Exercise 1 – Finding Full-Text

• Access the PDF of the following article:

Thoresen M, Hellström-Westas L, Liu X, de Vries LS. Effect of hypothermia on amplitude-integrated electroencephalogram in infants with asphyxia. Pediatrics. 2010 Jul;126(1):e131-9. Epub 2010 Jun 21. PubMed PMID: 20566612.

Introduction to PubMed

How do I find the recent

literature on my topic?!?

Define the Search Topic

• Define your search topic in a single question or statement.

Is hypothermia effective for treating neonatal asphyxia?

Is dobutamine or dopamine more effective for treating hypotension in the neonate?

Analyse the Search Topic

Analyse your search topic:

• What are the primary concepts (2-3)?Is hypothermia effective for treating neonatal asphyxia?

• What are the limiters ?– Population (Newborn infants, birth – 1 month)– Publication type (i.e. RCT, Review)– Publication date (i.e. last 10 years)

Basic Searching in PubMed

• Search your primary concepts, separating each concept with AND.

• Click “Search”.

Combine Different Concepts Using AND

AND

• Combine different concepts

• Finds articles where both concepts are present.

Applying Limits

• Click the limits link to see the complete list of options.

1. Check the appropriate limits for your search.

2. Click “Search”.

Commonly used limits include:

• Type of Article

• Language

• Ages

• Publication Date

Exercise 2: Basic Searching

After morning rounds, a NICU fellow is wondering if there

are any recent articles on the use of probiotics for

preventing necrotizing enterocolitis in the newborn.

Search Strategy:

probiotics AND necrotizing enterocolitis

Exercise 3: Basic Searching

For a research project, you would like to find published RCTs on

whether dopamine or dobutamine is more effective for

treating hypotension in the neonate from the last 20 years.

Search Strategy:

dopamine AND dobutamine AND hypotension

Managing Search Results

Clinical Queries in PubMed

Exercise 4: Clinical Queries in PubMed

Use clinical queries to determine the role of lumbar puncture in determining sepsis in neonates.

Clinical Queries Strategy:

Lumbar puncture sepsis neonate

Diagnosis

Broad

Exercise 5: Clinical Queries in PubMed

Use clinical queries to find articles that discuss acceptable levels of oxygen to prevent retinopathy of prematurity.

Clinical Queries Strategy:

Oxygen levels retinopathy of prematurity

Etiology

Broad

Exercise 6 – Clinical Query
