Children with asthma If reversal of bronchospasm is incomplete after the first nebulisation:  Prednisone buy 200 mg floxin free shipping, oral 400 mg floxin otc, 1–2 mg/kg immediately then once daily for 7 days Weight Dose Tablet Age kg mg 5 mg months/years >11–14 kg 20 mg 4 tablets >2–3 years >14–17 purchase floxin 200 mg overnight delivery. In susceptible patients, exposure to various environmental triggers, allergens or viral infections results in inflammatory changes, bronchospasm, increased bronchial secretions, mucus plug formation and, if not controlled, eventual bronchial muscle hypertrophy of the airways’ smooth muscle. Asthma varies in intensity and is characterised by recurrent attacks of: » wheezing, » dyspnoea or shortness of breath, » cough, especially nocturnal, and » periods of no airways obstruction between attacks. Acute attacks may be caused by: » exposure to allergens, » respiratory viral infections, » non-specific irritating substances, and » exercise. Asthma must be distinguished from chronic obstructive pulmonary disease, which is often mistaken for asthma. The history is a reliable diagnostic guideline and may be of value in assessing treatment response. Note: Initiating and optimising inhalation corticosteroid therapy for moderate and severe asthma should always be done with the use of a peak flow meter to assess severity and treatment response of asthma. M I L D I N T E R M I T T E N T A S T H M A » ≤ 2 episodes of daytime cough and/or wheeze per week » ≤ 1 night-time cough and/or wheeze per month 17. Spacer devices » Spacers are vital for an adequate therapeutic effect of inhaled therapy. Spacer volume Face mask Infants 150–250 mL mandatory Children 500 mL highly recommended Adolescents and adults 750 mL » Inhalation spacer devices enable parents to administer inhaled therapy even to small children. Patient and caregiver education on inhaler and spacer techniques: » A mask attachment should be used with the spacer for children < 3 years of age. Adequate control is defined as: » ≤ 2 episodes of daytime cough and/or wheeze per week. If control is inadequate: » check adherence and inhaler technique, and » exclude on-going exposure to allergens. After excluding those causes, refer to a doctor to confirm the diagnosis of asthma, 17. Once the diagnosis is confirmed, step-up treatment as follows: Children Inhaled corticosteroids, e. It is caused by viral infections and presents with lower airways obstruction due to inflammation and plugging of the small airways. If no response  Epinephrine (adrenaline) 1:1000, 1 mL diluted in 2–4 mL of 3–5% sodium chloride, nebulised over at least 3 minutes, single dose (Doctor initiated). Warn the caregiver that there may be a relapse and advise them to return the patient promptly. Due to the large reserve capacity of the lungs, patients often present when there is considerable permanent damage to the lungs. In addition to the symptoms listed above, patients may present with symptoms or signs of right heart failure. A clinical diagnosis of viral croup can be made if a previously healthy child develops progressive inspiratory airway obstruction with stridor and a barking cough, 1–2 days after the onset of an upper respiratory tract infection. Suspect foreign body aspiration if there is a sudden onset of stridor in an otherwise healthy child. Suspect epiglottitis if the following are present in addition to stridor: » very ill child » drooling saliva » high fever » unable to swallow » sitting upright with head held erect Assessment of the severity of airway obstruction and management in croup Grade 1  Prednisone, oral, 1–2 mg/kg, single dose. Grade 2  Prednisone, oral, 1–2 mg/kg, immediately as a Inspiratory and expiratory single dose. Inspiratory and expiratory » If no improvement within one hour, refer stridor with active expiration, urgently (intubate before referral if possible).

Additionally discount floxin 400mg on-line, such an approach has democratic benefts order 200mg floxin with amex, in that it allows for greater civil society involvement in policy development order floxin 400mg online. It also goes some way to removing the fear that all drugs would somehow just become available ‘overnight’. By demonstrating that policy is being developed in a responsible and cautious fashion, based on evidence of effectiveness and sensitive to legitimate fears and concerns, it offers the opportunity to win a greater level of public and political support for a programme of reform. Such a cautious, measured approach will also help placate critics, who fear that moves towards regulation are a ‘gamble’, un-evidenced or in some way ‘reckless’. A useful precedent for this is provided by some of the more contentious harm reduction policy developments of the past two decades, such as needle exchanges, supervised injecting venues, or opiate prescribing. Due to the highly charged political environment around drugs issues, such interventions have been subject to unprecedented regulation and scrutiny. Particular attention has been given to their effectiveness in reducing health harms, and to high profle concerns that they can somehow encourage use. Responses to such scrutiny have demonstrated 68 4 5 6 Making a regulated system happen Regulated drug markets in practice Appendices how effective policy interventions can be developed, public concerns can be dealt with sensitively, sensationalist media coverage responded to intelligently, and political opposition ameliorated. The increments along which phased change can be implemented are essentially in line with the range of regulatory tools described in chapters two and three. There is the potential to move from greater to lesser levels of regulation, controlling the levels of availability either through deployment of the different regulatory controls over suppliers, purchasers and products, or through their deployment at varying inten- sities. Where possible the longer term aim would be to encourage and move from legal/administrative controls towards social controls. Different countries will necessarily take different approaches, and see their policy and legal infrastructure develop along different routes. There will, for example, be very different challenges faced by primarily producer, transit or consumer countries, states with different levels of economic resources, political stability and public health and enforce- ment infrastructure, and states that are geographically isolated, compared to those with large borders with highly populated regions. Cannabis is likely to be the frst drug to have regulatory models more seriously explored. At the other end of the spectrum, around problematic dependent use of opiates and stimulants, we are likely to see medicalised maintenance 29 R. Newcombe, ‘Attitudes to drug policy and drug laws; a review of the international evidence’, Transform Drug Policy Foundation, 2004. These models will be based on already established, functional and effective interventions in numerous countries. These two emerging trends are already defning an ongoing pragmatic reform process —addressing the areas of most pressing practical necessity where prohibition’s effects are the most egregious, in population terms (cannabis) and overall harm creation (chaotic use/dependence). Within broad groupings of similar types of drugs—stimulants, depres- sants or hallucinogens (see: chapter 5)—we might reasonably expect regulated legal availability pilots to begin by focussing on the drugs least likely to be associated with personal or social harms and costs (see: 4. Similarly, less potent preparations of drugs, for use through lower risk methods of administration, could be made available in the frst instance. First, such rankings should inform policy makers, so that they can develop effective, targeted and proportionate policy responses to a range of different drug harms, which can thereby be managed and minimised. This is an essential element of developing effective regula- tory frameworks and inevitably requires a degree of population based generalisation. The second is to facilitate the education of individuals about drug risks and harms, so enabling them to make informed and responsible decisions about their health and wellbeing. Getting to grips with these questions requires that two important 70 4 5 6 Making a regulated system happen Regulated drug markets in practice Appendices distinctions are made. First of all, primary health harms to individual users should be distinguished from the secondary social harms to third parties that follow from that use. Second, harms related to drug use per se (both primary and secondary) should be distinguished from harms created or exacerbated by policy environments. The prevailing analysis that informs most current policy makes the frst distinction (between health and social harms) reasonably well, but largely fails to make the second distinction (between drug harms and policy harms). It confuses and confates the two, often misattributing prohibition or illicit market harms to drugs, or by default drug users, and feeding the self-justifying 30 feedback loop that has helped immunise prohibition from scrutiny. Some efforts to untangle drug use harms from drug policy harms have been made, although this is an area that warrants more detailed consid- eration and analysis. Correspondingly, the Transform report then makes a distinc- tion between the aims of the drug policy reform movement—to reduce or eliminate the harms specifcally created or exacerbated by prohibi- tion and illicit markets—and the more conventional aims of an effective drug policy—to reduce or eliminate the range of direct and indirect harms associated with drug use and misuse. A more comprehensive ‘taxonomy of drug-related harms’ has been 32 constructed by MacCoun and Reuter who break down forty six iden- tifed drug-related harms into four general categories: ‘health’, ‘social and economic functioning’, ‘safety and public order’, and ‘criminal justice’.
