Stopping Hiccups: A Guide For Stroke Patients And Caregivers

Hiccups are a common complication for stroke patients, and they can be challenging to manage. Strokes can disrupt the breathing centre in the brain, leading to frequent or nonstop bouts of hiccups. While time is typically the best cure for hiccups, persistent hiccups in stroke patients may require medical intervention. This is because the cause of the hiccups must be located and corrected to prevent further complications. Pharmacological interventions such as chlorpromazine, baclofen, and gabapentin are often used to treat persistent hiccups in stroke patients. These interventions must be tailored to the unique circumstances of each patient. In some cases, an inpatient rehabilitation setting and a multidisciplinary team approach may be necessary to optimise feeding management and prevent potentially fatal consequences.

Chlorpromazine or baclofen can be prescribed to treat constant hiccups in stroke patients

Chlorpromazine is a medication that acts by blocking dopamine in the hypothalamus. While it has been effective in treating hiccups, it is associated with serious potential side effects such as hypotension, urinary retention, glaucoma, and delirium. Therefore, it is generally not recommended as the first course of treatment. The typical dosage of chlorpromazine for hiccups is 25 mg four times a day, which can be increased to 50 mg four times a day if necessary.

Baclofen, on the other hand, is a GABA analogue that creates a perceptual blockage in synaptic transmission. It has been shown to be effective in treating hiccups in several small trials and case studies. The typical dosage of baclofen is 10 mg three times a day for five days. While baclofen is generally well-tolerated, it may cause side effects such as ataxia, delirium, dizziness, and sedation. It is important to note that baclofen-related delirium is more common in patients with renal failure, and dose adjustments may be necessary in such cases.

In a randomised, double-blind, placebo-controlled trial, baclofen was found to be more effective than a placebo in treating persistent hiccups in stroke patients. In this study, 30 stroke patients with persistent hiccups were randomly assigned to receive either baclofen or a placebo for five days. The results showed that the number of patients whose hiccups completely stopped was significantly higher in the baclofen group compared to the placebo group. Additionally, the efficacy of baclofen was higher than that of the placebo. No serious adverse events were reported in either group, although mild transient drowsiness and dizziness were observed in two patients in the baclofen group.

In conclusion, chlorpromazine and baclofen are two prescription medications that can be used to treat persistent hiccups in stroke patients. While chlorpromazine has been a traditional treatment option, baclofen has emerged as a promising alternative with fewer side effects. Further research with larger sample sizes is needed to confirm the efficacy and safety of these treatments for stroke patients with persistent hiccups.

Hiccups can be caused by supratentorial infarcts in the insular cortex, temporal lobe, and subcortex

Hiccups are a temporary movement disorder that involves the brain, spinal cord, nerves, and muscles. They are caused by an involuntary spasm of the diaphragm and the sudden closure of the glottis, resulting in a distinctive 'hic' sound. Strokes can disrupt the breathing centre of the brain, leading to hiccups.

Hiccups can be caused by supratentorial infarcts, which are lesions in the brain caused by a blockage or leak in a blood vessel. These infarcts can occur in the insular cortex, temporal lobe, and subcortex. The insular cortex is associated with cardiac autonomic failure in stroke patients, and injuries in this region can result in hiccups. The temporal lobe is also implicated in the development of hiccups when damaged by supratentorial infarcts.

Supratentorial infarcts can cause disruptions in the reflex arch for hiccups, which consists of an afferent pathway (phrenic nerve, vagus nerve, or sympathetic afferents), a hiccup centre (likely in the brainstem), and an efferent pathway (primarily the phrenic nerve). Damage to any of these components can lead to hiccups.

In addition, subcortical regions adjacent to the insular cortex, such as the basal ganglia, inner capsule, and corona radiata, may play a role in inhibiting the hiccup reflex. Disruption of these inhibitory controls can result in altered sympathetic tone and the development of hiccups.

While time is often the best cure for hiccups, some stroke patients may require prescription medications like chlorpromazine or baclofen to alleviate constant hiccups. These medications can help manage the symptoms and provide relief to stroke patients experiencing persistent hiccups.

Persistent hiccups can be a rare symptom of pulmonary embolism in stroke patients

In the context of stroke patients, it is essential to understand the different types of strokes and their impact on hiccups. The two main types of strokes are ischemic and hemorrhagic. An ischemic stroke occurs when a blood vessel in the brain becomes blocked, resulting in reduced blood flow to the brain. On the other hand, a hemorrhagic stroke happens when a blood vessel in the brain leaks or bursts. Both types of strokes can disrupt the breathing centre in the brain, leading to hiccups.

To effectively manage persistent hiccups in stroke patients, it is crucial to identify the underlying cause. In some cases, the hiccups may be a symptom of an underlying condition, such as pulmonary embolism. Therefore, a comprehensive medical evaluation is necessary to rule out any serious underlying conditions. This may include diagnostic tests such as computed tomography (CT) scans or magnetic resonance imaging (MRI) to identify any blockages or abnormalities in the brain or lungs.

Additionally, there are several treatment options available for persistent hiccups in stroke patients. These can include:

• Chlorpromazine: This medication is often prescribed to treat constant hiccups in stroke patients. It helps to suppress the hiccup reflex and reduce the frequency and intensity of hiccups.
• Baclofen: Baclofen is a muscle relaxant that has been found effective in treating persistent hiccups. It acts on the central nervous system and can help alleviate spasms in the diaphragm, reducing the occurrence of hiccups.
• Other medications: In some cases, other medications such as gabapentin, haloperidol, or metoclopramide may be prescribed to manage persistent hiccups. These drugs work by calming the nerves or reducing muscle spasms.
• Physiological methods: In addition to medication, there are simple physiological techniques that can help alleviate hiccups. These include breathing exercises, such as deep breathing or breathing into a paper bag, as well as drinking water slowly or sucking on ice chips.

It is important to note that the treatment plan may vary depending on the patient's medical history, the severity of hiccups, and the presence of any underlying conditions. Therefore, it is crucial to consult with a healthcare professional to determine the most appropriate treatment approach for each individual case.

Stroke patients may be prescribed 10 mg of baclofen three times a day for five days to treat hiccups

Stroke patients may experience frequent or nonstop bouts of hiccups after their stroke. This is due to the stroke disrupting the breathing centre in the brain. In some cases, stroke patients are prescribed baclofen to treat their persistent hiccups.

A 2014 randomised, double-blind, placebo-controlled trial found that 10 mg of baclofen, taken three times a day for five days, was effective in treating persistent hiccups in stroke patients. In the trial, 30 stroke patients with persistent hiccups were randomly assigned to receive either baclofen or a placebo. The number of patients whose hiccups completely stopped was higher in the baclofen group than in the placebo group (14 vs 2). Furthermore, the efficacy of the treatment was higher in the baclofen group than in the placebo group. No serious adverse events were documented in either group, although two patients in the baclofen group reported mild side effects of transient drowsiness and dizziness.

The results of this trial suggest that baclofen may be useful in treating persistent hiccups in stroke patients. However, further research is needed to confirm these findings.

Hiccups can be caused by a stroke disrupting the breathing centre in the brain

Hiccups can be distressing and sometimes indicate an underlying health issue. In the case of stroke patients, hiccups can be caused by the stroke disrupting the breathing centre in the brain.

A stroke occurs when the blood supply to the brain is interrupted or reduced, and this can happen due to a blocked or burst blood vessel. There are two main types of stroke: ischemic and hemorrhagic. Ischemic strokes are the most common, caused by a blocked artery that leads to reduced blood flow to the brain. Hemorrhagic strokes are caused by the leaking or bursting of a blood vessel in the brain.

The breathing centre in the brain is a complex system involving several groups of interconnected neurons that initiate and control respiratory rhythm. This system is located in the brainstem, specifically in the pons and medulla oblongata regions. When a stroke disrupts this breathing centre, it can lead to a condition called hiccups or "singultus".

Hiccups are characterised by involuntary, intermittent, repetitive contractions of the diaphragm and inspiratory intercostal muscles, which lead to an abrupt closure of the glottis, producing the characteristic "hic" sound. Hiccups can be temporary and benign, but they can also become persistent and intractable, lasting for extended periods and causing significant discomfort and even morbidity.

For stroke patients experiencing persistent hiccups, it is important to identify and address the underlying cause. This may involve a comprehensive medical evaluation, including a detailed history, physical examination, and relevant investigations such as blood work, endoscopy, and imaging studies.

There are both non-pharmacological and pharmacological approaches to managing persistent hiccups in stroke patients:

Non-pharmacological approaches:

• Physical maneuvers such as breath-holding, the Valsalva maneuver, sipping cold water, gargling with water, or pulling the knees to the chest.
• Behavioural therapy and hypnosis have also been successful in some cases.

Pharmacological approaches:

• Chlorpromazine, a dopamine antagonist, has been commonly used to treat persistent hiccups, but it has been associated with serious side effects, including sedation, hypotension, and delirium, leading to the revocation of its approval by the U.S. Food and Drug Administration (FDA) for treating hiccups.
• Baclofen, a GABA-B agonist, has been found to be effective in treating persistent hiccups and is often considered a first-line therapy. It can be started at a dose of 5 mg every 12 or 8 hours and gradually increased up to a maximum daily dosage of 75 mg.
• Other medications that have been used include gabapentin, olanzapine, midazolam, haloperidol, and metoclopramide.
