Influence of Age and Sex on the Pharmacokinetics of Midazolam and the Depth of Sedation in Pediatric Patients Undergoing Minor Surgeries. Pharmaceutics 2023; 15:pharmaceutics15020440. [PMID: 36839762 PMCID: PMC9963644 DOI: 10.3390/pharmaceutics15020440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 12/23/2022] [Accepted: 01/09/2023] [Indexed: 02/03/2023] Open
Abstract
Whether age and sex influence the depth of sedation and the pharmacokinetics of midazolam is currently unknown. The influence of age and sex was investigated in 117 children (2 to 17 years) who required intravenous sedation for minor surgery (0.05 mg/kg). Plasma concentrations and sedation effects were simultaneously measured. The measured concentrations were analyzed using a two-compartment model with first-order elimination. Among the age ranges, significant differences were found (p < 0.05) between the volume of distribution (Vd) of the first compartment (V1) and that of the second (V2). With respect to sex, differences in V2 were found between age groups. At the administered dose, in patients younger than 6 years, a profound sedative effect (40-60 BIS) was observed for up to 120 min, while in older children, the effect lasted only half as long. The differences found in the Vd and bispectral index (BIS) in patients younger than 6 years compared to older patients may be due to immature CYP3A activity and body fat content; furthermore, the Vd varies with age due to changes in body composition and protein binding. Patients younger than 6 years require intravenous (IV) doses <0.05 mg/kg of midazolam for deep sedation. Dosage adjustments according to age group are suggested.

Abstract
Patients who suffer from dyspnea while dying from COVID-19 are treated with opioids and benzodiazepines. In some instances, patients may experience refractory dyspnea at the end of life. Palliative sedation can be prescribed to alleviate such patients' suffering. We describe two patients being treated for severe COVID-19 pneumonia in a tertiary hospital. Both developed intractable dyspneic crises despite high-dose opioids and benzodiazepines. This led to their requirement of palliative sedation in the general ward using subcutaneous phenobarbitone (phenobarbital). We outline clinical considerations for the use of palliative sedation in COVID-19 related dyspnea. In particular, we discuss the evidence for, benefits and limitations of using phenobarbitone for palliative sedation in COVID-19 patients.

Indian J Anaesth 2022; 66:687-693. [PMID: 36437979 PMCID: PMC9698290 DOI: 10.4103/ija.ija_340_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2022] [Revised: 10/05/2022] [Accepted: 10/07/2022] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND AND AIMS Sedation in paediatric cancer for fractionated radiation treatment (RT) is unique as the child has to be still for accurate delivery of RT, monitoring of the child is from a remote location and sedation is repeated for multiple sessions of RT. The present study was undertaken to compare the efficacy of intranasal dexmedetomidine with oral midazolam and ketamine combination for repeated sedation during fractionated RT in paediatric oncology. METHODS Ninety children aged between 3-6 years, planned for 21 fractions of RT, were randomised to receive intranasal dexmedetomidine 2 μg/kg (group D) or oral midazolam 0.2 mg/kg and ketamine 5 mg/kg (group MK). The 21 sessions of fractionated radiotherapy were divided into three subgroups of seven consecutive exposures 1-7, 8-14 and 15-21 for comparison. The primary endpoint was to determine the incidence of successful sedation. The sedation score achieved, time to satisfactory sedation and discharge, rescue ketamine required, and side effects were secondary endpoints. RESULTS The incidence of successful sedation in the three successive RT subgroups; sessions: 1-7, 8-14 and 15-21, was 82%, 75.6% and 66.7% in group D, as compared to 40%, 24.4% and 13.3% in group MK, respectively. (P < 0.001). A decrease in successful sedation was noted in the successive subgroups. Time to successful sedation and discharge was earlier in group D in comparison to MK (P = 0.000). More patients in group MK required rescue ketamine (P = 000). CONCLUSION Intranasal dexmedetomidine produces more satisfactory sedation as compared to oral ketamine with midazolam for fractionated RT.

Abstract
Midazolam (MDZ) is a short-acting benzodiazepine that is widely used to induce and maintain general anesthesia during diagnostic and therapeutic procedures in pediatric patients due to its sedative properties. The aim of this study was to perform a systematic review without a meta-analysis to identify scientific articles and clinical assays concerning MDZ-induced sedation for a pediatric surgery approach. One hundred and twenty-eight results were obtained. After critical reading, 37 articles were eliminated, yielding 91 publications. Additional items were identified, and the final review was performed with a total of 106 publications. In conclusion, to use MDZ accurately, individual patient characteristics, the base disease state, comorbidities, the treatment burden and other drugs with possible pharmacological interactions or adverse reactions must be considered to avoid direct alterations in the pharmacokinetics and pharmacodynamics of MDZ to obtain the desired effects and avoid overdosing in the pediatric population.

Abstract
BACKGROUND Providing unawareness and pain relief are core elements of palliative sedation. In addition to clinical scales, nociception and electroencephalogram-based depth of sedation monitoring are used to assess the level of consciousness and analgesia during sedation in intensive care units and during procedures. AIM To determine whether reported devices impact the outcomes of palliative sedation. DESIGN Systematic review and narrative synthesis of research published between January 2000 and December 2020. DATA SOURCES Embase, Google Scholar, PubMed, CENTRAL, and the Cochrane Library. All reports describing the use of any monitoring device to assess the level of consciousness or analgesia during palliative sedation were screened for inclusion. Data concerning safety and efficacy were extracted. Patient comfort was the primary outcome of interest. Articles reporting sedation but that did not meet guidelines of the European Association for Palliative Care were excluded. RESULTS Six reports of five studies were identified. Four of these were case series and two were case reports. Together, these six reports involved a total of 67 sedated adults. Methodological quality was assessed fair to good. Medication regimens were adjusted to bispectral index monitoring values in two studies, which found poor correlation between monitoring values and observational scores. In another study, high nociception index values, representing absence of pain, were used to detect opioid overdosing. Relatives and caregivers found the procedures feasible and acceptable.

Abstract
Background Palliative sedation has been used to refer to the practice of providing symptom control through the administration of sedative drugs. The objective of this article was to characterise palliative sedation use in inpatients at a medium-stay palliative care unit. Material and methods A cross-sectional study was conducted on 125 randomly selected patients (aged 15 or older) who had died in 2014. The Palliative Performance Scale was used to evaluate the functional status. Results Palliative sedation was documented in 34.4% of the patients and midazolam was the most commonly used sedative agent (86.0%). More than half (53.5%) of those who recieved sedation presented with delirium. Liver dysfunction was more frequent in the sedated patients (p=0.033) and patients with heart disease were less likely (p=0.026) to be sedated. Conclusion Palliative sedation is an ethically accepted practice. It was commonly midazolam-induced, and differences were documented, among sedated and non-sedated patients, in terms of liver dysfunction and heart disease.

Abstract
BACKGROUND The anesthetic propofol is often mentioned as a drug that can be used in palliative sedation. The existing literature of how to use propofol in palliative sedation is scarce, with lack of information about how propofol could be initiated for palliative sedation, doses and treatment outcomes. AIM To describe the patient population, previous and concomitant medication, and clinical outcome when propofol was used for palliative sedation. METHODS A retrospective study with quantitative and qualitative data. All patients who during a 4.5-year period received propofol for palliative sedation at the Department of palliative medicine, Akershus University Hospital, Norway were included. RESULTS Fourteen patients were included. In six patients the main indication for palliative sedation was pain, in seven dyspnoea and in one delirium. In eight of these cases propofol was chosen because of the pharmacokinetic properties (rapid effect), and in the remaining cases propofol was chosen because midazolam in spite of dose titration failed to provide sufficient symptom relief. In all patients sedation and adequate symptom control was achieved during manual dose titration. During the maintenance phase three of 14 patients had spontaneous awakenings. At death, propofol doses ranged from 60 to 340 mg/hour. CONCLUSIONS Severe suffering at the end of life can be successfully treated with propofol for palliative sedation. This can be performed in palliative medicine wards, but skilled observation and dose titration throughout the period of palliative sedation is necessary. Successful initial sedation does not guarantee uninterrupted sedation until death. EDITORIAL COMMENT In palliative care, some patients at the end of life can reach a stage where there have been maximal analgesic and or anxiolytic treatments though without achieving comfort in the awake state. This report describes and discusses use of propofol in these infrequent cases to relieve suffering as part of palliative care.

Abstract
BACKGROUND French legislation about sedation in palliative medicine evolved in 2016 with the introduction of a right to deep and continuous sedation, maintained until death. The objective was to describe midazolam sedation at the COL (Centre Oscar Lambret [Oscar Lambret Center], French regional center for cancer control), in order to establish a current overview before the final legislative changes. METHODS Descriptive, retrospective and single-center study, concerning major patients in palliative care hospitalized from 01/01/2014 to 12/31/2015, who had been sedated by midazolam. The proven sedations (explicitly named) and the probable sedations were distinguished. RESULTS A total of 54 sedations were identified (48 proven, 6 probable). Refractory symptoms accounted for 48.1% of indications, complications with immediate risk of death 46.3%, existential suffering 5.6%. Titration was performed in 44.4% of cases. Sedation was continuous until death for 98.1% of the cases. Probable sedation had a higher failure rate than proven sedation. Significant differences existed for the palliative care unit compared to other units regarding information to the patient, their consent, anticipation, mention by correspondence and carrying out titrations. When patients had already been treated with midazolam, the induction doses, initial maintenance doses, and doses at the time of death were significantly higher. For those receiving opioids, the maintenance dose at the time of death was higher. No comparison found a difference in overall survival. CONCLUSIONS After a sufficient follow-up has enabled teams to familiarize with this new legislation, reflection on sedation should be conducted to adapt to final recommendations.

Abstract
Palliative sedation (PS) is performed in the terminally ill patient to manage one or more refractory symptoms. Proportional PS, which means that drugs can be titrated to the minimum effective dose, is the form most widely used. From a quarter to a third of all terminally ill patients undergo PS, with a quarter of these requiring continuous deep sedation. The prevalence of PS varies according to the care setting and case mix. The most frequent refractory physical symptoms are delirium and dyspnea, but PS is also considered for existential suffering or psychological distress, which is an extremely difficult and delicate issue to deal with. Active consensus from the patient and advanced care planning is recommended for PS. The decision-making process concerning the continuation or withdrawal of other treatments is not the same as that used for PS. The practice differs totally from euthanasia in its intentions, procedures, and results. The most widely used drugs are midazolam and haloperidol for refractory delirium, but chlorpromazine and other neuroleptics are also effective. In conclusion, some patients experience refractory symptoms during the last hours or days of life and PS is a medical intervention aimed at managing this unbearable suffering. It does not have a detrimental effect on survival.

Abstract
BACKGROUND Pathophysiological changes at the end of life may affect pharmacokinetics of drugs. However, caregivers typically do not extensively monitor patients' laboratory parameters at the end of life. OBJECTIVE Our aim was to describe laboratory parameters of hospice patients in the week before death. METHODS A cohort study was conducted on available laboratory results in the week before death, including clinical chemistry and hematology tests. RESULTS Laboratory data of 125 patients in a palliative care center were included, assessed at a median of 3 days before death. Eighty percent of patients had anemia and almost all had hypoalbuminemia (97%). Elevated levels of gamma-glutamyl transferase (gGT) were found in 75%, of alkaline phosphatase (ALP) in 60%, of aspartate aminotransferase (ASAT) in 60%, and of calcium (Ca) in 68%. Alanine aminotransferase (ALAT), bilirubin, sodium (Na), and potassium (K) were abnormal in from 8.8% to 36.0% of patients. A previous unknown poor kidney function was found in 60% of patients. Thirteen patients (22%) with a regular morphine prescription and one patient treated with a non-steroidal anti-inflammatory drug (NSAID) had severe kidney failure. CONCLUSIONS Abnormal laboratory results were expected due to the pathophysiological changes that occur during the last phase of life. Remarkably, however, electrolytes (Na and K) were balanced even shortly before death. Estimated glomerular filtration rate (eGFR), reflecting the kidney function, seems the most clinically relevant laboratory parameter, because it may guide drug choice and dosing.

Abstract
OBJECTIVES Controlling seizures in children approaching death can be difficult, and there is a limited evidence base to guide best practice. We compared current practice against the guidance for seizure management produced by the Association of Paediatric Palliative Medicine (APPM). METHODS Retrospective case note review of episodes of challenging seizure management in children receiving end-of-life care over a 10-year period (2006-2015) in the south-west region of England. RESULTS We reviewed 19 admissions, in 18 individuals. Six (33%) had a malignancy, nine (50%) had a progressive neurodegenerative condition and three (17%) had a static neurological condition with associated epilepsy. Thirteen (72%) died in their local hospice, four (22%) at home, and one (6%) in hospital. Seventeen of 19 episodes involved the use of subcutaneous or intravenous midazolam infusion, for a mean of 11 days (range 3-27). There was a wide range of starting doses of midazolam, and 9/17 (53%) received final doses in excess of current dose recommendations. Six individuals received subcutaneous phenobarbital infusions, with four of these (67%) receiving final doses in excess of current dose recommendations. Plans for adjustments of infusion rates, maximal doses or alternative approaches should treatment fail were inconsistent or absent. In 16/18 (88%) cases seizures were successfully controlled prior to the day of the child's death. Staff found the experience of managing seizures at end of life challenging and stressful. CONCLUSIONS Pharmacological approaches to seizure management in end-of-life care are variable, often exceeding APPM dose recommendations. Despite this, safe and effective seizure control was possible in all settings.

Abstract
Delirium is a common problem in terminally ill patients that is associated with significant distress and, hence, considered a palliative care emergency. The three subtypes of delirium are hyperactive, hypoactive, and mixed, depending on the level of psychomotor activity and arousal disturbance. When agitated delirium becomes refractory in the setting of imminent dying, the agitation may be so severe that palliative sedation (PS) is required. Palliative sedation involves the administration of sedative medications with the purpose of reducing level of consciousness for patients with refractory suffering in the setting of a terminal illness. Propofol is a sedative that has a short duration of action and a very rapid onset. These characteristics make it relatively easy to titrate. Reported doses range from 50 to 70 mg per hour. The authors present a case of antipsychotic-resistant agitated delirium treated with a propofol intravenous infusion.

Abstract
Continuous deep sedation at the end of life is a specific form of palliative sedation requiring a care plan that essentially places and maintains the patient in an unresponsive state because their symptoms are refractory to any other interventions. Because this application is uncommon, many providers may lack practical experience in this specialized area and resources they can access are outdated, nonspecific, and/or not comprehensive. The purpose of this review is to provide an evidence- and experience-based reference that specifically addresses those medications and regimens and their practical applications for this very narrow, but vital, aspect of hospice care. Patient goals in a hospital and hospice environments are different, so the manner in which widely used sedatives are dosed and applied can differ greatly as well. Parameters applied in end-of-life care that are based on experience and a thorough understanding of the pharmacology of those medications will differ from those applied in an intensive care unit or other medical environments. By recognizing these different goals and applying well-founded regimens geared specifically for end-of-life sedation, we can address our patients' symptoms in a more timely and efficacious manner.

Abstract
Agitation is a very distressing problem that must be controlled as quickly as possible, but using a safe method. The authors conducted a comparison of two protocols: a combination of haloperidol and midazolam and haloperidol alone. The combination drug protocol controlled 101 out of 121 (84%) episodes of agitation with only the first dose, whereas the haloperidol alone protocol controlled 47 out of 74 (64%) episodes. This difference is statistically significant (P =.002), with a post hoc analyzed power of 0.88. The median time from the first dose to the control of agitation was 15 minutes (range: 5-210) with the combination and 60 minutes (range: 10-430) with the other protocol, P <.001. There were no complications other than some transient somnolence, mainly with the combination protocol. The authors conclude that the combination of haloperidol and midazolam is effective and safe for the control of agitation in palliative care and it is more effective than haloperidol alone. Therefore, the combination should be adopted as the preferred protocol. It would be helpful if the usefulness of this protocol is confirmed by others.

Ethical dilemmas faced by hospice nurses when administering palliative sedation to patients with terminal cancer. Palliat Support Care 2016; 15:148-157.

Abstract
OBJECTIVE Palliative sedation is a method of symptom management frequently used in hospices to treat uncontrolled symptoms at the end of life. There is a substantial body of literature on this subject; however, there has been little research into the experiences of hospice nurses when administering palliative sedation in an attempt to manage the terminal restlessness experienced by cancer patients. METHOD Semistructured interviews were conducted with a purposive sample of seven hospice nurses who had cared for at least one patient who had undergone palliative sedation within the past year in a hospice in the south of England in the United Kingdom. A phenomenological approach and Colaizzi's stages of analysis were employed to develop themes from the data. RESULTS Facilitating a "peaceful death" was the primary goal of the nurses, where through the administration of palliative sedation they sought to enable and support patients to be "comfortable," "relaxed," and "calm" at the terminal stage of their illness. Ethical dilemmas related to decision making were a factor in achieving this. These were: medication decisions, "juggling the drugs," "causing the death," sedating young people, the family "requesting" sedation, and believing that hospice is a place where death is hastened. SIGNIFICANCE OF RESULTS Hospice nurses in the U.K. frequently encounter ethical and emotional dilemmas when administering palliative sedation. Making such decisions about using palliative sedation causes general discomfort for them. Undertaking this aspect of care requires confidence and competence on the part of nurses, and working within a supportive hospice team is of fundamental importance in supporting this practice.

Abstract
Phenobarbital is used in hospice and palliative care to treat refractory symptoms. In end-of-life care, Food and Drug Administration approved routes of administration may be unreasonable based on patients’ status. In these cases, phenobarbital may be administered subcutaneously for symptom management. However, according to the American Hospital Formulary Service, subcutaneous administration of commercially available injectable phenobarbital is cautioned due to possible skin reactions. This study evaluates the tolerability of phenobarbital administered subcutaneously. Of 69 patients and 774 distinct subcutaneous phenobarbital injections, 2 site reactions were recorded (2.9% of patients; 0.3% of injections). Both were mild, grade 1 reactions. Each patient continued to receive subcutaneous phenobarbital via newly placed ports with no additional reactions. Based on these findings, phenobarbital appears to be well tolerated when administered subcutaneously.

Abstract
CONTEXT In end-of-life care, delirium is often not recognized and poses unique management challenges, especially in the case of refractory delirium in the terminal phase. OBJECTIVES To review delirium in the terminal phase context, specifically in relation to recognition issues; the decision-making processes and management strategies regarding its reversibility; the potential refractoriness of delirium to symptomatic treatment; and the role of sedation in refractory delirium. METHODS We combined multidisciplinary input from delirium researchers and knowledge users at an international delirium study planning meeting and relevant electronic database literature searches (Ovid Medline, Embase, PsycINFO, and CINAHL) to inform this narrative review. RESULTS The overall management strategy for delirium at the end of life is directed by the patient's prognosis in association with the patient's goals of care. As symptoms of delirium are often refractory in the terminal phase, especially in the case of agitated delirium, the judicious use of palliative sedation is frequently required. However, there remains a lack of high-level evidence for the management of delirium in the terminal phase, including the role of antipsychotics and optimal sedation strategies. For the family and health-care staff, clear communication, education, and emotional support are vital components to assist with decision making and direct the treatment care plan. CONCLUSION Further research on the effectiveness of delirium management strategies in the terminal phase for patients and their families is required. Further validation of assessment tools for diagnostic screening and severity measurement is needed in this patient population.

Abstract
BACKGROUND Palliative sedation (ps), the continuous use of sedating doses of medication to intentionally reduce consciousness and relieve refractory symptoms at end of life, is ethically acceptable if administered according to standards of best practice. Procedural guidelines outlining the appropriate use of ps and the need for rigorous documentation have been developed. As a quality improvement strategy, we audited the practice and documentation of ps on our palliative care unit (pcu). METHODS A pharmacy database search of admissions in 2008 identified, for a subsequent chart review, patients who had received either a continuous infusion of midazolam (≥10 mg/24 h), regular parenteral dosing of methotrimeprazine (≥75 mg daily), or regular phenobarbital. Documentation of the decision-making process, consent, and medication use was collected using a data extraction form based on current international ps standards. RESULTS Interpretation and comparison of data were difficult because of an apparent lack of a consistent operational definition of ps. Patient records had no specific documentation in relation to ps initiation, to clearly identified refractory symptoms, and to informed consent in 60 (64.5%), 43 (46.2%), and 38 (40.9%) charts respectively. Variation in the medications used was marked: 54 patients (58%) were started on a single agent and 39 (42%), on multiple agents. The 40 patients (43%) started on midazolam alone received a mean daily dose of 21.4 mg (standard deviation: 24.6 mg). CONCLUSIONS The lack of documentation and standardized practice of ps on our pcu has resulted in a quality improvement program to address those gaps. They also highlight the importance of conducting research and developing clinical guidelines in this area.

Phenobarbital but Not Diazepam Reduces AMPA/kainate Receptor Mediated Currents and Exerts Opposite Actions on Initial Seizures in the Neonatal Rat Hippocampus. Front Cell Neurosci 2011; 5:16.

Abstract
Diazepam (DZP) and phenobarbital (PB) are extensively used as first and second line drugs to treat acute seizures in neonates and their actions are thought to be mediated by increasing the actions of GABAergic signals. Yet, their efficacy is variable with occasional failure or even aggravation of recurrent seizures questioning whether other mechanisms are not involved in their actions. We have now compared the effects of DZP and PB on ictal-like events (ILEs) in an in vitro model of mirror focus (MF). Using the three-compartment chamber with the two immature hippocampi and their commissural fibers placed in three different compartments, kainate was applied to one hippocampus and PB or DZP to the contralateral one, either after one ILE, or after many recurrent ILEs that produce an epileptogenic MF. We report that in contrast to PB, DZP aggravated propagating ILEs from the start, and did not prevent the formation of MF. PB reduced and DZP increased the network driven giant depolarizing potentials suggesting that PB may exert additional actions that are not mediated by GABA signaling. In keeping with this, PB but not DZP reduced field potentials recorded in the presence of GABA and NMDA receptor antagonists. These effects are mediated by a direct action on AMPA/kainate receptors since PB: (i) reduced AMPA/kainate receptor mediated currents induced by focal applications of glutamate; (ii) reduced the amplitude and the frequency of AMPA but not NMDA receptor mediated miniature excitatory postsynaptic currents (EPSCs); (iii) augmented the number of AMPA receptor mediated EPSCs failures evoked by minimal stimulation. These effects persisted in MF. Therefore, PB exerts its anticonvulsive actions partly by reducing AMPA/kainate receptors mediated EPSCs in addition to the pro-GABA effects. We suggest that PB may have advantage over DZP in the treatment of initial neonatal seizures since the additional reduction of glutamate receptors mediated signals may reduce the severity of neonatal seizures.

Abstract
INTRODUCTION We undertook a systematic review of published evidence of the effectiveness of propofol for terminal sedation. INCLUSIONS: Prospective or retrospective trials (controlled or uncontrolled) or case series of propofol for sedation in advanced incurable disease in either generalist setting or specialist palliative care units. EXCLUSIONS Use in anesthetic or intensivist settings (e.g., intensive care units); pediatric use. Identification of relevant studies: Using the search terms: [Hospice Care/OR Terminal Care/OR Palliative Care/OR palliative.mp] AND [Propofol/]. Studies were identified using a detailed search strategy from a number of electronic databases: Embase (1988-2005); MEDLINE (1966-2005) Cinahl (1982-2005), Cancerlit (1962-2005) The Cochrane Database of Systematic Reviews 2005 Issue 4. Hand searches of a number of palliative care journals were also undertaken (Palliative Medicine, Journal of Pain and Symptom Management, Progress in Palliative Care, Journal of Palliative Care, Journal of Palliative Medicine). No restriction was placed on the language of the original article. RESULTS Four articles--all case series or case reports--reporting generally favorable reports of the use of propofol as sedation for intractable symptoms in the last days of life especially when one or more other drugs have failed. Since these four articles are essentially hypothesis-generating, the article also discusses the possibility of the design of a clinical trial to compare propofol with other drugs used in this situation.

Abstract
PURPOSE OF REVIEW Palliative sedation, the intentional lowering of consciousness for refractory and unbearable distress, has been much discussed during the last decade. In recent years, much research has been published about this subject that will be discussed in this review. The review concentrates on: a brief overview of the main developments during the last decade, an exploration of current debate regarding ethical dilemmas, the development of clinical guidelines, and the application of palliative sedation. RECENT FINDINGS Main findings are that palliative sedation is mostly described in retrospective studies and that the terminology palliative sedation in now common in the majority of the studies. In addition, life-shortening effects for palliative sedation are scarcely reported, although not absent. A number of guidelines have been developed and published, although systematic implementation needs more attention. Consequently, palliative sedation has become more clearly positioned as a medical treatment, to be distinguished from active life shortening. SUMMARY Caregivers should apply palliative sedation proportionally, guided by the symptoms of the patient without striving for deep coma and without motives for life shortening. Clinical and multidisciplinary assessment of refractory symptoms is recommended as is patient monitoring during sedation. Future research should concentrate on proportional sedation rather than continuous deep sedation exclusively, preferably in a prospective design.

Abstract
BACKGROUND A considerable number of patients admitted to the intensive care unit (ICU) die following withdrawal of mechanical ventilation. After discontinuation of ventilation without proper preparation, excessive respiratory secretion is common, resulting in a 'death rattle'. Post-extubation stridor can give rise to the relatives' perception that the patient is choking and suffering. Existing protocols lack adequate anticipatory preparation to respond to all distressing symptoms. METHODS We analyzed existing treatment strategies in distressing symptoms after discontinuation of mechanical ventilation. CONCLUSION The actual period of discontinuation of mechanical ventilation can be very short, but thoughtful anticipation of distressing symptoms takes time. There is an ethical responsibility to anticipate and treat (iatrogenic) symptoms such as pain, dyspnea-associated respiratory distress, anxiety, delirium, post-extubation stridor, and excessive broncho-pulmonary secretions. This makes withdrawal of mechanical ventilation in ICU patients a thoughtful process, taking palliative actions instead of fast terminal actions. We developed a flowchart covering all possible distressing symptoms that can occur after withdrawal of mechanical ventilation and extubation. We recommend a two-phase process. Six hours before extubation, enteral feeding should be stopped and parenteral fluids reduced, overhydrated patients should be dehydrated with furosemide, administration of sedatives (for distress) and opioids (for pain and/or dyspnea) should be continued or started and methylprednisolone should be given in anticipation of stridor after extubation. Thirty minutes before extubation, Butylscopolamine should be given and methylprednisolone repeated. After this the patient should be extubated to secure a dying process as natural as possible with the lowest burden due to distress.

Abstract
PURPOSE Our goal was to report on the incidence of sedation failures in our outpatient oral surgery clinic. Sedation failure is the inability to complete a procedure under intravenous sedation. There is very little in the oral surgery literature on this subject. MATERIALS AND METHODS Proper Institutional Review Board approval was obtained from the appropriate governing body for this project. The medical records of 539 intravenous sedation patients treated at the Oral and Maxillofacial Surgery Clinic at our institution were retrospectively evaluated to determine the incidence of failed sedation. Patients sedated with midazolam and fentanyl were placed in group A. There were 323 patients in group A. We placed patients sedated with midazolam, fentanyl and methohexital into group B. There were 216 patients in group B. The gender, medical history, type of procedure being performed, amount of drug given, and the patient's vital signs throughout the procedure were recorded. RESULTS There were 9 failed sedations with a rate of 1.6% (9/539); 3 in group B (1%) and 6 in group A (2%). Five of our failures were undergoing multiple tooth extractions. Two of the failures were undergoing surgical removal of impacted third molars. Two patients underwent mandibular fracture reduction. Failure was attributed to increased agitation and combativeness, uncontrolled hypertension, tachycardia and desaturation. CONCLUSION The mandible fracture population and multiple teeth extraction patients had higher rates of failure than other groups. This may be the result of procedure length, type of procedure, or a preoperative anxiety and attitude toward treatment expressed by the patient making sedation unpredictable. Level of training and experience of the practitioner may contribute to sedation failure. These results allow us to develop a prospective study protocol of outpatient sedation and to quantify more detailed information about preoperative anxiety, medical status, and social history than we had available during our chart review. More specific conclusions may help us determine if certain patient populations are at a higher risk for failed sedations.

Abstract
PURPOSE Palliative sedation therapy (PST) is a controversial issue. There is a need for internationally accepted definitions and standards. METHODS A systematic review of the literature was performed by an international panel of 29 palliative care experts. Draft papers were written on various topics concerning PST. This paper is a summary of the individual papers, written after two meetings and extensive e-mail discussions. RESULTS PST is defined as the use of specific sedative medications to relieve intolerable suffering from refractory symptoms by a reduction in patient consciousness, using appropriate drugs carefully titrated to the cessation of symptoms. The initial dose of sedatives should usually be small enough to maintain the patients' ability to communicate periodically. The team looking after the patient should have enough expertise and experience to judge the symptom as refractory. Advice from palliative care specialists is strongly recommended before initiating PST. In the case of continuous and deep PST, the disease should be irreversible and advanced, with death expected within hours to days. Midazolam should be considered first-line choice. The decision whether or not to withhold or withdraw hydration should be discussed separately. Hydration should be offered only if it is considered likely that the benefit will outweigh the harm. PST is distinct from euthanasia because (1) it has the intent to provide symptom relief, (2) it is a proportionate intervention, and (3) the death of the patient is not a criterion for success. PST and its outcome should be carefully monitored and documented. CONCLUSION When other treatments fail to relieve suffering in the imminently dying patient, PST is a valid palliative care option.

Abstract
A 62-year-old man visited our clinic for dental implantation under intravenous sedation. He demonstrated increased psychomotor activity and incomprehensible verbal contact during intravenous sedation. Although delirium caused by midazolam or propofol in different patients has been reported, the present case represents a delirium that developed from both drugs in the same patient, possibly because of the patient's smaller tolerance to midazolam and propofol.

Abstract
Benzodiazepines, neuroleptics, and barbiturates are commonly used for sedation to achieve symptom control in end-of-life care. Propofol has several advantages over traditional sedating agents that would indicate its use in treatment-refractory situations. We report on the use of propofol in 35 patients. In 22 patients, propofol was used for palliative sedation when treatment with benzodiazepines had failed. The mean dose range during treatment was between 0.90 and 2.13 mg/kg/h. The effect was assessed as good or very good in 91% of the patients. Thirteen patients were treated with propofol due to intractable nausea and vomiting. The mean dose range during the infusion period was 0.67-1.01 mg/kg/h. The effect was judged as good or very good in 69% of the patients. Based on our experience, we propose clinical guidelines on the safe use of propofol in specialized palliative inpatient units.

Abstract
Although palliative sedation therapy is often required in terminally ill cancer patients, its efficacy and safety are not sufficiently understood. The primary aims of this multicenter observational study were to 1) explore the efficacy and safety of palliative sedation therapy, and 2) identify the factors contributing to inadequate symptom relief and complications, using a prospective study design, clearly defined measurement methods, and a consecutive sample from 21 specialized palliative care units in Japan. A sample of 102 consecutive adult cancer patients who received continuous deep sedation were enrolled. Physicians prospectively evaluated the intensity of patient symptoms, communication capacity, respiratory rate, and complications related to sedation. Symptoms were measured on the Agitation Distress Scale, the Memorial Delirium Assessment Scale, and the ad hoc symptom severity scale (0 = no symptoms, 1 = mild and tolerable symptoms, 2 = intolerable symptoms for less than 15 minutes in the previous one hour, and 3 = intolerable symptoms continuing for more than 15 minutes in the previous one hour). Inadequate symptom relief was defined as presence of hyperactive delirium (item 9 of the Memorial Delirium Assessment Scale >or=2) or grade 2 or 3 symptom intensity 4 hours after sedation. The degree of communication capacity was measured on the Communication Capacity Scale. Palliative sedation therapy succeeded in symptom alleviation in 83% of the cases. Median time elapsed before patients initially had one continuous hour of deep sedation was 60 minutes, but 49% of the patients awakened once after falling into a deeply sedated state. The percentage of patients who were capable of explicit communication decreased from 40% before sedation to 7.1% 4 hours after sedation, and the mean Communication Capacity Score significantly decreased to the level of 15 points (P < 0.001). The respiratory rates did not significantly decrease after sedation (18 +/- 9.0 to 16 +/- 9.4/min, P = 0.62), but respiratory and/or circulatory suppression (respiratory rate <or= 8/min, systolic blood pressure <or= 60mHg, or 50% or more reduction) occurred in 20%, with fatal outcomes in 3.9%. There were no statistically significant differences in patient age, sex, performance status, target symptoms, or classes and initial dose of sedative medications between the patients with adequate and inadequate symptom relief. Respiratory and/or circulatory suppression was significantly more likely to occur in patients receiving sedation for delirium and those with higher levels on the Agitation Distress Scale. Higher dose of midazolam was significantly correlated with younger age, absence of icterus, pre-exposure to midazolam, and length of sedation. Palliative sedation therapy is effective and safe in the majority of terminally ill cancer patients with refractory symptoms. However, a small number of patients experience fatal complications related to sedation. Comparison studies of different sedation regimens are needed to determine the most effective and safe sedation protocol.

Abstract
BACKGROUND After alarming reports concerning deaths after sedation with propofol, infusion of this drug was contraindicated by the US Food and Drug Administration in children <18 yr receiving intensive care. We describe our experiences with propofol 6%, a new formula, during postoperative sedation in non-ventilated children following craniofacial surgery. METHODS In a prospective cohort study, children admitted to the paediatric surgical intensive care unit following major craniofacial surgery were randomly allocated to sedation with propofol 6% or midazolam, if judged necessary on the basis of a COMFORT behaviour score. Exclusion criteria were respiratory infection, allergy for proteins, propofol or midazolam, hypertriglyceridaemia, familial hypercholesterolaemia or epilepsy. We assessed the safety of propofol 6% with triglycerides (TG) and creatine phosphokinase (CPK) levels, blood gases and physiological parameters. Efficacy was assessed using the COMFORT behaviour scale, Visual Analogue Scale and Bispectral Index monitor. RESULTS Twenty-two children were treated with propofol 6%, 23 were treated with midazolam and 10 other children did not need sedation. The median age was 10 (IQR 3-17) months in all groups. Median duration of infusion was 11 (range 6-18) h for propofol 6% and 14 (range 5-17) h for midazolam. TG levels remained normal and no metabolic acidosis or adverse events were observed during propofol or midazolam infusion. Four patients had increased CPK levels. CONCLUSION We did not encounter any problems using propofol 6% as a sedative in children with a median age of 10 (IQR 3-17) months, with dosages <4 mg kg(-1) h(-1) during a median period of 11 (range 6-18) h.

Abstract
A significant number of patients with terminal cancer experience terminal restlessness or an agitated delirium in the final days of life. Multifactorial etiologies may contribute to agitation and restlessness for any one patient; alcohol withdrawal may be underrated as a contributing factor. The symptoms and signs of alcohol withdrawal--autonomic dysfunction, tremor, anxiety, sleep disturbances, insomnia, and abnormal vital signs--may continue for 6 to 12 months after the cessation of alcohol. We report four patients with terminal restlessness in whom we believe alcohol withdrawal to be a significant causal factor and a fifth patient who subsequently benefited from our team's increased awareness of this clinical problem. Formal assessment of alcohol withdrawal may be of more value in the palliative setting than using the currently accepted assessment instruments. Many of the medications utilized for the treatment of agitated delirium and terminal restlessness in the palliative care setting are effective therapies for alcohol withdrawal.

Abstract
Delirium in advanced cancer is often poorly identified and inappropriately managed. It is one of the most common causes for admission to clinical institutions and is the most frequently cited psychiatric disorder in terminal cancer. Diagnosis of delirium is defined as a disturbance of consciousness and attention with a change in cognition and/or perception. In addition, it develops suddenly and follows a fluctuating course and it is related to other causes, such as cancer, metabolic disorders or the effects of drugs. Delirium occurs in 26% to 44% of cancer patients admitted to hospital or hospice. Of all advanced cancer patients, over 80% eventually experience delirium in their final days. In advanced cancer, delirium is a multifactorial syndrome where opioids factor in almost 60% of episodes. Delirium in such patients, excluding terminal delirium, may be reversible in 50% of cases. Providing adequate end-of-life care for a patient with delirium is the main challenge. The family needs advice and it is important to create a relaxing environment for the patient. The primary therapeutic approach is to identify the reversible causes of delirium. Some therapeutic strategies have been shown to be effective: reduction or withdrawal of the psychoactive medication, opioid rotation, and hydration. Haloperidol is the most frequently used drug, and new neuroleptics such as risperidone or olanzapine are being tested with good results. Methylphenidate has been used for hypoactive delirium.
