The Impact of Bispectral Index Monitoring on Sedation Administration in Mechanically Ventilated Patients

This prospective randomised controlled trial was designed to assess the effectiveness of the Bispectral Index Sedation (BIS) monitor in supporting clinical, sedation management decisions in mechanically ventilated ICU patients. The primary hypothesis for the study is that patients with Bispectral Index Sedation (BIS) monitoring will receive less sedation then those receiving standard sedation management. The secondary hypotheses are: 1. Patients with BIS have fewer ventilation days than those receiving standard sedation management. 2. Level of sedation administered will differ according to the critical care experience and qualification of the nurse.
