■该研究的目的是评估在全麻(GA)下接受手术的儿科人群中qCON和qNOX指数的表现,专注于诱导期和恢复期。这两个指标都来自脑电图(EEG),并在CONOX监测器(FreseniusKabi,德国)。
■机构伦理委员会批准后,这项前瞻性观察性研究是在美国麻醉学会(ASA)I级和II级接受GA择期手术的儿童患者中进行的.麻醉技术为GA,有或没有区域镇痛(RA)。所有患者均使用七氟醚进行吸入诱导和维持。使用CONOX监测系统(FreseniusKabi,德国),通过一组放置在额头上的电极连接。在清醒期间记录qCON和qNOX评分(在口服咪达唑仑0.5mg/kg的手术台上),在感应时,睫毛反射丧失时,插管/喉罩气道(LMA)插入,区域麻醉前后,手术切口,在麻醉停止时,出现,拔管,大开眼界。还与七氟醚(MAC)的最低肺泡浓度进行了比较分析。
■共有46名儿科患者被纳入研究,平均年龄为5.6岁。所有患者均为ASAI或ASAII。在诱导和恢复时,qCON和qNOX同时下降和上升,分别。与RA无关,手术切口的qNOX升高。然而,在未接受RA治疗的患者中,手术切口后qNOX的升高幅度更大(P=0.33)。此外,在儿童人群中,qCON(P=0.06)和qNOX(P=0.41)与七氟醚MAC值的相关性均较差.
■qCON和qNOX值均随着意识水平的变化和不同的有害刺激而可预测地变化。需要进一步的研究来确认这些发现,同时考虑到谵妄的术后评估和术中事件的回忆。
UNASSIGNED: The objective of the study was to evaluate the performances of qCON and qNOX indices in pediatric populations undergoing surgery under general anesthesia (GA), focusing on the induction and recovery periods. Both the indices are derived from electroencephalogram (EEG) and implemented in the CONOX monitor (Fresenius Kabi, Germany).
UNASSIGNED: After approval of the institutional ethics committee, this prospective observational study was conducted in pediatric patients of either sex in the age group of 1-12 years belonging to the American Society of Anesthesiology (ASA) grade I and II undergoing elective surgery under GA. Anesthetic technique was GA with or without regional analgesia (RA). All patients underwent inhalation induction and maintenance using sevoflurane. Patients were monitored with the use of a CONOX monitoring system (Fresenius Kabi, Germany), connected via a set of electrodes placed over the forehead. qCON and qNOX scores were recorded during awake (on operating table premedicated with oral midazolam 0.5 mg/kg), at induction, at loss of eyelash reflex, intubation/laryngeal mask airway (LMA) insertion, before and after regional anesthesia, surgical incision, at cessation of anesthesia, emergence, extubation, and eye-opening. Registered results were also analyzed compared with the minimum alveolar concentration of sevoflurane (MAC).
UNASSIGNED: A total of 46 pediatric patients were enrolled in the study with a mean age of 5.6 years. All the patients were either ASA I or II. There was a simultaneous fall and rise of qCON and qNOX upon induction and recovery, respectively. There was a rise in qNOX with surgical incision irrespective of RA. However, there was a greater rise in qNOX following surgical incision in those who did not receive RA (P = 0.33) Also both qCON (P = 0.06) and qNOX (P = 0.41) were poorly correlated with MAC values of sevoflurane during GA in the pediatric population.
UNASSIGNED: Both qCON and qNOX values change predictably with changes in the conscious level and with different noxious stimuli. Further studies are required to confirm the findings taking into account the postoperative assessment of delirium and recall of intraoperative events.
