  • Percutaneous Endoscopic Gastrostomy in Pediatric Patients
    3 Percutaneous Endoscopic Gastrostomy in Pediatric Patients Omar I. Saadah Department of Pediatrics, Faculty of medicine, King Abdulaziz University Saudi Arabia 1. Introduction Adequate nutrition is important in the management of children with chronic illnesses. Patients who are unwilling or unable to eat will starve. Starvation depletes tissue stores, and ultimately leads to impaired organ function and tissue structure. Appropriate caloric intake enables growth, promotes tissue repair, and improve immune function. Access to the intestinal tract may be via a nasal tube or by the percutaneous route, with delivery to the stomach or jejunum. Nasogastric tubes are employed for short- term feeding, usually up to four weeks. In children requiring long term tube feeding, nasogastric feeding may be uncomfortable, disfiguring and often traumatic. Percutaneous access is usually by either endoscopic or radiological techniques. Percutaneous gastrostomy is basically a sutureless approximation of the stomach to the abdominal wall. The percutaneous endoscopic gastrostomy (PEG) becomes the most popular technique nowadays. The first PEG was performed in the pediatric operating room of University Hospitals of Cleveland on June 12, 1979 on a four-and-half-month-old child with inadequate oral intake. The procedure was performed under sedation and local anesthesia. The child did remarkably well. However, because the initial tube used was a 12F catheter with small mushroom head, external migration ensued after 3 weeks. The catheter was changed under direct visualization, using a small laparotomy (Gauderer, 2002). Since then the procedure has been adopted worldwide for both children and adults. Because the procedure is considered minimally invasive, rapid, and associated with low risk of complications, and short hospital stay, it has become the preferred method for delivering nutritional support in vulnerable pediatric patients.

Email: [email protected]. Abstract: Percutaneous tracheostomy and gastrostomy are some of the most commonly performed procedures at bedside in the intensive care unit. While they are generally considered safe, they can be associated with numerous short and long-term complications, many of which can occur long after their placement and cause significant morbidity. Performers of these procedures should possess a comprehensive understanding of procedural indications and contraindications, and know how to recognize and manage complications that may arise. In this review, we highlight complications of percutaneous tracheostomy and describe strategies for their prevention and management, with a special focus on post-tracheostomy

Methods: Neonatal Nutritional Screening Tool (NNST) was prospectively applied to all infants in the NICU within 24 hours of their hospitalization. The predictive effects of NNST and birth weight on LOS and PN administration were evaluated with Poisson regres- sion analysis. The study protocol was approved by the local Ethics Committee. Results: Total of 303 patients with a mean gestational age of 35 weeks and 2 days and a mean birth weight of 2552 g were prospec- tively included in the study. According to the NNST, 27 (8.9%) of the patients had a high risk, 70 (23.1%) had a moderate risk, and 206 (68.0%) had a low nutritional risk. However, PN treatment was initiated in 118 (38.9%) of the patients. Even though, the mean LOS was 14 days for all patients, LOS was 2.7 times higher in patients with a high nutritional risk compared to patients with a low nutritional risk (p<0.001).

  • Trends and Outcomes of Percutaneous Endoscopic Gastrostomy in Hospitalized Patients with Malignant and Nonmalignant Ascites: a Nationwide Population Study

Kadkhodayanf Creighton University / St. Joseph’s Hospital and Medical Center, Phoenix, AZ; Rutgers Robert Wood Johnson University Hospital, New Brunswick, NJ; Saint Barnabas Medical Center, Livingston, NJ; University of Cincinnati, Cincinnati, OH; Valleywise Health, USA Abstract Background Patients with ascites resulting from chronic debilitating diseases often require non-oral enteral nutrition and undergo placement of a percutaneous endoscopic gastrostomy (PEG) tube. The aim of our study was to assess the nationwide trends and outcomes of PEG tube placement among patients with ascites. Methods Using the Nationwide Inpatient Sample (NIS), we conducted a retrospective analysis of adult patients (≥18 years) who underwent PEG tube placement (n=789,167) from 2010-2014. We divided these patients into 2 groups: with or without ascites. We compared demographics, complications, and in-hospital outcomes between the groups. STATA-13 was used for statistical analysis. Statistical significance was assigned at P<0.05. Results Patients with ascites who underwent PEG tube placement were found to have a significantly higher rate of complications, including peritonitis (7.52 vs. 0.72%; P<0.001), aspiration pneumonia (20.41 vs. 2.69%; P<0.001), hemoperitoneum (0.72 vs. 0.19%; P<0.001), procedure-related hemorrhage (1.69 vs. 0.9%; P<0.001) and esophageal perforation (0.51 vs. 0.47%; P<0.001).

  • Hospitalist Care of the Medically Complex Child
    Pediatr Clin N Am 52 (2005) 1165–1187 Hospitalist Care of the Medically Complex Child Rajendu Srivastava, MD, FRCP(C), MPHa,b,*, Bryan L. Stone, MDa, Nancy A.

Over the past decade, several factors have converged to influence the kinds of children currently being hospitalized. Managed care organizations have been under increasing pressure to control costs and reduce unnecessary prolonged hospital stays. Many emergency departments are using observational units to avoid hospitalizations while reserv- ing inpatient wards for higher acuity and complex patients [1]. There has been a shift in the perception in the minds of clinicians as to what constitutes an appro- priate hospital stay and what may be treated on an outpatient basis. Therapies such as home oxygen for certain pediatric conditions (eg, bronchiolitis) and home intravenous therapy for fluids and medications are being used increasingly. These developments have produced a shift in the relative proportion of otherwise healthy children with simple, self-limited acute illness being hospitalized to children with chronic illnesses presenting with acute exacerbations or conse- quences of their underlying illnesses being cared for in the hospital [2]. This article focuses on hospitalist care of these medically complex children (MCC) and provides an overview on (1) the challenges in defining this population, (2) the unique issues surrounding their inpatient care (using a family-centered care approach that includes coordinated care, minimizing secondary complications, nutritional needs, functional limitations, transdisciplinary collaboration, and pri- * Corresponding author.
