The parts of a catheter or cannula set (Figure 3) include: • A needle or stylet, with a bevelled tip and flashback chamber. The tip is tapered to facilitate insertion and prevent trauma to the vein while in place. The stylet is situated inside the catheter; it is removed when insertion is complete. The parts of a winged needle include: • Needle (metal) • Bevelled tip • Wings, which provide handles for insertion and some stability after insertion • Tubing • Protective cap • Needle sheath. The vein should be long and straight enough to accept the catheter; it should feel wide enough for blood flow to continue around the catheter after insertion. They usually involve the cephalic vein and provide circulatory access for patients receiving hemodialysis (during which a machine removes waste normally removed by the kidney, from the blood). These vessels are accessed only by specially trained hemodialysis nurses and physicians. Where possible, avoid veins: • In the inner aspect of the wrist, in order to avoid radial nerve damage • Hardened or scarred from previous use • Which are inflamed or infected • In an area over a joint. Too tight an application will restrict arterial flow; check by feeling for a radial pulse. It is surprising how many patients are aware of idiosyncrasies in their venous anatomy but are reluctant to say anything unless asked. Often, their information is helpful and it gives the patient a sense of control over the situation and a feeling of contribution. This is important to prevent rolling of the vein while you insert the catheter (or cannula). Holding the catheter set at a 30-45° angle with the bevel up, pierce the skin quickly and firmly, one-half to one centimetre below where you intend to enter the vein (Figure 5). When blood appears in the flashback chamber, withdraw the inner stylet very slightly while advancing the catheter completely into the vein. Withdrawal of the stylet allows you to observe the flashback up into the catheter while advancing with the softer, more flexible catheter tip. Grasp the hub of the catheter and remove the stylet, pressing lightly on the area above the catheter tip to prevent backflow of blood while you are connecting the tubing. Once the stylet is pulled back or removed, do not attempt to readvance or reinsert for any reason. Readvancing or reinserting could shear the catheter tip introducing it into the systemic circulation. If you have entered the tissue and have not entered the vein, you may be able to "catch" it by refeeling for the vein, restabilizing the skin below the insertion point and angling the needle toward where you palpated the vein. Essentially, you are relocating the vein with your fingertip(s) and aiming the needle toward that point. Instead, remove the tourniquet and needle, apply a Band-AidTm or gauze dressing to the site and attempt again. Remove the tourniquet, remove the needle and apply firm pressure over the site with a sterile gauze. Do not relieve the pressure until after approximately 10 minutes at which time hemostasis should have occurred. Reapplying the tourniquet to the same arm even after application of pressure, could result in rebleeding at the original site thus causing a painful hematoma. Once the cannulation is successful and the tubing connected, open the roller clamp fully to establish patency of the line and observe for infiltration at or above the site. Commence with the contrast media injection inspecting the site frequently for infiltration. The basic, necessary information is standard however and should contain: • Date and time of insertion • Site, gauge and type of needle device • Type, amount of solution hung and the rate of infusion • Additives, i. Butterfly, Scalp-Vein Sets The needle is held bevel-up by grasping one or both of the wings. Remember, cephalic and basilic veins that are observed superficially on the forearm, require a more shallow angle of insertion than do deeper veins at the antecubital fossa. Penetration of the skin and vein is generally easier with winged sets as the metal needles are extremely sharp. Before inserting the needle, loosen the cap over the end of the tubing just to loosen. This will "break the vacuum" that may occur during manufacturing and therefore will facilitate a flashback once the vein is entered. Larger veins such as those at the antecubital fossa are large enough to accept complete cannulation, however, because the needle is rigid and therefore inflexible, there presents a risk of perforating the far wall of the vein. For this reason, it is acceptable to secure the needle once flashback is observed, without attempting to advance it further into the vessel. After flashback is seen release the tourniquet and tape the needle over the winged parts to secure. If not, reapply the tourniquet and if again, freely flowing blood return is not apparent, consider the venipuncture unsuccessful. Remove the needle, apply pressure with a sterile gauze and attempt again once hemostasis has occurred. Small amounts of air that remain in the tubing may be aspirated with a syringe prior to direct injection. Tell the patient that the procedure is completed and that you will now be removing the catheter/needle. Apply light pressure with the gauze directly over the site with your non-dominant hand.
Epidemiology of anti-infective drug use during pregnancy The question of whether to prescribe anti-infective drugs to pregnant women is a dilemma faced by health care providers on a daily basis order 30gm acticin otc. Physicians have been reluctant to prescribe anti-infective drugs for pregnant women because a few of them are on the list of human teratogens (e purchase acticin 30 gm overnight delivery. There is discrepancy in results of the studies that investigated the use of anti- infective drugs during pregnancy acticin 30gm line. Therefore, useful comparisons between studies and interpretation of results can be challenging . The use of medications by pregnant women was recorded in South Africa, and the results showed that the most commonly used medicines were analgesics, antibiotics, laxatives and antacids . In Brazil, a retrospective cohort study showed that antibiotics were the third most common group of medications used during pregnancy . In Finland, penicillin, erythromycin and pivmecillinam were the most often used antibiotics during pregnancy comprising together 65. Antibiotics were the most commonly prescribed medications in a study conducted in Australia . High incidence of anti-infective use in pregnancy was also observed in the United States [4, 52], where the use of nitrofurantoin, sulfonamides was considered excessive . In the United Kingdom, 30% of women were exposed to at least one anti-infective drug during gestation . Respiratory infections diagnosed during pregnancy are mostly of viral etiology [59-61]. In this thesis, we focus on anti- infective drugs used to treat bacterial infections. These infections are characterized by the presence of microorganisms in the genito-urinary tract that cannot be explained by contamination. These agents have the potential to invade the tissues of the urinary tract and adjacent structures. The infection may be limited to the growth of bacteria in the urine (which frequently doesn’t produce symptoms) or it can result in several syndromes associated with an inflammatory response to remove the bacterial invasion. Although the incidence of acute cystitis in pregnant women is similar to that in their nonpregnant counterparts, 12 the incidence of acute pyelonephritis in pregnant women with bacteriuria is significantly increased, compared with nonpregnant women . Many studies have reported that pyelonephritis is more common during the second half of pregnancy, with an incidence peak during the last two trimesters of pregnancy [67-69]. The prevalence is also markedly increased if women present certain pre-existing medical conditions, such as diabetes mellitus, sickle cell disease, immunodeficiency states, urinary tract anatomic anomalies, spinal cord injuries and psychiatric illnesses . Organisms causing bacteriuria are similar in both pregnant and nonpregnant women . Asymptomatic bacteriuria is defined by 8 two consecutive clean-catch urine cultures with more than 10 colonies of bacteria/L of urine, with a single type of bacteria . Urethritis is characterized by urethral colonization 13 resulting in dysuria and polyuria. Common clinical manifestations are dysuria, polyuria, suprapubic discomfort, and in some cases, hematuria . Clinical signs and symptoms of pyelonephritis include flank pain or abdominal pain, fever, anorexia, nausea and vomiting often associated with variable degrees of dehydration, chills, headache, and tachypinea. Intrauterine infections are thought to be responsible for up to 50% of extreme preterm births of less than 28 weeks of gestation, where both neonatal mortality and morbidity are high . As a consequence, the initial antibiotic therapy has the drawback of being empirical, and a variety of different antimicrobial agents can be used for treatment . Urinary Treatment Treatment options Comments tract regimen infection Asymp- Current standard Cephalexin 250-500 mg, Single-dose tomatic of practice is to po, qid. Although the infection is present in almost 20% of pregnant women, it is difficult to know the exact prevalence of this condition, because many cases are asymptomatic or naturally occur at regular times during the menstrual cycle . The infection is clinically characterized by the presence of three of the five following Amsel criteria : release of the amine fishy odour, release of amine odour after addition of potassium hydroxide, vaginal pH greater than 4. Available evidence does not suggest any benefit in screening and treating asymptomatic pregnant women if the aim of therapy is to prevent preterm birth . Topical intra-vaginal treatment with clindamycin is not recommended, given that the use of this drug is associated with an increased risk of low birth 21 weight and neonatal infections [32, 102, 109-111]. This agent is able to cross the placenta throughout gestation, and data from animal studies suggests teratogenic properties for this drug . However, there is no evidence that using metronidazole during pregnancy increases the rate of major birth defects or that there are any detectable adverse effects on fetuses . Some studies suggest that the use of metronidazole during the last two trimesters of pregnancy may result in a qualitative imbalance of the normal vaginal flora [114, 115]. One of its consequences is the growth of harmful microorganisms, leading to ascending infection, stimulation of the local inflammatory process and early delivery. Therefore, the use of metronidazole during pregnancy has been controversial . Bacterial Treatment Treatment Comments vaginosis regimen options Metronidazole Current standard 500 mg po bid for Topical of practice is to 7 days. However, as with the use of other medications, the potential benefits of use need to be weighed against the risk for the fetus . Furthermore, a direct independent effect of the drug itself on pregnancy outcomes cannot be excluded. Some suggestions on the use of anti-infective drugs during pregnancy include : • Use of anti-infectives only if absolutely indicated. This includes treatment of confirmed infection, prevention of ascending infection, and prevention of early-onset neonatal sepsis; • If possible, avoid the initiation of therapy during the first trimester of gestation; • Selection of a safe medication, which often means an older drug with a proven track record of safety in pregnancy; • Single-agent therapy is preferred over polypharmacy; • Narrow-spectrum agents are preferred over those with a broad spectrum for the treatment of established infection; • Use of the lowest effective dose. Most of the available evidence on the use of anti-infective drugs during pregnancy was devoted to their potential teratogenic properties .

No carcinogenicity was detected in 2-year long-term studies in mice at exposures up to 14-fold higher than that achieved with human systemic exposure at the recommended dose, or in rats at exposures up to 10-fold higher in males and 15-fold higher in females than human exposure at the recommended dose. Early experience of dolutegravir pharmacokinetics in pregnancy: high maternal levels and signifcant foetal exposure with twice-daily dosing. A Comparison of the pharmacokinetics of dolutegravir during pregnancy and postpartum. Presented at: 18th International Workshop on Clinical Pharmacology of Antiviral Therapy. Animal studies Carcinogenicity Elvitegravir was not genotoxic or mutagenic in vitro. No carcinogenicity was detected in long-term studies in mice at exposures up to 14-fold and rats at exposures up to 27-fold that achieved with human systemic exposure at the recommended dose. Despite the low elvitegravir exposure in this woman, viral load remained undetectable throughout the pregnancy. Teratogenicity/Adverse Pregnancy Outcomes In the Antiretroviral Pregnancy Registry, insuffcient numbers of frst-trimester exposures to elvitegravir in humans have been monitored to be able to make a risk determination. Antiretroviral Pregnancy Registry International Interim Report for 1 January 1989–31 July 2016. Long-term carcinogenicity studies of raltegravir in mice did not show any carcinogenic potential at systemic exposures 1. Treatment-related squamous cell carcinoma of the nose/nasopharynx was observed in female rats dosed with 600 mg/kg/day raltegravir (exposure 3-fold higher than in humans at the recommended adult dose) for 104 weeks. These tumors were possibly the result of local irritation and infammation due to local deposition and/or aspiration of drug in the mucosa of the nose/nasopharynx during dosing. No tumors of the nose/ nasopharynx were observed in rats receiving doses resulting in systemic exposures that were 1. Teratogenicity/Adverse Pregnancy Outcomes Studies in rats and rabbits revealed no evidence of treatment-related effects on embryonic/fetal survival or fetal weights from raltegravir administered in doses producing systemic exposures approximately 3- to 4-fold higher than the exposure at the recommended adult human daily dose. In rabbits, no treatment-related external, visceral, or skeletal changes were observed. However, treatment-related increases in the incidence of supernumerary ribs were seen in rats given raltegravir at 600 mg/kg/day (providing exposures 3-fold higher than the exposure at the recommended human daily dose). In rats given a maternal dose of 600 mg/kg/day, mean fetal blood concentrations were approximately 1. However, in rabbits, the mean drug concentrations in fetal plasma were approximately 2% of the mean maternal plasma concentration at both 1 and 24 hours following a maternal dose of 1000 mg/kg/day. No effects in rat offspring were attributable to raltegravir exposure through breast milk. No signifcant difference was seen between the third trimester and postpartum trough concentrations. Given the high rates of virologic suppression and the lack of clear relationship between raltegravir concentration and virologic effect in non-pregnant adults, no change in dosing was recommended during pregnancy. One patient was below the target C12hr in the third trimester and none were below the threshold postpartum. Teratogenicity/Adverse Birth Outcomes As of January 31, 2017, seven cases with defects have been reported among 263 infants with frst-trimester exposure to raltegravir included in the Antiretroviral Pregnancy Registry. One case has been reported of drug reaction with eosinophilia and systemic symptoms syndrome with extensive pulmonary involvement in a postpartum woman that resolved with discontinuation of raltegravir. Such reactions have been reported in non-pregnant adults receiving raltegravir and should be considered in the differential diagnosis of fever during pregnancy or postpartum period in women on raltegravir. In an in vitro study of the effect of raltegravir on bilirubin-albumin binding, raltegravir had minimal effect on bilirubin-albumin binding at concentrations of 5 µM and 10 µM, caused a small but statistically signifcant increase in unbound bilirubin at 100 µM, and caused potentially harmful increases at 500 and 1000 µM.

Critical Review: Review of the effcacy, safety, and pharmacokinetics of raltegravir in pregnancy. Animal Studies Carcinogenicity At cobicistat exposures 7 times and 16 times the human systemic exposure, no increases in tumor incidence were seen in male and female mice. In rats, an increased incidence of follicular cell adenomas and/or carcinomas in the thyroid gland was observed at doses up to twice the typical human exposure. The follicular cell fndings are considered rat-specifc, and not relevant to humans. Post-dose concentrations (at 24 hours) were reduced by at least 76%; cobicistat was below detection (<10 ng/mL) in most trough samples in pregnancy. No data are available on the impact of pregnancy on the pharmaco-enhancing activity of cobicistat for other coadministered antiretroviral drugs during pregnancy, such as darunavir or atazanavir.
