Effects Of Ward Environment Factors On Intracranial Pressure And Cerebral Perfusion Pressure In Patients With Craniocerebral Injury

Objectives: To observe the effects of four environmental factors such as noise,light,temperature and humidity in the ward on intracranial pressure and cerebral perfusion pressure in patients with traumatic brain injury,to explore its influence mechanism,and to verify whether the ward environment has any effect on intracranial pressure and cerebral perfusion.How to influence.And to find the most favorable ward environment that can maintain the intracranial pressure and cerebral perfusion pressure relatively stable and can synergistically reduce intracranial hypertension and stabilize cerebral perfusion pressure.Methods: A prospective controlled study was used.54 patients with traumatic brain injury who underwent intracranial pressure monitoring in the ICU of Fuyang City People's Hospital from January 2018 to March 2019 were randomly divided into four groups;the noise group,the light group and the humidity group were taken separately.The three intervention measures of noise reduction,radiation reduction and humidification were compared with the corresponding control group.The temperature group was studied by means of different time periods at different room temperature before and after self-control.All groups were observed changes in intracranial pressure(ICP)and cerebral perfusion pressure(CPP)in patients with craniocerebral injury in different ward environments.Results: 1.In the noise group,the noise reduction group(wearing earplugs,noise reduction 32dB)and the control group were significantly decreased after 24 h,the difference was statistically significant(P=0.038);while the CPP of the two groups was slightly elevated.,but the difference was not statistically significant(P=0.634).2.There was no significant difference in the ICP of patients in the temperature group when the temperature was slightly higher than that in the afternoon at low temperature(P=0.151).The difference of CPP in the morning was slightly lower than that in the afternoon.The difference was not statistically significant(P =0.589).3.In the humidity group,the humidification group(humidifier humidification,relative humidity before nasal maintenance was maintained at 80-100%)and the ICP were significantly decreased after 24 h in the control group,and the decrease in the Shengwei group was greater than that in the control group.The significance of learning(P = 0.047);and the CPP of the two groups were slightly elevated,but the difference was not statistically significant(P = 0.101).4.In the light group,the illuminating group(with eye mask,light intensity of 0Lux)and the control group showed significant decrease in ICP after 24 h,the difference was not statistically significant(P=0.091);while the CPP of the two groups was slightly elevated.The difference was not statistically significant(P = 0.135).Conclusions: 1.Reduce the environmental noise of the ICU ward,help to reduce the ICP of patients with craniocerebral injury,and maintain the stability of CPP.Therefore,attention should be paid to the control of noise,and a series of noise reduction measures are taken to keep the noise within the range recommended by the WHO.2.When the room temperature of the ICU ward fluctuated within the specified range of 24±1.5?,there was no significant change in ICP and CPP in patients with craniocerebral injury.Therefore,maintaining the room temperature of the intensive care unit in the range of 24 ± 1.5 ? is important for the stabilization of ICP and CPP in patients with craniocerebral injury.3.Improve the relative humidity of inhaled air in patients with non-mechanical ventilation of craniocerebral injury,which is beneficial to reduce intracranial pressure and increase cerebral perfusion pressure.Therefore,in the nursing work,attention should be paid to the change of humidity in the ICU ward,and the relative humidity of the air entering the airway is improved,which is conducive to the recovery of the condition of the brain injury patients.4.Reduce the light intensity entering the patient's fundus,the impact of ICP and CPP on patients with craniocerebral injury is not significant,but still need to control the light intensity of the ICU ward,giving patients a comfortable hospital environment.
