Acute Intracranial Problems Intracranial pressure = closed system Cerebrospinal fluid 10% Intravascular fluid 12% Brain tissue 78% Monro-Kellie doctrine states that they must remain in relative constant volume to mntn homeostasis (normal pressure is 5-15, anything greater than 20 is worrisome) Hydrocephalus – peds have open fontanels and suture lines that are not bonded together, which creates an open system don’t see the typical s/s bc of the expansion that can happen Herniation – happens bc adults have closed system and there is nowhere for the pressure to go but down the brain stem complete devastation and grave danger Increased ICP – tumors, edema, trauma CM: headache, vomiting, seizures o LOC- any alteration of mental status, can be quick o Cushing’s triad- ↑ systolic BP (widening of pulse pressure), bradycardia, irregular RR Medical ER d/t brainstem compression and impending death o Ocular signs- pupils may be dilated, fixed, sluggish, pinpoint, unequal o Posturing changes- decorticate vs decerebrate Diagnostics: o CT/MRI of brain- used to discern the many conditions that can cause increased ICP and assess the effect of trmt o MRA of brain o EEGs Assessment: o

activation – 15mins o door to CT – 25mins o door to EKG, labs, and chest Xray – 45mins o door to CT results – 45mins o door to TPA – 60mins Transient Ischemic Attack – “mini stroke”, usually resolve w/in 1hr but may have effects that last for up to 24hrs May cause any of the symptoms of an ischemic stroke and may be severe or mild Puts people at risk for more TIAs and strokes in the future Ischemic Stroke – occurs when a blood clot blocks an artery, cutting off the flow of oxygen-rich blood to part of the brain Embolic- fewer warning signs, usually severe and sudden o Non-cardiac- pulmonary embolism and DVT o Cardiac- A-fib and patent foramen ovale Thrombotic- occlusion in the cerebral blood supply, more common, about 60%, occurs in association w/plaques and the narrowing of

the tip of the penis rather than at the tip Hydrocele – a fluid filled sac partially surrounding the testis CM: swelling on the side of the scrotum, may cause discomfort Trmt: can be surgically corrected Varicocele – dilated and twisted veins of the testis, sort of “hemorrhoids” of the scrotum CM: swelling on the side of the scrotum which may look and feel like a “bag of worms” o Can also cause reduced sperm count and male sterility d/t sluggish blood flow elevating testicular temp Trmt: may be surgically corrected if causing discomfort Cryptorchidism – literally “hidden testicle” or undescended testicle A condition of lack of descent of one or both testes into scrotum Trmt: surgery o If not correct can lead to sterility and ↑ risk of testicular cancer Assessment of prostate –

relive obstruction of the urinary tract Post op care and NI: o Pt will have catheter w/continuous bladder irrigation – need to mntn catheter patency o Pain control o Adequate bladder irrigation for 24hrs o Accurate I/Os o Discuss sexual concerns- erectile dysfunction, may take >1yr to be as active as preop o Encourage perineal exercise to ↑ sphincter tone o Meds- stool softeners, antibiotics PSA (prostate specific antigen) = a marker specific protein for prostate cell secretions which can be detected in a simple blood sample, a rising PSA may be an early sign of prostate cancer – although there may be other causes including false + tests Prostate Cancer - #1 cancer among men, #2 cancer killer in men behind lung cancer Prognosis: varies widely and depends on many factors like age, health of the client, stage of the cancer at diagnosis, cancer responsiveness to trmt CM: asymptomatic mostly which is why the PSA test is so important along w/yearly DRE and a prostate risk calculator, symptoms are more likely if cancer is advanced like… 15 o Difficulty w/an erection o Straining to pass urine o Leaking/bloody urine o Bone pain that radiates down the hips/legs may indicate metastasis Trmt: watchful waiting o Surgery to remove prostate o Radiation/cyro/hormonal/chemo/immune/other targeted therapies o Research techniques include high-intensity focused US (HIFU) o Meds- bisphosphonates, denosumab, radiopharmaceuticals (radioactive substances used as drugs) Priapism – a persistent, often painful, erection lasting more than 4hrs, not associated w/sexual activity Trmt: medical ER bc a prolonged erection can scar the penis and result in a long-term complication of erectile dysfunction if not treated o Goal of trmt is to relieve the erection and preserve normal penile function o In most cases, draining the blood using a needle placed in the side of the penis Causes: o Alcohol or drug abuse (esp. cocaine) o Certain meds, including some antidepressants and BP meds o Spinal cord problems o Injury to the genitals o Anesthesia o Penile injection therapy (also a trmt for erectile dysfunction) o Blood diseases including leukemia and sickle cell anemia Erectile

Phimosis – a condition in which the foreskin of the penis is so tight that it cannot be pulled back/retracted to reveal the head of the penis (children and adults) Etiology: seen most often children and may be present at birth, can also be caused by an infection or by scar tissue that formed because of injury or chronic inflammation o Another cause is balanitis (infection of the head of the penis) which leads to scarring and tightness of the foreskin o Sometimes nursing staff can be the cause of the problem w/o proper foley cath care and mntn 17 Trmt: circumcision is often used to treat it o Preputioplasty involves separating the foreskin from the glans which preserves the foreskin and is less traumatic than circumcision Complications: immediate medical attn is necessary if the condition makes urination difficult/impossible Penile Cancer – rare form of cancer that occurs when abnormal cells in the penis divide and grow uncontrolled, certain benign tumors may progress and become cancer CM: o Growths and sores on the penis o Abnormal discharge beneath the foreskin o Bleeding Trmt: sx to remove the cancer is the most common trmt for penile cancer, doctor may take out the
