Most infants admitted to premature baby or neonatal surgical units are nursed in incubators during part of their stay in hospital. There are many advantages of nursing these infants in incubators, but there is also one great disadvantage, the danger of bacterial colonization and contamination inside the incubator. The temperature inside the incubator approaches that of the body and many of thes...

Although hyperbaric oxygen has been shown to enhance the efficacy of radiotherapy and chemotherapy for the treatment of several malignant tumors, the impact of hyperbaric oxygen on osteosarcoma has not yet been demonstrated. In this study, we investigated the efficacy of hyperbaric oxygen alone and in combination with an anti-cancer drug as an adjuvant to chemotherapy. In vitro, highly metastat...

To the Editor, I read with interest the case reported in the Journal describing the events surrounding the death of a child from unilateral blunt chest trauma due to coronary and cerebral arterial gas embolism (AGE). The authors used high frequency oscillatory ventilation (HFOV) for oxygenation with a mean airway pressure of 18 cmH2O because the child’s hemoptysis raised concerns regarding airw...

Five-week-old normotensive Wistar-Kyoto rats (WKY) and spontaneously hypertensive rats (SHR) were subjected to hyperbaric oxygenation with an enhanced atmospheric pressure (950 mmHg) and an increased oxygen concentration (36%) for 6 h per day. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were monitored for 8 weeks of hyperbaric oxygenation period. After 8 weeks of hyperbaric...

We hypothesized that exposure to prolonged recumbency (bedrest), and thus reductions of intravascular pressure gradients, increases pressure distension in arteries/arterioles in the legs. Ten subjects underwent 5 wk of horizontal bedrest. Pressure distension was investigated in arteries and arterioles before and after the bedrest, with the subject seated or supine in a hyperbaric chamber with e...

Use of mild hyperbaric oxygen less than 2 atmospheres absolute (2026.54 hPa) with normal air is emerging as a common complementary treatment for severe muscle injury. Although hyperbaric oxygen at over 2 atmospheres absolute with 100% O2 promotes healing of skeletal muscle injury, it is not clear whether mild hyperbaric oxygen is equally effective. The purpose of the present study was to invest...

Current guidance for survivors aboard a disabled submarine (DISSUB) recommends the use of the "stir-and-fan" method of carbon dioxide (CO2) scrubbing in which the contents of canisters of lithium hydroxide (LiOH) are dispersed onto horizontal surfaces. This technique is objectionable because it releases large quantities of fine, caustic LiOH dust and it utilizes LiOH inefficiently. This report ...
