Clinical Trial Summary

Regarding the postoperative care strategies following elective craniotomy procedures there is little evidence. Many neurosurgical departments prefer these patients to remain intubated and sedated for many hours postoperatively to minimize hemodynamic and respiratory distress in fear of early postoperative complications such as rebleeding or seizures. In this prospective observational study the investigators aim to show that early tracheal extubation following elective brain surgery is feasible and safe.


Clinical Trial Description

Background Amongst many surgical subspecialties particularly the field of neurosurgery has made major advancements in the last decade in regards to microsurgical techniques such as continuously pushing the boundaries of radical tumor resection while ensuring patient security and functional integrity nonetheless to mention just one aspect. However, once the surgeon has closed up and the patient is transferred to the intensive care or intermediate care unit for observation for the crucial early postoperative hours the brain tissue is exposed to hemodynamic and respirational changes. Early postoperative bleeding and brain swelling are the most feared complications after elective craniotomy in neurosurgery. Unfortunately, there is no bedside monitoring to diagnose these complications at a very early state. Patients become symptomatic by a clinical neurological deterioration or an early postoperative seizure. Therefore, much attention has been paid to provide a close monitoring and observation of the patient usually at a critical care unit during the first hours after brain surgery. Although not substantiated by hard evidence, the major postoperative strategies are the following: 1. Parameter oriented: Periods of arterial hypertension, hypoventilation with arterial CO2 increase, low oxygen saturation, extensive coughing, pressing, and pain are strictly avoided. In order to achieve this goal the patient remains intubated and sedated during the first hours postoperatively. 2. Symptom oriented: The awakened patient is monitored clinically as early as possible for a deterioration of consciousness, seizure or the development of a new neurological deficit. Thus, the patient is extubated in a timely fashion postoperatively. Evidently, both strategies are opposite to each other, since strategy 1 requires keeping the patient sedated and intubated over a longer period of time and weaning from artificial ventilation is performed at the critical care unit. This hinders early diagnosis of a neurological deterioration and timely action. On the contrary, strategy 2 aims at a very early extubation of the patient immediately after completing the surgical procedure, which exposes the patient to more hemodynamic and cardiopulmonary stress which may lead to a higher likelihood of a secondary neurological injury. Since, to the best of the investigators' knowledge, there is no prospective data, depending on the philosophy of the neurosurgeon, the anesthetist and the neuro-intensivist one strategy is preferred over another. For this clinical study, the Department of Neurosurgery Berne is conducting a prospective observational study to show that early tracheal extubation following elective brain surgery is feasible and safe. Objective The investigators aim to provide prospective data with respect to complications of early extubation and to compare these results to existing data in the literature with the delayed extubation strategy after elective craniotomy. The investigators believe early extubation and continuous clinical monitoring does not coincide with a higher rate of postoperative complications. Furthermore, strategy 2 might even be superior to strategy 1 in that respect. Also, by conducting this clinical trial the investigators hope to get a more profound insight to further improve the postoperative patient management after elective brain surgery. The primary endpoint is the incidence of significant postoperative intracranial hemorrhage, brain swelling or seizure leading to either surgical intervention or any new, secondary neurological deficit, coma, palliative care or death related to postoperative events. As a secondary endpoint the investigators will assess the role of routine early postoperative CT imaging before transfer to the ward and surgical drains. Methods This clinical study is designed as a prospective monocenter observational trial. Data as defined in a case report form will be collected of patients undergoing elective craniotomy at the departments of neurosurgery of the University Hospitals in Bern. Patient data collection begins at admission and ends at hospital discharge except for a mortality follow-up of 30 days postoperatively. Statistical analysis will be performed as defined in the study protocol. ;
