In a well established beach lifesaving service, respiratory or cardiopulmonary arrests occur in only 0.5% of all rescues and in 10% from those who need medical attention (1). Although there are some controversial issues, it is well established on these cases the need for respiratory support alone or cardiopulmonary resuscitation, assistance of a medical doctor at the accident site, and hospitalization.
But one of the most difficult and challenging lifeguard decisions for those who provide Basic Life Support Ã¢â‚¬â€œ BLS or Advanced Life Support Ã¢â‚¬â€œ ALS at the rescue site is how to recognize the severity of the drowning victims with less life-threatening conditions appropriately and consequently be confident in front of the critical public to do the right intervention. Our purpose is to reassure lifeguards confidence in front of the public, establishing simple recognition signs to let them know the drowning severity, treatment and outcome.
Methods: We reviewed literature (Medline, references from previous articles, review articles and books and ILS Policies) searching for the words drowning and severity. All data which does not focus on rescue site were excluded. We focused our search to answer 3 questions: How to recognize drowning severity? How to treat according to severity? And when a lifeguard should seek medical advice or support?
Results: Two large researches were reviewed with a total of 87,339 rescues (1,2). From those, 3,234(3.7%) cases needed medical attention at the rescue site, but severity evaluation was based on 2,678 cases. Medical attendance was available in 100% of cases and was responsible for treatment and for triage to release home or for hospitalization. Drowning severity, treatment decision, outcome/mortality and the need to seek for medical advice or support is summarized in table 1.
Discussion: One of the most difficult and challenging tasks a lifeguard must face is the giving of first aid. This part of his or her responsibilities requires lengthy theory and practical training exercises using many different situations. This is always done by the lifeguard, alone or with a partner, in front of the public who often interrupt with conflicting comments. In this paper we summarized in one table all the important information on drowning first aid to remind lifeguards, while on duty, what to do after the rescue of the victim. This was based on large rescue reports (1,2) and contributes to guide and develop standardized treatment protocols and also in comparing outcomes with different levels of severity of injury, thereby allowing lifeguards and medical staff to speak the same language - one team, one goal.
|Learning Outcomes|| |
Table 1. Evaluation of 2,678 drowning severity and treatment decision scheme at the rescue site (Based on the assistance of 87,339 rescues) (1,2) and the indications needs of further medical help after rescue (3).
0 to 6.4
Conscious, normal auscultation, no coughing, foam or difficulty in breathing
Evaluation and release from the accident site without further medical care if no other disease associated.
56 to 65
Normal pulmonary auscultation, coughing, no foam in mouth or nose
Rest, warm and calm the victim. No further medical care.
19 to 20
Rales in some pulmonary fields, small amount of foam in mouth or nose
5 liter oxygen per minute by nasal cannula; warm and calm the victim; recovery position, hospitalization
0,6 to 1,2
3 to 3.3
Acute pulmonary edema with large amount of foam in mouth or nose, normotension, palpable radial pulse
15 liters oxygen per minute by non-rebreathing mask, intubation when possible; recovery position if unconscious; hospitalization.
3.6 to 5,2
1.1 to 2
Acute pulmonary edema with large amount of foam in mouth or nose, hypotension verify by no radial pulse but palpable carotid pulse
Grade 3 treatment extended by crystalloid infusion via peripheral vein until restoration of Systolic Arterial Pressure > 90mmHg; hospitalization
19,4 to 22
1 to 1.5
Isolated respiratory arrest
Mouth-to-mouth (when possible with 15 liters of oxygen) until restoration of normal breathing, then treat as grade 4.
31 to 44
10 to 12
Start CPR; insert tracheal tube, obtain venous access, give epinephrine 0,1 mg each 3 minute; ecg monitor and defibrillate if necessary. After successful CPR: follow grade 4.
88 to 93
Confirm submersion time over 1 hour, or obvious rigor mortis, putrefaction or dependent lividity
Do not start BLS or ALS; arrange morgue.
Should always receive medical attention (ambulance and/or hospitalization): Grades 2 to 6 and any patient in whom a serious condition is suspected such as heart attack, spinal injury, trauma, brief lost of consciousness, asthma, epilepsy, stinger, intoxication, delirium etc.
