Intravenous almitrine has been used successfully for short-term improvement of PaO2in patients with acute respiratory failure. [4,5] At low doses (,10 [micro sign]g [middle dot] kg-1[middle dot] min-1), intravenous almitrine alone improves intrapulmonary shunt. [1] Such improvement in PaO2has been attributed to an intrapulmonary blood flow redistribution from the poorly ventilated zones toward the normal zones. [5,6] Such redistribution has been related to a preferential pulmonary vascular contraction in hypoxic zones. The recent development of inhaled therapies, such as nitric oxide (NO) and prostacyclin, to manipulate the flow component of the ventilation-perfusion ratio prompted us and others [7-9] to combine these therapies with almitrine to optimize the PaO2of severely hypoxic patients. However, such improvement in the ratio of PaO2to the inspiratory fraction of oxygen (FIO(2)) might be cosmetic, because most deaths after acute respiratory distress syndrome (ARDS) were related to multiple ...

TY - JOUR. T1 - Almitrine fails to improve oxygenation during one-lung ventilation with sevoflurane anesthesia. AU - Bermejo, Silvia. AU - Gallart, Lluís. AU - Silva-Costa-Gomes, Teresa. AU - Vallès, Jordi. AU - Aguiló, Rafael. AU - Puig, Margarita M.. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Objective Almitrine enhances hypoxic pulmonary vasoconstriction (HPV) and can improve hypoxemia related to one-lung ventilation (OLV). Studies using almitrine have been conducted without inhaled anesthetics because they could inhibit HPV, counteracting the effect of almitrine. This hypothesis, however, has not been confirmed. This studys aim was to evaluate whether almitrine could improve oxygenation when administered during OLV with sevoflurane anesthesia. Design A prospective, randomized, double-blind, placebo-controlled trial. Setting A tertiary care, university teaching hospital. Participants Thirty adult patients undergoing open-chest thoracic surgery. Interventions Patients were assigned randomly to ...

1. To test whether almitrine might improve the arterial partial pressure of O2 in patients with chronic obstructive airways disease by improvement of ventilation-perfusion matching, we looked at the interaction between hypoxic and almitrine-induced vasoconstriction in isolated rat lungs perfused with blood at constant flow. Increases in pressure represented increases in resistance.. 2. Almitrine, given in increasing doses between challenges with 2% O2, enhanced hypoxic vasoconstriction at low doses but attenuated it at high doses.. 3. Stimulus-response curves to hypoxia of increasing severity gave a sigmoid curve.. 4. Almitrine solvent caused small changes in pulmonary artery pressure and shifted the stimulus-response curve slightly in a parallel fashion.. 5. Small doses of almitrine enhanced the action of mild to moderate hypoxia, medium doses attenuated moderately severe hypoxia, whereas high doses depressed vasoconstriction due to all degrees of hypoxia.. 6. These effects of almitrine on ...

The plasticity of synaptosomal non-mitochondrial ATPases was evaluated in cerebral cortex from 3-month-old normoxic rats and rats subjected to either mild or severe intermittent normobaric hypoxia [12 hr daily exposure to N2:O2 (90:10 or 91.5:8.5) for four weeks]. The activities of Na+, K(+)-ATPase, low- and high-affinity Ca(2+)-ATPase, Mg(2+)-ATPase, and Ca2+,Mg(2+)-ATPase were assayed in synaptosomes and synaptosomal subfractions, namely synaptosomal plasma membranes and synaptic vesicles. The evaluations were performed after a 4-week treatment with saline (controls) or alpha-adrenergic agents (delta-yohimbine, clonidine), a vasodilator compound (papaverine), and an oxygen-partial pressure increasing agent (almitrine). These treatments differently changed the adaptation to chronic intermittent hypoxia characterized by a decrease in the activity of Na+,K(+)-ATPase, Ca2+,Mg(2+)-ATPase, and high-affinity Ca(2+)-ATPase, concomitant with a modification in the activity of Mg(2+)-ATPase supported in ...

For this study, researchers selected the gastrodine compound granule. It s extracted from tall gastrodia tuber plants and six other herbs and is the first of new herbal drugs in dementia to be tested in clinical trials. The 12-week, randomized, double-blind trial was done in Beijing Dongzhimen Hospital, one of the hospitals running the clinical trials between 1999 and 2002. Researchers identified 120 stroke patients (75 male 45 female) who were diagnosed with mild to moderate VaD lasting three months or more. All patients were assessed for VaD at baseline and randomly divided into two treatment groups. One group (70 patients) was given one bag of the gastrodine compound granule (2.6 milligram gastrodine) three times a day for 12 weeks. The second group (50 patients) was given 40 mg of Duxilâ (almitrine + raubasine) three times a day for 12 weeks. This is a drug used to treat stroke patients in China. Both the gastrodine compound granule and the Duxilâ granule were dissolved in hot water and ...

30. Baker concluded that Barrett suffers a moderate impairment and lacks the respiratory capacity to perform the work of a coal miner or comparable work in a dust-free environment. J.A. at 120. The ALJ noted that Bakers opinion was based not only on the March 28, 2000 pulmonary function test, which was determined to be invalid, but also on a subsequent pulmonary function test that did produce qualifying results and on arterial blood gas studies which indicated that Barrett had mild resting arterial hypoxemia. J.A. at 222. The ALJ concluded that, [w]hile the weight of the valid and conforming pulmonary function tests alone constitutes probative evidence of total disability, when combined with the arterial blood gases, which provide no evidence of total disability, and the medical opinions, which weigh in favor of a finding of total disability, the weight of the evidence directs a finding of total disability. J.A. at 223. In rejecting Dr. Dahhans opinion to the contrary, the ALJ noted that ...

Doxapram hydrochloride (marketed as Dopram, Stimulex or Respiram) is a respiratory stimulant. Administered intravenously, doxapram stimulates an increase in tidal volume, and respiratory rate. Doxapram stimulates chemoreceptors in the carotid bodies of the carotid arteries, which in turn, stimulates the respiratory centre in the brain stem. Doxapram is a white to off-white, odorless, crystalline powder that is stable in light and air. It is soluble in water, sparingly soluble in alcohol and practically insoluble in ether. Injectable products have a pH from 3.5-5. Benzyl alcohol or chlorobutanol is added as a preservative agent in the commercially available injections. Doxapram is used in intensive care settings to stimulate the respiratory rate in patients with respiratory failure. It may be useful for treating respiratory depression in patients who have taken excessive doses of drugs such as buprenorphine or fentanyl analogues which may fail to respond adequately to treatment with naloxone. It ...

Thank you for your interest in our paper and for your comments. As was correctly pointed out in the letter, patients who are kept NPO should be given IV glucose supplementation. This was not done for our patient and this is indeed one of the reasons we decided to present her case in the Learning from errors section of the journal. We would like to clarify that it is in fact very unlikely for a non- breastfeeding patient to become significantly acidotic secondary to having no caloric intake for three days. Our bodies are normally well equipped to deal with short term starvation and only mild levels of acidosis develop in the starvation state when insulin levels are normal. In a small study published by Reidenberg et al., obese (non-lactating) women were starved for over a month and this produced only a mild metabolic acidosis of approximately 7.35 on arterial blood gas analysis. 1 On the other hand, Mohammad et al. showed that when lactating women are fasting for more than 42 hours, they begin to ...

Amiphenazole (Daptazile) is a respiratory stimulant traditionally used as an antidote for barbiturate or opiate overdose, usually in combination with bemegride,[1][2] as well as poisoning from other sedative drugs[3][4] and treatment of respiratory failure from other causes.[5] It was considered particularly useful as it could counteract the sedation and respiratory depression produced by morphine but with less effect on analgesia.[6][7] It is still rarely used in medicine in some countries, although it has largely been replaced by more effective respiratory stimulants such as doxapram and specific opioid antagonists such as naloxone.[8][9] ...

Chronically low blood levels of oxygen may lead to pulmonary hypertension (high blood pressure in the arteries of the lungs), and possibly to cor pulmonale. Cor pulmonale is also called right-sided heart failure, and is characterized by enlargement of the right ventricle. Treatment targets the underlying illness and may include supplemental oxygen, a low-salt diet or diuretics (water pills ...
