RESUMO

Objectives: Sedation and stability during electroencephalography (EEG) in pediatrics have high clinical importance. This study compares the sedative properties of oral chloral hydrate (OCH) and intranasal fentanyl (INF). Materials & Methods: This study was a randomized clinical trial conducted in 2020 in Isfahan City on sixty-two pediatric candidates for EEG. Patients were randomized into two groups receiving 50 mg/kg OCH and 2 µg/kg INF thirty minutes before the process. The heart rate (HR), mean arterial pressure (MAP), respiratory rate (RR), and oxygen saturation (O2 sat) of patients, sedation, and physician's satisfaction were measured and compared between groups. Results: The HR of patients decreased significantly in both groups (P< 0.001), and the patients that received INF had significantly lower HR 15, 30, 45, and 60 minutes after drug administrations (P< 0.05). RR evaluation indicated significantly decreased RR in both groups (P< 0.001), and patients receiving INF had lower RR 30, 45, and 60 per minutes after drug administrations (P< 0.001). Both groups showed significantly increased sedation levels during the study (P< 0.001), and patients treated with INF had higher sedation levels 15, 30, and 45 minutes after drug administration. Satisfaction rates were higher among the group that received INF (P= 0.020). Conclusion: The use of INF had significant analgesic and sedative effects on pediatrics undergoing EEG.

RESUMO

BACKGROUND: Renal ischemia-reperfusion (IR) injury has numerous deleterious effects on the kidney function. An experimental investigation was conducted to determine the possible protective role of testosterone (TES) and zinc (Zn) supplementations on the kidney function after IR injury in orchiectomized rats. METHODS: Orchiectomized rats (n = 32) were divided into the five groups as sham operated (Group 1), IR (Group 2), IR pretreatment with TES (IR + TES, Group 3), Zn (IR + Zn, Group 4), and TES + Zn (IR + TES + Zn, Group 5). Twenty-four hours' post-IR injury, the animals were sacrificed and the required parameters were measured. RESULTS: The results revealed that there were not any significant difference in serum levels of creatinine (Cr), nitrite and malondialdehyde (MDA), Cr clearance (ClCr), renal sodium (Na) load, and percentage of Na excretion (ENa%) between sham and IR groups. The pretreatment with TES and Zn either alone or combine did not alter the serum levels of Cr, nitrite and MDA, and ClCr, Na load, and ENa%. However, pretreatment with Zn, TES, or combined altered kidney weight, kidney tissue levels of nitrite and MDA, and urine flow in IR groups. CONCLUSIONS: The orchiectomy itself performed protective effect against renal IR injury. However, pretreatment with Zn or TES may not alter kidney function against renal IR in orchiectomized rats.
