Background: Various criteria exist for defining difficult intravenous access (DIVA) in infants and children. The current study evaluated the factors associated with DIVA in a prospective cohort of over 1000 infants and children presenting for anesthetic care.

Methods: This was a prospective, observational study of patients aged 0 to 18 years undergoing elective surgical or radiologic procedures under general anesthesia. Prior to the initial attempt at peripheral intravenous (PIV) cannulation, the anticipated difficulty of PIV catheter placement was determined by the provider using a visual analogue scale (VAS) from 1 to 10. The number of attempts was recorded as well as the time required to achieve PIV access. DIVA was defined as requiring three or more attempts. After successful cannulation, the actual difficulty of the PIV placement was assessed by the provider and recorded using the same VAS. Patient characteristics, including age, race, body mass index (BMI), American Society of Anesthesiologists (ASA) physical classification, and history of difficult PIV placement, were evaluated as covariates.

Results: In our cohort of 1002 pediatric patients, 78% of patients were successfully cannulated in a single attempt and 91% of patients were successfully cannulated in two or fewer attempts. Factors associated with requiring three or more PIV attempts included younger age (OR 8.73; 95% CI: 3.38, 22.6 for age <1 year and OR 4.93; 95% CI: 2.05, 11.8 for age 1-3 years), higher ASA physical classification (OR 1.95; 95% CI: 1.10, 3.46 for ASA II), and prior history of difficult PIV placement (OR 3.46; 95% CI: 1.70, 7.08). BMI, racial category or gender were not independent predictors of DIVA.

Conclusion: We found that approximately 9% of patients required three or more attempts at IV placement in the operating room. Patients that required multiple PIV attempts were more likely to be younger, have a higher ASA classification or a history of difficult PIV placement.

Background: Undernutrition and anemia in children continue to be a public health problem in developing countries. Besides, intestinal parasitic infection among school children is common in developing countries. World Health Organization (WHO) recommends periodic deworming of children who live in endemic areas. The aim of this study was to determine the magnitude of anemia and undernutrition among school children in a setting of mass deworming.

Methods: A cross-sectional study was conducted among 510 school children aged 5-14 years from three randomly selected governmental schools in Sululta town, central Ethiopia. Socio-demographic variables were assessed using interviewer administered structured questionnaire. Anthropometric data were obtained and analyzed using WHO Anthroplusv1.0.4. Venous blood samples were collected using EDTA vacutainers. Hemoglobin level was determined by Sysmex KX-21N automated hematology analyzer and stool samples were processed using direct wet mount, formol-ether concentration and Kato-Katz methods. Data were entered and analyzed using SPSS version 21. Logistic regression analysis was performed to determine the association of anemia and undernutrition with the independent variables.

Results: The overall magnitude of anemia was 3.7%. Among anemic individuals, 84.2% and 15.8% of participants had mild and moderate anemia, respectively. The magnitude of stunting and thinness was 16.9% and 10.8%, respectively. Of them, 18.6% of stunting and 14.5% of thinness were severe. Of factors related to undernutrition, children from large families (≥5) were less likely to be stunted (AOR=0.38, 95% CI=0.2-0.7, P=0.002) compared to small families.

Conclusion: The magnitude of anemia in the study area was considered as an insignificant public health problem and none of the socio-demographic variables of participants were significantly associated with anemia and likewise with undernutrition except for family size. Further studies are required to clearly understand the impact of mass deworming on the magnitude of anemia and undernutrition.
