In 1987, the nation's pediatrics authorities tried to standardize the diagnosis, listing 14 different criteria to confirm brain death, like the absence of reflexes, and requiring, under certain conditions, additional X-rays and tests for brain-wave activity.
The adequate depth of anesthesia during the surgical period was evaluated with maintenance of physiological variables (heart rate and arterial pressure) and absence of reflexes (corneal and hind limb flexion response), as well as unresponsiveness to stimuli during manipulation.
Anesthesia levels were monitored by the recording of low-frequency electroencephalogram (EEG) and the absence of reflexes.
In the absence of reflexes which change Csp, the elastic recoil pressure is constant at constant Vs, but when Pab increases and blood flows out of the splanchnic bed, Vs and the elastic recoil pressure both decrease.
Adequacy of anaesthesia was determined by end tidal agent monitoring, the absence of movement, haemodynamic monitoring (heart rate and arterial pressure), and absence of reflexes.
Adequate anaesthesia was assured by the absence of reflexes prior to rapid cervical dislocation and tissues processed for real-time RT PCR, immunohistochemistry, and western blot analyses of JAM-A (see Supplementary material online for details).
However, we do not exclude the possibility that the absence of pupillary reflex is associated with poor outcomes.
Clinical signs of brain death included the absence of corneal reflex and the absence of coughing in response to tracheal suctioning.
The absence of this reflex in the diffraction patterns of calcined powders indicates the disordering of organized structure in the process of crystallization of titanium dioxide.
The occurrence of mydriasis in OM is considered as secondary to a functional exhaustion of parasympathetic fibers running within the third cranial nerve, with absence of light reflex [14].
