Removal of infected dual chambered transvenous pacemaker and implantation of a new epicardial dual chambered device with cardiopulmonary bypass: experience with seven cases.

Seven patients with infected transvenous dual chambered pacemakers have undergone removal of the device using cardiopulmonary bypass. There were four women and three men with a mean age of 58 years. Six patients had localized infection in the generator pocket (mean of 4.6 previous unsuccessful operations for surgical sterilization). Four infections were due to Staphylococcus epidermidis, two to Staphylococcus aureus, and one patient presented septicemia caused by Staphylococcus epidermidis and Pseudomonas aeruginosa. The atrial and ventricular transvenous electrodes were removed under direct vision using cardiopulmonary bypass. A new dual chambered epicardial pacemaker was implanted. The procedure was well-tolerated, and all patients are infection free with working pacemakers after a mean follow-up of 25.4 months.

Computerized information system for ICU patient management.

To solve the problem of data management, a digital computer was introduced in this ICU in 1977. Data are manually entered at the bedside alpha-numeric keyboards; two beds are directly connected to the computer. The system was especially designed to work in the 11-bed ICU; its functions are: (1) admission, discharge, and transfer data of patients; (2) management of doctors' and nurses' notes in a free text form; (3) management of the problem-oriented record; (4) management of physical and bio chemical variables, medical disorders, and fluid balance; and (5) diagnostic and therapeutic decision-making. Since 1977, the authors have computerized over 2600 patients and now conclude: (1) data management and communication have improved, thus, allowing nurses more time for direct patient care; (2) teaching of the residents and nurses has been facilitated and minimizes disparities from their diverse experience; (3) it has contributed to the development of protocols for many of the procedures; and (4) it has led to a more systematic approach to patient care. The assistance of a professional computer programmer and continuous maintenance of the software are essential.

[Pediatric intensive care (author's transl)].

In the Intensive Care Unit of our General Hospital, where an important obstetric-pediatric unit exists, 392 infants have been treated from August 1974 to 1976. Although the results of all age groups are shown, the neonatal one is specially considered. All those patients who recovered and were discharged from the hospital were called for revision and the results of those whom attended are shown. The convinience of the regionalisation and hierarchisation of these intensive care units and the necessity of adequately organise the communication and transport of these patients from the peripheral small units to the regional one, is emphasized.

[Decanulation of tracheostomised children (author's transl)].

It is described eight tracheostomised patients, advising an early and gradual tracheal decanulation using silver tracheostomy tube with a window in the posterior curvature (fenestrated tube, Alder Hey pattern) and proper sedation at the moment of definitive decanulation. Decanulation techniques and the mechanical and functional difficulties that can occur and how to avoid them are described: Finally the tracheostomy tubes that have been used are mentioned.

[Intermittent mandatory ventilation (author's transl)].

Intermittent mechanical ventilation is a frequent form of therapy for respiratory failure in children. Due to its difficult application in patients with high respiratory rate and difficult synchronization with the respirator, intermittent mandatory ventilation (I.M.V.) was tried on these patients, introducing a unidirectional valve, connected to a continuous flow of gases, on the inspiratory side of the respirator. With I.M.V. the patient is able to breath spontaneously the gases coming from the unidirectional valve and at the same time the respirator provides periodical insuflations at a frequency previously determined by us. The pressure generated by the respirator in the respiratory circuit, closes the unidirectional valve sending gases to patient. This technique not only reduced time of application of mechanical ventilation but made weaning shorter, easier and safer.
