Hyperventilation Therapy for Control of Posttraumatic Intracranial Hypertension

During traumatic brain injury, intracranial hypertension (ICH) can become a life-threatening condition if it is not managed quickly and adequately. Physicians use therapeutic hyperventilation to reduce elevated intracranial pressure (ICP) by manipulating autoregulatory functions connected to cerebrovascular CO2 reactivity. Inducing hypocapnia via hyperventilation reduces the partial pressure of arterial carbon dioxide (PaCO2), which incites vasoconstriction in the cerebral resistance arterioles. This constriction decrease cerebral blood flow, which reduces cerebral blood volume and, ultimately, decreases the patient’s ICP. The effects of therapeutic hyperventilation (HV) are transient, but the risks accompanying these changes in cerebral and systemic physiology must be carefully considered before the treatment can be deemed advisable. The most prominent criticism of this approach is the cited possibility of developing cerebral ischemia and tissue hypoxia. While it is true that certain measures, such as cerebral oxygenation monitoring, are needed to mitigate these dangerous conditions, using available evidence of potential poor outcomes associated with HV as justification to dismiss the implementation of therapeutic HV is debatable and remains a controversial subject among physicians. This review highlights various issues surrounding the use of HV as a means of controlling posttraumatic ICH, including indications for treatment, potential risks, and benefits, and a discussion of what techniques can be implemented to avoid adverse complications.Peer reviewe

Consenso internacional sobre la monitorización de la presión tisular cerebral de oxígeno en pacientes neurocríticos

[ES] La monitorización continua de la oxigenación cerebral y su aplicación al manejo del paciente neurológico grave es uno de los grandes retos actuales de la medicina crítica. Aunque han sido descritas diversas técnicas para la monitorización de la oxigenación cerebral, la monitorización tisular cerebral de oxígeno proporciona una relevante información sobre los niveles de oxígeno a nivel del tejido cerebral. Su desarrollo se ha asociado a la necesidad de responder no solamente aspectos técnicos sobre la misma, sino también al significado de la alteración de los valores de la oxigenación cerebral en el paciente neurocrítico. El documento de consenso da respuesta a diversas cuestiones relativas a la monitorización de la oxigenación cerebral mediante sensor de presión tisular cerebral de oxígeno. Para ello se elaboró un panel de preguntas y se realizó una revisión de la literatura médica, y evaluando la calidad de la evidencia y el nivel de recomendación mediante la metodología GRADE.[EN] Continuous monitoring of cerebral oxygenation and its application to the management of the severe neurological patient is a challenge for the management of patients with acute critical brain damage. Although several techniques have been described for monitoring brain, brain tissue oxygen monitoring provides relevant information about oxygen levels of brain tissue. However, the development of this technique has been associated with the need to answer not only some technical aspects of it as well as the meaning of the changes of the cerebral oxygenation in the neurocritical patient. The consensus document responds to various questions related to the monitoring of cerebral oxygenation by means of a cerebral oxygen tissue pressure sensor. For this purpose, a list of questions was prepared and a reviewed of the medical literature was made. The quality of the evidence and the degree of recommendation was evaluated using the GRADE methodology
