International consensus on the monitoring of cerebral oxygen tissue pressure in neurocritical patients. / Consenso internacional sobre la monitorización de la presión tisular cerebral de oxígeno en pacientes neurocríticos.

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.

Programmable pump for the administration of morphine in the cisterna magna. A new approach.

The implantation of a drug (opioid) infusion system catheter at the level of the cisterna magna, connected to an implanted programmable pump (Synchromed pump, 8611-H, Medtronic, Minneapolis, MN) is the procedure we use most commonly for the treatment of craniofacial and upper cervical pain. Our implantation technique, which we consider simple and easy to perform, is discussed in this article. Our results have been extremely encouraging, without untoward effects occurring. Adverse effects are prevented by the close proximity of the catheter tip to the pain receptors.
