Assessment Treatment Discussion Myoclonus In these cases-symptomatic treatment only is justified if the myoclonus is disabling. TREATMENT STEPS 1. Recognize the syndrome 2. Discontinue the offending opioid Note: naloxone does not reverse neuroexcitatory effects, and may in fact exacerbate them 3. Consider Hydration to help clear opioid and metabolites** 4.

Persistent and intractable hiccups (typically defined as lasting for more than 48 hours and one month respectively) can be of serious detriment to a patient's quality of life, although they are relatively uncommon. A wide range of pharmacological and non-pharmacological interventions have been used for the treatment of persistent and intractable hiccups. However, there is little evidence as to which interventions are effective or harmful. OBJECTIVES: The objective of this review was to evaluate the effectiveness of pharmacological and non-pharmacological interventions used in the treatment of persistent and intractable hiccups of any aetiology in adults. SEARCH METHODS: Studies were identified from the following databases: CENTRAL, CDSR, DARE, MEDLINE, EMBASE, CINAHL, PsychINFO and SIGLE (last search March 2012). The search strategy for all the databases searched was based on the MEDLINE search strategy presented in Appendix 1. No additional handsearching of journals was undertaken. Investigators who are known to be carrying out research in this area were contacted for unpublished data or knowledge of the grey literature. SELECTION CRITERIA: Studies eligible for inclusion in this review were randomized controlled trials (RCTs) or controlled clinical trials (CCTs). INCLUSION CRITERIA: adults (over 18 years old) diagnosed with persistent or intractable hiccups (hiccups lasting more than 48 hours), treated with any pharmacological or nonpharmacological intervention. EXCLUSION CRITERIA: less than ten participants; no assessment of change in hiccup frequency or intensity in outcome measures. DATA COLLECTION AND ANALYSIS: Two independent review authors assessed each abstract and title for relevance. Disagreement on eligibility was resolved by discussion. Where no abstract was available the full paper was obtained and assessed. We obtained full copies of the studies which met the inclusion criteria for further assessment. Two review authors independently collected data from each appropriate study and entered them into the software Review Manager 5. Two independent review authors assessed the risk of bias using the RevMan 5 'Risk of bias' table following guidance from the Cochrane Handbook of Systematic Reviews of Interventions (Higgins 2009). MAIN RESULTS: A total of four studies (305 participants) met the inclusion criteria. All of these studies sought to determine the effectiveness of different acupuncture techniques in the treatment of persistent and intractable hiccups. All four studies had a high risk of bias, did not compare the intervention with placebo, and failed to report side effects or adverse events for either the treatment or control groups. Due to methodological differences we were unable to perform a meta-analysis of the results. No studies investigating pharmacological interventions for persistent and intractable hiccups met the inclusion criteria. AUTHORS' CONCLUSIONS: There is insufficient evidence to guide the treatment of persistent or intractable hiccups with either pharmacological or non-pharmacological interventions.The paucity of high quality studies indicate a need for randomized placebo-controlled trials of both pharmacological and nonpharmacological treatments. As the symptom is relatively rare, trials would need to be multi-centered and possibly multi-national.

Abstract Review of Literature Classification Pathophysiology Assessment Treatment Discussion AHEAD OF PRINT BACKGROUND: Hiccups are familiar to everyone, but remain poorly understood. Acute hiccups can often be terminated by physical maneuvers. In contrast, persistent and intractable hiccups that continue for days or months are rare, but can be distressing and difficult to treat. AIM: To review the management of hiccups, including a systematic review of reported efficacy and safety of pharmacological treatments. METHODS: Available articles were identified using three electronic databases in addition to hand searching of published articles. Inclusion criteria were any reports of pharmaceutical therapy of 'hiccup(s)', 'hiccough(s)' or 'singultus' in English or German. RESULTS: Treatment of 341 patients with persistent or intractable hiccups was reported in 15 published studies. Management was most effective when directed at the underlying condition. An empirical trial of anti-reflux therapy may be appropriate. If the underlying cause is not known or not treatable, then a range of pharmacological agents may provide benefit; however, systematic review revealed no adequately powered, well-designed trials of treatment. The use of baclofen and metoclopramide are supported by small randomized, placebo-controlled trials. Observational data suggest that gabapentin and chlorpromazine are also effective. Baclofen and gabapentin are less likely than standard neuroleptic agents to cause side effects during long-term therapy. CONCLUSIONS: This systematic review revealed no high quality data on which to base treatment recommendations. Based on limited efficacy and safety data, baclofen and gabapentin may be considered as first line therapy for persistent and intractable hiccups, with metoclopramide and chlorpromazine in reserve. Systemic review: the pathogenesis and pharmacological treatment of hiccups: Aliment Pharmacol Ther 2015 Review of Literature Classification Hiccups are usually classified as: • Benign or Physiological: 24-48 hrs • Persistent: 48 Hrs- 1 month) • Intractable (>1 month). Pathophysiology Assessment Treatment Discussion A Physiological hiccup is usually of short duration (less than 48 hours). It may be caused by, e.g., overeating, ETOH, carbonated drinks or changes in temperature. Classification Review of Literature Classification Pathophysiology Assessment • Hiccup is “likely” generated by a reflex arc involving the peripheral branch of the phrenic nerve, the vagus nerve and the sympathetic nervous system. Treatment Discussion Hiccups • Any factor stimulating these nerves and thus the reflex arc may cause hiccup. • Hiccups are caused by a sudden, involuntary, myoclonic contraction of the diaphragm and inspiratory intercostal muscles terminated by abrupt closure of the glottis stopping the inflow of air and producing the characteristic sound. • Hiccups usually occur with a frequency of 4 to 60 a minute. The medical term for hiccup is singultus, from the Latin singult, meaning the act of catching one's breath while sobbing.

Abstract OBJECTIVE: To determine whether gabapentin is effective in the treatment of persistent or intractable hiccups. DATA SOURCES: A search of MEDLINE (1966-March 2013) using the MeSH search terms gabapentin, hiccups, and hiccups/drug therapy was performed. Additional databases searched included Web of Science (1945-March 2013) and International Pharmaceutical Abstracts (1970-March 2013) using the text words gabapentin and hiccups. Bibliographies of relevant articles were reviewed for additional citations. STUDY SELECTION AND DATA EXTRACTION: All data sources were considered for inclusion. Preference was given for articles written in English, although one abstract in German was used. DATA SYNTHESIS: Because of the low incidence of persistent or intractable hiccups, few if any controlled clinical trials are conducted on the efficacy of drug treatment. Therefore, most of the data involve case reports or case series. We evaluated 17 case reports and 2 case series involving gabapentin therapy for persistent or intractable hiccups. Therapeutic outcomes with gabapentin were positive in all cases, with temporal evidence suggesting an effect, but outcomes often were obscured by combination therapy and comorbidities in some cases. Case reports suggest that gabapentin might be useful as a second-line agent in patients undergoing stroke rehabilitation or in the palliative care setting where chlorpromazine adverse effects are undesirable. Gabapentin was very well tolerated, with only a few minor adverse effects. CONCLUSIONS: Gabapentin has a similar body of evidence as other pharmacotherapeutic agents used to treat hiccups. Gabapentin is well tolerated and should be considered as a second-line agent in selected patients Ann Pharmacother. 2013 Gabapentin therapy of hiccups. Abstract AIM: To evaluate safety and efficacy of gabapentin in the treatment of severe chronic hiccups in patients with advanced cancer. METHODS: Charts of all patients observed in the palliative care unit of a 4-bed hospital and at home by our Home Care Service were reviewed retrospectively.The presence of hiccups was routinely assessed. Patients with severe chronic hiccups were treated with gabapentin (300 mg t.i.d.). Doses of gabapentin were titrated based on the response to treatment.Gabapentin-related adverse effects were recorded. RESULTS: Thirty-seven (3.9%) of 944 in-hospital patients and 6 (4.5%) of 134 patients observed at home presented severe chronic hiccups.We registered an improvement of hiccups, defined as complete resolution of hiccups, in 31 (83.8%) of 37 in-hospital patients and 4 (66.7%) of 6 patients observed at home.Four (10.8%) of the 37 in-hospital patients and 2 (33.3%) of the 6 patients observed at home experienced a reduction of hiccups.In 2 patients (5.4%), we registered a worsening of hiccups.Responses were observed in 32 patients (74.4%) with gabapentin at a dosage of 900 mg/d and in 9 patients (20.93%) at 1200 mg/d.In 2 patients (4.65%), grade 2 sleepiness was observed and in 10 patients (23.25%), grade 1 sleepiness was observed based on the Epworth Sleepiness Scale. CONCLUSION: The results of the study allow suggesting gabapentin at least as a promising drug in the treatment of severe chronic hiccups in advanced cancer patients.

REVIEWS Abstract BACKGROUND: Noisy breathing (death rattle) occurs in 23 to 92% of people who are dying. The cause of death rattle remains unproven but is presumed to be due to an accumulation of secretions in the airways. It is therefore managed physically (repositioning and clearing the upper airways of fluid with a mechanical sucker) or pharmacologically (with anticholinergic drugs). OBJECTIVES: To describe and assess the evidence for the effectiveness of interventions used to treat death rattle in patients close to death. SEARCH STRATEGY: Randomised controlled trials (RCTs), before and after studies and interrupted time series (ITS) studies in adults and children with death rattle were sought by MEDLINE (1966 to 2007), EMBASE (1980 to 2007), CINAHL (1980 to 2007), the Cochrane Pain, Palliative and Supportive Care Trials Register and the Cochrane Central Register of Controlled Trials. In addition, the reference lists of all relevant trials and reports were checked and investigators who are known to be researching this area were contacted for unpublished data or knowledge of the grey literature. SELECTION CRITERIA: RCTs, controlled before and after studies and ITS reporting the outcome of pharmacological and non-pharmacological interventions for treating death rattle. DATA COLLECTION AND ANALYSIS: Data was extracted by two independent review authors and trials were quality scored. There was insufficient data to carry out an analysis. MAIN RESULTS: Thirty studies were identified, of which only one study met the inclusion criteria. This small study was a randomised placebo-controlled trial of the use of hyoscine hydrobromide in patients with death rattle. Hyoscine hydrobromide tended to reduce death rattle compared to placebo but this was not significant. A larger randomised study, comparing atropine, hyoscine butylbromide and scopolamine, is in progress. AUTHORS' CONCLUSIONS: There is currently no evidence to show that any intervention, be it pharmacological or non-pharmacological, is superior to placebo in the treatment of death rattle. We acknowledge that in the face of heightened emotions when death is imminent, it is difficult for staff not to intervene. It is therefore likely that the current therapeutic options will continue to be used. However, patients need to be closely monitored for lack of therapeutic benefit and adverse effects while relatives need time, explanation and reassurance to relieve their fears and concerns. There is a need for more well-designed multi-centre studies with objective outcome measures and the ability to recruit sufficient numbers. Cochrane Database Syst Rev. 2008 Interventions for noisy breathing in patients near to death. Death rattle is a frequent symptom (25%-50%) in the terminal stage of life, but there is neither standardized treatment nor prospective investigation performed on the effectiveness of anticholinergic drugs. The aim of the present study was to investigate the effectiveness of three different anticholinergic drugs in the treatment of death rattle in the terminal stage of life. Terminal patients who developed death rattle were randomly assigned 0.5mg atropine, 20mg hyoscine butylbromide, or 0.25mg scopolamine. Each treatment was initiated with a subcutaneous bolus, which was followed by continuous administration of the same drug. The intensity of death rattle and side effects were prospectively scored at different time points. Three hundred and thirty-three eligible patients were randomized to atropine, hyoscine butylbromide, or scopolamine after informed consent from the patient or the appointed representative. For the three drugs, death rattle decreased to a nondisturbing intensity or disappeared after one hour in 42%, 42%, and 37% of cases, respectively (P =0.72). Further, effectiveness improved over time without significant differences among the treatment groups (effectiveness at 24 hours was 76%, 60%, and 68%, respectively). In an analysis on the three groups together, treatment was more effective when started at a lower initial rattle intensity; median survival after start of therapy was 23.9 hours. These data suggest that there are no significant differences in effectiveness or survival time among atropine, hyoscine butylbromide, and scopolamine in the treatment of death rattle. Atropine, Hyoscine Butylbromide, or Scopolamine Are Equally Effective for the Treatment of Death Rattle in Terminal Care , Abstract: J of Pain and Symp Mgt 2009 Abstract BACKGROUND: Studies examining the effectiveness of treatment in reducing the noises of death rattle have been conducted; however, the physical impact of death rattle on the patient experiencing the phenomenon has not been investigated. Treatments may be undertaken to appease family and staff but these treatments may be more burdensome than beneficial to the patient. Further, nonbeneficial treatments increase the cost of care. OBJECTIVE: To determine if patients with naturally occurring death rattle experience respiratory distress. DESIGN: A prospective, two-group observation study was conducted. Patients who were near death were stratified into those with and without death rattle. SETTING/SUBJECTS: Seventy-one dying patients were recruited from three palliative care and hospice settings. Patients were excluded if they had an artificial airway or if their clinical condition caused a secondary source of death rattle, identified as pseudo-death rattle. MEASUREMENTS: Daily observations were made for death rattle intensity and respiratory distress along with use of antisecretory medications. RESULTS: About half of the sample had no death rattle (55%).There were no differences in respiratory distress when patients with and without death rattle were compared (t=1.48, p=0.143). Death rattle intensity and respiratory distress were not correlated (r=-0.13, p=0.477). Few patients (17%) were medicated with antisecretory agents. Many (58%) patients receiving an antisecretory agent did not experience a reduction in death rattle. CONCLUSIONS: Respiratory distress was not associated with death rattle among patients who were near death. In many cases, antisecretory agents did not produce quiet breathing. J Palliat Med. 2013 Death rattle is not associated with patient respiratory distress: is pharmacologic treatment indicated? Abstract CONTEXT: Noisy breathing because of respiratory tract secretions (RTS), often referred to as "death rattle," occurs in up to half of all dying patients. Despite a lack of evidence showing benefit compared with placebo, antimuscarinic medications have been used in an attempt to decrease noise associated with RTS and to decrease family distress. OBJECTIVES: The goal of this study was to compare the efficacy of the antimuscarinic medication atropine with that of placebo in reducing noise associated with death rattle. METHODS: Terminally ill adult hospice inpatients who developed noisy breathing as a result of RTS were randomized to double-blind treatment with atropine or placebo. Study drug was given as a single sublingual dose. Noise from breathing was monitored at baseline and at two and four hours. RESULTS: One hundred thirty-seven participants were randomized to atropine or placebo. Reduction in noise score from baseline to two hours after dose occurred in 37.8% and 41.3% of subjects treated with atropine and placebo, respectively (P=0.73). Noise score reduction at four hours occurred in 39.7% and 51.7% of subjects treated with atropine and placebo, respectively (P=0.21). Differences between groups were not significant at either time point. Atropine was well tolerated. Heart rate increased slightly in both groups (+1.1/minute for atropine and +3.1/minute for placebo) but not significantly. CONCLUSION: Sublingual atropine given as a single dose was not more effective than placebo in reducing the noise associated with death rattle.

Abstract PURPOSE: Anticholinergic medications for reducing noisy respirations in adult hospice patients are evaluated. SUMMARY: Anticholinergic medications used to reduce noisy respirations from retained secretions in terminal patients include atropine, glycopyrrolate, scopolamine, and scopolamine derivatives. Pharmaceutical anticholinergic treatment of retained secretions in hospice patients was evaluated in six studies, three of which compared the efficacy of glycopyrrolate to scopolamine in actively dying patients. Subcutaneous glycopyrrolate, scopolamine hydrobromide, and scopolamine butylbromide were similar in their ability to reduce noisy respirations overall and lower and the level of distress exhibited by family members and visitors. Two of the six studies compared the efficacy of medication therapy after institutional formulary changes from scopolamine to glycopyrrolate. The same dosages of subcutaneous glycopyrrolate and scopolamine, which delivered an initial bolus followed by continuous infusion, were reported in each study. Both studies concluded that there was equivalent efficacy between the two products. One study reported a more rapid response in patients treated with glycopyrrolate. In comparison, the last study reported more rapid responses in patients who received scopolamine compared with patients who received glycopyrrolate. Retrospective reports described symptom improvement with parenteral scopolamine in most patients. CONCLUSION: Parenteral and transdermal anticholinergic medications are useful for the reduction of noisy respirations in hospitalized hospice patients. Difficult administration makes oral and sublingual products less desirable for use in this population.

Discussion Pharmacology TREATMENT Review of Literature Classification Pathophysiology Assessment Treatment • The primary difference in these drugs is whether they are tertiary amines which cross the blood-brain barrier (scopolamine, atropine, hyoscyamine) • Quaternary amines, which do not (glycopyrrolate). • Drugs which cross the blood-brain barrier are apt to cause CNS toxicity (sedation, delirium).

Authors' conclusions There remains insufficient evidence to draw conclusions about the role of drug therapy in the treatment of delirium in terminally ill patients. Thus, practitioners should continue to follow current clinical guidelines. Further research is essential. Cochrane Reference Gagnon, P. (2008).

Once a diagnosis of delirium is made: • • • • Assess associated symptoms that need to be addressed Look for any likely underlying cause Assess the patients functional status and prognosis What are the Patient and families goals of care?? The above will help determine whether the delirium is potentially reversible or irreversible. Delirium Potential reversibility- One has to know underlying diagnosis, comorbidities, prognosis, functional status, etc. Irreversible delirium: Time limited diagnostic and adequate therapeutic trial to reverse the delirium is: 1. Inconsistent with goals of care 2. Fails to discover etiologies or fails to reverse 3. The underlying physiological processes are irreversible; end stage organ failure, imminent death (hours to days) As dying is an irreversible process, the associated delirium is also irreversible and should be managed accordingly.
