Association of Low Blood Pressure, Low Bispectral Index and Low Minimum Alveolar Concentration of Anaesthetic during Surgery with Postoperative 30-day Mortality: A Systemic Review and Meta-Analysis

The triple low state [low mean arterial pressure, low bispectral index (BIS) and a low minimum alveolar concentration (MAC)] fraction of anaesthetic during surgery) has been a controversial subject of interest in clinical practise.
