Ante/pre operative infections: These infections happen before a surgical procedure quality danazol 50 mg. Example: - Accidents - Appendicitis - Boils - Carbuncle - Pyomyositis… Operative infections: These are types of surgical infections that happen during a surgical procedure discount danazol 50 mg with mastercard. It can occur either due to contamination of the site or poor tissue handling technique. These include: - An infectious agent - A susceptible host - Favorable external factors or local condition with closed, less or non-per fused space. An infection becomes overt only when the equilibrium between the bacterial and host factors becomes disturbed. The common organisms in decreasing order are:- 1- Aerobic bacteria - Staphylococcus aureus - Streptococci - Klebsiella - E. Host Susceptibility: Reduced immune host defense predisposes to surgical infections. Local and external factors: Closed spaces, usually with poor vascularization, are areas susceptible to infection. Favorable situations under such condition contributing to infection include:- - Poor perfusion of blood and oxygen - Presence of dead tissue 63 - Presence of foreign bodies - Closure under tension etc. External factors like a break in the sterility technique also contribute to the development of surgical infection. Post-Operative Wound Infection This is contamination of a surgical wound during or after a surgical procedure. Source of infection: The source of contamination in more than 80% cases is the patient (endogenous). In about 20% of cases, the source is from the environment, operating staff or unsterile surgical equipment (exogenous). It contains necrotic tissue and suppuration from damage by the bacteria, and white blood cells. It is surrounded by area of inflamed tissue due to the body’s response to limit the infection. Clinical features: Patients with an abscess anywhere in the body may present with the following findings. It usually involves the extremities and identifiable portal of entry is detectable. Etiology: The most common etiologic organisms are - Beta hemolytic streptococci - Staphylococci - Clostridium perfringens Clinical Features: There is usually an identifiable portal of entry which can be a surgical wound, puncture site, skin ulcer or dermatitis. Clinical Pictures: - Series of small intra epithelial abscesses , multiple - Bullous lesions - Skin erosion and - Crust formation. Poor hygiene, immune suppressive diseases and irritation are known contributing factors. Clinical feature: - There is an intense local irritation of acute onset - Painful firm, reddish, round swelling initially, which later becomes fluctuant - Suppuration and central necrosis occurs later - The condition subsides and is self-limited to recur in multiple lesions (chronicity) Treatment: • It may subside spontaneously without suppuration (Blind boil) • Incision /Excision if complicated • Antibiotics Carbuncle Carbuncle is an infective gangrene of subcutaneous tissue which commonly occurs in patients with diabetes and other immune suppressive conditions. Clinical Feature: • Formed by multiple furuncles • Pain • Erythema • Induration • Progressive suppuration of thick pus • Tissue loss with shallow and deep ulcer surrounded by smaller areas of necrosis 67 Treatment: • Adequate systemic antibiotics in early stages • Aggressive debridement • Local wound care • Detect and treat predisposing factors like diabetes mellitus Pyomyositis Pyomyositis is an acute bacterial infection of skeletal muscles with accumulation of pus in the intra-muscular area. It usually occurs in the lower limbs and trunk spontaneously or following penetrating wounds, vascular insufficiency, trauma or injection. Poor nutrition, immune deficiency, hot climate and intense muscle activity are highly associated factors. Clinical Features: It usually has sub-acute onset and can present with • Localized muscle pain and swelling, late tenderness • Induration, erythema and heat • Muscle necrosis due to pressure • Fever and other systemic manifestations later after some days Treatment: • Immediate intravenous antibiotics before surgery • Surgical drainage of all abscess • Excision of all necrotic muscles • Supportive care Madura Foot This is a chronic granulomatous disease commonly affecting the foot with extensive granulation tissue formation and bone destruction. The disease is common in the tropics and occurs through a prick in barefoot walkers in 90% of cases. Etiology: The causative microorganisms for this infection are various fungi or actinomycetes found in road dust. Treatment: • Sulphonamides and Dapson (prolonged course) • Broad spectrum antibiotics for secondary infection • Amputation if severe and disfiguring infection Necrotizing fasciitis This is an acute invasive infection of the subcutaneous tissue and fascia characterized by vascular thrombosis, which leads to tissue necrosis. It is idiopathic in origin but minor wounds, ulcers and surgical wounds are believed to be initiating factors. The condition is described as "Meleney’s synergistic gangrene" if it occurs over the abdominal wall and “Fournier’s gangrene “if in the scrotum and perineal area. Bacteriology: Mixed pathogens of the following microorganisms are usually cultured. The following surgical procedures may be required: - Debridement and excision of all dead tissue - Multiple incisions for drainage - Repeated wound inspection - Skin graft may be needed later if extensive skin involved. It can practically be eliminated by tetanus vaccine immunization if properly initiated and maintained. Etiology: Clostridium tetani, a gram-positive rod found in soil and manure is the causative agent.
In patients with hyperinfection syndrome buy danazol 50 mg with mastercard, the standard dose is continued twice daily for 5-7 days trusted 100 mg danazol. Cutaneous Larva Migrans (Creeping Eruption) The standard dose is given twice daily for 2 days. Adverse Reactions: Adverse effects are generally mild and transient but can be severe; the most common are dizziness, anorexia, nausea, and vomiting. The most important axiom of toxicology is that “the dose makes the poison”, indicating that any chemical or drug can be toxic if the dose or exposure becomes high enough. Poisoning occurs by non-therapeutic substances such as household and environmental agens, and due to over-dosage of therapeutic substances. A difficult challenge to the health care provider is the identification of the toxicant and limited availability of antidotes. Thus, the health care provider in most cases, may be limited with symptomatic therapy. A toxic response can occur with in minutes or after a delay of hours, days, months or years. General measures in poisoning The treatment of a poisoned patient requires a rapid and genuine approach. There are three principles underlying the management of poisoning: • Life support • Drug identification • Drug detoxification 196 Drug overdose or poisoning by other chemicals can often manifest itself as an acute clinical emergency. The kinds of life-threatening emergencies include seizures, cardiac arrhythmias, circulatory shock and coma. Massive damage to liver, lungs or kidneys can also lead to death with in a relatively short period of time. Immediate supportive measures may take precedence over identification and detoxification of the offending agent. Therefore, maintenance of vital functions such as respiration, circulation, suppression of seizures, etc. Drug identification and the amount taken may have to be deduced frrm a combination of client history, clinical manifestations and laboratory findings. The first action for drug detoxification is to cease the administration of the offending agent until the crisis is under control. The effectiveness of the approaches employed for detoxification may depend on the route of administration of the poison. The general approaches employed to reduce systemic absorption of an ingested poison where the client still has an intact gag reflex is to administer an emetic (eg. Within clinical environment, more invasive procedures such as gastric lavage and haemodialysis can be performed. Antidotes are available against poisoning with the following substances and are able to reverse the toxic manifestations (see table 11. Describe poisoning management measures that hinder the absorption of the poison from the gut. A prescription is a written order by a registered physician, dentist or veterinarian to prepare and/or dispense pharmacological agents for patient. A drug that requires a prescription from a licenced prescriber to be dispended by a pharmacist is termed legend drug. In precompounded prescription, drugs prescribed are supplied by the pharmaceutical companies in ready prepared form by its nonproprietary or trade name. Constructin of a prescription: A ideal prescription should contain a) the name, qualification, registration number, full address, telephone number and working hours of the physician; b) the full name, sex, age and address of the patient; c) the diagnosis, the drug preparation, total amount, frequency of administration advises and signature of the prescriber. The name of the drug preparation begins with the symbol Rx means take thou derived from a Roman symbol for Jupiter. Prescription incompatibility: In competency or careless of the prescriber results incompatable prescription. It may lead to failure of desired therapeutic goal, may prove harmful or even death to the patient. Patient’s compliance: A matter of concern for prescriber with regard to prescription is patient’s noncompliance i. Noncompliance includes taking of inadequate doses, improper timing, preterm discontinuation of drug. Criteria for rational prescribing: Rationa prescribing should meet the certain criteria such as appropriate diagnosis, indication, drug, patient, dosage, duration, route of administration, information and monitoring. Irrational prescription: Over use of antibiotics, indiscriminate use of injections, excessive use of drugs, use of anabolic steroids for growth and use of tonics and multivitamins for malnutrition are some of irrational practices.
