应激状态下新生儿对不同剂量外源性脂肪代谢的研究 总被引:4,自引:0,他引:4
为了探讨应激状态下新生儿应用两种不同剂量脂肪乳剂时的脂肪代谢情况,以指导临床合理应用。将17例胎龄>35周,手术后需TPN>1周的新生儿,随机分成低剂量脂肪乳剂组(1g·kg~(-1)/d)8例,普通剂量对照组(2g·kg~(-1)/d)9例。在TPN前、TPN第3天和第7天分别观察TG、TC、PL、FFA、HDL-C、LDL-C、Apo-A_1和Apo-B变化,结果低剂量组TPN1周期间,TG、TC、PL变化不明显,而对照组TG、TC在TPN第3天升高(但<1.50g/L),第7天回到基值;PL持续升高,Apo-A_1/Apo-B的比值1周变化为:低剂量组1.47→1.60→1.41,对照组1.20→0.85→0.96,它的变化与TG、TC等血脂变化相一致。从研究中得出,足月新生儿TPN时选用1g·kg~(-1)/d对血脂几乎没有影响,用2g·kg~(-1)/d虽然有一过性升高,但仍<1.50g/L,是安全的。 相似文献

Randomized controlled trial of heparin for prevention of blockage of peripherally inserted central catheters in neonates 总被引:7,自引:0,他引:7
Aim: To determine whether the addition of heparin to total parenteral nutrition (TPN) fluid would prevent blockage of peripherally inserted central catheters (PICCs) in neonates. Methods: This was a randomized, double-blind, controlled study of 66 eligible neonates with PICCs inserted for the administration of TPN. Infants were randomized to receive TPN containing either 1 IU ml 31 of heparin (n = 35) or no heparin (n = 31). Results: There was no significant difference in the incidence of blocked catheters between the two groups of infants (heparin: 14.3%; no-heparin: 22.6%, p = 0.4). Although a higher percentage (62.9%) of infants in the heparin group received a complete course of TPN successfully via PICC than those in the no-heparin group (48.4%), the difference was not statistically significant ( p = 0.3). There were no significant differences in the incidence of catheter-related sepsis, hypertriglyceridaemia, hyperbilirubinaemia, coagulopathy or intraventricular haemorrhage between the two groups. Conclusion: Addition of heparin to TPN fluid was not associated with a significant reduction in the incidence of blocked PICCs. However, the sample size of this study was too small to exclude even rather marked differences between the groups. 相似文献

Introduction
Hepatic dysfunction in patients reliant on total parenteral nutrition (TPN) may benefit from cycled TPN. A concern for neonatal hypoglycemia has limited the use of cycled TPN in neonates less than 1 week of age. We sought to determine both the safety and efficacy of cycled TPN in surgical neonates less than 1 week of age.Methods
A retrospective chart review was conducted on surgical neonates placed on prophylactic and therapeutic cycled TPN from January 2013 to March 2016. Specific emphasis was placed on identifying incidence of direct hyperbilirubinemia and hypoglycemic episodes.Results
Fourteen neonates were placed on cycled TPN; 8 were prophylactically cycled and 6 were therapeutically cycled. Median gestational age was 36 weeks (34, 37). Sixty-four percent (n?=?9) had gastroschisis. There was no difference between the prophylactic and therapeutic groups in incidence of hyperbilirubinemia?>?2 mg/dL (3 (37%) vs 5 (83%), p?=?0.08) or the length of time to development of hyperbilirubinemia [24 days (4, 26) vs 27 days (25, 67), p?=?0.17]. Time on cycling was similar though patients who were prophylactically cycled had a shorter overall time on TPN. Three (21%) infants had documented hypoglycemia, but only one infant became clinically symptomatic.Conclusion
Prophylactic TPN cycling is a safe and efficacious nutritional management strategy in surgical neonates less than 1 week of age with low rates of hypoglycemia and a shorter total course of TPN; however, hepatic dysfunction did not appear to be improved compared to therapeutic cycling.13.

The aim of this study was to evaluate prospectively the influence of nutrition on certain factors which may inhibit or promote nephrocalcinosis in two groups of preterm infants, receiving total parenteral nutrition (TPN) and special preterm milk formula respectively, but not furosemide. A total of 37 preterm infants, 15 on TPN and 22 fed a special preterm formula were studied at the end of the 1st, 2nd and 3rd weeks of life, at which time serum and 8 h urine specimens were collected. High ratios of urinary calcium to urinary creatinine (UCa/cr), urinary oxalate to urinary creatinine (Uox/cr) and urinary calcium to urinary citrate (UCa/cit) indicates an increased risk for nephrocalcinosis while high urinary citrate to urinary creatinine (Ucit/cr) ratio indicates protection. Uox/cr increased significantly (P<0.05) in those infants fed preterm formula, from the end of 2nd week of life and was two-fold higher than in the TPN group of preterm infants (P<0.01). Ucit/cr was higher throughout the study period in the formula fed than in the TPN preterm infants. UCa/cit was five-fold higher (P<0.01) in the TPN group, by the end of the 3rd week. Urinary calcium and magnesium was similar in both groups during the study period. Two of the infants studied (5.4%), one from each group, developed nephrocalcinosis.CONCLUSION: In preterm neonates on total parenteral nutrition, urinary oxalate -to-creatinine ratio (a potent lithogenic factor) was lower and urinary citrate -to-creatinine ratio (a lithoprotective factor) also lower than in formula fed neonates. The type of feeding (total parenteral nutrition or special preterm milk formula) seems to affect urinary oxalate and citrate but not calcium and magnesium in non-furosemide treated preterm infants during the first 3 weeks of life. 相似文献

Abstract The study set out to determine the survival times of peripheral total parenteral nutrition (TPN) infusion sites in neonates using a prospective, single blind, randomised trial design. The effects of various concentrations of co-administered heparin was measured using survival analysis, and of other continuous variables using multivariate analysis, against a non-heparinized control group. The study was conducted in special care baby unit located within a specialist maternity hospital in London, United Kingdom. Heparin at 0.1, 0.25, 0.5 and 1 IU/ml was added to TPN infusions delivered through peripheral veins and the survival times of the infusions determined. For infusion sites receiving heparinized fluids, the relative risk of failure decreased and the median survival time increased as the heparin concentration increased, with a maximal effect at a heparin concentration of 0.5 IU/ml (P<0.001). Multivariate analysis using the Cox proportional hazard model confirmed the efficacy of heparin and high-lighted a history of infusion therapy and the co-administration of gentamicin (from a range of drugs analysed) as being risk factors associated with infusion site failure.Conclusion Intravenous infusion survival time can be prolonged using heparin additive at an optimal concentration of 0.5 IU/ml. This should also be of additional interest to paediatricians as heparin is an ubiquitous drug on neonatal units and its clinical use needs to be rationalised. 相似文献

Purpose The recovery of gastrointestinal function following surgery for congenital intestinal atresias can be prolonged and may increase
morbidity and hospital stay. This study was conducted to investigate the prokinetic effect of erythromycin in neonates undergoing
surgery for small bowel atresias.
Methods A randomized-controlled trial was conducted at the Departments of Paediatrics and Paediatric Surgery, Military Hospital, Rawalpindi,
Pakistan, from January to December 2007 to study the prokinetic effect of erythromycin (3 mg/kg per dose 4 times daily). Thirty
consecutive neonates undergoing primary anastomosis for congenital small bowel atresias were randomly divided into two groups:
group I (erythromycin) and group II (control). The groups were similar in terms of gestational age, sex, mode of delivery,
birth weight and types of atresias. Postoperative recovery of intestinal functions was measured as time taken to achieve full
enteral feed (150 ml/kg per 24 h), duration of total parenteral nutrition (TPN) and hospital stay.
Results Neonates receiving oral erythromycin achieved full enteral feeding early (13.07 vs. 16.13 days) required TPN for shorter duration
(10.53 vs. 13.73 days) and their hospital stay was less (16.2 vs. 18.0 days) as compared to the neonates in the control group
who did not receive any erythromycin. The differences were statistically significant.
Conclusion The administration of oral erythromycin following primary anastomosis for small intestinal atresias results in early recovery
of intestinal function, fewer days on TPN and a trend for shorter hospital stay. 相似文献

The pharmacokinetics of ceftriaxone was studied in the plasma, urine, and cerebrospinal fluid of seven neonates and seven infants with meningitis. In addition, plasma and urine data were obtained in five neonates and one infant receiving ceftriaxone for other serious infections. All neonates younger than 14 days received daily doses of 50 mg/kg ceftriaxone; all other patients but two received 100 mg/kg. The average weight-corrected values for total body clearance (ClT), volume of distribution (Vdss), and biologic half-life (t 1/2) were 0.37 ml/min/kg, 0.45 L/kg, and 16.2 hours in neonates younger than 1 week; 0.77 ml/min/kg, 0.48 L/kg, and 9.2 hours in neonates older than 1 week; and 1.03 ml/min/kg, 0.39 L/kg, and 7.1 hours in older infants, respectively. There was a significant difference in ClT and t 1/2 between the neonates younger and both neonates older than 1 week, and infants. The Vdss was not significantly different among the three age groups. The average renal clearance in neonates younger than 1 week (0.28 ml/min/kg was 70%, in neonates older than 1 week (0.54 ml/min/kg) was 77%, and in older infants (0.49 ml/min/kg) was 47% of ClT, indicating that nonrenal elimination was less developed in neonates. The quantitation of CSF diffusion of ceftriaxone was assessed by comparison of the areas under the CSF and plasma concentration-time curve. The mean ceftriaxone penetration into the CSF in neonates and infants with bacterial meningitis was 17%. On the other hand, penetration in patients with aseptic meningitis amounted to only 4%. Mean ceftriaxone concentrations in the CSF in patients with bacterial meningitis were 2.8 mg/L after 24 hours, exceeding by many times the minimum inhibitory concentration of the common meningitis pathogens at this time. 相似文献

Carnitine plays an important role in the oxidation of fatty acids by facilitation their transport across the mitochondrial membrane. Premature infants are known to have a limited capacity for fatty acid oxidation. To investigate the relationship between carnitine blood concentrations and the ability to utilize exogenous fat, plasma concentrations of total carnitine, free carnitine, free fatty acids and triglyceride were measured in 29 parenterally alimented neonates, including 10 pre-term infants and 19 full:term infants, prior to and during TPN. The pre-term infants achieved very high plasma levels of free fatty acids and very low levels of free carnitine during TPN. There was a highly negative correlation between plasma concentrations of free fatty acids and those of free carnitine. The present study suggests the possible therapeutic advantages of supplementing carnitine in intravenously alimented neonates, especially in pre-term infants. 相似文献

A prospective study was performed to assess the frequency and diagnostic utility of lumbar punctures in neonates both during their first week of life and thereafter. During the two 6-month periods from January 1, 1985 to June 30, 1985, and February 1, 1986 to July 31, 1986, 712 neonates underwent 728 lumbar punctures during their first week of life primarily as part of the evaluation for suspected infection, either congenital or postnatal. There were eight patients with positive spinal fluid cultures in the first week of life, but only one patient simultaneously had a positive blood culture and a clinical course consistent with meningitis. In contrast, a considerably higher yield, approximating five times that of the first week of life, was obtained in patients undergoing a lumbar puncture after the first week of life. 相似文献
