Methods of Induction of Labor

Different methods of induction of labour are:

Membrane Sweeping

This method is only performed at term and placenta previa is ruled out prior to the procedure. After cervix begins to dilate, a gloved finger is inserted through the cervix and is rotated around the inner rim of cervix. In this method chorionic membrane is stripped off from underlying decidua which causes release of natural prostaglandins.

Prostaglandin

Prostaglandin is available in form of gel, pessary, or tablet. PG E2 is the most common formulation. It can be inserted vaginally into the cervix to ripen cervix and initiate contractions.

Artificial rupture of membranes

Prostaglandin alone may not be sufficient for a successful induction of labour especially in primiparous women. In cases Artificial rupture of Membranes and Oxytocin are used.

Oxytocin

Oxytocin can be used after rupture of membranes. It is given in IV infusion as dilute solution.

3-5 contractions every 10 minutes is desirable. For this infusion is started at a low rate and small increments are made every 30 minutes till the desired contractions are achieved.

If there are >5 contractions every 10 minutes then the oxytocin should be stopped and if necessary a tocolytic drug subcutaneous terbutaline is administered.

Mifepristone and Misoprostol

This drug combination is used for induction of labour only in cases of Intrauterine fetal death.

Different types of Heart Murmurs with Sound

ⒸPathologynuggets. Notes to review for medical students, residents, and doctors Hello! welcome to our new blog post on cardiac murmurs. In this blog post about heart murmurs, we review the most common types of heart murmurs. Murmur is the sound of blood flowing abnormally through the heart valves and most often signs of valve disorders. If you are new to the blog, don't forget to show your support by like and subscribe. Read till the end of the blog for some bonus tips! Now let's continue our review. Normal heart sounds consist of sounds S1 and S2. S1 represents closure of mitral valve and tricuspid valves at the beginning of systole. S2 represents the closure of aortic and pulmonic valves at beginning of diastole. Thus, the interval between s1 and s2 represents systole, and in this interval systolic murmurs are heard Similarly, diastolic murmurs are heard at the interval between s2 and s1. So, what are the most common types of heart murmurs? For easy understanding, we can di...

Approach to Types of Vasculitis -- Easy review notes of Large, Medium, Small vessel and other Vasculitides

ⒸPathologynuggets. Notes to review for medical students, residents, and doctors. Vasculitides are autoimmuine disorders characterized by inflammation of blood vessels. Most of them are chronic systemic disorders that affect the multiple systems and should be considered in differential diagnoses of any multisystem illness. Vasculitis can be divided into large vessel, medium vessel or small vessel vasculitis based on the size of the vessels involved. Large Vessel Vasculitis ‌Giant cell arterities or Temporal arteritis Takayasu arterities Medium Vessel Vasculitis ‌Polyarterities Nodosa Kawasaki Disease Small Vessel Vasculitis ‌Granulomatosis with Polyangitis(GPA) ‌Microscopic polyangitis (MPA) ‌Eosinophilic Granulomatosis with Polyangitis (EGPA) ** Small vessel vasculitides GPA, MPA and EGPA are also known as ANCA ...

Heart Rate Calculation : ECG interpretation quick review

pathologynuggets.blogspot.com 2023 ECG interpretation is an important skill for any healthcare professional. How to calculate the Heart rate? Several methods can be employed to ascertain the heart rate. One straightforward and expedient approach involves Identifying a QRS complex aligned with a prominent vertical grid line. followed by counting the number of large squares to the subsequent QRS complex. Dividing 300 by this count provides the heart rate. Example: In the presented ECG, there are 2 large squares between QRS complexes, resulting in a calculated heart rate of 150 beats per minute. Note: This method only works if the paper speed is set to standard i.e. 25mm/second. At the standard speed of 25mm/s, each large square = 0.2 second each small square = 0.04 second Similarly, this method only works if the heart rhythm is regular. You can find how to assess heart rhythm and calculate heart rate for abnormal rhythm in this ar...
