The Paracetamol AfteR Traumatic Brain InjurY Study

Overview

This primary aim is to investigate the effect of paracetamol in reducing body temperature in patients who have sustained traumatic brain injury. This study is also investigating the safety of paracetamol in this patient population.

Traumatic head injury is a bruising of areas of the brain that occurs commonly as a result of a fall or a motor vehicle accident. Unfortunately, this is a common global occurrence and it occurs both in developing and developed countries. It causes death in nearly 1 in 3 of those who are most severely affected and a large proportion of those that survive have long-term physical or mental disability. Hence, traumatic head injury is a major global problem. At present there are very few therapies that are known to be effective after a traumatic head injury. In particular the investigators are uncertain about whether modifying body temperature has any effect (good or bad) on the outcomes of patients. Although, this is practiced by some intensive care units around the world. The investigators have searched extensively to look for any evidence that altering body temperature after traumatic head injury improves the outcome of patients (by reducing the amount of death or disability) and were unable to find any evidence at all. Some preliminary research in both animal experiments and clinical studies suggest that a raised temperature after forms of brain injury may in fact be harmful. Therefore, at present the investigators believe that we do not really know what effect changing body temperature after head injury has on the outcome of patients. The investigators are proposing to conduct a clinical study of patients who have had a severe head injury. The patients will be randomly allocated to 2 groups who will get either regular Paracetamol (dissolved in fluid) or a bottle of fluid without any Paracetamol. The 2 treatments will look identical and neither the patients nor the health care workers will know what treatment they are getting. Doing the study in this way will allow us to work out whether giving Paracetamol reduces the temperature of the body and whether there are any side effects that occur. If the study shows that Paracetamol can reduce body temperature safely in this setting then the investigators will work towards doing a larger study of treatments that reduce body temperature. The purpose of this larger study would be to see if the investigators can, not only reduce body temperature but also reduce amount of disability (physical and mental) as well as the death rate in traumatically brain injured patients. In the proposed study the investigators will be using a higher dose of Paracetamol that is usually prescribed. Other research has shown that the dose that the investigators are proposing to use is safe and also that smaller doses in fact do not reduce body temperature.
