The proceedings of this conference were recently published.Central to the debate around the performance of DC is the issue of what constitutes acceptable (or “good”) neurological recovery. Severe head injury can trigger brain swelling, thereby increasing pressure on the brain (raised intracranial pressure, ICP). Traumatic brain injury is a major cause of premature death and disability. Any opinions, findings, and conclusions, or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the US Army Contracting Command, Aberdeen Proving Ground, Natick Contracting Division, or Stanford University. Hypocapnia can be intentional to treat intracranial hypertension or unintentional due to a spontaneous hyperventilation (SHV). It is well known that carbon dioxide (CO2) is a powerful modulator of cerebral vasomotor tone, and hypocapnialeads to cerebral vasoconstriction, whereas hypercapnia causes cerebral vasodilation.

Given the controversy surrounding DC and the uncertainty about which patients will return to prior or meaningful function and which will not, family members or other proxy decision-makers familiar with patients’ values and preferences should be provided with the best information available and included in clinical decision making.Though convincing evidence currently supports that DC reduces ICP, and that DC of insufficient size is associated with poor outcomes, additional high-quality studies are needed to inform every aspect of DC as it is applied in clinical practice for severe TBI. However, this procedure has been demonstrated to reduce ICP and to minimize days in the intensive care unit (ICU).A large frontotemporoparietal DC (not less than 12 × 15 cm or 15 cm diameter) is recommended over a small frontotemporoparietal DC for reduced mortality and improved neurologic outcomes in patients with severe TBI.”The first recommendation was based on the 6-mo outcomes from DECRA.By virtue of the updated body of evidence, including 12-mo outcome data from DECRA and RESCUEicp, both published subsequent to the 2017 guidelines, we have removed the first recommendation and restated the second. Perhaps the most important conclusion of these studies is that choosing to perform a DC is not a simple decision and that the potential benefits should be balanced against the complications and likely outcomes on a case-by-case basis.Anecdotal evidence suggests that these new RCTs have not markedly changed practice. Both RCTs that compared DC to initial medical management were rated class 1.Summary of Evidence – Class 1 and 2 Studies of Decompressive CraniectomySummary of Evidence – Class 1 and 2 Studies of Decompressive CraniectomyFundamental to this update was an appraisal of the level of evidence provided by both the DECRA and the RESCUEicp RCTs. (3) They dichotomized the 8-item GOS-E scale to calculate the odds of unfavorable outcomes.Using group differences assessed at 6 mo postenrollment–the primary outcome–they found the DC group had lower ICP, fewer days on mechanical ventilation and in the ICU, and no difference between groups for mortality.

Enhanced Recovery After Surgery Reduces Postoperative Opioid Use and 90-Day Readmission Rates After Open Thoracolumbar Fusion for Adult Degenerative Deformity Treatment to lower people's ICP commonly involves hyperventilation therapy (increasing blood oxygen levels) following the brain injury. matic brain injury (TBI), hyperventilation became a cornerstone in the management of TBI and has remained so for decades. A paucity of literature currently informs primary DC, or the practice of leaving the bone flap off following an initial surgery to evacuate an intracranial mass lesion.

At 12 mo, there was a trend to worse functional outcomes in the craniectomy group (OR 1.68, 95% CI 0.96-2.93; RESCUEicp compared outcomes of patients who received DC as a salvage treatment for ICP elevation with those who received medical management. Hyperventilation alone, as well as in conjunction with a buffer (THAM [tris‐hydroxy‐methyl‐amino methane]), showed a beneficial effect on mortality at one year after injury, although the effect measure was imprecise (RR 0.73; 95% CI 0.36 to 1.49, and RR 0.89; 95% CI 0.47 to 1.72 respectively). Using the median score for each group of the GOS-E measured at 6 mo postinjury (3: DC, 4: No DC), the unadjusted odds ratio (OR) for worse outcomes in the DC group was 1.84 (95% CI 1.05-3.24), More recently, the DECRA investigators published the 12-mo outcome data from their study. 0.87 ( 95 % CI 0.58 to 1.28 ) CI ) were calculated for each trial an...
