Pharmacogenetics seeks to elucidate the variations in individual's genetic sequences in order to better understand the differences seen in pharmacokinetics, drug metabolism, and efficacy between patients. This area of research is rapidly accelerating, aided by the use of novel and more economical molecular technologies. A substantial evidence base is being generated with the hopes that in the future it may be used to generate personalised treatment regimens in order to improve patient comfort and safety and reduce incidences of morbidity and mortality.

Abstract Adequate local anaesthetic, in harvesting a split thickness skin graft (SSG), involves multiple passes of a needle across the length and width of the marked donor site. We describe a technique using hyaluronidase to uniformly anaesthetise an SSG donor site with one injection, in one pass of one needle. Mix 10mls 1% Lidocaine solution with Adrenaline 1:200,000 with 1 vial Hyaluronidase 1 Unit/ml solution. The mixture is buffered with 1 ml NaHCO3 to neutralise acidity and minimise pain. Mark out the SSG donor site Using a 27G long needle (sterican), enter perpendicular to the skin in the middle of the proximal aspect of the donor site. Inject some local anaesthetic subdermally, creating a mound. Change the angle of the needle to 180 degrees and continue to inject the remaining anaesthetic along one half of the width of the donor site. Using a rolled 4x4 swab, apply firm advancing pressure to distribute the mound across the remaining width and length of marked donor site. As the mound advances, the hyluronidase/anaesthetic mixture will distribute uniformly across the donor site within the same plane. The skin blanches secondary to the adrenaline during its distribution. The technique described is a fast, reproducible way to improve patient comfort through the elimination of repeated passes of a needle, distribute the anaesthetic uniformly across the donor site, and facilitate the acquisition of an SSG of uniform thickness The technique described is a fast, reproducible way to improve patient comfort through the elimination of repeated passes of a needle, distribute the anaesthetic uniformly across the donor site, and facilitate the acquisition of an SSG of uniform thickness

BACKGROUND: Low-tube voltage scanning improves CT attenuation value of contrast medium (CM). Thus, we hypothesized that 70 kVp in pediatric abdominal CT angiography (CTA) could be used to reduce both radiation and CM dose and improve patient comfort at the same time. OBJECTIVE: To evaluate the feasibility of using 70 kVp in pediatric abdominal CTA to reduce radiation dose and CM dose and improve patient care for children. MATERIALS AND METHODS: Forty-six children needing abdominal CTA were enrolled in the study group using low-dose scanning protocol with 70 kVp and 0.7–1.1 ml/kg contrast dose, and reconstructed with 50%ASIR-V. They were compared with other 46 children in control group with matching body weight and underwent conventional CT scans with 100 kVp, 1.2–1.8 ml/kg contrast dose and reconstructed using 50%ASIR. Image quality of large vessels was evaluated using a 5-point scale. CT value and standard deviation of descending aorta (Ao) was measured, and signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated. Radiation dose, contrast dose, the maximum injection pressure between the two groups were also compared. RESULTS: Score for displaying large vessels by 70 kVp images was 3.91±0.28, lower than that (4.17±0.38) of the control group (p <  0.05), but fully met the diagnostic requirements. CT value of Ao was 390.87±86.79HU in study group, which is higher than 343.93±49.94HU in control group, while there was no difference in SNR and CNR between two groups; the radiation dose, contrast dosage and injection pressure of the study group were 1.23±0.39mGy, 12.67±7.27 ml and 43.83±17.16psi, respectively, which are significantly lower than the 1.95±0.37mGy, 22.67±7.39 ml, and 77.59±19.68psi of control group. CONCLUSION: Use of 70 kVp in pediatric abdominal CTA provides diagnostic quality images while significantly reduce radiation and contrast dose, as well as injection pressure to improve patient comfort for children.

Patient–Ventilator Interactions and Asynchrony describes what happens when the patient and the ventilator do not work together in an effective, coordinated manner. Effective mechanical ventilation requires the synchronized function of two pumps: The mechanical ventilator is governed by the settings chosen by the clinician; the patient’s respiratory system is controlled by groups of neurons in the brain stem. Ideally, the ventilator simply augments and amplifies the activity of the respiratory system. Asynchrony between the ventilator and the patient reduces patient comfort, increases work of breathing, predisposes to respiratory muscle fatigue, and may even impair oxygenation and ventilation. The chapter describes the causes and consequences of patient–ventilator asynchrony during ventilator triggering and the inspiratory phase of the respiratory cycle and explains how to adjust ventilator settings to improve patient comfort and reduce the work of breathing.
