RESUMO

BACKGROUND: On February 6th, 2023, two consecutive earthquakes struck southeastern Türkiye with magnitudes of 7.7 and 7.6, respectively. This study aimed to analyze the clinical and laboratory findings, as well as management of pediatric victims with Crush Syndrome (CS) and Acute Kidney Injury (AKI). METHODS: The study included pediatric earthquake victims who were presented to Mersin University Hospital. Clinical and laboratory characteristics of the patients were collected retrospectively. RESULTS: Among 649 patients, Crush injury (CI), CS and AKI was observed in 157, 59, and 17 patients, respectively. White blood cell count (12,870 [IQR: 9910-18700] vs. 10,545 [IQR: 8355-14057] /µL, P < 0.001), C-reactive protein (51.27 [IQR: 14.80-88.78] vs. 4.59 [1.04-18.25] mg/L, P < 0.001) and myoglobin levels (443.00 [IQR: 198.5-1759.35] vs. 17 [11.8-30.43] ng/ml) were higher in patients with CS, while their sodium (IQR: 134 [131-137] vs. 136 [134-138] mEq/L, P < 0.001) levels were lower compared to non-CS patients. An increase in myoglobin levels was identified as an independent risk factor for developing CS (OR = 1.017 [1.006-1.027]). Intravenous fluid replacement was administered to the patients with CS at a dose of 4000 cc/m2/day. Hypokalemia was observed in 51.9% of the CS patients on the third day. All patients with AKI showed improvement and no deaths were reported. CONCLUSIONS: Hyponatremia and increase in inflammation markers associated with CS may be observed. An increase in myoglobin levels was identified as a risk factor for CS. Hypokalemia may be seen as a complication of vigorous fluid therapy during hospitalization.

RESUMO

BACKGROUND: The safety of long-acting beta-2-adrenergic agonists is increasingly questioned by physicians. Although formoterol is frequently used in childhood, its effects on the autonomic cardiovascular system have not been studied. OBJECTIVE: To investigate the effects of inhaled formoterol on autonomic nervous system using heart rate variability in adolescents with persistent asthma. METHODS: Electrocardiography of 20 asthmatic adolescents (12-20 years) was monitored for 5 specific days. The first day served as basal measurement, and the 2nd and 3rd days reflected the effects of a single and 2 doses of formoterol, respectively. From days 4 to 29, patients received regular treatment with formoterol/budesonide and were monitored on days 30 and 31 to evaluate the development of cardiac and respiratory tolerance after single-dose and 2 doses of formoterol, respectively. Electrocardiographs were analyzed for heart rate, heart rate variability (both time and frequency domain parameters), and spirometry tests were performed. RESULTS: Inhalation of single-dose formoterol increased heart rate and decreased heart rate variability parameters (ratio of the normal-to-normal [NN] interals changing in excess of 50 ms to total of NN intervals [pNN50], total power [TP][ms], TP[ln]) compared with the corresponding baseline values during the first 12 hours of the day. The heart rate variability parameters (pNN50, TP[ms], TP[ln], root mean square of differences between adjacent NN intervals) during the first 12 hours were increased on the 30th day compared with the 2nd day and decreased on the 31st day compared with the 30th day. CONCLUSION: Single-dose formoterol inhalation decreases cardiovagal responsiveness and increases the sympathetic tone in cardiac autonomous control, and regular use of formoterol causes development of tolerance to these effects. However, additive doses of formoterol cause loss of this tolerance.
