The Anesthesiologist’s Story: New Details Emerge In the Joan Rivers Case

Jan 4, 2015• 31

By KAREN SIBERT, MD

New York Post reporter Susan Edelman revealed on January 4 the name of the unfortunate anesthesiologist allegedly present on August 28 at Yorkville Endoscopy, during the throat procedure that led to the death of comedian Joan Rivers. She is reported to be Renuka Reddy Bankulla, MD, 47, a board-certified anesthesiologist from New Rochelle, NY.

Having her name made public will be a nightmare for Dr. Bankulla, as investigators will certainly target her role in Ms. Rivers’ sedation and the management — or mismanagement — of her resuscitation.

When the news of Ms. Rivers’ cardiac arrest and transfer to Mt. Sinai Hospital became public, many of us guessed that there might have been no qualified anesthesia practitioner — either anesthesiologist or nurse anesthetist — present during the case. The gastroenterologist and then medical director of the clinic, Dr. Lawrence Cohen, argued famously that the sedative propofol, which Ms. Rivers received, could be safely given by a registered nurse under his supervision, and that no anesthesiologist is necessary.

However, with the publication of the Centers for Medicare & Medicaid Services (CMS) report of September 5, it became clear that an anesthesiologist was definitely present. The anesthesiologist was identified only as “Staff #2″ in the report. She was interviewed by the CMS surveyors four days after the event, but said she was “advised by her legal representative not to discuss the case.”

Key pieces of information about what happened still haven’t been made public. Nonetheless, the surveyors gathered enough information to reach this conclusion: “The physicians in charge of the care of the patient failed to identify deteriorating vital signs and provide timely intervention during the procedure.”

By any standard of care, the anesthesiologist clearly would be one of the physicians in charge.

No Mystery: Arizona Execution Lengthy Due to Drug Choice

Jul 26, 2014• 11

By KAREN SIBERT, MD

There’s no mystery about why the July 23 execution of Joseph Wood in Arizona took so long. From the anesthesiologist’s point of view, it doesn’t seem surprising that the combination of drugs used—midazolam and hydromorphone—might take nearly two hours to cause death.

Here’s why.

The convicted murderer didn’t receive one component of the usual mixture of drugs used in lethal injection: a muscle relaxant. The traditional cocktail includes a drug such as pancuronium or vecuronium, which paralyzes muscles and stops breathing. After anyone receives a large dose of one of these powerful muscle relaxants, it’s impossible to breathe at all. Death follows within minutes.

But for whatever reason, the Arizona authorities decided not to use a muscle-relaxant drug in Mr. Wood’s case. They used only drugs that produce sedation and depress breathing. Given enough of these medications, death will come in due time. But in the interim, the urge to breathe is a powerful and primitive reflex.

So-called “agonal” breathing, which precedes death, may go on for minutes to hours. The gasping or snoring that eyewitnesses described would be very typical. People who are unconscious after overdoses of heroin try to breathe in a similarly slow, ineffective way, before they finally stop breathing altogether or are rescued by emergency crews.

More about the drugs

Midazolam is a member of a class of drugs called benzodiazepines. The common “benzos” that many people take include Valium, Xanax, and Ativan. What these drugs have in common is that they produce relaxation and sleep. You might take a Xanax pill, for instance, to help you nap during a long flight.

In anesthesiology, we use benzodiazepines for another important reason: because they produce amnesia. There are stories of people taking a Valium to relax a little before they give an important talk, and the next day panicking because they can’t remember if they actually showed up and gave the talk.

Amnesia can be very helpful in my business. Many of my patients don’t want to remember coming into the operating room and seeing the bright lights and surgical instruments. After I inject one or two milligrams of midazolam into the IV, they’re often smiling and relaxed, and they have no memory later of coming into the operating room at all. The next thing they know, surgery is over and they’re waking up.

A Doctor’s Guide to Botched Executions

May 13, 2014• 11

By Karen S. Sibert, MD

I give what could be lethal injections for a living.

That’s right. Nearly every day I give someone an injection of midazolam, vecuronium, and an IV solution containing potassium chloride–the three drugs in the “cocktail” that was supposed to kill convicted murderer Clayton Lockett quickly and humanely in Oklahoma.

Here’s the difference between an executioner and me. I use those medications as they are intended to be used, giving anesthesia to my patients, because I’m a physician who specializes in anesthesiology. Midazolam produces sedation and amnesia, vecuronium temporarily paralyzes muscles, and the right amount of potassium chloride is essential for normal heart function. These drugs could be deadly if I didn’t intervene.

My job is to rescue the patient with life support measures, and then to reverse the drugs’ effects when surgery is over. The “rescue” part is critical. When Michael Jackson stopped breathing and Dr. Conrad Murray didn’t rescue him in time, propofol–another anesthesia medication–turned into an inadvertently lethal injection.

When anesthesia medications are used in an execution, of course, no one steps in to rescue the inmate. This gives new meaning to the term “drug abuse”. In my opinion, the whole concept of lethal injection is a perversion of the fundamental ethics of practicing medicine.

Not for amateurs

Though lethal injection is supposed to be more humane than the electric chair or the gas chamber, often it doesn’t work as planned. Mr. Lockett died on April 29 after the injection of midazolam, vecuronium, and potassium chloride into his system. It is unclear from media reports how much of which drug he actually received. Apparently, prison staff had difficulty finding a vein.

The drugs were injected, they thought, into the large femoral vein in Mr. Lockett’s groin, which should have killed him within moments.

The Problem of Pain: When Best Medical Advice Doesn’t Equal Patient Satisfaction

Apr 4, 2014• 23

By Karen S. Sibert, MD

The problem of pain, from the viewpoint of British novelist and theologian C. S. Lewis, is how to reconcile the reality of suffering with belief in a just and benevolent God.

The American physician’s problem with pain is less cosmic and more concrete. For physicians today in nearly every specialty, the problem of pain is how to treat it responsibly, stay on the good side of the Drug Enforcement Administration (DEA), and still score high marks in patient satisfaction surveys.

If a physician recommends conservative treatment measures for pain–such as ibuprofen and physical therapy–the patient may be unhappy with the treatment plan. If the physician prescribes controlled drugs too readily, he or she may come under fire for irresponsible prescription practices that addict patients to powerful pain medications such as Vicodin and OxyContin.

Consider this recent article in The New Republic: ”Drug Dealers Aren’t to Blame for the Heroin Boom. Doctors Are.” The writer, Graeme Wood, faults his dentist for prescribing hydrocodone to relieve pain after his wisdom tooth extraction.

As further evidence of her misdeeds, he says, first she “knocked me out with propofol–the same drug that killed Michael Jackson.” Wood uses his experience–which sounds as though it went smoothly, controlled his pain, and fixed his problem–to bolster his argument that doctors indiscriminately hand out pain medications and are entirely to blame for patient addiction.

But what happens to doctors who try not to prescribe narcotics for every complaint of pain, or antibiotics for every viral upper respiratory infection? They’re likely to run afoul of patient satisfaction surveys. Many hospitals and clinics now send a satisfaction questionnaire to every patient who sees a doctor, visits an emergency room, or is admitted to a hospital.

The results are often referred to as Press Ganey scores, named for the company that is the leading purveyor of patient satisfaction surveys. Today these scores wield alarming power over physician incentive pay, promotion, and contract renewal.

Now hospital payments are at risk too.

Why a New Healthcare Technology Designed to Cut Costs and Increase Efficiency Probably Won’t Put Anesthesiologists Out of Work

Jul 30, 2013• 5

By Shirie Leng, MD

The Wall Street Journal recently contacted me regarding an upcoming article on Sedasys, the new gadget that is supposed to be able to infuse propofol by computer while monitoring vital signs.

If you’ve read anything I’ve written previously, you’ll know that I am NOT a big proponent of technology as a means of “improving” patient care. To me, the more technology you put between the patient and the caregiver, the less medicine you’re practicing, and the more data-entry and computer programming you’re doing.

Sedasys is designed specifically to administer propofol. Propofol is a milk-like substance that produces a range of effects from sedation to general anesthesia. For sedation you just use less, for general anesthesia you use more. Its very quick onset and very quick recovery make it great for outpatient sedation. It has to be given in a continuous drip because its effect goes away so fast. GI docs love it because its so effective. I suspect they also love it because propofol comes with an anesthesiologist to give it.

The only problem is the one Michael Jackson encountered: it has this pesky side effect of causing you to stop breathing. And you can’t tell by looking at a person how much will sedate them and how much will make them stop breathing.

A little old lady with a million health problems might sedate at, say, 40 mg and stop breathing at 60 mg, while an 19-year-old could probably take 150 mg and still be fighting you. It’s not necessarily weight-based.

An Anesthesiologist Thinks Out Loud

Jun 5, 2013• 14

Anyone who has read my work knows that articles like the one written in the New York Times on Sunday by Elisabeth Rosenthal will immediately get a response out of me. If you haven’t read it, here’s the link.

Where do I start with this??? I’m going to let Ms. Rosenthal tell you about how many unnecessary colonoscopies we do. I’ll let her tell you how much more it costs here than anywhere else. I will address the anesthesia bit. Let me tell you a little story. When I was a baby anesthesiologist my hospital sent anesthesiologists “downstairs” to do anesthesia for GI procedures maybe once a week for a few hours.

This was in 2004 or so. Now we send three board certified anesthesiologists to various GI units every day all day. We do maybe 25 cases a day on average. Now, some of this is due to the aggressive expansion of the advanced GI procedures unit as well as the addition of an outside private group that was recently folded into the greater hospital system. It’s also because we’re there. It’s no accident that as soon as we committed troops to the GI battle all of a sudden everybody needed anesthesia.

The NYT article uses Dierdre Yapalater as an example, a healthy 60-something. Putting aside the ridiculous cost for the overall procedure, she was billed $2,400 for anesthesia. But she didn’t need anesthesia. There is absolutely no reason for her to have an anesthesiologist involved for that case. None.

Anesthesia care used to be limited to very sick patients, not because they are harder to sedate (they’re actually often easier) but to monitor them closely because of their tenuous physiologic status. Now everybody is getting it. Why did she get anesthesia, why did the anesthesiologist give it, why does insurance pay for it?
