Difficulty or inability to perform adequate bag-mask ventilation can be predictable in some patients, such as those with obvious facial trauma or beards that may interfere with obtaining an adequate seal. There are more subtle challenges-such as obstruction by the tongue, either by falling back or by swelling; airway edema or spasm; or blockage due to foreign body.

Difficult tracheal intubation can be related to the inability to visualize the glottic opening or those procedures requiring multiple and/or unsuccessful attempts to place the endotracheal tube. Reasons for these are many, including, but not limited to, upper airway edema, trauma, airway anomalies, obesity, limited neck mobility, or limited opening of the mouth. This could also be related to a lack of skill or use of improper technique by the practitioner. Without proper training in the endotracheal intubation procedure and/or proper use of a selected device, the practitioner can actually turn what could be a normal intubation procedure into a difficult one and increase the risk of complications to the patient as a result. To avoid this situation, practitioners expected to perform such tasks should first receive good basic training in the endotracheal procedure. They should then receive special training necessary for intubation pertinent to their patient population, followed by training for a specific device or technique in addition to standard laryngoscopy. No technique or device can replace good airway management training.

In Clinical Standards in Medicine medical expert witness Barry E. Gustin, MD, MPH, FAAEM, writes:

Although this clinical policy standardizes the approach to evaluating chest pain, the researchers responsible for its development emphasized its limitations stating that the reality of medical practice is that the physician is often gathering data, performing interventions and making decisions simultaneously, sometimes within a short period of time. Once again, the clinical policy is a reasonable standardized approach to the evaluation of chest pain but can never supersede the physician’s clinical judgement which, because of the immense number of clinical variables and continually changing circumstances, must be taken as the final word in making patient care decisions.

Clinical standard development is here to stay. Although they are a cause of consternation among many physicians because of their potential for use against physicians in medical malpractice lawsuits, they will, in the long run, help physicians continue to practice higher quality medicine, avoid malpractice, and more easily defend against frivolous or spurious lawsuits.

What constitutes a difficult airway? It is important to have an understanding of this and particularly what is causing the airway difficulties that you are experiencing in order to better understand which Plan B may be your best option. There is however, no single generally accepted definition of a difficult airway. For the purposes of its practice guidelines for the difficult airway, the American Society of Anesthesiology set a definition of a clinical situation in which a conventionally trained anesthesiologist experiences difficulty with face mask ventilation of the upper airway, difficulty with tracheal intubation, or both. The guidelines continue that an airway proven to be difficult is a combination of patient factors, the current clinical setting and the skill level of the practitioner performing the airway maneuvers.

In Clinical Standards in Medicine medical expert witness Barry E. Gustin, MD, MPH, FAAEM, writes:

For each of these rules, there are corresponding guidelines which may or may not be appropriate to act on. For example, under character of pain, it may or may not be useful to ask about the onset of the pain, the severity, the location, whether radiation occurs, its frequency, duration, similar previous episodes, precipitating or mitigating factors, its relationship to exertion, rest, movement or deep breathing and so on. It is clear to physicians that although this information is relevant for many patients presenting with chest pain, there are times when this information does not apply and has no real utility, such as the young otherwise healthy patient with fever who complains of chest pain only when coughing.

Similarly, there are no absolutes about what constitutes appropriate adherence to the guidelines for physical examination. A physician may decide, based on the overall clinical picture of the patient, to listen to the lungs, percuss the lungs, X-ray the lungs, assess the oxygenation of the lungs by doing pulse oximetry or arterial blood gases and so on. It would be left up to the physician to decide whether these things were or were not appropriate to do.

Leading brain injury expert Dr. Neil Martin of UCLA Medical Center says that even falling from a standing position is “a six-foot fall as far as your head is concerned” and that relatively minor accidents can prove fatal.

The first three hours following the onset of a critical health episode like a stroke are critical. If care is delayed beyond this critical time window, the chance of recovery or even survival declines substantially. Much of the first hour following the onset of these critical episodes is spent simply getting the patient to the emergency room. Then the patient must then be diagnosed, CT and MRI images and scans taken and developed. Finally, a specially trained physician must review the images and make a decision on the appropriate treatment protocol.

Dr. Martin is Founder/CEO of Global Care Quest and Chief of Neurosurgery at UCLA Medical Center. His company has developed a new wireless mobile technology that allows physicians to view CT and MRI images and scans from remote locations. This solution, ICIS Mobile, transmits images over high speed wireless networks to a physician’s cell phone or PDA.

Texas SB 362 which deals with voter identification has cleared the Texas Senate and will be sent to the Texas House. SB 362 will create a more secure election process and strive to ensure elderly and low income Texans who are eligible to vote are able to do so with minimal difficulty.

Bill Noble, a spokesman for SAFE Texas, a coalition of Texans dedicated to ensuring security and fairness in the election process, stated that fraud investigation expert witnesses supporting the bill demonstrated the difficulty in detecting and deterring voting fraud under the current system. “SB 362 is a major step forward in helping to detect and deter election fraud and assure Texas elections are secure and fair.”

In Clinical Standards in Medicine medical expert witness Barry E. Gustin, MD, MPH, FAAEM, writes:

One of the first clinical problems targeted for standards development was Chest Pain. As a prototypic example of clinical policy development, the Specialty Board responsible for the development and implementation of this standard created three conceptual entities which can be applied to all clinical problems. They are “actions”, “variables”, and “findings”.

Actions are defined as either “rules” (principles of good practice in most situations) such as ordering an electrocardiogram on an elderly patient with shortness of breath and severe chest pain, or “guidelines” (actions that should be considered but may or may not be performed depending on the patient, the circumstances, and a multitude of other factors) such as ordering imaging studies on any patient with chest pain. In those situations where a rule isn’t followed, the physician would be required to document in writing his justification for its avoidance.

In Clinical Standards in Medicine medical expert witness Barry E. Gustin, MD, MPH, FAAEM, writes:

Potential limitations should be recognized and dealt with such as the possibility that a particular standard becomes obsolete because of new discoveries or advances; or situations where environmental factors such as disaster, overcrowding, or multiple high acuity emergencies negate the applicability of standard clinical policies. Likewise, policy standards can never supersede the physician’s clinical judgement which must be taken as the final word in making patient care decisions. This is because of the immense number of clinical variables and continually changing circumstances in both stable and unstable patients with complex multifactorial systemic medical problems.

For maximum effectiveness and utility, it is clear that standards should be developed in the areas that place the patient at highest risk for death or debility. For the physician, these are often the areas of greatest liability. Also, it is important that standards are developed for common presenting complaints rather than for obscure uncommon entities. Finally, because cost-containment has become a central issue, clinical standards should also target those conditions or situations that may result in high charges.

In Clinical Standards in Medicine medical expert witness Barry E. Gustin, MD, MPH, FAAEM, writes:

The existence of clinical standards would enable malpractice litigators to be more selective in their choice of cases. In situations where a clinical standard was followed but where there was an adverse patient outcome, litigators would be less inclined to pursue the matter. In situations where deviation from clinical standards, the litigation process would still allow physicians to explain their reasoning and, in and of itself, is not de facto proof of negligence.

The actual development of clinical standards is complex, time consuming and expensive. In general, these standards should be developed by physician organizations, particularly the specialty societies utilizing appropriate ancillary input from administrators, economists, etc. They should be based on current information and clinical experience and be as comprehensive and specific as possible. They should be periodically reviewed and revised and widely disseminated.

McClatchy Company, the third largest newspaper company in the US, reports that America’s five largest banks, which already have received $145 billion in taxpayer bailout dollars, still face potentially catastrophic losses from exotic investments if economic conditions substantially worsen, their latest financial reports show.

Corporate governance expert witness and president of Everest Management Gary Kopff has scrutinized the big banks’ financial reports. He noted that Citibank now lists 60 percent of its $301 billion in potential losses from its wheeling and dealing in derivatives in the highest-risk category, up from 40 percent in early 2007. Citibank is a unit of New York-based Citigroup. In Monday trading on the New York Stock Exchange, Citigroup shares closed at $1.05.
