Kiwi Omni Cup Vacuum Delivery | Dr. Aditya Nimbkar

[00:00:00]Hi everyone. So today I've with me a very interesting instrument and that is Kiwi Omni Cup.

[00:00:05]Kiwi Omni Cup is a form of ventouse or vacuum delivery that we use. And by the way, Omni Cup is a trademark name of the company. This has various parts to it.

[00:00:12]This is the pressure gauge wherein I'll be measuring the pressure of the vacuum that is created. This is the pump mechanism. This is a tubing that transmits the pressure. It has a distance that is marked to tell me how inside deep inside is my cup. Then I have my actual cup which contains a foam filter to prevent the contamination of this pump by passage of any dirt through it and also distributes the vacuum or the pressure evenly.

[00:00:34]On this gauge you can see that there are various units that are given. So if I'm going to talk about in terms of kg per cm squared it is going to be between the ideal vacuum that I have to create is between 0.6 to 0.8. In terms of kilopascal it is going to be between 60 to 80. And the commonest unit that I use is going to be millimeter of mercury. So it should be between 500 and 600 ideally. How to use it? So this has to be attached to the flexion point of the fetal head. And of course once all the prerequisites have been fulfilled, once that is done, I'll be starting to increase the vacuum. You can see that when I'm increasing the vacuum this thing is going inside. And once it reaches that exact point, the green mark. Now given that I'm doing it on a sofa it may not reach there.

[00:01:15]Then I'm going to pull the fetus out.

[00:01:17]The fetus is going to be pulled out along the pelvic curve. And once the fetus is delivered, there is this button over here which shows vacuum release. It will release the vacuum and it will come off. You can see that this is created.

[00:01:28]Now this on the fetal head is going to be called as a chignon or a chignon which is basically a swelling that is created on the flexion point which is pulled by this Kiwi Cup.

[00:01:37]Not too many complications. You have to remember that if you have two pop offs or you have tried to pull three times but the head has not descended down. Or if you have wasted or spent more than 20 minutes doing this and it has not worked then you have to switch to some alternative method of delivery. Most preferably cesarean section because using sequential forceps is not a good thing, not good practice. Complications not too many. Cephalhematoma especially if a fetus is anti-coagulated or has some coagulation disorder. And occasionally, given that this is a hard cup, we even get the soft cups. This can lead to cookie cutter injuries. Basically, scalp laceration can happen, but not that common given that this pressure is going to be maintained by me. So, a very good instrument and a very uh handy instrument that is often found in a lot of uh labor rooms. Kiwi OmniCup.
