TI  - Pressure Autoregulation Measurement Techniques in Adult Traumatic Brain Injury, 
      Part II: A Scoping Review of Continuous Methods.

AB  - A scoping review of the literature was performed systematically on commonly 
      described continuous autoregulation measurement techniques in adult traumatic 
      brain injury (TBI) to provide an overview of methodology and comprehensive 
      reference library of the available literature for each technique. Five separate 
      small systematic reviews were conducted for each of the continuous techniques: 
      pressure reactivity index (PRx), laser Doppler flowmetry (LDF), near infrared 
      spectroscopy (NIRS) techniques, brain tissue oxygen tension (PbtO(2)), and 
      thermal diffusion (TD) techniques. Articles from MEDLINE, BIOSIS, EMBASE, Global 
      Health, Scopus, Cochrane Library (inception to December 2016), and reference 
      lists of relevant articles were searched. A two-tier filter of references was 
      conducted. The literature base identified from the individual searches was 
      limited, except for PRx. The total number of articles using each of the five 
      searched techniques for continuous autoregulation in adult TBI were: PRx (28), 
      LDF (4), NIRS (9), PbtO(2) (10), and TD (8). All continuous techniques described 
      in adult TBI are based on moving correlation coefficients. The premise behind the 
      calculation of these moving correlation coefficients focuses on the impact of 
      slow fluctuations in either mean arterial pressure (MAP) or cerebral perfusion 
      pressure (CPP) on some indirect measure of cerebral blood flow (CBF), such as: 
      intracranial pressure (ICP), LDF, NIRS signals, PbtO(2), or TD CBF. The thought 
      is the correlation between a hemodynamic driving factor, such as MAP or CPP, and 
      a surrogate for CBF or cerebral perfusion sheds insight on the state of cerebral 
      autoregulation. Both PRx and NIRS indices were validated experimentally against 
      the "gold standard" static autoregulatory curve (Lassen curve) at least around 
      the lower threshold of autoregulation. The PRx has the largest literature base 
      supporting the association with patient outcome. Various methods of continuous 
      autoregulation assessment are described within the adult TBI literature. Many 
      studies exist on these various indices, suggesting an association between their 
      values and patient morbidity/death.
