Q. 3

Which one of the following preservative is used while packing catgut suture?

 A

Isopropyl alcohol

 B

Colloidal iodine

 C

Glutaraldehyde

 D

Hydrogen peroxide

Ans. A

Explanation:

10% isopropyl alcohol is the routine packing fluid used in packing catgut sutures.

Catgut is available in glass tubes containing isopropyl alcohol and small quantity of water.

Catgut is prepared from the intestine of sheep.

Q. 4

Which of the following is a non absorbable suture?

Q. 4

Which of the following is a non absorbable suture?

 A

Polypropylene

 B

Vicryl

 C

Catgut

 D

Polydioxanone

Ans. A

Explanation:

Polypropylene or Prolene is a synthetic non-absorbable suture.

The advantages include minimal tissue reactivity and durability and the disadvantages include fragility, high plasticity, high expense, and difficulty of use compared to standard nylon sutures.

They are dyed blue, which helps in easy visibility against skin and when operating and is composed of a single filament.

Q. 5

B Lynch suture is applied on :

 A

Cervix

 B

Uterus

 C

Fallopian tube

 D

Ovaries

Q. 5

B Lynch suture is applied on :

 A

Cervix

 B

Uterus

 C

Fallopian tube

 D

Ovaries

Ans. B

Explanation:

Ans. is b i.e. Uterus

In case of massive haemorrhage if medical methods fail then either mechanical or surgical methods should be adopted.

Mechanical methods- include

  • Bimanual compression
  • Uterine packing under anesthesia
  • Balloon tamponade with a sengstaken tube inserted into the uterus.

Surgical methods

If Family is not completed                                      

If family is completed Application of B lynch sutures (COGDT 10/ed Pg 482, William Obs 23/e, p 776)

Radiographic embolization of pelvic vesels (COGDT 10/ed p 481)                                                    

Hysterectomy Uterine and ovarian artery ligation

–             Internal iliac artery ligation fail

Hysterectomy

Details of Surgical method.

  • B lynch Suture/ Brace suture is an alternative to vessel ligation technique in the surgical management of PPH. It involves the use of vertical brace sutures, which appose the anterior and posterior walls of the uterus, which leads to compression of the fundus and the lower uterine segment, thereby controlling the hemorrhage.
  • The main advantage is that it is very easy to perform and may obviate the need for a hysterectomy.

It is commonly performed at cesarean section but can also be done after vaginal delivery.

Application of block sutures : The anterior and posterior uterine walls are approximated until no space is left in uterine cavity using block sutures I multiple squares.

Uterine and ovarian artery ligation : It is easier than internal iliac artery ligation and can be tried as the first resort .

Internal iliac artery ligation (anterior division) : It should be considered before hysterectomy, especially in nullipara. as the uterus can be preserved.

The artery is ligated about 3 cm from common iliac artery. It will ensure that posterior division is not included in the ligature, as it may lead to loss of lower limb sensation (femoral artery and dorsalis pedis artery are branches of posterior division.

Arterial embolisation : Done when patient is hemodynamically stable and good radiological facilities are available. Under fluoroscopic guidance femoral artery is catheterised, the bleeding vessel identified and embolisation is carried out using gel foam.

Hysterectomy : It is the most definative method of controlling PPH and should be the last resort.
