents (NOACs) have proven to be effective for stroke prevention in AF and have demonstrated an improved safety profile compared to VKA. Limited data from post hoc analyses of controlled clinical trials suggest the safe and effective use of NOACs in patients with moderate renal impairment (i.e., estimated glomerular filtration rate, eGFR, between 30 and 50 mL/min). The question still remains whether NOACs can be used in patients with an eGFR <30 mL/min, since there are no studies addressing this subject. In fact, patients with CKD stage 4 and 5 were excluded from controlled clinical trials on anticoagulation therapy for stroke prevention in AF. Left atrial appendage (LAA) occlusion represents a nonpharmacological alternative for stroke prevention in patients with AF who are difficult to manage medically. Preliminary data indicate a similar efficacy and safety profile in patients with CKD compared to patients with normal renal function. KEY MESSAGES: Stroke prevention in patients with ESRD and AF represents a clinical challenge with poor evidence. LAA occlusion may become the standard of care for stroke prevention in patients with ESRD and AF.
RESUMO
Mechanical circulatory support devices have been increasingly used for long-term support. We reviewed outcomes in all patients supported with a SynCardia total artificial heart (TAH) for more than 1 year to assess its safety in long-term support. As of December 2011, all 47 patients who received the TAH from 10 centers worldwide were included in this retrospective study. Clinical data were collected on survival, infections, thromboembolic and hemorrhagic events, device failures, and antithrombotic therapy. The mean age of patients was 50 ± 1.57 years, the median support time was 554 days (range 365-1373 days). The primary diagnosis was dilated cardiomiopathy in 23 patients, ischemic in 15, and "other" in 9. After a minimum of 1 year of support, 34 patients (72%) were successfully transplanted, 12 patients (24%) died while on device support, and 1 patient (2%) is still supported. Five patients (10%) had a device failure reported. Major complications were as follows: systemic infections in 25 patients (53%), driveline infections in 13 patients (27%), thromboembolic events in 9 patients (19%), and hemorrhagic events in 7 patients (14%). SynCardia TAH has proven to be a reliable and effective device in replacing the entire heart. In patients who reached a minimum of 1 year of support, device failure rate is acceptable and only in two cases was the leading cause of death. Infections and hemorrhagic events were the major causes of death. Patients who remain supported beyond 1 year are still likely to survive to transplantation.
