The MeSH Browser retrieves MeSH vocabulary records (MeSH Descriptors, Publication Types, Qualifiers, and Supplemental Concepts) from the MeSH vocabulary when they partially or exactly match a MeSH Browser query of 200 characters or less.
MeSH, or Medical Subject Headings, allow a searcher to quickly identify articles of interest.
MeSH is the National Library of Medicine’s (NLM’s) controlled vocabulary or subject heading list. It’s used by indexers, who are subject analysts, and maintain the PubMed database, to reflect subject content of journal articles as they are published.
Q: How many entry terms are in the MeSH vocabulary? A: In 2016 MeSH there are 681,505 Entry terms (ETs), including ETs for Descriptors, Subheadings, Publication Types and Supplementary Concepts.
Since MeSH terms are assigned by librarians who look at the full text of an article, they capture the semantic content of an article that cannot easily be captured by keyword or phrase searches. Thus assigning MeSH terms to articles is a routine task for the indexing staff at NLM.
CINAHL uses the (U.S.) National Library of Medicine’s Medical Subject Headings (MeSH). These subject headings are arranged in a hierarchy that enables searching at various levels of detail, from general to very specific terms.
The Medical Subject Headings (MeSH) thesaurus is a controlled and hierarchically-organized vocabulary produced by the National Library of Medicine. It is used for indexing, cataloging, and searching of biomedical and health-related information.
® The National Library of Medicine’s (NLM) Medical Subject Headings (MeSH) is the controlled vocabulary used for indexing PubMed (PubMed.gov) citations. MeSH provides a consistent way to retrieve information where different terms are used by authors for the same concept.

What is MeSH? MeSH is the US National Library of Medicine(NLM)’s controlled vocabulary or thesaurus of terms used to organise the MEDLINE database. It is also used for searching in PubMed, and some other databases, such as CINAHL, and the Cochrane Library.
The Ovid search interface has a feature to help you find the proper MeSH term. On the main search screen be sure to check the box next to “Map Term to Subject Heading” – this tells the database to provide you with a list of choices of standardized MeSH terms that are associated with your topic.
Using the Medical Subject Headings (MeSH) is efficient because they search for matching content rather than text. Ovid’s mapping is designed to suggest MeSH for your concept. Simply type in a word or phrase into Ovid’s Advanced Search and make sure that Map Term to Subject Heading is enabled.

MEDLINE (Medical Literature Analysis and Retrieval System Online, or MEDLARS Online) is a bibliographic database of life sciences and biomedical information. It includes bibliographic information for articles from academic journals covering medicine, nursing, pharmacy, dentistry, veterinary medicine, and health care.
Midlines are usually put into a vein in the arm. … It is put into a large vein in the arm and ends in a large vein near the heart. Sometimes a leg vein is used for infants. A PICC can be used for longer periods of time than a midline.
A PICC line is a longer catheter that’s also placed in the upper arm. Its tip ends in the largest vein of the body, which is why it’s considered a central line. PICC stands for “peripherally inserted central–line catheter.” A CVC is identical to a PICC line, except it’s placed in the chest or neck.
PICC lines are placed into a vein in your arm, and then guided into a larger vein in your chest. A midline catheter is put into a vein by the bend in your elbow or your upper arm. The midline catheter tube is shorter than a PICC line. The midline tube ends in a vein below your armpit.
8. The midline catheter is made of extremely soft material and is not recommended for routine blood draws. However, it is possible to draw blood samples without collapsing the catheter if slow, gentle pressure is used.
This study demonstrates that midline catheters are a safe alternative to CVCs, for the safe and efficacious administration of vasopressors for prolonged periods of time.
These catheters are called “midline catheters” when they are placed in a way that the tip of the catheter remains in a relatively large vein, but doesn’t extend into the largest central vein. … The skin exit point of a non-tunneled central catheter is in close proximity to the entry point of the vein used.
A peripherally inserted central catheter, also known as a PICC line, is the most common type of non-tunneled central venous catheter. This line is most often placed in the arm.
A patient can be a difficult stick for any number of reasons, like dehydration, a history of intravenous drug use, or obesity. Underweight and premature infants are particularly difficult candidates for normal peripheral IV access because their veins are simply so small.
Intravenous (IV) cannulation is a technique in which a cannula is placed inside a vein to provide venous access. Venous access allows sampling of blood, as well as administration of fluids, medications, parenteral nutrition, chemotherapy, and blood products.
The 4 Main Types of IV Fluids
Tips and Tricks for Accessing Problem Veins
The common reasons to discontinue IV fluids are: the patient’s fluid volume has returned to baseline; the patient is being discharged from the facility; the IV catheter needs to be replaced; or the IV site has become unfavorable due to infection, infiltration, extravasation, or phlebitis.
The fluids and medications are administered through this tube. Once the tube has been placed, the IV site shouldn’t hurt, sting, or burn. When the IV procedure is completed, some swelling and bruising at the site are common and not cause for concern. Most IV sites heal quickly in a few days.
A small IV tube is left in the arm or leg when the needle is removed so the fluid can get into the vein. There should be little or no pain after the needle is removed.
