Chlorpromazine's Potential Role in Palliating Distressing Symptoms Associated With Hyperactive Delirium in Patients at End of Life.

Background: The hyperactive subtype of delirium is characterized by agitation, restlessness, delusions, and/or hallucinations, which commonly present near end of life (EoL). Symptom relief often requires the use of medications, such as chlorpromazine (CPZ), to reduce patient distress by inducing proportional sedation. Objective: The purpose of this study was to evaluate CPZ's potential role in managing the distress of hyperactive delirium in patients receiving EoL care. Methods: A retrospective observational study among hospitalized patients with advanced cancer at EoL between January 2020 to December 2021. Results: Sustained improvement in symptoms of delirium was seen in 80% of patients as identified in the palliative psychiatrist's progress notes. Meanwhile, 75% of patient's improvement was reported in nursing-driven Delirium Observation Screening Scale. Conclusion: This study elucidates that at doses of ∼100 mg/day, CPZ is potentially an effective medication for patients with advanced cancer, experiencing hyperactive delirium in their final week of life.

Clonidine for preventing emergence agitation in infants (PREVENT AGITATION II): Protocol and statistical analysis plan.

BACKGROUND: Emergence agitation is a common clinical condition in children. Symptoms pertaining to the spectrum of early postoperative negative behavior typically occur upon emergence from anesthesia. Clonidine is an effective adjunctive agent for the prevention of emergence agitation in children, but evidence in the smallest age groups is sparse We aim to investigate the efficacy and safety of an intraoperative bolus of intravenous clonidine for preventing emergence agitation in children 3-12 months of age. METHODS: This is a randomized, placebo-controlled, double-blind trial. We will enroll 320 patients aged 3-12 months who have been scheduled for general anesthesia maintained with sevoflurane and opioid. The randomization is parallel and stratified by age group, sex, and site. The investigational medicinal product will be administered intravenously ~20 min before the anticipated end of the surgical procedure. The intervention is clonidine 3 µg/kg and placebo is isotonic saline in a corresponding volume. RESULTS: The primary outcome is the incidence of emergence agitation as assessed on the Watcha scale, that is, any Watcha score >2 during participants' stay in the postanesthetic care unit. Secondary outcomes are the proportion of participants with postoperative pain, with postoperative nausea and vomiting, and a composite safety outcome. Statistical analysis will be conducted according to the Statistical Analysis Plan with the intention-to-treat population for our primary analyses. CONCLUSION: The PREVENT AGITATION II trial will contribute valuable knowledge on efficacy for the prevention of emergence agitation and safety in infants.

Effect of a repeated verbal reminder of orientation on emergence agitation after general anaesthesia for minimally invasive abdominal surgery: a randomised controlled trial.

BACKGROUND: An orientation strategy providing repeated verbal reminders of time, place, and person has been widely used for the non-pharmacological management of delirium. We hypothesised that using this strategy could reduce emergence agitation and improve recovery profiles. METHODS: This prospective observer-blinded RCT included male and female patients aged 18-70 yr undergoing minimally invasive abdominal surgery. During emergence from general anaesthesia, subjects in the orientation group (n=57) were provided a repeated reminder, including orientation: '(Patient's name), you are now recovering from general anaesthesia after surgery at Seoul National University Hospital, open your eyes!' via noise-cancelling headphones, whereas those in the control group (n=57) only heard their name: '(Patient's name), open your eyes!'. The primary outcome was the incidence of emergence agitation (Riker sedation agitation scale [SAS] ≥5). The incidence of dangerous agitation (SAS=7), maximal SAS score in the operating room, and recovery profile until 24 h postoperatively were evaluated as secondary outcomes. RESULTS: The incidence of emergence agitation in the operating room was significantly lower in the orientation group than in the control group (16/57 [28.1%] vs 38/57 [66.7%]; relative risk [95% confidence interval], 0.5 [0.3-0.7]; P<0.001). The incidence of dangerous agitation (0 [0.0%] vs 10 [17.5%], P=0.001) and the median maximal SAS score (4 [4-5] vs 5 [4-6], P<0.001) were also lower in the orientation group. Secondary outcomes, other than agitation-related variables, were comparable between the two groups. CONCLUSIONS: Repeated verbal stimulation of orientation may serve as a simple and easily applicable strategy to reduce emergence agitation after general anaesthesia. CLINICAL TRIAL REGISTRATION: NCT05105178.

Adjuvant anticholinergic therapy for the prevention of akathisia in patients with primary headache in the emergency department: A systematic review.

OBJECTIVES: Adjunct therapy with anticholinergic agents has been proposed to reduce the incidence of extrapyramidal side effects such as akathisia following treatment with neuroleptics or metoclopramide. This systematic review assessed the effectiveness of anticholinergic agents to prevent neuroleptic or metoclopramide-induced akathisia in patients presenting to the emergency department (ED) with benign headache. METHODS: Eight electronic databases and the gray literature were searched to identify randomized controlled trials involving adult patients presenting to the ED with primary headache treated with neuroleptic or metoclopramide. Study selection, data extraction, and quality assessment were completed by two independent reviewers. Individual or pooled meta-analysis of dichotomous outcomes were calculated as relative risks (RRs) with 95% confidence intervals (CIs) using a random-effects model. Heterogeneity was assessed using the I2 statistic. RESULTS: A total of 1032 studies were screened, of which two studies were included in the review. Both studies provided patients with diphenhydramine following treatment with neuroleptics or metoclopramide. Treatment with diphenhydramine did not reduce the incidence of akathisia compared to treatment with placebo (RR 0.83, 95% CI 0.43-1.61, I2  = 0%). The impact of diphenhydramine on pain relief, need for rescue medications, and relief of other extrapyramidal side effects was reported in one of the two studies, with no significant differences noted in any outcomes compared to patients treated with placebo. CONCLUSION: This review found insufficient evidence to recommend the use of diphenhydramine as an adjunct therapy to prevent akathisia in ED patients treated with neuroleptics or metoclopramide for primary headache. This finding relies on the results of two small randomized controlled trials with incomplete outcome reporting. Additional high-quality studies are needed to better understand the clinical efficacy of agents with anticholinergic properties in the ED management of patients with primary headaches.

Cerebrospinal fluid metabolic profiling reveals divergent modulation of pentose phosphate pathway by midazolam, propofol and dexmedetomidine in patients with subarachnoid hemorrhage: a cohort study.

BACKGROUND: Agitation is common in subarachnoid hemorrhage (SAH), and sedation with midazolam, propofol and dexmedetomidine is essential in agitation management. Previous research shows the tendency of dexmedetomidine and propofol in improving long-term outcome of SAH patients, whereas midazolam might be detrimental. Brain metabolism derangement after SAH might be interfered by sedatives. However, how sedatives work and whether the drugs interfere with patient outcome by altering cerebral metabolism is unclear, and the comprehensive view of how sedatives regulate brain metabolism remains to be elucidated. METHODS: For cerebrospinal fluid (CSF) and extracellular space of the brain exchange instantly, we performed a cohort study, applying CSF of SAH patients utilizing different sedatives or no sedation to metabolomics. Baseline CSF metabolome was corrected by selecting patients of the same SAH and agitation severity. CSF components were analyzed to identify the most affected metabolic pathways and sensitive biomarkers of each sedative. Markers might represent the outcome of the patients were also investigated. RESULTS: Pentose phosphate pathway was the most significantly interfered (upregulated) pathway in midazolam (p = 0.0000107, impact = 0.35348) and propofol (p = 0.00000000000746, impact = 0.41604) groups. On the contrary, dexmedetomidine decreased levels of sedoheptulose 7-phosphate (p = 0.002) and NADP (p = 0.024), and NADP is the key metabolite and regulator in pentose phosphate pathway. Midazolam additionally augmented purine synthesis (p = 0.00175, impact = 0.13481) and propofol enhanced pyrimidine synthesis (p = 0.000203, impact = 0.20046), whereas dexmedetomidine weakened pyrimidine synthesis (p = 0.000000000594, impact = 0.24922). Reduced guanosine diphosphate (AUC of ROC 0.857, 95%CI 0.617-1, p = 0.00506) was the significant CSF biomarker for midazolam, and uridine diphosphate glucose (AUC of ROC 0.877, 95%CI 0.631-1, p = 0.00980) for propofol, and succinyl-CoA (AUC of ROC 0.923, 95%CI 0.785-1, p = 0.000810) plus adenosine triphosphate (AUC of ROC 0.908, 95%CI 0.6921, p = 0.00315) for dexmedetomidine. Down-regulated CSF succinyl-CoA was also associated with favorable outcome (AUC of ROC 0.708, 95% CI: 0.524-0.865, p = 0.029333). CONCLUSION: Pentose phosphate pathway was a crucial target for sedatives which alter brain metabolism. Midazolam and propofol enhanced the pentose phosphate pathway and nucleotide synthesis in poor-grade SAH patients, as presented in the CSF. The situation of dexmedetomidine was the opposite. The divergent modulation of cerebral metabolism might further explain sedative pharmacology and how sedatives affect the outcome of SAH patients.

Effects of preoperative nasal spray esketamine on separation anxiety and emergence agitation in pediatric strabismus surgery: A randomized clinical trial.

OBJECTIVE: To investigate the effects of preoperative nasal spray esketamine on separation anxiety and postoperative emergence agitation in pediatric strabismus surgery. METHOD: Ninety children aged 3 to 6 years who underwent elective strabismus surgery were randomly divided into 3 groups that received 0.5 mg/kg (group S1), 1 mg/kg of esketamine (group S2), and the same volume of normal saline (group C) by nasal spray 10 minutes before surgery. The observation indicators of this test include the Ramsay sedation score, separation anxiety score, mask induction score, and the incidences of postoperative emergence agitation. Patient's heart rate, blood oxygen, post anesthesia care unit stay time, and any adverse events were recorded. RESULTS: The Ramsay sedation score was significantly lower in group C than those in groups S1 and S2 (P < .001). The separation anxiety scores and the mask induction scores were significantly higher in group C than those in groups S1 and S2 (P < .001). The incidences of emergence agitation in groups S1 and S2 were significantly lower than that in C group (P < .001). No obvious clinical complication was observed. CONCLUSION: Preoperative nasal spray esketamine reduced the preoperative separation anxiety and decrease emergence agitation in pediatric strabismus surgery.

The Impact of a Dementia-Friendly Garden Design on People With Dementia in a Residential Aged Care Facility: A Case Study.

BACKGROUND: There is a paucity of evidence on the efficacy of garden design based on dementia-friendly environment (DFE) characteristics on the level of agitation, apathy, and engagement of people with dementia in residential aged care facilities (RACFs). OBJECTIVE: To investigate the effect of a garden improved according to DFE characteristics on agitation, apathy, and engagement of people with dementia in one RACF. METHODS: A case study design with a mixed-method approach was used. RESULTS: There was no significant improvement in the level of participants' agitation following visits to the improved garden, χ2(2) = 5.167, p = .076. A high level of engagement was found in participants during the intervention (Week 1-1, p < .01; Week 1-2, p < .01; Week 2, p < .01; Week 3, p < .05; and Week 4, p < .05) when compared to before intervention (Week 0). A higher level of apathy was found in participants at Week 0 when compared to during the intervention (Week 1-1, p < .05; Week 1-2, p < .01; Week 2, p < .05; Week 3, p < .01; and Week 4, p < .01). Five themes emerged from participant interviews: the presence of sensory-provoking elements in the garden, meaningful engagement in the garden, accessibility of the garden, garden impacts, and garden experiences that demonstrated the effectiveness of the garden. CONCLUSIONS: The garden promoted engagement and decreased apathy of people with dementia living in the RACF with the researcher's partial facilitation of the intervention sessions. The qualitative findings indicated the effectiveness of the garden in reducing agitation.

Glial cell-derived neurotrophic factor decrease may mediate learning, memory and behavior impairments in rats after neonatal surgery.

Patients who have surgery during the first few years of their lives may have an increased risk of behavioral abnormality. Our previous study has shown a role of glial cell-derived neurotrophic factor (GDNF) in neonatal surgery-induced learning and memory impairment in rats. This study was designed to determine whether neonatal surgery induced hyperactive behavior in addition to learning and memory impairment and whether GDNF played a role in these changes. Postnatal day 7 male and female Sprague-Dawley rats were subjected to right common carotid arterial exposure under sevoflurane anesthesia. Their learning, memory and behavior were tested from 23 days after the surgery. GDNF was injected intracerebroventricularly at the end of surgery. Surgery reduced GDNF expression in the hippocampus. Surgery impaired learning and memory and induced a hyperactive behavior as assessed by Barnes maze, fear conditioning and open field tests. In addition, surgery reduced dendritic arborization and spine density. The effects were attenuated by GDNF injection. These results suggest that surgery induces a hyperactive behavior pattern, impairment of learning and memory, and neuronal microstructural damage later in the lives in rats. GDNF reduction may mediate these surgical effects.

The effect of two different doses of dexmedetomidine to prevent emergence agitation in children undergoing adenotonsillectomy: a randomized controlled trial.

OBJECTIVE: To evaluate different doses of dexmedetomidine for the prevention of emergence agitation in children undergoing adenotonsillectomy. METHOD: One hundred and thirty children aged 3-10 years scheduled for adenotonsillectomy were randomly assigned to two groups. Anesthesia was induced with 0.5 µg.kg-1 dexmedetomidine (DEX 0.5 group) or 1 µg.kg-1 dexmedetomidine (DEX 1 group) at the beginning of surgery. Observers who recorded the data in the postanesthesia care unit were blinded to the allocation. The primary outcome was the percentage of emergence agitation. The times to spontaneous breath, awake, extubate, and postanesthesia care unit stay were also recorded. RESULTS: One hundred twenty four children were randomized into two groups. Five children were excluded because of adverse events and dropout (DEX 0.5 group, n = 58; DEX 1 group, n = 62). No significant differences were noted in the percentage of emergence agitation between the two groups. The times to extubation (p = 0.003), awake, and postanesthesia care unit stay in DEX 0.5 group were shorter than those in DEX 1 group (p < 0.0001). There was no significant difference between the two groups in the time to spontaneous breath. Approximately 8% of patients in DEX 0.5 group and 18% patients in DEX 1 group presented low SpO2, showing a significant difference between the two groups (p = 0.043). CONCLUSIONS: A dose of 0.5 µg.kg-1 dexmedetomidine was equally effective as 1 µg.kg-1 dexmedetomidine in preventing emergence agitation. TRIAL REGISTRATION: The trial is currently completed recruitment, registered in ClinicalTrials.gov (ID:NCT03760809). Inclusion began on 4 January, 2019.

Implementation of the Evidence Integration Triangle for behavioral and psychological symptoms of dementia (EIT-4-BPSD) in care communities.

BACKGROUND: Federal regulations stipulate that behavioral interventions be used for behavioral and psychological symptoms of distress in dementia (BPSD). Care community staff have difficulty implementing these approaches. PURPOSE: This study tested an implementation strategy, the Evidence Integration Triangle for BPSD (EIT-4-BPSD), for assisting staff in the use of evidence-based behavioral approaches for BPSD. METHODS: About 55 care communities were randomized to EIT-4-BPSD or usual care; 553 residents were enrolled. The implementation strategy was delivered by research facilitators, staff, stakeholders, and champions over 12 months. It involved four components: Environment and policy assessments; Staff education; Establishment of person-centered care plans; and Mentoring and motivating staff. The implementation strategy was evaluated using the Reach, Effectiveness, Adoption, Implementation, Maintenance model. FINDINGS: There was no evidence for resident or care community effectiveness. There was evidence of adoption and implementation. DISCUSSION: EIT-4-BPSD was helpful as an implementation strategy and staff altered how care was provided.

Risk events during intrahospital transport of patients from the emergency department: a prospective observational study.

BACKGROUND: We aimed to determine the incidence, nature of and predisposing factors for risk events (REs) that occur during the intrahospital transport of patients from the ED. METHODS: We undertook a prospective, observational study of intrahospital patient transports from a single ED between 30 January and 20 March 2020. An investigator attended each transport and recorded any RE on a specifically designed data collection document. An RE was any mishap, even if not foreseen, that had the potential to cause the patient harm. A patient equipment number was assigned based on the number of pieces of equipment required during the transport. Poisson regression generated incidence rate ratios (IRRs) and determined risk factors for REs. RESULTS: Of 738 transports, 289 (39.1%, 95% CI 35.6% to 42.8%) had at least one RE. The total of 521 REs comprised 125 patient-related, 279 device-related and 117 line/catheter-related REs. The most common included trolley collisions (n=142), intravenous fluid line catching/tangling (n=93), agitation/aggression events (n=31) and cardiac monitoring issues (n=31). Thirty-four (6.5%) REs resulted in an undesirable patient outcome, most commonly distress and pain. Predisposing factors for REs included an equipment number ≥3 (IRR 5.68, 95% CI 3.95 to 8.17), transport to a general ward (IRR 2.68, 95% CI 2.12 to 3.39), hypertension (IRR 1.93, 95% CI 1.07 to 3.50), an abnormal temperature and a GCS<14. CONCLUSIONS: REs are common in transport of patients from the ED and can result in undesirable patient outcomes. Adequate pre-transfer preparation, especially securing equipment and lines, would result in a reduced risk.

Effects of Intraoperative Auditory Stimulation on Pain and Agitation on Awakening After Pediatric Adenotonsillectomy: A Randomized Clinical Trial.

Importance: Severe pain on awakening (POA) and emergence delirium (ED) are common following pediatric adenotonsillectomy. Effective preventive interventions are lacking. Objective: To determine the effects of intraoperative auditory stimulation on reduction of POA and ED after pediatric adenotonsillectomy. Design, Setting, and Participants: Single-center, double-blinded, 4-armed, randomized clinical trial of children undergoing adenotonsillectomy from March 2018 to May 2019 at a tertiary care pediatric referral center. Interventions: Children were randomized to 1 of the following groups: auditory stimulation with music, auditory stimulation with noise, ambient noise insulation with masking earplugs, and a control group receiving no intervention. Ear inserts were placed in the operating room once general anesthesia was administered. Stimulation parameters were based on the preoperative audiological evaluation and the appropriate fitting of the transduction system, including ambient noise level monitoring. Main Outcomes and Measures: The primary outcome was POA levels measured on 10-point scales according to age-appropriate validated tools. The secondary outcome was ED levels assessed according to the Pediatric Anesthesia Emergence Delirium 20-point scale. Results: A total of 104 consecutive healthy children (median [interquartile range] age at surgery, 5.0 [3.8-6.4] years) were included in the analysis. Music had a large effect size on POA (0.63; 98% CI, 0.43-0.84) and a medium effect size on ED (0.47; 98% CI, 0.21-0.75), while noise had a medium effect size on POA (0.47; 98% CI, 0.22-0.73) and a large effect size on ED (0.63; 98% CI, 0.44-0.85) compared with controls. The earplugs group showed a small effect size on POA and ED. Considering a clinically meaningful threshold of greater than 4 for POA and 10 or greater for ED at dichotomized analysis, a large effect size was achieved by music (1.39; odds ratio [OR], 0.08; 98% CI, 0.02-0.29; and 0.84; OR, 0.22; 98% CI, 0.06-0.75, respectively) and noise (0.97; OR, 0.17; 98% CI, 0.05-0.6; and 1.48; OR, 0.07; 98% CI, 0.02-0.26, respectively), while earplugs resulted in a small effect size. Conclusions and Relevance: In this randomized clinical trial, children undergoing adenotonsillectomy who received intraoperative auditory stimulation demonstrated a clinically meaningful decrease in POA and ED in the immediate postoperative period. Further research is needed to assess whether intraoperative auditory stimulation may decrease POA and ED in children undergoing other types of surgical procedures.

Chronic Brain Failure.

Chronic brain failure, also known as dementia or major neurocognitive disorder, is a syndrome of progressive functional decline characterized by both cognitive and neuropsychiatric symptoms. It can be conceptualized like other organ failure syndromes and its impact on quality of life can be mitigated with proper treatment. Dementia is a risk factor for delirium, and their symptoms can be similar. Patients with dementia can present with agitation that can lead to injury. Logic and reason are rarely successful when attempting to redirect someone with advanced dementia. Interactions that offer a sense of choice are more likely to succeed.

Effect of ketamine on emergence agitation following septoplasty: a randomized clinical trial.

BACKGROUND AND OBJECTIVES: The risk of emergence agitation (EA) is high in patients undergoing nasal surgery. The aim of the present study was to investigate the incidence of EA in adults undergoing septoplasty and the effect of ketamine on EA. METHODS: In this randomized study, a total of 102 ASA I-II patients who underwent septoplasty between July 2018 and April 2019 were divided into two groups: ketamine (Group-K, n=52) and saline (Group-S, n=50). After anesthesia induction, Group-K was intravenously administered 20mL of saline containing 1mgkg-1 ketamine, whereas Group-S was administered 20mL of saline. Sedation and agitation scores at emergence from anesthesia, incidence of cough, emergence time, and response to verbal stimuli time were recorded. The sedation/agitation and pain levels were recorded for 30minutes in the recovery unit. RESULTS: There was no significant difference between the groups in terms of the incidence of EA (Group-K: 15.4%, Group-S: 24%). The incidence of cough during emergence was higher in Group-S than in Group-K, but the response time to verbal stimuli and emergence time were shorter in Group-S. The sedation and agitation scores were similar after surgery. Pain scores were higher in Group-S at the time of admission to the recovery unit and were similar between groups in the other time points. CONCLUSION: Administration of 1mgkg-1 ketamine after anesthesia induction does not affect the incidence of EA in patients undergoing septoplasty, but it prolongs the emergence and response time to verbal stimuli and reduces the incidence of cough.

Derivation and Validation of an Ensemble Model for the Prediction of Agitation in Mechanically Ventilated Patients Maintained Under Light Sedation.

OBJECTIVES: Light sedation is recommended over deep sedation for invasive mechanical ventilation to improve clinical outcome but may increase the risk of agitation. This study aimed to develop and prospectively validate an ensemble machine learning model for the prediction of agitation on a daily basis. DESIGN: Variables collected in the early morning were used to develop an ensemble model by aggregating four machine learning algorithms including support vector machines, C5.0, adaptive boosting with classification trees, and extreme gradient boosting with classification trees, to predict the occurrence of agitation in the subsequent 24 hours. SETTING: The training dataset was prospectively collected in 95 ICUs from 80 Chinese hospitals on May 11, 2016, and the validation dataset was collected in 20 out of these 95 ICUs on December 16, 2019. PATIENTS: Invasive mechanical ventilation patients who were maintained under light sedation for 24 hours prior to the study day and who were to be maintained at the same sedation level for the next 24 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 578 invasive mechanical ventilation patients from 95 ICUs in 80 Chinese hospitals, including 459 in the training dataset and 119 in the validation dataset, were enrolled. Agitation was observed in 36% (270/578) of the invasive mechanical ventilation patients. The stepwise regression model showed that higher body temperature (odds ratio for 1°C increase: 5.29; 95% CI, 3.70-7.84; p < 0.001), greater minute ventilation (odds ratio for 1 L/min increase: 1.15; 95% CI, 1.02-1.30; p = 0.019), higher Richmond Agitation-Sedation Scale (odds ratio for 1-point increase: 2.43; 95% CI, 1.92-3.16; p < 0.001), and days on invasive mechanical ventilation (odds ratio for 1-d increase: 0.95; 95% CI, 0.93-0.98; p = 0.001) were independently associated with agitation in the subsequent 24 hours. In the validation dataset, the ensemble model showed good discrimination (area under the receiver operating characteristic curve, 0.918; 95% CI, 0.866-0.969) and calibration (Hosmer-Lemeshow test p = 0.459) in predicting the occurrence of agitation within 24 hours. CONCLUSIONS: This study developed an ensemble model for the prediction of agitation in invasive mechanical ventilation patients under light sedation. The model showed good calibration and discrimination in an independent dataset.

The safety of early administration of oral fluid following general anesthesia in children undergoing tonsillectomy: a prospective randomized controlled trial.

BACKGROUND: The feasibility and safety of administrating a small amount of oral fluid to children in the early recovery period following tonsillectomy under general anesthesia to reduce the thirst and its associated restlessness remain unknown. METHODS: This study was approved by the institutional ethics committee and adhered to the CONSORT guidelines. Pediatric patients undergoing tonsillectomy who met the inclusion and exclusion criteria of our study were randomized into the study and control groups. In the study group, patients were given a small amount of water instantly after recovering from general anesthesia, which included the recovery of the cough and deglutition reflex, and attaining grade V of muscle strength. The control group was given a small amount of water at 4 to 6 h after the operation. The incidence of nausea and vomiting and the degree of thirst relief were measured and compared between the two groups. RESULTS: Three hundred patients were randomized into each group. There was no significant difference in the incidence of nausea and vomiting at 20 min after drinking water between the two groups (P > 0.05). The thirst score of children over 5 years old in the study group was significantly lower than that of the control group (P < 0.05). CONCLUSION: Early administration of a small amount of oral fluid to children following tonsillectomy and recovering from general anesthesia is not only safe but also effective in reducing postoperative thirst.

Testing the Impact of FFC-AL-EIT on Psychosocial and Behavioral Outcomes in Assisted Living.

BACKGROUND: This study tested the impact of Function Focused Care for Assisted Living Using the Evidence Integration Triangle (FFC-AL-EIT) on: (1) care interactions between residents and direct care staff; and (2) behavior and psychological symptoms associated with dementia among residents. DESIGN: This was a randomized controlled trial. SETTING: A total of 59 assisted living facilities in Maryland, Pennsylvania, and Massachusetts participated. PARTICIPANTS: The sample included 550 mostly White (98%), female (69%) residents with a mean age of 89.30 (standard deviation = 7.63) years. INTERVENTION: The four-step FFC-AL-EIT intervention was implemented by a function focused care nurse facilitator working with a facility champion over 12 months. The steps included: (1) environment and policy assessments; (2) education; (3) establishing resident function focused care service plans; and (4) mentoring and motivating. MEASURES: Resident descriptive data (e.g., age, sex, education, and comorbidities), depression, agitation, resistiveness to care, and the quality of care interactions were obtained at baseline and 4 and 12 months. Treatment fidelity data included environment and policy assessments, performance of function focused care by staff, and service plan assessments. RESULTS: There was a significant positive treatment effect related to depression, agitation, resistiveness to care, and quality of care interactions with either less decline or some improvement in these behaviors and symptoms in the treatment versus control group. CONCLUSION: The study provides some statistical support, which may not necessarily be clinically significant evidence, for psychosocial outcomes of residents and care interactions between staff and residents in assisted living settings.

Impact of Early Reinitiation of Neuropsychiatric Medications on Agitation and Delirium in the Intensive Care Unit: A Retrospective Study.

BACKGROUND: Approximately 17% of intensive care unit (ICU) patients are prescribed at least 1 home neuropsychiatric medication (NPM). When abruptly discontinued, withdrawal symptoms may occur manifesting as agitation or delirium in the ICU setting. OBJECTIVE: To evaluate the impact of early reinitiation of NPMs. METHODS: This was a retrospective, observational cohort of adult ICU patients in a tertiary care hospital. Patients were included if admitted to the ICU and prescribed a NPM prior to arrival. Study groups were based on the timing of reinitiation of at least 50% of NPMs: ≤72 hours (early group) versus >72 hours (late group). RESULTS: The primary outcome was the proportion of patients with at least 1 agitation or delirium episode in the first 72 hours. Agitation and delirium were defined as at least 1 RASS assessment between +2 to +4 and a positive CAM-ICU assessment, respectively. A total of 300 patients were included, with 187 (62%) and 113 (38%) in the early and late groups, respectively. There was no difference in agitation or delirium (late 54 [48%] vs early 62 [33%]; adjusted odds ratio [aOR] = 1.5; 95% CI = 0.8-2.8; P = 0.193). Independent risk factors found to be associated with the primary outcome were restraints (aOR = 12.9; 95% CI = 6.9-24.0; P < 0.001) and benzodiazepines (BZDs; aOR = 2.0; 95% CI = 1.0-3.7; P = 0.038). CONCLUSIONS: After adjustment for baseline differences, there was no difference in agitation or delirium. Independent risk factors were restraint use and newly initiated BZDs.
