Percussion sounds over bladder

  1. 0
    Hey everyone!

    What are the percussion sounds over urinary retention?
    What are normal percussion sounds of the bladder?
    Our instructor said that it is tympany over urinary retention but I couldn't find it anywhere to clarify.
    Thanks

    um, why would you want to percuss a bladder? i have never percussed a bladder. you can palpate it and learn what you need to learn, which is-- is it too full? how much? midline?

    you percuss something to tell whether it's dense when it shouldn't be (like a lung full of mucus that's atelectatic / consolidated) or full of air when it shouldn't be (like a belly with a bowel obstruction) or fluid (like a belly full of ascites-- look for the fluid wave). or if it's painful (like when you percuss over the kidneys when you want to find out if there is an infection in there.)

    ::confused by this question::

    it is unusual to use the assessment technique of percussion of the bladder these days with bladder scanners. the assessment skill of percussion was the way to determine the fullness of the bladder. think of the bladder as a ballon. when the balloon is empty and you tap on it there is no real sound....right? now fill that balloon with water and flick your finger on the side....what do you hear????

    percussion is an assessment technique which produces sounds by the examiner tapping on the patient's chest wall. just as lightly tapping on a container with your hands produces various sounds, so tapping on the chest wall produces sounds based on the amount of air in the lungs. percussion sets the chest wall and underlying tissues into motion, producing audible sounds and palpable vibrations. percussion helps to determine whether the underlying tissues are filled with air, fluid, or solid material.

    percussing the anterior chest is most easily done with the patient lying supine; the patient should sit when percussing the posterior chest. place the first part of the middle finger of your nondominant hand firmly on the patient's skin. then, strike the finger placed on the patient's skin with the end of the middle finger of your dominant hand. .

    work from the top part of the chest downward, comparing sounds heard on both the right and left sides of the chest. visualize the structures underneath as you proceed.

    the following diagram that shows percussion notes on the posterior chest:

    resonant sounds are low pitched, hollow sounds heard over normal lung tissue. flat or extremely dull sounds are normally heard over solid areas such as bones. dull or thudlike sounds are normally heard over dense areas such as the heart or liver. dullness replaces resonance when fluid or solid tissue replaces air-containing lung tissues, such as occurs with pneumonia, pleural effusions, or tumors. hyperresonant sounds that are louder and lower pitched than resonant sounds are normally heard when percussing the chests of children and very thin adults. hyperresonant sounds may also be heard when percussing lungs hyperinflated with air, such as may occur in patients with copd, or patients having an acute asthmatic attack. an area of hyperresonance on one side of the chest may indicate a pneumothorax. tympanic sounds are hollow, high, drumlike sounds. tympany is normally heard over the stomach, but is not a normal chest sound. tympanic sounds heard over the chest indicate excessive air in the chest, such as may occur with pneumothorax. tympanic sounds over the bladder indicates a full bladder.
