Question: Abstract: Artificial ventilation is a cornerstone of basic life support-cardiopulmonary resuscitation (BLS-CPR). Recent data corroborate clinical studies performed in the 1950s and 1960s, suggesting a need to change the present American Heart Association standards for artificial ventilation. These studies show that gastric insufflation followed by regurgitation and pulmonary aspiration are a major hazard of artificial ventilation with an unprotected airway. Present BLS-CPR standards require that ventilation be performed rapidly between external chest compressions or with incremental breaths. These methods of ventilation predispose the victim to gastric insufflation. Alternative methods of ventilation with longer inspiratory time and thus lower flow rate and peak inspiratory pressure are suggested. Additionally, rescue personnel, particularly EMTs and paramedics, should be taught how to apply cricoid pressure to prevent gastric insufflation in victims with an unprotected airway.
Which is the apt title for the abstract? option1: Alternative methods of ventilation during respiratory and cardiac arrest. option2: Chromosomal location of the genes encoding complement components C5 and factor H in the mouse.

Answer: Alternative methods of ventilation during respiratory and cardiac arrest.

Question: Abstract: Anticoagulation is the cornerstone in the treatment of deep vein thrombosis. However, the treatment of septic deep vein thrombosis is controversial. Unlike septic superficial vein thrombosis, venous excision is often associated with limb-threatening or even life-threatening complications. Some authors have suggested thrombectomy as the only means of resolving the sepsis. We reviewed our experience with seven patients who had septic deep vein thrombosis. Phlebography or noninvasive studies documented deep vein thrombosis and blood cultures were positive in all patients. The mean age was 31.5 years with a male/female ratio of 5:2. All patients were treated with anticoagulants and intravenous antibiotics. One patient required surgical exploration for associated abscess of the groin. The patients became afebrile with normal white blood cell counts from 3 to 18 days after therapy was begun. No cases of recurrent sepsis occurred. We conclude that antibiotic therapy and anticoagulation are adequate treatment and therefore consider venous thrombectomy unnecessary.
Which is the apt title for the abstract? option1: Septic deep vein thrombosis. option2: Polymicrobial bacterial sepsis and defective neutrophil chemotaxis in an infant with cystic fibrosis.

Answer: Septic deep vein thrombosis.

Question: Abstract: During the early development of atriopulmonary anastomotic operations (Fontan-Kreutzer), a number of physiologic and anatomical limits were proposed by the Fontan group as selection criteria. Among 167 consecutive patients undergoing modified Fontan procedures from 1973 through 1985, 109 (65%) patients exceeded one or more of the original selection criteria in areas of age, anomalies of systemic or pulmonary venous connection, pulmonary artery distortion, and pulmonary artery pressure. Twenty-six patients had a mean pulmonary artery pressure greater than 15 mm Hg, with 16 operative survivors (62%). Nineteen patients had anomalies of systemic and/or pulmonary venous connection, and 16 survived (84%). There were 44 patients under the age of 4 years, and 26 survived (59%). Twenty-five patients were older than 15 years, and 23 (92%) survived the Fontan procedure. Pulmonary artery distortion, relating to prior palliative operations, was found in 34 patients. Seventeen of these 34 survived a modified Fontan procedure (50%). Twenty-six patients had a pulmonary arteriolar resistance more than 2 Wood units times square meter, and 14 survived (54%), whereas 81 of 93 with a pulmonary arteriolar resistance of less than 2 U X m2 survived (87%). Multivariate analysis showed that pulmonary arteriolar resistance and pulmonary artery distortion had a significant, negative impact on survival, but age and anomalies of systemic and/or pulmonary venous connection did not. Pulmonary artery pressure was not an independent predictor of outcome. The results show that the original criteria may be exceeded in the areas of age and anomalies of pulmonary or systemic venous connection. Pulmonary artery pressure alone should not contraindicate a Fontan procedure if pulmonary arteriolar resistance is low. Pulmonary artery distortion from a prior palliative operation and elevated pulmonary arteriolar resistance increase the risk of a Fontan procedure.
Which is the apt title for the abstract? option1: Extending the limits for modified Fontan procedures. option2: Is surgery by nonsurgeons in the public's interest? [editorial]

Answer:
Extending the limits for modified Fontan procedures.
