Chapter 71 In patients with stab wounds treatment 0f gout generic phenytoin 100 mg without prescription, sinography may be performed to detect peritoneal penetration medicine woman generic phenytoin 100mg mastercard. With this procedure, a pursestring suture is placed around the wound, and a small catheter is introduced through the wound. A contrast agent is then introduced through the catheter, and x-rays are taken to identify any peritoneal penetration. To decompress the bladder and monitor urine output, an indwelling catheter is inserted after a rectal examination (not before). In the male patient, a high-riding prostate gland (abnormal position) discovered during a rectal examination indicates a potential urethral injury. Assessment and Diagnostic Findings the patient is observed for the following: · Hypovolemic shock resulting from extravasation of blood · and plasma into injured tissues after compression has been released Paralysis of a body part Erythema and blistering of skin Damaged body part (usually an extremity) appearing swollen, tense, and hard Renal dysfunction (prolonged hypotension causes kidney damage and acute renal insufficiency; myoglobinuria secondary to muscle damage can cause acute renal failure)! Management In conjunction with maintaining the airway, breathing, and circulation, the patient is observed for acute renal insufficiency. Severe muscular damage causes a significant release of myoglobin, which can result in acute tubular necrosis. Additionally, major soft tissue injuries are splinted early to control bleeding and pain. Again, the serum lactic acid concentration is monitored; a decrease to less than 2. To restore neurovascular function, the physician may perform a fasciotomy (surgical incision to the level of the fascia). Medications for pain and anxiety are then administered as prescribed, and the patient is quickly transported to the operating suite for wound dйbridement and fracture repair. Then, a hyperbaric chamber (if one is available) can be used for hyperoxygenation of the crushed tissue, if indicated. A patent airway is maintained, and attempts to stabilize the respiratory, circulatory, and nervous systems are made. Bleeding is controlled by application of direct pressure to any external bleeding wounds and by occlusion of any chest wounds. Circulating blood volume is maintained with intravenous fluid replacement, including blood component therapy. The patient is monitored for signs and symptoms of shock after an initial response to transfusion therapy, because these are often the first signs of internal hemorrhage. A backboard may be used for transporting the patient to the x-ray department, to the operating room, or to the intensive care unit. Cervical spine immobilization is maintained until cervical x-rays have been obtained and cervical spine injury ruled out. Knowing the mechanism of injury (eg, penetrating force from a gunshot or knife, blunt force from a blow), is essential to determining the type of management needed. If abdominal viscera protrude, the area is covered with sterile, moist saline dressings to keep the viscera from drying. Typically, oral fluids are withheld in anticipation of surgery, and the stomach contents are aspirated with a nasogastric tube to reduce the risk of aspiration. Nasogastric aspiration also decompresses the stomach in preparation for diagnostic procedures. Trauma predisposes the patient to infection by disruption of mechanical barriers, exposure to exogenous bacteria from the environment at the time of injury, and diagnostic and therapeutic procedures (nosocomial infection). If there is continuing evidence of shock, blood loss, free air under the diaphragm, evisceration, hematuria, or suspected or known abdominal injury, the patient is rapidly transported to surgery. Immediately after injury, the body is hypermetabolic, hypercoagulable, and severely stressed. Mortality in patients with multiple injuries is related to the severity of the injuries and the number of systems and organs involved. Assessment and Diagnostic Findings Gross evidence of trauma may be slight or absent. The injury regarded as the least significant in appearance may be the most lethal. For example, the pelvis fracture not identified until x-ray may be the injury from which the patient is exsanguinating into the pelvic cavity.

The juxtamedullary nephrons are distinguished by their long loops of Henle and the vasa recta medicine 4 you pharma pvt ltd 100 mg phenytoin sale, long capillary loops that dip into the medulla of the kidney symptoms diagnosis discount 100mg phenytoin visa. The glomerulus is composed of three filtering layers: the capillary endothelium, the basement membrane, and the epithelium. The glomerular membrane normally allows filtration of fluid and small molecules yet limits passage of larger molecules, such as blood cells and albumin. Kidney function begins to decrease at a rate of approximately 1% each year beginning at approximately age 30. Ureters, Bladder, and Urethra Urine, which is formed within the nephrons, flows into the ureter, a long fibromuscular tube that connects each kidney to the bladder. There are three narrowed areas of each ureter: the ureteropelvic junction, the ureteral segment near the sacroiliac junction, and the ureterovesical junction. The angling of the ureterovesical junction is the primary means of providing antegrade, or downward, movement of urine, also referred to as efflux of urine. Each kidney has about 1 million nephrons, which take two forms: cortical and juxtamedullary. Cortical nephrons are located in the cortex of the kidney; juxtamedullary nephrons are adjacent to the medulla. During voiding (micturition), increased intravesical pressure keeps the ureterovesical junction closed and keeps urine within the ureters. As soon as micturition is completed, intravesical pressure returns to its normal low baseline value, allowing efflux of urine to resume. Therefore, the only time that the bladder is completely empty is in the last seconds of micturition before efflux of urine resumes. The three areas of narrowing within the ureters have a propensity toward obstruction because of renal calculi (kidney stones) or stricture. Obstruction of the ureteropelvic junction is the most serious because of its close proximity to the kidney and the risk of associated kidney dysfunction. The lining of the ureters is made up of transitional cell epithelium called urothelium. The movement of urine from the renal pelves through the ureters into the bladder is facilitated by peristaltic waves (occurring about one to five times per minute) from contraction of the smooth muscle in the ureter wall (Walsh, Retik, Vaughan & Wein, 1998). In adolescence and through adulthood, the bladder assumes its position in the true pelvis. The bladder is characterized by its central, hollow area called the vesicle, which has two inlets (the ureters) and one outlet (the urethrovesical junction), which is surrounded by the bladder neck. Immediately beneath the adventitia is a smooth muscle layer known as the detrusor. Beneath the detrusor is a smooth muscle tunic known as the lamina propria, which serves as an interface between the detrusor and the innermost layer, the urothelium. The urothelium layer is specialized, transitional cell epithelium, containing a membrane that is impermeable to water. The bladder neck contains bundles of involuntary smooth muscle that form a portion of the urethral sphincter known as the internal sphincter. The portion of the sphincteric mechanism that is under voluntary control is the external urinary sphincter at the anterior urethra, the segment most distal from the bladder (Walsh et al. Chapter 43 the urethra arises from the base of the bladder: In the male, it passes through the penis; in the female, it opens just anterior to the vagina. In the male, the prostate gland, which lies just below the bladder neck, surrounds the urethra posteriorly and laterally. These functions include urine formation; excretion of waste products; regulation of electrolyte, acid, and water excretion; and autoregulation of blood pressure. Urine formation Excretion of waste products Regulation of electrolytes Regulation of acid­base balance Control of water balance Control of blood pressure Renal clearance Regulation of red blood cell production Synthesis of vitamin D to active form Secretion of prostaglandins Urine Formation Urine is formed in the nephrons through a complex three-step process: glomerular filtration, tubular reabsorption, and tubular secretion. Figure 43-3 illustrates the three processes of urine formation and typical values of water and electrolytes associated with each process. The various substances normally filtered by the glomerulus, reabsorbed by the tubules, and excreted in the urine include sodium, chloride, bicarbonate, potassium, glucose, urea, creatinine, and uric acid. Within the tubule, some of these substances are selectively reabsorbed into the blood. Others are secreted from the blood into the filtrate as it travels down the tubule.

Although recommendations vary medicine 2016 buy phenytoin 100mg visa, most women are advised to wait 2 years before becoming pregnant after completing treatment for breast cancer medications ranitidine buy 100mg phenytoin with visa. Most retrospective studies indicate that pregnancy after treatment for breast cancer does not appear to increase the risk of the disease recurring (Gemignani & Petrek, 1999); however, prospective studies are needed to confirm this. Counseling, providing accurate information, and active listening and caring are important nursing interventions when patients are involved in making difficult personal decisions about treatment options, childbearing, or termination of pregnancy. Pertinent questions include the following: · How is the patient responding to the diagnosis? Planning and Goals the major goals for the patient may include increased knowledge about the disease and its treatment; reduction of preoperative and postoperative fears, anxiety, and emotional stress; improvement of decision-making ability; pain management; maintenance of skin integrity; improved self-concept; improved sexual function; and the absence of complications. In view of the usually overwhelming emotional reactions to the diagnosis, the patient must be given time to absorb the significance of the diagnosis and any information that will help her to evaluate treatment options. The nurse caring for the woman who has just received a diagnosis of breast cancer needs to be knowledgeable about current treatment options and able to discuss them with the patient. The nurse should be aware of the information that has been given to the patient by the physician. Information about the surgery, the location and extent of the tumor, and postoperative treatments involving radiation therapy and chemotherapy are details that the patient needs to enable her to make informed decisions. As appropriate, the nurse discusses with the patient medications, the extent of treatment, management of side effects, possible reactions after treatment, frequency and duration of treatment, and treatment goals. Methods to compensate for physical changes related to mastectomy (eg, prostheses and plastic surgery) are also discussed and planned. Patients who have lost close relatives to breast cancer (or any cancer) may have difficulty coping with the possible diagnosis of breast cancer because memories of loss and death can emerge during their own crisis. If she will undergo a mastectomy, information about various resources and options is provided. Such services include prostheses, reconstructive surgery, and groups such as Reach to Recovery. The nurse provides anticipatory teaching and counseling at each stage of the process and identifies the sensations that can be expected during additional diagnostic procedures. The patient is introduced to other members of the oncology team (eg, radiation oncologist, medical oncologist, oncology nurse, and social worker) and is acquainted with the role of each in her care. After the treatment plan has been established, the nurse needs to promote preoperative physical, psychological, social, and nutritional well-being. Some women find it helpful and reassuring to talk to a breast cancer survivor, someone who has completed treatment and has been trained as a volunteer to talk with newly diagnosed patients. Careful guidance and supportive counseling are the interventions the nurse can use to help such a patient. Also, encouraging the patient to take one step of the treatment process at a time can be helpful. The advanced practice nurse or oncology social worker can be helpful for patients and family members in discussing some of the personal issues that may arise in relation to treatment. Some patients may need a mental health consultation before surgery to assist them in coping with the diagnosis and impending treatment. Such patients may have had a history of psychiatric problems or demonstrate behavior that leads the surgeon or nurse to initiate a referral to the psychiatrist, psychologist, or psychiatric clinical nurse specialist. Patients should be encouraged to take analgesic agents (opioid or nonopioid analgesic medications such as acetaminophen) before exercises or at bedtime and also to take a warm shower twice daily (usually allowed on the second postoperative day) to alleviate the discomfort that comes from referred muscle pain. A particular concern is preventing fluid from accumulating under the chest wall incision or in the axilla by maintaining the patency of the surgical drains. The dressings and drains should be inspected for bleeding and the extent of drainage monitored regularly. If a hematoma develops, it usually occurs within the first 12 hours after surgery; thus, monitoring the incision is important. A hematoma could cause necrosis of the surgical flaps, although this complication is rare in breast surgery patients. If either of these complications occurs, the surgeon should be notified, and the patient should have an Ace wrap placed around the incision and an ice pack applied. Initially, the fluid in the surgical drain appears bloody, but it gradually changes to a serosanguinous and then a serous fluid during the next several days.
