Antibiotic treatment lowers the risk of embolic complications in people with infective endocarditis.In acute endocarditis, due to the fulminant inflammation, empirical antibiotic therapy is started immediately after the blood has been drawn for culture to clarify the bacterial organisms responsible for the infection. This usually includes vancomycin and ceftriaxone IV infusions until the infecting organism is identified and the susceptibility report with the minimum inhibitory concentration becomes available. Once this information is available, this allows the supervising healthcare professional to modify the antimicrobial therapy to target the specific infecting microorganism. The routine use of gentamicin to treat endocarditis has fallen out of favor due to the lack of evidence to support its use (except in infections caused by Enterococcus and nutritionally variant streptococci) and the high rate of complications. In cases of subacute endocarditis, where the persons hemodynamic status is usually stable, antibiotic treatment can be delayed until the causative microorganism can be identified.Viridans group streptococci and Streptococcus bovis are usually highly susceptible to penicillin and can be treated with penicillin or ceftriaxone. Relatively resistant strains of viridans group streptococci and Streptococcus bovis are treated with penicillin or ceftriaxone along with a shorter two-week course of an aminoglycoside during the initial phase of treatment.
Electrocardiography (ECG), in which electrodes are used to record the electrical activity of the heart, is not particularly helpful as no specific rhythms or ECG patterns can be used to detect PDA.A chest X-ray may be taken, which reveals overall heart size (as a reflection of the combined mass of the cardiac chambers) and the appearance of blood flow to the lungs. A small PDA most often accompanies a normal-sized heart and normal blood flow to the lungs. A large PDA generally accompanies an enlarged cardiac silhouette and increased blood flow to the lungs. Prevention
Some evidence suggests that intravenous NSAIDs, such as indomethacin, administration on the first day of life to all preterm infants reduces the risk of developing a PDA and the complications associated with PDA. Intravenous Indomethacin treatment in premature infants also may reduce the need for surgical intervention. Administering ibuprofen probably helps to prevent PDA and reduce the need for surgery but it also likely increases the risk of kidney complications. Treatment
Symptomatic PDA can be treated with both surgical and non-surgical methods. Conservative
Neonates without adverse symptoms may simply be monitored as outpatients. Surgery
Surgically, the DA may be closed by ligation (though support in premature infants is mixed). This can either be performed manually and be tied shut, or with intravascular coils or plugs that leads to formation of a thrombus in the DA.Devices developed by Franz Freudenthal block the blood vessel with woven structures of nitinol wire.Newer procedures performed effectively in older, bigger children include catheter PDA occlusion and video-assisted thoracoscopic PDA clipping.
