Efficacy of nalbuphine combined with propofol for esophageal dilation with gastroscope in pediatric patients / 中华麻醉学杂志

ABSTRACT

Objective:To evaluate the effect of nalbuphine combined with propofol for esophageal dilation with gastroscope in the pediatric patients.Methods:A total of 150 pediatric patients with esophageal stenosis, aged 6 months-2 yr, weighing 6-15 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective painless balloon dilation with gastroscope under general anesthesia, were randomized into 3 groups ( n=50 each) according to the random number table method: nalbuphine 0.1 mg/kg plus propofol group (N 1P group), nalbuphine 0.2 mg/kg plus propofol group (N 2P group), and fentanyl plus propofol group (FP group). Nalbuphine 0.1 and 0.2 mg/kg and fentanyl 1 μg/kg were intravenously injected in N 1P, N 2P and FP groups, respectively, and 2 min later propofol 1.5-2.0 mg/kg was intravenously injected for sedation until the eyelash reflex disappeared in the three groups.Propofol 1.0 mg/kg was added when body movement occurred during surgery.The amount of propofol consumed during surgery, occurrence of body movement and respiratory depression, occurrence of adverse reactions such as postoperative nausea and vomiting, and laryngospasm, emergence time, Face Legs Activity Cry Consolability (FLACC) pain scale score and surgeons′ satisfaction were recorded. Results:Compared with group N 1P, the consumption of propofol, body movement classification ratio and FLACC score were significantly decreased, and the emergence time was shortened in group N 2P ( P<0.05), and no significant change was found in the parameters mentioned above in group FP ( P>0.05). There was no significant difference in the incidence of perioperative adverse reactions and degree of surgeons′ satisfaction among the three groups ( P>0.05). Conclusion:Nalbuphine combined with propofol can provide satisfactory anesthetic efficacy with fewer adverse reactions when used for esophageal dilation with gastroscope in the pediatric patients.
