Secondary drowning in a patient with epilepsy

Medical Care for Swimmers

Swimming is one of the most popular sports worldwide. Competitive swimming is one of the most watched sports during the Olympic Games. Swimming has unique medical challenges as a result of a variety of environmental and chemical exposures. Musculoskeletal overuse injuries, overtraining, respiratory problems, and dermatologic conditions are among the most common problems swimmers encounter. Although not unique to swimming, overtraining is a serious condition which can have significant negative impact on swimmers' health and performance. This review article is an attempt to discuss various issues that a medical team should consider when caring for swimmers.

A rare type of drowning with a latent period following surviving an episode of immersion

Drowning is a leading cause of accidental death worldwide and its diagnosis is an important part of forensic investigation. It is generally acknowledged that hypoxia due to airway obstruction by fluid is the primary mechanism of death in drowning. Drowned individuals are usually found dead in the water or show severe clinical signs once out of the water. However, sudden death due to drowning after a short period of recovery following immersion/submersion has rarely been reported. A case of a 40-year-old man who died suddenly due to severe pulmonary edema about 40 min after he was recovered from an episode of immersion is reported. We suspected delayed lung injury due to water aspiration as the prime cause of death. This rare type of drowning should be well recognized by a clinician or forensic pathologist.

[Retrospective analysis of 44 childhood drowning accidents]

BACKGROUND

Worldwide, drowning is the second leading cause of unintentional death and the leading cause of cardiovascular failure for children [1-3]. The number of near-drownings, where the incident is survived for at least 24 hours, is assumed to be four times as high [5]. In the years 1994 until 2008 there were 44 cases of drowning treated at the children's department of the University of Leipzig. This number shows that even in a medical centre drowning incidents are only occasional incidents. Therefore it is important to know the sequelae and handlings to be able to react in case of an emergency.

PATIENTS

A total of 44 children suffering a drowning accident within the last 48 hours who were treated during the period of 01.01.1994 through 30.06.2008 at the Children's Centre at the University of Leipzig.

METHODS

A retrospective analysis using a structured questionnaire was done. Social demographic data, accident progress, clinical results and progress as well as outcome of the cases were investigated.

RESULTS

During the analysed period in the median three children were treated each year after drowning incidents. Clustering in the summer and winter months and on the weekends was recognizable. The median age was 3.33 years and the group of high risk were children aged 1-3 years, especially boys. Sixty percent of the children came from stable social backgrounds. Half of the children suffered from drowning in created swimming pools or ponds, the rest in natural waters, public pools and sources of water in the household. The median submersion lasted 2 minutes. Correlation of submersions below 1 minute with a good, and submersions above 10 minutes with a negative outcome was shown. A Glasgow Coma Scale (GCS) of 3 points (n = 15) and pupils without light reaction (n = 14) were associated with a lethal outcome or residual neurological deficits. Looking at the laboratory values, correlation between severe acidotic pH-values with a very low base excess, high blood sugar as well as high lactate values and a poor outcome is revealed. Six patients died within the first 24 hours, 6 more over the course suffering organ failure or brain death. Five children retained neurological damages. Twenty-seven children could be released from the clinic healthily.

CONCLUSION

The risk of suffering a drowning incident is highest for boys aged 1-3 years, playing in the yard by themselves. Prognosis is depending on multiple factors and especially the circumstances of the accident. High influence is seen in the time of submersion and the need for cardiopulmonary resuscitation. Clinics and laboratory values at the time of hospital admittance may hint to the outcome. Basic life support at the scene of the accident has the highest impact on the outcome. Training of parents and supervisors in prevention and first aid after drowning incidents can avoid accidents.

Forensic investigation of submersion deaths

CONTEXT

The diagnosis of the cause and the establishment of the manner of death in submersion cases are routine challenge for forensic pathologists as it presents considerable diagnostic difficulties.

OBJECTIVE

To concisely review the main questions during a submersion death investigation and to give the respective documented answers.

DATA SOURCES

The search strategy included a literature search of PubMed, Medline and Google Scholar databases, as well as a review of the cited references by the identified studies and a hand search of relevant textbooks and reference works.

CONCLUSIONS

A complete autopsy, histopathological examination and full toxicological screening are important to determine whether death indeed followed submersion in the water, or to see whether any natural disease or substance use have contributed or caused death. In ambiguous situations, the co-estimation of circumstantial evidence may be of invaluable importance toward the conclusion concerning the cause and the manner of death. The thorough forensic investigation of the submersion deaths not only serves the justice administration, but it also presents considerable benefits for the public health.

Subcapsular liver haematoma after cardiopulmonary resuscitation by untrained personnel

Although early cardiopulmonary resuscitation (CPR) is associated with increased survival of sudden cardiac arrest victims, it may also result in miscellaneous injuries. A 25-year-old inebriated man rescued from drowning in a swimming pool was apnoeic and pulseless after being pulled out of the water. Successful CPR was provided by untrained bystanders, including abdominal thrusts thought to remove water from the airways and chest compressions to provide haemodynamic support. As the patient progressively improved during his subsequent hospital stay, he complained of right upper abdominal and thoracic pain. A computed tomographic scan showed a 11 cm subcapsular haematoma contiguous to the right hepatic lobe. A favourable outcome was obtained after conservative, non-operative treatment. Subcapsular haematoma of the liver is a potentially life threatening complication that warrants consideration in survivors of cardiac arrest who have received closed chest compression and/or abdominal thrusts.
