To investigate whether a single dosage of esketamine injection in the anesthesia period could improve postoperative negative emotions and early cognitive function in patients undergoing non-cardiac thoracic surgery. A prospective single center double blinded randomized placebo-controlled trial. Perioperative period; operating room, post anesthesia care unit and hospital ward. 129 adult patients that underwent elective non-cardiac thoracic surgery under general anesthesia. During the operation, pharmacologic prevention of postoperative negative emotion and early cognitive disorder with 0.2 mg/kg (Low esketamine group) and 0.5 mg/kg esketamine (High esketamine group) vs. placebo. Emotion and early cognitive performance were assessed on the day before surgery (POD-1), postoperative day 1 (POD1) and day 3 (POD3) using HADS-A, HADS-D, Pain Visual Analogue Scale (VAS), Confusion Assessment Method (CAM), Mini-Mental State Examination (MMSE), and serum biomarkers (S100β, BDNF, IL-6, acetylcholine, and norepinephrine). The high esketamine group showed significantly lower HADS-A and HADS-D scores than control group on POD1 and POD3. No significant differences were observed between the low esketamine group and the control group. The esketamine-treated groups showed lower pain VAS scores than the control group at 2 h and on the first day after operation. There were no significant differences among the three groups in CAM and MMSE scores. However, the high esketamine group had lower S100β and IL-6 levels, and higher BDNF levels postoperatively, while serum acetylcholine and norepinephrine were not significantly different. A single intraoperative injection of 0.5 mg/kg esketamine can alleviate postoperative anxiety, depression, and pain to some extent. Although cognitive function behavioral evaluation did not show obvious benefits, it can also reduce the production of pro-inflammatory and brain injury-related factors while promoting the generation of brain-derived neurotrophic factor. Registration Trial registry: http://www.chictr.org.cn/; Identifier: ChiCTR2100047067. •Intraoperative injection of 0.5 mg/kg of esketamine relieves postoperative anxiety, depression, and pain in thoracic surgery.•0.5 mg/kg of esketamine reduces inflamation, brain injury factors, and boosts BDNF.•0.2 mg/kg esketamine somewhat relieves post-op pain, not anxiety or depression.•Esketamine used in this study did not show an obvious benefit on postoperative cognitive assessment.

BackgroundThe effect of two lung ventilation (TLV) with carbon dioxide artificial pneumothorax on cerebral desaturation and postoperative neurocognitive changes in elderly patients undergoing elective minimally invasive esophagectomy (MIE) is unclear.ObjectivesThe first aim of this study was to compare the effect of TLV and one lung ventilation (OLV) on cerebral desaturation. The second aim was to assess changes in early postoperative cognitive outcomes of two ventilation methods.MethodsThis prospective, randomized, controlled trial enrolled patients 65 and older scheduled for MIE. Patients were randomly assigned (1:1) to TLV group or OLV group. The primary outcome was the incidence of cerebral desaturation events (CDE). Secondary outcomes were the cumulative area under the curve of desaturation for decreases in regional cerebral oxygen saturation (rSO2) values below 20% relative to the baseline value (AUC.20) and the incidence of delayed neurocognitive recovery.ResultsFifty-six patients were recruited between November 2019 and August 2020. TLV group had a lower incidence of CDE than OLV group [3 (10.71%) vs. 13 (48.14%), P = 0.002]. TLV group had a lower AUC.20 [0 (0–35.86) % min vs. 0 (0–0) % min, P = 0.007], and the incidence of delayed neurocognitive recovery [2 (7.4%) vs. 11 (40.7%), P = 0.009] than OLV group. Predictors of delayed neurocognitive recovery on postoperative day 7 were age (OR 1.676, 95% CI 1.122 to 2.505, P = 0.006) and AUC.20 (OR 1.059, 95% CI 1.025 to 1.094, P < 0.001).ConclusionCompared to OLV, TLV had a lower incidence of CDE and delayed neurocognitive recovery in elderly patients undergoing MIE. The method of TLV combined with carbon dioxide artificial pneumothorax may be an option for these elderly patients.Chinese Clinical Trial Registry (identifier: ChiCTR1900027454).

Adults undergoing cardiac surgery with cardiopulmonary bypass received either an intravenous balanced mixture of amino acids or placebo for up to 3 days. Amino acids reduced the occurrence of acute kidney injury.

Background. Cardiac allograft vasculopathy (CAV) remains the Achilles’ heel of long-term survival after heart transplantation (HTx). The severity and extent of CAV is graded with conventional coronary angiography (COR) which has several limitations. Recently, vessel fractional flow reserve (vFFR) derived from COR has emerged as a diagnostic computational tool to quantify the functional severity of coronary artery disease. Purpose. The present study assessed the usefulness of vFFR to detect CAV in HTx recipients. Methods. In HTx patients referred for annual check-up, undergoing surveillance COR, the extent of CAV was graded according to the criteria proposed by the international society of heart and lung transplantation (ISHLT). In addition, three-dimensional coronary geometries were constructed from COR to calculate pressure losses using vFFR. Results. In 65 HTx patients with a mean age of 53.7 ± 10.1 years, 8.5 years (IQR 1.90, 15.2) years after HTx, a total number of 173 vessels (59 LAD, 61 LCX, and 53 RCA) were analyzed. The mean vFFR was 0.84 ± 0.15 and median was 0.88 (IQR 0.79, 0.94). A vFFR ≤ 0.80 was present in 24 patients (48 vessels). HTx patients with a history of ischemic cardiomyopathy (ICMP) had numerically lower vFFR as compared to those with non-ICMP (0.70 ± 0.22 vs. 0.79 ± 0.13, p=0.06). The use of vFFR reclassified 31.9% of patients compared to the anatomical ISHLT criteria. Despite a CAV score of 0, a pathological vFFR ≤ 0.80 was detected in 8 patients (34.8%). Conclusion. The impairment in epicardial conductance assessed by vFFR in a subgroup of patients without CAV according to standard ISHLT criteria suggests the presence of a diffuse vasculopathy undetectable by conventional angiography. Therefore, we speculate that vFFR may be useful in risk stratification after HTx.

In a randomized trial, 5243 patients undergoing cardiac surgery were assigned to a restrictive or a liberal red-cell transfusion threshold. The restrictive threshold was noninferior to the liberal one for the composite outcome of death, myocardial infarction, stroke, or renal failure.

A randomized trial evaluating spinal as compared with general anesthesia for hip-fracture surgery in adults 50 years of age or older did not show superiority of spinal anesthesia with respect to a composite of death or an inability to walk unassisted at 60 days. Postoperative delirium occurred in similar percentages of patients in the two groups.

Delirium is a common postoperative complication in elderly patients which has a serious impact on outcome in terms of morbidity and costs. We examined whether a postoperative multi-factorial intervention program can reduce delirium and improve outcome in patients with femoral neck fractures. One hundred and ninety-nine patients, aged 70 years and over (mean age+/-SD, 82+/-6, 74% women), were randomly assigned to postoperative care in a specialized geriatric ward or a conventional orthopedic ward. The intervention consisted of staff education focusing on the assessment, prevention and treatment of delirium and associated complications. The staff worked as a team, applying comprehensive geriatric assessment, management and rehabilitation. Patients were assessed using the Mini Mental State Examination and the Organic Brain Syndrome Scale, and delirium was diagnosed according to DSM-IV criteria. The number of days of postoperative delirium among intervention patients was fewer (5.0+/-7.1 days vs 10.2+/-13.3 days, p=0.009) compared with controls. A lower proportion of intervention patients were delirious postoperatively than controls (56/102, 54.9% vs 73/97, 75.3%, p=0.003). Eighteen percent in the intervention ward and 52% of controls were delirious after the seventh postoperative day (p<0.001). Intervention patients suffered from fewer complications, such as decubitus ulcers, urinary tract infections, nutritional complications, sleeping problems and falls, than controls. Total postoperative hospitalization was shorter in the intervention ward (28.0+/-17.9 days vs 38.0+/-40.6 days, p=0.028). Patients with postoperative delirium can be successfully treated, resulting in fewer days of delirium, fewer other complications, and shorter length of hospitalization.

In a trial of TAVR in patients with a small aortic annulus, a self-expanding valve was noninferior to a balloon-expandable valve for clinical outcomes and was superior for bioprosthetic-valve dysfunction through 12 months.

A previous analysis in this trial showed that among patients with severe, symptomatic aortic stenosis who were at low surgical risk, the rate of the composite end point of death, stroke, or rehospitalization at 1 year was significantly lower with transcatheter aortic-valve replacement (TAVR) than with surgical aortic-valve replacement. Longer-term outcomes are unknown. We randomly assigned patients with severe, symptomatic aortic stenosis and low surgical risk to undergo either TAVR or surgery. The first primary end point was a composite of death, stroke, or rehospitalization related to the valve, the procedure, or heart failure. The second primary end point was a hierarchical composite that included death, disabling stroke, nondisabling stroke, and the number of rehospitalization days, analyzed with the use of a win ratio analysis. Clinical, echocardiographic, and health-status outcomes were assessed through 5 years. A total of 1000 patients underwent randomization: 503 patients were assigned to undergo TAVR, and 497 to undergo surgery. A component of the first primary end point occurred in 111 of 496 patients in the TAVR group and in 117 of 454 patients in the surgery group (Kaplan-Meier estimates, 22.8% in the TAVR group and 27.2% in the surgery group; difference, -4.3 percentage points; 95% confidence interval [CI], -9.9 to 1.3; P = 0.07). The win ratio for the second primary end point was 1.17 (95% CI, 0.90 to 1.51; P = 0.25). The Kaplan-Meier estimates for the components of the first primary end point were as follows: death, 10.0% in the TAVR group and 8.2% in the surgery group; stroke, 5.8% and 6.4%, respectively; and rehospitalization, 13.7% and 17.4%. The hemodynamic performance of the valve, assessed according to the mean (±SD) valve gradient, was 12.8±6.5 mm Hg in the TAVR group and 11.7±5.6 mm Hg in the surgery group. Bioprosthetic-valve failure occurred in 3.3% of the patients in the TAVR group and in 3.8% of those in the surgery group. Among low-risk patients with severe, symptomatic aortic stenosis who underwent TAVR or surgery, there was no significant between-group difference in the two primary composite outcomes.

Current treatment recommendations for patients with heart failure and secondary mitral regurgitation include transcatheter edge-to-edge repair and mitral-valve surgery. Data from randomized trials comparing these therapies are lacking in this patient population. In this noninferiority trial conducted in Germany, patients with heart failure and secondary mitral regurgitation who continued to have symptoms despite guideline-directed medical therapy were randomly assigned, in a 1:1 ratio, to undergo either transcatheter edge-to-edge repair (intervention group) or surgical mitral-valve repair or replacement (surgery group). The primary efficacy end point was a composite of death, hospitalization for heart failure, mitral-valve reintervention, implantation of an assist device, or stroke within 1 year after the procedure. The primary safety end point was a composite of major adverse events within 30 days after the procedure. A total of 210 patients underwent randomization. The mean (±SD) age of the patients was 70.5±7.9 years, 39.9% were women, and the mean left ventricular ejection fraction was 43.0±11.7%. Within 1 year, at least one of the components of the primary efficacy end point occurred in 16 of the 96 patients with available data (16.7%) in the intervention group and in 20 of the 89 with available data (22.5%) in the surgery group (estimated mean difference, -6 percentage points; 95% confidence interval [CI], -17 to 6; P<0.001 for noninferiority). A primary safety end-point event occurred in 15 of the 101 patients with available data (14.9%) in the intervention group and in 51 of the 93 patients with available data (54.8%) in the surgery group (estimated mean difference, -40 percentage points; 95% CI, -51 to -27; P<0.001). Among patients with heart failure and secondary mitral regurgitation, transcatheter edge-to-edge repair was noninferior to mitral-valve surgery with respect to a composite of death, rehospitalization for heart failure, stroke, reintervention, or implantation of an assist device in the left ventricle at 1 year.
