1. Preface

Ischemic stroke, also known as cerebral infarction, is a localized necrotic lesion of brain tissue caused by a narrowing or occlusion of the blood supplying arteries to the brain that triggers insufficient blood supply to the brain [1]. Ischemic stroke has a high morbidity and mortality rate and a poor prognosis, and it often occurs in middle-aged and elderly people [2]. In recent years, with the change of people’s lifestyle, the number of cases has been increasing year by year, which seriously threatens the physical and mental health of patients. Ischemic stroke is caused by obstruction of cerebral blood flow and the pathophysiological changes of ischemia, hypoxia, and necrosis of the brain parenchyma, which in turn impairs cognitive and other neurological functions of the patient. The current treatment modalities for ischemic stroke mainly focus on thrombolysis, anticoagulation, and reduction of blood viscosity [3, 4]. Some ischemic stroke patients are often accompanied by varying degrees of anxiety and depression, which seriously affect the patient’s sleep quality and is very unfavorable for the patient’s treatment and recovery [5]. Dexzopiclone is a common sedative-hypnotic drug commonly used for various types of insomnia symptoms [6]. Sertraline is a commonly used antidepressant and anxiety drug in clinical practice, which can effectively relieve the bad psychological state of patients and contribute to the sleep quality of patients [7].

In addition to the above treatment, how to improve the patient’s neurological impairment, restore the patient’s motor function, and improve the patient’s prognosis is also the focus of clinical attention. Hyperbaric oxygen therapy (HOT) is currently an effective way to promote the prognosis of patients with ischemic stroke, which can effectively increase the oxygen acquisition of brain tissue by inhaling high concentrations of oxygen, thereby promoting the recovery of injured neurological functions, improving blood circulation, enhancing brain metabolism, and contributing to the recovery of neurological functions [8, 9]. In this study, hyperbaric oxygen was used to treat patients with sleep disorders after ischemic stroke, and its effects on sleep quality, drug dosage, and neurological function were analyzed. The reports are as follows.

2. Materials and Methods

2.1. General Information

From January 2019 to October 2021, 120 patients with acute ischemic stroke sleep disorder who came to our hospital for treatment were selected as research subjects. According to the random numbering method, they were divided into the control group and observation group, with 60 cases in each group. There was no statistical difference in the data between the two groups (), Table 1.

Diagnostic criteria: (1) focal neurological deficits and, in a few cases, global neurological deficits; (2) unlimited duration or persistence of symptoms or signs for more than 24 h; (3) exclusion of vascular causes; (4) exclusion of cerebral hemorrhage by cranial CT or MRI.

Inclusion criteria: (1) The diagnostic criteria for ischemic stroke were met [10], and confirmed by head CT or MRI; (2) Had not taken similar drugs or drugs antagonistic to this drug recently; (3) All patients were first-time patients stroke patients; (4) informed and voluntary participation. Exclusions: (1) Patients with malignant tumors; (2) Mental disorders, unable to communicate normally; (3) Poor compliance. (4) Complicated with organic diseases such as heart, liver, and kidney.

2.2. Methods

2.2.1. The Control Group Was Given Conventional Treatment

The patient was hospitalized immediately after diagnosis, and given normal pressure oxygen inhalation, intracranial pressure reduction, antiplatelet drugs, thrombolysis, neurotrophic solution, symptomatic and supportive treatment, etc. Aspirin enteric-coated tablets (Shenyang Aojina Pharmaceutical Co., Ltd., approved by H20065051, 100 mg/time, once/d) and nimodipine (Hubei Sihuan Pharmaceutical Co., Ltd., approved by H20030026, 60 mg/time, 2 times/d) were given for the treatment of ischemic stroke. Critically ill patients were given drugs to prevent infection, antiarrhythmia and maintain water-electrolyte balance, sedation and antiepilepsy according to the patient’s symptoms, as well as appropriate rehabilitation instructions for two consecutive weeks.

2.2.2. The Observation Group Received Hyperbaric Oxygen Therapy on the Basis of the Control Group

The patients in the observation group started to receive hyperbaric oxygen therapy after the vital signs stabilized on the 3rd day of admission. A single hyperbaric chamber was used, with partial pressure of oxygen at 2.0 mPa, pressurized to 0.2 Mpa, and stabilized for 20 min. The chamber was washed at high flow rate for 10 min at the high pressure plane, and then gradually decompressed and discharged, 60 min/time, 1 time/d, for two weeks, and early rehabilitation training was also instructed.

2.2.3. Treatment Options for Sleep Disorder Medications

The two groups of patients were given the same sleep drug sertraline (Pfizer Pharmaceutical Co., Ltd., approved by the State Drug H10980141, 50 mg30 tablets) and dexrazopiclone (Jiangsu Tasly Diyi Pharmaceutical Co., Ltd., approved by the State Drug H20070069, 3 mg6 tablets) for the treatment of sleep disorders. Dexrazopiclone 3 mg/d, 1 time/d and sertraline 50 mg/d, 1 time/d were started and the dose was adjusted according to the patient’s sleep status.

2.2.4. Observation Indicators

(1)To compare the sleep quality of the two groups of patients before and after treatment. All patients were evaluated by specialized medical staff within 24 hours of admission and were collected by a sleep disorder scale. The Pittsburgh Sleep Quality Index Inventory (PSQI) was used to assess sleep quality, consisting of 7 factors (sleep quality, time to fall asleep, sleep duration, sleep efficiency, sleep disorder, hypnotic medication, and daytime function), with a total score range of 0–21. A total PSQI score ≥7 can be used as a criterion for diagnosing sleep disorders, and a higher score indicates poorer sleep quality. Epworth (ESS) was used to evaluate the degree of daytime sleepiness, and the ESS scale consisted of 8 items, each item was scored 0∼3 (never napping was scored as 0, rarely napping was scored as 1, sometimes napping was scored as 2, and often napping was scored as 3), and the total score was 24, ESS>10 was assessed as daytime sleepiness, the higher the score, the more serious the patient’s sleepiness. The STOP-Bang questionnaire (SBQ) was used to assess sleep apnea, which included whether snoring was loud, whether daytime fatigue was present, whether sleep apnea was observed, whether hypertension was present, and gender, age, BMI, and neck circumference. The presence of sleep apnea was determined by an SBQ score ≥3.(2)To compare the dosage of sleep drug sertraline before and after treatment in the two groups of patients.(3)The serum levels of tumor necrosis factor-α (TNF-α), endothelin (ET), and neuropeptide Y (NPY) were compared between the two groups of patients before and after treatment. 8 mL of fasting venous blood was collected from patients, centrifuged at 3500 r/min for 10 min at 5°C, and the upper layer of plasma was stored in a refrigerator at −40°C and assayed by radioimmunoassay technique.(4)Comparison of the changes of neurological function between the two groups before and after treatment. NIHSS was used to evaluate the neurological function of the patients. The scores included the level of consciousness, language, articulation, movement of limbs, sensation, and facial paralysis.

2.2.5. Statistical Analysis

Statistical software SPSS 22.0 was used to analyze the data. The count data was expressed as rate, and the χ² test was used. The measurement data was expressed as (), and the t-test was used. was considered statistically significant.

4. Discussions

Ischemic stroke is a common clinical cardiovascular and cerebrovascular disease, and patients are often accompanied by varying degrees of sleep disorders, which affect the recovery process of patients and are not conducive to the improvement of prognosis [11]. Patients have various forms of sleep disorders, including difficulty in falling asleep, insomnia, and sleep apnea. Long-term sleep disorders can lead to poor mental concentration, daytime sleepiness, anxiety, and depression [12]. At present, sleep disorders are generally treated with drugs, but long-term use of drug therapy can produce toxic side effects on the body [13], HOT is a noninvasive treatment method and is widely used in neurology [14]. In this study, HOT was used to treat ischemic stroke patients with sleep disorders, in order to improve the sleep quality of patients, reduce the dosage of sleep drugs, and improve the neurological function of patients.

In this study, it was found that the levels of TNF-α, ET, and NPY were not significantly different between the two groups before treatment, and the levels of these indicators decreased in both groups after treatment, and the observation group was significantly lower than the control group. TNF-α is a tumor necrosis factor with strong biological activity, which can activate leukocytes and promote the release of various inflammatory mediators; ET has a vasoconstrictive function and can be released in large quantities in a state of ischemia and hypoxia, and is an endogenous injury-causing factor. NPY is a neuropeptide that is widely distributed in the central and peripheral nervous systems and can stimulate the occurrence of inflammatory responses [15]. The reduction of inflammatory factors such as TNF-α, ET, and NPY after treatment suggests that hyperbaric oxygen therapy contributes to the clearance of serum inflammatory factors in ischemic stroke, reduces the inflammatory response, and improves cerebral blood circulation. HOT can improve patients’ cerebral hypoxia, increase the partial pressure of blood oxygen in cerebral vessels, promote cerebral blood circulation, improve cerebral metabolism, reduce intracranial pressure, alleviate cerebral edema, accelerate the rate of removal of oxygen free radicals and inflammatory factors in the body, and reduce their secondary damage to the brain tissue [16]. It was found that there was no significant difference in the scores of PSQI, ESS, and SBQ between the two groups before treatment, and the scores of the above scales decreased in both groups after treatment, with the observation group significantly lower than the control group, and the use of sleep medication in the observation group was significantly lower than the control group after treatment. PSQI, ESS, and SBQ are common clinical scales used to assess patients’ sleep quality, and the results of the study showed that adding hyperbaric oxygen therapy to conventional treatment can improve patients’ sleep quality and reduce dependence on sleep medication.

The pathogenesis of sleep disorders in patients with ischemic stroke is complex. In recent years, there have been many studies [17, 18] on the pathogenesis of sleep disturbance after ischemic stroke at home and abroad, and it is believed that the neurons in the brain may be damaged, the brain edema compresses the surrounding brain tissue, and the brain areas involved in sleep regulation are severely damaged, blocking the conduction of the specific reticular upward activation system, thus triggering the disruption of sleep structure. HOT can improve the state of brain hypoxia, increase the blood oxygen content of brain tissue, restore blood supply balance, improve the state of intracranial hypertension, accelerate the scavenging of free radicals, reduce secondary damage to brain tissue, eliminate the vicious cycle of brain tissue hypoxia-edema-hypoxia, can promote the reconstruction of deficient neurological function, and improve the quality of sleep [7, 19]. At the same time, hyperbaric oxygen therapy reduces the inflammatory response of the blood vessels in the brain, decreases the interference of neuropathic factors in the sleep of patients, improves the quality of their sleep, reduces dependence on drugs, and decreases the use of drugs [20]. NHISS scores decreased in both groups before and after treatment compared with those before treatment, and were lower in the observation group. The possible reason for the analysis is that insufficient energy metabolism of brain cells due to severe ischemia and hypoxia is the main cause of triggering neurological function damage, while HOT can rapidly increase the oxygen content of blood, improve hemodynamics, promote oxygen metabolism of brain cells, accelerate the regeneration and repair of capillaries, help the recovery of the internal environment of damaged neurons, and reduce the damage to patients’ neurological function [21].

In conclusion, the treatment of patients with sleep disorders after ischemic stroke with HOT on the basis of conventional treatment has good efficacy, can significantly improve the sleep quality of patients, reduce the use of sleep medication, high safety, reduce the inflammatory level of brain tissue, improve the neurological impairment of patients, and is worthy of clinical promotion.
