If the respiratory rate drops below 8 breaths per m inute assisted or artificial ventilation should be used safe 800 mg viagra vigour impotence quotes. Concussion and M inor Head injuries Concussion Concussion of the brain can occur w hen a heavy blow is applied to purchase viagra vigour 800mg with amex impotence of organic origin icd 9 the skull purchase 800 mg viagra vigour with amex erectile dysfunction treatment melbourne. It occurs because the brain is fairly soft and its function can be subject to w idespread disturbance w hen shock w aves pass through its substance. Suspect this condition if the casualty loses consciousness for only a few m inutes. It is characterised by a loss of m em ory for events before or after the injury, headache and som etim es nausea and vom iting. Headache m ay be troublesom e and paracetam ol or codeine phosphate m ay be required. The casualty should be w arned to report im m ediately if he notices increasing headaches or drow siness or if he vom its. Because the head is w ell supplied w ith blood, a collection of blood Haem otom a (haem atom a) w ill form in the tissues under the scalp. It m ay Skull be sharply defined, hard and tense, or it m ay be a fairly diffuse soggy sw elling (Figure 4. If the soggy area is large B it m ay indicate an underlying fracture so the patient should be closely m onitored. These are com m on because there is little tissue betw een the skull and the scalp. The w ound w ill bleed freely and often out of proportion to the size of the w ound. Surrounding tissues m ay be sw ollen and soggy w ith the blood that has leaked into them. Pain Relief in Head Injuries Paracetam ol should be used in m inor injuries for relief of headaches. M orphine should not be given unless the head injury is trivial and the casualty has serious and painful m ajor injuries elsew here. Sciera/w hite of the eye Conjunctiva Upper eyelid Extraocular m uscles Cornea Iris Lens Low er eyelashes Optic nerve Retina Choroid Figure 4. They are guarded by the eyelids (upper and low er) w hich have the faculty of blinking and closure. The w hite part of the eye is the sclera and the clear transparent central part is the cornea. Behind the pupil, w hich appears black in colour, is the lens w hich is not norm ally visible. The retina is the inner lining of the eyeball and it provides the sight receptors. The conjunctiva is the outer lining, a thin m em brane w hich covers both the inner surfaces of the upper and low er eyelids, and the visible part of the eyeball except for the cornea (Figure 4. Exam ination the first stage in treating an eye injury is to record a full account of the injury, w hat happened and the details of the sym ptom s. It helps if the casualty is lying dow n, w ith head supported and held slightly back, during the exam ination. Basic requirem ents are: s Good illum ination (overhead light, lam p, or hand held torch or strong day light); s M agnifying glass; s Soft paper tissues; s M oist cotton w ool sw abs or m oist cotton buds; s Fluorescein drops (stain); s Anaesthetic eye drops; s Basic antibiotic eye ointm ent. First record the general appearance of the tissues around the eye(s), looking for sw elling, bruising or obvious abnorm ality; and then exam ine the affected eye(s) starting w ith the sclera, the conjunctiva, w hich covers both the sclera and the backs of the eyelids, and the cornea. Com paring one eye w ith the other is helpful and a diagram is the best m ethod of recording the findings. The inside of the low er lid can be inspected by gently pulling dow n the low er lid w ith the eyes looking upw ards. The upper lid m ust be rolled back (everted) before the underlying conjunctiva can be inspected. Both require the casualty to M ethod I keep looking dow n tow ards the feet w hile the technique is being com pleted. To evert the upper lid, ask the casualty to rem ain looking dow nw ards then place the index finger of one hand across the upper lid w hile grasping the eyelashes firm ly but gently betw een the index finger and thum b of the other hand. Pull gently dow nw ards on the eyelashes and then w ith a dow nw ard pressure of the index finger fold the eyelid back over it.

This handbook is dedicated to the late Kate O’Hanlon, Sister in Charge, Royal Victoria Hospital, Belfast, for her dedication to serving the people of Northern Ireland and her inspirational leadership of emergency nurses. Unlike other felds of care, pre-registration education prepares clinical staf poorly for emergency care, for the sheer volume and nature of work, for the complexity and often simplicity of the patients’ problems, or for the inter-dependency of the professionals working within it. There is little that can prepare us, other than immersion in the work and a personal com mitment to continuing development. Every clinical shift or project provides an opportunity to understand better a diagnosis or care process. A simple audit of pain management can enable staf to challenge the quality of care delivered and/or to enhance patient-centred treatment models. They are the textbook generalists—experts in the frontline management of any presentation, but also skilled in accessing spe cialist help. They assess patients, their families, and the situation around them constantly, in order to make sense of their patients’ needs. They must use this skill to ask the right questions, in order to compare and prioritize patients efectively, so that everyone receives treatment which is safe and efective. Increasingly, they practise autonomously across the full spectrum of the patient workload, expanding their scope and impact within the emer gency care feld. In addition, they must respond quickly to public health emergencies, whilst still being committed to developing their services for the chronic shift in population health needs. Access to applicable and realistic information is essential for care, as patient treatment must be evidence-based for staf to make efective deci sions. Information has never been more accessible than it is today, yet there is often a lack of concise and precise data that enable our practitioners to make timely decisions and to learn as they practise. It contextualizes care in that setting, and it provides a concise overview of the vast range of presentations and skills needed to practise safely, whilst providing plenty of opportunities for further learning. Wherever you are in the world, you are providing emergency care, and you should keep this handbook within reach. We wanted to write a comprehensive, easily accessible text that provided valuable infor mation for every question or query that may arise in the course of a shift. The vast array of clinical presentations in emergency care can be daunting for those new to the specialty. Prioritizing care in a fast-paced environment is a unique skill that has to be underpinned by a sound knowledge base. This handbook covers the whole range of adult and paediatric emergency presentations. Each chapter covers a physiological system and starts with a review of anatomy and physiology (where appropriate). The chapter’s format allows the clinician to quickly review the associated presentations, priorities, and red fags. The fnal skills chapter details the multitude of clin ical skills and procedures encountered in emergency care. Now available in digital format (smartphone application), it can support clinical practice in any setting. The provision of emergency care has changed signifcantly since the frst edition, and the new edition refects this. There are two new chapters, on major trauma and elderly care, which cover all the essential elements of these priority areas. Several chapters have been written by experts in their respective felds, and both editions have been enhanced by their contribution. We hope that this handbook, in either its written or digital form, provides you with immediate access to the knowledge and skills you require.
