E-cigarettes prove effective for smoking cessation

E-Cigarettes Shown Effective as Smoking Cessation Aids Electronic cigarettes or e-cigarettes use battery power to vaporize a solution, usually containing nicotine dissolved in propylene glycol, glycerin, or polyethylene glycol, creating a puff of “smoke” that dissipates harmlessly. E-cigarettes deliver a hit of nicotine (about 1/4 to 1/2 that of a cigarette puff), but their vapor [… read more]

Vasopressors for septic shock (Surviving Sepsis Guidelines)

Vasopressors for Septic Shock (Surviving Sepsis Guidelines) See All the Surviving Sepsis Guidelines Vasopressors are provided for septic shock that does not respond to fluid resuscitation. Norepinephrine (Levophed), epinephrine, vasopressin, phenylephrine (Neo-Synephrine), and dopamine are the most commonly used vasopressors for septic shock. To achieve adequate fluid resuscitation, the Surviving Sepsis Guidelines advise at least 30 ml/kg [… read more]

Surviving Sepsis Guidelines: Diagnosis of Sepsis and Septic Shock

Diagnosis of Severe Sepsis and Septic Shock (from the Surviving Sepsis Guidelines) See all the Surviving Sepsis Guidelines Sepsis is defined as an infection (definite or suspected) with systemic manifestations (any 2 from a list). This definition may seem overly broad — it means that many people with colds and self-limited viral syndromes have sepsis [… read more]

Vasopressin, steroids, epinephrine cocktail improved cardiac arrest outcomes

Adding Vasopressin, Steroids to Epinephrine Improved Cardiac Arrest Outcomes Contrary to what watching TV or even reading the newspaper will lead one to believe, outcomes after in-hospital cardiac arrest are very poor. Only about 1 in 5 survive to leave the hospital after cardiac arrest, and most survivors suffer significant cognitive impairment; up to half suffer [… read more]

How to manage lung cancer when resection is high risk

Management of Lung Cancer in High Surgical Risk Patients By Blair Westerly, MD We all hope that surgical resection is an option for our unfortunate patients diagnosed with lung cancer.  However, as a consequence of the epidemiology of stage I non-small cell lung cancer, the standard of care, lobectomy with systematic mediastinal lymph node evaluation, [… read more]

Low tidal volume ventilation reduces complications from abdominal surgery

Low Tidal Volume Ventilation Improves Outcomes in Elective Surgery Using low tidal volumes (6-8 mL/kg ideal body weight, or about 500 mL in the average man) during mechanical ventilation has been known for more than a decade to be lifesaving for people with acute respiratory distress syndrome (ARDS). Since reducing mortality by a relative 22% [… read more]

Riociguat for Pulmonary Hypertension: New Kid on the Block

New Pulmonary Hypertension Drug Riociguat Proves Effective Pulmonary arterial hypertension is a rare but life-threatening illness affecting around 10,000 people in the U.S., in which ongoing remodeling of the pulmonary vasculature leads to narrowed pulmonary arteries with increased pulmonary artery pressure (pulmonary hypertension), and if untreated, eventual right heart failure and death. (The overwhelming majority [… read more]

Riociguat improves chronic thromboembolic pulmonary hypertension (CTEPH)

Riociguat Improves Chronic Thromboembolic Pulmonary Hypertension (CTEPH): CHEST-1 Chronic thromboembolic pulmonary hypertension (CTEPH) is an uncommon complication of pulmonary embolism, in which the pulmonary blood vessels become occluded by the body’s ongoing reaction to residual blood clots. The result is slowly worsening shortness of breath, pulmonary hypertension, and eventually right heart failure. People with chronic [… read more]

How to ration lung cancer screening CTs, rationally

Restrict Lung Cancer Screening CT To Highest-Risk People? The National Lung Screening Trial showed that 3 annual low-dose chest CT scans in people with heavy smoking histories (30+ pack-years) saved lives, reducing the risk of death from lung cancer by a relative 20% compared to screening with annual chest X-rays. With 160,000 lung cancer deaths [… read more]
