METHODS: All consecutive inborn infants with umbilical arterial (UAC) and/or umbilical venous catheters (UVC) inserted for more than 6 h duration were included in the study. Each infant was screened for thrombosis in the abdominal aorta and inferior vena cava by 2-D abdominal ultrasonography within 48-72 h of insertion of umbilical vascular catheters. Subsequent serial scanning was performed at intervals of every 5-7 days, and within 48 h after removal of catheters.
RESULTS: Upon removal of umbilical catheters, abdominal aortic thrombi were detected in 32/99 (32.3%) infants with UAC. Small thrombi were detected in the inferior vena cava of 2/49 (4.1%) infants with UVC (one of whom had both UAC and UVC). When compared with those who received only UVC (n = 18), infants who received either UAC alone (n = 68) or both UAC and UVC (n = 31) had significantly higher risk of developing thrombosis (odds ratio (OR): 7.6, 95% confidence interval (CI): 1.1, 325.5)). Logistic regression analysis of various potential risk factors showed that the only significant risk factor associated with the development of abdominal aortic thrombosis following insertion of UAC was longer duration of UAC in situ (for every additional day of UAC in situ, adjusted OR of developing thrombosis was: 1.2, 95% CI: 1.1, 1.3; P = 0.002).
CONCLUSION: Umbilical arterial catheter-associated thrombosis was common. Umbilical arterial catheter should be removed as soon as possible when not needed. Upon removal of UAC, all infants should be screened for abdominal aortic thrombus by 2-D ultrasonography.
METHODS: A randomized controlled study was carried out in the neonatal intensive care unit (NICU) of Hospital Universiti Kebangsaan Malaysia over a 12-month period. Fifty-four healthy term infants with severe hyperbilirubinemia were randomized to receive either solely enteral feeds (n = 27) or both enteral and intravenous (n = 27) fluid during phototherapy.
RESULTS: There were no significant differences in the mean birthweight, mean gestational age, ethnic distribution, gender distribution, modes of delivery and types of feeding between the two groups. Similarly, there was no significant difference in the mean indirect serum bilirubin (iSB) level at the time of admission to the NICU between the enteral (359 +/- 69 micromol/L [mean +/- SD]) and intravenous group (372 +/- 59 micromol/L; P = 0.4). The mean rates of decrease in iSB during the first 4 h of phototherapy were also not significantly different between the enteral group (10.4 +/- 4.9 micromol/L per h) and intravenous group (11.2 +/- 7.4 micromol/L per h; P = 0.6). There was no significant difference in the proportion of infants requiring exchange transfusion (P = 0.3) nor in the median duration of hospitalization (P = 0.7) between the two groups. No infant developed vomiting or abdominal distension during the study period.
CONCLUSION: Severely jaundiced healthy term infants had similar rates of decrease in iSB levels during the first 4 h of intensive phototherapy, irrespective of whether they received oral or intravenous fluid supplementation. However, using the oral route avoided the need for intravenous cannulae and their attendant complications.
METHODOLOGY: A prospective observational study carried out over a 2-year period between 2 September 1996 to 2 September 1998. For every training course conducted, the instructors completed a NRP course report form (Form A) that documented the instructors involved in the course. For every participant who attended the course and successfully completed it, the instructors submitted a record form (Form B) that contained the name, hospital address, department, profession, place of work, language used for training and the marks obtained by the individual participant. After each course, completed forms A and B were returned to the NRP secretariat for compilation.
RESULTS: Of the 37 core instructors, 35 (94.6%) carried out training courses in their respective home states. A further 513 new instructors and 2256 providers were trained subsequently. A total of 2806 health personnel from all 13 states of Malaysia were NRP-certified during the first 2 years. However, 61.2% (n = 335) of the 550 instructors were inactive trainers, having trained less than four personnel per instructor a year. Most of the NRP-certified personnel were either doctors (32.0%) or nursing staff (64.4%). More than 60% of these worked either in the labour rooms, neonatal intensive care units or special care nurseries. At least one person from all three university hospitals and all general hospitals, 89.3% (92/103) of the district hospitals, 3.5% (73/2090) of the maternal and child health services, and 21% (46/219) of the private hospitals and maternity homes, were trained in the NRP.
CONCLUSION: Dissemination of the NRP in Malaysia during the first 2 years was very encouraging. Further efforts should be made to spread the program to private hospitals and the maternal and child health services. In view of the large number of inactive instructors, the criteria for future selection of instructors should be more stringent.
