Diagnosis and acute management of the subarachnoid represents a great challenge to the neurologists, neurosurgeons, interventions radiologists and intensivists. In this case study we analyze the factors that are involved in the subarachnoid hemorrhage and their relation with the delayed ischemia that is occur because of the cerebral vasospasm. In this study we also evaluate the role of the practitioners regarding to this disease. In most of the population the incidence of subarachnoid hemorrhage is 6-7 individuals per 100, 000 persons in a year. Incidence of subarachnoid hemorrhage increases with the age. Their risk factors are smoking, constant or excessive alcohol intake and hypertension. In the patients who have positive family history for subarachnoid hemorrhage, the average age at which the disease strikes to them is younger age than in patients with the sporadic subarachnoid hemorrhage. So, genetic factors also play significant role in this disease. Factors that are involved in the rupture of the arachnoid membrane are very complex; it happens because of the sudden increase in trans mural arterial pressure, activities such as exercise, straining and intercourse are reported as 20% necessary factor in the prevalence subarachnoid hemorrhage (Zentner, et al., 1996). The main characteristic symptom of subarachnoid hemorrhage is the head ache. This head ache is different from the normal head ache that usually occurred in individuals in their daily routine life due to extensive hard work. Head ache usually last 1- 2 weeks and sometime longer and of very high intensity. Vomiting is also the characteristic of this disease but it is not distinctive one because it also occurred in the patients of non-hemorrhagic. Focal neurological deficits occur when an aneurysm compresses a cranial nerve or bleeds into the brain parenchyma or from focal ischemia due to acute vasoconstriction immediately after aneurysmal rupture. Sometimes, therefore, the clinical manifestations of a ruptured aneurysm are indistinguishable from a stroke syndrome from cerebral infarction. Complete or part third-nerve palsy is a well-recognized sign after rupture of aneurysms, mostly of the internal carotid artery at the origin of the posterior communicating artery (Wartenberg, et al., 2006). Systematic feature which are associated with the subarachnoid hemorrhage are sever hypertension, hypoxemia and electrocardiographic changes which can mimic the myocardial infarction and lead to erroneous examinations and treatments. The first investigation if the subarachnoid hemorrhage is suspected is CT scan. Their detection depends on the amount of blood that leaked into the subarachnoid space. The indication of surgery in patients of subarachnoid hemorrhage can be done if the overall medical condition of the patient is out of control, like aneurysm size and location, accessibility of the aneurysm for surgical repair, and presence or absence of thrombus, are also important (Wartenberg, et al., 2006). Cerebral vasospasm is the intensive and prolonged vasoconstriction of the large conducting arteries in the subarachnoid space that is initially surrounded by the clot. The further narrowing of the vessels develop gradually over the first few days after the aneurysmal ruptur ...Download file to see next pagesRead More

Nursing care and treatment of cerebral vasospasm following subarachnoid haemorrhage

...of devastating complications, like vasospasm, hydrocephalus and rebleeding. Of these, currently, vasospasm is the main cause of morbidity and mortality (Becske, and Jallo, 2010). Cerebral vasospasm Vasospasm may be defined as "a delayed narrowing of the large arteries at the base of the brain after SAH, with evidence of diminished perfusion in the territory distal to the affected arteries" (Nazh and Mayer, 2003). Following the initial episode of subarachnoid hemorrhage, arteries surrounding the site of bleed go into spasm, leading to ischemia and infarction of the regions of the brain supplied by those arteries. The spasm can occur in...

Cerebral Lateralization: Cerebral Asymmetry Practical

...Cerebral lateralization: Cerebral Asymmetry Practical. This experiment was set to investigate cerebral asymmetry among thirty participants. The aim of this experiment was to find out the accuracy speed of phonological processing in the left and right hemispheres. The hypothesis for this study was “verbal processing as measured by the rhyme/non-rhyme task is faster and more accurate in the left hemisphere than the right hemisphere of the brain”. Several pairs of words with a destructor were given to the participants. They were then asked to show out which words either rhymed or did not rhyme. The participants of the study were directed to press a key (A) if the words shown could not rhyme,...

Despite of all the benefits and positive outcomes of the psychological conditioning it did not seem to be beneficial in improving her cognitive thinking, writing and calculation capacities. These are few areas which I found to have shown no impact of operant conditioning.

Postpartum Haemorrhage, Hypovolaemic Shock, Post-Traumatic Stress Disorder enable them to cope with any excessive blood loss (Hofmeyr and Mohlala 2001, p. 646). After childbirth there is the risk of haemorrhage that can come from a variety of locations. Immediate haemorrhage is more commonly associated with mortality and can come from different factors surrounding the birth. In as much as 90% of the cases of immediate post-birth haemorrhage the cause is uterine atony which has a number of causes, including incomplete delivery of the placenta. When there are cotyledons, or retained placental fragments, there is both the risk of immediate haemorrhage and of delayed haemorrhage (Varney, Kriebs,...

Early Post Partum Haemorrhage

...EARLY POST-PARTUM HAEMORRHAGE Vermice Newton, a 30 year-old patient, is well on her 39th week of pregnancy but still shows nosigns of labor. The whole term of her pregnancy went well except for the edema that went from bad to worse in the last two weeks. Feeling restless, she then requested that she be induced to labor. Several hours later, she was back on her room with her baby sleeping quietly. Upon checking on her, the nurse finds her quite pale. When she got her vital signs, her pulse was at 98 beats per minute and her blood pressure at 90/50. When her sheets were checked, blood was pooling on her back and her deep slumber prevented her from knowing it. She was having one of the most serious...

Cerebral Palsy

...Cerebral Palsy According to the Centers for Disease Control and Prevention (CDC) , the average prevalence of cerebral palsy is 3.3 per 000 8-year old children or 1 in 303 children, in three specific states, which is slightly decreased as compared to the 3.6 per 1,000 or 1 in 278 children the previous year. Although statistics may show a positive drop, continuous efforts for awareness and prevention are conducted to lessen the number of children that would suffer the chronic, lifelong, incurable condition. The Disorder Cerebral Palsy is defined by CDC (2010) as “a group of disorders that affect a person’s ability to move and keep their balance and posture as a result of an injury to parts of the brain, or as a result of a problem... with...

Cerebral Palsy

.... This could be caused by infections to the mother, such as rubella, premature birth, low blood pressure, or illegal drug use when pregnant (Shepherd 22). Another cause of CP in infants is abnormal brain development. This leads to alteration of brain and body muscle communication. Any brain development abnormality could lead to CP with the foetus being especially vulnerable to this. Gene mutations in those genes that are important in the development of the brain also lead to CP, as do some infections like herpes and toxoplasmosis and trauma to the infants head (Shepherd 24). Finally, intracranial haemorrhage in infants before and after birth due to a stroke could cause CP. Brain bleeds can cause the...
