Haloperidol for preventing delirium in ICU patients: A systematic review and meta-analysis
No full textOBJECTIVE: Delirium, a common behavioral manifestation of acute brain dysfunction in Intensive Care Unit (ICU), is a significant contributor to mortality and worse long-term outcome. Antipsychotics, especially haloperidol, are commonly administered for the treatment and prevention of delirium in critically ill patients while the evidence for the safety and efficacy of these drugs is still lacking. Therefore, we conducted a systematic review of the benefits of haloperidol for the prevention of delirium in ICU patients. MATERIALS AND METHODS: We made a systematic review and meta-analysis. RESULTS: Eight RCTs with 2806 patients were included. The prophylactic use of haloperidol did not reduce the delirium incidence (RR: 0.90, 95% CI: 0.69-1.71), the duration of delirium (MD: -0.33, 95% CI: -1.25-0.588) and the delirium/coma free days (MD: 0.08, 95% CI: -0.06-0.23). We did not find an increase of extrapyramidal effects (RR: 1.86, 95% CI: 0.30-11.39), QTc prolongation (RR: 1.11, 95% CI: 0.79-1.55) and arrhythmias (RR: 1.26, 95% CI: 0.72-2.19). The use of haloperidol did not increase the ICU (MD: 0.77, 95% CI: -0.28-1.83) and hospital length of stay (MD: -0.57, 95% CI: -1.32-0.18). Haloperidol did not increase the sedation level (RR: 1.88, 95% CI: 0.76-4.63) and mortality (RR: 0.97, 95% CI: 0.83-1.18). CONCLUSIONS: Haloperidol did not reduce the delirium incidence, the delirium duration, the delirium/coma free-days and did not increase the incidence of extrapyramidal effects, arrhythmias, the ICU and hospital length of stays and sedation
The Brain-gut Axis-where are we now and how can we Modulate these Connections?
No full textA traumatic brain injury (TBI) initiates an inflammatory response with molecular cascades triggered by the presence of necrotic debris, including damaged myelin, hemorrhages and injured neuronal cells. Molecular cascades prominent in TBI-induced inflammation include the release of an excess of proinflammatory cytokines and angiogenic factors, the degradation of tight junctions (TJs), cytoskeletal rearrangements and leukocyte and protein extravasation promoted by increased expression of adhesion molecules. The brain-gut axis consists of a complex network involving neuroendocrine and immunological signaling pathways and bi-directional neural mechanisms. Importantly, modifying the gut microbiome alters this axis, and in turn may influence brain injury and neuroinflammatory processes. In recent years it has been demonstrated that the activity and composition of the gastrointestinal (GI) microbiome population influences the brain through all of above-mentioned pathways affecting homeostasis of the central nervous system (CNS). The GI microbiome is involved in the modulation of cellular and molecular processes which are fundamental to the progression of TBI-induced pathologies, including neuroinflammation, abnormal blood brain barrier (BBB) permeability, immune system responses, microglial activation, and mitochondrial dysfunction. It has been postulated that interaction between the brain and gut microbiome occurs mainly via the enteric nervous system and the vagus nerve through neuroactive compounds including serotonin or dopamine and activation by bacterial metabolites including endotoxin, neurotransmitters, neurotrophic factors, and cytokines. In recent years the multifactorial impact of selected immunomodulatory drugs on immune processes occurring in the CNS and involving the brain-gut axis has been under intensive investigation

The use of carbon dioxide (CO2) atmosphere during cardiac surgery may reduce the risk of cerebral air microembolism. The aim of our study was to assess the influence of CO2 field flooding on microembolism-induced brain damage assessed by the level of S100ß protein, regarded as a marker of brain damage.Materials and methods: A group of 100 patients undergoing planned mitral valve operation through median sternotomy using standard CPB was recruited for the study. Echocardiography was performed prior to and after the CPB. CO2 insufflation at 6 L/minute was conducted in the study group. Blood samples for S100ß protein analysis were collected after induction of anesthesia, 2 hours after aorta de-clamping, and 24 hours after operation.Results: The S100ß level in blood plasma did not differ significantly between the study and the control group (0.13±0.08 µg/L, 1.12±0.59 µg/L, and 0.26±0.23 µg/L and 0.18±0.19 µg/L, 1.31±0.62 µg/L, and 0.23±0.12 µg/L, P=0.7, 0.14, and 0.78). The mean increase of the S100ß concentration was 13% lower in the group with CO2 protection than in the control group (0.988 µg/L vs 1.125 µg/L), although statistically insignificant. Tricuspid valve annuloplasties (TVAs) had significant impact on the increase in S100ß concentration in the treatment group after 24 hours (TVA [-] 0.21±0.09 vs TVA [+] 0.42±0.42, P=0.05). In patients >60 years, there were significant differences in the S100ß level 2 and 24 hours after the procedure (1.59±0.682 µg/L vs 1.223±0.571 µg/L, P=0.048, and 0.363±0.318 µg/L vs 0.229±0.105 µg/L, P=0.036) as compared with younger patients.Conclusion: The increase in S100ß concentration was lower in the group with CO2 protection than in the control group. Age and an addition of TVA significantly influenced the level of S100ß concentration in the tests performed 2 hours after aortic clamp release.

Decompressive Craniectomy Improves QTc Interval in Traumatic Brain Injury Patients
No full textBackground: Traumatic brain injury (TBI) is commonly associated with cardiac dysfunction, which may be reflected by abnormal electrocardiograms (ECG) and/or contractility. TBI-related cardiac disorders depend on the type of cerebral injury, the region of brain damage and the severity of the intracranial hypertension. Decompressive craniectomy (DC) is commonly used to reduce intra-cranial hypertension (ICH). Although DC decreases ICH rapidly, its effect on ECG has not been systematically studied. The aim of this study was to analyze the changes in ECG in patients undergoing DC. Methods: Adult patients without previously known cardiac diseases treated for isolated TBI with DC were studied. ECG variables, such as: spatial QRS-T angle (spQRS-T), corrected QT interval (QTc), QRS and T axes (QRSax and Tax, respectively), STJ segment and the index of cardio-electrophysiological balance (iCEB) were analyzed before DC and at 12–24 h after DC. Changes in ECG were analyzed according to the occurrence of cardiac arrhythmias and 28-day mortality. Results: 48 patients (17 female and 31 male) aged 18–64 were studied. Intra-cranial pressure correlated with QTc before DC (p < 0.01, r = 0.49). DC reduced spQRS-T (p < 0.001) and QTc interval (p < 0.01), increased Tax (p < 0.01) and changed STJ in a majority of leads but did not affect QRSax and iCEB. The iCEB was relatively increased before DC in patients who eventually experienced cardiac arrhythmias after DC (p < 0.05). Higher post-DC iCEB was also noted in non-survivors (p < 0.05), although iCEB values were notably heart rate-dependent. Conclusions: ICP positively correlates with QTc interval in patients with isolated TBI, and DC for relief of ICH reduces QTc and spQRS-T. However, DC might also increase risk for life-threatening cardiac arrhythmias, especially in ICH patients with notably prolonged QTc before and increased iCEB after DC

No full textKatarzyna Kotfis,1 Aleksandra Szylińska,2 Mariusz Listewnik,3 Mirosław Brykczyński,3 E Wesley Ely,4,5 Iwona Rotter21Department of Anesthesiology, Intensive Therapy and Acute Intoxications, Pomeranian Medical University, Szczecin, Poland; 2Department of Medical Rehabilitation and Clinical Physiotherapy, Pomeranian Medical University, Szczecin, Poland; 3Department of Cardiac Surgery, Pomeranian Medical University, Szczecin, Poland; 4Division of Allergy, Pulmonary, and Critical Care Medicine, Department of Medicine, Vanderbilt University Medical Center, Nashville, TN, USA; 5Geriatric Research, Education and Clinical Center (GRECC) Service, Department of Veterans Affairs Medical Center, Tennessee Valley Healthcare System, Nashville, TN, USA Introduction: Postoperative delirium (POD) is a common complication of cardiac surgery associated with increased mortality, morbidity, and long-term cognitive dysfunction. Diabetic patients, especially those with poor diabetes control and long-standing hyperglycemia, may be at risk of developing delirium. The aim of this study was to analyze whether the occurrence of POD in cardiac surgery is associated with diabetes or elevated preoperative glycated hemoglobin (HbA1c) level.Materials and methods: We performed a cohort analysis of prospectively collected data from a register of cardiac surgery department of a university hospital. Delirium assessment was performed twice a day during the first 5 days after the operation based on Diagnostic Statistical Manual of Mental Disorders, fifth edition criteria.Results: We analyzed a cohort of 3,178 consecutive patients, out of which 1,010 (31.8%) were diabetic and 502 (15.8%) were diagnosed with POD. Patients with delirium were more often diabetic (42.03% vs 29.86%, P<0.001) and on oral diabetic medications (34.66% vs 24.07%, P<0.001), no difference was found in patients with insulin treatment. Preoperative HbA1c was elevated above normal (≥6%) in more delirious than nondelirious patients (44.54% vs 33.04%, P<0.001), but significance was reached only in nondiabetic patients (20.44% vs 14.86%, P=0.018). In univariate analysis, the diagnosis of diabetes was associated with an increased risk of developing POD (OR: 1.703, 95% CI: 1.401–2.071, P<0.001), but only for patients on oral diabetic medications (OR: 1.617, 95% CI: 1.319–1.983, P<0.001) and an association was noted between HbA1c and POD (OR: 1.269, 95% CI: 1.161–1.387, P<0.001). Multivariate analysis controlled for diabetes showed that POD was associated with age, heart failure, preoperative creatinine, extracardiac arteriopathy, and preoperative HbA1c level.Conclusion: More diabetic patients develop POD after cardiac surgery than nondiabetic patients. Elevated preoperative HbA1c level is a risk factor for postcardiac surgery delirium regardless of the diagnosis of diabetes. Keywords: glycated hemoglobin, POD, mortality, outcome, IC

No full textKatarzyna Kotfis,1 Aleksandra Szylińska,2 Mariusz Listewnik,3 Marta Strzelbicka,1 Mirosław Brykczyński,3 Iwona Rotter,2 Maciej Żukowski1 1Department of Anesthesiology, Intensive Therapy and Acute Intoxications, Pomeranian Medical University, Szczecin, Poland; 2Department of Medical Rehabilitation and Clinical Physiotherapy, Pomeranian Medical University, Szczecin, Poland; 3Department of Cardiac Surgery, Pomeranian Medical University, Szczecin, Poland Introduction: Postoperative delirium is a common complication of cardiac surgery associated with increased mortality, morbidity, and long-term cognitive dysfunction. The aim of this study was to identify incidence and risk factors of delirium in elderly (≥65 years) and very elderly (≥80 years) patients undergoing major cardiac surgery. Materials and methods: We performed a retrospective cohort analysis of prospectively collected data from a register of the cardiac surgery department of a tertiary referral university hospital between 2014 and 2016. Analysis was performed in two groups, ≥65 years and ≥80 years. Results: We analyzed 1,797 patients ≥65 years, including 230 (7.24%) patients ≥80 years. Delirium was diagnosed in 21.4% (384/1,797) of patients above 65 years, and in 33.5% (77/230) of octogenarians. Early mortality did not differ between patients with and without delirium. Intensive care unit (ICU) stay (p<0.001), hospital stay (p<0.001), and intubation time (p=0.002) were significantly longer in patients undergoing cardiac surgery ≥65 years with delirium. According to multivariable analysis, ≥65 years, age (odds ratio [OR] 1.036, p=0.002), low ejection fraction (OR 1.634, p=0.035), diabetes (1.346, p=0.019), and extracardiac arteriopathy (OR 1.564, p=0.007) were found to be independent predictors of post-cardiac surgery delirium. Postoperative risk factors for developing delirium ≥65 years were atrial fibrillation (1.563, p=0.001), postoperative pneumonia (OR 1.896, p=0.022), elevated postoperative creatinine (OR 1.384, p=0.004), and prolonged hospitalization (OR 1.019, p=0.009). Conclusion: Patients above 65 years of age with postoperative delirium have poorer outcome and are more likely to have prolonged hospitalization and ICU stay, and longer intubation times, but 30-day mortality is not increased. In our study, eight independent risk factors for development of post-cardiac surgery delirium were age, low ejection fraction, diabetes, extracardiac arteriopathy, postoperative atrial fibrillation, pneumonia, elevated creatinine, and prolonged hospitalization time. Keywords: elderly, age, delirium, cardiac surgery, risk factors, mortality, outcom
Balancing intubation time with postoperative risk in cardiac surgery patients – a retrospective cohort analysis
No full textKatarzyna Kotfis,1 Aleksandra Szylińska,2 Mariusz Listewnik,3 Kacper Lechowicz,1 Monika Kosiorowska,3 Sylwester Drożdżal,1 Mirosław Brykczyński,3 Iwona Rotter,2 Maciej Żukowski1 1Department of Anesthesiology, Intensive Therapy and Acute Intoxications, Pomeranian Medical University, Szczecin, Poland; 2Department of Medical Rehabilitation and Clinical Physiotherapy, Pomeranian Medical University, Szczecin, Poland; 3Department of Cardiac Surgery, Pomeranian Medical University, Szczecin, Poland Introduction: Intubation time in patients undergoing cardiac surgery may be associated with increased mortality and morbidity. Premature extubation can have serious adverse physiological consequences. The aim of this study was to determine the influence of intubation time on morbidity and mortality in patients undergoing cardiac surgery.Methods: We performed a retrospective analysis of data on 1,904 patients undergoing isolated coronary artery bypass grafting (CABG) and stratified them by duration of intubation time after surgery – 0–6, 6–9, 9–12, 12–24 and over 24 hours. Postoperative complications risk analysis was performed using multivariate logistic regression analysis for patients extubated ≤12 and >12 hours.Results: Intubation percentages in each time cohort were as follows: 0–6 hours – 7.8%, 6–9 hours – 17.3%, 9–12 hours – 26.8%, 12–24 hours – 44.4% and >24 hours – 3.7%. Patients extubated ≤12 hours after CABG were younger, mostly males, more often smokers, with lower preoperative risk. They had lower 30-day mortality (2.02% vs 4.59%, P=0.002), shorter hospital stay (7.68±4.49 vs 9.65±12.63 days, P<0.001) and shorter intensive care unit stay (2.39 vs 3.30 days, P<0.001). Multivariate analysis showed that intubation exceeding 12 hours after CABG increases the risk of postoperative delirium (OR 1.548, 95% CI 1.161–2.064, P=0.003) and risk of postoperative hemofiltration (OR 1.302, 95% CI 1.023–1.657, P=0.032).Conclusion: Results indicate that risk of postoperative complications does not increase until intubation time exceeds 12 hours. Shorter intubation time is seen in younger, men and smokers. Intubation time >12 hours is a risk factor for postoperative delirium and hemofiltration after cardiac surgery. Keywords: intubation, cardiac surgery, CABG, mortality, complications, delirium
