“…Our investigation supports this result. Although the role of postoperative electrolyte disorders in postoperative delirium is still debatable [15, 22, 23], the presence of an electrolyte disorders or an abnormal electrolyte channel is associated with many neuropsychiatric disorders including AD [24], dementia [25] and depression [26]. Cisternas et al found that an increased potassium intake can improve cognitive performance and might be important in the prevention of AD onset [27].…”

“…Several previous studies have shown that fluid/electrolyte disorders are closely related to postoperative delirium [7, 15, 16], but the influence of different electrolytes on postoperative delirium remains controversial. Some studies have suggested that a disturbance in potassium or sodium levels might be a factor in postoperative delirium [16, 29], but Caplan’s study [19] found that significantly lower serum levels of magnesium and phosphate, not potassium, were associated with delirium.…”

BackgroundAt present, the exact mechanism of postoperative delirium has not been elucidated. The purpose of this study was to analyze the incidence of delirium in patients undergoing orthopedic surgeries and to explore possible related factors.MethodsThis is a retrospective study. We used 582 patients who had undergone orthopedic surgery between January 2011 and December 2014. The surgeries consisted of 155 cases of internal fixation for intertrochanteric fracture (IFIF), 128 cases of femoral head replacement (FHR), 169 cases of total hip arthroplasty (THA) and 130 cases of total knee arthroplasty (TKA). Among the 582 patients, 75 developed postoperative delirium (an incidence of 12.9%). The demographics of the patients, which included age, gender, operation duration and blood loss, were statistically analyzed with univariate logistic regression analysis and then multivariate logistic regression. To investigate the influences of different electrolytes disorders for postoperative delirium, the Chi-square test was used.ResultsMultivariate logistic regression analysis indicated that postoperative delirium incidence in patients aged 70–79 years and in patients aged ≥80 years was higher than that in patients aged <70 years, odds ratio (OR) values were 6.33 and 26.37, respectively. In addition, the incidence of postoperative delirium in the group of patients with electrolyte disorders was higher than that in the normal group (OR, 2.38). There were statistically significant differences between the delirium group and the non-delirium group in the incidences of the sodium and calcium disorders.ConclusionsAging and postoperative electrolyte disorders (hyponatremia and hypocalcemia) are risk factors for postoperative delirium in patients undergoing orthopedic surgeries.

“…However, elderly patients predispose to develop delirium after CABG (Deiner & Silverstein, ; Kobayashi et al, ; Loponen et al, ; Otomo, Maekawa, Goto, Baba, & Yoshitake, ; Smulter, Lingehall, Gustafson, Olofsson, & Engstrom, ). The incidence of postoperative delirium (POD) after CABG is 6% to 15% (Loponen et al, ; Yilmaz et al, ; W. Y. Zhang et al, ) in general and 46% to 73% (Khadka, McAlinden, & Pesudovs, ; Smith & Dimsdale, ) among patients aged 60 or older.…”

“…The risk characteristics of the group were comparable to the European average, based on the Euroscore scale. The high level of care offered to the patients is obvious if one takes into account the zero mortality (international margins 0%-3%) within the study group, as well as the excellent results in concern to the clinical indicators and the low rate of complications in general, compared to the internationally accepted [24][25][26][27][28] -Table 1. Despite that, the hospital length of stay reached an average of 11.5 days.…”

Background. Aim of the current prospective study is to investigate and revise the basic information related to the coronary artery bypass graft (CABG) procedure, in an attempt to reevaluate the current Greek Diagnosis Related Groups (DRGs) system. Methods. In a Greek academic cardiothoracic surgical department, implementing clinical therapeutic protocols, we prospectively recruited 75 patients planned to undergo elective CABG. All basic demographic, medical and perioperative data were gathered in an extensive database, so as to be compared with data predicted by the DRG's system. Clinical indicators of performance aiming towards quality control were: perioperative mortality, postoperative myocardial infarct, postoperative stroke, postoperative renal failure, total hospital length of stay, rate of reoperation and rate of readmission. Results. None of the study patients deceased. No cases of perioperative myocardial infarct, stroke or renal failure were observed. Two of the patients developed respiratory failure, and one was reoperated for the control of perioperative bleeding. There were no cases of readmission to the hospital. The total length of stay was longer than the DRG's prediction (mean 11.5 vs 7 days), owed partially to the preoperative stay (mean 3.18 days) in the department, due to reasons of medical vigilance and organisatory problems that led to the postponement of the operation. Conclusions. A review of the CABG related DRG's in Greece seems appropriate, based on the findings of the current study, suggesting a longer than predicted hospital stay.
