A Survey On Fever Monitoring and Management in Patients With Acute Brain Injury: The SUMMA Study.
Fever is common in patients with acute brain injury and worsens secondary brain injury and clinical outcomes. Currently, there is a lack of consensus on the definition of fever and its management. The aims of the survey were to explore: (a) fever definitions, (b) thresholds to trigger temperature management, and (c) therapeutic strategies to control fever. ⋯ In this survey we identified substantial variability in fever definition and application of temperature management in acute brain injury patients. These findings may be helpful in promoting educational interventions and in designing future studies on this topic.

The α2-adrenergic receptor agonist dexmedetomidine has sedative, anxiolytic, analgesic, and sympatholytic effects. The potential advantages of neuroprotection, minimal impact on neuronal function, stable hemodynamics, opioid and anesthesia sparing effects, and minimal respiratory depression during awake procedures render it an effective anesthetic adjuvant in various neurosurgical settings. However, both the benefits and drawbacks of the use dexmedetomidine in neuroanesthesia should be considered. This narrative review will summarize the applications of dexmedetomidine in various neurosurgical settings, highlighting evidence regarding both its common and controversial uses.

Preoperative Gabapentin Administration Improves Acute Postoperative Analgesia in Patients Undergoing Craniotomy: A Randomized Controlled Trial.
Gabapentin is an adjuvant antiepileptic agent and helps to reduce acute postoperative pain in several surgery settings. However, the effect of gabapentin on postoperative pain from suboccipital or subtemporal craniotomy is not clear. ⋯ Preoperative gabapentin significantly alleviated acute postoperative pain and decreased the incidence of vomiting in patients undergoing suboccipital or subtemporal craniotomy. However, more attention should be paid to early postoperative sedation when multimodal analgesia with gabapentin is administered.

Portable Infrared Pupillometer in Patients With Subarachnoid Hemorrhage: Prognostic Value and Circadian Rhythm of the Neurological Pupil Index (NPi).
Portable automated infrared pupillometry is becoming increasingly popular. To generate an objective reference base, the Neurological Pupil index (NPi) which combines different values of the pupillary light reflex is being introduced into clinical practice. In this explorative study, we examined different aspects of the NPi in relation to clinical severity and outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). ⋯ On the basis of this preliminary study, the assessment of NPi by pupillometry is feasible and might complement multimodal neuromonitoring in patients with aSAH.
