Triads of Abortion

THREATENED ABORTION:
*1st trimester bleed
*Sono: Norm. pregnancy
*Internal os CLOSED
---Management: conservative


MISSED ABORTION
*1st trimester bleed
*Sono: NON-viable pregnancy
*Internal os CLOSED
---Manage: D&C and conservative


INEVITABLE ABORTION
*1st trimester bleed
*NO POC passed vaginally
*Internal os DILATED
---Manage: EMERGENCY D&C


INCOMPLETE ABORTION
*1st trimester bleed
*Retained POC, but SOME POC PASSED
*Internal os DILATED
---Manage: EMERGENCY D&C


COMPLETE ABORTION
*1st trimester bleed
*NO POC RETAINED
*Internal os CLOSED
(Note: cervical os closes after all POC are expelled)
--->Thanks again to Aashi for correcting this one.
---Manage: Observe and serial B-hCG

Good work Dr.Virgo..but i do have few suggestions to make:-

Abruptio Placenta Triad:
*MCC of Late trimester PAINFUL bleeding
*Normal placental implantation
*+ /- DIC

COMPLETE ABORTION
*1st trimester bleed
*NO POC RETAINED
*Internal os IS 'CLOSED' (Kaplan has a typo here..u may cross-chk this in williams obs or emedicine http://www.emedicine.com/med/topic3310.htm )
---Manage: Observe and serial B-hCG


Mg Toxicity Triad

*Preterm labor tocolysis
( this is not a sign of toxicity, it is one of the benefits of Mg in preterm labor)

So the triad is :-

* Disappearence of DTR( pateller reflex diminshed is the first sign at levels < or = to 10meq/l of Mg) and muscle weakness

*Pulmonary edema

*Resp depression at levels > 10 meq/l and resp.arrest at levels > 12 meq/l of Mg.

Absolutely RIGHT. smiling face
Thanks for adding that detail... Actually this is another way we can differentiate Abruptio Placenta from Placenta Previa or Vasa Previa...Although all cause LATE trimester bleeding,
AP will cause PAINFUL bleeding whereas PP and VP will cause painless bleeding... Good point.

COMPLETE ABORTION
*1st trimester bleed
*NO POC RETAINED
*Internal os IS 'CLOSED' (Kaplan has a typo here..u may cross-chk this in williams obs or emedicine http://www.emedicine.com/med/topic3310.htm )

Regarding the different types of abortions, they represent findings along a continum from the beginning of losing the pregnancy to complete expulsion of the products of conception.

Complete Abortion is the FINAL one... In this one there are NO Products of Conception retained (we agree on that)... And so therefore, the cervical os must be DILATED (how else would the products of conception be expelled otherwise?)... I understand it says CLOSED in emedicine, and I have read dilated vs. closed from other sources as well... I think it may depend on how long after the abortion occured. If you check it immediately afterwards, it is probably open (dilated), but if the woman comes in a few days or weeks afterwards, it will be closed by then.
See this site:
http://www.merck.com/mmpe/sec18/ch263/ch263l.html
Go to table 2 which says for Complete Abortion cervical os can be either DILATED OR CLOSED.

Just my thoughts... Let me know what you think... And thanks again for bringing up this point.

You are right: Mg is used to prevent pre-term labor, so that's not a toxicity effect... I'll change it in the original post for everyone.
Where did you read about the effect of Mg on DTR's? And why is it at levels LESS THAN 10? Did you mean more than 10???
I would like to read more about that. Thanks. smiling face


  #15

Abt Mg TOXICITY--> the therapeutic level of Mg is b/w 4- 7 mEq/l anythin more that ( Say 9- 10 meq/l) effects the DTR FIRST specially the patellar, so u have to monitor the reflexes in a pt who is on Mg , the rest of s/s depends on the level of Mg In the blood , which i had mentioned above..
And the source to the above info is WILLIAMS OBSTETRICS( 21st edition)
