  • The purpose of this study is to evaluate the reliability and effectiveness of hyperbaric oxygen chamber on alcohol-induced oxidative stress and hangover. In order to evaluate them, 20 healthy adults were tested for blood and hangover stress tests. When an exponential change was examined after 3 interventions (hangover drink, hyperbaric oxygen chamber, and normal chamber as placebo effect) of 1 hour, the heart rate of subjects experiencing a hyperbaric oxygen chamber showed a statistically significant decrease (p < 0.001). The tests of blood alcohol concentration (BAC) as for exquisite hematology analysis, glucose, creatinine, and AST (aspartate aminotransferase) as well as ALT (alanine aminotransferase) used as liver-damage indicator show that the hyperbaric chamber has the effective effect. In the test of lactic acid, CRP (c-reactive protein), cortisol, and creatinine, the hyperbaric chamber shows much more excellent effect than the hangover drink and normal chamber as control groups. Further studies on hyperbaric oxygen chamber intervention including this study could be very helpful for improving lives of both the patients and healthy people.

  • Purpose: The aim of this study is to investigate current status, indications, and complications of hyperbaric oxygen therapy. Methods: A retrospective investigation of patients who underwent hyperbaric oxygen therapy at a university medical center from September 2004 to August 2013 was conducted based on patients' medical records and results of an email survey for 99 emergency centers. Results: During the study period, a total of 233 patients underwent hyperbaric oxygen therapy. Indications for hyperbaric oxygen treatment of illness or injury were as follows: 1) 151 cases of acute carbon monoxide poisoning(65.4%), 2) flap wound management, including 42 cases(18.2%), 3) skin care transplanted, including 23 cases(10.4%), 4) Burger's disease, including 5 five cases(2.1%), respectively. Total application time$^*$ frequency was 1,088 and total time was 1,239 hours. Among 233 patients who underwent hyperbaric oxygen therapy, 32 patients(13.7%) had complications: 1) otalgia in 21 cases(9.0%), 2) mastoiditis?in six cases(2.6%), 3) hemotympanum in five cases(2.1%), respectively. There were only 8 emergency centers that currently had an operational hyperbaric oxygen chamber in 77 emergency centers(10.4%). Conclusion: Indications identified through this study showed difference from current indications worldwide. It seems necessary that physicians' perception regarding application of hyperbaric oxygen therapy for more indications be changed and improved. A hyperbaric chamber capable of providing respiratory assistance and intensive care is also needed. A good network for sharing treatment experiences and a specialized team for administration of hyperbaric oxygen therapy is also required.

  • Carbon monoxide poisoning is one of the most serious health problems in Korea, because we have been encountered with the highest incidence of CO poisoning in the world due to the unique heating system in home called 'ondal'. We opened Hyperbaric chamber unit in the Seoul National University Hospital last Jan, 1969. We have treated 848 patients as of Sept. 30., 1972, around 44 months period. We collected the informations on the environmental conditions of the place where CO intoxication actually occured by filling up the questionaire from 505 patients. The following findings were obtained. 1. Age distribution showed that the highest incidence was found in the younger age group between age of 10 to age of 29 in both sex. 2. Sex ratio of the patients was 1:1.14. 3. The socio-economic level of the patient was relatively low. 4. Housewife & housemaid were the major victims of the intoxication in the female patients & in the case of the male patient, occupational backgrounds were diverse. 5. Many patients from the middle class experienced the intoxication by sleeping at newly built room. 6. Many intoxication has been occured in the structure of houses where communicating doors are existing between living room & kitchen. 7. All findings obtained taught us again that CO poisoning is the serious by-product of the national fuel policy which put emphasis on the use of coal & socio-economic status is a very important parameter in this hazards.

  • 본 논문에서는 환자의 산소 민감도와 선호패턴을 고려하여 개인별 산소치료 프로파일을 지정하고, 여기에 따라 자동적으로 시간별 산소압을 조정하여 제공하는 3단 분리형 단격실 산소챔버를 설계한다. 고압산소치료는 대기압보다 높은 100% 산소를 환자에게 제공하는 방법으로 개인에 따라 기압차에 따른 귀의 통증을 호소하는 단점이 있었다. 제안 시스템은 임베디드 시스템을 기반으로 환자의 산소치료 선호패턴 및 치료기록을 DB화하여 환자 맞춤형 산소치료 프로파일을 작성하고, 환자의 이름만 입력하면 산소챔버가 자동적으로 작성된 프로파일 패턴에 따라 산소압을 자동적으로 조정함으로써 산소치료 효과를 극대화 할 수 있다. 향후 관리자의 스마트폰과 연동하여 작동하는 산소챔버용 원격관리 시스템으로 확장함으로써 관리의 용이성 및 산소치료의 안전성을 제고하고 부가가치를 극대화 할 수 있기를 기대한다.

  • Experimental studies were performed to observe the difference in tolerance of small animals to oxygen poisoning, and also to examine the effects of certain drug for it. The three experimental groups consisted of mature rat group, immature rat group and mouse group. The animals were exposed to 5 atm. of 100% oxygen using hyperbaric chamber, and they were observed for oxygen poisoning by pulmonary and central nervous system manifestation. The tolerance to oxygen poisoning was represented by half fatality time in each experimental group. The drug applied was ammonium chloride $NH_4Cl$ and it was administered intraperitoneally in various dosages for particular attribution of its prophylactic effect. The following conclusions were made; 1. The immature rat group showed the higher degree of tolerance to oxygen poisoning, as evidenced by a more prolonged half fatality time in the group. No significant difference in the half fatality time between the mature rat and the mouse group was observed. 2. The fact that the immature group showed the higher degree of tolerance as compared with the mature rat group represented by delayed onset of convulsion. 3. There was a remarkable difference in the Lung Weight/Body Weight ratio between the experimental and control group. 4. The animals with a shorter half fatality time uniformally displayed an earlier onset of convulsive seizure as the sign of oxygen poisoning and a significant elevated Lung Weight/Body Weight ratio. 5. Ammonium chloride at the dosage of 450mg per kg body weight had the most pronounced prophylactic effect on oxygen poisoning.

  • The ultimate goal of treatment of carton monoxide poisoning is to promote dissociation of carboxyhemoglobin and to maintain arterial $PO_2$ above 50mmHg throughout the course of treatment to protect vital organs from damage caused by hypoxia. The hyperbaric chamber designed and manufactured for this purpose has obviousely made an enormous contribution and yet has several handicaps to be overcome by any means. These handicaps are: the financial impact to purchase the chamber (especially in a small, remote community), an extra manpower requirement to operate the device, limitation in the capacity of the chamber (one man type), and the possible hazard of oxygen intoxication and dysbarism. The primary objective of this study is to develope a new therapeutic measure as an alternative to the hyperbaric chamber when it is not available or contraindicated. The effect of intestinal perfusion with hydrogen peroxide has been studied by many investigators and was known to be an excellent way of extrapulmonary oxygen supply. the advantage of this method will include; 1) much more amount of oxygen is delivered to the tissue than one would expect from 100% saturation with oxygen at 1 ata, 2) the procedure is simple and most economical, 3) neither sophisticated equipment nor extra manpower is required. As a study preliminary to the clinical application, authors conducted a series of experiment to observe the effect of hydrogen peroxide enema on dissociation of carboxyhemoglobin in intoxicated rabbit blood. Using an animal gas chamber, 20 rabbits were exposed to CO gas of 6,000 ppm for 60 minutes. Ten rabbits of control group were given 10cc of warmed normal saline solution by reactal perfusion and for the other 10 of the experimental group, the same amount of 1% $H_{2}O_{2}$ solution was given by the same way. Two blood specimens were drawn from each rabbit: the first one immediately following the exposure and the second one after rectal perfusion, about 30 minutes after the first sampling. The result was as follows; 1) The decrease in carboxyhemoglobin concentration during the first 30 minutes in the control and experimental group were $18.18{\pm}4.49%\;and\;23.03{\pm}4.13%$ respectively shelving the significant difference (p<0.05) between the two groups. 2) Hemoglobin and hematocrit value showed no significant difference between two groups and not altered significantly by intestinal perfusion with $H_{2}O_{2}$.

  • Hyperbaric oxygen therapy(HBO) is defined as breathing 100% oxygen while in an enclosed system pressurized to greater than on atmosphere(sea level). This increased oxygen delivery furthers your body's ability to kill germs and to increase healing. HBO is a supplemental therapy to be used in addition to the current medical and surgical therapy you are receiving. HBO typically is used to complement treatments of medical problems such as bone infections, complication of radiotherapy, and certain chronic, non-healing wounds. On an emergency basis, the chamber also is used to treat problems such as carbon monoxide poisoning and the decompression sickness. We analysed stastically cases which are treated by hyperbaric oxygen therapy in point of oral and maxillofacial region on the Kangnam General Hospital for aid in comprehension and application of this therapy. Total 760 patients were treated at Gangnam General Hospital from July 1996 to September 1999. They were classified by region to Decompression sickness(DCS), Carbon monoxide poisoning(CO), General surgery(GS), Orthopedics(OS), Oral and Maxillofacial surgery(OMFS), others. Patients of Oral and Maxillofacial surgery were divided by diseses to Osteomyelitis, Osteoradionecrosis, Reconstruction, Bone graft, Difficult wounds, others. The results were as follows. 1. This institute conducts HBO therapy for DCS which takes up 62% and 10.5% for OMF region. 2. In OMF region, Osteomyelitis is 40%, Osteoradionecrosis is next, Bone graft, and Reconstruction is a row. 3. According to our precious study, HBO has been frequently conducted in OMF region compared to past, however, it is less actively conducted in this area for research than other conturies. Therefore, We need further application to the clinical use.

  • 재난 시 피해자를 위해 사용되는 고압산소치료 시 흔한 부작용으로 높아진 압력에 적응하지 못하고 귀의 통증을 비롯한 압력 손상의 증상이 발현되는 경우가 종종 존재하여 이는 고압산소치료 시 해결해야 할 과제로 떠올랐다. 이에 본 본 연구에서는 고압산소치료기에 개발된 압력손상방지장치를 연결하여 적용하였을 때 고압산소치료 중 압력손상이 조기 감지되고 이를 통해 고압산소치료를 받는 피해자가 압력손상이 진행되지 않는지에 대하여 연구하였다. 압력손상방지장치를 활용하면 고압산소치료 중 압력손상이 조기 감지되고 이를 통해 고압산소치료를 받는 피해자가 압력손상이 심하게 진행되지 않는데 도움을 받을 수 있다. 단 이는 피해자 본인이 체내압력 조절이 가능한 상태여야 하며 의식이 없거나 협조가 어려운 대상에 대한 압력손상방지는 또 다른 도전으로 향후 이에 대한 추가적 연구가 필요하다.
