  • Monitoring Anesthetic Depth
    ANESTHETIC MONITORING Lyon Lee DVM PhD DACVA MONITORING ANESTHETIC DEPTH • The central nervous system is progressively depressed under general anesthesia. • Different stages of anesthesia will accompany different physiological reflexes and responses (see table below, Guedel’s signs and stages). Table 1. Guedel’s (1937) Signs and Stages of Anesthesia based on ‘Ether’ anesthesia in cats. Stages Description 1 Inducement, excitement, pupils constricted, voluntary struggling Obtunded reflexes, pupil diameters start to dilate, still excited, 2 involuntary struggling 3 Planes There are three planes- light, medium, and deep More decreased reflexes, pupils constricted, brisk palpebral reflex, Light corneal reflex, absence of swallowing reflex, lacrimation still present, no involuntary muscle movement. Ideal plane for most invasive procedures, pupils dilated, loss of pain, Medium loss of palpebral reflex, corneal reflexes present. Respiratory depression, severe muscle relaxation, bradycardia, no Deep (early overdose) reflexes (palpebral, corneal), pupils dilated Very deep anesthesia. Respiration ceases, cardiovascular function 4 depresses and death ensues immediately. • Due to arrival of newer inhalation anesthetics and concurrent use of injectable anesthetics and neuromuscular blockers the above classic signs do not fit well in most circumstances. • Modern concept has two stages simply dividing it into ‘awake’ and ‘unconscious’. • One should recognize and familiarize the reflexes with different physiologic signs to avoid any untoward side effects and complications • The system must be continuously monitored, and not neglected in favor of other signs of anesthesia. • Take all the information into account, not just one sign of anesthetic depth. • A major problem faced by all anesthetists is to avoid both ‘too light’ anesthesia with the risk of sudden violent movement and the dangerous ‘too deep’ anesthesia stage.

Key Messages Purpose of review To evaluate home noninvasive positive pressure ventilation (NIPPV) in adults with chronic respiratory failure in terms of initiation, continuation, effectiveness, adverse events, equipment parameters and required respiratory services. Devices evaluated were home mechanical ventilators (HMV), bi-level positive airway pressure (BPAP) devices, and continuous positive airway pressure (CPAP) devices. Key messages • In patients with COPD, home NIPPV as delivered by a BPAP device (compared to no device) was associated with lower mortality, intubations, hospital admissions, but no change in quality of life (low to moderate SOE). NIPPV as delivered by a HMV device (compared individually with BPAP, CPAP, or no device) was associated with fewer hospital admissions (low SOE). In patients with thoracic restrictive diseases, HMV (compared to no device) was associated with lower mortality (low SOE).

    Amyotrophic lateral sclerosis (ALS) is a devastating motor neuron disease causing progressive paralysis and eventual death, usually from respiratory failure.
