What Are the Pros and Cons of Hyperbaric Oxygenation Therapy?

Hyperbaric oxygen medicine is an emerging discipline in clinical medicine, with its unique curative effect and broad development prospects. The method of treating patients with certain conditions by absorbing pure oxygen through a hyperbaric oxygen chamber to treat patients in an environment above atmospheric pressure is called hyperbaric oxygen therapy. The concentration of oxygen absorbed is 85% to 99%. The blood oxygen content is several times or even dozens of times the oxygen absorption under normal pressure. It can effectively increase blood oxygen tension and increase blood oxygen content. It is useful for the treatment of some acute and chronic deficiencies. Oxygen diseases have their special effects. ^[1]

1. As the main treatment method, HBO has been widely used in clinical practice and has proved to have significant effects: acute carbon monoxide poisoning; acute decompression sickness; acute embolism; asphyxia (smoke, drowning, self-contamination, accidental anesthesia, etc.); gas gangrene; Traumatic brain injury and post-injury brain dysfunction (brain contusion, cerebral hematoma removal, concussion, traumatic brain injury syndrome, etc.); harmful gases (hydrogen sulfide, alkanes, chlorine, ammonia, phosgene, etc.) and cyanide Chemical poisoning; acute fundus blood supply disorders; elevated intracranial pressure caused by surgery or other causes of acute cerebral edema; carbon monoxide poisoning delayed encephalopathy.

2. HBO, as one of the comprehensive treatment measures, can significantly improve the efficacy of the diseases: after limb replantation (including finger and toe) and acute peripheral circulation disorders; skin (skin, flap, etc.) before and after transplantation; brain deficiency Bloody disease

The following conditions are generally taboo for HBO:

Open chest wall trauma, multiple rib fractures, extensive and severe chest wall contusions;

After clinical follow-up studies of hundreds of patients, high-pressure anion oxygen therapy:

1. Promote gas dispersion, improve hypoxia more quickly, remove carbon dioxide more quickly, and correct respiratory failure more effectively.

2, change the breathing pattern, reduce breathing resistance, make breathing easier and save effort.

3. The structure of helium-oxygen gas is stable, the pressure is uniform, and the treatment is safer and more reliable.

4. Quickly relieve spasm and asthma

5, can effectively inhibit

1. Eliminate fatigue, improve intelligence and work efficiency

The human brain consumes 20% of the body's oxygen and is particularly sensitive to hypoxia. Insufficient oxygen can cause physical insufficiency, lack of energy, dizziness, insomnia, memory loss, and loss of appetite, etc.

Operation of multi-aerobic cabin

1. Each

1. After each treatment, after the patient leaves the cabin, in addition to the patient's condition inquiry and necessary inspections, the oxygen chamber and related devices should be checked and disinfected as necessary to prepare for the next use.

2. The number of patients entering the cabin for treatment must be strictly controlled, calculated on the basis of the per capita occupied capacity, and must not be lower than the per capita capacity specified in the national standard (GB-12130-1995).

3 The oxygen concentration in the oxygen chamber pressurized with air must be strictly controlled within 25%.

Complications and their prevention

1. All outpatients who want hyperbaric oxygen (HBO) treatment need to be examined by an outpatient HBO specialist, confirmed with indications for HBO treatment, and excluded from HBO treatment contraindications before they can go to the HBO department (room) by appointment time treatment.

2. Inpatients of HBO department (room) need to be examined by an outpatient HBO specialist, and then implemented according to the general routine work of internal medicine admission.

3 Other patients who need HBO treatment should be consulted by a HBO physician to determine the indications for HBO treatment, and then go to the HBO department (room) for treatment at the agreed time.

4 Patients from outside hospitals must first submit a consultation sheet and related medical records and examination data. After consultation with the HBO physician and confirmation of the HBO indication, they can be transferred to outpatient treatment or transferred to the HBO department (room) for inpatient treatment.

5. Patients with acute, critical, or severe illness must notify the HBO department (room) in a timely manner by the emergency department (room) or the department where they are located. The HBO physician will consult to determine whether emergency HBO treatment is needed.

6. In general, before routine HBO treatment, patients should undergo routine physical examinations, chest radiographs, and eustachian tube ventilation function tests (usually the eustachian tube and eustachian tube ventilation method). According to the needs of the disease, ECG, EEG, brain topography, electrical audiometry, pulmonary function measurement and brain CT, SPECT or MRI and other special examinations can be added to confirm the diagnosis and observe the curative effect.

7. The patient is critically ill and cannot take care of himself. The patient needs to be observed at any time, or the operator who needs to perform diagnosis and treatment in the cabin. He or she should be accompanied by the medical staff of the HBO department (room) or the medical department of the patient's department (room) to enter the cabin. The cabin is properly handled according to the condition.

8. For patients receiving HBO treatment, the HBO physician will formulate a treatment plan (including treatment pressure, oxygen inhalation method and time, rate of decompression and decompression, etc.), the number of treatments or courses of treatment, and the need to Tell patients about reactions and precautions.

9. During HBO treatment, the HBO physician should make detailed enquiries and necessary physical examinations before the patient enters the cabin, during the treatment in the cabin, and after the departure of the cabin, so as to judge the efficacy and the occurrence of complications. This determines whether a modification of the treatment plan or other ancillary measures is needed.

10 During the treatment period, any cold, fever, and blood pressure above 21 / 13kPa (160 / 100mmHg), middle ear barotrauma, earache, menstrual cramps, or other discomfort should be dealt with as appropriate.

11. After the end of each course of treatment, the physician in charge of treatment should make a treatment summary and judgment of the effect in time to determine whether to continue or end the treatment of HBO, and record the results in the medical record for storage.

12. The operator of the oxygen cabin should strictly implement the compression treatment plan formulated by the HBO specialist and carefully record various parameters during the implementation process, closely observe the changes in the oxygen concentration in the cabin, and strictly control the oxygen concentration within 25%. Ventilation should be reduced immediately to ensure the safe operation of the oxygen tank.

13. During the treatment, the cabin crew must stick to their posts, and must not leave the console without authorization, and closely observe the various conditions in the cabin. If any abnormality occurs, they should report to the doctor in time and take necessary treatment. After the treatment is completed, sign the flight record.

14. HBO medical and nursing staff should perform regular pressurization exercises, each person should be no less than 2 times a month, and do a good job in medical protection according to regulations. And regular physical examination (including shoulder, elbow, knee, hip and other large joint imaging examination).
