Urinary lower

Cefotetan, a second-generation cephalosporin antibiotic (1 to 2 g rV or IM q. 12 hours), is indicated in the treatment of serious urinary, lower respiratory, gynecologic, skin, intraabdominal, and bone and joint infections caused by susceptible organisms. 

Rats exposed to 500 ppm of bromotrifluoroethylene died following a 4-h exposure. Since the monomer decomposes in air, the level of exposure to it was actually lower. The effects in rats of repeated exposure over a two-week period have been studied. At 50 ppm, the animals lost weight and renal damage was noted although the effect was reversible. Very mild testicular damage was seen at 50 but not 10 ppm. The amount of urinary duotide excreted suggested that extensive metaboHsm was occurring (34). 

Of the water-soluble vitamins, intakes of nicotinic acid [59-67-6] on the order of 10 to 30 times the recommended daily allowance (RE)A) have been shown to cause flushing, headache, nausea, and moderate lowering of semm cholesterol with concurrent increases in semm glucose. Toxic levels of foHc acid [59-30-3] are ca 20 mg/d in infants, and probably approach 400 mg/d in adults. The body seems able to tolerate very large intakes of ascorbic acid [50-81-7] (vitamin C) without iH effect, but levels in excess of 9 g/d have been reported to cause increases in urinary oxaHc acid excretion. Urinary and blood uric acid also rise as a result of high intakes of ascorbic acid, and these factors may increase the tendency for formation of kidney or bladder stones. AH other water-soluble vitamins possess an even wider margin of safety and present no practical problem (82). 

ACE inhibitors lower the elevated blood pressure in humans with a concomitant decrease in total peripheral resistance. Cardiac output is increased or unchanged heart rate is unchanged urinary sodium excretion is unchanged and potassium excretion is decreased. ACE inhibitors promote reduction of left ventricular hypertrophy.

Urinary pH. The solubility of phosphate salts increases at lower pH values, while pH scarcely affects the solubility of Ca(C204) over a pH range of 5.7 to 7.5. Bacteria that metabolize urea contribute to an alkaline medium, thus decreasing the solubility of phosphates. 

The fluoroquinolones are used in the treatment of infections caused by susceptible microorganisms. The fluoroquinolones are effective in the treatment of infections caused by gram-positive and gram-negative microorganisms. They are primarily used in the treatment of susceptible microorganisms in lower respiratory infections, infections of the skin, urinary tract infections, and sexually transmitted diseases. Ciprofloxacin, norfloxacin, and ofloxacin are available in ophthalmic forms for infections in the eyes. 

URINARY RETENTION. If a patient receives a cholinergic drug for the treatment of urinary retention, die nurse palpates die abdomen in the pelvis area to determine if distention is present. A rounded swelling over die pelvis usually indicates retention and a distended bladder. The patient may also complain of discomfort in the lower abdomen. In addition, die nurse takes die patient s blood pressure and pulse rate... 

Frequently seen adverse reactions to dragp with anticholinergic activity include dry mouth, blurred vision, dizziness, mild nausea, and nervousness. These may become less pronounced as therapy progresses. Other adverse reactions may include skin rash, urticaria (hives), urinary retention, dysuria, tachycardia, muscle weakness, disorientation, and confusion. If any of these reactions are severe, the drug may be discontinued for several days and restarted at a lower dosage, or a different antiparkinsonism drag may be prescribed. 

ADMINISTERING DISOPYRAMIDE. Because of the cholinergic blocking effects of disopyramide (see Chap. 25), urinary retention may occur. The nurse monitors the urinary output closely, especially during the initial period of therapy. If the patient s intake is sufficient but the output is low, the lower abdomen is... 

This chapter discusses drug s used to treat urinary tract infections (UTIs) and certain miscellaneous drag > used to relieve the symptoms associated with an overactive bladder (involuntary contractions of the detrusor or bladder muscle). Structures of the urinary system that may be affected include the bladder (cystitis), prostate gland (prostatitis), the kidney, or the urethra (see Pig. 47-1). These drug s also help control the discomfort associated with irritation of the lower urinary tract mucosa caused by infection, trauma, surgery, and endoscopic procedures.

Often, absorption occurs by multiple routes in humans. Dean et al. (1984) reported deaths and toxic effects as well as lowered blood cholinesterase levels and excretion of urinary 4-nitrophenol in several children who were exposed by inhalation, oral, and possibly dermal routes after the spraying of methyl parathion in a house. In the same incident (Dean et al. 1984), absorption was indicated in adults who also excreted 4-nitrophenol in the urine, though at lower levels than some of the children, and in the absence of other evidence of methyl parathion exposure. In this study, the potential for age-related differences in absorption rates could not be assessed because exposure levels were not known and the children may have been more highly exposed than the adults. Health effects from multiple routes are discussed in detail in Section 3.2. 

Most of the toxic effects caused by methyl parathion resulted from exposure by multiple routes, especially for workers in sprayed fields or formulating facilities, or people in homes. Dean et al. (1984) reported deaths and toxic effects in several children as well as lowered blood cholinesterase levels and excretion of urinary 4-nitrophenol (adults showing no adverse effects also excreted 4-nitrophenol). 

Hyperargininemia. This defect is characterized by elevated blood and cerebrospinal fluid arginine levels, low erythrocyte levels of arginase (reaction 5, Figure 29-9), and a urinary amino acid pattern resembling that of lysine-cystinuria. This pattern may reflect competition by arginine with lysine and cystine for reabsorption in the renal tubule. A low-protein diet lowers plasma ammonia levels and abolishes lysine-cystinuria. 

An update of a previous study (Axelson et al. 1978), Axelson (1986) evaluated an expanded cohort of 1,424 men (levels of trichloroethylene exposure inferred from measured urinary metabolite concentrations) and found a significant increase in incidences of bladder cancer and lymphomas, and a lower than expected incidence of total cancer mortality. A further update of this work (Axelson et al. 1994) expanded the cohort to include 249 women, tracking cancer morbidity over 30 years, and found no correlation between exposure concentration or exposure time and cancer incidence at any site. The highest standardized incidence ratio noted in this study was 1.56 (95% Cl of 0.51-3.64) for 5 cases of non-Hodgkin s lymphoma observed in men. Although four of these cases occurred in persons exposed for at least 2 years, and 3 cases had a latency of 10 years or more, urinary levels of TCA showed that 4 of the 5 cases were exposed to the lowest levels of trichloroethylene (urinary levels of TCA 0-49 mg/L). The study authors mentioned that a urinary TCA level below 50 mg/L corresponds to a trichloroethylene exposure concentration of about 20 ppm. The study authors concluded that "this study provides no evidence that trichloroethylene is a human carcinogen, i.e., when the exposure is as low as for this study population."... 

Excretion data show that saturability of trichloroethylene metabolism occurs at lower exposure levels for rats than for mice (Dekant et al. 1986b Prout et al. 1985). In mice receiving a single oral dose of 10, 500, 1,000, or 2,000 mg/kg trichloroethylene, urinary TCA and exhaled carbon dioxide over a 24-hour period were... 

This model accurately predicted the time curves for blood concentration and urinary excretion of metabolites by male volunteers exposed to 100 ppm trichloroethylene (Sato et al. 1991). It was found that, while the amount of metabolite excretion increases with body weight, the concentration does not, because of a corresponding increase in urinary volume. Also, women and obese people, compared with slim men, have lower concentrations but longer residence times of blood trichloroethylene because of their higher fat content (Sato et al. 1991). As a consequence, the model predicted that 16 hours after exposure to trichloroethylene, one could expect a woman s blood level to be 30% higher and an obese man s level to be twofold higher than that of a slim man (Sato 1993). 

The metabolism of trichloroethylene, as measured by the levels of excreted urinary metabolites, differs significantly between men and women, although study results are inconsistent (Inoue et al. 1989 Kimmerle and Eben 1973b Nomiyama and Nomiyama 1971). It does appear, however, that women excrete more urinary TCA than do men (Kimmerle and Eben 1973b Nomiyama and Nomiyama 1971). Testosterone has been implicated as a factor in the lower absorption of trichloroethylene in male rats compared with females (Kadry et al. 1991b McCormick and Abdel-Rahman 1991), and the same effect may occur in humans.

Epidural analgesia is frequently used for lower extremity procedures and pain (e.g., knee surgery, labor pain, and some abdominal procedures). Intermittent bolus or continuous infusion of preservative-free opioids (morphine, hydromorphone, or fentanyl) and local anesthetics (bupivacaine) may be used for epidural analgesia. Opiates given by this route may cause pruritus that is relieved by naloxone. Adverse effects including respiratory depression, hypotension, and urinary retention may occur. When epidural routes are used in narcotic-dependent patients, systemic analgesics must also be used to prevent withdrawal since the opioid is not absorbed and remains in the epidural space. Doses of opioids used in epidural analgesia are 10 times less than intravenous doses, and intrathecal doses are 10 times less than epidural doses (i.e., 10 mg of IV morphine is equivalent to 1 mg epidural morphine and 0.1 mg of intrathecally administered morphine).45... 

O The lower urinary tract symptoms and signs of benign prostatic hyperplasia are due to static, dynamic, or detrusor factors. The static factor refers to anatomic obstruction of the bladder neck caused by an enlarged prostate gland. The dynamic factor refers to excessive stimulation of a-adrenergic receptors in the smooth muscle of the prostate, urethra, and bladder neck. The detrusor factor refers to irritability of hypertrophied detrusor muscle as a result of long-standing bladder outlet obstruction. 

Surgical intervention should be reserved for patients with severe lower urinary tract symptoms of benign prostatic hyperplasia or those with complications of disease (such as recurrent urinary tract infections, renal failure, and bladder calculi).
