mydriasis/hypoxia

OBJECTIVE To present a case of iatrogenic, unilateral pupillary dilatation after general anesthesia for nasal surgery. Unilateral pupillary dilatation after general anesthesia has sinister implications, which might prompt further investigations. However, in patients undergoing nasal surgery, it

Two cases of fatal lightning injury are described. Fixed dilated pupils should not be taken as an indicator of death after a lightning strike. Persons who fail to breath spontaneously within one minute of lightning shock should receive external cardiac massage and mouth-to-mouth resuscitation.

Three patients were bitten by the Malayan krait (Bungarus candidus). The patients developed ptosis and generalized muscle weakness which later progressed to respiratory paralysis. All patients showed evidence of decreased parasympathetic activity manifested by mydriasis, hypertension and

The pupillary diameter and the pupilloconstrictor light reflex are the two parameters that have been studied extensively in relation to prognosis. Accurate measurement of pupil diameter or the constrictor response or the duration of the response has not been performed in studies on traumatic

OBJECTIVE To evaluate the effectiveness of prehospital medical care in head-injured patients. METHODS All head-injured patients admitted in Bicêtre hospital from 1995 to 1999 were retrospectively studied. Glasgow Coma Scale (GCS) score, mean arterial pressure (MAP) and SpO(2) measured on the field

OBJECTIVE To describe the factors associated to mortality of patients with severe traumatic brain injury (TBI). METHODS A retrospective observational study was made of patients with severe TBI covering the period between 1 January 2007 and 31 December 2010. METHODS Virgen de la Vega Hospital,

The authors have analyzed the clinical course and intracranial pressure (ICP) changes in 55 severely head-injured patients presenting with bulk enlargement of one cerebral hemisphere within a few hours after trauma. These patients represent 10.5% of a series of 520 patients with severe head injury

The protective efficacy of pentoxiphylline, piracetam, and dihydroergotoxine against abrupt hypoxia was tested in a model of acute reversible respiratory failure, where repeated apnoeic attacks were induced by inhalation in repeated hypoxic exposures was reduced in control as well as in

Neurologic injury is a significant source of morbidity and mortality in pediatric patients. In order to clarify the factors influencing outcome in pediatric patients with severe head injury, we studied 200 consecutive patients with Glasgow Coma Scale (GCS) scores of 8 or less. The following data

OBJECTIVE To identify the predictors determined early after admission and associated with unfavorable outcome or early (within 48 h) death after severe head injury. METHODS Prospective cohort study. METHODS A neurosurgical intensive care unit in a university hospital. METHODS 198 consecutive

In this article, we describe a case of a subarachnoid hemorrhage (SAH) in an acute severe asthma patient following mechanical hypoventilation. A 49-year-old man was admitted to an Intensive Care Unit with an acute exacerbation of asthma. After 3 days of mechanical ventilation (hypercapnia and

A total of 472 consecutive patients with severe head injuries (Glasgow Coma Scale score 8 or below) were studied for assessment of various risk factors affecting the outcome. The patients were divided into two groups - 299 (63 percent) patients who died and 173 (37 percent) patients who survived.

OBJECTIVE Case study reports for the first time about development of massive iris neovascular complication in course of retinopathy of prematurity related to systemic and ocular ischemic syndrome due to tracheostomy-requiring extremely severe premature respiratory failure. METHODS Premature female,

Cyanide causes intracellular hypoxia by reversibly binding to mitochondrial cytochrome oxidase a(3). Signs and symptoms of cyanide poisoning usually occur less than 1 minute after inhalation and within a few minutes after ingestion. Early manifestations include anxiety, headache, giddiness,

A boxing match with fatal outcome is described. The boxer received 21 punches in the nape of his neck, as well as many other blows. After a knock out in the 15th round he conceded the fight; some minutes later he suddenly collapsed. Deep unconsciousness, maximal dilated pupils and extensor-spasms
