SummaryPer cent aggregation, release and content of adenine nucleotides, and specific radioactivity were evaluated in citrated platelet-rich plasma (PRP) prepared from paired samples of maternal and cord blood. Platelets of newborn infants aggregated normally in response to high dose ADP (20 μM), strong collagen suspensions, and thrombin; however, when compared with PRP from the mothers or from normal adults, per cent aggregation in response to lower concentrations of ADP (2 μM), weak collagen, and part particularly epinephrine was markedly reduced. Nucleotide release after stimulation of the newborns’ PRP with the latter two inducers was also impaired. ATP and ADP content of the newborns’ platelets was also significantly less than that of their mothers or of normal adults, but specific activity was normal. The data suggest that the impairment of ADP release in the platelets of newborn infants is due to decreased sensitivity to external stimuli. Since metabolic ATP is necessary for the platelet release reaction, it is postulated that the platelet dysfunction results from a lack of metabolic ATP.

OBJECTIVES Postoperative fluid overload is ubiquitous in neonates and infants following operative intervention for congenital heart defects; ineffective diuresis is associated with poor outcomes. Diuresis with furosemide is widely used, yet there is often resistance at higher doses. In theory, furosemide resistance may be overcome with chlorothiazide; however, its efficacy is unclear, especially in lower doses and in this population. We hypothesized the addition of lower-dose, intravenous chlorothiazide following surgery in patients on high-dose furosemide would induce meaningful diuresis with minimal side effects. METHODS This was a retrospective, cohort study. Postoperative infants younger than 6 months, receiving high-dose furosemide, and given lower-dose chlorothiazide (1–2 mg/kg every 6–12 hours) were identified. Diuretic doses, urine output, fluid balance, vasoactive-inotropic scores, total fluid intake, and electrolyte levels were recorded. RESULTS There were 73 patients included. The addition of lower-dose chlorothiazide was associated with a significant increase in urine output (3.8 ± 0.18 vs 5.6 ± 0.27 mL/kg/hr, p < 0.001), more negative fluid balance (16.1 ± 4.2 vs −25.0 ± 6.3 mL/kg/day, p < 0.001), and marginal changes in electrolytes. Multivariate analysis was performed, demonstrating that increased urine output and more negative fluid balance were independently associated with addition of chlorothiazide. Subgroup analysis of 21 patients without a change in furosemide dose demonstrated the addition of chlorothiazide significantly increased urine output (p = 0.03) and reduced fluid balance (p < 0.01), further validating the adjunct effects of chlorothiazide. CONCLUSION Lower-dose, intravenous chlorothiazide is an effective adjunct treatment in postoperative neonates and infants younger than 6 months following cardiothoracic surgery.

Residual Urine

Among 55 uremic patients who entered our CAPD program, 7 of them showed a reduction or loss of the ultrafiltration capacity (UF) of the peritoneal membrane (PM). They have been treated with high dose of Furosemide (F) to force residual urine output. Four appeared «responders» to drug administration with a significant increase in urine volume, Na excretion and, within a week period gained their dry body weight (BW). In the remaining 3 patients drug therapy resulted ineffective, and fluid removal was obtained by hemofiltration (HF). In both groups we noted an increase in the UF capacity of PM when their dry BW was obtained either by pharmacological or technical approach. These results support the assumption that the overhydration status of the PM plays a major role in maintaining the UF process.

Objective: To evaluate the clinical effects of continuous intravenous infusion with high-dose furosemide on early acute kidney injury (AKI) complicated with acute lung edema. Methods: Ninety patients who had been treated by furosemide at routine dose for 12 hour but with unsatisfactory outcomes were selected and subjected to continuous intravenous infusion with high-dose furosemide. The dose was adjusted according to hourly urine output. Serum levels of urea nitrogen, creatinine and potassium, pH, oxygenation index and mechanical ventilation time before and 6, 12, 24, 48 and 72 hour after treatment were compared. Results: The urine outputs before and 6, 12, 24, 48 and 72 hour after treatment were (10.71±1.81), (164.52±21.42), (189.71±29.61), (181.33±23.52), (176.82±24.80) and (164.52±18.91) ml/h respectively. Compared with data before treatment, the serum levels of urea nitrogen, creatinine and potassium significantly decreased while pH and oxygenation index significantly increased after six hour of treatment (P<0.05). After treatment, the kidney functions of 80 patients (88.9%) were completely recovered, without obvious adverse reactions. Conclusion: For patients with early AKI complicated with acute pulmonary edema who cannot be cured by diuretic agent at routine dose, high-dose furosemide increases urine output and improves success rate. doi: https://doi.org/10.12669/pjms.35.3.1012 How to cite this:Ni J, Jiang H, Wang F, Zhang L, Sha D, Wang J.

Congenital chylothorax (CC) is a rare entity in neonatal period requiring multimodal management strategies. Despite optimum treatment, some cases remain refractory posing significant challenge to the treating physician. We here describe a 33-week preterm neonate presenting with refractory congenital chylothorax who needed treatment with combination of skimmed milk, high dose and prolonged duration octreotide for resolution. This case highlighted that octreotide has a good safety profile in newborn infants with congenital chylothorax and locally available skimmed milk fortified with medium chain triglyceride (MCT) oil is a cheap and safe alternative.

Renal parathyroid hormone (PTH) action is often studied at high doses (100 μg PTH/kg) that lower mean arterial pressure significantly, albeit transiently, complicating interpretation of studies. Little is known about the effect of acute hypotension on proximal tubule Na+ transporters. This study aimed to determine the effects of acute hypotension, induced by aortic clamp or by high-dose PTH (100 μg PTH/kg), on renal hemodynamics and proximal tubule Na/H exchanger isoform 3 (NHE3) and type IIa Na-Pi cotransporter protein (NaPi2) distribution. Subcellular distribution was analyzed in renal cortical membranes fractionated on sorbitol density gradients. Aortic clamp-induced acute hypotension (from 100 ± 3 to 78 ± 2 mmHg) provoked a 62% decrease in urine output and a significant decrease in volume flow from the proximal tubule detected as a 66% decrease in endogenous lithium clearance. There was, however, no significant change in glomerular filtration rate (GFR) or subcellular distribution of NHE3 and NaPi2. In contrast, high-dose PTH rapidly (<2 min) decreased arterial blood pressure to 51 ± 3 mmHg, decreased urine output, and shifted NHE3 and NaPi2 out of the low-density membranes enriched in apical markers. PTH at much lower doses (<1.4 μg·kg−1·h−1) did not change blood pressure and was diuretic. In conclusion, acute hypotension per se increases proximal tubule Na+ reabsorption without changing NHE3 or NaPi2 subcellular distribution, indicating that trafficking of transporters to the surface is not the likely mechanism; in comparison, hypotension secondary to high-dose PTH blocks the primary diuretic effect of PTH but does not inhibit the PTH-stimulated redistribution of NHE3 and NaPi2 to the base of the microvilli.

Vasopressin (AVP) in acute experiments has been shown to influence cardiovascular reflexes, but the effect of a more prolonged administration of AVP on the sympathetic nervous system has not been investigated. Long–Evans rats were treated for 7 days with AVP (Pitressin tannate in oil, with single daily doses of 100 or 500 mU∙100 g−1, s.c.) to determine whether AVP alters norepinephrine (NE) turnover in kidney, intestine, or skeletal muscle. Control rats were given equal doses of peanut oil daily. NE turnover was determined by measuring the decline in tissue levels of NE for 8 h after inhibition of tyrosine hydroxylase with α-methyl-p-tyrosine (300 mg∙kg−1, i.p. every 4 h). Measurements of water intake, urine output, and urine osmolality showed that chronic administration of the high dose, but not the low dose, of AVP produced maintained increases in urine osmolality and decreases in water intake and urine output. Body weight, plasma osmolality, plasma electrolytes, and hematocrit were not significantly altered by AVP treatment, but mean arterial pressure was elevated significantly (control, 105 ± 3 mmHg versus AVP, 119 ± 4 mmHg, p < 0.05) (1 mmHg = 133.3 Pa) in the high dose group. Plasma renin activity was decreased slightly, but significantly in rats treated with the high dose of AVP. Compared with results in control animals, there were no statistically significant changes in NE turnover after chronic administration of either the low or the high dose of AVP. The results indicate that administration of AVP for 7 days to rats in normal fluid balance does not result in a decrease in NE turnover in peripheral organs.

Abstract Background Administration of an optimal dose of anesthetic agent to ensure adequate depth of hypnosis with the lowest risk of adverse effects to the fetus is highly important in cesarean section. Sodium thiopental (STP) is still the first choice for induction of anesthesia in some countries for this obstetric surgery. We aimed to compare two doses of STP with regarding the depth of anesthesia and the condition of newborn infants. Methods In this clinical trial, parturient undergoing elective Caesarian section were randomized into two groups receiving either low-dose (5 mg/kg) or high-dose (7 mg/kg) STP. Muscle relaxation was provided with succinylcholine 2 mg/kg and anesthesia was maintained with O2/N2O and sevoflurane. The depth of anesthesia was evaluated using isolated forearm technique (IFT) and bispectral index (BIS) in various phases. Additionally, infants were assessed using Apgar score and neurobehavioral test. Results Forty parturient were evaluated in each group. BIS was significantly lower in high-dose group at skin incision to delivery and subcutaneous and skin closure. Also, significant differences were noticed in IFT over induction to incision and incision to delivery. Apgar score was significantly lower in high-dose group at 1 min after delivery. Newborn infants in low-dose group had significantly better outcomes in all three domains of the neurobehavioral test. Conclusion 7 mg/kg STP is superior to 5 mg/kg in creating deeper hypnosis for mothers. However, it negatively impacts Apgar score and neurobehavioral test of neonates. STP seems to has dropped behind as an acceptable anesthetic in Cesarean section. Trial registration IRCT No: 2016082819470 N45, 13/03/2019.
