Accurate placement of central venous catheters in pediatric patients using endocavitary electrocardiography: reassessment of a personal technique.
Full text linkTo avoid the need for radiological control in the assessment of the proper location of central venous catheters (CVC), a particular use of endocavitary electrocardiography (EC-ECG) was proposed 10 years ago. The aim of this study is to reassess our experience with this method. EC-ECG assumes that the CVC, when filled with normosaline and connected to a standard electrocardiograph, behaves like an exploring electrode. The approach of the catheter tip to the right atrium is then detected by a slightly increasing negative P wave. When the tip reaches the exact level of the sinus node, the P wave suddenly deepens. After a preliminary test of the reliability of the technique versus the standard method in 50 CVC placements verified by both EC-ECG and chest x-ray, we have placed 807 CVCs in children using EC-ECG only. There have been no false-positive and one false-negative test result (lead connector misplacement). In 17 cases in which intrinsic deflection was not detected, the catheter tip was found to be wrongly positioned; all the remainder CVCs have been successfully positioned. For 10 years this technique has proved to be a simple, safe, quick, inexpensive and highly reliable method to assess the correct positioning of the CVC
Conservative surgery of bladder-prostate rhabdomyosarcoma in children: results after long-term follow-up.
No full textBetween 1968 and 1982, 10 children (7 boys and 3 girls) with a mean age of 3.2 years affected by bladder (8 cases) and prostate (2 cases) rhabdomyosarcoma (RMS)-ali histologi¬cally embryonal-were seen. Three (1 with bone metastases at diagnosis and 2 with stage III tumor) underwent radica) surgery; ali died because of progression of the disease. Seven children were treated with conservative surgery: 3 solid type bladder tumors were removed together with a narrow strip of apparently healthy bladder wall, sparing 30 to 70% of the bladder; 3 botryoid type bladder tumors were removed bluntly and implantation sites fulgurated; in 1 prostate tumor osmotic cytolysis of the neoplastic mass was achieved with multiple injections of hypertonic saline solu¬tion (NaCI 30%). Surgery was followed by chemotherapy with a vincristine actinomycin D and cyclophosphamide protocol and radiotherapy (20 to 39.5 Gy). Six of the seven are alive and disease free with a norma) functional bladder alter 10 to 21 years. The validity of a primary conservative surgical approach with preservation of the bladder, followed by adjuvant therapy, is emphasized
Late recurrence of infantile hypertrophic pyloric stenosis
No full textA case of infantile hypertrophic pyloric stenosis that recurred 2 months after Ramstedt's operation is presented. A second pyloromyotomy was carried out with resolution of symptoms. A computer-based review of the literature suggests that this is the first such report. © 1994 Springer-Verlag
