Rapid tranquilization of the agitated patient in the emergency department: A systematic review and network meta-analysis.

Safe and effective tranquilization of the acutely agitated patient is challenging, and head-to-head comparisons of medications are limited. We aimed to identify the most optimal agent(s) for rapid tranquilization of the severely agitated patient in the emergency department (ED). The protocol for systematic review was registered (PROSPERO; CRD42020212534). We searched MEDLINE, Embase, PsycINFO, and Cochrane Database/CENTRAL from inception to June 2, 2021. We limited studies to randomized controlled trials that enrolled adult ED patients with severe agitation and compared drugs for rapid tranquilization. Predetermined outcomes were: 1) Adequate sedation within 30min (effectiveness), 2) Immediate, serious adverse event - cardiac arrest, ventricular tachydysrhythmia, endotracheal intubation, laryngospasm, hypoxemia, hypotension (safety), and 3) Time to adequate sedation (effect onset). We extracted data according to PRISMA-NMA and appraised trials using Cochrane RoB 2 tool. We performed Bayesian network meta-analysis (NMA) using a Markov Chain Monte Carlo method with random-effects model and vague prior distribution to calculate odds ratios with 95% credible intervals for dichotomous outcomes and frequentist NMA to calculate mean differences with 95% confidence intervals for continuous outcomes. We assessed confidence in results using CINeMA. We used surface under the cumulative ranking (SUCRA) curves to rank agent(s) for each outcome. Eleven studies provided data for effectiveness (1142 patients) and safety (1147 patients). Data was insufficient for effect onset. The NMA found that ketamine (SUCRA=93.0%) is most likely to have superior effectiveness; droperidol-midazolam (SUCRA=78.8%) is most likely to be safest. There are concerns with study quality and imprecision. Quality of the point estimates varied for effectiveness but mostly rated "very low" for safety. Available evidence suggests that ketamine and droperidol have intermediate effectiveness for rapid tranquilization of the severely agitated patient in the ED. There is insufficient evidence to definitively determine which agent(s) may be safest or fastest-acting. Further, direct-comparison study of ketamine and droperidol is recommended.

The Pharmacokinetics of Drug Delivery to the Upper Nasal Space: A Review of INP105 Development

Nasal drug delivery presents a potential opportunity for achieving rapid, extensive drug absorption via a nonoral route by 1) avoiding degradation within the gastrointestinal tract and first-pass metabolism in the liver and 2) facilitating faster onset via rapid absorption into the bloodstream. However, the site of drug deposition within the nasal cavity may impact drug pharmacokinetics. Precision Olfactory Delivery (POD®) by Impel Pharmaceuticals Inc. is a new technology that provides handheld, manually actuated, propellant-powered drug delivery to the upper nasal space for rapid and efficient absorption. Rapid onset of effect can be a major advantage in many clinical applications where quick and effective administration is needed (eg, alleviating agitation in emergency settings or reducing debilitating migraine symptoms). Here, we review the pharmacokinetic profile of INP105, which is being developed to deliver olanzapine (OLZ) by POD to treat agitation in patients with autism. Because formulation can play a large role in the pharmacokinetic profile of a nasally administered drug, we provide a comprehensive review of both published and previously unpublished preclinical data outlining how the INP105 formulation was developed and optimized for study in humans. Multiple formulation carriers and excipients were tested to find a stable INP105 formulation with a desirable nasal absorption profile. Because the nasal architecture in nonhuman primates (NHPs) is similar to humans, the pharmacokinetics and tolerability of an INP105 combination product (NHP-INP105) using a clinical formulation combined with a device specifically designed for NHPs has been investigated in preclinical NHP studies, providing translational data for human studies and the pathway for testing novel products and formulations. The pharmacokinetics and tolerability of INP105 were then evaluated in an early clinical study in humans, demonstrating favorable pharmacokinetic and pharmacodynamic profiles. In this review, we aim to illustrate how delivery of therapeutics to the upper nasal space using POD, such as with agents like INP105, has the potential to optimize nasal delivery and unlock the potential of delivery-limited drugs to provide patients with rapid onset of effect, ease of use, and convenience.

Effect Evaluation of Dexmedetomidine Intravenous Anesthesia on Postoperative Agitation in Patients with Craniocerebral Injury by Magnetic Resonance Imaging Based on Sparse Reconstruction Algorithm.

The effect of dexmedetomidine on postoperative agitation of patients with craniocerebral injury was investigated based on magnetic resonance imaging (MRI) with the sparse reconstruction algorithm. Sixty patients with craniocerebral injury who underwent tracheal intubation and craniotomy hematoma removal under general anesthesia in hospital were selected as the research objects. Patients were randomly and averagely divided into the normal saline group (group A) and the dexmedetomidine (DEX) group (group B). DEX was added to patients in group A during anesthesia. Other operations in group B were the same as those in group A, where DEX needed to be used was replaced by an equal amount of the normal saline. All patients received the MRI examination, and the images were processed by using the sparse reconstruction algorithm. After the surgery, some indexes, such as hemodynamics (mean arterial pressure (MAP) and hear rate (HR)), the Riker sedation agitation score, the Ramsay sedation score, and the visual analogue scale (VAS) score were recorded and compared. The results showed that the MRI image quality processed by sparse reconstruction algorithm was observably improved. After reconstruction, the sharpness of the image was significantly improved, and the distinction between lesions and tissues was also increased. The Riker sedation agitation score and the incidence of agitation in group A were greatly lower than those in group B (16% VS 76%, P < 0.05). The Ramsay sedation score of group A was manifestly higher than that of group B. The cases of postoperative nausea, vomiting, chills, delirium, and bradycardia in group A were 2, 1, 1, 0, and 1, respectively. The cases of postoperative nausea, vomiting, chills, delirium, and bradycardia in group B were 3, 9, 6, 5, and 0, respectively. The cases of chills and delirium in group A were observably less than those in group B (P < 0.05). In conclusion, based on the sparse reconstruction algorithm, the MRI technology and DEX had high adoption value in preventing postoperative agitation of patients with craniocerebral injury. Compared with group B, the hemodynamics of patients in group A was more stable.

"White code protocol": model of interprofessional collaboration in the emergency room

Acute agitation is a frequent cause of emergency department's consultation. Managing an agitated patient is complex due to many factors and require from healthcare teams a close interdisciplinary collaboration. Scope of this article is to describe the management of agitated patients in an emergency department and to present an interprofessional medical care protocol (white code protocol), giving also the opinion of principal actors of this healthcare interdisciplinary model.

A Model Program to Manage Behavioral Emergencies and Support Nurses in the Medical Setting.

Medically hospitalized individuals have high rates of comorbid psychiatric, substance abuse, and behavioral disorders. Disruptive and sometimes aggressive behaviors may arise when mental health needs of patients go unrecognized or are inadequately addressed. Health care workers experience the most workplace violence compared with other professions, with nurses and nursing aides at highest risk. A Behavioral Emergency Support Team (BEST) model can be an effective approach to providing a customized response to a patient's agitation through identification of underlying clinical and environmental contributors to the onset of aggression as well as to provide behavioral education and support of nursing staff. Results from 2 years of BEST model use resulted in 124 events among 96 patients of whom 19 had repeated events. The most common reasons for codes were aggression (79%) and elopement threat/attempt (45%), and the most frequent patient diagnosis was cognitive impairment (54%). Development of a BEST model provides support to nurses that is not otherwise available for events that are disruptive to care in inpatient medical settings and help minimize the occurrence of workplace violence.

Continuous intrathecal infusion for refractory pain management in an oncologic patient in intensive care

Adult patients in the intensive care unit (ICU) often experience pain resulting from acute and chronic illness, as well as from standard positioning and maneuverers in the ICU. In recent years, the need for effective pain control in intensive care has emerged strongly. Partial or ineffective control is associated with multiple complications, such as agitation, delirium, inability to adapt to mechanical ventilation, increased length of stay, and post-traumatic stress disorder. Recent guidelines and studies suggest multimodal strategies for effective pain control, also re-evaluating the use of locoregional anesthesiological techniques. Oncological pain in critically ill patients represents a particular challenge for medical staff, being closely linked to the concept of palliative care. We present a case of refractory pain and agitation in an oncologic patient following an emergency exploratory laparotomy. Through the use of an intrathecal catheter, we provided effective analgesia to control pain and agitation, allowing weaning from mechanical ventilation before, and once the terminal state of the tumor was established, providing palliative care to ensure dignity and satisfaction of the patient.

Evaluating the impact of an emergency department protocol that guides management of methamphetamine-induced agitation and psychosis.

BackgroundMethamphetamine is an addictive stimulant that may induce symptoms of agitation and psychosis. The estimated rate of methamphetamine use is 6.6 per 1000 people. Currently, no treatment guidelines exist to support the optimal management of patients presenting with methamphetamine-induced agitation. Emergency department (ED) providers may prescribe various benzodiazepines (BZDs) and antipsychotics (APs) as first-line agents to stabilize these agitated patients. This study aims to determine the effectiveness of a protocol to guide management of this condition.MethodsThis was a retrospective, pre- and poststudy conducted from July 2020 to March 2021 at a large academic medical center. A multidisciplinary protocol was designed to help manage methamphetamine-induced agitation in the ED. The primary outcome of the study was a reduction in the number of BZDs and APs used for the treatment of methamphetamine-induced agitation. This was measured by the incidence of overprescribing, defined as 3 or more APs or BZDs administered within 30 minutes. Secondary outcomes included the use of physical restraints, ED length of stay, and adverse events.ResultsWe did not observe a significantly lower incidence of overprescribing, adverse events, or ED length of stay when comparing pre- and postprotocol groups. A subgroup analysis demonstrated that when protocol was followed, there was a statistically significant reduction in overprescribing (P = .001).DiscussionWe did not find any differences among our primary and secondary outcomes, which may be attributed to protocol nonadherence. Full compliance to the protocol may reduce the rate of overprescribing APs or BZDs in patients with methamphetamine-induced agitation.

К источникам мотива массового психоза в романе М.А. Булгакова «Мастер и Маргарита»

The aim of the work is to analyze the motive of mass psychosis in the novel “Master and Margarita” by M.A. Bulgakov. It is relevant nowadays, when the tendency of close study of madness motive in the writer's works as a particular case of madness motive in Russian literature is outlined in literary criticism. The subject of the research is the consideration of this motive as a technique of parody, creating a unique satirical palette of the sociopolitical life of the country in the era of 1920–1930. Therefore, the methodology of the article includes, along with traditional historical, cultural and mythopoetic approaches, a psychographic commentary. As a result, sources from various humanitarian spheres of human activity are involved in the analysis: fiction, historiography, cultural studies, religion, and psychiatry. Among them: a methodological guide to organizing mass singing “Mass Feasts” (1927) by E.F. Ryumin, , the history of burials in the Vagankovo Cemetery “Men of the Forties” (1869), the novel by A.F. Pisemsky and the related ideology of early twentieth-century literary movements (Symbolism and Proletkult), I.S. Lukash’s emigrant novel “Devil” (1922), a journal version of N. Ognev’s (M. G. Rozanov) novel “Diary of Kostya Ryabtsev” (1926–1928), work by English religion historian D. Robertson “Primordial Christianity” (Russian translation 1930), and N. Kalashnikov’s essay “The Count Cagliostro, the Sorcerer of the Last Century” (1893). Particular emphasis is placed on the psychiatric practice of subduing violent patients. It is concluded that to recreate the motive of mass hysteria Bulgakov’s parody goes from high to low, from laughter to a stamp of horror on the face.

Are non-pharmacological interventions for patient agitation in ICU effective?

Introduction: There are major concerns related to an overreliance on pharmacological interventions and physical restraints for patient agitation. However, person-centred non-pharmacological interventions to prevent and manage agitation in the intensive care unit are not well understood.

A Novel Simulation-Based Multidisciplinary Verbal De-escalation Training.

BackgroundAgitated or aggressive patients pose a high risk of emotional and physical harm to hospital staff. Healthcare associates have the highest rate of workplace violence among studied fields. Learning to effectively de-escalate a patient who is a danger to self or others is key to reducing these incidents. This course was designed to improve education and communication among staff on a hospital surgical floor when verbal de-escalation is needed.MethodsA ninety-minute simulation-based multidisciplinary curriculum was developed. This included a 30-minute didactic discussion, 10-minute simulation, and 50-minute debrief. Learners included nurses, patient service associates, and protective services officers from a medical/surgical unit. Data were collected using a validated return on investment in learning protocol and the Management of Aggression and Violence Attitude Scale (MAVAS) tool.ResultsOur return on investment in learning showed that more than 97% of learners felt safer in managing agitated patients after participating in the training. The MAVAS tool was used in pre- and post-format and showed a significant trend toward the importance of clear communication and role clarity when de-escalating a patient.ConclusionsA combination of didactic teaching and simulated experience allowed for greater confidence, communication, and teamwork in de-escalating an agitated patient in a community hospital surgical unit.

Treating Agitation in Patients with Dementia with a Therapy Dog in a Milieu Therapy Setting on a Geropsychiatric Ward

Background: Animal-assisted intervention has become a common therapeutic practice used for patients with dementia in home-dwelling and institutions. The most established procedure is a visiting service by specially trained dogs and their owners to improve social interactions and reduce symptoms of agitation. Objectives: The study aims to investigate the effects of a therapy dog on agitation of inpatients with dementia in a gerontopsychiatric ward. Materials and Methods: The severity of agitation was assessed by a rater blinded for the presence of the dog via the Overt Agitation Severity Scale (OASS). The scale was conducted on 1 day with the dog and his handler present (resident doctor on the ward) and on another day with only the handler present. Each patient was his/her own control. Heart rate variability (HRV) and serum level of brain-derived neurotrophic factor (BDNF) of the patients were measured on both days. 26 patients with the Mini-Mental Status Examination (MMSE) score <21 and the diagnosis of dementia were included in the study. Results: A significant reduction of agitation in the OASS could be shown when the dog was present (p = 0.006). The data neither demonstrated a difference in the HRV for the parameters mean heart rate (p = 0.65), root mean square of successive differences (p = 0.63), and high frequencies (p = 0.27) nor in serum BDNF concentrations (p = 0.42). Discussion: Therapy dogs can be implemented as a therapeutic tool in a gerontopsychiatric ward to reduce symptoms of agitation in patients with dementia. The study was registered in the German Clinical Trials Register (DRKS00024093).

The role of experiential knowledge in hospital nurses’ management of pain-related agitation in people with dementia: An expert performance simulation study

BackgroundPain-related agitation in hospital patients with dementia presents a diagnostic challenge as patients often cannot explain their agitation. Generally, a deductive process is required of staff, culminating in an analgesic trial. However, evidence suggests the deductions of hospital nurses may be flawed because they may not associate agitation in dementia with painful conditions, thereby missing key clinical cues. While analytical rule-based deduction applies explicit formal knowledge, cognitive scientists argue that tacit experiential knowledge, i.e., the unconscious classification of available cues, is equally important and is always involved. AimTo identify the cognitive characteristics unique to nurses who accurately recognise pain-related agitation in a patient with dementia compared with nurses who do not. MethodsIn this descriptive multivariate study, registered acute-care nurses undertook an original computerised virtual simulation requiring them to identify and manage pain-related agitation in a standardised patient with dementia. Process tracing methods captured nurses’ simulation performances alongside their retrospective accounts of thinking. These were correlated with demographic characteristics related to seniority, workplace, training, experience and knowledge captured on a questionnaire. Dual processing theory enabled interpretation of intuitive and analytical cognitive processes. FindingsRegistered medical and surgical nurses (N = 274) participated from 10 hospitals. Although formal knowledge about pain in dementia was high (88%), only 13(4.7%) nurses identified pain-related agitation from an injury. These individuals took the longest and used the most cues, undertaking a detailed deductive search. Their recognition of pain-related cues demonstrated accurate experiential knowledge while another 16 nurses identified a fracture without linking the injury to agitation. Over three quarters (78%) of nurses decided on initial antipsychotic treatment. They were quick to decide, using the fewest cues, suggesting agitation was recognised as typical and familiar, with the solution well-known (albeit ineffective). Independent of other variables, nurses working in dementia-specific units, surgical units or with more seniority had increased odds of recognising pain, revealing the influence of workplace experience. However, most surgical and dementia-unit nurses did not recognise pain. ConclusionsHospital nurses have difficulty recognising when agitation in a patient with dementia is caused by pain. High formal knowledge about pain in dementia may not be sufficient to enable clinical recognition of pain in patients. Instead, nurses with experience in specific workplaces or senior roles may be better equipped to recognise pain-related agitation and deploy evidence-based approaches for agitation in a patient with dementia. Overall, these results lend support to the influence of experiential knowledge on performance. Tweetable abstractIn a virtual simulation, registered nurses with high formal knowledge about pain in dementia lacked the experience required to recognise pain-related agitation in a patient with dementia

Self-Reported Violence Experienced by Swiss Prehospital Emergency Care Providers.

Background Workplace violence is a serious and increasing problem in health care. Nevertheless, only few studies were carried out concerning this topic and then mainly in English-speaking countries. The objectives were to describe the acts of violence experienced by prehospital emergency care providers (PECPs) in the western part of Switzerland between January and December 2016 and to assess the consequences for subsequent PECPs behaviors. Methods An observational cross-sectional study, carried out using an online survey, has been sent to all 416 PECPs in the Canton of Vaud, in the western, French-speaking, part of Switzerland. The survey contained items of demographic data and items to assess the type and consequence of violence sustained. This was classified as five types: verbal assault, intimidation, physical assault, sexual harassment, and sexual assault. Results 273 (65.6%) PECPs participated in the survey. During 2016, workplace violence was reported by 229 survey participants (83.9%). Most declared to be the victim of such violence between one and three times during the year. In all cases of violence described, the patient and/or a relative initiated aggressive behavior in 96% of cases. Verbal assaults were the most common (99.2% of all acts), followed by intimidation (72.8%), physical assault (69.6%), and sexual harassment (16.3%). Concerning physical assault, PECPs were predominantly victims of spitting and/or jostling (50%). After a violent event, in 50% of cases, the PECPs modified their behavior owing to the experience of workplace violence; 82% now wear protective vests, and 16% carry weapons for self-defense, such as pepper sprays. Seventy-five percent changed their intervention strategies, acting more carefully and using verbal de-escalation techniques or physical restraints for violent patients. Conclusions Workplace violence is frequent and has significant consequences for PECPs. In order to increase their own security, they increased their protection. These results illustrate their feelings of insecurity, which may have deleterious effects on work satisfaction and motivation. Trial Registration.

Validation of Agitated Patient Remote Monitoring Alarm System in the Intensive Care Unit.

The purpose of this research is to innovate and develop a vision-based remote monitoring alarm system for agitated patients to provide intensive care unit (ICU) nurses with action warnings for agitated patients during their busy work. After the system is completed, preliminary laboratory verification is carried out, and the results are 94.87% in sensitivity, 97.44% in specificity, and 96.15% in accuracy, which enhances the confidence of the follow-up system in clinical testing.

Effect of Different Anesthesia Methods on Emergence Agitation and Related Complications in Postoperative Patients with Osteosarcoma.

Purpose To explore the effect of different anesthesia methods on emergence agitation (EA) and related complications in postoperative patients with osteosarcoma. Methods According to the order of admission, 115 patients requiring osteosarcoma surgery treated in our hospital from January 2018 to December 2020 were selected as the research object and randomly divided into the control group (n = 57, accepted the general anesthesia with tracheal intubation) and the experimental group (n = 58, accepted the combined spinal-epidural anesthesia) to compare their anesthesia effect, incidence rates of agitation and complications, and other indexes. Results In terms of the hemodynamic indexes (MAP, HR, and CVP values), both groups had lower ones at T1 than at T0, but the decline of the experimental group was generally lesser than that of the control group; at T2, no statistical difference was shown within the experimental group's indexes when comparing with those at T1, but the control group obtained a significant increase; at T3 and T4, both groups had their hemodynamic indexes increased, but such increase within the experimental group showed no statistical difference when comparing with those at T0, while the control group achieved obviously higher values at T4 than at T0 (before the anesthesia); and the between-group difference in the hemodynamic indexes at T1 and T4 was significant. Compared with the control group, the experimental group achieved better VAS scores and anesthesia indexes and lower incidence rates of EA and complications such as the hypoxemia, cardiovascular response, delayed recovery, and headache. In addition, the differences in the incidence rates of hypotension and cognitive dysfunction between the two groups were not statistically significant. Conclusion When comparing with tracheal intubation general anesthesia, the combined spinal-epidural anesthesia has a better effect in osteosarcoma surgery, with less hemodynamics influence on patients, reduced postoperative pain and stress reaction, and lowered incidence rates of postoperative EA and complications, which is worthy of wide application in clinical treatment.

The effects of intraoperative magnesium sulfate administration on emergence agitation and delirium in pediatric patients: A systematic review and meta-analysis of randomized controlled trials.

The role of intraoperative magnesium for the prevention of emergence agitation or delirium is unclear as there have been conflicting results reported by several randomized controlled trials. The aim of this study was to investigate the effect of magnesium sulfate on emergence agitation or emergence delirium in pediatric patients. Electronic databases, including PubMed, EMBASE, CENTRAL, CINAHL, Scopus, and Web of Science, were searched to identify studies which evaluated the effects of magnesium on postoperative emergence agitation or emergence delirium. The primary outcome was the incidence of emergence agitation or emergence delirium during the post-anesthesia stay. The secondary outcome was the agitation or delirium score upon admission to the post-anesthesia care unit. We estimated the odds ratio and standardized mean difference using a random-effect model. A total of 712 pediatric patients from 10 randomized controlled trials were included in the final analysis. The incidence of emergence agitation or emergence delirium was 29.7% in the magnesium group and 50.5% in the control group. The pooled effect size revealed that the administration of magnesium sulfate significantly reduced the incidence of postoperative emergence agitation or emergence delirium in pediatric patients undergoing surgery with general anesthesia (Odds ratio, 0.31; 95% confidence interval, 0.15 to 0.64; p=.002). Additionally, children in the magnesium group reported significantly lower agitation or delirium scores than those in the control group (standardized mean difference, -0.70; 95% confidence interval, -1.15 to -0.24; p=.003). The administration of magnesium sulfate reduced the incidence and severity of emergence agitation or emergence delirium in pediatric patients after the use of general anesthesia during surgery.
