“…In all patients, an epidural procedure was completed by one or two needle insertions within 10 min. Ramsay's score in most patients was level 2 (patient cooperative, oriented, and calm [6]); however, level 1 (patient anxious and agitated or restless or both [6]) was observed in one patient in the control group and level 3 (patient responds to commands only [6]) in one patient in the F50 group.…”

Comparisons of two different doses of fentanyl for procedural analgesia during epidural catheter placement: a double-blind prospective, randomized, placebo-controlled study

The purpose of this study was to investigate the effect of fentanyl on analgesic properties and respiratory responses during an epidural procedure. Sixty patients premedicated with oral brotizolam 0.25 mg were allocated to receive procedural analgesia with saline or 25 or 50 μg of fentanyl. Five minutes after administration, an epidural procedure was started. Pain assessments were made immediately after the epidural catheter placement using a visual analog scale. The lowest SpO₂ levels during the procedure were recorded to evaluate respiratory depression, and cardiovascular complications were also recorded. The pain scores were significantly lower in the 25 and 50 μg fentanyl groups than in the placebo group (P < 0.01). There was no difference in pain assessment between the 25 and 50 μg fentanyl groups. The lowest SpO₂ value of the 50 μg fentanyl group was significantly lower than those of the other groups (P < 0.001). Seven of 20 cases in the 50 μg fentanyl group needed oxygen administration because of a decreased SpO₂ value (<94%). No cardiovascular complications were observed in any group during the entire study period. Thus, intravenous fentanyl at a dose of 25 μg provides effective procedural analgesia without the risk of hypoxemia during an epidural procedure in a patient with preanesthetic medication.

“…The combination of the EEG and EMG response is the basis of the response entropy, and the isolated low frequency signal of the EEG indicates the state entropy. A study in critically ill adult patients analysed its correlation with the BIS and Ramsay scale, finding a good correlation between the three indices [66].…”

Monitoring sedation in the critically ill child

SummarySedation is an essential part of the management of the critically ill child, and its monitoring must be individualised and continuous in order to adjust drug doses according to the clinical state. There is no ideal method for evaluating sedation in the critically ill child. Haemodynamic variables have not been found to be useful. Clinical scales are useful when sedation is moderate, but are limited by their subjective nature, the use of stimuli, and the impossibility of evaluating profoundly sedated patients or those receiving neuromuscular blocking drugs; in addition, many of these scales have not been evaluated in children. The COMFORT scale is the most appropriate, as it was designed and validated for critically ill children requiring mechanical ventilation. Electroencephalography‐derived methods permit continuous monitoring, provide an early indication of changes in the level of sedation, and facilitate a rapid adjustment of medication. However, these methods were designed and validated for patients under anaesthesia and their results cannot be fully extrapolated to the critically ill patient; in addition, some of them have not been validated in small children and there is still little experience in critically ill children. The main indications for the use of these methods are in patients with deep sedation and/or neuromuscular blockade. The bispectral index is the most widely used method at the present time. Analysis and comparison of the efficacy of the different methods for evaluating sedation in the critically ill child is required.

Comparing Entropy and the Bispectral Index with the Ramsay Score in Sedated ICU Patients

Abstract: ENTROPY, BIS and Ramsay score values correlate significantly in sedated postoperative ICU patients. ENTROPY does not appear superior to BIS for the assessment of sedation in this context.
