Objective To systematically review the impacts of general anesthesia using sevoflurane versus propofol on the incidence of emergence agitation in pediatric patients. Methods Such databases as PubMed, EMbase, Web of Science, The Cochrane Library (Issue 4, 2012), CNKI, CBM, WanFang Data and VIP were electronically searched from inception to December 2012, for comprehensively collecting randomized controlled trials (RCTs) on the impacts of general anesthesia using sevoflurane versus propofol on the incidence of emergence agitation in pediatric patients. References of included studies were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.1 software. Results A total of 9 RCTs involving 692 children were included, of which, six were pooled in the meta-analysis. The results of meta-analysis showed that: a) after anesthesia induction using sevoflurane, intravenous propofol maintenance was associated with a lower incidence of emergence agitation compared with sevoflurane maintenance (RR=0.57, 95%CI 0.39 to 0.84, P=0.004); and b) patients anesthetized with total intravenous propofol had a lower incidence of emergence agitation compared with total inhalation of sevoflurane (RR=0.16, 95%CI 0.06 to 0.39, Plt;0.000 1). Conclusion The incidence of emergence agitation after general anesthesia using sevoflurane is higher than that using propofol. Due to the limited quantity and quality, the application of sevoflurane should be chosen based on full consideration into patients’ conditions in clinic.

Objective To investigate the clinical features, etiology and treatment strategies of patients with delirium in emergency intensive care unit ( EICU) . Methods Patients with delirium during hospitalization between January 2010 and January 2012 were recruited from respiratory group of EICU of Beijing Anzhen Hospital. Over the same period, same amount of patients without delirium were randomly collected as control. The clinical datawere retrospectively analyzed and compared. Results The incidence of delirium was 7.5% ( 42/563) . All delirium patients had more than three kinds of diseases including lung infections, hypertension, coronary heart disease, respiratory failure, heart failure, renal failure, hyponatremia, etc. 50% of delirium patients received mechanical ventilation ( invasive/noninvasive) . The mortality of both the delirium patients and the control patients was 11.9% ( 5 /42) . However, the patients with delirium exhibited longer hospital stay [ 14(11) d vs. 12(11) d, P gt;0. 05] and higher hospitalization cost [ 28, 389 ( 58,999) vs. 19, 373( 21, 457) , P lt;0.05] when compared with the control group. 52.4% ( 22/42) of delirium patients were associated with primary disease. 9. 5% ( 4/42) were associated with medication. 38. 1% (16/42) were associated with ICU environment and other factors. Conclusions Our data suggest that the causes of delirium in ICU are complex. Comprehensive treatment such as removal of the relevant aggravating factors, treating underlying diseases, enhancing patient communication, and providing counseling can shorten their hospital stay, reduce hospitalization costs, and promote rehabilitation.
Delirium is an acute, transient, usually reversible, fluctuating disturbance in consciousness, attention, cognition, and perception. Delirium after cardiac operations is associated with increased morbidity, reduced cognitive functioning, increased short-term and long-term mortality, longer hospitalization and higher hospitalization cost. The diagnosis, prevention and treatment of delirium are of great importance for perioperative care of patients undergoing cardiac surgery. Effective delirium screening tools are very helpful for the recognition and monitoring of delirium after cardiac surgery. In recent years, there has been many new strategies for the treatment, nursing care and prevention of delirium after cardiac surgery. This review focuses on the incidence, risk factors, diagnostic methods, treatment and preventive strategies of delirium after cardiac surgery.
Objective To analyze the risk factors for delirium of the Stanford A aortic dissection patients after surgery. Method We retrospectively analyzed the clinical data of 335 patients with type A aortic dissection in Guangdong Cardiac Institution from January 2012 through December 2014. There were 280 males and 55 females. The average of age was 48.5±10.3 years. Delirium status of the patients were evaluated based on confusion assessment method for intensive care unit (CAM-ICU). The patients were divided into two groups including a delirium group and a control group. We tried to find the risk factors for postoperative delirium. Results There were 169 patients of delirium with a incident rate of 50.4%. One-way analysis of variance and multivariate analysis indicated that pre-operative D-dimer level (OR=2.480, 95% CI 1.347-4.564, P<0.01), the minimum mean arterial pressure during operation (OR=0.667, 95% CI 0.612-0.727, P<0.01), the postoperative ventilation time (OR=2.771, 95% CI 1.506-5.101, P<0.01) and the postoperative acute kidney failure (OR=1.911, 95% CI 1.065-3.430, P<0.05) were the independent risk factors for delirium of the Stanford A aortic dissection patient after surgery. Conclusion The incident rate of postoperative delirium of the Standford A aortic dissection patient is relatively high. Patients in this study with elevated pre-operative D-dimer level, lower intraoperative mean arterial pressure, longer postoperative ventilation and combination of acute kidney failure have a higher rate of postoperative delirium. Better understanding and intervention of these factors are meaningful to reduce the occurrence of postoperative delirium.
ObjectivesTo systematically review the clinical efficacy and safety of antipsychotics for delirium. MethodsDatabases including The Cochrane Library (Issue 5, 2015), PubMed, MEDLINE, EMbase, CNKI, VIP and WanFang Data were electronically searched for randomized controlled trials (RCTs) about antipsychotics compared with placebo/blank for delirium from inception to May 2015. We also hand-searched related conference proceedings and references of included studies for additional studies. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was conducted by using RevMen 5.3 software. ResultsA total of 7 RCTs involving 712 patients were included. The results of meta-analysis showed that there were no significant differences between the antipsychotics group and the placebo/blank group in mortality (RR=1.00, 95%CI 0.90 to 1.10, P=0.99), duration of delirium (MD=-1.53, 95%CI -4.95 to 1.89, P=0.38), length of stay (MD=-0.89, 95%CI -7.69 to 5.90, P=0.80), and ICU stay time (MD=-3.70, 95%CI -15.83 to 8.43, P=0.55). Compared with the placebo/ blank group, the antipsychotics could reduce the severity of delirium (SMD=-1.62, 95%CI -2.32 to -0.93, P<0.000 01). ConclusionCurrent evidence shows that the efficacy of antipsychotics in the treatment of delirium is not clear. Due to the limited quantity and quality of the included studies, the above conclusion needs to be further verified by more high quality studies.
Objective To evaluate the influence of early mobilization on delirium and respiratory dynamics in mechanically ventilated patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods The study prospectively recruited 107 AECOPD patients who admitted between January 2014 and June 2015 and underwent mechanical ventilation.On basis of same routine treatment,the patients were randomly divided into a treatment group (54 cases)receiving regime of early mobilization,and a control group (53 cases)receiving routine sedation and analgesia treatment.The incidence of delirium,duration of delirium,time of mechanical ventilation,and ICU mortality were compared between two groups.The respiratory mechanical parameters including endogenous positive end expiratory pressure (PEEPi),airway resistance(Raw),static compliance(Cs),and dynamic compliance(Cd)before treatment,3 days and 5 days after treatment were also compared between two groups. Results Compared with the control group,the incidence of delirium decreased (59.3% vs. 77.4%),the duration of delirium [(1.8±1.1)d vs. (2.6±1.3)d] and mechanical ventilation[(6.2±3.4)d vs. (7.9±4.2)d] reduced in the treatment group with significant difference(P<0.05).There was no significant difference in respiratory mechanical parameters before treatment between two groups(P>0.05).While at 3 days and 5 days after treatment,PEEPi decreased [(6.23±2.83)cm H2O vs. (7.42±2.62)cm H2O,(4.46±2.20)cm H2O vs. (5.92±2.51)cm H2O],Raw decreased [(20.35±7.15)cmH2O·L-1·s-1 vs. (23.23±6.64)cm H2O·L-1·s-1,(16.00±5.41)cm H2O·L-1·s-1 vs. (19.02±6.37)cm H2O·L-1·s-1],Cd increased [(25.20±9.37)mL/cm H2O vs (21.75±7.38)mL/cm H2O,(27.46±5.45)mL/cm H2O vs. (24.40±6.68)mL/cm H2O] in the treatment group compared with the control group(P<0.05),and the difference in Cs was not significant(P>0.05).No complications such as slippage,physical injury,or malignant arrhythmia occurred in two groups.The mortality slightly decreased in the treatment group compared with the control group (5.6% vs 11.3%),but the difference was not statistically significant(P>0.05). Conclusions The incidence of delirium is high in mechanically ventilated patients with AECOPD.Early mobilization can reduce the incidence and duration of delirium,decrease the airway resistance,increase the dynamic lung compliance,relieve dynamic pulmonary hyperinflation and reduce PEEPi,so as to improve the respiratory function and shorten the time of mechanical ventilation.Therefore,early mobilization is an effective and safe regime for AECOPD patients underwent mechanical ventilation.
