Health and disease in human populations - Essay Example This essay outlines the hazards of agriculture on health with regard to diseases, illnesses, and work hazards; and will outline the benefits of farm production by taking a look at food security, physical and mental health, and social environments. According to Schenker (661-664), farming involves contact to a variety of respiratory toxins exposing farmers to various respiratory conditions. This includes contact to organic dusts through grain handling and enclosed animal feeding ways. For example, farmers that keep a large number animals can spend long hours in confined facilities exposing them to organic dust. Grain dirt is also inorganic dust and grains like sorghum appear to be the most associated with respiratory symptoms. Farmers risk exposed to bacterial, microbial, fungal organisms and toxic gases. Inorganic dirt is mainly soil component and has a high level of silica. This risk is associated mainly with farmers in arid regions. Chemical poisoning is another risk attached to farming practices. When not properly used can lead to death through poisoning. Price of medical attention, reduced productivity can be high. In emergent countries, wellbeing risks related to farming chemical products are having high chances of occur rence. Farmers in developing countries lack the knowledge on proper use of farm chemicals and regulatory systems of chemicals. Chemicals used in agriculture cause metal poisoning to natural sources of water. This can create immense health risks for populations that live in those areas. Agriculture practices provide reproduction places for disease and promote parasite longevity; cause loss of essential marauder species that control parasites increasing man-vector contact (Agricultural Development and Vector-Borne Diseases, 16). This includes parasites like mosquitoes. Irrigation schemes, crops grown, chemical inputs can all lead to the promotion of breeding of vectors that cause disease. Facilities

A clinical incident - Essay Example Mr. Halliday who had just undergone surgery for gastric carcinoma under general anaesthesia had respiratory distress during my posting in the post operative room. The anaesthetist advised tracheostomy. Immediately my senior whom I had assisted twice already in the procedure and observed it being done by her many times, posted me to the duty of assisting the anaesthetist to do it.

It was my first participation in a tracheostomy. The senior boosted my confidence and told me she would be around if assistance was needed. First I ensured the availability of the emergency tracheostomy kit. I had to speak to the patient and his family of wife and son about the procedure and its outcome. The patient himself was a little hazy from the anaesthesia of surgery. The wife and son were easily convinced but they wanted to know whether it is just for now or long term. Informing them that it has been intended for a short duration now and is being done for controlling the secretions, I felt pleased that things had started off smoothly. Checking the list that is used for the packing of instruments and other equipment for the emergency tracheostomy during preparation for autoclaving, I felt everything needed had been ready. The outer tube, the snugly fitting inner tube, the flange which lies against the patient’s chest and the 15mm termination which fits all ventilators and respiratory equipment were the main components necessary (Tracheostomy care working group, 2000). The optional parts were the cuff which helps fix the tube in position, the air inlet valve which prevents the escape of air, the air inlet line which would allow air to move from the air inlet valve to the cuff and the pilot cuff which is an indicator of the amount of air in the cuff (Tracheostomy care working group,
