“…The two-channel mode is peculiar to the Narcotrend and is not available in other currently commercially available processed EEG monitors. In this mode, raw EEG data from both hemispheres of the brain are collected and displayed simultaneously on top of each other on the upper half of the monitor screen allowing the user to visually compare the signals from both sides 23 24…”

A 9-year-old female with Trisomy 21 with complex craniovertebral instability causing severe cervicomedullary compression underwent occipitocervical fusion. This paper will discuss the anaesthetic management and highlight the use of the Narcotrend monitor not only as a depth of consciousness monitor but more importantly as a tool to detect surgery-induced cerebral hypoperfusion by monitoring the right and left cerebral hemispheres independently and simultaneously.

“…Intra operative depth of anaesthesia was monitored using clinical signs like rise in blood pressure, pulse, limb movements, lacrimation and sweating. [16][17][18] Propofol drip was stopped as soon as surgery ended and vitals were noted (T9). Duration of surgery was noted from the start of incision/procedure to the end of surgery.…”

Background: Total intravenous anaesthesia is a technique in which induction and maintenance of anaesthesia is achieved with intravenous drug alone. With analgesics complete anaesthesia can be achieved. Objectives: To study & compare the hemodynamic profile, intra operative analgesic adequacy, VAS score and emergence time between two groups. Subjects and Methods: Total 80 patients of ASA grade I & II, aged 18-60years old, who were posted for short surgical procedures were randomly divided into two groups. Group I received Inj.Butorphanol 20μg/kg and Group II received Inj.Fentanyl 2μg/kg body weight. Both the groups received Inj. Propofol 2mg/kg I.V. and then maintenance of anaesthesia started with Propofol as a stepped down scheme. Intra operative depth of anaesthesia was monitored using clinical signs like rise in blood pressure, pulse and respiratory rate. Post-operative sedation score was noted using Ramsay Sedation score. Visual analogue score for pain, was noted at the time of emergence time. Results: Respiratory rate, heart rate and SpO2 showed no significant differences between groups. Average systolic and diastolic BP in group I was lower as compared to group II during the surgery and post-operative at the time of emergence also. Mean emergence time in group I was significantly higher than group II. Mean VAS at the time of emergence was significant less in butorphanol group. Conclusion: From the present study it can be concluded that, Butorphanol & Fentanyl combined with Propofol are comparable in hemodynamic profile. Post-operative more time is taken for emergence in Butorphanol group. VAS score for pain at the time of emergence is more in Fentanyl group compared to Butorphanol. With conventional monitoring, depth of anaesthesia is satisfactory between groups. With both the drugs satisfactory anaesthesia can be provided for short surgical procedures which are 30 or less in duration.

“…[ 59 ] Until date, no monitoring system can reliably measure the DOA for all patients and all anesthetic agents. [ 60 ] Moreover, all DOA monitor can measure the hypnotic component and not the patient's stress level in response to nociceptive stimulus during GA.[ 61 ] Monitoring of the stress response is equally important as prolonged stress response delays recovery and increases the perioperative morbidity. [ 62 ] Various other indices like surgical stress index (SSI), the response index of nociception and the noxious stimulation response index have been found to be superior to BIS and AAI index.…”

Minimal mandatory monitoring in the perioperative period recommended by Association of Anesthetists of Great Britain and Ireland and American Society of Anesthesiologists are universally acknowledged and has become an integral part of the anesthesia practice. The technologies in perioperative monitoring have advanced, and the availability and clinical applications have multiplied exponentially. Newer monitoring techniques include depth of anesthesia monitoring, goal-directed fluid therapy, transesophageal echocardiography, advanced neurological monitoring, improved alarm system and technological advancement in objective pain assessment. Various factors that need to be considered with the use of improved monitoring techniques are their validation data, patient outcome, safety profile, cost-effectiveness, awareness of the possible adverse events, knowledge of technical principle and ability of the convenient routine handling. In this review, we will discuss the new monitoring techniques in anesthesia, their advantages, deficiencies, limitations, their comparison to the conventional methods and their effect on patient outcome, if any.
