[Residual postoperative murmurs in children with congenital heart defects].

Fifty-four children without postoperative complications were admitted to the Department of Pediatrics, University Hospital Rebro, following a complete surgical correction of ventricular septal defect (VSD), atrial septal defect - secundum type (ASD II) and patent ductus arteriosus (PDA) in the period from June, 1989, to February, 1991. Twenty-two patients were treated surgically for VSD, 17 for ASD II and 15 for PDA. There were 23 male and 31 female children. In the early postoperative period, 57% of all the examinees had a murmur with the innocent or functional characteristics. The murmur was significantly more frequent among children with VSD than among children of other groups (ASD II, PDA). Sex, age and hematocrit did not influence this difference. There were 8 anemic children (3 with operated VSD, 4 with ASD II, and 1 with PDA). From this, it may be concluded that anemia also did not cause this difference. However, anemic children represented 50% of the examinees with a murmur among the operated for ASD II and 33% among those treated surgically for PDA. When these anemic children were eliminated, the others operated on for ASD II and PDA probably had the innocent murmurs, since the proportion of examinees with a murmur fits into the incidence of innocent murmurs in the population. The children operated for VSD have had a greater proportion of examinees with a murmur, and most likely, some of these murmurs do not belong to a group of innocent or functional murmurs. Their cause is unknown, as yet (probably, small organic lesion).(ABSTRACT TRUNCATED AT 250 WORDS)

[War injuries of the thorax].

Chest injuries are very common in war circumstances. Chest injury is commonly associated with other injuries of intrathoracic organs and development of shock, which has to be treated immediately. Our patients with war chest injuries are presented, along with our approach to the treatment of these injuries. "The conservative treatment" is stressed, with particularly importance of proper chest drainage, as a corner stone of proper and successful therapy. Shock treatment and prevention of atelectasis does present an unavoidable procedure of this type of therapy.

[Scanning electron microscopy analysis of peroperative injury at the junctions of the vasa vasorum and the collateral veins of venous autografts prepared for myocardial revascularization].

The authors' objective was to determine the peroperative changes in affluences of collateral veins and vasa vasorum of venous autografts prepared for a coronary bypass by standard and proposed methods. The investigations were carried out on dogs. In control group, the veins were prepared by the standard method where the vein is presented by several minor incisions with "skin bridges" planted in between. In the second group, the veins were prepared by the method developed by the authors, where the vein is presented by a long incision, maintaining perfusion with its own blood throughout surgery. The scanning electron microscope analysis has shown that the standard method of vein preparation causes significant damage in collateral veins and vasa vasorum affluences which are actually part of an internal surface of future venous autograft prepared for myocardium revascularization. The proposed surgical method considerably reduces possible peroperative damage of the vasa vasorum and collateral vein affluence sites forming a portion of the internal surface of the venous autograft. Therefore, based on the obtained results, this method is recommended for clinical application.

[Relation between the size of the left-right shunt and pulmonary resistance in congenital heart defects].

Relation between pulmonary vascular resistance (PVR) and left-to-right (L-D) shunt has been statistically tested in 87 patients with congenital heart diseases. In all patients, PVR and L-D shunt were calculated from the catheterization test results. Among 87 patients, 45 (52%) were female and 42 (48%) male children. The average age at the catheterization was 4.63 (min 6 mo, max 15 yr). Patients were divided into two groups with regard to the level of PVR. The first group consisted of patients with PVR higher than 160 dyn sec cm-5, and the second group with PVR lower than 160 dyn sec cm-5. The whole group was also divided according to VSD, and separate correlation was done for ASD with PVR below 160 dyn sec cm-5. A negative statistically significant correlation was observed between the height of PVR and size of L-D shunt among the entire group with PVR higher than 160 dyn sec cm-5, regardless of congenital heart disease (N = 29, r = -0.4676, P < 0.05). Also, a negative statistically significant correlation was found between PVR and L-D shunt in VSD, with PVR higher than 160 dyn sec cm-5 (N = 17, r = -0.669, P < 0.05). Among patients with low PVR, there was no negative statistically significant correlation between PVR and L-D shunt, neither for the whole group (N = 58, r = 0.1174, P > 0.05), nor among the patients with VSD r = -0.0133, P > 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

[Management of surgery patients with implanted cardiac pacemakers].

Patients having cardiac pacemaker implanted may be subjected to various general surgery procedures. Application of electrosurgery for the purpose of resection and coagulation, provides a high frequency electric field which produces electric voltage on the electrodes of the pacing system. This voltage may be detected within the pacing system, and various arrhythmias can be provoked in correlation with underlying rhythm and mode of pacing. Preoperative patient control and proper pacemaker programming can prevent the pacing malfunctions due to the electrosurgery application. Appropriate positioning of the neutral electrode in relation to the pacing system avoids the electric fields intersection and decreases their interference.
