Are opioid overdose victims getting the rescue breathing they need?

'People might have the false impression that just giving someone a shot of naloxone and standing by is enough,' says emergency physician Adam Lund.

Along with naloxone, artificial respiration needed to restore oxygen to body, but barriers persist

With 622 deaths from illicit drug use in B.C.so far this year, paramedics, doctors and nursesare all too familiar with being called in to try and save people who are unconscious, not breathing or worse after ingesting fentanyl.

And while take home naloxone kits the opioid overdose antidote havelikely saved hundreds of people, perhaps still more could be saved, or face better outcomes, if they also were getting more oxygen into their systems through rescue breathing.

"People might have the false impression that just giving someone a shot of naloxone and standing by is enough," said Dr. Adam Lund, an emergency physician atRoyal Columbia Hospital and a clinical associate professor at the University of British Columbia.

"And so I would agree with those that express some concern that it's equally important, and possibly more important, that we increase the awareness that assisting people with their ventilation or CPR is going to be an important thing to do."

Cascade of problems

When a person overdoses on fentanyl, a "cascade of problems" begins, according to Lund. There is a decreasing level of consciousness, followed by a decreasing depth and rate of breathing, which leads to hypoxia or low oxygen in the body.

"And that begins a cascade of cellular injury to your body," said Lund, which can ultimately lead to cardiac arrest.

Cardiopulmonary resuscitation, known as CPR, is primarily designedto deal with heart attacks, when the heart suddenly stops working.

Opioid overdoses are different: it takes a comparatively long time for the heart to stop beating as breathing gradually slows.

"If you can get the air moving in and out of the chest and if you can increase the oxygen delivery, you're bringing an essential part of the recoveryof that person," said Lund.

While naloxone has received plenty of attention available almost everywhere nowthe importance of getting oxygen back into people has paled in comparison, not least because it involvesblowing into the mouth of a victim often a stranger.

Mouth-to-mouth on a stranger

"A lot of people would tell you, 'Well if I have to do mouth-to-mouth, I'm not even going to start,'" saidDr. Christian Vaillancourt, anemergency physician at the Ottawa Hospital, who also participates in the review, every five years, of resuscitation guidelines.

Through his research and study, he foundpeople are much more willing to do chest compressions, particularly on a complete stranger, than mouth-to-mouth.

"This is a real barrier," he said.

'Artificial respiration and naxolone go together when responding to an overdose,' says Vancouver Coastal Health's Dr. Mark Lysyshyn. (BC Centre For Excellence in HIV/AIDS)

Lund goes so far as to admit that the process for many, including health professionals, can be "yucky," but he realizes its importance in overdose recovery.

Dr. Mark Lysyshyn, aVancouver Coastal Health medical officer, agrees.

"We definitely want people to give rescue breaths first, because if somebody's been in an oxygen deficit, you know, their brain is dying, and so we want them to get some air in," he said.

Lysyshyn saidnaloxone and ventilation are the most important interventions to be used in a suspected overdose, that's why all the take-home naloxone kits include a face shield for mouth-to-mouthbreathing.

Still both he and Vaillancourt admitthere is nohard science showing that this type of ventilation issaving lives during opioid overdoses.

"And unfortunately we just don't have good information about whether people are giving rescue breaths," he said.

"We do have good information, though, that the take-home naloxone program is reversing overdoses and that people are surviving them ... and rescue breaths,we hope, are part of them."

Chest compressions can bean alternative

Call-takers for 911 are trained to give instruction to people trying to help someone who has overdosed on opiods, and thatincludes mouth-to-mouth breathing. But there is another option.

"Nobody will ever be coerced into it or bullied into it because there are people who just are simply not comfortable doing that," saidDr. William Dick who speaks for B.C Emergency Health Services.

In that case, instructions are given to perform CPR chest compressions.

"Because that act of of pushing on the chest and doing CPR actually moves enough air in and out of the lungs to get some oxygen in there," said Dick.

It's something Vallaincourtagrees with, that at least doing chest compressions, will provide some benefit and certainly no harm to someone in crisis.

"Even if you've never, ever been trained in CPR, you should try something," he said "It's easy:there's a chest, put your hands in the middle, push hard, push fast."
