Repair of ventricular sepal defect

This photograph shows the surgical repair of a traumatic ventricular septal defect (VSD). A VSD is a hole between the right and left ventricles of the heart and is usually seen as a congenital condition, known as a ‘hole in the heart’. A traumatic VSD, as seen in this case, is a rare complication of chest injury. It might manifest immediately after trauma, leading to heart failure and an inability to stabilise a patient, or it might be delayed and detected months later. Traumatic VSDs can be treated in a variety of ways, depending on the effect they have on the patient. Treatment options range from monitoring and a conservative approach to open surgery, as is depicted here. In this image, the VSD is seen at the bottom, and a bovine patch is being parachuted and stitched into place to seal the defect.

AVRT (Atrioventricular reentrant tachycardia)

seen in patients with WPW syndrome.

electrical impulse make a circuit, which consists of an anterograde limb(normal pathway) and a retrograde limb(accessory pathway).

impulse start from atrium → AV node(anterograde) → His-Purkinje → ventricle → accesory pathway(retrograde)　→ back to atrium

1. narrow QRS regular tachycardia
2. negative P waves seen after QRS complex.
3. no delta wave, since antegrade conduction is not occurring via the accessory pathway 

Tx.

1. Valsalva maneuver 
2. Adenosine i.v.
3. Ca channel blockers (verapamil or diltiazem)

Wow I’ve never seen adenosine convert a rhythm that quickly. Every time I’ve given it, the asystolic phase lasts seconds! Probably one of my favorite drugs to administer.

Only one way to get one of those……

Can you spot the fracture?

The radically simple Uniject™ injection system

Rethinking the needle to extend the reach of lifesaving vaccines and medications

What if syringes were so easy to use that even untrained health workers could give injections without the risk of error?

What if vaccines for developing countries could be prepackaged in low-cost prefilled syringes, vastly reducing the amount of vaccine wasted?

What if syringes could not be reused—and we knew for certain that gateway to HIV transmission was closed?

The Uniject™ autodisable injection system (Uniject), born in PATH’s Seattle shop, is little more than a small bubble of plastic attached to a needle, but it answers all these needs. It is so simple that health workers can learn to use it after less than two hours of training. It cannot be reused, which eliminates one route of disease transmission. And it is precisely prefilled by the pharmaceutical producers with a single dose, which ensures that the correct amount of drug is delivered and that none is discarded unnecessarily.

PATH developed Uniject with funding from the US Agency for International Development and then licensed the system to BD, the largest syringe manufacturer in the world. As part of the licensing agreement, BD supplies the Uniject system to pharmaceutical producers at preferential prices for use in developing-country programs. Developing Uniject and bringing it to market has been a 20-year endeavor.

Originally developed for use with vaccines, Uniject now promises to extend the reach of other lifesaving drugs as well as contraception.

Uniject is a trademark of BD.
