Common sites for IM injections include the following: 1. The ventrogluteal muscle is the preferred site for adults and children over the age of 1 year because there are no large nerves or vessels, it is a large muscle, it is sealed by bone and contains less fat (Berman et al., 2008). 2.
electromyogram (EMG). Recording of electrical activity of a muscle associated with contraction and relaxation. This is obtained by placing a microelectrode within a muscle.The recording process is called electro-myography. diagnostic test that records the electrical activity of muscles. In the test, small electrodes are placed on or in the skin; the patterns of electrical activity are projected on a screen or over a loudspeaker. This procedure is used to test for muscle disorders, including muscular dystrophy. Mentioned in: Myopathies.
EEG provides a unique way of monitoring cerebral function in the intensive care unit (ICU) and it is useful both for recording short and long acting events. Typically, epileptic spikes may last for a fraction of seconds, but recordings for many hours, for example during sleep cycles may also give important information. Recordings lasting for many days may also be useful, to reflect slow trend changes in the EEG. One basic requirement for an EEG monitor in the ICU is that it has to present the original EEG on a monitor display, and also has to provide a paper printout.
