| Scientific title | Study of the effectiveness of craniotomy (Decompressive Craniectomy [DC] or routine temporoparietal craniectomy) on patients with Acute post-traumatic Brain Swelling after severe traumatic brain injury: a single-centre, prospective randomised, controlled, double-blind trial |
| Study acronym | DCABS |
| Study objectives | The aim of the present clinical study was to assess the efficacy of craniotomy, decompressive craniectomy (DC) or routine temporoparietal craniectomy, on patients with acute post-traumatic brain swelling (BS). We assume that DC has superior effectiveness on patients with acute BS after severe traumatic brain injury. |
| Ethics approval(s) | Institutional Review Board and the ethical committees of Clinical Medical College of Hangzhou gave approval on the 1st September 2002 (ref: 200203) |
| Health condition(s) or problem(s) studied | Acute post-traumatic brain swelling |
| Intervention | Based on the guidelines for the management of severe head injury set forth by the Joint Section on Neurotrauma and Critical Care of the Brain Trauma Foundation and the American Association of Neurological Surgeons, all patients underwent lateral craniotomy within 24 hours after injury and other medical management such as dehydration with mannitol (average amount received in subsequent 6-hour period was 20% mannitol 125 ml) and routine pharmacological or physical measures adopted to maintain normal body temperature after diagnosis of post-traumatic BS accordingly. The surgery mode of DC was elective at the frontoparietotemporal region, based on the lesion location and midline shift determined by CT scans. Briefly, the bone window was about 15 cm in diameter with duraplasty using expanded dura substitute when necessary. The anterior was frontal to the midpupillary lines, and the posterior line was about 3 - 4 cm posterior to the external acustic meatus. The superior line was 2 cm of the lateral edge of the superior sagittal sinus, and the inferior line was extended below the level of the zygomatic arch, so that the frontal and temporal base could be explored. Durotomy was performed over the entire region of bony decompression as a stellate shape. Cranioplasty was performed after 3 months. Post-operative therapy was similar with those previously described, which included keeping respiratory tract unobstructed (with assisted ventilation to ensure arterial O2 saturation (SaO2) greater than or equal to 95% against hypoxia and partial pressure of carbon dioxide in arterial blood (PaCO2) maintained near 40mm Hg at 37°C), intubations if necessary, controlling the blood glucose level and body temperature and balancing water and electrolyte, dehydration and diuresis, homeostasis balanced, anti-infection with sensitive antibiotics and so on. The control group received the unilateral routine temporoparietal craniectomy and the operation site depended on the location of injury and midline shift accordingly. The bone window diametered about 8 cm and the dura mater was also fixed at the edge with duraplasty, and the bone was re-implanted after 3 - 6 months. In the routine craniotomy group, post-operative treatment was similar with those in the DC group. |
| Intervention type | Other |
| Primary outcome measure | 1. Intracranial pressure (ICP) - continuous recording of ICP was applied in all patients for 96 hours with the ICP monitor system (Camino-MPM1, Integra LifeSciences CO, USA). A cranial hole was drilled, if necessary, and the drainage catheter was induced 5 cm or so into right lateral ventricles via the level of the anterior horn. The intraventricular (intracerebral) pressure probe (Camino-110-4B) was placed at the level of foramen of Momro during craniotomy. 2. Glasgow Outcome Scale (GOS) scores, from 1 to 5 respectively, according to: death, vegetable state, severe disability, moderate disability, mild or no disability, evaluated at 1 years follow-up after injury |
| Secondary outcome measures | 1. Vital signs (temperature, heart rate, breathing rate and blood pressure), arterial oxygen saturation with the multiple monitor (Model NO: 90309, Space Lab, Medical. Inc. USA) recorded every 12 hours for 7 days after craniotomy 2. Complications, mainly inclusive of delayed intracranial haematoma, pulmonary infection, digestive tract haemorrhage, and electrolytes disorders (beyond the normal serum concentrations of Na+, Cl-, Mg2+, K+, P3+ and Ca2+), recorded every 12 hours for 7 days, 24 hours for another 7 days after craniotomy |
