Understand advantages/disadvantages of suprapubic tubes and the standard procedure for their replacement. Introduction: the two fundamental purposes of the bladder are to store and empty urine. If a person is unable to empty his or her bladder, significant sequelae will result, including but not limited to suprapubic pain/discomfort, hydronephrosis, renal insufficiency, bladder damage and infection. In settings of urinary retention, obstruction can be relieved with simple drainage of the bladder; this can be accomplished in various ways, all of which must take into account the particular patients presenting history and clinical situation. Iatrogenic and patient initiated bladder catheterization injuries are a source of significant cost and patient morbidity. Understanding fundamental concepts behind bladder drainage gives the provider the ability to safely manage what can sometimes be an urgent patient care issue. Indications for Foley Catheter Placement Knowing when to place a Foley catheter is just as important as utilizing proper technique for its insertion. Careful patient selection is paramount because catheter placement can be associated with urethral trauma and complications, as we will discuss in ensuing sections. Of note, placement of an indwelling catheter is different from a straight catheterization procedure; the latter involves a catheter that is inserted and then removed for transient decompression and drainage of the bladder or to obtain a clean-catheterized urine specimen. In contrast, an indwelling Foley catheter is semi-permanent to allow for continuous, passive urinary drainage. In general, candidates for an indwelling Foley catheter have the following conditions/ presentations as listed below. It is usually caused by prostatic enlargement, outflow obstruction such as from strictures, or atonic bladder disorders. When present, bilateral hydronephrosis is frequently associated with chronic urinary retention. These patients often require a 3-Way Foley catheter, which allows for continuous bladder irrigation with simultaneous drainage. Contraindications to Foley Catheter Placement: Urethral catheter placement is absolutely contraindicated in cases of known or suspected urethral injury, such as in the setting of a pelvic fracture. On physical exam, gross hematuria, blood at the urethral meatus, perineal ecchymosis, and a high-riding prostate on digital rectal exam are signs that are associated with urethral trauma. A retrograde urethrogram should be performed in these cases prior to any attempt at urethral catheterization. A relative contraindication would be the presence of an artificial urinary sphincter which would need to be deactivated prior to any attempts at urethral catheterization. The most common contraindication to Foley catheter placement is actually not having an adequate indication for its insertion in the first place. For example, urinary incontinence by itself is not considered an adequate indication for a Foley catheter in most cases. The Different Catheter Types Catheters come in sizes that measure the outside circumference in mm. The French size, as well as the recommended filling volume of the catheters retention balloon (in cc or mL), is listed on the plastic cuff of the catheter sidearm (the arm of the Foley where the balloon is inflated). A typical catheter size for an adult patient is 14, 16, or 18 Fr with an associated 5 or 10 cc balloon. Straight Catheters- this is a traditional simple catheter, and often the type that is provided within in-patient catheter insertion kits. Most catheters are made of silicone or latex but some straight catheters are also made from vinyl which tends to be stiffer and more rigid. This is also the type of catheter used for intermittent self-catheterizations and for urethral self-dilations that some patients are asked to perform periodically for urethral strictures. Coude Catheters- Coude is French for the word elbow, which is used to describe the curved tip of this catheter. For many, a 16 or 18 Fr coude catheter is the go-to catheter in men with a known history of benign prostatic hypertrophy or any history of prostatic surgery. The hematuria catheter tends to be more rigid and some even have metal coils spanning the catheters circumference to tent open the lumen and facilitate hand irrigation of clots when required. These hematuria catheters also come in larger sizes (22-24 Fr) to prevent obstructions from blood clots; and they have larger associated balloons (approximately 30 cc) to allow for tamponade of the prostate when the catheter is placed on traction.

In 1 trial buy 960 mg trimethoprim with amex antibiotics for sinus infection how long, maximal inhibition of lamotrigine clearance was reached at valproate doses between 250 and 500 mg/day and did not increase as the valproate dose was further increased discount trimethoprim 960mg amex bacteria kingdom. Zonisamide In a study in 18 patients with epilepsy generic 960 mg trimethoprim with mastercard antibiotic associated diarrhea, coadministration of zonisamide (200 to 400 mg/day) with lamotrigine (150 to 500 mg/day for 35 days) had no significant effect on the pharmacokinetics of lamotrigine buy generic trimethoprim 960 mg antibiotic for sinus infection cefdinir. Known Inducers or Inhibitors of Glucuronidation Drugs other than those listed above have not been systematically evaluated in combination with lamotrigine. Since lamotrigine is metabolized predominately by glucuronic acid conjugation, drugs that are known to induce or inhibit glucuronidation may affect the apparent clearance of lamotrigine and doses of lamotrigine may require adjustment based on clinical response. Results of in vitro experiments suggest that clearance of lamotrigine is unlikely to be reduced by concomitant administration of amitriptyline, clonazepam, clozapine, fluoxetine, haloperidol, lorazepam, phenelzine, sertraline, or trazodone. Specific Populations Patients with Renal Impairment: Twelve volunteers with chronic renal failure (mean creatinine clearance: 13 mL/min, range: 6 to 23) and another 6 individuals undergoing hemodialysis were each given a single 100-mg dose of lamotrigine. Patients with Hepatic Impairment: the pharmacokinetics of lamotrigine following a single 100-mg dose of lamotrigine were evaluated in 24 subjects with mild, moderate, and severe hepatic impairment (Child-Pugh classification system) and compared with 12 subjects without hepatic impairment. The subjects with severe hepatic impairment were without ascites (n = 2) or with ascites (n = 5). The mean apparent clearances of lamotrigine in subjects with mild (n = 12), moderate (n = 5), severe without ascites (n = 2), and severe with ascites (n = 5) liver impairment were 0. Mean half-lives of lamotrigine in subjects with mild, moderate, severe without ascites, and severe with ascites hepatic impairment were 46 20, 72 44, 67 11, and 100 48 hours, respectively, as compared with 33 7 hours in healthy controls [see Dosage and Administration (2. Pediatric Patients: the pharmacokinetics of lamotrigine following a single 2-mg/kg dose were evaluated in 2 studies in pediatric subjects (n = 29 for subjects aged 10 months to 5. Lamotrigine pharmacokinetic parameters for pediatric patients are summarized in Table 16. The oral clearance of lamotrigine was higher, on a body weight basis, in pediatric patients than in adults. Weight-normalized lamotrigine clearance was higher in those subjects weighing <30 kg compared with those weighing >30 kg. These analyses also revealed that, after accounting for body weight, lamotrigine clearance was not significantly influenced by age. Thus, the same weight-adjusted doses should be administered to children irrespective of differences in age. Estrogen-containing oral contraceptives, rifampin, and the protease inhibitors lopinavir/ritonavir and atazanavir/ritonavir have also been shown to increase the apparent clearance of lamotrigine [see Drug Interactions (7)]. Geriatric Patients: the pharmacokinetics of lamotrigine following a single 150-mg dose of lamotrigine were evaluated in 12 elderly volunteers between the ages of 65 and 76 years (mean creatinine clearance = 61 mL/min, range: 33 to 108 mL/min). However, during dose escalation of lamotrigine in 1 clinical trial in patients with epilepsy on a stable dose of valproate (n = 77), mean trough lamotrigine concentrations unadjusted for weight were 24% to 45% higher (0. Racial or Ethnic Groups: the apparent oral clearance of lamotrigine was 25% lower in non-Caucasians than Caucasians. The highest doses tested are less than the human dose of 400 mg/day on a body surface area 2 (mg/m) basis. Lamotrigine was negative in in vitro gene mutation (Ames and mouse lymphoma tk) assays and in clastogenicity (in vitro human lymphocyte and in vivo rat bone marrow) assays. No evidence of impaired fertility was detected in rats given oral doses of lamotrigine up to 2 20 mg/kg/day. The highest dose tested is less than the human dose of 400 mg/day on a mg/m basis. The patients experienced at least 4 simple partial-onset, complex partial-onset, and/or secondarily generalized seizures during each of 2 consecutive 4-week periods while receiving carbamazepine or phenytoin monotherapy during baseline. Trial endpoints were completion of all weeks of trial treatment or meeting an escape criterion. Criteria for escape relative to baseline were: (1) doubling of average monthly seizure count, (2) doubling of highest consecutive 2-day seizure frequency, (3) emergence of a new seizure 54 type (defined as a seizure that did not occur during the 8-week baseline) that is more severe than seizure types that occur during study treatment, or (4) clinically significant prolongation of generalized tonic-clonic seizures. The primary efficacy variable was the proportion of patients in each treatment group who met escape criteria. The difference in the percentage of patients meeting escape criteria was statistically significant (P = 0. In all 3 trials, change from baseline in seizure frequency was the primary measure of effectiveness. The results given below are for all partial-onset seizures in the intent-to-treat population (all patients who received at least 1 dose of treatment) in each trial, unless otherwise indicated. The median seizure frequency at baseline was 3 per week while the mean at baseline was 6. One trial (n = 216) was a double-blind, placebo-controlled, parallel trial consisting of a 24-week treatment period. Patients could not be on more than 2 other anticonvulsants and valproate was not allowed. The seizure frequency reduction was statistically significant in the 500-mg/day group compared with the placebo group, but not in the 300-mg/day group. A second trial (n = 98) was a double-blind, placebo-controlled, randomized, crossover trial consisting of two 14-week treatment periods (the last 2 weeks of which consisted of dose tapering) separated by a 4-week washout period. The third trial (n = 41) was a double-blind, placebo-controlled, crossover trial consisting of two 12-week treatment periods separated by a 4-week washout period. No differences in efficacy based on age, sex, or race, as measured by change in seizure frequency, were detected. Target doses were designed to approximate 5 mg/kg/day for patients taking valproate (maximum dose: 250 mg/day) and 15 mg/kg/day for the patients not taking valproate (maximum dose: 750 mg/day). The primary efficacy endpoint was percentage change from baseline in all partial-onset seizures. Patients were dosed on a fixed-dose regimen based on body weight and valproate use.
