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

4. Consider benzodiazepines to decrease
neuromuscular irritability & adjunct anti-seizure

• PRN dosing of either fentanyl,
sufentanil, or methadone
• Don’t try to calculate an appropriate

use…. Start low and titrate up *
• After a few hours, consider starting a
regular administration (infusion,
perhaps oral methadone)
CHALLENGES IN MANAGING PAIN /
DISTRESS IN SETTINGS OF
NEUROTOXICITY
Quite possible that a substantial proportion of the current
offending opioid dose is being targeted at treating opioidinduced hyperalgesia or restlessness
The opioid has been increased to treat its own side effects
PEARL: + tolerance to the offending opioid, not “crossedover” to alternatives (incomplete cross-tolerance)
Impossible to calculate dose equivalences of alternative
opioids. Conversion charts should not be used here!
Discontinue the Offending Opioid
PEARLS
•
Simply decreasing the dose only postpones the need
to switch opioids
•
Adding a benzodiazepine without addressing the
opioid ignores potential reversibility
•
Do a stepwise conversion (days) in mild
neurotoxicity

Use abrupt discontinuation if life-threatening
neurotoxicity (seizures imminent)!!

Medically assisted hydration for palliative care patients

Level of evidence = D
There is insufficient evidence on the use of medically assisted hydration in palliative care
patients.
• A Cochrane review included 5 studies with a total of 453 subjects. Two were RCTs and
three prospective controlled trials. All of the studies included only participants with
advanced cancer.
• One study found that sedation and myoclonus (involuntary contractions of muscles) were
improved more in the intervention group (28 - hydration, 23 - placebo). Another study
found that dehydration was significantly higher in the non-hydration group, but that some
fluid retention symptoms (pleural effusion, peripheral edema and ascites) were
significantly higher in the hydration group (59 - hydration group, 167 - non -hydration
group). The other three studies did not show significant differences in outcomes between
the two groups.
• Comment: The quality of evidence is downgraded by imprecise results (limited study
size for each comparison) and study quality (several issues).

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.

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.

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

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

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.

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.

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.

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.

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.

Drug Therapy for delirium in terminally ill adultsCochrane Review 2004
One trial met the criteria for inclusion. In the 2012 update search
we retrieved 3066 citations but identified no new trials. The
included trial evaluated 30 hospitalized AIDS patients receiving
one of three agents: chlorpromazine, haloperidol and lorazepam.
The trial under-reported key methodological features.
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.

The Golden One!!
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.

• Rapid and safe titration can be used until symptoms are
relieved.
• Continue to assess benefits and side effects
• Once symptom controlled the total dose in last 24hrs
should be administered routine once every half life.
