I'm wondering about the risks of local anesthesia (specifically genitofemoral and ilioinguinal nerve blocks) for a bilateral inguinal hernia repair? I'm getting ready for a procedure soon (outside of the US) where they're trying to convince me that this type of anesthesia is the lowest risk option for the patient, but I'm not totally sold that the dangers are negligible. What's the actual risk of permanent nerve damage (chronic pain) with this kind of thing, and are there any other possible complications with lasting effects?
Thanks in advance. 🙂
Look, in anesthesia, there’s no such thing as "negligible" risk! Things always seem to happen right when you least expect them.
The main risks associated with those specific blocks would be:
1) An allergic reaction to the local anesthetic (have you ever had local stuff before? If yes, no biggie—if not, you'll find out),
2) Accidentally injecting the anesthetic into a blood vessel (since they use a fair amount of it, you could have serious reactions like heart arrhythmias, loss of consciousness, dizziness, tingling in your hands, or even seizures depending on the drug used. Most of these can be managed or calmed down with medication, but they are incredibly unpleasant for the patient, especially since you still have to endure the surgery itself),
3) Accidental nerve injury from the needle (this can leave some lasting issues like paresthesia or numbness—basically weird tingling or losing sensation in the area covered by that nerve. This is usually avoided by performing the block under ultrasound guidance and using a nerve stimulator, though it also depends somewhat on your unique anatomy and, honestly, how skilled and experienced your anesthesiologist is),
4) A partial or failed block (meaning the surgery goes ahead, everything looks fine, and then suddenly it starts hurting because the block didn't take or only worked partially. You've got two options there: either go full general anesthesia and get to experience all the "joys" of being knocked out, which isn't exactly fun, or the surgeons just add more anesthetic as needed while you're still awake and praying it won't hurt—which, spoiler alert, usually means it will, making things even less pleasant),
5) The chance of infection during the injection, which is super rare and usually only happens if someone is being sloppy or using non-sterile techniques.
And since it sounds like you have to deal with bilateral hernias, all of this basically doubles because they have to perform the block on both sides.
Sorry, that was a bit heavy on the worry side. :-(
Let me lighten the mood a little. :-)
Peripheral blocks might actually be the best choice for a patient because they only numb the specific part of the body being operated on, and the numbing lasts for a good while after the surgery.
You aren't pumping drugs into your system that beat up your liver, lungs, brain, or kidneys (which is what happens with general anesthesia). You don't wake up feeling like a zombie, either. Plus, you don't deal with that post-op nausea and vomiting, which hernia surgeries can sometimes trigger. When people wake up from general anesthesia, they often tense up or try to cough against the breathing tube; they strain their abs, which can actually jeopardize the surgery if the stitches pop. It doesn't happen constantly, but it's a real thing, and it means the hernia could come back and you'd be heading back into surgery.
You could also go the route of regional anesthesia like a spinal or epidural block, which would essentially numb your legs and lower abdomen for a few hours. If it's a spinal, they usually tell you not to get up for 24 hours. With an epidural, you wouldn't necessarily need to stay bedridden for a whole day unless they accidentally hit the spinal space. You'd use a smaller amount of anesthetic compared to the blocks mentioned above, and they could handle both sides. I think the potential complications for those are listed somewhere else on this forum.
I think I’ve covered just about everything you asked me:
But honestly, the big thing is this—during your pre-op screening and when you actually sit down with the anesthesiologist right before the surgery, just lay it all out there. Talk through every single fear, every "what if," and even your hopes. Make them explain exactly why they believe a specific type of anesthesia is the best call for your body.
At the end of the day, it really boils down to how much experience the anesthesiology team has and how often they perform that specific technique. If you're at a major medical center where they do this kind of procedure routinely—especially if they're using ultrasound guidance—you can probably feel pretty confident following their lead.
Since we're talking about a bilateral hernia, though, don't be afraid to ask their opinion on spinal or epidural options too.
Anyway, that’s my two cents. Phew.
Best of luck with the anesthesia and the whole surgery!
