Desflurane and Sevoflurane in Pediatrics With Elevated Liver Enzymes

Not Applicable

• Conditions: Liver Functions Tests
• Interventions: Drug: Desflurane; Drug: Sevoflurane

• Registration Number: NCT04775212
• Lead Sponsor: National Cancer Institute, Egypt

Brief Summary

It is designed to compare effects of inhaled anaesthetic desflurane and sevoflurane on liver functions in pediatric cancer patients

Detailed Description

Patients will be randomly allocated into two groups using a sealed envelope technique: desflurane group (Des group, n = 30) and sevoflurane group (sevo group, n = 30).

Anesthesia monitoring included electrocardiogram, continuous arterial and pulse oximetry, capnography, urine output, nerve stimulator, and esophageal core temperature.

Anesthesia will be induced with Propofol 2 mg/kg ,FentanyL 2 μg/kg and atracurium (0.5 mg/kg) was administered to achieve muscle relaxation before endotracheal intubation. End-tidal desflurane or sevoflurane concentrations during the induction were limited to 2 minimal alveolar concentration (MAC). Concentrations of inhalational anesthetics were measured using an anesthetic gas analyser (Datex-Ohmeda, Helsinki, Finland). For the maintenance of anesthesia, the inspired desflurane or sevoflurane concentration was carefully titrated to maintain the end-tidal concentration of 1 MAC. A constant fresh gas flow of 3 l/min (medical-grade air in oxygen to make inspiratory oxygen fraction 0.5) was used during the maintenance of anesthesia. Ventilation was controlled with a tidal volume of 7-10 ml/kg and ventilatory rate was adjusted to maintain an end tidal carbon dioxide ( CO2 )of 35-40 mmHg. to maintain intraoperative blood pressure (BP) and heart rate (HR) within 20% of preoperative values. additional Atracurium will be administered as appropriate. Nerve stimulator was used to monitor neuromuscular blockade on the right adductor pollicis. Hypotension (a drop in systolic BP to the extent of 30% or more or the systolic BP being less than the preoperative values) was treated with volume replacement and, when necessary, with intravenous ephedrine in incremental doses .Bradycardia (HR \< 50 beats per min) was treated with atropine if needed.

Aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TB), prothrombin time (PT) expressed in international normalized ratio (INR), albumin, platelet count (PLT), and hemoglobin (Hb) were analysed at preoperative period, immediately after operation, and on the 1st, 2nd, 3rd, 5th and 7th, postoperative days (PODs).
