Yep I get why CPAP won't work with a pt who's respiratory drive is absent. I can see where CPAP could be a challenge with this particular pt. (Of course I could see where bagging this particular pt could have been a treat as well).
The problem with bagging this particular patient is that BVM use without any cricothyroid pressure is likely to cause gastric insufflation and he's going to vomit again... So, use the BVM while preparing to intubate, and leave him under. Most OD patients would probably do just fine with some BVM while you wait for the naloxone to work... This guy... probably better to just intubate, scoop and run.
I'm just trying to get more up to speed on CPAP as it was added to our scope while I was on hiatus. I've seen/heard of protocols where CPAP is contraindicated in asthma's and COPD's. (Seen some where it isn't as well for that matter).
The with the CPAP on those patients is that you just have to be aware of the patient's ventilatory status. COPD patients do a little "autoPEEP" on their own.
What I'm curious about was the original comment that for drug overdoses across the board CPAP wasn't authorized. Maybe it's not that CPAP wouldn't work, but rather than their medical director only specifically authorizes CPAP for a few conditions and those conditions alone.
For a Drug OD, CPAP normally isn't indicated. Normally, reverse the OD and you restore the patient's own respiratory drive. Remember, CPAP provides airway pressure, not rate or depth of breathing. With this patient, use of CPAP MIGHT have been useful if just enough narcan was used to increase his breathing rate without waking him up. However, CPAP use might also lead to the guy expelling more gastric contents into a mask that's attached to his head with straps.
Thanks for the response.
For the OP, I can agree with the comments that waking the pt up isn't always the only option, but I also feel for how challenging the call can be. I remember a pt almost 20 years ago that was similar, younger male (20-25 yo), OD'ed with aspiration, compromised airway, our guy was jaw clenched. The charge medic 'forced' a supraglottic airway, (a PTL probably, I don't remember now), got bit in the process, then an attempt was made to wake the pt, who's LOC improved briefly and partially as his OD turned to be out both narcotic and non narcotic. He thrashed like crazy, jerked out the airway, vomitted profusely, struck the charge paramedic and crumped all over again. I believe he expired (the pt, not the charge medic
) some months later after being discharged to a rehab unit.
You've experienced one VERY good reason to leave this patient down or at least a very good indication for carefully titrated use of narcan.
In retrospect none of the choices on our scenario were well organized, but sometimes you are right on the wire and you make the choices that you make.
