Early abolition of cough reflex predicts mortality in deeply sedated brain-injured patients.

Background: Deep sedation may hamper the detection of neurological deterioration in brain-injured patients. Impaired brainstem reflexes within the first 24 h of deep sedation are associated with increased mortality in non-brain-injured patients. Our objective was to confirm this association in brain-injured patients.

Mismatch negativity to predict subsequent awakening in deeply sedated critically ill patients.

Background: Mismatch negativity (MMN) is the neurophysiological correlate of cognitive integration of novel stimuli. Although MMN is a well-established predictor of awakening in non-sedated comatose patients, its prognostic value in deeply sedated critically ill patients remains unknown. The aim of this prospective, observational pilot study was to investigate the prognostic value of MMN for subsequent awakening in deeply sedated critically ill patients.

Early impairment of intracranial conduction time predicts mortality in deeply sedated critically ill patients: a prospective observational pilot study.

Background: Somatosensory (SSEP) and brainstem auditory (BAEP) evoked potentials are neurophysiological tools which, respectively, explore the intracranial conduction time (ICCT) and the intrapontine conduction time (IPCT). The prognostic values of prolonged cerebral conduction times in deeply sedated patients have never been assessed. Sedated patients are at risk of developing new neurological complications, undetected.

Brainstem response patterns in deeply-sedated critically-ill patients predict 28-day mortality.

Background And Purpose: Deep sedation is associated with acute brain dysfunction and increased mortality. We had previously shown that early-assessed brainstem reflexes may predict outcome in deeply sedated patients. The primary objective was to determine whether patterns of brainstem reflexes might predict mortality in deeply sedated patients.

[Starvation ketosis in a breastfeeding woman].

Introduction: Bovine ketosis is a rare cause of metabolic acidosis. It is a starvation ketosis that appears in lactating woman.

Case Report: A 29-year-old woman had a previous gastric surgery one month ago while breastfeeding her 6-month child.
