Intramuscular injection, often abbreviated IM, is the injection of a substance into a muscle. In medicine , it is one of several methods for parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than ...
Intraosseous infusion, pediatric. A comparison of intravenous (IV), intramuscular (IM), and intraosseous (IO) routes of administration concluded that the intraosseous (IO) route is the preferred method versus intramuscular (IM) and comparable to intravenous (IV) administration in delivering pediatric anaesthetic drugs.

A little larger is the BCG tuberculosis vaccine, which is 0.05ml for babies and children under 12, and 0.1ml for others. This tiny dose is inserted a couple of millimetres under the skin, producing a small blanched blister. [8] Many vaccines for intramuscular injection have 0.5ml liquid, though a few have 1ml. [a]
The term injection encompasses intravenous (IV), intramuscular (IM), subcutaneous (SC) and intradermal (ID) administration. [35] Parenteral administration generally acts more rapidly than topical or enteral administration, with onset of action often occurring in 15–30 seconds for IV, 10–20 minutes for IM and 15–30 minutes for SC.

DTaP and DT are given to children less than seven years old, while Tdap and Td are given to those seven years old and older. [7] [8] The lowercase d and p denote lower strengths of diphtheria and pertussis vaccines. [7] Tetanus antiserum was developed in 1890, with its protective effects lasting a few weeks.
A hexavalent vaccine, or 6-in-1 vaccine, is a combination vaccine with six individual vaccines conjugated into one, intended to protect people from multiple diseases. [1] [9] The term usually refers to the children's vaccine that protects against diphtheria, tetanus, pertussis, poliomyelitis, haemophilus B, and hepatitis B, [1] [9] which is used in more than 90 countries around the world ...
In 2016, the CDC reported that 80.4% of children in the US have received four or more DTaP vaccinations by 2 years of life. [20] Vaccination rates for children aged 13–17 with one or more TDaP shots was 90.2% in 2019. [20] Only 43.6% of adults (older than 18) have received a TDaP shot in the last 10 years. [20]
The intravascular volume is low because the water will move through a process called osmosis out of the vasculature into the cells (intracellularly). The danger is tissue swelling (edema) the most important being brain edema which in turn will cause more vomiting.
