Other possible radionuclidic contaminants of the 99mTc eluate arise from impurities in the 99Mo used and will vary according to the method used in its production. Molybdenum-99 produced by fission of 235U can contain very small amounts of 131I, 103Ru and nuclides of strontium that are not likely to be present in 99Mo which is produced by neutron irradiation of 98Mo. The measurement of these impurities normally has to be performed on an eluate that has been allowed to decay sufficiently, and also requires specialized equipment that is likely to be beyond the means of routine radiopharmacy and nuclear medicine departments. For many radiopharmaceuticals the radiochemical purity will be expected to be greater than 95%, but this is not universally so. For radiopharmaceuticals purchased in their final form, manufacturers will normally declare the radiochemical purity and the radiopharmacy may not need to perform any further determinations. For materials prepared in-house, either totally from original materials or purchased kits, radiochemical purity determinations are useful to establish the suitability of the final product. Low radiochemical purities may lead to an unintended biodistribution of the radiopharmaceutical. For diagnostic agents, this may lead to confusion in the diagnosis and for therapeutic radiopharmaceuticals it can produce significant dosimetric problems. A range of techniques is available for such determinations, but the techniques must be reliable and simple, and preferably rapid, to perform such that, in an ideal situation, the radiochemical purity of materials containing short lived radionuclides can be established prior to their administration. The simplest and most widely used technique is that of planar chromatography, using suitable stationary phases. The choice of stationary and mobile phases is determined by the nature of the radiopharmaceutical, and must be such that the various radiochemical species 502 7. The techniques can be carried out with very simple apparatus, for example with beakers or measuring cylinders as chromatography tanks; in view of the scale of the operation only small volumes of solvent are needed. The levels of each species can be determined by scanning the stationary phase with a suitable detector or cutting it into sections and placing each in a counter. However, the limitations of these simple systems need to be borne in mind, since in many of them only certain impurities. Most of the activity may remain at the point of application on the chromatography strip and thus be unresolved. The determination is therefore more correctly described as radiochemical impurity determination, since the exact chemical nature of the species remaining at the point of application has not been determined. The technique utilizes the separating power of adsorbent materials packed into stainless steel columns through which a solvent is pumped at high pressure. Different radiochemical species are identified by monitoring the eluate from the column and noting the time at which radioactivity is detected. This technique has limitations in that the apparatus is expensive and may not be routinely available to hospital radiopharmacies. In addition, certain radiochemical species, for example hydrolyzed reduced Tc in Tc radiopharmaceuticals, may be retained on the column used to achieve the separation and may not therefore be accounted for in the analysis. By using appropriate eluents, different species can be selectively removed from the cartridge and, providing a sufficiently high radioactive concentration is used, activity can be determined with a dose calibrator or other simple scaler. The most likely situation to be met in radiopharmacies is the presence of Al ions in Tc radiopharmaceuticals. Very high levels of Al can be toxic to patients, but it is unlikely that such problems will arise from administration of a radiopharmaceutical. However, lower levels can adversely affect radiopharmaceutical formation or stability, for example of colloidal radiopharmaceuticals, where the trivalent Al cation can alter the surface charge of particles and lead to aggregation and hence an altered biodistribution. Aluminium can be detected by a simple colorimetric limit test, using either a solution or indicator strips containing an Al sensitive marker such as chromazurol S. By comparing the colour obtained with a small volume of the eluate of a Tc generator and that from a solution containing a specified concentration of Al ions (generally 5 or 10 parts per million), it can be determined that the Al content of the eluate is below the specified level and hence suitable for use. Particle size can be determined by light microscopy, using a graduated slide to ensure that there are no oversize particles and that a suitable range of sizes is present. The limitations of the method are that it is usually only possible to observe a limited number of particles and that prolonged observation subjects the eyes to an increased radiation burden. These limitations can be overcome by reconstituting a macroaggregate kit with saline and observing non-radioactive particles. Colloidal particles cannot be visualized by normal light microscopy and, in situations where it is important to know the particle size distribution, more elaborate techniques such as light scattering or membrane filtration will have to be used. The use of clean glassware, kits, reagents and equipment is the best way to minimize contamination. However, on occasions, particles can be present in the final solution as a result of coring of the rubber 504 7.

In addition to developing tighter controls over opioids and other drugs with abuse potential, systems must be designed to detect diversion of controlled substances as early as possible. We describe the development of a semi-automated surveillance system designed to detect fentanyl administration patterns suspicious for diversion. A secondary criterion of concomitantly high median percentile rank was subsequently applied to reduce the false positive rate. In addition to the three known diverting providers the algorithm identified 14 false positives and 265 true negatives. The cases of diversion were detected 0, 3, and 17 months prior to their removal from clinical practice. There were, however, false positives in the analysis that would require approximately five investigations for every true case of diversion. Considering the consequences of undetected diversion this additional investigative effort may be justifiable, however it must be balanced with the possible consequences of investigating non-diverting providers. For some sessions, material was doubled up, but a fair amount of material from year 1 was not part of the year 2 curriculum. A 2 hour 10 minute exam was administered at the beginning of the program, after the first year, and after the second year. The exam was created by 3 experienced cardiac anesthesiologists, and consisted of 20 video clips (worth 1. In Japan, a four-week anesthesiology rotation is required of medical interns in the first year. We investigated whether four-week anesthesiology training increased intubation success rate and reduced mental stress related to intubation. First, we conducted a questionnaire survey on intubation success rate and the stress of intubation before anesthesiology training. Second, we investigated rate of success rate with intubation and mental stress related to intubation during anesthesiology training. Intubation cases were allocated randomly, and intubation success rate and Cormack grade were examined. Furthermore, there was a significantly higher number of cases judged Cormack grade I for second-year interns than for firstyear interns (P=0. However, although intubation success rate was obviously improved, mental stress related to intubation was not reduced. The reason for this appeared to be that four-week training was insufficient to gain confidence with intubation. Experience in four-week anesthesiology training improved intubation success rates, but was not successful in reducing mental stress related to intubation. In addition to the primary hypothesis, we examined the possibility that there is a correlation between preoperative anxiety and the propofol consumption. We were hoping that answering these two questions will assist us with improving patient perioperative experience. All patients were instructed to use the self administered propofol pump as needed. The pump was programmed to a demand dose of 100 mcg/kg and lock-up interval of 5 minutes without basal infusion. Using Kruskal-Wallis one way analysis of variance showed a statistically significant difference between the groups (P=0. This can be attributed to higher level of attention distraction during the surgery. Surprisingly, the propofol consumption was higher in the music group compared to the control group. Language barriers can lead to miscommunication, mistrust, avoidance of medical care and heightened anxiety about the unknown. As medical interpreter services are scarce, patients who opt to use family members as interpreters may not receive the exact message that is intended from the medical team. Using a 1-10 scale, all patients were asked in Spanish to describe their anxiety associated with general anesthesia, knowledge about anesthetic procedures, and satisfaction with the information about general anesthesia they had received in the preoperative clinic. On the day of surgery, all patients had the routine pre-anesthesia interview involving use of a medical interpreter or family member. Prior to this interview, group V saw a three-minute educational video explaining in Spanish the procedures, risks and benefits accompanying a general anesthetic. Both groups were then asked the same questions about anxiety, knowledge, and satisfaction.

There is increase in incidence of clinically less severe epiglottitis, with negative sputum cultures in adults. Selective airway intervention is possible in adults as those without severe airway compromise at presentation may recover well with medical treatment alone. Stridor in adults is regarded as a warning sign for occlusion of the upper airway. In this patient, despite the absence of stridor, a fast intervention by securing the airway under controlled conditions was justified considering hoarseness, dysphagia and a "thumb sign" on radiography. Criteria for selective airway intervention are not well defined in the adolescent patient with epiglottitis. Significant predictors for imminent airway compromise may include drooling, stridor, and shortness of breath or "thumbsign" present in 79% of cases on X-rays of the neck. In the absence of a positive radiological finding, performing a flexible fiberoptic laryngoscopy for a timely diagnosis should be done cautiously. Deep sedation is when a patient only responds to painful stimulation, while moderate sedation is when a patient is arousable to verbal stimulation. We included the following journals: Anesthesiology, Anesth Analg, J Clin Anesth, Can J Anaesth, Br J Anaesth, J Anesth, Paediatr Anaesth, Eur J Anaesthesiol. The danger is the potential for non-anesthesia trained providers to use techniques studied as "sedation" when they are general anesthesia.

Data was abstracted by each centre and sent to the coordinating centre for aggregation and analysis. Any strategy that reduces this risk would improve patient safety and may allow for larger dosing regimens and associated clinical benefits. A pharmacy research technician, blind to anaesthetic group, employs high pressure liquid chromatography6 and ultrafiltration7,8 to determine total and free bupivacaine concentrations. Longitudinal human neurodevelopmental outcome studies after exposure to anesthesia are limited, with no clear data on whether and which specific neurocognitive domains are affected. We used a prospective birth cohort of children who had undergone longitudinal neuropsychological testing to determine the effects of anesthetic exposure in a wide range of neurocognitive domains. We conducted t-tests and 2 tests to compare exposed and unexposed on demographic and outcome variables with p< 0. Thus, language and abstract reasoning are two major areas to focus on for hypothesis testing in future studies of developmental neurotoxicity in the setting of anesthesia and surgery. One clue in elucidating unique mechanisms of obesity between children and adults has been the finding that rates of metabolic syndrome in pre-pubertal girls and boys are similar, while the rate of metabolic disease in post-pubertal boys is significantly higher than is seen in post-pubertal girls. This scenario was maintained until mice were 10 weeks of age at which time pair feeding was released and all animals were allowed unlimited access to food. And second, caloric moderation, a major component of weight-loss strategy, may be ineffective in inducing reduction of adiposity when initiated in pre-pubescent girls. Demographic data and clinical data during the perioperative period were obtained from a review of anesthesia and medical records. The following complications were identified: documented oxygen desaturation (desat), postoperative infection/ sepsis, and post-op mechanical ventilation (mech). Patients with associated anomalies, complicated birth, or missing data were excluded. However, because the low incidence of gastrochisis, our sample size was small, and our findings will need further confirmation with larger sample sizes. Non-taping techniques were used to secure the airway and intravenous (iv) catheters, and soft padding was placed beneath the blood pressure cuffs. The majority of children received an iv induction of anesthesia with propofol (54. Maintenance of anesthesia was usually with iv propofol (50%) or propofol/ketamine (28. In 31 of the 42 anesthetics (74%) spontaneous ventilation without intubation or oral airway devices was utilized.

The parents are subsequently required to continue with serially larger dilators until the appropriate size is achieved. Contrast enema can show a transition zone, where the rectum has a smaller diameter than the sigmoid colon. Definitive diagnosis is made by finding aganglionosis and hypertrophied nerve trunks on a suction rectal biopsy. Initial management should involve nasogastric or orogastric decompression and fluid management. The initial goal of therapy is decompression by either rectal irrigations or colostomy. As the testicle descends during the final trimester from its intra-abdominal position into the scrotum, a portion of the processus surrounding the testes becomes the tunica vaginalis. If the portion of the processus vaginalis in the canal persists, this creates the potential for a hernia. Fluid may be trapped in the portion of the processus surrounding the testis in the scrotum, creating a hydrocele. While most infant hydroceles resolve spontaneously within 12 to 18 months, a hernia never spontaneously resolves and requires surgery to prevent incarceration and strangulation of intra-abdominal structures and irreversible damage to the testes. The younger the infant, the higher the risk that the hernia will become incarcerated. Thirty-one percent of incarcerated hernias occur in infants less than 2 months of age. Risk factors for increased incidence of hernia in infants include: Inguinal Hernia pass meconium by 48 hours. Prenatal history may include polyhydramnios with dilated, echogenic bowel on prenatal ultrasound. Abdominal radiographs typically show dilated airfilled loops of proximal bowel with no air in the rectum. Contrast enema may be required to rule out other diagnoses such as meconium plug, meconium ileus, and Hirschsprung disease. Post-op complications include anastomotic leak, stenosis at the site of anastomosis, and short gut syndrome. Mortality is about 10% (90% survival) with prematurity, associated anomalies, infection and short gut syndrome as major contributors to mortality. Midgut volvulus is one of the most serious emergencies during the newborn period since a delay in diagnosis and subsequent gangrene of the midgut is almost uniformly fatal. The mass may extend into the scrotum and will enlarge with increased intra-abdominal pressure (crying or straining). Incarcerated hernias in children can rapidly evolve into strangulation and gangrene of hernia contents. Intestinal Atresia Surgical consultation should be immediately obtained when the diagnosis is suspected. A few hours may be the difference between a totally reversible condition and death (loss of the entire midgut). Small bowel atresia is a congenital occlusion of the intestinal lumen secondary to an intrauterine mesenteric vascular occlusion that causes a complete obstruction. The most common associated conditions are cystic fibrosis, malrotation, gastroschisis, along with low birth weight and multiparity. Intestinal atresia has also been associated with maternal smoking and cocaine use.
