Does anyone know what the distinguishing features are between 1st, 2nd, 3rd and 4th degree tears are?

post #2 of 5
According to Varney's Midwifery 3rd ed.,

a first degree laceration involves the vaginal mucosa, posterior forchette and perineal skin.

a second degree tear involves the above and perineal muscles, any or all of the bulbocavernous, superficial transverse perineal, deep transverse perineal and pubococcygeus of the levator ani, also sulcus (more lateral) tears.

A third degree involves the above and the external anal sphincter (sometimes called a partial third degree laceration)

A fourth degree tear is one through the anal sphincter.

I understand that a 4th degree tear is sometimes called a completr 3rd drgree, but I have never seen it in practice. Is this info. for a class?

No, it's not for a class. I was just curious. I've tried looking on the internet and every site seems to be vague and says something different. Also, I have friend who wanted to know what 'degree' my tear was, and I had *NO* idea . Thanks again for the info!
