| Scientific title | Application of Multiple Cerebral Monitoring Severe Traumatic Brain Injury: a multicentre study |
| Study acronym | AMCMSTBI |
| Study objectives | Significant reduction in mortality and morbidity can be achieved by using intensive management protocols. Compared to early studies of 50% mortality, the results of efforts in investigating the proper procedures among each stages, reveals a reduction of mortality rate to average of 36% among severe head injured patients. Kiening et al. reported that the elevation of the Cerebral Perfusion Pressure (CPP) from 32 to 67 mmHg improved cerebral tissue oxygenation (PtO2) by 62%. Recent studies also showed that the mortality significantly decreased in the group of PtO2 of monitoring. However, there are still debates about the optimal CPP, especially in the patient with impaired pressure autoregulation. Nevertheless, optimal Inter-Cranial Pressure (ICP) and CPP management may not always prevent cerebral ischaemia, which adversely influences patient outcome. The aims of this study are: 1. To evaluate the efficacy of multiple cerebral monitoring 2. To find the optimal CPP in different groups with autoregulation in the treatment of Severe Traumatic Brain Injury (STBI) 3. To investigate the outcome difference (Glasgow Outcome Score [GOS], Glasgow Outcome Score Extended [GOSE], survival analysis and Health-related Quality Of Life [HQOL]) among patients with different monitoring groups |

| Intervention | The hospitals included in this series were Wan Fang Hospital, Veterans General Hospital, Taipei, National Taiwan University Hospital, Mackay Memorial Hospital, Shin Kong Wu Ho-Su Memorial Hospital and Taipei Tri-Service General Hospital. Twenty to thirty patients are provided from each medical centre. All the subjects are randomised (block in four) and divided in to the study group (Group A) or control group (Group B): Group A: multiple cerebral monitoring systems, ICP, PtO2 and the TransCranial Doppler (TCD74) Group B: ICP monitoring only The major differences between the Group A and Group B are the treatment goals. In the Group A, PtO2 of at least 25 - 30 mmHg is maintained, by the adjustment of CPP. In Group B, Mean Arterial Pressure (MAP) was kept at 90 mmHg or more and CPP was maintained at a minimum of 60 - 70 mmHg. Cerebral monitoring: 1. The TransCranial Doppler (TCD) insonation was performed using a 2 MHz real time and pulse-Doppler transducer. For continuous monitoring, the 2 MHz probe was applied at a temporal window with a fixed head holder (Spenser Marco 600) connected to the TCD monitor (Nicolet/EME Companion II, Germany) to detect the Middle Cerebral Artery (MCA) at the depth of 55 - 65 cm and to record the Mean Flow Velocity (MFV) 2. An intraparenchymal ICP monitor (Codman electrode MicroSensor, Johnson & Johnson Medical, Ltd., USA) was used for monitoring the ICP. The ICP monitor was connected to a Hewlett Packard (HP) monitor, model 66s-M116A, via a pressure transducer (Codman neuromonitor interface control unit, 82-6605) and module 3. An intraparenchymal brain tissue combined Oxygen and Temperature probe (LICOX REFIT2, Integra NeuroSciences, Ltd., England) was used for monitoring the PtO2. The PtO2 probe monitor is placed in the healthy side of brain parenchyma. The signals are transmitted to a HP monitor, via a transducer box (LICOX REF POM.BOX, Integra NeuroSciences, Ltd., England) and monitor cable (LICOX REF NL950-MC-01, Integra NeuroSciences, Ltd., England) Standard management: In the intensive care unit, patients were positioned in bed with an approximately 30° head up. Monitoring involved in simultaneous and continuous assessment of MAP from a radial or brachial arterial line, electrocardiogram, pulse oximetry values, and End-tidal Carbon Dioxide (EtCO2) by capnography. Central venous pressure and body temperature were assessed either continuously or intermittently at frequent intervals. Routine pharmacological or physical measures were adopted to avoid fever if body temperature levels were 37.5°C or higher. Mechanical ventilation was adjusted to keep EtCO2 between 30 and 33 mmHg. Sedation with propofol titration is used for ICP control. Patients underwent complete neurological assessment by nursing staff hourly or more frequently if the condition was deteriorating. |
| Intervention type | Other |
| Primary outcome measure | 1. Application of multiple cerebral blood monitor in the treatment of STBI could result in reduced mortality rate and impaired quality of life 2. Patients with impaired autoregulation, the optimal CPP value could be changed |
| Secondary outcome measures | 1.Through this study, the result could be contributed to the establishment of a new Clinical Practice Guideline of STBI 2. The result could be used as a guideline to train young physicians 3. In different groups, patients with multiple cerebral monitoring will have better GOS, GOSE, HRQL, and survival |
