Successful resuscitation from sea water drowning.

A case of a 24-year-old male who survived a near drowning despite suboptimal pre-hospital management is reported. The case illustrates the value of continuing resuscitative efforts even in the apparently dead drowning victim. (+info)
Effective interventions for nearly drowned children.

Near-drowning, one of the great tragedies in emergency pediatrics, is largely preventable. It generates particular concern and frustration among those who must treat its victims and their families. Should every drowned child be resuscitated? What treatment will minimize the risk of secondary brain injury? (+info)
Severe hypercalcemia and polyuria in a near-drowning victim.
(43/47)
A 73-year-old man was admitted because of near-drowning in a hot springs bath. Transient severe hypercalcemia and polyuria were seen during the first hospital day. It seemed that the hypercalcemia was due to acute intoxication from calcium contained in the water of the spring absorbed mainly through the alveoli. To our knowledge, this is the first case of acute hypercalcemia complicating a near-drowning in a hot spring. Analysis of serum and urine electrolytes during the polyuric phase revealed saline diuresis, which was probably due to interference by the hypercalcemia of the reabsorption of sodium and free water.

Hypoxic encephalopathy after near-drowning studied by quantitative 1H-magnetic resonance spectroscopy.
(44/47)
Early prediction of outcome after global hypoxia of the brain requires accurate determination of the nature and extent of neurological injury and is cardinal for patient management. Cerebral metabolites of gray and white matter were determined sequentially after near-drowning using quantitative 1H nuclear magnetic resonance spectroscopy (MRS) in 16 children. Significant metabolite abnormalities were demonstrated in all patients compared with their age-matched normal controls. Severity of brain damage was quantified from metabolite concentrations and ratios. Loss of N-acetylaspartate, a putative neuronal marker, from gray matter preceded that observed in white matter and was more severe. Total creatine decreased, while lactate and glutamine/glutamate concentrations increased. Changes progressed with time after injury. A spectroscopic prognosis index distinguished between good outcome (n = 5) and poor outcome (n = 11) with one false negative (bad outcome after borderline MRS result) and no false positive results (100% specificity). The distinction was made with 90% sensitivity early (after 48 h) and became 100% later (by days 3 and 4). This compared with 50-75% specificity and 70-100% sensitivity based upon single clinical criteria. MRS performed sequentially in occipital gray matter provides useful objective information which can significantly enhance the ability to establish prognosis after near-drowning. (+info)
Swimming pool drownings and near-drownings among California preschoolers.
(45/47)
OBJECTIVE: To describe a significant but poorly understood public health problem, the authors compiled data on swimming pool drownings and near-drownings requiring hospitalization for California children ages 1 to 4. METHODS: Data from death certificates were used to analyze swimming pool drownings, and hospital discharge data were used to analyze near-drownings. RESULTS: Among California preschoolers in 1993, pool immersion incidents were the leading cause of injury death and the eighth leading cause of injuries leading to hospitalization. Rates per 100,000 population were 3.2 for fatalities and 11.2 for nonfatal incidents, with a fatality-to-case ratio of 1:3.5. Total charges for initial hospital stays (excluding physicians' fees) were $5.2 million for 1227 hospital days. CONCLUSIONS: Swimming pools remain a serious hazard for young children. Primary prevention continues to be an important public health goal. Public health officials should support the adoption of laws designed to protect children from drowning and near-drownings. (+info)
Pneumonia associated with near-drowning.
(46/47)
Drowning and near-drowning can abruptly devastate the lives of both the affected victims and their families. In addition to the complications directly caused by the submersion, several indirect causes of morbidity exist. Infection is one of the complications associated with near-drowning, and pneumonia is the most severe of these infectious complications. The risk factors, microbiological causes, diagnostic approach, and appropriate therapy for pneumonia associated with near-drowning are not well described in the literature. Herein, we review the epidemiology and pathophysiology associated with near-drowning, discuss the potential mechanisms of infection, and describe the likely risk factors for pneumonia related to near-drowning. We also detail the microbiological causes of this entity and provide important clinical and epidemiological information associated with specific pathogens. Finally, we summarize an appropriate diagnostic and therapeutic approach to pneumonia associated with near-drowning. (+info)
MR of hypoxic encephalopathy in children after near drowning: correlation with quantitative proton MR spectroscopy and clinical outcome.
(47/47)
BACKGROUND AND PURPOSE: Quantitative MR spectroscopy has a proved role in the investigation of hypoxia caused by near drowning. To date, no studies have addressed the MR imaging changes that may also accompany this condition. The purpose of this study was to describe the MR imaging findings in children with hypoxic encephalopathy caused by near drowning and to compare these findings with the results of qualitative and quantitative proton MR spectroscopy and clinical outcome. METHODS: Twenty-two children (6 months to 11 years old) admitted to the pediatric intensive care unit after near drowning incidents underwent cerebral MR imaging and quantitative proton MR spectroscopy. Clinical and imaging studies were reviewed retrospectively, and subjects were grouped according to outcome: good result, persistent vegetative state, and death. Images were scored for edema, basal ganglia changes, and cortical changes, and were compared with MR spectra and outcome at days 1 to 2, 3 to 4, and 5 or more. RESULTS: Six patients had a good outcome, four remained in a persistent vegetative state, and 12 died. Generalized/occipital edema correlated with poor outcome. Indistinct lentiform nuclei margins on T1-weighted images were a frequent finding (78%). Basal ganglia T2 hyperintensity correlated with poor outcome, progressing from a patchy/peripheral distribution to diffuse high intensity. Patchy high T2 signal in the cortex or subcortical lines were specific but insensitive for poor outcome, as were brain stem infarcts. CONCLUSION: MR images in children with hypoxic encephalopathy after near drowning show a spectrum of changes. The most sensitive prognostic result may be achieved by combining MR imaging with qualitative and quantitative MR spectroscopic data. (+info)
