目的比较等效小剂量瑞芬太尼和芬太尼对经口气管插管小儿血流动力学反应的影响。方法选择择期行全身麻醉下整形外科手术的患儿100例,美国麻醉医师协会(ASA)Ⅰ级或Ⅱ级,随机平均分为2组:瑞芬太尼组(R组)和芬太尼组(F组),在丙泊酚麻醉诱导中采用盲法应用瑞芬太尼2μg/kg或芬太尼2μg/kg。采用直接喉镜经口气管插管。监测麻醉诱导前(基础值)、气管插管前即刻、气管插管即刻和气管插管1、2、3、4、5min时的血压(BP)和心率(HR),计算各观察时间点BP和HR相对于基础值的变化率,并计算二重指数(RPP)。结果2组BP和HR的基础值及气管插管时间均无显著性差异。与基础值比较,虽然气管插管导致F组的BP、HR、RPP及其观察期最大值显著增高,但R组气管插管时BP、HR、RPP及其观察期最大值均较基础值显著降低。观察期时间点的BP、HR、RPP及其最大值二组比较均有显著性差异,观察期时间点的收缩压(SBP)和HR变化率及观察期其最大变化率2组比较亦有显著性差异。观察期SBP和HR增加>基础值30%的发生率在F组显著高于R组;但观察期SBP和HR降低>基础值30%的发生率在R组显著高于F组。结论在小儿应用异丙酚静脉麻醉诱导时,联合应用等效小剂量瑞芬太尼较芬太尼更能有效抑制经口气管插管的血流动力学反应。芬太尼2μg/kg不足以完全抑制小儿经口气管插管的血流动力学反应。虽然瑞芬太尼2μg/kg能够完全消除小儿经口气管插管的血流动力学反应,但可导致更多不良的心血管功能抑制。 相似文献

Objective
Laryngoscopy and tracheal intubation may cause significant cerebral and systemic hemodynamic responses. Many drugs have been shown to be effective in modifying these hemodynamic responses, including fentanyl, sufentanil, alfentanil and remifentanil. The purpose of the current study was to compare the efficacy of fentanyl, sufentanil, alfentanil and remifentanil on blunting cardiovascular changes during laryngoscopy and intubation in children.Methods
Eighty children, 1–6 years old, classified as American Society of Anesthesiologists physical status I and II who were scheduled for elective surgery with general anesthesia and orotracheal intubation, were enrolled in this randomized and double-blinded study. Patients were randomly assigned into four groups of 20 patients. Group F received fentanyl 1µg/kg−1, group S received sufentanil 0.1 µg/kg−1, group A received alfentanil 10 µg/kg−1 and group R received remifentanil 1 µg/kg−1 intravenously. After establishment of neuromuscular blockade confirmed with a nerve stimulator, laryngoscopy and orotracheal intubation were performed 3 min after induction. Hemodynamic variables including systolic and diastolic blood pressure (SAP, DAP) and heart rate (HR) were recorded at base line (before opioid administration), before laryngoscopy and one minute after orotracheal intubation.Findings
The patients'' characteristics and laryngoscopy grade were similar in all groups. There was no significant difference in the mean values of SAP, DAP and HR at each measured time between the four groups. There was significant difference in the mean values of SAP, DAP and HR measured over time in each group.Conclusion
The intravenous fentanyl attenuated laryngoscopy-induced SAP, DAP and HR increases better than sufentanil, alfentanil or remifentanil and hemodynamic stability is better preserved with fentanyl. 相似文献12.

Mechanically ventilated pediatric intensive care patients usually receive an analgesic and sedative to keep them comfortable
and safe. However, common drugs like fentanyl and midazolam have a long context sensitive half time, resulting in prolonged
sedation and an unpredictable extubation time. Children often awake slowly and struggle against the respirator, although their
respiratory drive and their airway reflexes are not yet sufficient for extubation. In this pilot study, we replaced fentanyl
and midazolam at the final phase of the weaning process with remifentanil and propofol. Twenty-three children aged 3 months–10 years
were enrolled. Remifentanil and propofol revealed throughout excellent or good weaning conditions with rapid transition from
hypnosis to the development of regular spontaneous breathing, airway protective reflexes, and an appropriate level of alertness.
Extubation time following discontinuation of the remifentanil and propofol infusion was only 24 ± 20 min (5–80 min). We conclude
that the combination of remifentanil and propofol is a promising option to improve the weaning conditions of pediatric intensive
care patients. Randomized controlled trials are needed to compare remifentanil and propofol with conventional weaning protocols. 相似文献

A double-blind, randomised controlled study was conducted to evaluate the intubation conditions in 20 preterm neonates following the use of either morphine or remifentanil as premedication. The findings suggest that the overall intubation conditions were significantly better (p=0.0034) in the remifentanil group than in the morphine group. No severe complications were observed in either group. 相似文献

Propofol is a common sedative/anesthetic used for invasive procedures in children with cancer. The purpose of this study was to determine whether families of children with acute leukemia prefer propofol alone or propofol plus fentanyl for lumbar puncture (LP) sedation. We conducted a randomized, placebo controlled, double blind, crossover study. Each patient was studied twice, once with propofol/placebo and once with propofol/fentanyl. Data collected included the modified Yale Preoperative Anxiety Score (M-YPAS) at baseline and after placebo or fentanyl, Induction Compliance Checklist, recovery excitement, recovery time, and adverse events. After the study, families were asked which sedative regimen they preferred for future LPs. Twenty-two patients received 44 LP sedations: propofol 22, propofol/fentanyl 22. The average age was 6.4+/-4.2 years (mean+/-SD). There were no significant differences between groups in M-YPAS, Induction Compliance Checklist or recovery excitement. Adverse events occurred in 11/22 patients (50%) propofol and 4/22 (18.2%) propofol/fentanyl (P=0.0196). Average recovery time (mean+/-SD) was 36.86+/-17.1 minutes propofol versus 26.36+/-16.4 minutes propofol/fentanyl (P=0.047). Sixteen families (72.7%) chose propofol with fentanyl for future LP sedations (P=0.05). In conclusion, most families prefer propofol and fentanyl for LPs. Propofol with fentanyl was also associated with fewer adverse events and faster recovery. 相似文献

OBJECTIVE: We sought to determine whether the combination of propofol and fentanyl results in lower propofol doses and fewer adverse cardiopulmonary events than propofol and placebo for lumbar puncture in children with acute hematologic malignancies. DESIGN: Randomized, controlled, double blind, crossover study. SETTING: Pediatric Sedation Program. PATIENTS: Children with acute leukemia or lymphoma receiving sedation for lumbar puncture. INTERVENTIONS: Each patient received two sedations in random order, one with propofol/placebo and one with propofol/fentanyl. The study investigator and patient/parent were blinded to placebo or fentanyl. Data collected included patient age and diagnosis, propofol dose and adverse events. Adverse events included oxygen saturation <94%, airway obstruction, apnea, hypotension, and bradycardia (<5% mean for age). Logistic regression analysis was used to assess probability of adverse events and the Wilcoxon Signed Rank and McNemar's tests were used for paired comparisons. MEASUREMENTS AND MAIN RESULTS: Twenty-two patients were enrolled. Fourteen patients were male and eight were female. Each patient was studied twice for a total of 44 sedations. The median age was 5.0 yrs (range, 2.2-17.2 yrs). All procedures were successfully completed. The median total dose of propofol was 5.05 mg/kg (range, 2.4-10.2 mg/kg) for propofol/placebo vs. 3.00 mg/kg (range 1.4-10.5 mg/kg) for propofol/fentanyl (p < 0.001). Twelve adverse events occurred in 11 of 22 patients (50.0%) propofol/placebo compared with 6 of 22 (18.2%) propofol/fentanyl (p = 0.02). The most common adverse event was hypotension. CONCLUSIONS: The combination of propofol and fentanyl vs. propofol alone for lumbar puncture sedation in children with acute hematologic malignancies resulted in lower propofol doses and fewer adverse events. 相似文献

Summary In a double-blind study we compared the effectiveness of a meperidine-promethazine-chlorpromazine combination (drug A) and
a fentanyl citrate-droperidol combination (drug B) as sedatives for cardiac catheterization and angiography. The doses for
drug A were meperidine, 1.84 mg/kg; promethazine, 0.46 mg/kg; and chlorpromazine, 0.46 mg/kg; for drug B they were fentanyl
citrate, 1.25μg/kg; and droperidol, 62.5μg/kg. Drug A or B was assigned at random to each of 94 patients aged 3 to 34 years admitted for cardiac catheterization and
was given intramuscularly 30 minutes before catheterization. Each patient who required additional sedation was given intravenously
(IV) one fourth of the original dose of the same medication used for initial sedation. If still further sedation was required,
diazepam, 1 to 2 mg IV, was administered. The effectiveness of sedation or need for additional medication in the group who
received drug A were not significantly different from those in the group who received drug B: supplemental sedation was required
in 8 of 47 (17%) with drug A and 8 of 47 (17%) with drug B. No significant differences between the two groups were noted for
the mean values of heart rate, respiratory rate, oxygen consumption, cardiac index, left ventricular end-diastolic pressure,
arterial oxygen saturation, pH,Po
2, andPco
2 measured during catheterization. No side effects were observed in either group, and all patients had a steady, uneventful
recovery.
We conclude that the meperidine-promethazine-chlorpromazine and the fentanyl-droperidol combinations were equally effective
for precatheterization sedation with the dose used.
