The clinical pharmacist on the team is responsible for ensuring safe and effective medication use for all patients admitted to the pediatric and neonatal intensive care unit. Routine responsibilities include: review and confirmation of appropriateness of medication for the patient population based upon age, weight, indication and pharmacokinetic considerations; completion of consults and medication therapy protocols in areas including dosing and monitoring of TPN, kinetics, evaluation of anti-infectives, addressing formal consults for non-formulary drug requests and providing patient and family education. The pharmacist also provides drug information and education to healthcare professionals as requested. Expectations of the Resident Residents will attend NICU and Pediatric rounds every day. During this rotation the resident will focus on caring for patients in the pediatric and neonatal intensive care units. Residents will actively seek to identify the potential for significant medication-related

  • Treatment of ARDS*
    Treatment of ARDS* Roy G. Brower, MD; Lorraine B. Ware, MD; Yves Berthiaume, MD; and Michael A. Matthay, MD, FCCP Improved understanding of the pathogenesis of acute lung injury (ALI)/ARDS has led to important advances in the treatment of ALI/ARDS, particularly in the area of ventilator- associated lung injury. Standard supportive care for ALI/ARDS should now include a protective ventilatory strategy with low tidal volume ventilation by the protocol developed by the National Institutes of Health ARDS Network. Further refinements of the protocol for mechanical ventilation will occur as current and future clinical trials are completed. In addition, novel modes of mechanical ventilation are being studied and may augment standard therapy in the future. Although results of anti-inflammatory strategies have been disappointing in clinical trials, further trials are underway to test the efficacy of late corticosteroids and other approaches to modulation of inflammation in ALI/ARDS.

  • Very Low Birth Weight Infants
    Intensive Care Nursery House Staff Manual Very Low and Extremely Low Birthweight Infants INTRODUCTION and DEFINITIONS: Low birth weight infants are those born weighing less than 2500 g. These are further subdivided into: •Very Low Birth Weight (VLBW): Birth weight <1,500 g •Extremely Low Birth Weight (ELBW): Birth weight <1,000 g Obstetrical history (LMP, sonographic dating), newborn physical examination, and examination for maturational age (Ballard or Dubowitz) are critical data to differentiate premature LBW from more mature growth-retarded LBW infants. Survival statistics for ELBW infants correlate with gestational age. Morbidity statistics for growth-retarded VLBW infants correlate with the etiology and the severity of the growth-restriction. PREVALENCE: The rate of VLBW babies is increasing, due mainly to the increase in prematurely-born multiple gestations, in part related to assisted reproductive techniques. The distribution of LBW infants is shown in the Table: ________________________________________________________________________ Table. Prevalence by birth weight (BW) of LBW babies. Percentage of Percentage of Births Birth Weight (g) Total Births with BW <2,500 g <2,500 7.6% 100% 2,000-2,500 4.6% 61% 1,500-1,999 1.5% 20% 1,000-1,499 0.7% 9.5% 500-999 0.5% 7.5% <500 0.1% 2.0% ________________________________________________________________________ CAUSES: The primary causes of VLBW are premature birth (born <37 weeks gestation, and often <30 weeks) and intrauterine growth restriction (IUGR), usually due to problems with placenta, maternal health, or to birth defects. Many VLBW babies with IUGR are preterm and thus are both physically small and physiologically immature. RISK FACTORS: Any baby born prematurely is more likely to be very small.

  • Use of Blood Components in the Newborn
    NNF Clinical Practice Guidelines Use of Blood Components in the Newborn Summary of recommendations • Transfusion in the newborn requires selection of appropriate donor, measures to minimize donor exposure and prevent graft versus host disease and transmission of Cytomegalovirus. • Component therapy rather than whole blood transfusion, is appropriate in most situations. • A clear cut policy of cut-offs for transfusions in different situations helps reduce unnecessary exposure to blood products. • Transfusion triggers should be based on underlying disease, age and general condition of the neonate. Writing Group : Chairperson: Arvind Saili ; Members: RG Holla, S Suresh Kumar Reviewers: Neelam Marwaha, Ruchi Nanawati Page | 129 Downloaded from www.nnfpublication.org NNF Clinical Practice Guidelines Introduction Blood forms an important part of the therapeutic armamentarium of the neonatologist. Very small premature neonates are amongst the most common of all patient groups to receive extensive transfusions.
