Four
days of planned relaxation on ‘Our
Dreamtime’ over the Easter break presented us with an unexpected test of
our preparedness to handle a medical emergency when Karen suffered a very
painful and potentially dangerous strike from the poisoned barb of a stingray.

It
all started well enough with a very enjoyable Sunday afternoon, downwind sail in
15-18 knots across thirteen and a half nautical miles of Moreton Bay from our
marina berth in Manly Boat Harbour to Horseshoe Bay on Peel Island. Karen
helmed most of the near three hour journey getting more acquainted with the how
the Whitby 42 ketch behaves on a broad reach with modest following seas.

We
were fully aware that the combination of the Easter weekend and perfect weather
would make this beach lined safe haven a Mecca for boats of all sizes but two
years cruising in the Mediterranean visiting many overcrowded anchorages has
taught us not to avoid a beautiful spot just because others might be there.
Besides, most of the boats would be gone the next day as the majority of the
population prepared to head back to work. We, on the other hand, would be
staying on until Wednesday or Thursday in comparative solitude.

Although the bay was very well populated when
we arrived mid afternoon, we had no trouble finding a good spot to anchor in
just five metres of water. We soon had the boat secured, sunscreen applied,
deck chairs out with snacks and cocktails in hand. We had full, four day agenda
of doing very little firmly laid out and were determined not to deviate from
the plan.
 |
| A relaxing afternoon on the stern |
That
evening, mother nature provided the entertainment double feature of a stunning
sunset over the mainland with just a very brief intermission before the equally
impressive sight of a near full moon appearing large and orange over the sand
peaks of Stradbroke Island to the east. Tender steaks off the BBQ accompanied
by a couple of fine reds enjoyed on the stern of our Whitby 2 ketch put the
punctuation mark on a great day on the water.

Next
day dawned clear and calm with just a mild breeze blowing off the beach. After
a relaxed morning aboard, we had a light lunch before lowering the dinghy off
the davits. We then went for a ride through the bay checking out the huge range
of boats at anchor before going ashore on the beach.
The
warm, clear water and sandy shallows of Horseshoe Bay are particularly inviting
and we had a lovely swim. With the tide running out, we began wading along in
waist deep water parallel to the beach enjoying the sunshine, alternatively
towing and pushing our dinghy along between us.
Suddenly Karen fell to the side
and said she’d stood on something and been stung. We spotted a small stingray
scurrying away across the bottom which we assumed to be the culprit. On
examining Karen’s leg we found a small puncture wound bleeding on her ankle
which she said was quite painful with a burning sensation akin to being poked
with a soldering iron.
We
made our way into shallower water so it was easier for Karen to get up into the
dinghy but it was still very difficult for her to even manage this given the pain she was experiencing. Weheaded straight back to our boat. In the short time it took, Karen’s
foot had begun to swell and the burning sensation was increasing and spreading up her leg. The normally
simple climb from our drop down swim platform up to the stern proved a very
painful challenge which she conquered with gritted teeth.
Once
in the cockpit we washed the injured area with fresh water and administered two
paracetamol painkillers and an antihistamine in case of allergic reaction. Then
I went straight for our 450 page first aid manual only to find a totally
inadequate, very brief three line section on the treatment of stingray
stings. Thank goodness for modern
technology. We were well within service range for our mobile phones and 3G wifi
so the next step was to ask that know it all Mr Google. A search of ‘Stingray Sting Treatment’ revealed a long list of sites with
detailed, multi-step guides to the appropriate first aid and subsequent
treatment. Rob quickly read through the
first and then scanned another three to make sure they all basically agreed
with each other. (Just because it’s on the internet doesn’t mean it’s always
true. Look for more than one source)
Any
barb strike to the torso must be treated as an extreme medical emergency and
professional medical assistance should be sought immediately. However most stingray injuries occur to the
feet and all sites provided first aid information based around that premise. Here’s
a step by step summary of the advice provided and how we implemented that
advice. (Note: The same first aid treatment is also recommended for similar marine venomous stings such as stonefish.)
1
While still in the water irrigate the wound to remove fragments of spine and
tissue. A small amount of bleeding at
this stage may assist the process of washing away toxins. Remove victim from
the water.
We
examined the wound immediately and could see no pieces of the barb and were
then in the water for a minute or two moving to a shallower area before Karen
was able to climb into the dinghy. This provided time for the salt water to
wash through the wound.
2
Apply pressure above the wound if it is bleeding.
By
the time Karen was out of the water bleeding was minimal so this was not an
issue. Recommended treatment if bleeding is excessive is a pressure bandage
ABOVE the wound.
3
Flush the wound in fresh water then soak in water as hot as the person can
tolerate (approximately 43C - 110 F). As toxins may cause numbness of the
effected limb, check the temperature with a non effected hand/foot to ensure
it’s not so hot as to cause burns. When any bleeding has stopped use tweezers
to gently remove any obvious pieces of spine.
Prior
to reading this we had automatically flushed Karen’s wound with fresh water as
a matter of course as soon as we reached the boat. However, I had also given
Karen a bottle of cold water to take the antihistamine and painkillers which
she had then momentarily used to put against the wound like an ice pack. This
caused a seriously elevated level of pain so NEVER use an ice pack on this type
of injury. Fortunately we had run our engine to charge batteries that morning
and had a plentiful supply of very hot
water literally on tap. Karen was sceptical about plunging her burning foot
into near scalding water but once accomplished she gained an immediate level of
pain relief. The hot water is also said to deactivate remaining toxins to a
degree. We found no obvious pieces of spine to remove.
4
Wash wound with soap and water. Apply tropical antibiotic ointment. Apply
breathable, gauze dressing. Do not cover the wound with tape or close it with
stitches.
By
now any touching of the wound sent the pain meter to the maximum so this is
something we didn’t do. The wound look very clean and Karen preferred to keep
it down in the hot water for the pain relief it provided. The level of pain
ebbed and flowed coming in waves reaching up as far as the thigh which was
consistent with what was described on the internet. The websites all said that oral
antibiotics are usually prescribed to limit infection and need to be
continued for at least 5 days after any
signs of infection have cleared. Ever since we cruised in South East Asia we
have carried a very extensive medical kit on board including just such a broad
spectrum antibiotic so we administered one of those immediately to get ahead of
any nasty bugs the aggrieved stingray may have left in Karen’s leg.
5 Go
to hospital emergency department.
This
is the stage when nurse and patient started to have divergent views. Karen did
not want to go, saying we’d done all the treatment so everything would be fine
soon. She’d been looking forward to four days of doing not much and no little
stingray was going to spoil it. I on the other hand had just read about the,
admittedly rare but still possible, negative outcomes which escalate through necrotising
infections where the surrounding flesh
dies and can result in amputation in extreme cases up through allergic reactions
to the toxins. The symptoms of which include •Difficulty breathing •Tightness
in throat • Itching • Nausea •Fast pulse • Dizziness •Loss of consciousness
The
line that read “Perform cardiopulmonary resuscitation (CPR) if necessary” was
enough to have me ready to weigh anchor on spot. It was time to call in reinforcements to win
this little impasse.
The Queensland Government Health provides an excellent telephone help
line, 13 HEALTH (13 43 25 84) designed to lessen the load on hospital emergency
departments by providing qualified staff to advise to people with medical
issues on who to talk to and how quickly you should do it. Depending on the
issue, many people are referred to more appropriate treatment providers other
than hospital casualty departments. You can phone 24 hours a day 7 days a week
for the cost of a local call.
I placed a call to them and was quickly connected to a registered nurse who immediately wanted to speak to Karen. She sought and was given a complete rundown on what happened, what treatment we’d administered on board and Karen’s basic medical history. The result was more a directive than advice. “Continue the hot water treatment and get into the harbour as quickly as possible. You will be going to the nearest emergency department which is at Redlands Hospital. Call me back when you are thirty minutes from the dock.”
Listening from the sidelines I knew the battle was won long before Karen was off the phone, by which time I had the dinghy up on the davits, swim platform stowed and was securing everything below. Karen mounted one last rear guard action with an unconvincing “I’m not sure about this.” When I asked if things were the other way around and it was me who’d been stung would she want to go or stay she meekly ran up the white flag with a quiet, “Go.”

Engine on, anchor up and away we went. In contrast to our meandering three hour, 13.5 mile sail to the island, our course back was a series of straight lines cutting close to each mark which abbreviated the distance to 12 miles while the engine turning at 2,000 rpm delivered 6.5 to 7 knots. Regular changes of bucket saw the hot water treatment continue enroute. A flurry of phone calls began as we approached the channel into Manly Harbour less than ninety minutes after getting underway. Karen’s pain levels were still elevated and she was now quite nauseous. The 13 HEALTH advisor confirmed the need for hospitalisation and an ambulance was arranged to meet us at the dock. A call ahead had great marina neighbours standing by to meet the paramedics at the gates and guide them to the boat while others were ready to take lines to help Rob dock the boat solo.

Within minutes Karen was examined on board
which revealed elevated blood pressure. The paramedics asked for a complete
rundown of the treatment we’d done and we also had a list ready for them of
exact medication and dosages administered. We were relieved when they confirmed
all were correct. Karen couldn’t help playing things down suggesting it was a
lot of fuss over just a very small stingray. However, when it came time to leave
the boat, the normally simple task of getting out of the cockpit and onto the
dock revealed the truth. Her severely swollen foot could bear no weight at all
and simply moving it shot waves of pain through her entire leg. It was another
case of grit the teeth and punch through the pain barrier half crawling, half
hopping before collapsing on the gurney on the pontoon light headed and
struggling to keep the increasing nausea at bay.

Once in the ambulance an ECG was done
which showed some irregularities. With the marvels of modern technology again
in play this was forwarded to the ER at the hospital in advance of
transportation. They waited in the car park until a second ECG showed things
were stable before hitting the road.

On arrival at the hospital the staff
reviewed the paramedic file notes, treatment we’d administered and again gave
the nod of approval to our actions. Karen’s vitals were taken again and the
puncture wound examined. It was now over four hours since the sting so the
likelihood of allergic reaction was reducing by the minute. The nausea had
passed, blood pressure settled back to near normal and the pain was slowly
receding. The only real concern was whether any fragments of the barb remained
in the wound which was much too painful to withstand anything in the way of
prodding and poking. An x-ray showed no signs of anything but the radiologist
suggested only an ultrasound scan would show up tiny fragments but that was not
possible due to the painful swelling. Karen was also told that she was only the
second stingray victim they had treated at the hospital.
 |
| Hard to believe that small puncture wound on the ankle could cause so much pain and swelling. |
After monitoring for a couple of hours, Karen
was discharged with course of antibiotics, the very one we’d administered shortly
after the sting, and the instruction to come straight back in for an ultrasound
if signs of any infection appeared at all.
Now a doctor saying you can go home is one
thing but actually getting there is another. She’d arrived in an ambulance with
two very qualified attendants. Now there was just us and our old Ford Explorer.
Despite the improvement in her foot, Karen could barely manage the assisted
hobble three metres from the emergency department door to our car. We live on
our boat in the marina and although we are on the closest pontoon to the car
park it’s still a distance of 100 metres or so including down a ramp the
steepness of which depends on the tide.
Despite trying to put as much weight as
possible on me, Karen only made it a few metres before coming to complete stop
in far too much pain to continue on. If nothing else we sailors are a
resourceful lot and before she knew it I was lowering her backside into one of
the marina’s trolleys and wheeling her down the pontoon like a bag of
groceries. And so ended Our Dreamtime’s first and hopefully
final medical emergency.
1 We both love stingrays and know they are
timid, non-aggressive creatures of greater intelligence than most marine
creatures. We also know that in their sandy shallows environment we should both be on the lookout for them and shuffle
our feet through the sand as a warning of our approach rather than bouncing
along in big steps. On this occasion, Karen was unsighted walking at the back
of the dinghy and we were both negligent in the way we were moving through the
water.
2 While ensuring we had what appeared to
be a comprehensive first aid manual on board we had never looked to see if it
had adequate information regarding treatment of marine incidents we may
experience. In fact we’d hardly examined it at all. It clearly didn’t provide
the information we needed and if the sting had happened away from internet and
phone access we would not have been able to respond anywhere near as well.
3 We did not head back to port and within easier
reach of medical support immediately following our initial first aid treatment.
Procrastination could have serious, even fatal consequences should a person
have a more adverse reaction to the toxin. Neither the size of the stingray or
the puncture wound is relevant.
2 We did only very basic first aid until
being sure of the appropriate further treatment steps to take. The first rule
of medicine is ‘Do no harm’.
3 We had adequate first aid supplies and
medications on board. Thanks to the assistance of our understanding GP we carry
a range of medication which, in his words, are to “to stop you puking, make you
poo, stop you pooing, antibiotics to beat the bugs and a range of different
pain killers if you do something stupid to yourself.” Despite having much
stronger pain relief on board Karen chose to limit herself to paracetamol
to keep her wits about her and take an active part in her own treatment.
 |
| Our medical kit is extensive and well labeled so everything can be found quickly if needed. |
4 We accessed assistance available to us
including the internet, Government help line, friends, ambulance and emergency
room. Although no actual treatment was deemed necessary in the ER, the
situation could have been very different. As it was, despite immediate,
appropriate first aid, Karen’s reaction to the toxins was enough to cause
irregular heart beat shown on the ECG and elevated blood pressure quite apart
from the pain inflicted. The peace of mind her time in the ER provided me is incalculable.
Stingrays
 |
| Unlike these small examples, stingrays are usually camouflaged in the sand. (Image from internet) |
Stingrays
are non aggressive and remarkable intelligent creatures. But if frightened
,cornered or captured they can and will react purposefully and with great
speed.
Stingrays
are not capable of voluntarily raising and lowering their stings. It is reflex
action. The wound comes from a powerful arching forward flick of the tale.
During a sting the tip of the spine and the barbs pierce and lacerate the skin
of the victim. Venom then simultaneously passes into the wound.
 |
Stingray spines have many multiple barbs along both edges which often break off inside a puncture wound.
(Image from internet) |
Stingrays
are known to frequently sting persons who capture them and then unwisely
attempt to bring them into a boat, as well as when they are accidentally trod
on by a person wading in the shallows. It is also dangerous to swim directly
over a stingray as the spine may pierce the person's trunk with possible fatal
consequences.
As
of 1996, only 17 recorded deaths had
occurred worldwide from stingray barb injuries. The first reported Australian
death in 1969 was contributed to a stingray barb directly to the heart of the
patient, although there was no witness to the event. In 1989 a delayed fatality
in a 12 year young boy stung after a freak accident in a small boat was
reported. The sting of an air-borne stingray caused direct penetration of the
left lung and the heart of the young victim.
The
most famous victim was Steve Irwin who died in 2006 after being pierced in the
chest by a stingray barb while filming an underwater documentary in Far North
Queensland.
Avoidance
of the most common injury (which is a sting from a stationary stingray to the
lower leg in the shallows) can be avoided by inspecting the bottom of the area
(eg boat ramp, shallow water, etc) and shuffling when wading in shallows. If a stingray is seen while snorkelling or
diving, leave it alone! If a
stingray is caught from a boat, cut the line or release the net and allow it to
escape. Never pull it on board.
The
stingray's intelligence far exceeds that of turtles and sharks. However their
handling should not be attempted (except under expert supervision).
POSTSCRIPT:
14 April 2015
Seven days after suffering the sting Karen is still suffering a burning sensation and discomfort in her foot but is at last now able to spend more than just very brief periods on her feet. The lingering power of the toxin injected by a single strike from a relatively small stingray is incredible but fortunately she is well on the way to a full recovery.
