Background and study aims
Patients who are having intracranial surgery (opening the skull) to treat a haematoma (bleeding on the brain) need to have a tube inserted into their airway to enable mechanical ventilation (a breathing machine) to ensure they get enough air during the operation. The patient must be sedated to some extent because the tube and mechanical ventilation is uncomfortable and potentially distressing. After surgery, patients who are still being mechanically ventilated must be cared for in the intensive care unit (ICU), where they are at higher risk of picking up an infection or suffering damage to the lungs from the mechanical ventilation. In addition, it is difficult to assess the patient's brain function when they are sedated. This trial aims to compare whether it is better to extubate (remove the breathing tube) in the operating theatre after the operation or to extubate in the ICU 8 hours after the operation and care for the patient in a post-surgical ward.
Who can participate?
Adults who need to have surgery to open their skull to remove blood that is pressing on their brain and who have not had a breathing tube inserted before the operation.
What does the study involve?
Participants were randomly allocated to one of two groups. Both groups had surgery to treat their haematoma as usual. One group were woken from anaesthesia and had the breathing tube removed in the operating theatre. Participants in the other group were taken to the ICU while still anaesthetised and had the breathing tube removed 8 hours after the end of the surgery.
What are the possible benefits and risks of participating?
Participants who were in the early extubation group might experience fewer complications of mechanical ventilation and not need to be admitted to the ICU.

| Scientific title | Fast-track extubation in patients after intracranial hematoma surgery |
| Study acronym | FTEIHS |
| Study objectives | Fast track should be regarded as a routine technique in patients who meet the required criteria, so that they may be discharged faster and with fewer complications that may potentially endanger their lives or prolong their hospital stay. Deliberate delay or failed extubation increases the incidence of post-operative pneumonia, mortality and longer stays in the ICU and hospital. Another important issue, after considering the patient’s life and safety first, is the economic factor. If the patient is discharged without admission to the ICU, the economic burden for the patient, the hospital or the medical insurance company is significantly reduced. This study aims to determine whether Intensive Care Unit stay and ventilator-associated complications are reduced in patients who received surgery for intracranial hematoma if they are extubated early. |

| Health condition(s) or problem(s) studied | Early extubation to prevent ventilator-associated complications following intracranial hematoma surgery |
| Intervention | Early extubation, also known as fast track, is desirable after intracranial hematoma surgery to avoid ventilator-associated complications associated with admission to an intensive care unit (ICU). The objective of the present study was to determine whether ICU stay and ventilator-associated complications are reduced in patients who received surgery for intracranial hematoma if they are extubated early. A total of 17 patients were randomly assigned to two groups: In Group 1, patients were extubated early or using the fast-track method Those in Group 2 were transferred to the ICU and extubated at 8 h post-operatively. Patients programmed to receive a cranial surgery were invited to participate into this trial. Patients from the two groups were assessed on admission to the operating room according to established standards and general anesthesia was induced with propofol (2 mg/kg) and fentanyl (2 µg/kg). Extubation time and hemodynamic stability (number of anesthetic adjustments required to maintain hemodynamic parameters within 20% of the predicted values) were assessed post-operatively. Patients were extubated when the following criteria were fulfilled: Regular breathing, without intercostal retraction and with a respiratory rate of >8 BPM, a telespiratory CO2 pressure of 95% with an inspired oxygen fraction of 100%, presence of a swallowing reflex, hemodynamic stability (a change in baseline blood pressure of ≤15 mm Hg), and a cooperative and oriented patient able to respond to verbal instructions. Attempted fast-track extubation was performed after post-operative neurological assessment by the same responsible surgeon. The difference between the two groups was in extubation time criteria; extubation was 8 h after surgery in the conventional group, but extubation was immediately post-surgical in the fast-track group. |
