Disease relevance of Monitoring, Intraoperative

• METHODS: A total of 17 patients, most of whom presented with transient ischemic attacks or fluctuating neurological deficits, underwent intraoperative monitoring of their SjO2 and end-tidal carbon dioxide (ETCO2) after a state of anesthesia had been induced with isoflurane (Group 1) or propofol (Group 2) [1].
• The usefulness of the PTH assay extends from the traditional diagnosis of parathyroid disease to intraoperative monitoring, helping to ensure a higher cure rate [2].
• Invasive monitoring/intraoperative electrocorticography is recommended for patients with suspected cortical dysplasia on MRI or for the patients with persistent epilepsy after ganglioglioma resection [3].
• However, possible cardiovascular changes during CO2 pneumoperitoneum necessitate close intraoperative monitoring [4].

High impact information on Monitoring, Intraoperative

• Its value for assessing collateral circulation, intraoperative monitoring, and measuring CBF is quite promising [5].
• BACKGROUND: Immunoassays for parathyroid hormone (PTH), with short incubation times and results available in <15 min, have allowed intraoperative monitoring of the success of parathyroid surgery [6].
• Intraoperative monitoring of kinetic total serum calcium levels in primary hyperparathyroidism surgery [7].
• Both phenomena can be addressed by a practical method to refine intraoperative monitoring by individually optimizing scalp derivations and identifying topographic P37 changes during surgery [8].
• Other uses for ECochG also are presented (e.g. intraoperative monitoring, enhancement of ABR wave I, estimation of hearing sensitivity) [9].

Biological context of Monitoring, Intraoperative

• The results of intraoperative monitoring of median nerve somatosensory evoked potentials (SEP's) were evaluated in 75 neurosurgical patients in order to assess the role of differential derivation of brain stem (P14) and spinal cord (N13) wave activity [10].
• In conclusion, intraoperative monitoring of descending pathways by means of motor evoked potentials during anesthesia with the inhalational agents halothane, enflurane and isoflurane is only feasible when neural activity is evaluated [11].
• In addition, ECoG may be used to enhance our ability to observe the most peripheral component of the auditory brain stem response (Wave I) for routine clinical assessment or during intraoperative monitoring procedures in which certain structures of the ear are at risk for permanent damage [12].

Anatomical context of Monitoring, Intraoperative

• Adopting intraoperative monitoring of the facial nerve and the cochlea as well as the Pars acustica by means of far-field and near-field electrodes, a good facial 'mobility' was achieved in 95.3%, and a useful audition (AAO-HNS Types A and B) in 60% [13].
• METHODS: We describe a patient with recurrent secondary hyperparathyroidism attributable to a mediastinal parathyroid gland who underwent parathyroidectomy with use of VATS, intraoperative 99mTc-sestamibi scanning (gamma probe), and intraoperative monitoring of intact parathyroid hormone (iPTH) [14].

Associations of Monitoring, Intraoperative with chemical compounds

• We conclude that N2O can be used as an anesthetic adjunct without a significant deleterious effect on MEPs during intraoperative monitoring in patients under propofol anesthesia, providing concentrations are maintained below 50% [15].
• Intraoperative monitoring of anti-factor Xa activity was performed, and additional doses of heparin were given on the basis of anti-factor Xa results [16].
• Etomidate was the least detrimental anesthetic agent for intraoperative monitoring of magnetic MEP [17].
• Isoflurane compared with nitrous oxide anaesthesia for intraoperative monitoring of somatosensory-evoked potentials [18].
• Halothane is not ideal however when monitoring intraoperative VEP [19].

Gene context of Monitoring, Intraoperative

• Most of these procedures utilize preoperative localization and intraoperative monitoring of parathyroid hormone [20].
• Tibial somatosensory evoked potential intraoperative monitoring: recommendations based on signal to noise ratio analysis of popliteal fossa, optimized P37, standard P37, and P31 potentials [21].
• Intraoperative monitoring of MEP could be performed at a M-response amplitude above 90 % of the baseline value in 10 patients and at a M-response amplitude of 20%-50% of the baseline value in 11 patients [22].
• Intraoperative monitoring in patients with moyamoya disease [23].
• OBJECTIVES: To analyse four years of CEA with respect to the underlying mechanisms of perioperative stroke and the role of intraoperative monitoring in the prevention of stroke [24].

Analytical, diagnostic and therapeutic context of Monitoring, Intraoperative

• PATIENTS: During a 2(1/2)-year period, 130 patients underwent minimally invasive, targeted parathyroidectomy with intraoperative monitoring of the parathyroid hormone level [25].
• Modification to a commercial immunoradiometric assay permitting intraoperative monitoring of parathyroid hormone levels [26].
