Study summary

This study will try to evaluate the effectiveness and safety of a new method for achieving mild hypothermia, i.e.,mild hypothermia therapy through rectum. Half of participants will be treated by the widely-used hyper-hypothermia blanket method, while the other half will be treated by the investigators' new method.

Read the detailed description

Mild hypothermia therapy has been proved to be beneficial to patients with severe traumatic brain injury. Currently a variety of cooling methods can achieve mild hypothermia,the hyper-hypothermia blanket being the most widely-used one.

Hyper-hypothermia blanket is a waterbed mattress connected to a thermostat-controlled water tank. Water is cooled in the tank and recycled between the tank and the mattress so that the patients sleeping on the mattress can be stably cooled. The operation is basically program-controlled ,but the whole system is quite expensive.

The investigators came up with a new cooling system which is very simple and accessible. A condom inserted with two 10# gastric tube and one 6# gastric tube and ringed with a rubber band is inserted into the patient's rectum, and ice-cold saline is pumped in through one 10# gastric tube and drained out from the other 10# gastric tube, the 6# gastric tube connected to the pressure monitor. Cooling rate is controlled by the flow speed of cold saline. The investigators will evaluate the effectiveness and safety of this new method for achieving mild hypothermia.

Study arms

  • Experimental
    Rectum cooling system

    Insert the self-made device into the patient's rectum, pump ice-cold saline in to induce mild hypothermia, sustain the desired temperature for 12 hours,then let the body rewarm slowly. Body temperature changes are achieved by controlling the pumping speed of saline.

    Device: Rectum cooling system

  • Active comparator
    Hyper-hypothermia blanket

    Let the patient sleep on the hyper-hypothermia blanket, set the target temperature to induce mild hypothermia, sustain the desired temperature for 12 hours,then let the body rewarm slowly. Body temperature changes are achieved by adjusting the target temperature of the device accordingly.

    Device: Hyper-hypothermia blanket

What researchers measure

Primary outcomes

  1. Rate of Cooling

    The body temperature is measured every 15 minutes until the target temperature(33-35℃)is reached.

    Time frame: 4 hours

  2. Body Temperature Fluctuations in Maintenance Phase

    During the maintenance phase,the body temperature is measured every 15 minutes.

    Time frame: 12 hours

  3. Rate of Rewarming

    The body temperature is measured every 15 minutes until it rises to 36.5℃.

    Time frame: 24 to 48 hours

Secondary outcomes

  1. Incidence of Complications

    Any occurence of shiver,arrhythmia and coagulation abnormalities during the therapy.

    Time frame: 24 to 72 hours

  2. Fecal Occult Blood Testing Results Before and After the Therapy

    Time frame: Within 24 hours before the therapy and 48 to 72 hours after the therapy
