Laughing Gas Making Its Way Back Into The Labor And Deliver Department

Thursday, April 21st, 2011

According to a recent article published by MSNBC, laughing gas or nitrous oxide is making its way back into labor and delivery units in American hospitals. Although laughing gas has long been used as a pain relief in various countries, including Canada and the U.K., it has lost its popularity in the U.S. Well, maybe not for much longer.

It appears that a number of hospitals are now considering making laughing gas available as a pain relief measure for women in labor. A hospital in San Francisco and another in Seattle have been using laughing gas in their labor and delivery units for a while. Hospitals like Dartmouth-Hitchcock Medical Center plan to offer laughing gas to laboring mothers in the immediate future. Dartmouth-Hitchcock’s plan is currently being reviewed by the federal government, and arrangements are presently being made for the procurement of delivery equipment for laughing gas. Vanderbilt University Medical Center may begin offering laughing gas as well later this year.

History

Laughing gas is not a new pain relief method. Its use had become very common in hospitals when Joseph Thomas Clover invented the gas-ether inhaler in 1876. Particularly, its use in the labor and delivery setting had been very common before the introduction of epidural and spinal anesthesia. Because laughing gas is unable to eliminate pain to the same degree as epidural or spinal anesthesia, it simply could not compete with the more sophisticated pain relief alternatives, which entered the marker in the 30s and 40s.

What is laughing gas?

Nitrous oxide, commonly known as laughing gas or sweet air, is a chemical compound with the formula N2O. It is an oxide of nitrogen. At room temperature, it is a colorless non-flammable gas, with a slightly sweet odor and taste. It is used in surgery and dentistry for its anesthetic and analgesic effects. It is known as “laughing gas” due to the euphoric effects of inhaling it, a property that has led to its recreational use as a dissociative anesthetic.

Laughing gas as an important pain relief alternative

Although laughing gas can only take the edge off pain, it just might be an important alternative to other more conventional pain relief methods. The patient does not have to rely on an anesthesiologist to administer the gas. The patient can herself choose how much gas to administer at any time. The effects of the gas are not long-lasting. Therefore, the patient does not have to recover in a post anesthesia care unit. Importantly, there is no associated loss of sensation and motor function during the delivery process. As such, the gas does not interfere with the woman’s ability to breath and push during labor. Laughing gas is also not known to have any adverse effects on the baby in utero.

The administration of laughing gas does not require any invasive medical procedures. By contrast, consider epidural anesthesia: An epidural requires that an epidural catheter be threaded into the epidural space, which is only about 2 mm wide. Any mistake and the consequences can be catastrophic. Epidurals have been known to cause spinal cord injury secondary t0 toxicity, spinal cord infarcts, severe hypotension, paraplegia, epidural bleeding, and even death. None of these complications are associated with the use of laughing gas.

According to Suzanne Serat, a nurse midwife at Dartmouth-Hitchcock Medical Center:

We have a number of people who don’t want to feel the pain of labor, and nitrous oxide would not be a good option for them. They really need an epidural, and that’s perfect for them. […] Then we have a number of people who are going to wait and see what happens, and when they’re in labor, decide they’d like something and then the only option for them is an epidural but they don’t need something that strong. So they would choose to use something in the middle, but we just don’t have anything in the middle.

Nitrous oxide may just prove to be that middle option for many women who prefer to give birth without the use of powerful and potentially dangerous analgesic/anesthetic agents. If you are an expectant mother, ask your obstetrician if nitrous oxide is a pain relief option that may be available to you during labor.

5 Questions to Ask Your Obstetrician Before You Go to the Hospital

Epidural Analgesia – What Should an Expectant Mother Consider? What are the risks?

Week in Review: If you missed this past week’s blogs – catch up!

Sunday, April 10th, 2011

This past week was a busy one for our bloggers. It was also a very busy week in our law practice. Over the last two months, we have also had two new lawyers join us – Sarah Keogh and Jason Penn. Sarah has contributed a number of posts already. Jason , who just started this past Monday, will soon be sharing his contributions, thoughts and comments with you as well. We’re very happy to have both of them. I’m sure you join us in wishing them a very warm welcome.

Last week our writers covered a number of topics related to health, medicine, child safety, medical technology and patient safety. We started the week off with a piece by Brian Nash on some key facts women need to be aware of when having an epidural for labor, delivery and post-partum pain relief.

Epidurals

There can be no doubt that thousands of epidurals are administered to women every day throughout this country. This form of analgesia (pain relief) has become probably the most popular form of anesthetic management and apparently is generally believed to be essentially risk free. As this week’s piece, Having an epidural when you have your baby? 3 questions to ask the doctor, reports, some literature gives the figure of complications from epidurals as high as 23% - ranging in severity from minor inconveniences, to life-long major disabilities and even death.

This particular piece was written as a result of several cases in which we have been involved when women, who had undergone an epidural, became essentially paralyzed from the waist down. We raise some questions for women to ask the doctor and suggest they just might want to ask those questions before they find themselves in the process of labor or when they are going through the recovery phase of having given birth to their baby. We believe it’s an important piece for women – and frankly for all – to read so that they have a much better idea of what they should expect with an epidural and what the risks and benefits are of this wonderful yet potentially life-altering anesthetic technique.

Shaken-Baby-Syndrome

On Wednesday, Jon Stefanuca again brought to the public’s attention a problem that is probably as old as childbirth. Everyone who has had the experience of taking care of a child – particularly a baby – knows that along with the joy of parenting comes the physical and emotional toll on parents and care-givers. The human condition makes us all susceptible to being less than completely tolerant, forgiving and gentle with little ones when we are under stress, frustrated or just plain exhausted. The response to the persistent crying can simply not be “a good shake.”

Medicine and science (and unfortunately the courtroom) have given a name to a syndrome of injury babies can suffer when that “just a good shake” approach is used. While a parent or care-giver may think it unimaginable to strike a child, they may not realize just now much harm they can do with “just a good shake.” Jon brings this information and some expert tips and tricks on how to deal with these difficult times parents and care-givers face in their everyday lives in his piece Shaken Baby Syndrome – What we all should know to prevent child abuse.

Makena: New Anti-Prematurity Drug

Thursday, Sarah Keogh reported on a relatively new drug called Makena, which has been found to help pregnant women, who have previously had a premature infant. I say “relatively” since according to Sarah’s piece, a compounding pharmacy could and was making this medication prior to the FDA giving K-V Pharmaceutical Company the exclusive rights to manufacture this drug for a period of 7 years.

Read Sarah’s piece, Makena: Drug to fight prematurity leads to major firestorm, and see what the controversy is all about. How could people possible be upset with a drug that can fight premature birth? Prematurity is one of the major causes of significant childbirth injuries such as cerebral palsy. Sarah’s blog makes it all too clear why people are upset and why the March of Dimes withdrew its sponsorship for Makena.

Medical Technology and Patient Safety

The week ended with Part II of my series on medical technology and whether all the new toys, bells and whistles of our modern healthcare system are truly advancing safe, efficient and effective delivery of healthcare. The week’s piece focuses on perhaps one of the largest advances in the healthcare industry – electronic medical records (EMR).

The blog, Medical Technology and Patient Safety – Part II – EMR’s (electronic medical records), brings a lawyer’s perspective to this topic. Much has already been written – and frankly will continue to be written – about EMR’s by the medical profession. Controversy has filed the pages of journals and at times probably slowed traffic on the internet (okay – maybe that’s a bit of an exaggeration) since this new marvelous technological advance was rolled-out in our medical institutions.  Those writing and fighting about it have been the end-users themselves – the medical professionals, who have to deal with the issues and flaws that have surfaced with this wonderful new technology. I thought it was about time to tell you how this plays out by another end-user – the lawyer who now deals with EMR’s. This piece is also intended as the foundation for what we as lawyer have seen play-out in terms of patient safety and health as a result of EMR implementation.

Sneak Peak of the Week Ahead

I anticipate that next week we’ll be seeing Jason Penn with his first blog on a recent report about numerous safety violations by hospitals in our practice jurisdictions – Maryland and Washington, D.C. Mike Sanders will be bringing to our readers aN old but back-in-the-news report on super infections, which still seem to be – unfortunately – thriving in our nation’s hospitals. We’ll start off this coming week with a piece by Theresa Neumann, our highly acclaimed in-house physician’s assistant expert, on spinal stroke. We all know about strokes that can damage the brain. Theresa will be sharing her insights on an equally devastating stroke of the spinal cord. I also suspect – shhh – that we’ll be reading more from Sarah Keogh this coming week. If the practice of law doesn’t get too much in the way, I am also hoping to share with you some real life examples – from a lawyer’s perspective – of just how EMR’s may not be advancing the causes of patient safety and health.

As with all our blogs, we sincerely invite you to not only read our thoughts and comments but to also share yours with us and our readers. Our latest stats show that around 10,000 pages are viewed by our readers and visitors every month!

Having an epidural when you deliver your baby? 3 Questions to ask the doctor!

Monday, April 4th, 2011

Be your own advocate - ask questions!

Thousands of women will have an epidural today to help them through their labor, and many of them will have a running epidural after they have their baby delivered. This is especially true in the time period for those who have had a C-Section.

There’s no doubt that epidurals have been a wonderful tool for doctors to provide patients with relief from the pains of labor and the pain and discomfort following delivery – mainly after a C-Section.

Because they have become so commonplace in hospitals throughout this country – and the world – they seem to have been taken for granted as being “safe” – not just effective. For the most part – they are safe, but they clearly have significant risks associated with them.

Some reports claim that the overall complication rate for epidurals is 23%. These complications range from very minor (e.g. some nausea, vomiting, itching, headaches) to the most major of complications – death of the mother and/or her baby. In between these two extremes lie some very devastating injuries to both a mother and her baby. Just some of those reported are damage to the mother’s spinal cord leading to motor (ability to move legs) and/or sensory (ability to feel sensations) injuries, bowel and bladder dysfunction, foot drop and a host of other potential – thankfully rare – complications.

There is a popular book that many expectant mothers have considered their bible over the years – What to Expect When You’re Expecting, which is now in it’s fourth edition, according to Amazon.com. While no doubt this has been a valuable resource for many moms-to-be, one medical author takes some exception to the section on epidurals:

Epidural anesthesia has become increasingly popular for childbirth. The popular book, What to Expect when You’re Expecting, for example, portrays epidurals as perfectly safe. The risks, however, may be greatly underplayed.

It’s been many decades (four in one instance) since I personally went through the “birthing” process as a parent-in-waiting. I must admit, I have not purchased or read the latest edition of this book so I cannot vouch that this portrayal of epidurals being “perfectly safe” is still the message of this popular book. Obviously it was at the time of the quote by this Canadian medical writer.)

What expectations do YOU have for your special day?

I suspect that many of you are like I was in envisioning what your experience will be like when the day arrives. You have your bags packed, back-up coverage in place if needed, car gassed. The moment arrives and off to the hospital you go. You register, get in your room, the fetal monitor is applied, and you pass the time remembering (or trying to remember) all those things you learned in your birthing classes. Your epidural is placed and all goes smoothly. Finally, the time comes for you to deliver your new bundle of joy. You make it through some angst of birth, see your new addition through tears of joy and relief and get ready for the onslaught of family and friends, who want to see the new arrival to your family. After you and your baby are cleared for discharge, off you go to your home, ready to begin your “new life” of nurturing, educating, parenting – aglow with images of pride, joy and a world of opportunities ahead. Hopefully, that’s exactly how we all hope it works out for you and your family.

To increase your odds that this scenario plays out, I would strongly suggest that you not take for granted the part about your epidural going smoothly. While there are probably many other questions you may think to ask – or should think to ask – here are three suggestions I have for you based on my seeing (as a lawyer) what can happen when the epidural doesn’t go smoothly.

How an epidural is performed

Here is one example available on the internet (YouTube) to show you just how an epidural is done. Unfortunately, it is a bit difficult to understand the speaker (at least for me), but having looked at several videos, I think it gives you a pretty good idea of how this procedure is performed by the anesthesiologist.

httpv://www.youtube.com/watch?v=_WRccCADReY&feature=related

“Have you reviewed my medical history, Doctor? Is there anything else I can tell you?”

Some of the known risks of having epidural anesthesia are connected to your medical history. Sure, you’re assuming that the medical history you gave to your OB during the prenatal visits and to the intake nurse when you arrived at the hospital has found it’s way to your medical record. You’re also assuming that your medical history has been carefully reviewed by the anesthesiologist whose about to put the epidural in your back. Is it there? Has it been carefully reviewed? Ask! There are conditions (e.g. spina bifida, scoliosis, certain heart valve problems, sickle cell anemia, etc.) that can increase your risk of a complication from an epidural.  Are you taking or have you recently taken any type of anti-coagulant such as heparin or coumadin? Make sure your anesthesiologist is aware if this is the case since these drugs can increase the risk of a bleeding complication. You don’t want to have a collection of blood around your spinal cord – believe me!

“When should I expect to move my legs or bend my knees? How long will I feel numb?”

In most instances, epidural are given to provide analgesia – pain relief (sensory block) during labor and at times for post-delivery (C-Section) pain relief. They are not intended to block your motor function – that is, your ability to move your legs, flex your ankles, wiggle your toes, flex your hips or bend your knees. During a C-Section the drugs being used for delivery are many times different drugs from the ones you are getting via your epidural infusion. You will have a different block so that surgery can be performed safely. You will likely have both a sensory and a motor block! You need to understand the difference.

These anesthesia drugs (the ones given during your surgery) will usually wear-off (varies depending on the drugs and from patient to patient) in a period of 1 to 4 hours. You will typically be in a post anesthesia care unit (PACU) during your recovery phase from anesthesia.

Key: you should not be discharged from the PACU if you are unable to at least bend your knees. There is a scoring system (Bromage) that the nurses and personnel in the PACU will typically use after examining your ability to move your legs, bend your knees, wiggle your toes, flex your hips, etc. to determine if you can safely be discharged from the PACU or if you need to be seen by a specialist in anesthesia to determine if you have a potentially significant complication.

“What exactly should I expect to feel like if I have an epidural running after I deliver my baby?”

I simply cannot stress enough how important it is for you to understand exactly how you should be feeling after you have been discharged from the PACU to your room. Don’t ask your family or friends; they don’t know – unless they are anesthesiologists. There are so many free, uneducated opinions out there that are simply wrong!

One further piece of advice: do not ask the nurse what you should expect to feel like. There is absolutely no doubt that there are many  very experienced and highly capable nurses out there taking care of moms. Unless you intend to ask for and analyze your nurse’s background, training and experience in anesthesia, don’t do it. The drugs used in administering epidural analgesia can vary significantly. The dosing (concentration, volume per hour, etc.) can also vary. Only a specialist in anesthesia can answer your questions correctly!

Know what to look for so that if there is some change in your condition or you start to encounter a feeling or loss of function or sensation, you can tell your nurse or doctor immediately so that you can be examined right away!

I suspect many parents are so caught up in the labor process, or are so exhausted after the delivery or so caught up in the wonderment of having their baby that these issues relating to an epidural may not be very important. If you are in your 20′s, 30′s or 40′s, how important is it to you that may not be able to walk for the rest of your life? It can happen – rarely, thank goodness, but it can happen. I have been involved in cases in which this is exactly what happened! Frankly – I don’t want to see it happen to anyone else. It is incredibly tragic for a mom, a dad and their child – trust me!

One last point before we leave this discussion on post-delivery (post-operative) analgesia. Some hospitals (the number appears to be declining due to concerns about the inadequacy of monitoring) use what is known as Patient Controlled Anesthesia epidural analgesia. Simply put, this is a device (they vary depending on the manufacturer) permits the patient to push a button a infuse a pre-determined dose of drugs (e.g. bupivacaine and fentanyl) into the epidural space for additional pain relief. A patient is actually limited as to how much drug can be used in the course of an hour (determined by what in called a lock-out interval and maximum dosing parameters per hour). While a fixed lower amount of drug flows each hour (known as the basal rate), many patients may require more relief than the basal rate provides.

That being said, if you find yourself pushing the PCA button numerous times during the course of an hour, you should bring this to the attention of your nurse or doctor. Don’t wait for them to hopefully check the machine to see how many times you pushed in the last hour (many forget to do this!). Be pro-active. If you are pushing your PCA button a number of times in the course of an hour, even though you can’t really overdose yourself because of pre-set limits by the anesthesiologist, this may be an indication that something needs to be checked. For instance, the catheter may have become displaced; the drugs may not be distributing equally; you may be having some problem that someone needs to investigate. Don’t keep hitting the PCA pump; hit the call button!

Get information about the risks, benefits and alternative to an epidural!

Having been there (i.e. childbirth) as a father four times, I know – at least from my perspective – how difficult it is to concentrate on issues such as risks, benefits and alternatives involving an epidural. Common sense tell me the ideal time to have this discussion simply cannot be while mom is in labor. If that’s the only chance you have, then fine – take the time and make the effort and have a real discussion with the anesthesiologist. Even if you just cover the 3 items I have suggested above, that will take you a long way.

I have made this suggestion before, but I’ll make it again: make arrangements to meet with someone from the anesthesia department before you get to the hospital to delivery your baby. Don’t be shy or concerned that you don’t want to bother anybody. Bother somebody! There really are an awful lot of wonderful doctors and CRNA’s, who would be willing to meet with you, educate you and answer your questions.  It’s your health,  your body, your future – so protect it!

There clearly are more than “3 questions” you should ask. Many of you have been through this. Many of you have medical training and experience. What questions do YOU think a mom-to-be should ask about their epidural.

 


 

5 Questions to Ask Your Obstetrician Before You Go to the Hospital

Wednesday, March 9th, 2011

Having our baby

Once the special moment comes for you to go to the hospital to deliver your baby, there’s so much that goes on that it just may not be the best time to remember questions you wanted to ask your obstetrician. I’ve been there four times – so, as they say, been there done that! I’ve also had a number of cases that made me stop and think – “I wonder if some of the issues that my clients encountered could have been avoided if they had asked some questions before they wound-up in labor in hospital?” As you can well imagine, that is perhaps not the best time for a Q and A session.

This past weekend, I posted somewhat of a survey on our Facebook Page and Twitter asking our friends, fans and followers what questions they wished they had asked their obstetricians before they arrived at the hospital. I also have a number of moms, who work in our law office; so I put the question to them as well. The responses received provided some interesting food for thought, which I thought I might share with those about to have their baby.

Who will be delivering my baby?

This was one of the most frequent questions making the list. A number of women complained that they wish they had known that their primary obstetrician was not going to be the delivering doctor. Turns out that physician was being covered the day/night these moms delivered. While they may have met all the members of the practice (if it was a group practice), they were not particularly happy when their primary obstetrician wasn’t there for the delivery. The problem is compounded when their primary obstetrician was off and being covered by someone they had never met before. Suggestion: find out as best you can what the chances are that there will be coverage by someone you’ve never met before you arrive at the hospital. You may want to make an appointment to meet that potential covering physician if this is a concern.

When will I see my obstetrician at the hospital?

One of the cases we are handling somewhat arose from a situation that raises this as an issue. You get to the hospital, you’re admitted, you’re placed in bed, monitor attached – you’re good to go. But – where’s your doctor? Does he/she even know you’re there? When is your obstetrician coming to see you? Several of the women who responded said this was a real concern and wished they had discussed this with their doctor before they sat in bed waiting and waiting for their doctor to arrive. They also wondered – if there was no direct phone call before going to the hospital, just how could they be sure their doctor was notified that they had arrived. In one instance, one obstetrician claimed she didn’t know the patient was even in hospital for more than 4 hours! This woman had to undergo an emergency C-Section when the doctor allegedly figured out she was there. Suggestion: confirm with the hospital staff after you arrive that your doctor has been notified that you have arrived and ask when you might expect for your doctor to arrive and examine you.

Who will be doing the circumcision of my baby boy?

A number of parents indicated that while they had discussed whether their newborn son would have a circumcision, it hadn’t crossed their minds to ask – “Who will be doing the procedure?” If this is an important consideration, and you would like an answer not only as to “who” but “what experience” they have, think about covering this with your obstetrician beforehand. While some physicians are very good at performing this procedure, others are not so good. There have been a number of infant penile injuries that we have happened in the hands of – well let’s say – less than skilled physicians.

What will happen if for some reason I require general anesthesia but I’ve recently had a meal?

One of the common orders for a patient who will undergo general anesthesia is that they be NPO (nothing by mouth – liberal translation) for hours prior to surgery. While you may have planned to have an epidural or natural childbirth, some conditions involving you and/or your baby (non-reassuring fetal heart tracing, placental abruption, etc) can occur that may change the “plan” and require that you undergo a different form of anesthetic management. Suggestion: if such a situation should arise, you will be seen by an anesthesiologist first. Perhaps you will have a discussion about possible alternatives for anesthetic management, but I can virtually assure you, that will not be the best time to have a coherent, meaningful discussion. Some have suggested, based on their experience, that asking for and having a meeting with anesthesia personnel before going to the hospital for delivery is time well spent. You can usually have such appointments made through your obstetrician’s office and have a meaningful discussion of the various alternatives, risks and complications at that time.

How long will the effects of my epidural anesthetic last after delivery?

It’s been pointed out to me that while some hospitals have discontinued the practice of providing pain relief (analgesia) post-partum by use of PCA (patient controlled analgesia) pumps, some hospitals still continue that practice. Regardless of what the hospital’s practice may be, there is usually a very consistent practice/protocol for when a woman who has had an epidural should be discharged from a recovery room/area. This is when she is able to bend her knees, move her hips and flex her feet in both directions. Suggestion: ask your obstetrician what his/her practice is for providing you pain management/relief after you deliver your baby. Will you have an epidural running to provide that relief? When should you expect to get return of your ability to use and feel your legs? Don’t guess – you could suffer what is known as a prolonged block, where the anesthetic, for various reasons, is taking too long to wear-off and affecting your neurological functioning. If your obstetrician doesn’t know, then consider talking to specialist in such pain relief techniques – the anesthesiologist at the hospital where you will be delivering your baby. While you’re there, you may also want to discuss what the risks, benefits and complications of epidural, spinal and general anesthesia are so that you are aware of these issues in advance.

What suggestions do you have?

This is only a partial list of a number of suggestions made by our readers and staff. What suggestions do you have? If you have already been through childbirth, are these matters or issues you wish you had discussed before you went to the hospital? If you are about to have your first child, are these issues, concerns or questions you might share? We – and our readers – would really like to hear from you. There is no substitute for experience – or so they say.
